LPG High Speed Centrifugal Spray Dryer Product Introduction
LPG high-speed centrifugal spray dryer is a kind of dedicated equipment for drying suspension, emulsion, paste and solution. This spray drying machine is particularly prominent in drying resins, polymers, dyes, pigments, glass, rust remover, ceramics, pesticides, carbohydrate, detergents, fertilizer, dairy products, organic compounds and inorganic compound liquids.
Fishmeal spray dryer machine Working principle
Air is filtered and heated into the air distributor at the top of the dryer. The hot air spirally enters the drying chamber. The feed solution is passed through the high-speed centrifugal atomizer at the top of the tower body, and (rotated) is sprayed into very fine mist-like liquid beads, which can be dried in a short time in the cocurrent 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 exhausted by the fan.
Fishmeal spray dryer equipment Performance characteristics
Drying speed is fast, the surface area of material liquid is greatly increased after atomization. In the hot air current, 95%-98% of water can be evaporated instantaneously, and the drying time is only a few seconds. It is especially suitable for the drying of heat-sensitive materials.
The product has good uniformity, fluidity and solubility, and the product has high purity and good quality.
The production process is simplified and the operation and control are convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials), the liquid can be dried once into a powdered product, without crushing and screening after drying, which reduces production processes and improves product purity. The product particle size, bulk density and moisture content can be adjusted within a certain range by changing the operating conditions, and the control and management are very convenient.

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