Bactocatch Micro Filtration Unit (MF) with HTT Section - Tetra Pak Tetra Allcross MB 1x M74 / 1x M19 + C6-SM

Complete skid-mounted Tetra Pak Tetra Alcross Bactocatch MB Microfiltration (MF) plant, type 1 x M74 / 1 x M19, manufactured in 2011 and specifically designed for hygienic dairy processing applications.

The Tetra Alcross Bactocatch system is designed for the highly efficient removal of bacteria and bacterial spores from milk by means of ceramic membrane microfiltration combined with High Temperature Treatment (HTT) of the cream fraction. The process can achieve a bacterial and spore reduction of up to 99.9999%, depending on the product and operating conditions.

The fully skid-mounted installation is designed for continuous microfiltration of milk and is suitable for applications including the reduction and removal of bacteria and spores from skim milk, cheese milk and ESL milk, as well as protein fractionation. The plant was previously operated for the treatment of skim milk for the reduction and removal of bacteria and spores.

The MF section is equipped with Pall Corporation ceramic GP (Gradient Permeability) microfiltration membranes with a nominal pore size of 1.4 µm. The membrane system is designed for a feed capacity of approximately 7.535 litres/hour. Under the specified operating conditions, the system produces approximately 75 litres/hour of retentate and 7.460 litres/hour of permeate, corresponding to a concentration factor (CF) of approximately 100.

The installation is designed for approximately 9 hours of operation between CIP cycles, with an average filtration flux of approximately 229 l/(m²·h) at 50 °C.

Installed power: ± 85 kW - 400 V - 50 Hz

The complete installation is supplied as a stainless-steel skid-mounted processing system and includes the membrane filtration section, product and CIP piping, hygienic valves, instrumentation, pumps, control equipment and associated process utilities.

The Cream High Temperature Treatment (HTT) section consists of a separate skid-mounted cream pasteurisation unit, equipped with an Alfa Laval C6-SM plate heat exchanger, serial number 30107-33658, manufactured in 2011. The cream pasteuriser comprises 5 heat-treatment sections, centrifugal pumps, hygienic valves, balance/level tank, indirect hot-water heating system and interconnecting stainless-steel process piping.

A highly attractive and complete Tetra Pak membrane filtration installation for dairy processors looking for a proven and compact MF solution for skim milk treatment, cheese milk processing, bacterial and spore reduction, ESL applications and/or protein fractionation.

The complete skid-mounted configuration offers a practical solution for integration into an existing dairy processing facility and provides a well-proven Tetra Pak technology for hygienic membrane filtration applications.
