Drying Oven and Vacuum Drying Oven difference Drying oven is a commonly used instrument and equipment, mainly used to dry the sample, but also can provide the experimental temperature environment. Drying box application and chemical, electronics, casting, automotive, food, machinery, etc. Industry. Generally divided into galvanized steel and stainless steel liner, pointer and digital display, natural convection and air circulation, conventional oven and vacuum type.

Scope of application: Electric blast drying box (hot air disinfection box) is for industrial and mining enterprises, laboratories, research institutes for drying, baking wax, sterilization.

Control features: It has parameter memory protected by data loss due to power outage and dead status, and the call recovery function.

The current domestic new type oven has the characteristic features:

1. Adopting the domestic first streamline arc design, the shell is made of cold-rolled steel plate and the surface is electrostatically sprayed;

2. The temperature control system of this machine adopts microcomputer single-chip technology, temperature control, timing, over-temperature alarm;

3. Reasonable duct and circulation system, so that the temperature uniformity of the working chamber changes little;

4. It is displayed as a dual-screen high-brightness digital tube display. The display value is accurate and intuitive, and the performance is excellent. The touch-sensitive keys set the adjustment parameters.

5, temperature sensor uses capacitive imported components;

6, with timing and timing functions;

7, the liner is made of mirror stainless steel; semi-circular four corners are easy to clean;

8. The height of the shelves and the number of shelves can be arbitrarily adjusted according to the user's requirements.

9, using imported motors and fan blades, trace air circulation, users can eliminate the confusion about the cultivation of small or powdered items concerned;

10. The box door has a large viewing angle and heat-retaining tempered glass, which is easy for users to observe. The use of nano-material door seals and insulation materials makes the performance of the whole machine more superior.
Vacuum drying oven
The vacuum drying oven is designed to dry heat-sensitive, easily decomposable and easily oxidized materials. It can inject inert gas into the interior. In particular, some complicated components can also be quickly dried.

Scope: Vacuum drying oven is widely used in biochemical, chemical pharmaceutical, medical and health, agricultural research, environmental protection and other research and application fields, for powder drying, baking and all kinds of glass containers for disinfection and sterilization only. It is particularly suitable for the rapid and efficient drying of dry heat-sensitive, easily decomposable, easily oxidizable substances and complex ingredients.

Structure and working principle
Electrothermal vacuum drying oven shell is stamped and folded by steel plate and welded. The surface of the shell is treated with high-strength electrostatic spray coating. The film is smooth and firm. 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. The interior of the studio houses a test shelf for placing various test items, and an mica heater is installed around the outside wall of the work room. The door seal is sealed with a silicone rubber strip, and a sight glass is provided on the door for observation. Electrovacuum vacuum drying chamber evacuation and inflation are controlled by the solenoid valve, electrical box in the box on the left or lower, the electrical box on the front panel with a vacuum gauge, temperature control instruments and control switches, etc., electrical boxes are equipped with electrical components.

Electrothermal 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.

The advantages of vacuum technology drying
Compared with conventional drying technology has the following advantages
1. The vacuum environment greatly reduces the boiling point of the liquid that needs to be removed, so vacuum drying can be easily applied to heat-sensitive substances;

2. For samples that are not easily dried, such as powders or other granular samples, vacuum drying method can effectively shorten the drying time;

3. All kinds of complicated mechanical parts or other porous samples are vacuum-dried after cleaning, and do not leave any residual substances after drying;

4, the use of safer - in the vacuum or inert conditions, completely eliminate the possibility of oxide explosion in the heat;

5, compared with ordinary drying relying on air circulation, powder samples will not be blown or moved by moving air;

Control features: It has parameter memory protected by data loss due to power outage and dead status, and the call recovery function.

Performance characteristics:

1. Adopting the domestic first streamline arc design, the shell is made of cold-rolled steel plate and the surface is electrostatically sprayed;

2. The temperature control system of this machine adopts microcomputer single-chip technology, temperature control, timing, over-temperature alarm;

3. Displayed as dual-screen high-brightness digital tube display, accurate and intuitive indication, superior performance, touch buttons to set the adjustment parameters;

4. The temperature control sensor adopts the capacitor original imported components;

5, using imported motors and fan blades; with timing and timing functions;

6, the liner is made of stainless steel; semi-circular four corners are easy to clean;

7, the door can be completely loosened by the user can be adjusted, the overall shape of the silicone rubber door seal, to ensure high vacuum inside the box;

8. The machine studio is a cuboid structure that maximizes the effective volume. The door adopts a toughened, bullet-proof double-glazed door to allow the user to see at a glance the training items in the observation studio.
