There are various classifications of fermentation tanks, which can be divided into ventilated fermentation tanks and anaerobic fermentation tanks according to different types of aerobic demand. In addition, it can also be divided into three types based on the different stirring forms: mechanical stirring fermentation tank, compressed air bubbling fermentation tank, and forced liquid circulation stirring. Common fermentation tanks also include airlift fermentation tanks, jet impeller fermentation tanks, and external circulation fermentation tanks.
Organic fertilizer fermenter working principle for the waste (livestock and poultry manure, food waste, domestic sludge, etc.), biomass (straw and sawdust, etc.) and reflux materials in accordance with a certain proportion of mixing, so that the moisture content of the design requirements of 60-65% into the three-dimensional aerobic system, through the adjustment of raw materials, moisture, oxygen content and temperature changes, so that the material is fully aerobic fermentation and decomposition, heat released during the decomposition process can make the material itself temperature increase, the temperature can reach 95 ºC, part of the organic matter is decomposed, thus reducing the volume of the heap to achieve the reduction of waste. The heat released during the decomposition process can increase the temperature of the material itself, and the temperature can reach 95ºC, the moisture in the fermented material is evaporated with the rise of temperature, and part of the organic matter is decomposed, thus the volume of the heap is reduced, and the reduction of waste treatment is achieved. Organic fertilizer fermenter through ventilation, oxygenation, stirring and other roles to control the temperature between 65-75 ºC, to achieve the temperature of the material fermentation treatment, at this temperature, can make the heap of a large number of pathogenic bacteria and parasites in the death of the heap, and at the same time the use of deodorization system on the emission of gas bio-odor, to achieve harmless treatment of the purpose. The product after high-temperature aerobic fermentation can be used for soil improvement, landscaping, landfill cover soil, etc.
The equipment can be used to deal with organic waste such as pig manure, chicken manure, cow manure, sheep manure, mushroom slag, Chinese medicine dregs, crop straw, etc. The operation is simple and easy, and covers a small area, the work is not affected by the external temperature, its fermentation speed is fast without odor, no pollution gas generation, the harmless treatment process can be completed in a short time, compared with the traditional aerobic composting and fermentation saves a lot of time, it is the advantage of increasing the output. Our company has been using R & D, production, sales as one model, in order to allow customers to accurately find the right, cost-effective products.
Organic fertilizer fermenter has the following advantages.
1, high-temperature aerobic fermentation, the use of high-temperature biological bacteria technology, low energy consumption, low operating costs;
2, the equipment covers a small area, high degree of automation, one person control can complete the fermentation treatment process;
3, through the biological deodorization equipment to achieve gas discharge, does not produce secondary pollution;
4, the main body of the equipment is made of stainless steel special material, reduce corrosion, long life;
5, the main body insulation design, auxiliary heating to ensure the normal operation of the equipment in a low-temperature environment;
6, after treatment of domestic sludge, food waste, livestock and poultry manure for processing organic fertilizer, to achieve resource utilization.
Fermentation tank is an important biochemical production equipment, and knowledge of its working principle, classification, usage methods, and maintenance is crucial to ensure the smooth progress of the fermentation process.A fermentation tank is a device used in the microbial fermentation process, mainly for industrial microbial fermentation and cultivation. According to the nature of the fermentation materials, fermentation tanks are mainly divided into two types: solid fermentation tanks and liquid fermentation tanks. The working principle of a solid fermentation tank is that microorganisms grow in a moist and insoluble substrate for fermentation. During the solid fermentation process, there is no free water. As the amount of free water produced by microorganisms increases, the range of solid fermentation extends to viscous fermentation and solid 2. The liquid fermentation tank, on the other hand, utilizes mechanical stirring to generate axial and radial flow, allowing the materials in the tank to mix well and the solid substances in the liquid to remain suspended, which is conducive to full contact between solids and nutrients and facilitates nutrient absorption
When using a fermentation tank, a series of operation steps and maintenance measures need to be carried out. For example, before use, it is necessary to calibrate the pH electrode and dissolved oxygen electrode, sterilize the tank, and ensure that the cooling water and air pump are working properly. During the operation process, it is also necessary to pay attention to safety operating procedures, such as ensuring that all individual equipment can operate normally when using this system, and that the steam pressure flowing through the air filter during disinfection should not exceed 0.17MPa.
Material of the fermentation tank is usually SUS304/316L high-grade stainless steel, and the inner and outer walls are polished to ensure safety, hygiene, and no dead corners.

The main differences between bacterial and cellular fermenters are their design purpose, the type of microorganisms used, and the operating conditions.
Design Purpose and Scope of Application:
Bacterial fermenters are mainly used to culture various bacteria, especially for microbial fermentation under anaerobic conditions. These tanks are usually well sealed to prevent contamination of the bacteria and are equipped with stirring devices to facilitate the fermentation process.
Cellular fermenters, on the other hand, are more commonly used for the cultivation of advanced cells such as plants, worms and mammals, which usually require more sophisticated environmental controls and longer growth cycles7.
Types of microorganisms used:
Bacterial fermenters are mainly used to culture single or multi-cellular bacteria such as E. coli.
Cellular fermenters, on the other hand, are used to culture more complex cells, such as plant and animal cells, which may be involved in more advanced biotechnology and biopharmaceutical industry needs.
Operating conditions:
Bacterial fermentation is usually carried out under anaerobic conditions without oxygen, which helps to maintain bacterial activity and proliferation.
Cellular fermentation, on the other hand, may require different environmental conditions, such as specific temperatures, pH levels, and nutrient availability, which are designed to support cell growth and metabolic activity.
To summarize, although both bacterial and cellular fermenters are a type of bioreactor, they differ significantly in their design, the types of microorganisms used, and the operating conditions. Bacterial fermenters are more focused on the rapid multiplication of microorganisms and production of products, whereas cellular fermenters are more concerned with the cultivation of advanced cells and the production of biologics.
