Vermicelli drying device

Abstract

The invention discloses a vermicelli drying device. The vermicelli drying device comprises a variable frequency adjustable speed auger, a hot blast stove, an air heat exchanger, a induced draft fan, a desulfurization-denitration tower, a regulating tank, a chemical storage tank, a drying room, an air heater and cutting blast caps, wherein two ends of the variable frequency adjustable speed auger are connected with a coal feeding hopper and the hot blast stove, the air heat exchanger is arranged at the top of the hot blast stove, the top of the air heat exchanger is connected with a flue and the inlet of the induced draft fan, external housings are arranged at the lower part of the heat exchanger and outside the hot blast stove, the outlet of the induced draft fan is connected with the desulfurization-denitration tower through a pipeline, an atomizing pump and the regulating tank which is connected with the chemical storage tank are arranged below the desulfurization-denitration tower, the air heater is arranged at the bottom of the external housing of the hot blast stove, a hot blast pipeline connected with the air heater leads to the drying room, the multiple cutting blast caps are arranged on the hot blast pipeline in the drying room, and a vermicelli conveyor chain is arranged in the drying room. The vermicelli drying device disclosed by the invention improves the drying intensity, shortens the drying time, increases equipment efficiency, saves energy consumption and has good quality of processed vermicelli.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a vermicelli drying equipment. Background technique [0002] At present, there are two traditional drying techniques for vermicelli processing. One is to use natural drying. Such vermicelli has poor hygienic conditions. In addition, it is affected by the weather and cannot achieve continuous production. At the same time, the production capacity is low and the drying time is long. It meets the needs of large-scale production, and requires a lot of labor, and the cost is high; second, with the development of the vermicelli industry, a vermicelli drying process has emerged, which is used in the drying room, using steam or hot water coils to make As a heat source, fans are used to blow air and fans to dehumidify the vermicelli. This process improves the efficiency of drying vermicelli compared to drying, but it is a waste of energy. Contents of the invention [0003] The purpose of ...
