Overview:

Spray drying is a liquid process shaping and drying industry, the most widely used technology. Ideal for from the solution, emulsion, suspension, and can pump the liquid raw material to generate paste powder, granular or bulk solid products. Therefore, when the product particle size distribution, residual moisture content, bulk density and particle shape must conform to precise standards, spray drying is an ideal process.

Principle:

1 spray drying equipment is a new and efficient drying device, which can make the solution, emulsion, suspension, solution or melt cream paste, spray-dried, usually in a few seconds to tens of seconds. evaporation of moisture within, into line with production requirements of the powder, granular, round hollow ball or granular product.

2 air through the heater into the hot air into the device in the drying room at the top of the hot air distributor and evenly into the drying chamber and spiral rotation, while the liquid sent to the device in the drying room at the top of the centrifugal atomization device, the liquid sprayed mist into tiny droplets, so that air and liquid flow and heat exposure, moisture evaporates quickly, in a very short period of time drying is finished. Continuously from the drying tower finished bottom and cyclone in the output from the turbine exhaust gas evacuation.

Features:

1 fast-drying, liquid atomization by the greatly increased surface area, the hot air flow, moisture content 40% ~ 90% of the material can be evaporated in an instant 95% to 98% of the water to complete the drying time is only take a few seconds, especially suitable for drying heat sensitive materials.

2 the product has a good uniformity, mobility and solubility, high purity and good quality.

3 to simplify the production process, convenient control. For 40 to 60% moisture content (up to 90% special materials) of the liquid can be dried into a powder product, dried without crushing and screening to reduce the production processes, improve product purity. Product particle size, bulk density, within a certain range can be adjusted by changing the operating conditions, control and management is very convenient.
