Vacuum spray dryer

Hawach’s vacuum spray dryer is an outstanding product since its ability to spray dry under low temperatures. This strength makes it possible to be widely used for heat-sensitive materials without changing their original property.

Features of Hawach’s vacuum spray dryer1. The entire experimental process of spray drying can be completed at 50-130°C, which greatly reduces the drying temperature and is ideal for heat-sensitive materials.2. Colored touch screen vacuum spray dryer, the stable temperature during operation, high automation.3. The feed speed of the peristaltic pump can be adjusted at any time.4. Normally-distributed powder diameter, good fluidity, acceptable low noise.5. High-quality stainless steel materials coating vacuum spray dryer, anti corrosion, easy to use, and clean.6. The jet is automatically dredged (through the needle) and the frequency is adjustable.

Minimum sample size: 50mL (depending on the difference in solid content of the material)4. Nozzle diameter: 0.5mm, 0.7mm, 1mm, 1.5mm, 2mm5. Machine power: 6KW 380V 50HZ6. Vacuum degree:-0.05 ~ 0.06MPA7. Size: 900 × 700 × 1700MM (L × W × H)8. Weight: 200kg

Applications of Hawach’s vacuum spray dryerIt can obtain powder particles with excellent fluidity under low temperature conditions for Chinese medicine, natural product extracts, and fruit juices, etc. Perfect for heat-sensitive materials, such as biological products, extracts of natural products of traditional Chinese medicine with high sugar content, heat-resistant polymer materials, materials that vaporize when heated, various inorganic materials, etc.

Closed loop spray dryer

Closed loop spray dryer is a dryer for organic solvents. Due to the potential explosion and flammability hazards, spray drying of flammable and explosive organic solvents has been difficult and prohibited. However, in many important new technology fields of research and application, there is an urgent need for spray drying or granulation of organic solvents. In response to this challenge, Hawach successfully launched the closed loop spray dryer suitable for organic solvent drying.

Features of Hawach’s closed loop spray dryer1. Easy operation and user friendly: PLC automatic control, experimental parameters can be changed at any time.5. Stable operation with the use of high quality equipment.6. Convenient material preparation: only 20-30 ml of materials are needed, large amounts of materials are also able to be prepared.7. Concentric head closed loop spray dryer, good results ensured.8. Temperature protection: automatically control the fan operation even if the operator makes mistakes.9. Durable fan, will not be polluted during operation.

Application of Hawach’s closed loop spray dryer1. Aqueous solutions and most organic solutions, heat sensitive materials such as biological products, biological pesticides, enzyme preparations, and other materials.2. Easily oxidized materials.3. Materials that produce poisonous gas during drying.
