Full water immersion counterpressure retort concept

• Energy contained in the storage vessel allows for an extremely short temperature come-up-time.
• Water envelops the containers - even temperature penetration into the product from all sides.
• Optimised water circulation system guarantees homogenous temperature distribution.
• Buoyancy in full water immersion relieves sensible containers as semi-rigid trays, pouches etc.
• Counterpressure control with steam in the storage vessel avoids pressure peaks and minimises 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.

Rotation:

• 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.
• End-over-end rotation in an intensely mixed process water environment with its optimal heat transfer ensures the HTST (high temperature - short time) processing of most products.

Variants for all requirements

Various as our customer's requirements regarding capacity and sterilisation process - our range of full water immersion retorts: from the 2-cage autoclave for small batches of high quality "delicatessen" up to large capacity retorts for vegetable products in pouches.

Economic and clean

The use of heat exchangers significantly simplifies the incorporation of the retorts into energy and water recovery systems:

• Indirect heating = recovery of condensate
• Indirect cooling = multiple use of cooling water, cooling in a sterile environment
