Automat / Rotomat: The Universal Full Water Immersion Retort for daily product,baby food,convenience food

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

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