Tofu is a delicious bean product, which is made from soybean. In the process of making tofu, heating soybean milk and drying dried soybean require a lot of heat energy. Bao straw biomass burner has been widely used in the production of tofu in Pingjiang County, Hunan Province, which greatly improves the automation of heating and barbecue, saving worry and effort.

Bao straw biomass particle combustor uses biomass particles made of corn stalk, wheat stalk, rice stalk, rice husk, sawdust and firewood powder as fuel, which not only saves money, but also solves the problem of environmental pollution in haze weather caused by burning straw to a certain extent, so as to truly achieve energy conservation and environmental protection.

The equipment has automatic ignition, automatic blanking, intelligent temperature control, no need for manual tracking, and saves labor cost. At present, the precious straw dryer has been widely used in tobacco curing, pepper drying, tea drying, traditional Chinese medicine drying, mushroom drying and other fields. It has been donated to Liangshan area of Sichuan Province to solve the problems of difficult baking and poor baking quality of local farmers, which has been widely recognized and highly endorsed.
