In-place turning-throwing type aerobic solid fermentation tank

Abstract

The invention belongs to the fields of fermentation engineering and equipment, and in particular relates to an in-place turning-throwing type aerobic solid fermentation tank. The solid fermentation tank comprises a temperature-controllable and wind-controllable interlayer, a reciprocating type spiral stirring device for turning-throwing fermentation, and a temperature control spray device used forinoculation and liquid feeding. The in-place turning-throwing type aerobic solid fermentation tank is characterized in that the interlayer is arranged on the bottom of the fermentation tank, so thatthe temperature of introduced air and the ventilation quantity can be controlled, and the oxygen aeration of materials in the tank and the regulation on the temperature of the materials are facilitated. In addition, the device is provided with the spray device moving synchronously with a reciprocating type turning-throwing device, so that feed liquid is sprayed at any time while the materials aresubjected to uniform turning-throwing, and in-place inoculation, adjustment on pH and water replenishing can be realized. Meanwhile, the device is provided with a temperature-controllable liquid storage barrel, so that the temperature of the materials can be stabilized or regulated during the feed liquid adding process. For the device provided by the invention, the mechanization of in-place inoculation, adjustment on pH and water replenishing and turning-throwing of the materials is simultaneously realized, and the technological parameters including the temperature, pH, water and oxygen content during the aerobic solid fermentation process can be strictly regulated.

Description

technical field [0001] The invention belongs to the field of fermentation engineering and equipment, and in particular relates to an in-situ turning and throwing aerobic solid fermentation tank. Background technique [0002] Solid fermentation is easy to operate, low energy consumption, low degree of sterility, simple process control, has many advantages and good development potential. At present, solid fermentation has been widely used in the production of probiotics, enzyme preparations and feed protein, waste treatment and biological deodorization and other fields. However, the automation degree of solid fermentation is low, the process control process is extensive, and the traditional solid fermentation equipment is often unable to achieve ventilation and temperature control at the same time. Difficulty of control. [0003] Patent CN202175670U discloses a "A Horizontal Solid Fermentation Tank". The equipment is equipped with a multi-layer unit stirring system, which ca...
