Introduction to the vacuum drying oven We talked about the performance characteristics of the vacuum drying oven. Today, we will introduce the structural characteristics of the vacuum drying oven and its working principle.
Vacuum drying box Wuhan Shangchen Test Equipment Co., Ltd. shell produced by steel stamping folding, welding molding, shell surface using high-strength electrostatic spray coating treatment film smooth and strong. The studio uses a carbon steel plate or stainless steel plate folded and welded to form a thermal insulation cotton between the studio and the housing. Inside the studio there is a shelf for the test product. The number of layers of the shelf can be increased according to the customer's needs for placing various test items.
Mica heaters are installed around the outside of the work wall. The door is sealed with a silicone rubber strip and an observation window is provided to observe the interior of the test chamber.
Vacuum evacuation and air-inflating are controlled by solenoid valves. The control system is on the left side or the bottom of the body. The front panel of the control system circuit board is equipped with vacuum gauges, temperature control instruments and control switches. Vacuum drying oven can maintain a certain degree of vacuum in the working chamber and use intelligent digital temperature controller to set, display and control the temperature. The temperature regulator adopts computer technology to collect and process the temperature signal in the working chamber, so that the temperature in the working chamber is automatically maintained at a constant temperature. The temperature control system is a PID intelligent temperature control, reliable performance, easy to use.
Intelligent temperature regulators have over-temperature protection. If the temperature in the working chamber exceeds the set temperature during the operation of the device, the over-temperature protection circuit activates and the heating circuit is shut off.
Compared with the blast drying oven, the vacuum environment created by the vacuum drying oven greatly reduces the boiling point of the liquid that needs to be removed, so vacuum drying can be easily applied to heat-sensitive substances, and secondly, to samples that are not easily dried, such as powders or other granular samples. The use of vacuum drying method can effectively shorten the drying time, and for all kinds of complicated mechanical parts or other porous samples after cleaning, use the vacuum drying box to completely dry without leaving any residual substances, and rely on air circulation blast drying oven Ratio, dry powder samples are not blown or moved by moving air
The most important point is that it is safer to use, and completely eliminates the possibility of the oxide exploding under vacuum or inert conditions to ensure operator safety.
