Seed tanks can be understood as containers for storing or producing seeds. They are fermentation equipment and are currently used in pharmaceutical, monosodium glutamate, enzyme preparation, food and other industries.
The stainless steel seed tank is a reaction device suitable for microbial growth. In the seed tank, various microorganisms grow, metabolize and form fermentation products in a suitable environment.

1. Product usage range of seed jars

The seed tank is suitable for fermentation, brewing, condiments, pharmaceuticals, chemicals and bacterial cultivation of yogurt and lactic acid bacteria beverage mother liquor. It can be understood as a culture tank or fermentation tank. Its function can be heating, insulation and cooling. It is a fully enclosed and hygienic fermentation specialized equipment. . Seed jars are currently suitable for pharmaceutical, monosodium glutamate, enzyme preparation, food and other industries.

2. Product usage range of seed jars

Seed tank characteristics: The materials are all made of imported 304 or 316L. The seed tank has the advantages of energy saving, noise reduction, corrosion resistance, high productivity, and easy cleaning and operation.

3. Product classification of seed jars

Classification of seed tanks: There are two types of seed tanks: carbon steel seed tanks and stainless steel seed tanks.

Seed tanks are also called strain culture tanks. Spawn expansion tanks are tanks for cultivating strains (microorganisms) for fermentation, that is, microbial expansion tanks. Stainless steel seed jars are suitable for yogurt, lactic acid bacteria beverages, brewing, pharmaceuticals, chemicals and bacterial culture. Common strains cultured in seed tanks include the production of monosodium glutamate, citric acid, enzyme preparations, etc. The design of the seed tank should be designed according to the characteristics of the microorganisms to be cultivated and expanded. The difference between seed tanks and fermentation tanks is that seed tanks generally have a smaller volume and are equipped with a flame inoculation port. Fermentation tanks do not have an inoculation port. They are connected to the seed tank and the strains are directly input from the seed tank for fermentation.

4. Product structure and installation of seed tank

The seed tank head and tank body are generally connected by flanges, which are easy to disassemble, clean and repair. The tank is equipped with a long sight glass, and the upper head is equipped with a sight glass and a spotlight to facilitate observation of the bacterial culture. Stirring can break up the bubbles, allow air to evenly contact the solution, and allow oxygen to dissolve in the culture medium. The function of the baffle is to change the direction of the liquid flow from radial flow to axial flow, causing the liquid to stir violently and increase dissolved oxygen. The function of setting up the defoamer is to break the foam. Commonly used forms of defoamer include sawtooth type, comb type and orifice type. The hole diameter of the orifice plate type is about 10~20 mm. The length of the defoamer is approximately 0.65 times the tank diameter. The seed tank uses a jacket for heat exchange, which can maintain the temperature, heat up and cool down. The shaft seal seals the gap between the top or bottom of the tank and the shaft to prevent leakage and contamination of bacteria.

1. The overall structure of the seed tank:

A. The fixed seed tank mainly consists of a tank body and legs.

B. The inner tank and head of the seed tank are made of polished stainless steel.

C. The jacket and reinforcement of the seed tank are made of A3 board, and the insulation layer is made of glass asbestos.

D. The outer skin of the seed jar and the ground fish scale pattern are made of **304 and 1Cr18Ni9Ti materials.

E. The sealing of the agitator and lid of the seed tank is composed of mechanical seals.

F. The upper and lower connections of the seed tank cover are made of stainless steel studs, and the sealing gasket is made of XB250 non-toxic rubber.

2. Installation and debugging of seed tank:

A. Due to long-distance transportation, first check the connecting threads of the seed tank.

B. The seed tank and the agitator should be inspected for an empty test run. The agitator can only be put into production after all transmission components are operating normally.

C. After the seed tank is connected, check each joint. If there is air leakage, tighten the pipe joints and studs until there is no leakage before it can be put into normal production.

5. Uses and characteristics of seed jars

1. Purpose: The stainless steel seed tank is suitable for fermentation, brewing, condiments, pharmaceuticals, chemicals and bacterial cultivation of yogurt and lactobacillus beverage mother liquor. It can be used for heating, insulation and cooling. It is a fully enclosed and sanitary fermentation specialized equipment.

2. Characteristics: The materials of seed jars are all made of imported 304 or 316L. This equipment has the advantages of energy saving, noise reduction, corrosion resistance, high productivity, easy cleaning and operation.
