High-speed centrifugal spray dryer
分享:

Overview:
High-speed centrifugal spray drying is the use of the raw material liquid atomizer droplet dispersion is, and dried with hot air to obtain the product of a droplet drying method. Feed solution can be solution, suspension, or a liquid or cream melting liquid paste. Dry products can be made as needed powder, granular, hollow spheres or pellets.

Working principle:
Air is filtered and heated, the air distributor into the dryer at the top, spiral hot air evenly into the drying chamber, liquid through the top of the tower high-speed, high-speed centrifugal atomizer, (rotation) spray into extremely fine mist liquid beads, and hot air exposure in a very short period of time can be dry for the finished product. Product continuously from the bottom of the drying tower and cyclones in the output, exhaust from the fan discharge.

Performance Introduction:
Atomizer core components: high-precision bearings used in all (Sweden SKF bearings),
no-load vibration ≤ 5μM load vibration ≤ 15μM
Trouble-free operation: up to 7,000 hours or more.
Atomizer total feeding quantity :5-15000kg / h.
Electrical control system: different levels, sub-scale, various control programs to meet different needs; classical logic approach; dynamic process simulation system; FX-DU/WIN-C special software programming; PLC control; configuration control; man-machine interface touch screen operation control.
Pharmaceutical drying machine can be added: shaking, sweeping gas, the cooling jacket and other equipment, piping all in compliance with GMP requirements.

Features:
A. Fast drying, after the spraying of liquid surface area increased significantly, in the hot air flow, the moment can be 95% ~ 98% evaporation of water, only a few seconds to complete the drying time, especially for drying heat sensitive materials.
B. Product has a good uniformity, fluidity and solubility, high purity and good quality.
C. Production process is simplified, convenient control. The moisture content of 40 ~ 60% (90% of special materials) of the liquid can be dried into a powder product, after drying without crushing and screening to reduce the production processes, improve product purity, product size, bulk density, water, within a certain range can be adjusted by changing the operating conditions, control and management are very convenient.

Use:
Spray drying is a liquid process shaping and drying industry’s most widely used technology. Ideal for from the solution, emulsion, suspension and plasticity of materials generated in the liquid paste powder, granular or bulk solid products. Therefore, when the finished product particle size distribution, residual moisture content, bulk density and particle shape must meet precise standards, the spray drying is a very good process.
