Rapid cooling. Hygienic storage. Practical daily operation.
A horizontal, insulated direct-expansion cooling tank for rapid cooling and refrigerated storage of fresh milk. It is designed for dairy farms, milk collection centers and small dairy plants, combining a Copeland ZR47 compressor, gentle agitation and food-grade SUS304 milk-contact construction.
APPLICATIONS
Cool and store fresh milk directly after milking. The 4000L cooling tank provides a practical link between your milking system and the milk collection truck. It cools 1,000 litres of fresh milk from 35°C to 4°C in approximately 2.5 hours under normal ambient conditions and provides refrigerated storage until pickup.
Create a central cooling point for milk collected from nearby farms. The 4000L tank is suitable for cooperatives and regional milk collection centers, helping receive, cool and temporarily store fresh milk before it is transported to a dairy processor.
Keep raw milk properly cooled before processing begins. The 4000L tank can serve as a refrigerated buffer between milk receiving and production, allowing raw milk to be stored before it is transferred to pasteurization, cheese making or yogurt processing.
COOLING PERFORMANCE
Full 4,000 L Load
Heat is transferred directly through the tank cooling jacket, allowing the refrigeration system to remove heat from the milk efficiently during the cooling cycle.
4,000 L: 35°C → 4°C in approx. 2.5 hA low-speed agitator circulates the milk during cooling, helping reduce temperature differences within the tank and supporting more uniform cooling.
370 W · 36 rpmThe 50 mm polyurethane insulation helps reduce heat gain after the target temperature is reached, supporting refrigerated holding before milk transfer or pickup.

The inner tank and milk-contact parts are food-grade SUS304. The illustration is intended to show functional locations and construction layers. Final appearance, component arrangement and support details are subject to the confirmed production configuration and delivered equipment.
KEY COMPONENTS
Provides the refrigeration power required for rapid milk cooling.
Transfers heat through the tank cooling jacket to remove heat from the milk during the cooling cycle.
Circulates milk inside the tank, helping reduce temperature differences and support more uniform cooling.
Provides centralized temperature setting and monitoring during cooling and refrigerated holding.
DETAILS
Controls milk discharge from the tank. Milk-contact parts are made of SUS304, while the sanitary connection design supports disassembly, cleaning and routine maintenance.
Provides a practical sanitary connection for process piping and supports convenient disassembly, cleaning and pipe maintenance.
Provides tank ventilation and a sanitary connection point. The exact function and connection arrangement should be confirmed against the final configuration drawing.
CONFIGURATION & DOCUMENTS
The tank is prepared for CIP cleaning, but a complete external CIP station is not included in the standard supply. For more intensive operation, multiple tanks, or milk-processing projects, a mobile or centralized CIP solution can be considered separately.
CERTIFICATION
Milk Cooling and Hygienic Storage
The tank combines direct-expansion cooling with insulated refrigerated storage for fresh milk after milking. Its horizontal design is intended for dairy farms, milk collection centers, and small dairy plants.
Milk-contact surfaces are made from food-grade SUS304 stainless steel. Gentle agitation supports more even cooling during normal operation.
