Direct Steam Retort

Product Details

Product Description

Innovaster Direct Steam Retort will be used to process rigid containers such as cans. Retort chamber should be saturated at the beginning for air is considered an insulating medium and all air will be evacuated from the retort by flooding the vessel with steam and allowing the air to escape through vent valves. There is no overpressure during the sterilization phases of this process,and air-overpressure will be applied during the cooling steps to prevent container deformation.

 

Working Principle

In the beginning, steam is injected into the retort vessel through the steam spreader pipes, and air escape through vent valves. When both time and temperature conditions established in the process are met simultaneously, the process advance to come-up phase.In the whole come-up and sterilization phase, retort vessel is filled with saturated steam without any residual air in case of any uneven heat distribution and insufficient sterilization. The bleeders must be open for the entire vent, come-up, cooking step so that the steam can form convection to ensure the temperature uniformity.

 

In a Saturated Steam process these steps are:    

1. Come Up Vent Open  

2. Come Up Vent Closed    

3. Cook (A Sterilization Step)    

4. Pressure Cool Fill    

5. Pressure Cool    

6. Atmospheric Cool    

7. Drain
