Low-temperature vacuum drying ovens are ideal for drying heat-sensitive materials that are prone to decomposition, polymerization, or degradation at high temperatures. These ovens can be sterilized before the drying process, ensuring no impurities mix into the material during operation. As a static vacuum dryer, they preserve the shape of the dried material and are widely used in pharmaceuticals, food processing, chemicals, electronics, and other industries.
The working principle involves heating and drying under vacuum conditions. A vacuum pump is used to remove moisture, accelerating the drying process. By adjusting the vacuum level and temperature, the drying rate can be significantly improved. If a condenser is used, solvents can be recovered efficiently. With the use of specific vacuum pump systems, such as SK series water ring pumps or ZSWJ series jet pumps, a condenser may not be required.
Key features include:
1. The system balances heating and vacuum to maintain a stable boiling state without overflow.
2. Drying occurs in a boiling state, resulting in a porous structure that improves solubility after grinding.
3. The design provides a larger and more uniform heating area compared to conventional vacuum dryers.
4. High flatness requirements for both the material and heating plates ensure even drying.
5. Compressed gas or steam creates a "gas needle/air knife" to break up crusts, speed up concentration, and prevent spillage.
6. Multi-channel vacuum systems ensure even pressure distribution and avoid re-moistening of the material.
7. Optional nitrogen generators offer energy-efficient inert protection.
8. Steam recovery units maximize energy savings.
9. CIP cleaning systems support various cleaning modes like steam, soaking, and spraying.
10. Can be heated using steam, hot water, or other heat sources.
11. Optional industrial one-piece machine with touch screen and GAMP5-compliant control system.
12. Data printing and paperless recording capabilities for process monitoring.
