Pesticide special dryer (Zhejiang Xinhecheng Co., Ltd.)
Application client：Zhejiang Xinhecheng Co., Ltd.Selected products：：Centrifugal spray dryer
Materiel:： Pesticide
Detailed description
principle:
After filtering and heating, the air enters the air distributor at the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The feed liquid is sprayed into a very fine mist-like liquid bead by the high-speed centrifugal atomizer (rotation) at the top of the tower body, and it is in parallel flow contact with hot air, and can be dried into a finished product in a very short time. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is evacuated by the fan.
Features:
● The drying speed is fast, the surface area of the material liquid is greatly increased after being atomized. In the hot air flow, 95% -98% of water can be evaporated in an instant, and the drying time is only a few seconds, which is especially suitable for heat-sensitive materials. dry.
● The product has good uniformity, fluidity and solubility, high purity and good quality.
● Simplified production process and convenient operation and control. For liquids with a moisture content of 40-60% (special materials up to 90%) can be dried into powder products at a time, without crushing and screening after drying, reducing the production process and improving product purity. The product particle size, bulk density, and moisture can be adjusted within a certain range by changing the operating conditions, which is convenient for control and management.
