How to produce more – without increasing your input

By increasing cream concentration, you can produce millions of kilograms more standardized milk – or skim milk – from the same input. This big step forward can be achieved without affecting skimming efficiency.

Would you like to be able to produce more from the same amount of raw material? This is what the AirTight design of Tetra Pak separators enables you to do. Because the cream concentration can be increased, you can produce more and therefore earn more money from your existing input.

As an example, by going from 40% cream fat to 44%, a dairy would be able to increase standardized milk production by 2,590,000kg per year, or 2,870,000kg for skimmed milk. This is based on 4% raw milk, with the separator running 7,000 hours per year, and with 60,000kg per hour standardizing and 45,000kg per hour skimming.

“If you are getting €0.10 per litre, that is about €250,000 in your pocket, essentially without increasing your input – just by owning the right separator,” says Jörgen Cederhag, commercial product manager at Tetra Pak.

Even making a smaller increase – from 40% to 42% – has a considerable effect. “You get an increase in production that is more than a million kilograms per year, which still equals a lot of money,” says Cederhag. “And still it doesn’t mean you have to increase your input.”

What makes this possible is Tetra Pak’s patented AirTight design. The combination of the cream being extracted from the centre of the bowl, plus the absence of air because the separator is hermetically sealed, gives higher cream concentration with maintained skimming efficiency.

As an example, if you produce anhydrous milk fat (AMF), Tetra Pak separators can handle up to 60% cream fat without losing skimming efficiency – a unique feat in the separator market. “You get more skim milk and less butter milk in your AMF line, which creates more value for you,” says Cederhag. “We haven’t changed anything here – it is the same input, and we are just diverting the flows in a different way. By changing the mass balance in your production like this, you get more value from your input.”
