Biological organic fertilizer production process - primary fermentation stage

Since biological organic fertilizer is rich in nutrients and organic matter required by various crops, it is very popular in the market, so many people are very interested in the production process of biological organic fertilizer. The production process of biological organic fertilizer mainly includes three main stages: pretreatment, primary fermentation and post-treatment. Today, Huaqiang Heavy Industry will briefly introduce the primary fermentation stage.

Biological organic fertilizer production process - composting fermentation: The mixed raw materials are sent to the primary fermentation workshop and piled into a fermentation pile. The aerobic fermentation process is adopted, and the materials are turned by the turning machine to make the air, moisture and microorganisms evenly distributed in the pile. The fermentation temperature is controlled at 50℃～65℃ for aerobic fermentation. The pile needs to be turned regularly during the fermentation process, generally once every 2 days, and water and nutrients are added. The fermentation cycle depends on the raw materials and process conditions, generally ranging from 8 to 20 days.
 

Biological organic fertilizer production process - temperature and humidity control: During the fermentation process, the changes in temperature and humidity need to be closely monitored to ensure the stability of the fermentation process. When the pile temperature rises above 60℃, it needs to be maintained for a period of time (such as 48 hours) to kill pathogens, insect eggs and grass seeds. If the pile temperature is too high (over 70℃), the pile needs to be turned immediately to lower the temperature.

The above is an introduction to the primary fermentation stage of the biological organic fertilizer production process. If you are interested in this organic fertilizer production line and fertilizer production equipment, please contact Huaqiang Heavy Industry.
