Urine formaldehyde resin centrifugal spray dryer

Urine formaldehyde resin centrifugal spray dryer

working principle

The urea formaldehyde resin centrifugal spray dryer is an air distributor on the top of the centrifugal spray dryer through the filter and heater, and the hot air enters the dryer in a spiral form. The material liquid is pumped from the material liquid tank to the centrifugal atomizer at the top of the dryer through a filter, causing the material liquid to spray into extremely small mist droplets. The material liquid and hot air come into contact in parallel, and the moisture evaporates rapidly, drying into finished products in a very short time. The finished products are discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan. Users can choose the heating method, dust collection method, and dust removal method according to their actual situation.

Core Features

Efficient and fast: Hot air and mist droplets come into contact with each other, resulting in high water evaporation efficiency, making it suitable for heat sensitive materials. ‌

Particle size controllable: By adjusting the speed, the product particle size can be precisely controlled, and the processing capacity allows for a fluctuation of ± 25%. ‌

Complex structure: it is necessary to ensure that the diameter of the spray chamber matches the rotating speed of the spray plate (the tower diameter must be greater than the range of spray torque), and the spray plate needs to undergo dynamic balance test. ‌

Scope of application: Suitable for fields such as food, pharmaceuticals, and chemical engineering, capable of handling high viscosity liquids (≤ 5000 mPa · s) and materials with a solid content of up to 70%.

Technical Specifications

Note: The evaporation rate of water is related to the characteristics of the material and the temperature of the hot air inlet and outlet. When the outlet temperature is 90C, the water evaporation curve is shown in the above figure (for selection reference). As the product is constantly updated, relevant parameters may change without prior notice.
