High-speed Centrifugal Spray Dryer Suitable For Liquid Processes

Description:

Spray drying is the most widely used process in liquid processing and drying industries. It is best suited for producing powdered or granular solid products from solutions, emulsions, suspensions, and pastes. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product must meet precise standards.

Air is filtered and heated before entering the air distributor at the top of the dryer. The hot air enters the drying chamber evenly in a spiral pattern. The liquid feed is atomized into extremely fine mist droplets by a high-speed centrifugal atomizer (rotating) at the top of the tower, which come into contact with the hot air in parallel flow, drying the product into the finished product in a very short time. The finished product is continuously discharged from the bottom of the dryer and the cyclone separator, while the exhaust gas is vented by a fan.

Application:

It is a widely used equipment for forming and drying liquid materials. It is particularly suitable for processing liquid raw materials such as solutions, emulsions, suspensions, and pastes into powdered or granular solid products in one step, achieving one-step powdering. It is one of the most widely used spray drying processes in industry today.

Specification:

Feature Advantage:

1.The drying speed is rapid. After atomization, the surface area of ​​the liquid material is greatly increased, and 95-98% of the moisture can be evaporated instantly in the hot air stream, completing the drying process in just a few seconds. It is particularly suitable for drying heat-sensitive materials.

2. The product has good uniformity, flowability, and solubility; it is high in purity and of good quality.

3. The production process is simplified, and operation and control are convenient. Liquids with a moisture content of 40-60% up to 90% for special materials can be dried into powder products in one step. No crushing or screening is required after drying, reducing production steps 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.
