Product Introduction 
The Reverse Pressure High Temperature Retort uses microcomputer program control. It generates high-pressure steam in the retort chamber through electric heating to process food packaging bags, composite films, and other specimens at high temperature. The touchscreen control system allows users to set test temperature, boiling temperature, and timer. The fully automatic reverse pressure air and water inlet system ensures automatic completion of pressure rise, holding, and cooling. After testing, external compressed air and water pressure rapidly cool the retort, bringing the chamber contents down to 30-40°C in about 3 minutes, effectively preventing package rupture caused by rapid pressure release. The equipment simulates the heat and pressure conditions of actual food sterilization processes, providing standardized testing means for quality evaluation of retortable composite films and pouches.

Key Features
Touchscreen Intelligent Control Touchscreen control system for intuitive setting of test temperature, boiling temperature, and timer; simple operation with high automation.
Fully Automatic Reverse Pressure Air and Water Inlet Equipped with a fully automatic reverse pressure air and water inlet system; pressure rise, holding, and cooling are completed automatically without manual intervention.
Electric Heating Direct Steam Generation Uses electric heating to directly inject water into the retort chamber and generate high-pressure steam with high thermal efficiency and uniform retorting.
Rapid Cooling to Prevent Bag Rupture After testing, external compressed air and water pressure rapidly cool the chamber, bringing contents down to 30-40°C in about 3 minutes to prevent package rupture.

Main Technical Specifications

FAQ 
1. What materials is the Reverse Pressure High Temperature Retort suitable for?
It is suitable for retort testing of food packaging bags, retortable composite films and pouches, and related film materials, as well as aseptic packaging experiments in food research institutions.
2. What is the function of the reverse pressure feature?
The reverse pressure function uses external compressed air and water pressure for rapid cooling after testing, balancing internal and external pressure of the package to prevent rupture or deformation caused by rapid pressure release.

3. How long does cooling take after testing?
External compressed air and water pressure provide rapid cooling, bringing the chamber contents down to 30-40°C in about 3 minutes, effectively shortening the test cycle.
4. What are the requirements for water and air sources?
The water source requires distilled or purified water at ≥0.28 MPa with regulated pressure. The air source requires ≥0.25 MPa with constant pressure regulation. These are mandatory conditions for proper operation.
5. What standard does the equipment comply with?
It is designed and manufactured according to GB/T 10004-1998 (Retortable composite films and pouches), meeting standardized requirements for food packaging retort resistance testing.
6. Does the equipment require regular maintenance?
Periodic inspection of seals, pressure gauges, safety valves, and piping connections is recommended. Keep the retort chamber clean and remove scale promptly. Water and air sources should be kept clean for long-term stable operation.
