Organic fertilizer fermentation tank equipment each part of the structure description

Organic fertilizer fermentation tanks each part of the structure description. Because the fermentation tank is the processing process, most biological reaction systems need to cool during operation, and the medium after local sterilization requires quick cooling. For large -scale fermentation tanks, fermentation tanks usually use cooling disk tubes installed in the tank or using clip -type fermented tanks for temperature control. For small fermentation tanks, the heat exchangers are mostly used as a heat exchange device. During the four -stage unit time, the amount of cold is C. Generally, the calculation of the cooling amount and cooling area are subject to 72h. Refrigeration mainly includes ammonia and ethanol water. Although the direct evaporation of ammonia is commonly used in organic fertilizer fermentation tanks abroad, it has the advantages of reducing low energy consumption operation costs, but due to its difficulty in manufacturing inspection and corresponding control levels, only a few funds in China are adopted in China. Most of the manufacturers still choose to be a refrigerant from 3 to 4 ° C. Ethanol water. Due to less hypoglycemic during the cooling process, the air bubble motion generated by C02 reduces the thermal conduction coefficient. For large diameter tanks, especially in diameter, or more than 300m3, the cooling of ethanol water as refrigerant has increased. In order to achieve the corresponding higher thermal conductivity coefficient, the refrigerant flow rate must be increased, so energy consumption is increased, so it should not be adopted for large good oxygen organic fertilizer fermentation tanks with ethanol water as a refrigerant.

When the sterilization of organic fertilizer fermentation tanks is performed, the exhaust in the tank needs to be unobstructed. However, the exhaust volume of each exhaust hole cannot be too large, and all rational use to save the amount of gas consumption. When the pressure inside the organic fertilizer fermentation tank is lower than the air pressure, enter the sterile air directly into the organic fertilizer fermentation tank. It can achieve thorough disinfection and sterilization. Organic fertilizer fermentation tanks are strictly prohibited to produce negative pressure in organic fertilizer fermentation tanks during the cooling process of empty disappearance and real disappearance, so as not to cause pollution and even damage the equipment. During each operation The tank pressure of the fermentation tank, otherwise it will cause liquid flow in the organic fertilizer fermentation tank into the filter. Cover the filter element or make the filter fail. Do not forcibly disassemble or repair organic fertilizer fermentation tanks.

The impact of organic fertilizer fermentation tank temperature on the fermentation process is multi -faceted. It will affect the rate of various enzyme reactions, change the synthesis direction of the bacteria metabolic products, and affect the metabolic regulation mechanism of microorganisms. In addition to these direct impacts, the temperature also affects the physical and chemical properties of the fermentation liquid, such as the viscosity, matrix and oxygen’s solubility and transmission rate in the fermentation solution, the decomposition and absorption rate of certain matrix, which will then affect the fermentation of fermentation Biological synthesis of dynamic characteristics and products. The fermentation temperature of organic fertilizer fermentation tank is suitable for both the growth of the bacteria and the temperature of the synthesis of metabolic products. It changes with the different periods of the bacteria, the cultivation base, the cultivation conditions, and the growth stage of the bacteria. Theoretically, only one cultivation temperature should not be selected during the entire fermentation process, but different cultivation temperature should be selected according to different stages of fermentation. In the growth stage, the appropriate growth temperature should be selected. During the product secretion stage, the suitable production temperature should be selected.

The fermentation tank is strong. From Newtonian fluids to non -Newtonian filamentous bacteria fermentation liquids, they can provide high quality transmission rates and necessary mixed speeds according to the actual conditions and needs. The disadvantage is that the driver of the mechanical mixer is high, generally (2-4) KW/M3, which is a huge burden on a large reactor. Fermentation tanks and technology play a particularly important role in the development of pharmaceuticals and biological products. Among many types of fermentation equipment, standard fermentation tanks with both ventilation and mechanical stirring are commonly used in various fields such as antibiotics, amino acids, and citric acid.

In recent years, various types of advanced stainless steel organic fertilizer fermentation tanks have been installed with magnetic coupling mixers, which uses magnetic puppets to make the tank have no direct axis connection to further reduce the pollution rate. Organic fertilizer fermentation tanks use DC motors, which can achieve a variable change. This is particularly important for the cultivation of animal cells. Slowly stopping reduces the damage to cells. For some larger stainless steel organic fertilizer fermentation tank systems, due to the power needs, more frequency conversion AC motor controls speed, and the speed of bacterial wall tanks is large.
