Problems solved by technology

Existing drying equipment has strict requirements on the initial moisture of materials, such as single-cylinder rotary dryer, double-cylinder rotary dryer, and three-cylinder rotary dryer. When the initial moisture of the material to be dried is greater than When it is 35%, it is difficult for the equipment to dry it, especially in winter in the cold region of Northeast China; moreover, the drying efficiency is low and the drying cost is high
Therefore, when using existing drying equipment to dry materials with a high moisture content of more than 40%, it is necessary to perform drying or filter press treatment before the drying operation to remove part of the moisture. When the moisture content reaches the initial moisture required by the drying equipment, the drying operation will be carried out. In this way, the equipment investment will be increased, and the floor area will be large, the treatment cycle will be long, secondary pollution will easily occur, and energy consumption and operating costs will be high.

Abstract

The invention discloses a frying, drying and cooling three-section type dryer for high-moisture materials, and relates to the technical field of biomass drying equipment. The dryer comprises a frying section, a drying section located at the downstream of the frying section and a cooling section located at the downstream of the drying section; the frying section is provided with a high-temperature flue gas box body; high-temperature flue gas generated by the high-temperature flue gas box body is used for drying materials in the drying section, and the cooling section is provided with a cooling cylinder; and a frying cylinder is arranged in the high-temperature flue gas box body, and a frying section stir-frying plate is arranged in the frying cylinder.

Description

technical field [0001] The disclosure relates to the technical field of biomass drying equipment, in particular to a frying, drying and cooling three-stage dryer suitable for high-moisture materials. Background technique [0002] At present, in the fields of resource utilization of residues such as agriculture, forestry, food industry, brewing industry, traditional Chinese medicine industry, and edible fungus cultivation industry, the drying equipment used for these industrial residues mainly includes single-cylinder rotary dryers, Double cylinder rotary dryer, three cylinder rotary dryer. Existing drying equipment has strict requirements on the initial moisture of materials, such as single-cylinder rotary dryer, double-cylinder rotary dryer, and three-cylinder rotary dryer. When the initial moisture of the material to be dried is greater than When it is 35%, it is difficult for the equipment to dry it, especially in winter in the cold northeast region; moreover, the drying...
