Microfiltration Plant for Bacteria Removal (Ceramic Membranes)

Highlights and application:
Microfiltration (MF) is a well proven technology offering a wide range of opportunities for modern dairy processing. The main advantages of the MF plant are as follows:
-Improved product quality and shelf life
-Reduced product loss
-Nitrate free cheese making
-State of the art membrane technology
-Integrated high temperature treatment plant for cream and retentate
-Flexible and modular design
Typical applications of MF Ceramic plants within the
Dairy Industry are as follows:
-Bacteria and spore removal from skim milk, for Bacteria free cheese making
-Bacteria and spore removal from skim milk, for improved and premium quality ESL milk products
-Bacteria and spore removal from whey, for improved
quality of whey The MF plant consists of cross flow filtration loops in which the calibrated ceramic membranes are the key components. The MF plants are usually utilized in the following sectors within the Dairy industry:
-Cheese Manufacturing
-ESL/UHT Manufacturing
The main advantages of our MF plants are as follows:
-Our system ensure minimum 99.5% bacteria removal
rate
-Our system uses a HTT section where retentate and cream are mixed and heat treated up to 120C and then
combined with the main stream. Hence there will be no loss on our system.

Operation

The MF plant is designed fully automatic and from HMI all of the operation parameters and program sequences can be controlled and monitored. Also, all of the necessary process alarms are already incorporated into the program. The operation presence is only required during operation as surveillance The following process
sequences are realized automatically:
-Production
-Circulation
-Emptying
-CIP
-Shut down/Stop plant

Options

MF plant can include the following options:
-Automatic CIP dosing unit
-UPS (Uninterrupted Power Supply)
-Air cooler for Control Panel

Components

MF Plant usually includes the following components:
-Closed balance tank including level transmitter and CIP device
-Valve manifold including set of change over valves and automatic butterfly valves
-Feed pressure system including feed pump, flow transmitter and in line filter
-MF Ceramic modules
-Regulating valves and instruments for controlling of process flow

-Equipment for flush water including shut off valves and adjustment valves
-Equipment for steam and cooling water including shut
-Set of change over valves
-Set of pipes and fittings
-Set of shut off valves for water balance tank
-Set of instruments such as temperature and pressure transmitters.
-Stainless steel control panel including PLC, HMI, power supply,
solenoid valves, motor starters, MCC etc.
-All of the MF plants are tested in our factory before delivery
