TC-FYG Back Pressure High Temperature Retort Sterilizer

This instrument is designed according to the requirements of the GB/T 10004-1998 standard for retort-resistant composite films and bags. The back pressure retort sterilizer is a small microcomputer-program-controlled device that uses electric heating to directly inject water into the sterilization chamber, generating high-pressure steam required for retorting. It is suitable for sterilizing items such as food packaging bags and related films. After sterilization, rapid cooling for 3 minutes is achieved using external compressed air and water pressure, reducing the temperature of items inside the chamber to 30–40°C. It is also an ideal equipment for food research institutions conducting sterile packaging tests.

TC-FYG Back Pressure High Temperature Retort Sterilizer

★ Microprocessor control, fully automated testing process

★ Automatic protection against overtemperature, overpressure, water level issues, and leakage

★ Air cooling system, saving water and electricity

★ Equipped with back pressure function to prevent bag bursting

★ Overtemperature protection: Microprocessor detects and stops operation with an alarm when temperature exceeds the normal range

★ Overpressure protection: Safety valve automatically releases pressure when exceeding the normal range of 3 kg/cm2 (0.3 MPa) (manual pressure release switch also included)

★ Water level protection: Low water level detection (stops heating and triggers alarm when water level is below normal)

★ Leakage protection: Equipped with French LONON leakage protection device

★ Safety interlock device: End cover positioning pressure boost, interlock linkage function with synchronized alarm

Technical Parameters

1. Test volume: 50L

2. Chamber dimensions: Φ300mm × 750mm depth

3. Operating pressure: 0–2.5 kg/cm2 (0–0.25 MPa)

4. Operating temperature: 10°C above room temperature to 135°C

5. Operating pressure: 2.5 kg/cm2 (0.25 MPa)

6. Design pressure: 3.5 kg/cm2 (0.35 MPa)

7. Temperature control: Microprocessor-controlled (with constant temperature timing device). Heating, constant temperature, and cooling are all controlled by the microcomputer, with an additional fan to accelerate cooling (shortening the overall sterilization time).

8. Temperature display range: 0–999 minutes

9. Pressure gauge range: -0.1–0.3 MPa, full stainless steel pressure vacuum gauge

10. Heating source: Copper electric heater or stainless steel electric heater

Measurement Principle

Add distilled water, place the sample, tighten the container lid → Turn on the power → Set the test temperature and time → Press the start button to begin the test → The exhaust valve automatically opens to remove non-steam gases → When the temperature reaches 100°C, the exhaust valve automatically closes → Upon reaching the test temperature, the constant temperature test begins → After the set test time is reached → The air cooling device activates for rapid and uniform cooling → Back pressure replenishment → When the temperature drops to 40°C → The test ends, and the sample is removed.
