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

Milk reception and initial storage
The used processing line for small dairy products with a capacity of 2,000 L/h begins with a milk reception unit, consisting of two Lactofreeze tanks and a receiving pump. Operators first direct the raw milk into the tanks, where it remains cooled. This setup ensures thermal stability before further processing. Additionally, this configuration minimizes microbial load while enabling a continuous transition to the pasteurization stage.

Pasteurization and separation
During the pasteurization phase, a plate heat exchanger with a retention section and auxiliary systems—each rated for 2,000 liters per hour—is utilized. Specifically, the pasteurizer rapidly heats the milk and holds it at a predefined temperature to eliminate pathogens. Afterwards, the GEA WESTFALIA separator with a throughput of 3,000 l/h separates the cream. Simultaneously, the RANNIE homogenizer (1,000 L/h) reduces fat globule size, thereby improving emulsion stability and preventing cream rise.

Fermentation and coagulation
Following thermal treatment, the milk proceeds to fermentation. Here, an insulated double-walled fermentation tank with a 1,000-liter capacity and planetary agitator is used, ensuring 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 provide optimal protein structuring for yoghurt, cheese, and cultured cream products.

Cheese processing and whey drainage
After coagulation, the used processing line for small dairy products, 2,000 L/h, continues with cheese processing. The system comprises a 500-liter vessel with a draining sieve and two cheese draining tables. This allows operators to efficiently process large quantities of curd. Furthermore, these components simplify whey separation while ensuring compliance with hygiene standards. Their design also supports easy cleaning and the prevention of cross-contamination.

Packaging operations
Once products are ready for packaging, the line incorporates both semi-automatic and automatic solutions. First, a semi-automatic filler doses pasteurized milk into 1-liter pouches. Then, the yoghurt cup filler automatically fills and seals 75 mm and 95 mm cups at up to 1,800 units per hour. The ETICAP rotary labeller (2004) applies front and rear self-adhesive labels to cylindrical cups, guaranteeing precise alignment and adhesion.

Date coding, thermal control, and final packaging
Additionally, a Videojet 1220 coder (2019) marks each product with expiry dates via conveyor. Further down the line, a vacuum packaging machine handles fresh and cheese portions. Thermal utilities include a solid fuel boiler rated at 115 to 150 kW (2014) with dual transfer pumps. An ice water tank (5,000 L, 2014) and a chiller (2018) maintain a constant temperature throughout the line, ensuring optimal product quality and process consistency.
