High Speed Pharmaceutical Dryers Centrifugal Industrial Powder Spray Drying Machine

Product description High Speed Spray drying Machine is a 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...

Working principle and process


1. Applicability

First of all, it must meet the basic operation requirements of plastic drying, including good material handling (feeding, transportation, hot air, heat transfer, discharge, etc.), and can meet the basic requirements of drying effect, product quality, and drying speed.

2. Mode of operation

The operation mode is simple and easy to learn, avoiding complicated settings, so as not to delay the time and cost of training technical workers.

3. Simple structure

The structure of the dryer needs to be simple, and the accessories need to be easily replaced and purchased.

4. Drying temperature

Drying temperature refers to the temperature of the air entering the drying barrel. Due to its physical properties, such as molecular structure, specific gravity, specific heat, and moisture content, each raw material has certain limits during drying. When the temperature is too high, it will cause Part of the additives are volatile or agglomerated, and too low will make certain crystalline raw materials unable to achieve the required drying conditions.

5. Drying time

Drying time refers to the pre-drying time before the raw materials are formed. If the drying time is too long, the raw materials will deteriorate or agglomerate or waste energy. If the drying time is too short, the moisture content will be too high.

6. Air volume

It can be said that the air volume represents the dehumidifying capacity of the dehumidifying dryer. Because the air volume is the only medium that takes away water from the raw materials, the size of the air volume will directly affect the quality of the dehumidification effect. If the air volume is too large, the return air temperature will be too high, which will cause overheating and affect the stability of the dew point; if the air volume is too small, the moisture in the raw materials cannot be completely taken away.

7. Dew point temperature


Dew point temperature refers to the temperature when the gas is cooled to condense the moisture contained into water droplets, which is a unit to measure the dryness (humidity) of the gas. The less moisture in the gas, the lower the dew point temperature. A good dryer dew point should be able to reach a dew point temperature of -40°C.
