Large-scale soy products factories use okara resources to vigorously build biogas and feed, but still have a large amount of okara waste discarded. The effective nutrients of okara are lost for no reason, the utilization rate is low, and secondary pollution is formed. The use of bean dregs to prepare organic fertilizers, on the basis of prolonging the utilization chain of resources, makes it profitable.
The traditional cultivation fertilizer is mainly composed of fertilizer, chicken and duck manure. With the rapid increase of demand for organic fertilizer in the market, the resources such as fertilizer are increasingly tense, and the cultivation cost is rising rapidly. Because the growth rate of resources is far lower than the growth rate of fertilizer and fertilizer needed for cultivation, the price of organic fertilizer rises in a straight line, which leads to a sharp decline in cultivation efficiency, and the smooth development of melon and fruit production is restricted due to the shortage of raw materials. Organic fertilizer is an important resource for agricultural production. Investment in organic fertilizer production equipment is the choice of many farms and industries.
Okara waste can't be used as fertilizer directly and need to be processed later. Because fresh soybean dregs will not only burn the roots of plants, but also attract a large number of flies and mosquitoes, which is not conducive to plant growth. Soybean dregs can be used as fertilizer only after they are fermented and dried. If you want to ferment quickly, you can add some bacteria in physics.
Okara's nutrient content and organic content are high, but the material is finely crushed. Composting alone has serious problems of poor ventilation in the matrix, long germination time, and high bacterial pollution rate. It indicates that the utilization of soybean dregs cannot be fermented with a single raw material, and it needs to be combined with a corresponding proportion of straw and manure to be used as an organic fertilizer. In the production of organic fertilizers, the nutritional components of the final fertilizer products are mainly formulated according to different fruits, especially growth needs.
In the production process of organic fertilizers, nutrients with different ratios can be added to them through an organic fertilizer granulator to make granular fertilizers. Of course, according to the different fermentation raw materials and different products, choose different granulators, such as flat die pellet mill, disc granulator machine, rotary drum granulator, etc.
