Tongda Heavy Industry Organic Fertilizer High Temperature Fermentation Production Equipment Vertical Fermentation Tank Sludge Fermentation Equipment

Tongda heavy industry organic fertilizer fermentation tank can be used to process organic waste such as pig manure, chicken manure, cow manure, sheep manure, mushroom residue, Chinese medicine residue, crop straw, etc. Only covers an area of ​​10-30 square meters), closed fermentation, killing eggs of diseases and insects (can be adjusted to 80-100 ℃ high temperature), it is the best choice for the majority of breeding enterprises, circular agriculture, and ecological agriculture to realize the utilization of waste resources .

working principle:

Fermentation tank refers to a device used in industry for microbial fermentation. Its main body is generally a main cylinder made of stainless steel plate, and its volume is from 1 cubic meter to hundreds of cubic meters. In the design and processing, attention should be paid to the strict and reasonable structure. Steam sterilizable, flexible in operation, internal accessories to minimize production and reduce energy consumption.


1.Calibrate pH electrode and dissolved oxygen electrode.

2.Tank sterilization. Put the culture medium into the tank as needed and seal it as required, the small fermenter (5L) can be put into a large sterilizer for sterilization (115℃, 30 minutes); the large fermenter (10L and above) Sterilize with steam (121°C, 30min).

3.After the tank is cooled, place it on the fermentation stand and install it well; turn on the cooling water, turn on the power of the air pump, connect the ventilation pipe to start ventilation, adjust the air intake knob to make the ventilation volume appropriate, and keep the tank pressure at 0.05MPa; Set the temperature, pH, stirring speed, etc., and calibrate the slope of the dissolved oxygen electrode to 99% under the determined rotation speed and ventilation rate.

4.After the temperature is stable and the parameters are correct, connect the seeds, start the fermentation timing, and start recording various parameters.

5.After the fermentation, clean the tank and the electrode, insert the pH electrode into the triangular flask with 3M potassium chloride for later use, and cover the probe of the dissolved oxygen electrode with a protective sleeve and save it for future use.
