3000L SS304 Horizontal Milk Cooling Tank Product Introduction
The 3000L SS304 Horizontal Milk Cooling Tank is an advanced milk cooling and storage system designed for modern dairy processing operations. This milk cooling tank integrates refrigeration, insulation, and agitation into one efficient unit, ensuring rapid cooling, hygienic storage, and stable milk quality.
This equipment is widely used in dairy farms, milk collection centers, and food processing plants, helping reduce bacterial growth, extend milk freshness, and improve overall production efficiency. With durable SS304 construction and energy-efficient cooling technology, it is an ideal solution for small to medium-scale dairy businesses seeking reliable performance at a competitive factory price.

System Overview
- Integrated milk cooling and storage system combining refrigeration, insulation, and agitation in one compact unit
- Designed for rapid cooling from fresh milk temperature to 4°C or lower
- Equipped with high-efficiency compressor system for stable cooling performance
- Inner tank made of SS304 stainless steel ensuring food-grade hygiene standards
- Horizontal structure design for easy installation, transport, and maintenance
- Suitable for continuous dairy processing and batch milk storage operations
Production Process Description
- Fresh milk is directly pumped into the milk cooling tank after collection
- Agitator system ensures uniform temperature distribution and prevents cream separation
- Cooling system rapidly reduces milk temperature to safe storage level (≤4°C)
- Insulation layer maintains low temperature with minimal energy consumption
- Milk is stored hygienically until further processing (pasteurization, packaging, etc.)
Why This System Is Designed This Way
- Rapid cooling reduces bacterial growth and preserves milk quality
- Horizontal design improves heat exchange efficiency and structural stability
- Agitation system prevents milk stratification and ensures uniform cooling
- Integrated system reduces footprint and simplifies installation
- SS304 material ensures corrosion resistance and long service life
- Energy-efficient refrigeration lowers operational costs
