What is the difference between a drying oven and a vacuum drying oven

Drying box
Drying oven is a commonly used instrument and equipment, mainly used to dry samples, but also to provide the temperature environment required for experiments. Drying oven applications are in various industries such as chemical industry, electronics, casting, automotive, food, machinery, etc. Generally, it is divided into galvanized steel plate and stainless steel liner, pointer and digital display, natural convection and blast circulation, conventional oven and vacuum type
Scope of application: Electric blast drying box (hot air disinfection box) is used for drying, baking, wax melting, and sterilization in industrial and mining enterprises, laboratories, and scientific research institutions.
Control features: With parameter memory protected due to power failure and crash state data loss, and call recovery function.
The performance characteristics of the current domestic new type oven are as follows:
◆ Adopt domestic * streamline circular arc design, the shell is made of cold rolled steel plate, and the surface is electrostatically sprayed with plastic;
◆ The temperature control system of this machine adopts microcomputer single chip technology to control temperature, timing, and overheat alarm;
◆ Reasonable air duct and circulation system to minimize temperature uniformity changes in the working room;
◆ The display is double screen high brightness Nixie tube display, with accurate and intuitive indication, superior performance, and touch key setting adjustment parameters;
◆ The temperature control sensor adopts original imported capacitive components;
◆ With timing and timing functions;
◆ The inner liner is made of mirror stainless steel material; Semicircular corners are easy to clean;
◆ The height and number of shelves in the workshop can be adjusted arbitrarily according to user requirements;
◆ Imported motor and fan blades are used, with a slight amount of air circulation, which can eliminate the doubts of users about the fear of blowing away small or powder related items;
◆ The box door has a large viewing angle of thermal insulation tempered glass, which is convenient for users to observe. The use of nano material door seals and thermal insulation materials makes the performance of the entire machine more superior
Vacuum drying oven
The vacuum drying oven is specially designed for drying heat sensitive, easily decomposed, and easily oxidized substances. It can inject inert gases into the interior, especially for some items with complex components, which can also be quickly dried.
Scope of application: Vacuum drying boxes are widely used in research and application fields such as biochemistry, chemical pharmaceuticals, medical and health care, agricultural research, environmental protection, etc., as powder drying, baking, and various types of glass containers
For disinfection and sterilization only. It is particularly suitable for fast and efficient drying of materials with drying heat sensitivity, easy decomposition, easy oxidation, and complex components. Vortex Flowmeter
Structure and working principle
The shell of the electrothermal vacuum drying box is formed by stamping and welding steel plates. The surface of the shell is treated with high-strength electrostatic spray coating, and the paint film is smooth and firm. The working room is made of carbon steel plate or stainless steel plate
It is welded and filled with insulation cotton between the working chamber and the shell. The interior of the working room is equipped with a test object shelf for placing various test objects. A mica heater is installed around the outer wall of the working room. The door seal is made of silicon
Rubber strips are sealed, and a mirror for observation is provided on the box door. The evacuation and inflation of the electric vacuum drying box are controlled by electromagnetic valves. The electrical box is located on the left or lower side of the box, and the front panel of the electrical box is equipped with a vacuum
Air meters, temperature control instruments, and control switches are equipped with electrical components inside the electrical box.
The electrothermal vacuum drying box can maintain a certain degree of vacuum in the working room and use an intelligent digital temperature regulator to set, display, and control the temperature. The temperature regulator uses computer technology for calibration
Collecting and processing indoor temperature signals can automatically maintain a constant temperature in the studio. The temperature control system is a P.I.D intelligent temperature control system with reliable performance and convenient use.
The intelligent temperature regulator has an overtemperature protection function. If the temperature in the working chamber exceeds the set temperature value during the operation of the equipment, the overtemperature protection circuit acts to cut off the heating circuit.
Advantages of Vacuum Technology Drying
Compared to conventional drying technology, it has the following advantages
◆ The vacuum environment greatly reduces the boiling point of the liquid that needs to be expelled, so vacuum drying can be easily applied to heat sensitive substances;
◆ For samples that are not easy to dry, such as powder or other granular samples, using vacuum drying can effectively shorten the drying time;
◆ Various mechanical components or other porous samples with complex structures are cleaned and then vacuum dried, leaving no residual material after complete drying;
◆ Safer use - completely eliminate the possibility of oxide explosion when exposed to heat under vacuum or inert conditions;
◆ Compared to ordinary drying relying on air circulation, powdered samples will not be blown or moved by flowing air;
Control features: With parameter memory protected due to power failure and crash state data loss, and call recovery function.
