Full Water Immersion Counter Pressure Retort Concept

Energy contained in the storage vessel allows for extremely fast temperature come-up-time.

Water envelops the containers - even temperature penetration into the product from all sides.

Optimized water circulation system guarantees homogenous temperature distribution. Buoyancy in full water immersion relieves sensible containers as semi-rigid trays, pouches etc. Counter pressure control with steam in the storage vessel avoids pressure peaks and minimizes stress to packaging material.

Containers are at no process phase in contact with air - oxidation of products is securely excluded. Even, gentle but nevertheless fast cooling avoids thermal shock and post-sterilisation cooking effect.

High temperatures, transferred swiftly into the product, ensure that the required lethality effect (F-value) is obtained as fast as possible.

» The main advantages of the Full Water Immersion system.

» Forced convection due to rotary operation accelerates the heat transfer to the coldest spot in the containers, even with products of higher viscosity.

» Short process times preserve natural quality, vitamins and nutritional values.

» Agitation of the product during heating prevents burning on the container walls.

» Rotation with an intensely mixed process water environment with its optimal heat transfer ensures the HTST
   (high temperature-short time) processing of most Products.
