Continuous disinfection device for lactic acid fermentation

Abstract

The invention discloses a continuous disinfection device for lactic acid fermentation, which belongs to the field of lactic acid production and manufacturing and aims to solve the problems of low heat utilization ratio, poor continuity, high disinfection cost and the like. According to the continuous disinfection device for the lactic acid fermentation, materials which are not disinfected enter an ejector through a heat exchanger A, the ejector is connected with a maintaining tank material inlet, a maintaining tank material outlet is connected with the heat exchanger A through a pipeline and is connected with a fermentation tank through a material outlet of a heat exchanger B, a T-shaped guide tube is arranged on the top of a maintaining tank, a viewing mirror is arranged on one end of the upper part of the T-shaped guide tube, a blowoff valve is arranged on the outer side of the viewing mirror, and the other end of the upper part of the T-shaped guide tube is connected with a sterile compressed gas tank through a control valve. The continuous disinfection device has the beneficial effects that less loss of nutrient substances is guaranteed, the phenomena of overheating, incomplete sterilization and the like are avoided, the heat utilization ratio is increased, the cost is reduced, the disinfection workload is reduced, and the disinfection cost is reduced.

Description

technical field [0001] The invention relates to the field of lactic acid production and manufacturing, in particular to a lactic acid fermentation continuous disinfection device. Background technique [0002] In recent years, due to the continuous improvement of fermentation technology and the continuous expansion of fermentation scale, this has put forward requirements for the sterilization process of lactic acid medium. The continuous sterilization (continuous sterilization) process of lactic acid medium is widely favored because of its many advantages and thus meets these process requirements. Heating, heat preservation and cooling, and then entering the sterilized fermenter. However, in the prior art, there are often the following problems, such as: the first is that the heat cannot be recycled. Before the material enters the continuous elimination process, the lactic acid medium needs to be preheated and sterilized with steam. Finally, it needs to be cooled with cooli...
