Problems solved by technology

Therefore, controlling the fermentation temperature in the liquor cellar is of great significance to the product quality of the refined liquor. However, the existing methods for controlling the fermentation temperature in the liquor cellar are all to roughly control the entire cellar, and the effect of temperature control is not ideal. There is still room for improvement in yield and quality

Embodiment 3

[0106] A temperature control device is installed in a liquor solid-state fermentation cellar with a length of 4.1m, a width of 2.0m, and a depth of 1.8m. Select the described temperature control device described in embodiment 1 or embodiment 2. Two kinds of heat exchange plates with a length of 4m and a width of 2m and a length of 2m and a width of 2m used in the wall of the cellar are cast, two each, and the distance between each heat exchange tube of the heat exchange plate is 40cm. 2-3 temperature sensors are installed on the board. Then cast two sets of heat exchange frames (6 heat exchange frames in total) used in the three-layer cellar. Each heat exchange frame is 1.8m long, 1.6m wide, and 0.6m high. The serpentine tubes are separated by 40cm, and 3-5 temperature sensors are installed at different positions on each heat exchange surface of the heat exchange frame. The temperature sensor and temperature monitor transmit the temperature data of each area to the temperatu...

Abstract

The invention discloses a method and a device for controlling solid-state fermentation temperature of white spirit. By adopting the method, a solid-state fermentation pit is divided into a plurality of regions, a temperature control device is arranged inside the pit, and the temperature of each region is respectively controlled. By adopting the method, the product quality can be improved, and the fermentation time is shortened. The device is simple in structure, and temperature of different regions inside the pit can be controlled by respectively adjusting the temperature and the flow velocity of a heat-transfer medium in each heat exchange tube; a heat-transfer frame and distilled grains filled into the heat-transfer frame achieve overall hoisting when entering into the pit and discharging out of the pit by using the heat-transfer frame in the device for controlling the fermentation temperature inside the pit, repeated treading and treading with large workload when the feeding and discharging operations of the distilled grains are carried out by using a travelling crane and a grab bucket in the prior art are reduced, the workload is greatly reduced, and the labor cost is saved.

Description

technical field [0001] The invention relates to a method and a device for controlling the solid-state fermentation temperature of liquor, belonging to the technical field of liquor production. technical background [0002] The solid-state fermentation of liquor is based on the cellar as the carrier, the fermented grains as the raw material, natural inoculation, and the synergistic effect of various microorganisms. A series of complex material and energy metabolism processes are carried out in the three phases of solid, liquid, and gas (grass, fermented liquid, and fermented gas) in the cellar. Studies have shown that temperature has an important impact on the fermentation production of fermented grains. Temperature has an important influence on the growth and metabolism of various microorganisms in the fermentation process of fermented grains. The high-temperature accumulation fermentation process can enrich the types and quantities of microorganisms in the cellar, and can ...
