Calculating the size and capacity of a 100-ton cold storage
Calculating the size and capacity of cold storage is an important step to ensure efficient storage and cost savings.
Formula for calculating standard capacity
The formula for calculating standard cold storage capacity is:
V = E / gv
In there:
- V: Cold storage capacity (m3)
- E: Total weight of goods to be stored (kg)
- gv: Loading rate (kg/m3), depends on the type of goods, arrangement method and shelf system.
For example:
- If you need to store 100 tons of frozen meat (E = 100,000 kg) with a loading capacity of 400 kg/m3 (gv = 400), then the required cold storage capacity is: V = 100,000 / 400 = 250 m3.
- If you need to store 100 tons of fresh vegetables (E = 100,000 kg) with a loading capacity of 200 kg/m3 (gv = 200), then the required cold storage capacity is: V = 100,000 / 200 = 500 m3.
Factors that influence load capacity include: type of goods (frozen meat can be packed more tightly than fresh fruits and vegetables), method of arrangement (using shelves and pallets increases load density), and shelving system (the right type of shelving helps maximize space utilization).
Standard size and optimal space
The standard size for a 100-ton cold storage is usually around 8m × 5m × 2.5m (length x width x height). However, this size can vary depending on the type of goods, shelving system, and operational requirements.
The optimal height of the cold storage should be sufficient to install the racking system and ensure good cold air circulation. The distance between the blocks of goods should also be calculated to ensure ventilation and easy movement.
The ratio of working space (aisles, loading and unloading areas) and storage space needs to be balanced to ensure operational efficiency and labor safety.
Loading density and efficient arrangement methods
The optimal loading density depends on the type of product. For example, frozen meat can be loaded at a higher density than fresh vegetables.
Common methods of cargo arrangement include:
- FIFO (First In, First Out): First in first out, suitable for products with short shelf life.
- LIFO (Last In, First Out): Last in, first out, suitable for products with no shelf life or long shelf life.
Specialized racking and pallet systems help optimize space and increase cargo density. The arrangement of goods must ensure that cold air circulates evenly throughout the warehouse, avoiding goods from freezing or not being cold enough.
Specialized construction and materials
The structure and materials of cold storage directly affect the preservation efficiency and life of the warehouse.
Insulation panels and technical specifications
Insulation panels are an important component of cold storage, helping to prevent heat exchange between the inside and outside of the warehouse.
Below is a table of specifications for some popular types of insulation panels:
| Panel type | Core material | Thickness (mm) | Thermal conductivity (W/mK) | Advantage | Disadvantages |
|---|---|---|---|---|---|
| EPS | Polystyrene | 50-200 | 0.035-0.040 | Low cost, easy to construct. | Poor fire resistance, low durability. |
| PU | Polyurethane | 50-200 | 0.022-0.025 | Good insulation, high durability, better fire resistance than EPS. | Price is higher than EPS. |
| PIR | Polyisocyanurate | 50-200 | 0.020-0.022 | Best insulation, high durability, very good fire resistance. | Highest price. |
The insulation and durability standards of the panels need to be suitable for the operating temperature and environmental conditions. The cost and payback period of each type of panel need to be carefully considered.
Specialized cold storage door system
Cold storage doors are a weak point in terms of insulation, so it is necessary to use specialized doors to minimize heat loss.
Technical specifications of cold storage doors include:
- Hinge: Strong, durable, and adjustable tightness.
- Sliding door: Space saving, suitable for warehouses with limited area.
Comparison of efficiency between hinged doors and sliding doors: hinged doors are more closed but take up more space, while sliding doors save space but are not as closed.
Security locking and alarm systems help prevent theft and ensure the safety of goods. Anti-frost and heat loss solutions help save energy and maintain stable temperatures.
