Steam air working principle
Step 1: heating process
Start the steam and fan first. Under the action of the fan, the steam and air in the kettle flow forward and backward through the air duct.
Step 2: Sterilization Process
When the temperature reaches the set temperature, the steam valve is closed and the fan continues to run in the cycle. After the holding time is reached, the fan is turned off; the pressure in the tank is adjusted within the required ideal range through the pressure valve and exhaust valve.
Step 3: Cool down
If the amount of condensed water is insufficient, softened water can be added, and the circulation pump is turned on to circulate the condensed water through the heat exchanger for spraying. When the temperature reaches the set temperature, the cooling is completed.
Step 4: Drainage
The remaining sterilizing water is discharged through the drain valve, and the pressure in the pot is released through the exhaust valve.
Steam air retort features:
1. No Steam Cooling Required
- Compressed air is injected into the autoclave.
- Turbine fan breaks up air-cooling mass, forcing steam-air mixture circulation without cold spots.
- Heat distribution controlled at ±0.5°C during sterilization.
2. Efficient Steam-Air Circulation
- Turbine blower forces steam-air mixture from one end to the other, ensuring even heat distribution.
- Saves over 15% of steam by avoiding ventilation system turbulence.
3. Aerodynamic Backlight Plate Design
- Controls steam flow direction and accelerates heat transfer to the product center for heating and cooling.
4. Flexible Pressure and Temperature Control
- Allows counter-pressure cooling for precise control.
5. Wide Application Range
- Suitable for high-temperature sterilization of snack foods, meat products, beverages, etc., in various packaging.
6. Negative Pressure Safety Device
- Prevents manual misoperation and negative pressure formation, ensuring equipment safety.
7. Power Outage Recovery
- Program automatically restores to pre-power outage state, minimizing losses.
8. Triple Safety Interlocks
- Prevents worker misoperation and avoids accidents.
9. Dual Safety Valves and Pressure Sensors
- Eliminates potential safety hazards.
1. Pressurization for Flexible Packaging
- Allows pressurization during heating and heat preservation stages, making it suitable for flexible packaging.
2. Frequency Converter for Fan Motor
- Fan motor is controlled by a frequency converter, enabling slow start and stop to protect the motor, bearings, and other components.
3. Proportional Regulating Valve for Steam Control
- Enables multi-stage temperature rise and linear control, ensuring standardized sterilization.
4. Energy Savings
- No exhaust required, saving about 25% of steam compared to traditional steam sterilization.
- No water used as an intermediate heat transfer medium, reducing steam consumption for heating water compared to water immersion and spray sterilization.
