vacuum system

1. This machine adopts high-density silicone sealing strips for sealing at the entrance;

2. Vacuum degree is displayed as a number, using SMC pressure gauge to display real-time vacuum degree and relative pressure display;

3. Machine vacuum degree range: 0KPa to -1000KPa, (vacuum degree: ≤ 265Pa);

4. Vacuum control mode: automatic control, stop vacuuming when the vacuum degree reaches, automatically start when it is below the lower limit, and work in this cycle. After the constant temperature time is completed, stop working; Manually decompress and fill with air or nitrogen;

5. The change in vacuum degree during the product baking process is only displayed for observation and does not save data;

6. Configure a 4-liter direct connection vacuum pump with a power of 550W and a voltage of 220V

Nitrogen filling device (can be manually filled with air for decompression)

1. Pressure regulating valve: controls the nitrogen pressure, and under normal use, the nitrogen pressure is adjusted to around 2 kilograms;

2. Flow meter: controls the size of nitrogen entering the box, with a range of 2L/min-10Lmin;

3. The nitrogen pipeline enters directly behind the box and is equipped with a 2-meter long 10mm nitrogen hose externally;

4. Nitrogen needs to be provided by your company.
