Performance characteristics and ideal process of spray drying equipment
Dec 19, 2018

The spray drying equipment is a kind of continuous atmospheric pressure dryer when it is used. When the operation is carried out, the liquid is sprayed into a mist by special equipment, so that it can be dried in contact with hot air, and can be used during use. It is used directly to dry some heat-sensitive liquids, suspensions and viscous liquids such as milk, eggs, tannins and medicines. Also used for drying fuels, intermediates, soap powders and inorganic salts.


spray drying equipments are the most widely used process in the liquid process forming and drying industry and are best suited for the production of powdered, granular solid products from solutions, emulsions, suspensions and paste liquids. 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 exact standards.


spray drying equipment performance characteristics

1. The spray drying equipment has a fast drying speed, and the surface area of the liquid is greatly increased after atomization. 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 heat sensitivity. Drying of the material.

2. The product has good uniformity, fluidity and solubility, and the product has high purity and good quality.

3. 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 powdered products at one time, which is convenient for control and management.
