Tetra Alfast®Plus
Direct In-line standardisation

Tetra Alfast Plus is designed for automatic in-line standardisation
of the fat, SNF and protein content in milk and cream direct after
milk separation for dairy products including; low and high fat
market milk, market cream, flavoured milk, cream for butter
making, milk for fermented products and power production,
cheese milk, whey, ice-cream mix, formulated products and
functional foods.

Working Principle
By continuously controlling the back pressure of the separator
cream outlet in a Cascade Control System, an accurate fat content
is achieved, regardless of variations in the raw milk fat content.
The raw milk is separated in the separator where the skim milk
pressure is kept constant by a constant pressure-modulating

valve. A flow transmitter measures the cream flow from the
separator and the fat content is calculated from a temperature
compensating density transmitter. Another flow transmitter measures the flow of standardised milk.
On receiving signals from the transmitters, the computer in the
control panel calculates the fat content, in relation to set points
and flow rates, and then transmits control signals to the cream flow
modulating valve, thereby controlling the fat content, whenever
required.
All models have a surplus cream line that is used for regulating the
flow rate of remix cream into the skim milk line, thereby
standardising the milk
