High-quality finished carbon is expected by every user and manufacturer. We can judge the quality of charcoal by judging the color, shrinkage, hardness, crack and steel sound of charcoal. This is also the standard of high-temperature carbon and low-temperature carbon. One. As a user of Shuliy, how to judge the quality of charcoal made by small charcoal making machine equipment?
The higher the standard requirement, the longer the burning time of the kiln and the higher the furnace temperature requirement. The more serious the burning of charcoal will be, the lower the natural carbon removal rate will be. Many customers are familiar with the carbon quality of charcoal machine equipment, but the quality of the finished carbon is not accurate.
Using the senses to simply judge the quality of charcoal:
1. Charcoal length. Under normal circumstances, the length of charcoal packing should be more than 5cm.
2, carbon diameter (shrinkage), at present most domestic charcoal machine equipment manufacturers use 5cm diameter forming sleeve standard, so the finished carbon diameter should be below 4cm, with 3.5-3.8 as * shrink size.
3, charcoal color, if the charcoal is pure black from the outside, if the color is black, the knocking sound is not crisp, indicating that there is a wet water problem, the water content will exceed the standard. The charcoal can be broken to observe the color of the section. If there is yellowing, it means that there are too many carbon impurities, or the carbonization process is not standard.
Charcoal has a smell of smoke (charcoal taste does not necessarily have a smoke, but smoke must have a taste), and tasteful charcoal has a certain influence on industries such as food processing industry and mosquito coil production. This is the obvious phenomenon of incomplete carbonization.
When the carbon rod is carbonized, when the kiln temperature reaches a certain level, a hard carbon film is formed on the surface of the charcoal and the inner hole. This black hard film will thicken as the kiln temperature increases. Observe this layer. The film can naturally see the charring heat of the charcoal. High-temperature charcoal and low-temperature charcoal are also easily judged.
4, hardness, holding the carbon rod with one hand upright, the thumb can not easily break the standard. The better the hardness, the better the quality of the charcoal.
5, steel tone, two pieces of charcoal hit the building, can send a crisp metal tone
6, cracks, charcoal allowed a small amount of cracks, does not affect the quality of charcoal. However, the crack is too large, indicating that the density of the semi-finished wood stick is not good or the oxygen supply during the carbonization process is too large, so that the crack cannot be completely shrunk.
It is important to produce high quality charcoal to purchase good quality equipment. It is also important to master the carbon making skills. The investment in charcoal machines is low, and the benefits are fast. This is the fact that the demand for charcoal is increasing and profits will continue to heat up.
