Temperature characteristics of frozen storage and cold storage:
Cold storage/cool storage: The temperature usually ranges from -22°C to 22°C, suitable for long-term preservation of goods.
With outstanding features, frozen storage and cold storage are indispensable solutions in the modern cold supply chain, helping businesses optimize preservation quality and prolong product shelf life.
Structure of industrial cold storage
Industrial cold storage is an indispensable preservation solution in the food, seafood and pharmaceutical industries. Let's explore the structure of industrial cold storage, including the following main parts:
1. Cold storage shell
The shell is designed from specialized materials such as EPS Panel and PU Panel, each type is suitable for different usage needs:
EPS Panel (Polystyrene):
- Density: 18–22 kg/m³, with white foam core.
- Two sides: PVC coated (0.41mm–0.8mm) or color-coated galvanized steel.
- Connection: Nail-lock or mortise and tenon.
- Usually used for cold storage.
PU Panel (Polyurethane):
- Density: 38–42 kg/m³, yellow foam core.
- Two sides: PVC coated or color-coated galvanized steel.
- Connection: Camlock or mortise and tenon.
- Suitable for cold storage thanks to its good heat resistance.
Advantages of the shell:
- Excellent insulation, prevents cold air from escaping.
- Soundproof, heat/cold resistant.
- Easy to clean, high aesthetics.
- Flexible installation, saving construction time.
Assembly method: Yin-yang mortise and tenon or camlock (camlock preferred because it is quick and convenient).
Standard size:
- Width: Multiple of 300mm.
- Length: 1800mm, 2400mm, 3000mm, 3600mm, 4500mm, 4800mm, 6000mm.
2. Cold storage doors
Storage doors often use German standard products (Gatter) with two main types:
Opening doors: Common sizes from 600×1600mm to 900×1900mm.
Sliding doors: Sizes from 1000×2000mm to 2500×3500mm.
Storage door structure:
- Sealed cold joints, helping to maintain temperature.
- Two sides covered with stainless steel or colorbond corrugated iron, PU Foam layer 75–125mm thick.
- Heating resistor keeps the door dry and clean.
- PVC frame recessed into the panel wall.
Advantages:
- Stainless steel 304 material, rust-free, durable, shiny.
- Airtight structure, safe with anti-locking latch inside.
- Easy to replace and maintain.
3. Compressor cluster system
Classification by origin:
- Cluster built in Vietnam: Meets basic standards or built according to requirements.
- Asian imported cluster: Includes brands such as Bitzer, Tecumseh, Danfoss, SunJin...
- European imported cluster: Leading brands such as Bock (France), Bitzer (Germany).
Compressor cluster structure:
- Air cooling: Closed or open type, suitable for high temperature conditions. Heat accumulation technology helps save electricity.
- Water cooling: There are types using fresh water or salt water.
- Condenser compressor cluster: Designed according to requirements, ensuring high efficiency and suitable for preservation needs.
With advanced structure and optimized components, industrial cold storage brings high preservation efficiency, helping businesses maintain product quality and optimize operating costs.
The important role of using cold storage
Cold storage plays an essential role in preserving product quality, especially in the cold supply chain. This is an indispensable solution for many industries, from food, seafood to pharmaceuticals.
Preserving the quality of goods
- Cold storage uses a sudden freezing method, "condensing" the activity of matter and inhibiting the growth of bacteria and viruses.
- Special items such as: frozen food, seafood, agricultural products, meat, fish ... all maintain the best value and quality in this environment.
- After freezing, the goods are stored in packages and transported to other cold storages for further preservation.
Importance of industrial cold storage systems
Effective food preservation
- Cold storage systems help preserve fresh food and prevent spoilage.
- This is the optimal solution for perishable items such as meat, fish and other frozen products.
Ensure a stable supply chain
- Cold storage supports effective supply chain management by controlling supply and maintaining stable goods in the market.
- Helps businesses flexibly meet customer needs.
Save costs and reduce waste
- Properly stored goods will minimize loss and eliminate poor quality products.
- Helps businesses optimize profits by maintaining the quality of goods and reducing replacement costs.
Choosing the right cold storage system
To ensure operational efficiency, businesses need to pay attention to the following factors when choosing a cold storage system:
- Size: Choose a size suitable for the space and storage needs of goods.
- Material: Prioritize durable materials such as brick, concrete, or stainless steel.
- Performance: Evaluate the ability to maintain stable temperatures and save energy.
Using cold storage not only ensures the quality of goods but also contributes to optimizing costs and improving efficiency in the supply chain. This is a decisive factor for the success of businesses in industries related to the preservation and transportation of goods.
Applications of cold storage in life
Cold storage is now widely used in many fields such as industry, agriculture, food and medicine. This equipment brings outstanding benefits in preserving, maintaining product quality and optimizing the supply chain.
Preserving agricultural products
- Cold storage helps preserve agricultural products such as fruits and vegetables, maintaining ideal humidity and temperature to prolong their shelf life.
- In particular, cold storage is often used during transportation to keep agricultural products fresh and avoid damage due to changes in environmental temperature.
Preserving seafood
- Seafood such as fish, shrimp, and crab are very susceptible to spoilage if not properly preserved. Cold storage helps "freeze" biochemical activities, preventing bacteria from growing and preserving nutritional value.
- This is considered an optimal preservation solution, helping seafood stay fresh and ensure quality when reaching consumers.
Application in the beer industry
- Cold storage plays an important role in the production and preservation of beer, helping to maintain the original concentration, flavor and color.
- Thanks to a stable temperature-controlled environment, beer always maintains the highest quality before being distributed to the market.
Preserving chemicals and equipment in clean rooms
Cold storage is used to store chemicals and sensitive equipment for research and production in clean rooms.
Strictly controlled temperatures help protect the safety and ensure the quality of these materials.
Cold storage is not only a preservation tool but also a key factor in many industries, helping to reduce losses, improve product quality and optimize operational efficiency. Proper application of cold storage is the key to ensuring sustainable value for products in life.
