High speed centrifugal spray dryer
Spray drying equipment is a new type of high-efficiency drying process equipment. It can dry solution, emulsion, paste and heat sensitive materials through spray. Generally, it evaporates water within a few seconds and transforms into powdered, granular hollow spheres or round products that meet production requirements. It is an ideal drying equipment for industries such as pharmaceuticals, biotechnology, and chemical engineering.
High speed centrifugal spray dryer Positioning of a new type of high-efficiency drying process Equipment features fast drying speed, simplified production process Design essentials Uniform feeding speed/Used spray dryer treatment

The liquid material (filtered liquid material) is fed into a high-speed rotating centrifugal atomization disk and is subjected to the centrifugal force of the rotating disk
The liquid material extends into a thin film on the rotating surface and continuously moves towards the edge. When it leaves the edge, it is atomized and passes through atomization
The subsequent droplets (with significantly increased surface area) undergo heat exchange with hot air and quickly complete the drying process within 10-30 seconds.
Design points:
When the atomizing wheel rotates, there must be no vibration.
The rotational speed of the rotating disc must be high, generally ranging from 90 to 60M/s.
The surface of the liquid channel must be very smooth.
4. Uniform distribution of liquid in the fluid channel.

Centrifugal spray
Product Introduction
High speed centrifugal spray drying is a widely used process in liquid process forming and drying industry [3].

Powder and granular solid products are generated from solution, lotion, suspension and paste liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet the standards, spray drying is a very ideal process.
Performance Characteristics
The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds, which is particularly suitable for drying heat sensitive materials.
The product has good uniformity, fluidity, and solubility, 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% for special materials), it is easy to control and manage them by drying them into powder products in one go.

Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, etc.
working principle
The working process of this unit involves the high-pressure input of material liquid through a diaphragm pump, spraying mist like droplets, and then flowing down in parallel with hot air. Most of the powder particles are collected by the bottom discharge port of the tower, and the exhaust gas and its small powder are separated by a cyclone separator. The exhaust gas is discharged by a suction fan, and the powder is collected by a pollination tube located at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, with a recovery rate of over 96-98%.
Performance Characteristics
The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated in an instant, and the drying time only needs tens of seconds to tens of seconds. It is particularly suitable for drying heat sensitive materials.
All products are spherical particles with uniform particle size, good flowability, good solubility, high product purity, and good quality.
Widely applicable, according to the characteristics of the material, it can be dried with hot air or granulated with cold air, with strong adaptability to the material.
Simple and stable operation, convenient control, and easy implementation of automated tasks.
