China Dairy Storage Tank Manufacturer — Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel)
Engineering Hygienic, High-Performance Storage Solutions for the Global Dairy Industry
Milk and dairy products are among the most widely consumed foods worldwide. From fresh milk to yogurt, cheese, butter, ice cream, and powdered dairy goods, dairy production depends on precision, hygiene, and consistent temperature control throughout the supply chain — from farm collection to processing, packaging, and distribution.
At the heart of this complex system lies a critical element: dairy storage tanks. These tanks preserve the quality, safety, and integrity of dairy products, ensuring compliance with stringent food-grade standards and protecting consumer health.
As dairy markets expand and food safety regulations strengthen around the world, manufacturers and processors increasingly seek storage solutions that combine sanitary design, corrosion resistance, temperature control, engineered reliability, and global compliance. This is where Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) delivers significant value as a leading China dairy storage tank manufacturer — trusted by global dairy enterprises across more than 100 countries.
1. What Are Dairy Storage Tanks and Why Do They Matter?
1.1 Definition and Core Purpose
A dairy storage tank is a vessel designed to store dairy liquids safely under controlled conditions. These tanks may be used to hold:
Raw milk at collection points (farms or receiving stations)
Processed milk before or after pasteurization
Dairy product intermediates during production (e.g., cream, whey)
Finished dairy liquids before packaging
Buffer storage for processing lines
Beyond simple containment, dairy storage tanks have three essential functions:
Maintain product quality and freshness
Prevent microbial contamination
Support precise temperature control and hygiene
1.2 The Challenge of Dairy Liquids
Dairy liquids are:
Perishable, especially raw milk
Susceptible to microbial growth
Sensitive to temperature and environmental contamination
Subject to strict food safety regulation
Without proper storage, dairy products can deteriorate rapidly, leading to financial loss, product recalls, regulatory penalties, and public health risks.
A well-engineered dairy storage tank minimizes these risks and enables dairy producers to meet HACCP, ISO 22000, FSMA, European Hygienic Engineering & Design Group (EHEDG) and other regulatory standards.

3. Core Technologies Behind Dairy Storage Tanks
Dairy storage tanks must fulfill stringent requirements for hygiene, corrosion resistance, temperature control, cleanability, and reliability. Center Enamel incorporates advanced technologies and materials to ensure excellence.
3.1 Stainless Steel Material Selection
Stainless steel is the cornerstone of dairy storage tank manufacturing. Center Enamel typically uses food-grade stainless steel (304 and 316L grades) because:
It offers excellent corrosion resistance
It supports sanitary cleaning
It withstands CIP (Clean-In-Place) systems
It resists degradation in acidic or alkaline sanitizing environments
It maintains structural integrity under thermal cycles
316L stainless steel is often selected for more aggressive sanitary environments or for products requiring especially high corrosion resistance.
3.2 Hygienic Interior Surface and Sanitary Welding
Sanitary design mandates that internal surfaces must be:
Smooth and non-porous
Without crevices or dead zones
Polished to precise surface finishes
Finished with sanitary welds (using TIG or equivalent methods)
Center Enamel’s fabrication process incorporates:
Internal polishing to specified Ra values
Precision sanitary welds
Sanitary fittings (Tri-Clamp, DIN, SMS)
Seamless internal geometry to minimize bacterial adhesion
3.3 Temperature Control and Refrigeration Integration
Temperature management is crucial in dairy storage:
Raw milk must often be rapidly cooled to below 4°C
Process storage may require precise temperature stability
Cooling systems must integrate with tank designs
Center Enamel supports tanks configured with:
Refrigeration jackets
Insulated hulls
Heat exchangers or cooling coils
Automated temperature control systems
Sensor integrations for monitoring
These features help maintain consistent cold-chain conditions within the dairy tank.
3.4 Sanitary Connections and Clean-In-Place (CIP) Systems
Efficient and hygienic cleaning is non-negotiable. Center Enamel designs dairy tanks to support:
CIP spray balls
Sanitary manways
Valves and fittings suited for food service
Drain ports optimized for complete drainage
Automation-ready instrumentation
Together, these systems reduce manual cleaning, lower contamination risk, and support rapid turnover between batches.
3.5 Food Safety Certification Compliance
Dairy tanks engineered by Center Enamel support global food safety compliance frameworks such as:
ISO 22000 Food Safety Management System
Hazard Analysis and Critical Control Points (HACCP)
European Hygienic Engineering & Design Group (EHEDG) guidelines
U.S. FDA and NSF food contact standards
National dairy authority regulations in local markets
These standards guide material selection, surface finish requirements, and manufacturing practices to ensure safe dairy storage performance.
