Centrifugal spray dryer milk powder dryer fruit powder liquid dryer powder spray drying equipment
High Speed Centrifugal Spray Dryer
Introduction
Descriptions
The Spray drying is the technology most widely used in the liquid technology shaping and in the drying industry.The drying technology is most suitable for producing solid powder or particle products from liquid materials,such as:solution, emulsion, suspension and pumpable paste states,For this reason,when the particle size and distribution of the final products, residual water contents, mass density and the particle shape must meet the precise standard, spray drying is one of the most desired technologies.
Features
LPG series high-speed centrifugal spray dryer consists of liquid conveying, air filtering and heating, liquid atomization, drying chamber, exhaust collection and control system, etc. The characteristics of each system are as follows.
1. Liquid conveying system consists of liquid tank, magnetic filter, pump, etc. to ensure that the liquid enters the atomizer smoothly.
2. Air filtration system and heating system Before entering the heater, the fresh air should pass through the front and rear filters before entering the heater for heating. The heating methods are electric heater, steam radiator, gas furnace, etc. The choice of which method depends on the customer's site conditions. To ensure that the drying medium has high purity when it enters the drying chamber, the heating air should pass through the high-efficiency filter before entering the drying chamber.
3. Atomization system
The atomization system consists of a high-speed centrifugal atomizer with frequency converter, etc. The powder from the high speed centrifugal atomizer is between 40-120 microns.

Principle
After been filtered and heated the air enters into the air distrbutor on the top of the dryer.The hot air enters into the drying room in the spiral form and uniformly. Passing through the high-speed centrifugal sprayer on the top of the tower,the material liquid will rotate and be sprayed into the extremely fine mist liquid beads.Trough the very short time of contacting the heat air,the materials can be dried into the final products.The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower.
