Introduction to spray drying process

Spray drying is a widely used process in the liquid process forming and drying industry. Zui is suitable for the production of powdered, granulated or lumpy solid products from solutions, emulsions, suspensions and plastic paste liquid materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet the exact standards. Spray drying is an ideal process.

The air is filtered and heated into the air distributor at the top of the dryer, and the hot air enters the drying chamber in a spiral shape evenly. The liquid is sprayed into a very fine misty liquid droplet through a high-speed centrifugal atomizer at the top of the tower body, and it can be dried into a finished product in a short time by cocurrent contact with hot air. The finished product is continuously discharged from the bottom of the drying tower and the cyclone, and the exhaust gas is vented by the fan.

The drying speed is fast, the surface area of ​​the liquid is greatly increased after atomization, and in the hot air flow, 95%-98% of the water can be evaporated instantaneously, and the drying time is only a few seconds, which 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 control is convenient. For liquids with a moisture content of 40-60% (up to 90% of special materials), it can be dried into a powder product at one time. After drying, no pulverization and screening are required, which reduces the production process and improves the purity of the product. The particle size, bulk density and moisture of the product can be adjusted within a certain range by changing the operating conditions, and the control and management are very convenient.

Heat Meters


Heat meters are one kind of meters measuring the heat consumption. In order to save the energy and decrease the environment pollution, the heat meters are more and more popular for the modern buildings. Heat meters can realize centralized heating supply. Now with the rapid technology development, the heat meters also experience a fast way of growing up. Now the government of the world starts to pay much attention to the building remolding and new buildings heat meter installation. As the new type of energy calculation, the heat meters have the advantages of higher accuracy, energy saving and easy installation.

From the functions of the different types of heat meters, there are mechanical heat meters, digital heat meter,Ultrasonic Heat Meters, M-bus Heat Meters and also wireless heat meters. Our company, Berggruen Technology Co.,Ltd never stops the steps for further higher technology research and development. We are devoted to study the new technology in the world to make better quality heat meters.
