Multi-layer reciprocating chain belt type bran steaming machine

Abstract

The invention relates to the technical field of wine brewing, and discloses a multi-layer reciprocating chain belt type bran steaming machine. The bran steaming machine comprises a base, wherein multi-layer box body is arranged at the top of the base, a multi-layer chain belt conveying device is arranged in each layer of the box body, the operation directions of the upper multi-layer chain belt conveying device and the lower multi-layer chain belt conveying device are opposite, and an upper cover is fixedly installed at the top of the multi-layer box body. According to the multi-layer reciprocating chain belt type bran steaming machine, steam is introduced into the space between the first layer and the second layer and the space between the third layer and the fourth layer, the steam penetrates through a material layer, and waste gas is exhausted from the upper portion of the first layer, between the second layer and the third layer and between the fourth layer and the fifth layer to be discharged, so that the purpose of steaming removal is achieved; and cold air enters from the space between the fifth layer and the sixth layer, penetrates through the material layer from top to bottom and then is discharged, and the flowing directions of steam or air between every two adjacent layers are opposite from top to bottom, so that the problem of non-uniform heating due to vertical ventilation of the material layer in the prior art is solved, and the steaming and cooling effects are greatly improved.

Description

technical field [0001] The invention relates to the technical field of winemaking, in particular to a multi-layer reciprocating chain-belt bran steamer. Background technique [0002] The bran shell is an indispensable solid filler and leavening agent in the brewing of Chinese liquor, especially Luzhou-flavor liquor. It not only provides a space supporting environment with a large specific surface area for the proliferation and metabolism of microorganisms in the fermentation process of glutinous rice grains, but also It provides a bulky mass transfer space for the volatilization and concentration of aroma components in the process of "mixed steaming and co-firing" of glutinous rice grains. The bran husk for winemaking comes from the relatively complete mixture of chaff and germ obtained after threshing of rice. Since the bran shell is easily damp and moldy during storage and transportation, and the bran shell itself contains a lot of raw bran and bitter substances, in the a...

Problems solved by technology

[0003] At present, the most widely used steaming equipment in the market is batch operation, which has low operation efficiency and high energy consumption.

There are also a small number of tunnel-type continuous operation models, but there are defects such as large footprint, high energy consumption, uneven heat transfer, poor steam removal effect, and high failure rate. For this reason, we propose a multi-layer reciprocating chain Belt steamer
