Variable Pressure Vacuum Drying Machine


Vacuum Drying Machine


Technical Parameters:

1. Learn technology from Germany Peize Company, scientific drying method.

2. The condenser design is reasonable, stainless steel manufacturing, life assurance over 20 years, Below 20℃ cryogenic condenser water system designed for ensuring the condenser effect. minimize the impact of moisture on the vacuum pump.

3. During the heating process, the pressure changes automatically according to the temperature of the body. and the pressure in the vacuum tank can be reduced periodically to the reasonable value.Create the most suitable condition for the equipment body insulation moisture evaporation, and the water evaporation process is in a smooth state.

4. Compared with the conventional vacuum drying equipment, saving more than 30% energy.

5. Can effectively solve the problem of rust in the iron core drying process, the drying effect can reach deep insulation center.

6. Device uses two detection range vacuum gauge to test vacuum signal, to ensure the process accurate and reliable.

7. Use schneider electrical components products to ensure the control system stable and reliable.

8. Designed and manufactured in accordance with national regulations to ensure equipment operation, chain protection measures complete.

9. Large square thank door with double O-ring structure, sealing reliability improved significantly.

10. In the system, the main components of a modular design, the factory will assemble debugging, before leaving the factory greatly reducing the workload of equipment on-site installation, while improving the reliability and quality of the installation system installation.


Product Technical process:

The drying heating principle of variable pressure method is to use the steam evaporated from the dryer body as heat transfer medium for convection heat transfer in vacuum state, The drying process is divided into four stages.


Preheat stage:

This section of the tank in low vacuum state, convective heat transfer by the evaporated water vapor, make the product heat transfer efficient, temperature uniformity. During the preheating process, vacuum drying air discontinuously is. needed to ensure that the water vapor in the drying tank is in the saturated state, ruled out the possibility of water vapor condensation in the body surface. Such a reciprocating cycle, the heating efficiency inside the tank improve continuously. the temperature distribution is uniform, and the moisture in the deep insulation can be continuously evaporated.


Variable pressure dehydration period (drying stage):

After preheat stage and the temperature of the equipment body reaches a predetermined value, it is the variable-pressure dehydration stage. The first step is vacuum drying. A portion of the evaporation water vapor is pumped out, raising the degree of vacuum, closing the valve. Continue to allow remaining steam exchange with heat.supplementing the loss of heat which is caused by insulation material moisture vaporization, The moisture in the insulation evaporates constantly, the degree of vacuum was reduced. After a period of time continue to vacuum.This process cycles until the body temperature rises to required temperature for the process, preparing for the final drying stage.


The final dry conditions:

In the variable pressure dehydration stage, due to the evaporation of water was siphoned off largely, the vacuum degree of the drying tank will gradually increase. When the vacuum degree reaches a process requirements predetermined degree, that is, into the final dry stage. By this time, continuously vacuumed the drying tank, residual moisture in the insulation layer continuously pumped until the dry end judgement stage.


End of judge:

The primary principle of the end judgment is to measure the pressure rise rate of water vapor in the vacuum tank, and compare and judge with the value of the process requirement.The end judgement qualified equipment is. automatically shut down, then the product can be released.
