GEA Filtration Ceramic MF Plant + HTS Plant

Skid mounted GEA Filtration ceramic Micro Filtration (MF) plant combined with a GEA Filtration High Temperature System (HTS) plant for bacteria and spore reduction in cheese milk. Previously running in a cheese plant in Europe.

First the milk has to be skimmed by a milk skimmer / separator (separator excluded), skim milk will enter the CMF unit, the skim milk will be filtrated, the bacterias and spores (retentate) will be sent to the HTS unit, the cream will be sent to the standardization device (excluded), after standardization the cream will be sent to the HTS unit, both (retentate and standardized cream) will be sterilized on high temperature in the HTS unit, after the HTS unit the skim milk, the sterilized retentate and standardized cream will be added together again. The whole set is designed for 12.500 m3/h with 4% fat input and an output of 12.262 m3/h with 3,3% fat (surpluss of cream of 0,238 m3/h).

The whole milk must not prior to this pretreatment, have been exposed to any kind of heat treatment such as thermization or pasteurization, as well, the milk must not have been exposed to homogenization.

Project number: 100118.

The line exist out out of 2 different sections:

• Section 01: Ceramic Micro Filtration plant, according flow sheet: 100118-11002.

Input capacity: 11.273 liter/h of skim milk.

Permeate output: 10.709 m3/h

Retentate output: 0,564 m3/h ("bacterias and spores" which will go afterwards to the HTS unit)

Process temperature: 52 °C

Year of manufacturing: 2004
