Food-Grade SUS304 Stainless Steel Milk Cooling Tank

Efficient post-milking cooling is the most critical step in preserving dairy quality. The Weishu SUS304 milk cooling tank is engineered to rapidly reduce raw milk temperatures to an optimal storage state (4°C), effectively inhibiting bacterial growth and maintaining the integrity of fat globules. Designed for dairy farms, collection centers, and processing plants, this horizontal milk storage tank combines advanced refrigeration technology with sanitary structural engineering.

Temperature Control	Automatic Digital Microcomputer System

 

Features and Advantages

1. Superior Food-Grade Fabrication.
   Safety in the dairy industry starts with the substrate. Every sanitary stainless steel cooling tank manufactured by Weishu utilizes certified SUS304. Unlike lower-grade alternatives, our steel resists pitting and corrosion from lactic acid and harsh cleaning agents.
2. Seamless Welding & Surface Treatment.
   The internal tank walls undergo precision automatic plasma welding followed by rigorous polishing, achieving a surface roughness of Ra≤0.4µm. By eliminating microscopic pits and rough seams, we ensure there are no “dead zones” where bacteria can colonize, making your facility pass hygiene audits with ease.
3. High-Efficiency Direct Expansion Cooling.
   We utilize a laser-welded honeycomb evaporator jacket. This design maximizes the contact surface area between the refrigerant and the inner tank wall. This results in faster heat exchange rates compared to traditional pipe-coil designs, significantly reducing energy consumption.
4. Advanced Thermal Insulation.
   To maintain temperature stability, our tanks are injected with pressurized, CFC-free polyurethane foam. This high-density insulation ensures that even during power outages, the temperature rise of the milk is kept to less than 1°C over a 12-hour period.

Industrial Applications

The versatility of the Weishu horizontal milk storage tank makes it a staple in various liquid food sectors:

• Dairy Farming: Immediate cooling of raw milk directly from the milking parlor.
• Milk Collection Centers: Bulk storage and cooling before transport to large-scale processors.
• Beverage & Juice Production: Maintaining the freshness of temperature-sensitive ingredients.
• Small-scale Creameries: Ideal for artisanal cheese and yogurt production where milk quality is paramount.

Why Choose a Weishu Milk Cooling Tank?

In the precision-driven dairy industry, a cooling tank is more than a container—it’s the frontline of your quality control. While entry-level manufacturers often compromise on plate thickness or use refurbished compressors to cut costs, Weishu focuses on minimizing your Total Cost of Ownership (TCO) through industrial-grade builds.

• Audit-Proof Sanitary Design: Our engineering team prioritizes compliance. By eliminating internal 90-degree corners and utilizing specialized orbital welding, we ensure your facility breezes through stringent food safety audits (FDA/CE/ISO) without the risk of microbial “blind spots.”
• Built for Decades, Not Just Seasons: A Weishu tank is a 25-year investment. We use reinforced structural frames to prevent tank sagging under full loads and heavy-duty, high-torque agitation motors designed for continuous 24/7 operation.

FAQ

Q1: What is the typical cooling time for a Weishu milk cooling unit?
A: Typically, our systems are designed to cool milk from 35°C to 40°C within 2 to 2.5 hours, depending on the ambient temperature and the specific model capacity.

Q2: Can the tank be customized for specific site layouts?
A: Yes. While the horizontal milk storage tank is our most popular configuration for stability and ease of cleaning, Weishu offers vertical designs for facilities with limited floor space.
