Tetra Pak Tetra Alcross
Ultrafiltration plant for Fermented products
3 Main items:
1) Thermisation unit
2) Ultra filtration UF for fermented milk
3) Cooler and Silo.
The line is used to make Quark but designed to make mascarpone.
The Thermisation and Ultrafiltration unit are also suitable to make other fermented and concentrated dairy products like: Skyr, Mascarpone and Double Cream cheese.
Key data:
-input: 3.500 - 5.000ltr/h Fermented skim milk, Full fatt milk or enriched products.
-Concentration factor: 1.8-2.5
1) Thermisation unit
Complete skid mounted thermisation unit.
Flow rate : 3.500 up to 5.000ltr (depending on product).
Make : Tetra pack
Model : TetraTherm
Stock number : STN16309
Function: Thermisation of fermented products.
Temperature cycle:
Input: 21-30 °C (incubation temperature) -> recuperation (permeate cooler) -> thermisation 55/60°c or pasteurisation at 72/95 °C -> holding -> out to Ultra Filtration at approx. 45 °C.
Complete unit including:

2) Ultrafiltration unit
Manufacturer : Tetra Pak
Type : Tetra Alcross US P&F
Serial number : T5845810096
Year : 2010
Capacity : input up to 5.300ltr/h
Stock number : STN16310
Description :
Concentrates a yoghurt or a fermented milk to achieve the desired composition and texture.
The UF splits the product in Rentate and Permeate.
The Retentate is the endproduct and is the Protein and Fatt (if included) concentrated.
The advantage of this design UF (compared to Spiral wound UF and separator) is it is suitable for Fermented products with and without Fatt and all proteins are concentrated (also the whey proteins)
This leads to high pressures in the system and Filtration can only be achieved with a Plate and Frame filtration with flat FR60pp filters and Rotary piston circulation pumps.
Some example productions:
input: skim milk 9% TS -> output approx. 16% TS (Skyr).
Input: input 20% TS incl fatt -> Output Cream cheese or mascarpone
Input: Ferm. skim milk pre-concentrated up to 12% TS -> output up to 18% TS (Quark)
The limiting factor is the Permeate out flux
Approx. Permeate per stage:
Stage 1) 1100-1755ltr/h 13.5m2 filters
stage 2) 675/1170ltr/h 9m2 filters
stage 3) 320/585ltr/h 4.5m2 filters
stage 4) 300/585ltr/h 4.5m2 filters 15bar.
Complete skid mounted.
