Project Description

Vacuum drying oven

Vacuum Drying Chamber China Manufacturer & Supplier

Vacuum Drying Oven is a frequently used drying instrument in the laboratory, featuring an artificial vacuum environment to especially dry heat-sensitive, easily decomposed, and easily oxidized materials.

The interior of the chamber is vacuumed by a vacuum pump prior to drying. It is allowed to be filled with inert gas if necessary.

A vacuum pump paired with the drying oven can be provided if requested.

The vacuum drying chamber can minimize the damage and change for the specimens to the utmost extent during the drying at high temperatures. Reducing the possibilities of desquamation and oxidation reaction in the drying process is also the shining point of this vacuum drying oven, which is the reason why it is well applicable to test pieces with active chemical properties. Such as flammable solvents evaporation, although it is with a high risk of explosion if operated in an ordinary drying oven, danger can be avoided once putting the solvents into a vacuum drying cabinet with a low pressure to evaporate.

Both benchtop and vertical vacuum drying ovens are available from Amadetech. In order to meet various needs of dimensions and applications, our vacuum drying oven’s capacities cover from 10 liters to 913 liters.

Vacuum Drying Oven Features

  • Housing is made of cold-rolled steel sheets through precision welding and coated with quality baking varnish to ensure smoothness and fastness.
  • The cuboid chamber is equipped with multideck racks to maximize the working capacity.
  • The tempered glass with two layers on the door offers a clear view for inspection.
  • The degree of tightness of the door when closed is adjustable.
  • A door gasket fabricated from integrally molded silicone rubber ensures a high vacuum of the drying chamber during use.
  • The interior can be filled with inert gases(optional function).
  • There are double digital screens to indicate the set value and real-time parameters simultaneously.
  • Microprocessor temperature controller provides accurate and reliable running data to reduce the drying period by 40% compared with the traditional equipment.
  • A vacuum environment with low pressure offers high resistance of test pieces to oxidization in the whole process of dry.
  • The drying process is programmable(optional function).
  • Fitted with over-temperature protection and power-off protection to prevent a hazard to the maximum.
What Are Advantages of Vacuum Drying Oven?2021-06-23T03:07:56+00:00
  • The boiling point of liquid to be evaporated is significantly lowered because of vacuum conditions provided by this chamber, resulting in wide applications to thermosensitive substances.
  • For materials that are not easy to be dried, for example, powder or other granular samples, the vacuum drying method can effectively shorten the drying time.
  • It leaves no residues after being dried for mechanical parts with complex structures or items with many bores.
  • Compared with the heat distribution of a regular drying oven by means of air convection, powdered samples tested using the vacuum drying chamber won’t move or be blown by air throughout the run.
How to Use Vacuum Drying Oven?2021-06-23T03:27:31+00:00
  1. Plug in power and check all parts and ensure samples to be tested are in place.
  2. Place the test pieces on the shelves in the chamber and close the door to guarantee a closed seal.
  3. Connect the vacuum pump to the drying oven through an air tubing, and turn off the air balance port.
  4. Start the vacuum pump and open the vacuum valve in sequence. Vacuuming is in process.
  5. Observe the value on the pressure gauge, and stop it until the pressure value is close to “-1” (shutdown sequence must be vacuum valve first, then vacuum pump switch).
  6. Press the Power button to turn on the vacuum pump and then set the drying temperature and duration time to enter the drying state.
  7. Pay attention to the pressure value during drying. Repeat above step 4 to vacuumize it again If the vacuum degree drops in the process.
  8. After drying time is up with buzzing, turn off the vacuum drying oven.
  9. Open the air balance port to balance the air pressure inside and outside the chamber.
  10. Open the oven door to take out the test piece.

Tip: The manual operation sequence of the vacuum pump must follow the above step. It can’t be reversed.

Why Does Vacuum Drying Oven Need To Be Vacuumized Before Heated Instead of Being Heated Before Vacuumized?2021-06-23T03:55:39+00:00
  • The goal of vacuuming is to get rid of the gaseous water in the specimen which can be pumped out. If heated first, the gas will expand in the cabinet, which has a potential threat to both the specimen and the drying oven.
  • If heated first, the heated air will be pumped out into the vacuum pump to result in overheating the machine to damage the pump.
  • Heated air will be exported to the vacuum pressure gauge leading to temperature rise. If the temperature exceeds the given range, the indicated value of the gauge will generate errors.
