Why charcoal machine equipment is so popular

Why are charcoal machines so popular? Our factory recently sent staff to investigate. After investigation, we found that most people prefer to use straw charcoal machines rather than ordinary charcoal machines. Why is straw charcoal machine more popular than ordinary charcoal machine? In fact, to be honest, I didn't understand the answer at the beginning. I think many people are the same, but we can analyze the difference between the two products. According to the analysis of the two kinds of carbon making raw materials of the charcoal machine, the ash content of the raw materials of the charcoal machine reaches a certain level, and the raw materials used by the straw charcoal machine, such as branches and straw, are all highly rated.
