Drying technology is the method of crop drying, pepper, tea, walnut, mushrooms and other crops are dried by dryer. Different from the traditional sun drying, the dryer can realize indoor drying operation, which is not affected by the weather and site factors. The dryer is composed of heat energy equipment and drying room. Of course, there are some crops that do not need drying room, such as Zanthoxylum bungeanum.

Pepper drying need to use heat energy equipment and drying pool, drying pool can use cement and bricks for stacking, do not need to spend money to buy drying board room, more convenient and cost-effective. According to the size of Zanthoxylum bungeanum pool and the way of stacking, the corresponding biomass combustion machine and heat energy equipment can be equipped for drying.

Compared with air energy heat pump, biomass pellet burner uses corn stalk, wheat stalk, rice stalk, sesame stalk, cotton stalk, sawdust, firewood powder and other waste straw as fuel, which not only has low cost, but also solves the problem of haze weather environmental pollution caused by burning straw to a certain extent, and truly achieves energy conservation and environmental protection.

The combustion machine of baocao biomass pellet is controlled by microcomputer, with automatic ignition, automatic feeding and automatic temperature control. It does not need to be watched manually and saves labor cost.
