Most bioorganic fertilizers are made of decomposed organic materials as the base material, adding microbial agents, and then mixing with chemical fertilizers. Bio organic fertilizer mainly has two dosage forms: powder and granule. Therefore, the biofertilizer production process for microbial adding includes powder functional bacteria and granule functional bacteria. Microbes in the process of biological fertilizer production should pay attention to during the process of adding control of temperature, moisture, organic matter.
Powder functional bacteria addition process
According to certain formula, will crush after fermentation of organic materials mixed with humus powder. Then you add a certain amount of functional bacteria agent distribution, repackaging, after drying can be made into products. You can use equipment such as dynamic feeders and mixers to complete the powder function.
Granular biofunctional inoculant addition process
In the production of biological organic fertilizer granules, add fertilizer functional bacteria technology, according to the functional bacteria added time is divided into the following three:
Add before granulation
Organic materials and functional bacteria agent according to certain formula mixed, and then sent to the granulator granulation. Granulation of the biological fertilizer after drying, cooling, screening, packaging, will be able to become a finished product.
Add in the granulation process
Add a certain amount of humic acid powder into the organic material powder and stir evenly through a horizontal mixer. And then sent to the granulator granulation, in the process of adding microbial agents. Therefore, you’d better choose a granulation equipment with a spray device, such as a drum granulator, a disk granulator. After drying, in order to maintain the activity of the biological bacteria agent, it is necessary to cool down in time to ensure the quality of the microbial fertilizer.
Add after granulation
In granulation and qualified in accordance with the ratio of biological fertilizer spraying function of a certain amount of liquid agent. In order to remove moisture and retain the activity of bacteria agent, it needs to go through low temperature drying and screening. Then use a single or double bucket automatic packing scale to complete the final stage of microorganism fertilizer production.
Temperature control:
Temperature is one of the important factors restricting the growth of microorganisms. Commonly used functional bacteria are generally suitable for growth temperature of 20-40℃, not high temperature. The higher the temperature, the faster the microbial death rate. Therefore, biofertilizer production process for microbial adding requires that the carrier temperature should be below 50 ° C after the addition of functional bacteria.
Organic control:
Organic matter contained in organic materials is the living environment of functional bacteria and the nutrient source required for production. In order to ensure the normal growth and reproduction of functional bacteria, the organic matter content of the total material should be more than 30%, preferably 50%-70%; C/N is (30-35) : 1, which reaches (15-20) : 1 after decomposition.
