Constant temperature drying oven

DHG electrothermal air blast constant drying oven operates the air blast circulation drying experiment by the ways of electrical heating. It blows out the hot air through the circulating fan, so as to keep the temperature balance in the box.

A vacuum drying oven is widely used in chemical engineering, biochemical, pharmaceutical, medical care and public health, agricultural scientific research, environmental protection and other research areas. It is applicable for powder drying, baking, as well as the disinfection and sterilization of various glass containers. In particular, it is suitable for rapid and efficient drying treatment of heat-sensitive, easily decomposed, easily oxidized materials and complex components. It can not only lower drying temperature, but prevent some materials from oxidizing in contact with air. In particular, some complicated materials can be dried rapidly. It can maintain a certain vacuum degree in the working chamber, and be filled with inert gas inside. The working chamber adopts stainless steel material, and the shape is horizontal square type, expanding the using space than the circular working chamber.

Working Principle

It is known that a vacuum drying oven is a kind of vacuum drying device under negative pressure. It makes use of a vacuum pump for pumping and dehumidification. A vacuum pump can create a vacuum condition inside the working chamber so that the boiling point of water can be lowered, accelerating the drying process.

Product Advantages

  1. The working chamber mainly adopts high quality steel plate or sanitary stainless steel, with strong corrosion resistance.
  2. The double layer toughened sight glass is bullet proof and high temperature resistance, and easy to observe as well.
  3. The heat source adopts built-in S-type anti-explosion resistance tube, safe and reliable. The heating time can reduce more than 50%.
  4. The microcomputer controller can control temperature accurately and trigger quickly.
  5. The dual-screen digital display panel, with the touch button for adjustment, is more intuitive for users to set and read temperature.
  6. The tightness of the oven door can be adjusted and the synthetic silicon sealing ring takes shape integrally, which ensure the high vacuum degree in the oven.
