Abstract

The biomass drying method and plate biomass drying machine belongs to the field of biomass regeneration and reuse pre-treating technology. By means of the plate biomass drying machine as one special apparatus, high temperature gas is blown into sealed tank to dry biomass while the biomass moves towards the discharge port inside the sealed tank. Meanwhile, humidity from the drying process is led out. Inside the sealed tank, material moves in zigzag mode, and combined heat transferring mode including radiation, convection and conductance is adopted in high drying efficiency and high drying effect.

Description

technical field [0001] The invention belongs to the technical field of biomass regeneration and utilization pretreatment, and in particular relates to a biomass drying method for drying biomass such as crop stalks and its special equipment-a plate-type biomass dryer. Background technique [0002] Biomass resources include crop waste, fuelwood and forestry waste, poultry manure, biological waste, etc., ignoring some small biomass resources such as industrial wastewater and waste residues, only crop waste, fuelwood and forestry waste, For the four items of poultry manure and biological waste, the exploitable amount is quite large, about 437 million tons of oil equivalent. Crop straw is the largest biomass energy resource in my country. With the development of rural economy, the output of crop straw in my country is increasing year by year, with an average annual growth rate of 2.33%. By 1995, my country's crop straw output reached 604 million tons, equivalent to more than 300...
