Airing bed used for solid fermentation of food

Abstract

The invention relates to an airing bed used for solid fermentation of food. The airing bed comprises a bracing frame which is provided with a conveying mesh belt laid out in a closed loop manner and a driving mechanism used for driving running of the conveying mesh belt; and the airing bed also comprises a set of an air supply system and a material turning system which are mutually cooperated, wherein the air supply system comprises a fan and an air supply pipe which are mutually connected, the air supply pipe is arranged below the conveying mesh belt, the upper part of the air supply pipe is provided with an air outlet, the air outlet points to the conveying mesh belt, and a material turning area of the material turning system is located in an upper surface area of the conveying mesh belt to which the air outlet points. The airing bed provided by the invention conveys a material by using the conveying mesh belt; the material is stirred and turned by the air supply system and the material turning system, so the material is cooled and surface moisture is rapidly volatilized; an accessory material adding system can add accessory materials into the material; a dynamic material temperature measurer can detect the temperature of the material in real time; and the whole process does not need direct participation of workers, so the material is prevented from pollution and the workers are prevented from risks of burns.

Description

technical field [0001] The invention relates to a drying bed used for solid-state fermentation of food. Background technique [0002] The food solid-state fermentation process includes the steps of cooking the grain material and spraying boiling water, and then the material needs to be turned and cooled to reduce the temperature of the material and evaporate the water on the surface before proceeding to the next step. The traditional method of operation is to pile the boiled materials on the ground, then manually pour boiling water on the materials, and then the workers use a shovel to sprinkle the materials several times to make the materials cool and dry on the surface. The production efficiency of such an operation process is low, and the labor intensity of the workers is high. When the workers operate, the materials are easily contaminated, and there is also a hidden danger of personnel being scalded by high-temperature materials. Contents of the invention [0003] Th...
