Solid state fermentation tank is an important biotechnology equipment used for producing sustainable renewable energy sources such as bio fertilizers and biomass energy. Proper operation of solid fermentation can effectively ensure the normal operation of equipment, extend its service life, and ensure production safety and product quality. Today, the editor will take you to understand the operating procedures of solid fermentation tanks.
1. Equipment inspection
Before each use, the solid fermentation tank must be inspected to ensure proper operation of the equipment
(1) Check sterilization status
Check the material of the fermentation tank for oxidation, rust, deformation, and other issues;
Confirm that the steam outlet and exhaust outlet are correctly connected;
Check if the air inlet and outlet are blocked;
Check if the automatic control system is functioning properly.
(2) Check the feeding system
• Determine whether the quality and moisture content of the raw materials meet the fermentation conditions;
Clean the dust, slag, and residual impurities in the feeding system.
2. Workflow
(1) Accept raw materials
Transport the raw materials to the silo;
Use a conveyor belt or elevator to transport raw materials directly to the fermentation tank;
Add water quantitatively.
(2) Solid state fermentation
Utilize equipment budget to determine the optimal production process parameters;
Maintain the temperature, humidity, and ventilation of the fermentation tank to achieve optimal growth of the microbial community;
Adjust the growth rate of the microbial community, optimize the production of biological products and products;
Monitor temperature and acidity during the production process.
(3) Sampling and Measurement
Sampling and testing are conducted daily or at regular intervals, and the testing frequency can be adjusted according to production needs;
• Select representative samples;
Clean the tank mouth, disinfect the equipment with disinfectant, and dispose of any residual disinfection of the tank mouth before sampling.
(4) Harvesting process
Use an elevator to harvest fermented biofertilizers and biomass energy;
During the harvesting process, pay attention to controlling the glossiness, width, and sealing of the inlet;
• Collection and recording of important parameters.
