Refrigeration warehouses: features of storage
Refrigeration warehouses play a key role in modern logistics, ensuring the safety of perishable goods such as food, medicines, flowers and other temperature-sensitive products. Competent organization of storage in such warehouses allows you to minimize losses and guarantee the quality of products throughout the entire period of storage and transportation.
What is a refrigeration warehouse?
Refrigeration warehouse This is a specially equipped room in which low temperatures are maintained (from -40 °C to +10 °C) to preserve the quality of goods. Such warehouses can be used to store frozen and chilled products.
Types of cold storage:
- Refrigerated warehouses (+2...+10°C) - for storage of fresh vegetables, fruits, dairy products, meat, fish, medicines.
- Freezing warehouses (-18...-25 ° C) - designed for storage of frozen fish, meat, semi-finished products, ice cream.
- Deep-freezing warehouses (-30...-40°C) – used for long-term storage of products with a high degree of freezing, for example, meat or fish before long-term transportation.
- Combined warehouses - equipped with different temperature zones for storage of different categories of products.
Basic Requirements for Refrigeration Depots
- Temperature conditions
Maintaining a set temperature is the main factor affecting the quality of storage. Temperature fluctuations can lead to spoilage of products. For this purpose, automatic temperature and humidity control systems are used.
- Humidity
Optimal humidity depends on the type of stored goods:
- For fruits and vegetables – 85-95%
- For meat - 75-85%
- For frozen foods – 90-95%
- Ventilation
Fresh air prevents condensation and fungal formations that can spoil the products.
- Hygiene standards
Sanitary regulations require regular disinfection of warehouses, especially when it comes to food. Equipment and walls must be made of materials resistant to moisture and low temperatures.
Features of storage of different categories of goods
Food products
- Meat and poultry: Stored at a temperature of -18...-25 ° C. It is important to avoid re-freezing.
- Fish and seafood: The optimal storage temperature is from -20°C to -30°C.
- Dairy products: Stored at a temperature from 0 to +4 ° C.
- Fruits and vegetables: Most require a temperature of +2...+8°C, but bananas, for example, are stored at +13°C.
Medications
Pharmaceuticals require special storage conditions, as temperature variations can make them ineffective. Some vaccines, for example, should be stored at -20°C and insulin at +2...+8°C.
Flowers and plants
Require temperatures of about +4 ... +7 ° C and high humidity, so as not to fade.
Modern technologies in refrigeration warehouses
Modern warehouses are equipped with:
- Automatic temperature and humidity control systems
- Warehouse robots and automated shelving
- Energy saving technologies (for example, thermal insulation panels)
- GPS temperature control during transportation
Refrigeration warehouses An integral part of the supply chain of perishable goods. Competent compliance with temperature, humidity and sanitary standards allows you to keep products in proper condition, reduce losses and extend the shelf life. Technology advances make this process more efficient, reducing costs and improving storage quality.
