UHT Equipment

Tuchenhagen Dairy System's UHT (Ultra-High-Temperature) plants are reliable aseptic processing of drinks, such as the juice, tea and milk. Production safety, outstanding product quality and efficiency are all characteristics of progressive engineering.

Heat treatments are used to destroy all or some of the microorganisms present in the raw product. Furthermore more or less complete inactivation of enzymes occurs, depending on the temperature and treatment time. How to retain as many as possible of the good organoleptic and nutritive properties of the raw material, GEA Tuchenhagen Dairy System has been devoting to research and developing the heat method for many years.

Flexible Solutions

GEA Tuchenhagen Dairy System's UHT plant was the first tubular system with a multi-tube heat exchanger with straight tubes and brought a great new opinion in this area. The UHT technology offers the ideal pre-requisites for a plant to meet prevailing product requirements. Short heating and cooling phases ensure excellent product quality.

GEA Tuchenhagen Dairy System's UHT plant uses the VARITUBE for the heat treatment, which is a straight tube heat exchanger with one or more inner tubes situated in a shell. A completely “welded” unit as well as a flexible design is available. The inner tubes can be either plain or corrugated. Different diameters of the product tubes and the shell tubes can be selected, so according to the requirements, the most suitable type can be chosen from a wide range of heat ex-changers.

Construction Character

All parts of THE in contact with the product are made of material no.1.4571 (equivalent to AISI 316 Ti). According to different capacity of the plant and different type of product, there is different installation of internal product tubes.

The gaskets are only used between the THE and the bend. It is very easy to disassemble the bend to inspect the internal tube.

Most heat exchanges are built 3,000 mm long.
