Product Introduction
The steam-heated vacuum oven is a vacuum drying device that uses steam as the heating source. Steam circulates through the flow passages inside the drying racks to speed up the drying process. The steam heat source is generally provided by a steam boiler.
Working principle
The working principle of steam-heated vacuum oven combines steam heating and vacuum technology to achieve high-efficiency, low-temperature drying.
The workflow is as follows: First, the steam system generates steam, which comes into contact with the object to be dried within the inner chamber, transferring heat to the object through heat conduction.
During this process, a vacuum pump removes air from the inner chamber, creating a vacuum environment, thereby lowering the boiling point of water and accelerating the evaporation of water molecules.
When the steam comes into contact with the surface of the object, heat exchange occurs, and the moisture on the surface is carried away in the form of steam, achieving the drying purpose.
This equipment, through steam recycling and vacuum control, makes the drying process highly efficient and energy-saving, and effectively prevents material damage from heat, making it particularly suitable for drying easily decomposed or high-value materials.
Features
The steam-heated vacuum oven is designed with a through-flow drying rack. Based on the principle of hot air rising, it fully utilizes the heat conduction of each rack tube, achieving a high drying rate at a relatively low temperature. It ensures efficient heat utilization and is primarily suitable for drying heat-sensitive materials, materials containing solvents, and materials requiring solvent recovery. Sterilization can be performed before drying, and no impurities are introduced during the drying process. This dryer is a static vacuum dryer, ensuring no damage to the dried material.
Applications
Steam-heated vacuum ovens are widely used in pharmaceutical, chemical, medical, food, light industry, plastics, scientific research and education industries for low-temperature or high-temperature drying and baking. They have the advantages of fast drying speed, low pollution, and no damage to the internal quality of the items to be dried. They are environmentally friendly and green drying equipment that meets GMP requirements.
