How to Ensure The Biofertilizer Production Project Design

Content

Formulation of biofertilizer formula

You should design the nutrient ratio of N, p, k or medium and trace elements and the total nutrient content range (generally in the range of 6%-25%) according to the bio fertilizer characteristics of different crops. Functional microorganisms and organic matter play an important role in nutrient efficiency, promoting growth and yield, enhancing resistance, improving soil and protecting environment. Therefore, under the premise of ensuring increased production, the biofertilizer production project design should consider the functional characteristics and effective viable bacteria number of selected strains according to the needs of fertilizer nutrient formulas.

Strengthen dilution function

From the perspective of production needs, powders and granules are generally used as base fertilizers, and have good slow-release function. In order to play a greater fertilizer effect of biofertilizer, you should adjust functional bacteria, organic materials and fertilizer raw materials and their proportions according to factors such as crop fertilizer requirements, soil characteristics, precipitation. This is conducive to the production of nutrient release and crop nutrient absorption rules in line with the microbial fertilizer. Such ability can effectively improve nutrient utilization.

Optimize the process route

In the biofertilizer production project design, optimizing the production process is the key to ensure the product quality. At present, the production of biofertilizers mainly has three process routes: liquid, powder and granule production. You should optimize the appropriate production process route according to the characteristics of strain fermentation and product dosage form.

Liquid production

Liquid production process is simple and easy, high production efficiency, high degree of automation, controllable quality. The main equipment is: fermenter, air filtration equipment, thermal power equipment and so on. The fermented liquid fermentation tank after the inspection, according to the nutrient formula to add a certain amount of water soluble inorganic nutrients. Then, you will get the liquid biological fertilizer.

Powder production

Powder biofertilizer product process equipment is simple, small investment. Organic waste fermentation can be outdoors or in fermentation tank, request to control temperature and ventilation. This can be achieved by heating units and tipping machines. After solid fermentation, after grinding, low temperature drying, you can mix a certain amount of biological bacteria according to the ratio of nutrients, and then quantitative packaging, you can make powder bio fertilizer.

Granules production

Granules production process is on the basis of the powdery production process, add the granulation process. After the completion of granulation drying cooling, and then by automatic packaging weighing quantitative packaging. The main equipment has an additional granulator, therefore, the cost has also increased.

Adding method of bactericide

Maintaining the activity of functional microorganisms is a noteworthy point in the biofertilizer production project design. Granular biological fertilizer should go through the high temperature granulation process. And there are three ways to add bacteria: adding before granulation, adding during granulation, and spraying after granulation.

Coating machine for better biofertilizer granules making

The first two kinds of functional bacteria are affected by high temperature, and the mortality rate is higher. The survival rate is less than 70%. Generally, spraying after granulation has a high survival rate. But in order to prevent the loss of bacterial agent nutrients, you can use a coating machine for coating.
