The difference between vacuum drying oven and drying oven
Drying oven is a commonly used instrument and equipment, mainly used to dry samples, but also can provide the temperature environment required for the experiment. Drying oven is used in various industries such as chemical, electronics, casting, automotive, food, machinery and so on. Generally divided into galvanized steel and stainless steel liner, pointer and digital display, natural convection and blast circulation, conventional oven and vacuum type. Scope of application:
Electric blast drying oven (hot air sterilization oven) is for industrial and mining enterprises, laboratories, scientific research units, etc. for drying, baking melting wax, sterilization role. Control features:
With a power outage, dead state data loss and protection of parameter memory, call recovery function. At present, the new type of domestic oven has the performance characteristics:
1, the domestic first streamline arc type design, the shell is made of cold rolled steel plate, surface electrostatic spraying;
2, the machine temperature control system using microcomputer microcontroller technology, temperature control, timing, over-temperature alarm;
3, a reasonable air ducts and circulatory system, so that the indoor temperature uniformity of the change is small;
4, the display of the dual-screen high-brightness digital tube display, the value of the accurate and intuitive, superior performance, touch keys to set the adjusting parameters;
5, the temperature control sensor is used capacitive original imported components;
6, with timing and timing function;
7, the inner liner are made of mirror stainless steel; semi-circular corners are easy to clean;
8, indoor shelves can be adjusted with the user's requirements of the height and how many shelves;
9, the use of imported motors and air blades, trace wind circulation, which can enable users to eliminate the cultivation of fine or powder off the items worry about blowing away the doubts;
10, oven door with a large perspective insulation tempered glass, easy for users to observe, the use of nano-materials door seal and insulation materials so that the performance of the machine embodies more superior.
Vacuum drying oven designed for drying heat-sensitive, easy to decompose and easy to oxidize the material and design, can to the internal inert gas, especially some of the complex composition of the goods can also be rapid drying.
Scope of application:
Vacuum drying oven is widely used in biochemistry, chemical and pharmaceutical industry, medical and health care, agricultural research, environmental protection and other research applications, for powder drying, baking and various types of glass containers for disinfection and sterilization only. Especially suitable for drying heat-sensitive, easy to decompose, easy to oxidize substances and complex composition of the goods for rapid and efficient drying treatment. Structure and working principle The shell of electric vacuum drying oven is made of steel plate stamping, folding and welding, and the surface of the shell adopts high-intensity electrostatic plastic spraying and coating treatment, with smooth and solid paint film. The workshop is made of carbon steel plate or stainless steel plate folded and welded, and the workshop is filled with heat preservation cotton between the workshop and the shell. The interior of the studio is equipped with specimen shelves for placing various test items, and the outer wall of the studio is equipped with mica heaters. The door seal adopts silicone rubber strip sealing, and the door of the oven is equipped with a sight glass for observation. Electrically heated vacuum drying oven is controlled by solenoid valve for evacuation and inflation, electrical oven is on the left side or the lower part of the oven, the front panel of the electrical oven is equipped with vacuum meter, temperature control meter and control switch, etc., and the electrical oven is equipped with electrical components.
Electrothermal vacuum drying oven can make the working chamber keep a certain degree of vacuum and adopt intelligent digital temperature regulator to set, display and control the temperature.The temperature regulator adopts computer technology to collect and process the temperature signal in the working chamber, which can make the temperature in the working chamber keep constant automatically.
The temperature control system is P.I.D intelligent temperature control, reliable performance, easy to use.
Intelligent temperature regulator has over-temperature protection function. If the temperature inside the working chamber exceeds the set temperature value during the working process of the equipment, the over-temperature protection circuit will be activated and the heating circuit will be cut off. Advantages of vacuum technology drying than conventional drying technology has the following advantages
1, the vacuum environment greatly reduces the boiling point of the liquid that needs to be driven off, so vacuum drying can be easily applied to heat-sensitive substances;
2, for samples that are not easy to dry, such as powder or other granular samples, the use of the vacuum drying method can effectively shorten the drying time;
3, all kinds of complex construction of the mechanical parts or other porous samples after Cleaning after the use of vacuum drying method, completely dry without leaving any residual material;
4, the use of safer ---- in a vacuum or inert conditions, completely eliminating the possibility of explosion of oxides in the presence of heat;
5, compared with relying on the ordinary drying of air circulation, the powdered samples will not be blown by the flow of air or movement; control features:
With a power outage, dead state data loss and protection of parameter memory, call recovery function. Performance characteristics:
1, using the first streamline arc type design, the shell is made of cold-rolled steel plate, surface electrostatic spraying; 2, the machine temperature control system using microcomputer microcontroller technology, temperature control, timing, over-temperature alarm;
3, the display for the dual-screen high-brightness digital tube display, showing the value of the accurate and intuitive, superior performance, touch keys to set the parameters of the adjustment;
4, the temperature control sensors used in capacitive imported components;
5, using the imported motors and air blades; with timer and the air blades. Imported motor and wind blade; with timing and timing function;
6, the inner liner are made of stainless steel; semi-circular corners are easy to clean.
