Tetra Alfast® Plus Direct In-line standardization - 1

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
