Changzhou Baokang Drying Equipment Co., Ltd. is a key enterprise in China's drying industry, specializing in the production of drying equipment, granulation equipment, chemical machinery, pharmaceutical machinery, food machinery. The following Baokang company will explain the three drying methods of the drying equipment :
(1) Mechanical dehydration method The mechanical dehydration method is a method in which the water is discharged by means of pressurizing the material. Commonly used for crushing, settlement, filtration, or centrifugation. The mechanical dehydration method can only remove part of the free moisture in the material, and the combined water remains in the material. Therefore, the moisture content of the material after mechanical dewatering is still very high, usually 40 to 60%. But the mechanical dehydration method is the economic method of Zui.
(2) The heating and drying method is also the dryness we often say. It uses the moisture in the material of the thermal heating material to vaporize. The water needs to consume a certain amount of energy to remove the material. Air is typically used to dry the material preheated air into the dryer, and heat is transferred to the material vaporized material in the water to form water vapor, with dry air. After the heated material is dried, the bonding material can be removed in water to achieve the desired moisture content of the product or material.
(3) Chemical dehumidification The moisture absorbent is removed by using a gas, a liquid, and a small amount of water in a solid material, and only a small amount of water is removed from the material due to the limited capacity of the moisture absorbent. Therefore it is rarely used for production.
In the actual production process, for high-humidity materials, a large amount of free moisture is generally removed by mechanical dehydration as much as possible, and then other drying methods are used for drying.
