The process description of organic fertilizer production equipment can be divided into the following stages in detail, each of which involves specific equipment and operation processes:
1. Pretreatment stage
Purpose: To preliminarily crush and mix organic waste for subsequent fermentation and processing.
Main equipment:
Crusher: Used to crush organic waste such as livestock and poultry manure, agricultural waste, etc. into smaller particles for fermentation and decomposition by microorganisms.
Mixer: Mix the crushed materials with appropriate amounts of water, auxiliary materials, etc. to provide suitable conditions for subsequent fermentation.
2. Fermentation stage
Purpose: Under the action of microorganisms, the organic matter in the organic waste is gradually decomposed into organic fertilizer.
Main equipment:
Fermentation tank: Provide suitable temperature, humidity and ventilation conditions for the fermentation process. The fermentation tank is usually equipped with a stirring device to promote uniform fermentation of the material.
Compost turning machine: Used to regularly turn the material during the fermentation process to increase the contact area between the material and the air and improve the fermentation efficiency.
Fermentation process:
Organic waste is fermented in the fermentation tank for a period of time, the temperature gradually rises, and the organic matter is decomposed by microorganisms into stable organic fertilizer.
The fermentation time is generally between one week and several weeks, depending on the type of material, temperature, humidity and other conditions.
3. Drying stage
Purpose: To remove excess moisture from the fermented organic fertilizer for subsequent granulation and packaging.
Main equipment:
Dryer: Such as rotary dryer, belt dryer, etc., using hot air or hot flue gas to exchange heat with the material to remove moisture from the material.
