Construction and installation of standard cold storage for milk preservation

Milk is an extremely sensitive food; a small deviation in temperature is enough for bacteria to take hold and spoil its nutritional value. Investing in an ISO-standard cold storage milk is therefore vital for food businesses. At Tan LongWe offer solutions. cold storage design in depth, incorporating humidity control technology and a temperature held steadily between 2°C and 5°C. With European imported refrigeration compressor systems, our solution not only keeps milk tasting fresh but optimises the business's running costs.

What is a milk cold store?

Technically speaking, cold storage milk is a purpose-designed storage system using industrial refrigeration equipment to hold an ideal temperature (normally 2°C to 5°C). Its core objective is absolute control of the environment, suppressing microbial growth so that milk and dairy products retain their nutritional value and quality.

The investment cold storage design for the dairy industry plays a vital role, because milk is an extremely “sensitive” food. Stored at the wrong or an unstable temperature, the protein and fat structures in milk break down, and the milk turns sour, curdles or becomes contaminated within a short time.

Tân Long's industrial cold storage systems are currently used widely at:

• Processing plants: Storing raw milk after collection and finished product before distribution.
• Distribution networks and dealers: Keeping yoghurt, cream and cheese in ideal conditions.
• Small businesses and dairy farms: A solution for storing milk in quantity, giving control over the timing of transport and optimising profit.

With the support of imported refrigeration compressor and intelligent automatic controls, Tân Long's milk storage solution gives businesses complete confidence in their product quality from production through to the consumer.

The detailed construction of a standard Tân Long milk cold store

To ensure 24/7 performance and keep milk at its best, a cold storage milk needs to be built from 4 matched technical components meeting strict food safety standards:

The insulation system (envelope and doors)

This is the key component in holding a stable temperature and preventing heat loss to the environment.

• Walls and ceiling: Use the panels Insulated panel in high-density polyurethane (PU) or PIR, at a standard thickness of 75 mm – 150 mm. The envelope is clad in premium steel or stainless steel, corrosion-resistant and with excellent thermal performance.
• Warehouse door: System cold storage door (sliding or hinged) are fitted with tight rubber gaskets and frame heaters to prevent condensation, ensuring the cold is completely contained.
• Warehouse floor: Designed to carry load, lined with stainless steel or ribbed aluminium for slip resistance, making goods handling safe and cleaning easy.

The industrial refrigeration system

This is the “heart” of the system, keeping the milk storage temperature steady within the 2°C – 4°C range.

• Compressor unit: Tân Long favours refrigeration compressor imported from reputable brands such as Bitzer, Copeland and Danfoss, to maximise performance and save electricity.
• Condenser: System industrial refrigeration are sized precisely to ensure even air circulation, avoiding the uneven temperatures that spoil milk.
• Refrigerant: Using purpose-made refrigerants (R404A, R134A) meeting international standards, safe for food and environmentally friendly.

Automatic control and monitoring

To run a cold storage milk methodically, an intelligent control cabinet system is essential.

• Central controller: Incorporating PLC/SCADA technology, allowing the temperature to be set and adjusted to the degree.
• Intelligent sensors: Continuously monitor the temperature and humidity inside. The system automatically triggers an alarm or sends a smartphone notification if the temperature moves outside the permitted range, so technical risks can be dealt with promptly.

A stable electrical supply and standby power

Because milk spoils as soon as the temperature changes, the electrical system needs designing for continuity.

• Power distribution panel: Fitted with phase-loss and overcurrent protection to protect the compressor system.
• Standby power: Integrating a generator or a UPS is the best solution, and one Tan Long always recommends to clients. It ensures that even during a mains power failure, storage in the industrial cold storage continues uninterrupted, protecting the business's economic value.

The operating principle of a milk cold store built to technical standard

The operating principle of a cold storage milk at Tân Long is based on a closed thermodynamic cycle, optimised for the extremely sensitive characteristics of fresh milk and dairy products. The central objective is to lower the temperature rapidly and hold both temperature and humidity absolutely stable, to suppress the bacteria and enzymes that cause spoilage.

Specifically, the refrigeration compressor system acts as the “heart”, compressing the refrigerant to high pressure, which is then cooled at the condenser before passing through the expansion valve to drop to the required temperature. That cold flow is then carried to the industrial refrigeration mounted inside the store.

There, high-efficiency fans create forced convection, circulating the cold air evenly to every position in the storage space. Thanks to this intelligent air distribution, all the milk inside the industrial cold storage is covered by a uniform temperature, eliminating technical “hot spots” entirely, so the milk keeps its full flavour and nutritional value throughout its time in store.

Why should a business invest in a milk cold store?

In the food supply chain, a cold storage milk is not just an ordinary storage solution but a vital factor in raising competitiveness and protecting brand credibility. The key benefits it delivers are:

• Preserving nutritional value in full: Milk is very high in protein, vitamins and minerals, but extremely sensitive to ambient temperature. A technically correct cold storage design creates the ideal environment to maintain the chemical structure of the milk, preventing those valuable nutrients breaking down.
• Suppressing bacterial growth: A low, stable temperature inside the cold store slows the metabolism of micro-organisms. That prevents the harmful bacteria that sour or spoil milk, guaranteeing full compliance with food safety standards.
• Maintaining flavour and sensory quality: Milk readily changes flavour or separates if it is not cooled correctly. With the support of a high-capacity refrigeration compressor pack, the temperature is always held uniform, so the milk keeps the freshness and perfect texture it had at collection.
• Extend shelf life: Where milk keeps only a few hours at room temperature, in a industrial cold storage at 2°C – 4°C its usable life extends by days, even weeks (for UHT products), giving the business far more control over distribution.
• Meeting the food industry's demanding standards: Using a dedicated cold store lets a business pass official quality inspections readily, eliminates the risk of food poisoning and builds solid consumer trust.

Common types of milk cold store by technical standard

Depending on the biochemistry of each dairy product and the scale of the operation, choosing the right cold storage milk is essential to optimising the capital cost and ensuring product quality. The dedicated store types Tân Long commonly delivers are:

• Fresh milk cold store: This system demands strict temperature stability, normally held in the range of 0°C to 4°C with an ideal humidity of 70% – 80%. That environment preserves the pure flavour and the valuable micronutrients of fresh milk right after collection.

• Yoghurt cold store: Yoghurt needs storing in the range of 2°C to 4°C. Applying a modern control cabinet system at Tân Long controls the temperature to the degree, maintaining its characteristic smooth texture and protecting the probiotics in the product.

• Milk and ice cream freezer store: For ice cream and dairy products needing long-term frozen storage, the temperature must reach the deep sub-zero range of -20°C to -25°C. Type industrial cold storage This calls for a refrigeration compressor pack with high refrigeration capacity and an envelope of Insulated panel high-density PU, to prevent ice crystals forming and protect the smooth texture of the ice cream.
• Cheese cold store: Depending on whether the cheese is fresh or processed, the temperature is set between +4°C and +12°C. Beyond temperature, Tân Long's cold storage design solution for cheese pays particular attention to the convection ventilation system, keeping the product well aired and completely preventing deterioration or mould.

Beyond the dedicated types above, Tân Long also supplies chill rooms and contact freezers in a wide range of capacities, meeting every need from a small business to a large food processing plant.

Practical applications of milk cold storage in the supply chain

System cold storage milk acts as a vital link, ensuring the continuity of the cold chain from production through to the consumer. With precise temperature control through an intelligent control cabinet system, this solution is now used widely across many business models:

• At processing and production plants: These require high-capacity industrial cold storage systems. The store is used to chill and hold raw milk rapidly after collection, to inhibit microbial growth. It is also where finished product (cartons and bottles) is held in sterile conditions before distribution.
• Supermarket chains and food shops: Where doors open and close continuously, the cold storage design here normally incorporates premium insulated cold storage door . That holds the ideal temperature range for yoghurt, butter, cheese and cream, extending shelf life without changing the product's structure.
• The F&B sector (restaurants, hotels, cafes): Installing a cold store lets these businesses hold large quantities of fresh milk, ensuring it is always properly chilled and keeps its full flavour for customers.
• Logistics centres and distribution stores: So the milk does not suffer “thermal shock” in transit, central distribution stores use high-efficiency refrigeration compressor packs to restore the temperature immediately, ensuring milk quality stays consistent even over long distances.

Standard storage temperatures for milk in a cold store

In industrial refrigeration, temperature is the “protective barrier” that prevents a product deteriorating. Every dairy product has its own biochemistry, so the storage requirements differ considerably. Setting the wrong temperature in a cold storage milk not only reduces nutritional value but causes substantial economic loss.

To help owners optimise their operation, Tân Long provides a cold storage design solution with an integrated automatic monitoring system, holding the ideal temperature range for each specific product group as follows:

Standard milk storage temperature and duration table:

Beyond temperature, air circulation inside the industrial cold storage is extremely important. We use refrigeration compressor high performance combined with industrial refrigeration with high air volume, distributing the temperature evenly to every crate of milk and eliminating the hot spots that cause localised spoilage.

Practical experience in choosing and installing a milk cold store

Investing in the system cold storage milk is a strategic question of cost and quality. For the system to run reliably, save electricity and fully protect the nutritional value of the product, owners should note the following 5 core points:

Calculating the capacity and the actual requirement accurately

Before proceeding with the cold storage design, you need to establish the volume of milk to be stored, to optimise the space and avoid wasting electricity on unnecessary empty volume.

The standard cold store capacity formula: V = m / (rho x eta) In there:

• V: the store volume required (m3).
• m: the total weight of milk to be stored (kg).
• rho: stacking density (normally 950 – 1,000 kg/m3 for milk).
• eta: the space utilisation factor (normally 0.7 – 0.85 depending on the racking system).

At small scale you can consider a mini cold store. For production plants, however, installing a industrial cold storage of tens to hundreds of cubic metres, combined with multi-tier racking, is the best solution.

Setting the right temperature range for each type of dairy product

Setting the wrong temperature is the leading cause of milk spoiling.

• Fresh milk: Held strictly between 0°C and 4°C.
• Yoghurt and pasteurised milk: Need chilled storage held steadily at 2°C to 6°C (not deep sub-zero).
• Ice cream and frozen dairy: Require a freezer store from −18°C to −25°C.

Tân Long's systems always incorporate a flexible controller, so the business owner can easily adjust the settings to suit each intake period.

Prioritising high-efficiency compressors and evaporators

The “heart” of a cold storage milk is the compressor pack. Tân Long encourages customers to use equipment from reputable brands such as Bitzer, Copeland, Danfoss or Mitsubishi.

• Refrigeration compressor: choose a model with automatic capacity control to save electricity.
• Industrial Air Cooler: needs to be durable, corrosion-resistant and to incorporate automatic defrost to keep the cold air circulating evenly through the store.

Installation technique and insulation material

Thermal performance depends 90% on the wall material and the installation process:

• Store walls: Use the panels Insulated panel High-density PU or PIR, to prevent heat loss completely.
• Door system: You must use cold storage door with tight rubber gaskets and heaters, to prevent condensation and ice forming around the door frame.
• Location: The store should be somewhere elevated, cool and airy, under cover, and convenient for vehicles loading and unloading.

Maintenance procedures and intelligent monitoring

A system cold storage milk built to a modern standard cannot do without remote alarm equipment.

• 24/7 Monitoring: Use control cabinet intelligent, alarming to your phone when the temperature moves outside range.
• Regular maintenance: Check the refrigerant level, clean the condenser and evaporators monthly and service the compressor every 6 months, to extend the system's life to 15–20 years.
