Rabljena predelovalna linija za majhne mlečne izdelke, 2000 l/h

Used processing plant for small dairy products, 2,000 l/h

Milk Reception and Initial Storage
The used processing line for small dairy products (2,000 L/h) starts with a milk intake unit consisting of two Lactofreeze tanks and a feed pump. Initially, operators transfer the raw milk into the tanks, where it remains chilled. This setup ensures thermal stability prior to processing. Additionally, this configuration minimizes microbial contamination while allowing a seamless transfer to the pasteurization stage.

Pasteurization and Separation
A plate heat exchanger with a retention section and auxiliary systems, all rated for 2,000 liters per hour, is used for pasteurization. Specifically, the pasteurizer rapidly heats the milk and holds it at a predefined temperature to eliminate pathogens. Afterwards, the GEA WESTFALIA separator with a capacity of 3,000 l/h takes over the cream separation. Simultaneously, the RANNIE homogenizer (1,000 L/h) reduces the size of fat globules, thereby enhancing emulsion stability and preventing cream separation.

Fermentation and Coagulation
After heat treatment, the milk proceeds to fermentation. Here, an insulated double-walled fermentation tank with a 1,000-liter capacity and planetary agitator is used. This ensures uniform bacterial activity and precise temperature control. In parallel, a 1,000-liter coagulation tank equipped with a planetary mixer initiates the coagulation process. Both tanks ensure optimal protein structuring for yogurt, cheese, and cultured cream products.

Cheese Processing and Whey Separation
Following coagulation, the used processing line for small dairy products (2,000 L/h) continues with cheese processing. The system consists of a 500-liter container with a drainage sieve and two curd drainage vats. Operators can therefore efficiently process large quantities of curd. Furthermore, these components simplify whey separation while ensuring compliance with hygiene standards. Their design also allows for easy cleaning and minimizes cross-contamination.

Packaging Operations
Once products are ready for packaging, the line integrates semi-automatic and automatic solutions. Initially, a semi-automatic filler doses pasteurized milk into 1-liter pouches. Subsequently, the yogurt cup filler automatically fills and seals 75 mm and 95 mm cups at up to 1,800 units per hour. The ETICAP (2004) rotary labelling machine applies both front and back self-adhesive labels to cylindrical cups, securing consistent label alignment and adhesion.

Date Coding, Temperature Control, and Final Packaging
In addition, a Videojet 1220 coder (2019) applies expiry dates to each product via conveyor. Further downstream, a vacuum packaging machine handles fresh and cheese portions. Thermal utilities include a solid fuel boiler with 115 to 150 kW output (2014) and dual transfer pumps. An ice water tank (5,000 L, 2014) and a chiller (2018) maintain constant temperatures across the entire processing line.
