Technical advantages of vacuum spray dryer

　　Vacuum spray dryerIt belongs to the field of drying technology and belongs to the field of thermophysical engineering. It is widely used in pharmaceutical, biochemical, fine chemical, biological and other industries. It is easy to oxidize, dry liquid materials containing organic solvents and recover solvents. The vacuum spray dryer has the practicability and economy of energy conservation, emission reduction and low carbon. The vacuum spray dryer is mainly used in universities, research institutes and laboratories of food, medicine and chemical enterprises to produce micro particle powders. It has broad spectrum applicability for all solutions, such as emulsion and suspension. The vacuum spray dryer is suitable for drying heat sensitive substances, such as biological products, biological pesticides, enzyme preparations, etc. Some laboratories are used for the preparation of conventional powders or the drying of materials,Vacuum spray dryerCan choose laboratory spray dryer, small size, fast speed, low noise, simple operation.

The vacuum spray dryer is a device that removes moisture from the internal parts of the container by pumping out the air inside the container to reach a predetermined vacuum degree. When the vacuum spray dryer is drying, the tank is in a vacuum state, and the jacket is heated by hot water (or steam, heat transfer oil). As the tank rotates at a low speed, the materials move up and down in the tank, inside and outside in a "diamond shaped trajectory", absorb and evaporate, and the water vapor is continuously discharged through the vacuum pipeline to achieve the purpose of drying the materials. At the same time as drying the mixture, built-in spray, filtration, crushing and other devices can be installed according to customer requirements to achieve its multifunctional operation.

The whole process of vacuum spray dryer is automatic, pipelined, continuous and programmed. The drying process is completed in a vacuum low-temperature state, with heat sensitive materials remaining unchanged and free from bacterial contamination. The vacuum spray dryer is suitable for drying all kinds of difficult materials. The dryness (moisture content) of the material can be adjusted. The energy consumption is only one third of that of the centrifugal spray with the same output. Adopting PLC touch screen operation control and equipped with continuous protection device. The vacuum spray dryer is reasonable in design, compact in structure, convenient in installation and commissioning, and suitable for placement under most working conditions.

Technical features of vacuum spray dryer:

1. The vacuum spray dryer can realize continuous feeding and discharging under vacuum state, and the feeding amount can be set freely as required.

2. The heating system can use various forms such as steam, hot water, and electric heating to convert hot oil heating.

3. The drying temperature can be adjusted from 25 ℃ to 80 ℃, and continuous discharge can be started after 20 minutes to 60 minutes until the batch is completed.

4. The track is made of PTFE material, which runs smoothly, reliably, and has a uniform heating surface. The track speed can be adjusted to 2-5 layers, which can be determined according to the user's production requirements.

5. Equipped with an automatic crushing system under vacuum conditions,Vacuum spray dryerThe dry particle mesh size can be arbitrarily selected according to the user's requirements.

6. Equipped with CIP in-situ cleaning system, automatic cleaning is fast and convenient.

7. The vacuum spray dryer adopts the vacuum unit and has been carefully designed and combined, with continuous large capacity air extraction rate and stable vacuum degree.

8. The vacuum spray dryer has low energy consumption, no three wastes and low noise.
