Application range:
This product is widely used in industrial and mining enterprises, colleges and universities, scientific research and various laboratories, such as vacuum leak detection or ceramics, glue, epoxy resin, paint, plastic toys, resin crafts for storing articles or cosmetic bottles under vacuum conditions. Vacuum defoaming treatment in industries such as candles, printer cartridges and glass products.

Features:
1. The rectangular parallelepiped workroom is made of high quality steel or stainless steel. The tempered, bullet-proof double-glazed door is made for observation.
2. The door can be closed tightly, and the integrally formed silicone rubber door seal ring ensures high vacuum inside the oven.
3. Microcomputer intelligent temperature controller has functions of setting, measuring temperature double digital display and PID self-tuning, can control the temperature accurate and reliable.
4, The heating power ratio can be adjusted arbitrarily, to ensure that the low-end temperature control has no disadvantages.
5, The overall vacuum drying process control can provide a programmed vacuum cycle, just set the vacuum time value, holding time value, inflation time value according to your requirements, can further shorten the drying time. For example, the vacuum cycle is controlled by the program, the vacuum is set for 10 minutes, the pressure is maintained for 30 minutes, the air is inflated for 2 minutes, and the number of cycles is 10 times. With each cycle, the humidity is continuously reduced, the drying speed is obviously accelerated, and the number of cycles is up to 99 times. Suitable for dry high moisture content.

Machine workflow:
1, preparation work
2, turn on the dry box power
3. Connect the decompression end of the nitrogen bottle to the “nitrogen interface” behind the tank to adjust the nitrogen inlet pressure.
4. Transfer the items or test pieces that need to be dried to the studio through the track and close the door.
5. Turn on the power and press the start button on the control panel:
1 pumping vacuum and heating at the same time
2 After vacuuming to the set time, the vacuum pump stops working and automatically passes nitrogen.
3 Nitrogen gas is turned on until the set time to close the nitrogen
4 After the state is maintained to the set time, the vacuum pump is restarted.
5 After the set time, the vacuum pump and heater are automatically turned off.
6 manual pressure relief

Remarks: This paragraph is a vertical vacuum drying oven with a working chamber above and a vacuum pump toolbox below. The standard configuration is a rotary vane vacuum pump. The standard configuration liquid water filter can effectively filter out the water vapor extracted from the vacuum box, so as to prevent the water vapor from directly entering the vacuum pump and injecting oil, which affects the service life of the vacuum pump.
