Organic Fertilizer Drying Process

Drying link is an important link in the fertilizer manufacturing process, and the drying method is very key. The fertilizer produced by the organic fertilizer equipment is completely dry fertilizer, so how does the organic fertilizer equipment produce dry fertilizer?

(1) Mechanical dewatering method: mechanical dewatering method is to extrude part of the water by pressurizing the material. Common methods include pressing, sedimentation, filtration and centrifugal separation. 

Mechanical dehydration can only remove part of the free water in the material, while the combined water remains in the material. Therefore, the water content of the material after mechanical dehydration is still very high, generally 40-60%. But mechanical dehydration is an economical method.

(2) Heating and drying method: also known as drying, it uses heat energy to heat materials and evaporate the water in materials. A certain amount of heat is required to remove moisture from the material.

 Generally, air is used to dry materials. The air is preheated and sent to the dryer to transfer heat to the material, so that the water in the material evaporates to form water vapor, which is brought out of the dryer with the air. After the material is heated and dried, the combined water in the material can be removed to achieve the water content required by the product or raw material.

(3) Chemical dehumidification method: use hygroscopic agent to remove a small amount of moisture in gas, liquid and solid materials. 

Due to the limited dehumidification capacity of hygroscopic agent, it is only used to remove trace moisture in materials. Therefore, it is rarely used in production.

Quality Fertilizer Production Tips

The effect of fertilizer produced by fertilizer plant equipment from sx  and fertilizer manufacturing technology is remarkable. In agriculture, various raw materials can be used to produce organic fertilizer or compound fertilizer, and various fertilizer production lines are designed to produce fertilizer.

Chicken manure, pig manure, cow manure, sludge, straw, plant ash and other wastes as raw materials, due to the complexity of various raw materials, the nutrient content is different. The faeces of various animals are also different. For example, when using crop straw as the main raw material for fermentation, about 20% of animal manure can be added; when using animal manure as the main raw material, about 20% of manure can be added. The fermentation method is the same as above. If the raw material with high acidity is used for fermentation, 1-3% lime powder should be added to adjust the pH. This method is suitable for all kinds of crops and soil, which can be used by themselves or processed into commercial fertilizer for sale.

Organic fertilizer production line

In the process of fertilizer manufacturing, when producing organic fertilizer, fertilizer equipment is equipped with different types and series. We can choose the right fertilizer machine to produce fertilizer granulator.

The fermented organic fertilizer was used as carrier. Bio organic fertilizer made by adding probiotics is a kind of specific organic fertilizer, which contains fermentation microorganisms beneficial to crop growth and has the function of microbial fertilizer. This fertilizer is easy to make. For example, 1000 kg of dry based organic fertilizer is used after fermentation, 1.5% - 15% probiotics are added, fully mixed, turned and mixed, and then processed into biological fertilizer. Organic fertilizer with bacterial content ≥ 200 million to ≥ 200 million / g.

Bio organic fertilizer produced by bio fertilizer production line is a kind of complete fertilizer rich in organic matter. It contains not only nitrogen, phosphorus, potassium and other elements, but also trace elements such as calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum and chlorine. The functional bacteria in bio organic fertilizer can not only decompose the mineral phosphorus in the soil, but also decompose the mineral potassium in the soil, releasing a variety of nutrients, which can provide sustainable nutrition for crops. From the application effect of many years, the effect of bio organic fertilizer has achieved remarkable results in various crops.
