Making charcoal with a charcoal machine is simple to say. There are also many tips. It is difficult to make charcoal without mastering the techniques.
First of all, the first process is pulverization. The pulverizer is the simplest. Put the materials into the pulverizer and crush them. It should be noted that when installing the shredder, the base must be hit and fixed with screws, otherwise, the speed of the shredder motor will be very fast, and the constant vibration of the shredder will affect production.
The second step is drying. Many people think that sawdust or sawdust is very dry and does not need to be dried. In fact, the sawdust that ordinary people look very dry does not meet the requirements for making rods. Even if it is brown, grab it with your hands, it feels crispy, and hold it hard. Spreading the sawdust will loosen naturally and will not make a stick, you can make a stick. Pay attention to the size of the fire during the drying process. If the fire is too strong, the sawdust in the pipe may be burned. If the fire is too small, the drying effect may not be achieved. This experience must be accumulated slowly.
The third step is to make rods. The technology of making rods is much more difficult. First of all, the temperature must be adjusted. Generally, the temperature should be adjusted to 280 to 300 degrees at the beginning. After the rods are out, normal production is started and then lowered. Adjust the temperature to about 260 degrees. The reason why the temperature needs to be raised is that at the beginning of production, when the material is fed into the hopper, the temperature will drop sharply by dozens of degrees, and the lowered temperature is just suitable for production. At this time, the front end of the propeller must be manually pressed with a wooden stick. It can be returned to the material and can be produced naturally after normal production, without hands. The rod making machine has a wearing part, which is the propeller. The front end of the propeller is in a high-temperature and high-pressure position. Long-term feeding and forming will cause the front end to wear. At this time, it is necessary to re-weld and grind it before production. The welding rod, the angle and the thickness of the welding mill are all tricks. One of them is that a manufacturer like Shuliy charcoal machine sends technicians to teach welding and grinding technology, and the other is that the charcoal factory staff must work for a long time and slowly explore the experience.
The last step is carbonization. Carbonization has several points. First, when the fire is closed, the furnace door and the near fire mouth must be completely closed, and no trace of air can be penetrated, otherwise, the char will be burned into ashes. The second is to turn on the condenser at the appropriate time to purify the black smoke generated during the conversation and extract the wood tar from it. This also requires some experience.

No additives needed for making charcoal
We all know that for making charcoal, most of its raw materials are sawdust, tree branches, and other wood materials, and finally, through the process of crushing, drying, making sticks, and carbonizing, the wood raw materials become black charcoal. Many friends are curious about this process, especially when using a stick making machine, watching the dry raw materials instantly become dense semi-finished salary sticks, thinking about whether certain additives are added to it. So, do we need additives for the production of charcoal?
If we carefully watch the video of the charcoal machine production process recorded by our factory, we will know that the whole process has not added any additives. The reason why raw materials can be squeezed into salary sticks is because these raw materials have a common feature, that is, they contain certain lignin, and this lignin will soften and liquefy when it reaches 200-300 degrees Celsius, as long as a certain pressure is applied It is closely adhered to cellulose and cemented with adjacent particles, and can be solidified after cooling. And the rod-making machine equipment produced by our factory uses the characteristics of lignin to squeeze the raw materials containing lignin into semi-finished products that we need, and then put them into a carbonization furnace for carbonization to produce finished charcoal.
However, some customers have seen or heard that some equipment needs to add additives during the molding process. What I want to say is that they use a toner molding machine instead of a rod making machine, and their raw materials and processes are different. The carbon powder molding machine is to add crushed carbon and other additives to extrusion molding to realize the recycling of crushed carbon.
In summary, whether or not additives are needed to make charcoal depends on what equipment is invested and what raw materials are used. However, in general, most of the customers who produce charcoal invest in charcoal machine equipment. The production process does not require additives. If customers do not understand, they can visit our factory and explain in detail.

Automatic rice mill for your health
many of us know that eating is simply to measure, to satisfy hunger, but they are don't know the true meaning of eating is to urge nutrition. Rice is our staple food and a crucial source of nutrition for us, but does one really skills to eat rice?
The expiry date of rice
Rice not only features a time period but also a time period, does one know?
Indica rice (hulled rice) are often stored for 3 years, but rice can only be kept fresh for 45 days.
Rice milling machine website:https://rice-machinery.com/15t-d-integrated-rice-milling-unit/
Jain is that the armor of rice, and therefore the skin is that the protective clothing of rice. Together they form the protective layer of rice, in order that rice can maintain life for an extended time. Once hulled, the rice begins the oxidation process of fresh rice-new rice-Chen rice.
With the rise of storage time, the rice features a reduced nutritional value and taste. the interior enzyme activity is reduced, and therefore the structure gradually relaxes. After the rice is broken, it's very easy to grow bugs. If not stored properly, not only will the first color and fragrance be lost, it's going to even become moldy. Therefore, the earlier you eat rice, the higher.
Fresh rice source
Loquat rice source must be the rice within the current season. The so-called rice within the current season is that the rice within the time from harvesting to storage not exceeding the beginning of the subsequent season. additionally, rice isn't immune to the storage, and storage and freshness is a particularly critical part; rice storage must meet the six requirements of controlling rice moisture, removing rice impurities, graded rice storage, rice ventilation, and cooling, and closed rice grain piles to really guarantee rice. Nutritional value and edible quality.
Unhulled rice features a longer time period and may better lock the nutrition of the rice. At an equivalent time, it can fully absorb the remaining nutrients within the ears of rice during storage. Fresh and sold "fresh rice" is typically milled without further processing. One is clean. the opposite is that it retains a part of the cortex and germ. it's rich in B vitamins, minerals and dietary fiber, which may strengthen the physical body. Immunity, especially for controlling blood glucose, regulating gastrointestinal function, constipation and obesity, has many benefits. The "fresh rice" milled by the rice within the season can cause you to smell the rich and fragrant rice that you simply haven't experienced before. once you cook the rice, it'll be more oily, chewy, and sweet. Fresh rice is eaten with natural origin and long-lost food.
Automatic rice mill
Automatic rice mills are welcomed by consumers during a more intelligent, convenient and fast way. the entire process takes only three minutes, and enough rice are often taken home easily for a couple of days, thus achieving "fresh rice" from the sector to the board in just 100 meters. Freshly ground germ rice, freshly ground and sold, it's true that every grain is fresh rice, and therefore the germ of the rice is retained to make sure the simplest nutritional status and taste of the rice. Its freshness is like freshly picked fruits.

How to maintain the rice mill? How do I troubleshoot?
How to operate and maintain the rice mill?
Boot
1. Before starting, the foreign material in the feeding hopper and the whitewashing room must be cleaned. At the same time, the equipment should be checked for materials that affect the driving or other foreign materials that affect the equipment. There should be no object jamming. exclude.
2. When the machine is turned on, wait for the equipment to run normally when it is empty, and then feed and process. When adjusting the flow and accuracy, pay attention to the power load. Do not overload the control and close the ammeter. The weight of the pressure on the pressure door should be based on a variety of materials and the required accuracy. Make adjustments, or replace the rollers with different weights (When the rice is first started, if the rollers are adjusted too quickly, it will easily cause a blockage.
Using
(1) Reasonably select supporting power. Generally, the rice mill is required to work under nearly full load, and the motor can fully exert its power under full load. Reasonable selection and matching of the motor can not only ensure that the rice mill can fully function, but also save energy and improve efficiency.
(2) Adjustment of entrance and exit gates. The inlet sluice is widened and the outlet sluice is closed. When the whitening room grains increase, the pressure increases and the beige is crushed, but there is more broken rice. Therefore, the inlet and outlet gates must be well coordinated. The inlet gates control the flow and the outlet gates control the accuracy.
Three, rice knife adjustment. It is mainly to adjust the gap between the rice knife and the sand roller. If the gap is large, the pressure in the white milling room is small, and the frictional force of the rice grains is not strong. Therefore, the rice cannot be finely milled, but the rice yield is higher; otherwise, the accuracy is improved, but the Broken rice rate is higher.
Four, rice sieve adjustment. If you find whole rice mixed with fine bran during work, you should check the rice sieve for rice leakage.
26. After the production is completed, the inlet gate should be closed first, and after one minute of operation, the rice in the rice milling room is milled and the materials are completely removed before closing.

How to effectively reduce smoke emissions from charcoal machines
The processing mechanism of charcoal first faces environmental issues. the way to solve the matter of flue gas emissions in charcoal production?
The first is to completely solve the smoke exhaust problem of the charcoal kiln. This method is extremely thorough and doesn't have any flue gas exhaust. The disadvantage is that the investment is large and therefore the supporting equipment must be installed when the factory is made. The smoke is recovered, and therefore the smell of burning wood remains there. Basically, it is often smelled about 20 meters from the charcoal kiln, but the smoke is not any longer visible. Therefore, it's best to possess independent courtyards far away from residential areas. And currently, the Environmental Protection Agency also recognizes this smoke recovery method, which may be described as once and for all.
website:https://charcoalmachines.com/charcoal-machine-production-line/
The second method is to use biomass pyrolysis technology to supply charcoal. The flue gas produced by this method is quite 50% less than that of the traditional charcoal kiln. it's suitable to be used in charcoal plants with independent yards far away from residential areas, because only a little amount of smoke is generated when the charcoal production equipment is ignited after basically 2 hours, so this method also can effectively solve the present smoke problem in charcoal production.
The third method is suitable for a way to unravel the matter of smoke emission during the assembly of mechanical charcoal. In fact, because the raw materials and production process of mechanical charcoal is different from traditional raw charcoal, we will process consistent with the characteristics of mechanical charcoal production and therefore the characteristics of raw materials. Optimization and reorganization of carbonization project, effectively solving the mechanism of charcoal's smoke emission during the rod making and firing process. at present, all mechanism charcoal production has undergone process reorganization and process optimization. The smoke generated during the charcoal production process is compared with traditional the assembly of machine-made charcoal is almost 40% lower, and therefore the production cycle of machine-made charcoal is shortened, and therefore the yield and quality of machine-made charcoal have also improved significantly.

Dealing with problems during operation of charcoal machine
1. the rationale why the kiln doesn't turn off: the sole reason for this problem is that the kiln leaking air. Solution: the answer is extremely simple, and repair the leaks in time.
2. Reasons for poor carbon shrinkage or insufficient hardness: There are two main reasons:
a. The carbonization process is just too fast. b. The temperature isn't high enough. Solution:
A. The carbonization process is just too fast: too fast carbonization will inevitably cause cracking of charcoal. Once the charcoal cracks an excessive amount of, it'll be difficult to shrink. cannot be too high. Generally don't exceed 300 degrees.
Website:https://charcoalmachines.com/charcoal-machine-production-line/
B. Insufficient temperature for heating: When the temperature of coal smelting is elevated, the temperature doesn't reach the specified temperature. Generally, the charcoal can shrink well only the temperature of charcoal reaches 800 degrees or higher. the upper the temperature of charcoal, the higher the shrinkage. However, the upper the temperature, the lower the speed of charcoal and therefore the higher the value. it's generally recommended to boost the temperature to 800 degrees.
3. Reasons for several carbon cracks: mainly the temperature of the carbonization process is just too high, or it's going to be an inherent defect of the wood chip stick. Solution: If it's not an inherent defect brought by the wood chip stick, then you want to concentrate to control the temperature of the carbonization process, and therefore the temperature of the carbonization process shouldn't exceed 300 degrees. If it's an inherent defect of the wood chip stick, please attend the molding question answer in Chapter 4 to seek out an answer .
4. Reasons for top carbon volatility: the sole reason is that the temperature isn't enough. Solution: Please extend the heating time and lift the temperature above 800 degrees.
5. Exceeding the quality of carbon ash features a great impact on the chemical quality of carbon. Not only can products not be exported, but even domestic sales are affected in severe cases.
Reason: the most reasons are as follows: A, the staple isn't clean, B, the staple features a high ash content, C, the carbonization temperature is high, and therefore the temperature rise time is just too long.
Solution: A. The raw materials aren't clean: On the one hand, the most method to unravel this problem is to regulate the transportation process of the raw materials to make sure that the raw materials aren't polluted during transportation; on the opposite hand, to regulate the storage conditions of the raw materials and check out to avoid wind and sand and soil. Pollution. At an equivalent time, the source of raw materials must be controlled. B. The ash content of the raw materials is high: for instance, the ash content of rice husks, straws, weeds, etc. is comparatively large, therefore the ash content of the charcoal is comparatively large. Generally speaking, the charcoal can't be utilized in barbecues. The industry can only be utilized in industry. C. High carbonization temperature: If the temperature within the carbonization process is just too high, the carbon element will escape with the mixture of hydrogen and oxygen. during this way, the carbon is going to be relatively light, and therefore the ash won't escape, which suggests that the ash content of the carbon Relatively increased. D. Warming up time is just too long: an equivalent as above.
6. Reasons for insufficient carbon heating value: There are many specific reasons, like high ash content, the low carbon content in raw materials, high volatile content, insufficient carbonization, insufficient carbon temperature, etc. Solution: The temperature didn't reach the specified temperature during the carbon refining. Generally, the charcoal can shrink well only the temperature of charcoal reaches 800 degrees or higher. the upper the temperature of charcoal, the higher the shrinkage. However, the upper the temperature, the lower the speed of charcoal and therefore the higher the value . it's generally recommended to boost the temperature to 800 degrees.

How is charcoal made?
Carbonization is one of the most important processes in charcoal production. It is not the most expensive, but it requires the most experience. Some people say that the carbonization process is the risk of charcoal production. If you control carbonization, your entire charcoal production process will save a lot of costs and reduce waste of resources.
No matter if you use raw wood to produce charcoal or wooden corner waste to make mechanical charcoal, their raw materials are theoretically wood. If the moisture content of the wood is too high, the charcoal content of the produced charcoal will be low, so it cannot be regarded as good quality charcoal. The main thing we say about charcoal is its charcoal. If the content of charcoal is low, what charcoal is called and what is the value of use, do you think this is the reason? So no matter what method or raw material you use to produce charcoal, it is best to dry the raw material. Dry raw materials are one of the primary guarantees for producing good quality charcoal.
During the entire carbonization process, the wood is maintained at a temperature of about 100 ° C or lower in the carbonization equipment. At this temperature, the moisture in the wood is evaporated until it is zero, and then the burning temperature of the wood is raised to 280 ° C. This step The energy comes from some wood burning heat absorbed by some carbonization equipment, it is an energy absorption or endothermic reaction.
When the wood is dried and heated to about 280 ° C, a pyrolysis reaction occurs, and the wood begins to decompose into charcoal, water vapor, methanol, acetic acid and more complex chemicals, mainly in the form of tar and non-condensable gases composed of hydrogen, carbon monoxide and carbon dioxide. Air is controlled in the kiln during this process, and the oxygen in it is absorbed by the combustion of wood to become carbon dioxide, so there is still nitrogen in the kiln.
The wood continues to burn in the charcoal kiln. This process is called an exothermic reaction. As the exothermic reaction continues, the temperature in the kiln is maintained at about 280 ° C. When it continues to burn, it will leave black lumps in the charcoal kiln. This is charcoal. Due to the low carbonization temperature of the charcoal produced in this way, unless a further external heat source is provided, the maximum temperature in the kiln is about 400 ° C. The fixed carbon content of this charcoal is about 65% -70%, and the ash content is 3-5. %, But it will have a high volatile content. The volatile content of different tree species may be different, but it will generally reach 30%. By further heating, the fixed carbon content of charcoal will increase, and the volatile matter will be decomposed. The temperature in the kiln reaches 500 ° C, the carbon content of charcoal will rise to 85%, and the volatile matter content will drop to about 10%. At this temperature, The charcoal production is about 32% -35% of the weight of the wood. Therefore, the theoretical yield of charcoal varies with temperature, and the volatile tar content in charcoal is also related to the carbonization temperature.
When burning charcoal, the lower the carbonization temperature, the more volatile components of the produced charcoal. As a result, there will be an acidic taste when burning charcoal. This is because charcoal contains a large amount of acidic corrosive tar. This charcoal makes barbecue charcoal, which will change the taste of food, and there will be flames when it is calcined. Good commercial charcoal should be charred at a temperature of about 500 ° C, and about 75% of the fixed carbon.
The production of charcoal is also related to the quality of the raw materials. Good wood has higher lignin content because of its hard wood. In theory, the harder wood is more suitable for producing charcoal, and the harder wood is more suitable for producing charcoal. However, when carbonizing in a charcoal kiln, it is not necessary to put more wood as dense as possible, because if the wood is placed too densely, the wood will be easily broken during carbonization, because the temperature in the kiln rises too quickly and the volatile content decreases. The brittleness of charcoal. Basically, a temperature of 450 ° C to 500 ° C is the best balance between firing charcoal and maintaining a fixed charcoal.
There are many factors that affect the charcoal production and the conversion rate of wood charcoal. Often the charcoal capacity is too low or the waste of raw materials is caused by many factors. Then we try to avoid the factors that may cause problems. Usually we can choose some harder wood as the raw material for charcoal. The firewood should be as dry as possible, and the wood with a diameter of more than 20cm must be split and burned. Otherwise, it is easy to produce charcoal slag and scraps and waste wood materials. When burning charcoal, we must pay attention to the balance of temperature in the charcoal kiln. It is necessary to make the whole kiln reach a carbonization temperature of 500 ° C, but sometimes this is difficult because the irregular air flow in the charcoal kiln causes many raw materials to be burned into charcoal And some are still new. To improve the charring efficiency and quality of charcoal, a well-designed charcoal kiln is very important. A good charcoal kiln not only has good air tightness, but also has a balanced air flow, which does not appear: "cold spots", and the overall temperature in the kiln can quickly rise to a carbonization temperature of 500 ° C.
No matter if you use raw wood to produce charcoal or wooden corner waste to make mechanical charcoal, their raw materials are theoretically wood. If the moisture content of the wood is too high, the charcoal content of the produced charcoal will be low, so it cannot be regarded as good quality charcoal. The main thing we say about charcoal is its charcoal. If the content of charcoal is low, what charcoal is called and what is the value of use, do you think this is the reason? So no matter what method or raw material you use to produce charcoal, it is best to dry the raw material. Dry raw materials are one of the primary guarantees for producing good quality charcoal.
During the entire carbonization process, the wood is maintained at a temperature of about 100 ° C or lower in the carbonization equipment.

The fixed carbon content of this charcoal is about 65% -70%, and the ash content is 3-5. %, But it will have a high volatile content. The volatile content of different tree species may be different, but it will generally reach 30%. By further heating, the fixed carbon content of charcoal will increase, and the volatile matter will be decomposed. The temperature in the kiln reaches 500 ° C, the carbon content of charcoal will rise to 85%, and the volatile matter content will drop to about 10%. At this temperature, The charcoal production is about 32% -35% of the weight of the wood. Therefore, the theoretical yield of charcoal varies with temperature, and the volatile tar content in charcoal is also related to the carbonization temperature.
When burning charcoal, the lower the carbonization temperature, the more volatile components of the produced charcoal. As a result, there will be an acidic taste when burning charcoal. This is because charcoal contains a large amount of acidic corrosive tar. This charcoal makes barbecue charcoal, which will change the taste of food, and there will be flames when it is calcined. Good commercial charcoal should be charred at a temperature of about 500 ° C, and about 75% of the fixed carbon.
The production of charcoal is also related to the quality of the raw materials. Good wood has higher lignin content because of its hard wood. In theory, the harder wood is more suitable for producing charcoal, and the harder wood is more suitable for producing charcoal. However, when carbonizing in a charcoal kiln, it is not necessary to put more wood as dense as possible, because if the wood is placed too densely, the wood will be easily broken during carbonization, because the temperature in the kiln rises too quickly and the volatile content decreases. The brittleness of charcoal. Basically, a temperature of 450 ° C to 500 ° C is the best balance between firing charcoal and maintaining a fixed charcoal.
There are many factors that affect the charcoal production and the conversion rate of wood charcoal. Often the charcoal capacity is too low or the waste of raw materials is caused by many factors. Then we try to avoid the factors that may cause problems. Usually we can choose some harder wood as the raw material for charcoal. The firewood should be as dry as possible, and the wood with a diameter of more than 20cm must be split and burned. Otherwise, it is easy to produce charcoal slag and scraps and waste wood materials. When burning charcoal, we must pay attention to the balance of temperature in the charcoal kiln. It is necessary to make the whole kiln reach a carbonization temperature of 500 ° C, but sometimes this is difficult because the irregular air flow in the charcoal kiln causes many raw materials to be burned into charcoal And some are still new. To improve the charring efficiency and quality of charcoal, a well-designed charcoal kiln is very important. A good charcoal kiln not only has good air tightness, but also has a balanced air flow, which does not appear: "cold spots", and the overall temperature in the kiln can quickly rise to a carbonization temperature of 500 ° C.
