High Viscosity Tube-in-tube Sterilizer Line is suitable for high-viscosity products (tomato concentrate, fruit puree concentrate) and small-volume products (fruit pulp, sauces with chunks). It adopts with tube-in-tube design and tube-in-tube heat exchange technology.

The product circulates heat through a concentric tube heat exchanger, which consists of four tubes of gradually decreasing diameter, placed one inside the other. Each module consists of four concentric tubes forming three chambers, with exchange water flowing in the outer and inner chambers and product flowing in the middle chamber. Product flows within the central annular space while heating or cooling fluid circulates counter currents to the product inside the inner and outer jackets. Therefore, the product flows through the ring section and is heated both internally and externally.

-High Viscosity Tube-in-tube Sterilizer Line is equipped with a superheated water preparation and circulation system, using tube bundles and centrifugal pumps, and maintenance equipment for the cooling part, including a cleaning device for the cooling water-wetted surface.

-The mixer (baffle) makes the processed product highly uniform in temperature and minimizes the pressure drop in the circuit. This solution allows better heat penetration into the product, with a larger contact area and shorter residence time, resulting in even, fast processing.

-The cooling tubes are equipped with in-line vapor barriers and controlled by Pt100 probes.

-High Viscosity Tube-in-tube Sterilizer Line is equipped with special flanges and barrier vapor chambers with O-ring gaskets. The modules can be opened for inspection and connected in pairs via a 180° curve that is flanged on one side and welded on the other.

-All surfaces in contact with the product are mirror-polished.

-Product piping is made of AISI 316 and equipped with equipment to control the various stages of operation, CIP product cleaning and SIP Sterilization.

-The Germany Siemens Control System controls the motors as well as the management and control of variables and various cycles via Germany Siemens PLC and touch screen panels.
