Low temperature spray drying freeze granulator
Low temperature spray drying freeze granulator is the most widely used process in liquid forming and drying industry. It is most suitable for generating powder, granular or massive solid products from solutions, lotion, suspensions and plastic paste liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product must meet precise standards. Low temperature spray drying freeze granulator is a very ideal process.
Product Overview:
Low temperature spray drying freeze granulation machine is the most widely used process in liquid process forming and drying granulation industry. It is most suitable for generating powder, granular or massive solid products from solutions, lotion, suspensions and plastic paste liquid raw materials.
Working principle:
After being filtered and heated, the air of the low-temperature spray drying freeze granulator enters the air distributor on the top of the drying granulator, and the hot air enters the drying chamber in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer or high-pressure spray gun on the top of the tower body, rotates the spray to form a very fine mist or small liquid bead, and can be dried and cooled into finished products in a very short time when it is in parallel flow contact with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan.
Product features:
The low-temperature spray drying freeze granulator produced by Changzhou Yuntai Drying has a fast drying and cooling speed, and the surface area of the liquid material is greatly increased after atomization or high-pressure spray gun. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds. It is especially suitable for drying heat sensitive materials.
The products of the low-temperature spray drying freeze granulator have good uniformity, fluidity and solubility, high purity and good quality. The production process is simplified and the operation control is convenient. For special materials with a moisture content of 40-60%, liquids with a moisture content of up to 90% can be dried into powder products in one go, without the need for crushing and screening after drying, reducing production processes and improving product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing the operating conditions, making control and management very convenient.
