Manufactured pasteurizer is of compact design on the supporting frame. It consists of:
The principle of operation of the juice pasteurizer:
The device collects the juice from the buffer tank and directs it to regeneration section (juice/juice), where it is preliminary heated up by the juice flowing from detention section. The juice after preheating process is driven to pasteurization section, where as a result of hot water heating reaches the presetted temperature in the pasteurization.
From the pasteurization section the product is directed to detention section, where it is held in presetted temperature during 30 seconds. Then it will reach the regeneration section and afterwards the cooling section, where it is cooled down to presetted exit temperature and it is lead to process tank.
Both the pasteurization process as well as cleaning and preparation for production (system disinfection) are being supervised and controlled by a dedicated system according to user input recipes.
Additionally, the program stores and archives all relevant user parameters and generates reports from washing and production, which are required for food safety management system.
The control is performed by a control cabinet mounted on the supporting structure of the device. The cabinet made of material 1.4301 of protection IP65 is equipped with a touch-control panel type Touch-Screen 6 " and programmable controller Siemens S7 300.

Glossary:
Pasteurization is a type of thermal processing of food products, aimed at the destruction and suppression of microorganisms’ development. The inactivation of vegetative forms of microorganisms can extend the life shelf while preserving food taste and nutritional value.
Direct juice (eng. NFC – Not From Concentrate), obtained from the fruit by squeezing, pressing or centrifugation, pasteurized or unpasteurized (unpasteurized juices require refrigeration conditions of transport and storage).
