Abstract

The invention relates to a belt-like annular flow drying machine. The belt-like annular flow drying machine comprises a feeding section (2), an intermediate section (3), a tail section (5), an upper-layer conveyor belt (10), a lower-layer conveyor belt (9), a circulating fan (11), a cooling section (7), a discharging section (6) and a cooling fan (12), wherein the feeding section (2), the intermediate section (3) and the tail section (5) are sequentially connected to form an integral housing; one side of the cooling section (7) is connected with the discharging side of the integral housing, the other side of the cooling section (7) is connected with the discharging section (6), the lower-layer conveyor belt (9) is communicated with the discharging section (6) through the cooling section (7), a gap (13) communicated with atmosphere is formed below the cooling section (7), a gas collecting hood (14) is arranged above the cooling section (7), and an outlet of the gas collecting hood (14) is connected with an air inlet of the cooling fan (12). The belt-like annular flow drying machine disclosed by the invention has the advantages of good drying effect, high drying efficiency and small difference between material temperature after drying and environmental temperature.

Description

technical field [0001] The invention relates to a device for drying materials by using hot gas, in particular to a belt type circulation dryer. The invention belongs to the technical field of material drying equipment manufacturing and processing, and is especially suitable for material drying in industries such as food, feed and grain. Background technique [0002] The belt circulation dryer in the prior art includes a machine body, a conveyor belt located in the body and a fan. The material to be dried is placed on the conveyor belt, and the hot gas passes through the conveyor belt under the action of the fan, and the material to be dried is placed on the conveyor belt. The materials are dried. [0003] Such as: Chinese Patent Publication No. CN102121783A discloses a belt-type circulation dryer, the drying belt is laid with a material layer, the air distribution chamber is below the conveyor belt, and the outlet air duct of the circulating fan is vertically connected wit...
