Steam Thermal Oil Hot Water Heated Vacuum Tray Dryer For Flexible Heat Supply

The steam, thermal oil or hot water heated vacuum tray dryer places wet material in trays and dries it in a negative pressure vacuum environment created by a vacuum pump, while a heating medium is circulated between the jacket and the pipes for heat conduction drying. The evaporated moisture is then removed by the vacuum pump.

The heat source is flexible: low-pressure steam, thermal oil or circulating hot water can be selected to suit the plant, so the dryer can reuse an existing heat supply. Minimal heat loss keeps operation economical, and drying under vacuum lowers the boiling point of the material.

Note: The above data is for reference only. If you have any special requirements, our factory can provide design and consultation services.

Wet material is loaded into trays inside the sealed chamber and the vacuum pump lowers the internal pressure, so the boiling point of the material falls and drying proceeds at low temperature. The selected heating medium, low-pressure steam, thermal oil or circulating hot water, is circulated between the jacket and the pipes to conduct heat into the trays, and the evaporated moisture is removed by the vacuum pump. Heat loss is minimal, so the supplied heat is used efficiently.

1. Wet material is placed into trays inside the drying chamber.
2. The vacuum pump creates a negative pressure vacuum environment.
3. A heating medium is introduced between the jacket and the pipes for heat conduction drying.
4. The moisture evaporated from the material is removed by the vacuum pump.
5. Recovered solvent is condensed and collected through a condenser and a buffer tank.

• Flexible heat source: low-pressure steam, thermal oil or circulating hot water.
• Heat conducted through the jacket and internal pipes.
• Dries under vacuum so the boiling point of the material is lowered.
• Minimal heat loss keeps operation economical.
• Static tray drying preserves the shape of the dried material.
• Sterilization before drying with no impurities introduced, meeting GMP requirements.

It is suitable for low-temperature drying of heat-sensitive materials and is widely used in the pharmaceutical, chemical, food and electronics industries, particularly where an existing steam, oil or hot water supply can be reused.

• Plants with an existing low-pressure steam, thermal oil or hot water supply.
• Pharmaceutical, chemical, food and electronics industries.
• Heat-sensitive materials that require even drying.
