Biological fermentation tank

Abstract

The invention relates to a biological fermentation tank. A three-level retractable air cylinder is fixed to the top of the tank, a cleaning and pressing filter plate is horizontally placed on the top of the tank, a sealing strip is arranged on the position where the cleaning and pressing filter plate is in contact with the tank, and the retractable end of the three-level retractable air cylinder stretches into the tank and is fixedly connected with the cleaning and pressing filter plate; one or two variable frequency motors are fixed to the upper end portion of the cleaning and pressing filter plate, stirring rods which are equal to the variable frequency motors in number are arranged below the cleaning and pressing filter plate, and rotating shafts of the variable frequency motors are connected with the stirring rods and used for driving the stirring rods to stir fermentation raw materials; one opening is formed in one side of the tank, a suspension plate capable of being pulled out from the tank is horizontally arranged on the lower portion of the tank, and a fermentation material discharging port is formed in the bottom of the tank; an openable venting port and an openable water spraying port are formed in the top of the tank; a transparent observation window is arranged on the side wall of the tank, and the side wall of the tank is provided with a feeding port in a sealed connection mode; the biological fermentation tank is reasonable in structural design, easy to operate and capable of being used and popularized in the technological filed of the biology.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a biological fermentation tank body. Background technique [0002] The biological fermentation device is the most commonly used basic equipment in bioengineering production. Whether the design of the biological fermentation device is reasonable will directly affect the product quality. But the existing products all have some deficiencies in this respect: 1. Most of the existing fermentation devices are provided with only one cleaning hole, and there is a blind spot when cleaning the inside of the tank body, resulting in incomplete cleaning, and it is difficult to adapt to products with higher quality requirements. 2. Most of the existing fermentation devices can only provide the same fermentation temperature environment as the external temperature, and the external temperature is constantly changing, which makes the microorganisms in the fermentation t...

But the existing products all have some deficiencies in this respect: 1. Most of the existing fermentation devices are provided with only one cleaning hole, and there is a blind spot when cleaning the inside of the tank body, resulting in incomplete cleaning, and it is difficult to adapt to products with higher quality requirements. 2. Most of the existing fermentation devices can only provide the same fermentation temperature environment as the external temperature, and the external temperature is constantly changing, which makes the microorganisms in the fermentation tank unable to maintain a suitable fermentation environment for a long time, resulting in The problem of low fermentation efficiency and changes in the composition of fermentation products; 3. When using the existing fermenter for fermentation, the problem of insufficient stirring limits the improvement of fermentation efficiency; 4. It is impossible to observe the reaction of materials in real time when using the existing fermenter
