How Does The Organic Fertilizer Machine Dry The Fertilizer

Organic fertilizer mainly comes from plants and animals.It is a carbon material applied to soil to provide plant nutrition as its main function.Through the processing of biological substances, animal and plant wastes and plant residues, the toxic and harmful substances are eliminated, which are rich in a large number of beneficial substances, including a variety of organic acids, peptides and rich nutrients including nitrogen, phosphorus and potassium.It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect.It can increase and renew soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, which is the main nutrient for green food production.Organic fertilizer contains a lot of water, which is not convenient for direct storage, transportation and use, so it needs to be dried in the production process of organic fertilizer.The drying process is an important part of the fertilizer production line it is very important to pay attention to the drying method.The fertilizer produced by the organic fertilizer machine is completely dry fertilizer.Organic fertilizer raw materials need to be dehydrated and dried in the production of organic fertilizer, so there are several drying methods, how does the organic fertilizer machine produce dry fertilizer? organic fertilizer raw materials need to be dehydrated and dried in the production of organic fertilizer.There are several drying methods.Here are three methods to summarize.(1) mechanical dehydration method: mechanical dehydration method is to extrude part of water by pressurizing materials.The common methods are pressing, settling, filtering and centrifuging.Mechanical dehydration can only remove part of the free moisture in the material, and the combined moisture is still left in the material.Therefore, the moisture content of the material after mechanical dehydration is still very high, generally 40-60%.But mechanical dehydration is the most economical method.(2) second, the organic fertilizer dryer heating drying method: this is what we often call the rotary dryer drying method.It uses heat energy to enter the dryer cylinder, and the temperature in the cylinder reaches about 150 degrees.According to different materials, the temperature can be adjusted to gasify the water in the materials, and to remove the water in the materials requires a certain amount of heat energy.This method usually uses air to dry the material.The air is heated in advance and sent to the dryer, which transfers the heat to the material, vaporizes the moisture in the material, forms the water vapor, and brings it out of the dryer with the air.After heating and drying, the material can remove the combined moisture in the material and reach the moisture content required by the product or raw material.This method can be applied to many industries, and it is also one of the simplest methods to meet the requirements.(3) chemical dehumidification method: it is to 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 a small amount of moisture in materials.Therefore, it is rarely used in the organic fertilizer production.
