Biological organic fertilizer production process - pre-treatment stage

The biological organic fertilizer production process mainly includes three main stages: pre-treatment, primary fermentation and post-treatment. Today, Huaqiang Heavy Industry will briefly introduce the pre-treatment stage.

Biological organic fertilizer production process - raw material selection and pre-treatment: raw materials can be organic waste such as agricultural waste (such as straw), urban domestic waste, livestock and poultry manure, food processing waste, etc. The selection of raw materials needs to consider factors such as their moisture content, carbon-nitrogen ratio (C/N ratio), and biochemical degradability. Pretreatment includes debris removal, crushing, and adjusting moisture and C/N ratio. The particle size of the crushed raw materials should be appropriate, generally controlled at 12 to 60 mm, so that microorganisms can reproduce and ferment better. Adjust the moisture to a suitable range, usually 55% to 65%, which can be judged by holding the material tightly in your hand to form a ball, and water marks appear but do not drip out.
 

Biological organic fertilizer production process - mixing and batching: Mix the pre-treated raw materials with organic biological fermentation compound bacteria (1-2 kg per ton of raw materials) in proportion. When mixing ingredients, you need to dissolve brown sugar in water first, then add organic fertilizer fermentation bacteria and stir thoroughly, then sprinkle the diluent evenly on the raw materials, and stir thoroughly with a mixer. Adjust the C/N ratio of the raw materials to an appropriate range, generally 20:1 to 30:1, to ensure the smooth progress of the fermentation process.

The above is the pre-treatment stage of the biological organic fertilizer production process. If you want to know more about the organic fertilizer production process, please contact Huaqiang Heavy Industry.
