Product DescriptionProduct IntroductionThe milk cooling tank (also known as a refrigerated milk storage tank or direct-cooling milk tank) is a core piece of equipment in dairy collection stations, farms, and small-scale dairy plants. It is used for rapid cooling and short-term storage of freshly extracted raw cow's (or goat's) milk, inhibiting microbial growth and preserving the milk's freshness and physicochemical properties to the greatest extent. Its core function is to directly cool the milk inside the tank via a refrigeration system, enabling rapid temperature reduction and constant-temperature storage. Main Structure: Inner Tank: Cylindrical/conical-bottom stainless steel container for holding milk. Evaporation Jacket: Miller plate jacket tightly welded to the outer wall of the inner tank, where refrigerant flows to absorb heat from the milk. Insulation Layer: High-pressure foamed polyurethane filled between the inner tank and outer tank wall. Outer Shell: 304 stainless steel cladding to protect the insulation layer. Mixing System: Top-mounted drive motor + gear reducer + stirring shaft and paddles extending into the tank. Refrigeration Unit: Compressor, air-cooled condenser, liquid receiver, dryer filter, expansion valve, and evaporator (i.e., the jacket). Control Panel: Integrated control system, electrical components, and display panel. Accessories: Manhole cover, thermometer port, level sensor port, cleaning spray ball, milk inlet/outlet, drain port, and breather filter (dustproof and breathable). Rapid & Deep Cooling Uniform Mixing & Temperature Stability High-Efficiency InsulationPrinciple: Adopting High-power, high-efficiency compressor unit (semi-hermetic piston type) and Large-area evaporator jacket (Miller plate jacket welded to the inner tank wall) Effects: Cools hot milk ( around 35℃) to safe storage temperature (≤4℃) in 2-4 hours, far faster than traditional water bath cooling. Significantly inhibits bacterial growth (reduces total bacterial count), extending natural freshness (up to 48-72 hours) and ensuring high-quality raw material for further processing (pasteurization, UHT, etc.). Principle:Equipped with variable-frequency agitator (vertical paddle/anchor-type), operating intermittently or at low speed. Effects: Prevents fat separation, ensuring homogeneous milk consistency. Eliminates temperature differences to ensure consistent milk temperature inside the tank (temperature difference ≤±0.5℃). Low-shear design avoids damaging milk fat globules. Principle: High-density polyurethane foam insulation (50mm thickness, ≥95% closed-cell rate) between inner and outer walls. Effect: Excellent static insulation performance with a milk temperature rise ≤1-2℃/24h (empty tank test), significantly reducing cooling energy consumption. Fully Automated Intelligent Control Food-Grade Hygienic Design Reliability, Durability & Safety Principle: Integrated microcomputer controller/PLC, with temperature sensors, level gauge, and timer. Functions: Auto start/stop cooling:Stops at target temperature (e.g., 4℃), restarts when temperature rises. Programmable mixing:Adjustable intervals (e.g., 5 min every 30 min) and speed. Level monitoring & protection:Prevents dry-running (low-level shutdown) or overflow (high-level alarm). Self-diagnosis & alarms:Detects refrigerant shortage, overpressure, overload, etc. Materials:The inner of tank and all milk-contact parts use 304/316L stainless steel , mirror-polished (Ra ≤0.8μm), no dead corners, easy to clean. Fully Enclosed Structure: the top manhole with a quick-open sanitary lid and sealing ring. CIP cleaning compatible:Standard spray ball ensures that there are no cleaning dead corners on the top, wall, or bottom of the tank. Tilted base design:Tank legs can be adjusted to tilt, and the discharge port has a slanted groove and elbow pipe to thoroughly drain residual milk and cleaning water. Refrigeration System:High-quality compressors , condensers, expansion valves – stable & efficient operation. Safety Features: Pressure relief valve & safety devices. Mechanical seal with oil tray:Prevents lubricant contamination. Electrical protection:Overload, phase loss, short-circuit, and grounding protection.
