Understanding the Importance of Still Retorts with Overpressure in Canned Food Processing


Canned food has become a staple in many households worldwide, providing a convenient and long-lasting way to preserve food. However, the process of canning food is complex and involves several critical steps to ensure food safety and quality. One of these steps is the use of still retorts with overpressure.


The term “overpressure” refers to the pressure supplied to a retort in excess of that exerted by the heating medium at a given process temperature. Air or additional steam is introduced during the processing cycle to provide the overpressure. Overpressure during processing is required to maintain the integrity of certain containers that have a limited resistance to internal pressure.


Innovaster is a leading manufacturer of still retorts with overpressure, known for their high-quality and reliability. Their retorts are designed to meet industry standards and requirements, ensuring that the canned food produced is safe and of high quality.

A variety of retort types that can be designed by Innovaster to provide overpressure during processing, retorts varies from:

1. Water Immersion Retorts- containers are totally immersed in water

2. Water Cascade Retorts- water that cascades over the containers

3. Water Spray Retorts- combination of water sprays and steam/air

4. Steam Air Retorts- Steam air mixture


These retorts are equipped with various controls and alarms necessary to monitor the critical factors. Proper installation and operation of each retort is essential to achieve satisfactory processing results.


One of the key benefits of using Innovaster still retorts is that they are highly customizable and can be tailored to meet the specific needs of the food processing plant. This means that food processors can choose the right size and configuration of the retort to fit their production needs, ensuring that they can efficiently and effectively process their canned food.


Another advantage of Innovaster still retorts is their energy efficiency. The retorts are designed to use minimal energy while still achieving the required temperature and pressure levels. This helps to reduce energy costs and minimize the environmental impact of the food processing plant.


Still retorts with overpressure play a critical role in canned food processing, ensuring that the food produced is safe and of high quality. Innovaster is a reputable and reliable manufacturer of still retorts that are designed to meet industry standards and requirements, providing food processors with a range of benefits that help to improve their production efficiency and effectiveness.
