HRS Thermblock AS Series: Packaged annular-space pasteurizer and sterilizer

In this series, the sterilizer is composed of concentric tubes heat exchangers, or annular-space heat exchangers of HRS AS Series that are the most suitable heat exchangers range for high viscosity products without particulates. Product flows in the central annular space, while the heating or cooling media passes both through the internal and external jacket.

Therm Block AS series HRS FUNKE HRS Thermblock AS Series is a solution for thermal treatment for pasteurising and sterilization of food products, with high viscosity in the food industry for aseptic filling processes or any other filling/packaging method. The sterilizer is a single and compact group which is operated from a single control panel. Due to its design it is an easy to operate equipment, of high flexibility and reliable productivity.

HRS Thermblock AS sterilizers allow the adjustment of heating-holding-cooling cycle of the product in the way that it best suits your needs. It can also work with HTST (High Temperature Short Time) method, in other words, it is able to bring the product under high temperatures for a short time. In this way you achieve a highly efficient process, which allows you to optimise the sterilization process, ensuring that you achieve all the desired effects of it and, at the same time, minimise the undesirable side-effects (organoleptic and/or nutritive losses).

The sterilizer can include a high pressure piston volumetric pump with frequency converter, suitable for high viscosity products such as tomato paste or some purees. Working pressures up to 180 bar can be reached.

With pressures up to 40 bar or products with particulates, HRS has developed the HRS BP Series piston pump. This pump is manufactured in stainless steel, without plastic parts, and allows a temperature design of 120ºC, CIP cleaning, working in aseptic process, etc.

Features a buffer tank for product storage and deaeration, for removing the air, thus ensuring the efficiency of the thermal treatment.
Volumetric pump extracting product from the feed tank to the piston pump.
Piston volumetric pump with frequency converter.
Suitable for high pressure designs.
Heating media with superheated water and recirculation group.
On/off high pressure valve group.
Sterilization stage is made with overheated sterile water.
Autonomous and automatic CIP system grants high level of hygiene.
Completely made on stainless steel.
Features an autodiagnostics PLC which continually monitors the operating conditions, which grants a high security and reliability in the whole process.
All equipments conforming to the requirements of European Pressure Equipment Directive 97/23/EC and also for Food and Drugs Administration (FDA & EHDGE).
