1、 The purpose of low-temperature vacuum drying oven:

This series of low-temperature vacuum drying ovens is suitable for drying thermosensitive materials that are prone to decomposition, polymerization, or deterioration at high temperatures. Disinfection treatment can be carried out before drying, and there should be no impurities mixed into the material during the drying process. It belongs to a static vacuum dryer, so the shape of the dried material will not be damaged, and it is widely used in industries such as pharmaceuticals, food, chemicals, and electronics.

2、 The principle of low-temperature vacuum drying oven:

Place the dried material under vacuum conditions and heat dry it,Low temperature vacuum drying ovenIt uses a vacuum pump to extract air and moisture, which accelerates the drying rate. When the heating temperature is constant and the vacuum degree is increased, the drying rate can be accelerated. When the vacuum degree is constant, increasing the heating temperature can accelerate the drying rate. By increasing both the vacuum degree and heating temperature, the drying rate is greatly accelerated. If a condenser is used, the solvent in the material can be recovered through the condenser. If SK series water ring vacuum pump or ZSWJ series hydraulic jet vacuum pump unit is used, a condenser is not required.

3、 Vacuumdrying ovenCharacteristics:

1. The system achieves balance between heating and vacuum by controlling the entire process, ensuring that the material is in a moderate to high boiling state without overflowing (monitored);

2. The material is dried in a boiling state, and the paste block is in a loose and porous state. After crushing, the fine powder has a lower bulk density and is more easily dissolved;

3. The drying oven, designed with heating plate layers, has a larger heating area and more uniform heating compared to traditional vacuum ovens;

4. In order to facilitate synchronous drying of every material, it has higher requirements for the flatness of heating vessels and heating plate layers in its design;

5. The low-temperature vacuum drying oven uses compressed gas/steam to form a "gas needle/gas knife" that effectively punctures/cuts through the crust, accelerates the concentration process, and avoids overflow and material escape caused by boiling; At the same time, the device can effectively supplement inert gas, form effective protection for materials, ensure excellent color of active substances and materials, and effectively improve drying speed through convection;

6. Side multi-channel vacuum pumping/air supply ensures that the vacuum inside the system remains uniform even after heating with the plate layer, while effectively avoiding the backflow of condensed water into the material, which may cause local non drying and affect the drying speed;

7. Optional nitrogen generator can be configured to effectively utilize the heat generated during the nitrogen production process while enjoying the protection of inert materials, achieving maximum energy efficiency;

8. Optional steam recovery device for maximum energy savings;

9. Optional CIP cleaning system (with multiple cleaning modes such as steam lubrication, soaking, spraying, etc.);

10. The low-temperature vacuum drying oven can be heated with various heat sources such as steam and hot water;

11. Optional industrial all-in-one machine with touch screen, combined with a control system that complies with GAMP5 rules, for one click operation of the equipment;

12Low temperature vacuum drying ovenThe control system has functions such as online data printing and paperless recorder recording process data.
