The MDZK series low-temperature pulsating vacuum dryer is mainly suitable for drying thermosensitive materials (Chinese herbal extracts, active substances) under low-temperature vacuum conditions.
Load the material into a drying tray, place it on a flat plate heated inside the box, and continuously dry it at low temperature under vacuum. By continuously reducing pressure and increasing pressure, the solvent is taken away by a vacuum pump (and a condensation recovery system can be added) to achieve rapid drying.
It mainly consists of four systems: drying host, pulsation system, vacuum system, and control system.
1. The pulsating vacuum dryer has a small footprint;
2. Fast drying speed, reducing drying time by nearly 50% compared to ordinary vacuum drying;
3. Pulse vacuum dryer dries evenly;
4. PLC automatic control, automatically completes the drying process according to the properties of the material.
5. Low temperature, integrated heating of the box, uniform temperature.
6. The foam breaking system quickly solves the foaming phenomenon of traditional Chinese medicine extract.
7. Automatic pulse system, timed blowback, controls the vacuum degree inside the box.
8. Large heating area and fast drying rate.
9. PLC fully automatic control system, and can automatically record working temperature pulsation frequency, etc.
The low-temperature pulse vacuum dryer is a highly efficient and energy-saving product developed by Changzhou Ruide Drying Engineering Technology Co., Ltd. based on market demand, years of industry experience, multiple innovative technologies, and new research and development. It mainly solves bottleneck problems such as long soaking and drying cycles of traditional Chinese medicine, difficult material collection, and unreliable material quality.
Low temperature pulse vacuum dryer is a vacuum box type drying device, belonging to static vacuum drying equipment. It works under negative pressure conditions and can be widely used for drying materials in various industries, especially for drying heat sensitive materials or materials with high viscosity and harsh oxygen-containing working conditions. This equipment uses (low-temperature) hot water as the exchange medium, adopts the principle of "high vacuum" laminar flow drying, and uses bubble breaking technology to solve the bottlenecks of material foaming and overflow, coking and carbonization, oxidation and degradation, and long drying cycle in the drying process of traditional Chinese medicine extracts for many years. It is an efficient, energy-saving and low-temperature drying method. At the same time, it can complete online cleaning or soaking cleaning functions, material input and output functions, automatic cooling function inside the box, and automatic feeding function.
