Constant temperature heating system for fermentation tank

Abstract

The invention discloses a constant temperature heating system for a fermentation tank. The constant temperature heating system comprises a fermentation tank false bottom arranged at the tank bottom ofthe fermentation tank, and a juice circulation mechanism arranged inside the fermentation tank, wherein a heating space is arranged between the fermentation tank false bottom and the tank bottom of the fermentation tank, a heating mechanism is arranged in the heating space, an input end of the juice circulation mechanism is arranged inside the heating space, an output end of the juice circulationmechanism is arranged on the top of the fermentation tank, and the constant temperature heating system further comprises temperature sensors respectively for detecting the material temperature in thefermentation tank and the temperature in the heating space. According to the constant temperature heating system, the fermentation tank false bottom is installed at the bottom of the fermentation tank to separate a solid substance in the fermentation tank from a liquid, and thereby the heating and flow of the liquid are facilitated. The heating mechanism is arranged to heat the liquid under the fermentation tank false bottom to provide a heat source for materials, and when the material temperature is lower than a preset value, a heated juice in the heating space under the fermentation tank false bottom is pumped up by the juice circulation mechanism and sprayed on the top of the materials to keep the materials at a set temperature.

Description

Technical field [0001] The invention relates to the field of material fermentation, in particular to a constant temperature heating system for a fermentation tank. Background technique [0002] In the condiment fermentation industry, larger fermentation tanks are used. The fermentation tanks are generally of concrete structure, embedded 3-5 meters below the ground. The process of material fermentation in the fermentation tank is the decomposition and transformation process of organic matter by microorganisms under aerobic or anaerobic conditions. The environment temperature when the microbial activity is best is higher than normal temperature, so it needs to be heated and maintained This temperature environment is generally 35-38°C. [0003] At present, there are generally two ways to maintain the temperature of the fermentation tank. One is to install a steam coil directly in the fermentation tank. Due to the high steam temperature, this method will cause the microorganisms near ...

Problems solved by technology

[0003] At present, there are generally two ways to maintain the temperature of the fermentation tank. One is to directly install a steam coil in the fermentation tank. Due to the high temperature of the steam in this way, the microorganisms near the steam pipe will lose their activity directly due to the high temperature, and cannot The organic decomposition and transformation of the fermented product leads to poor overall fermentation effect; secondly, the method of heat preservation with interlayer water in the fermentation tank requires high technical requirements for the construction of the fermentation tank, complex structure and high construction cost
