A belt-type solid-state continuous fermentation tank and solid-state fermentation method

Abstract

The invention provides a belt type solid continuous fermentation tank and a solid fermentation method, and belongs to the technical field of solid fermentation. The belt type solid continuous fermentation tank and the solid fermentation method aim at solving the problems that in the prior art, fermented grains cannot realize first-in first-out; the fermentation temperature, the PH and the strain concentration cannot be regulated in time; the material layer is too high; the fermented grains are compactly pressed. A feeding opening is formed in the upper side of the length direction of the upper end of a fermentation casing; a discharging opening is formed in one side, far away from the feeding opening, of the lower end of the fermentation casing; the lower end of the fermentation casing is provided with a plurality of slurry water outlets; a material loosening device is arranged in the position of the feeding opening; the back side of the material loosening device is provided with a scraper in the vertical direction; a position sensor is arranged on the scraper; a temperature measurer is arranged at the upper part of each of the two sides of the fermentation casing; one end of a feeding sealing auger is in lap joint in the position of the feeding opening; the other end of the feeding sealing auger is connected with a hopper; a discharging sealing auger is arranged in the position of the discharging opening; a transmission unit is in belt transmission, and is arranged on the lower casing arranged inside the fermentation casing; a spraying unit is arranged on the upper casing positioned inside the fermentation casing.

Description

technical field [0001] The invention belongs to the technical field of solid-state fermentation, and in particular relates to a belt-type solid-state continuous fermentation tank and a solid-state fermentation method. Background technique [0002] At present, the production of light alcohol and liquor by the solid-state method generally adopts the traditional cellar-type underground fermentation. The temperature method requires a very long fermentation time, and the solid-state fermentation of pool-type light alcohol is very labor-intensive. [0003] In recent years, the technology and equipment for producing light alcohol by continuous solid-state fermentation have been developed, such as horizontal rotary fermenters and vertical continuous fermenters. There are problems in the horizontal rotary continuous fermentation tank that the fermented wine grains can never achieve the first-in-first-out effect, and the fermentation temperature, pH, and strain concentration cannot b...
