Freezing is an effective method for long-term preservation of fruit and vegetables, retaining their quality over long periods. It is also regarded as superior to other conventional methods of preservation, such as canning and dehydration, with respect to safety and nutritive qualities (Fennema, 1977).
Cold storage involves the use of specialized equipment to maintain goods at their proper temperature. The technology is essential to keeping goods fresh and safe.
Logistics
Frozen storage is important in many industries, including food, pharmaceutical and candle-making. These facilities need to be designed properly to maximize the amount of space and promote efficient product management.
Temperature-sensitive products are often transported over long distances, so it is essential that they are cooled and stored appropriately to ensure they don’t spoil in transit. This is why specialized equipment like reefers, kho lanh thuc phamvaccine freezers and refrigerators, insulated pallets and containers are used throughout the cold chain logistics process.
It’s also important to ensure the employees in these warehouses are provided with appropriate personal protective equipment (PPE). This helps minimize health risks and operational efficiency.
Automated systems are a vital part of frozen storage warehouses and allow the operators to deposit or extract goods automatically. These facilities are often installed with AS/RS (automated storage and retrieval systems) that consist of single-deep or double-deep pallet racking, a stacker crane and other components to improve productivity.
Refrigerant
Refrigerant is a liquid that runs through your air conditioning system and refrigeration system, collecting and transferring heat energy as it goes. Throughout the entire refrigeration cycle, refrigerants change from liquid to gas and back again, which lets them absorb and transfer heat away from your cold storage space.
Refridgerants are usually grouped into two categories: hydrofluorocarbon (HFC) and chlorofluorocarbon (CFC). CFC refrigerants were used extensively in the past but have been phased out due to their ozone depletion potential (ODP).
A typical refrigeration system will contain several lines or tubing that connect each of the major components, including the evaporator, compressor, and condenser. These lines are designed so that the refrigerant will not escape into the atmosphere.
Refrigerants are stored in cylinders, cans, and tanks of various types and sizes. Refrigerants are commonly used in the refrigeration and air conditioning industry, so it is important to know how to store them properly.
Cold Storage Warehouse
Cold storage warehouses are places where goods can be stored at a controlled temperature. They can be used to store ice cream, vegetables and other products that need to be kept at a particular temperature for long periods of time.
There are several different types of cold storage warehouses, from individual units to whole dedicated facilities. Choosing which one to use will depend on the capacity of its storage systems and how well they facilitate goods management.
In addition, the location of a facility can also affect its performance. A cold storage warehouse requires a heavy load, so the foundation of the building may need to be reinforced.
In addition, workers who work in these facilities must be properly protected. They should wear insulated pants, coats and gloves. These items can help them stay comfortable and keep their productivity high.
Temperature Control
Temperature control is a crucial factor in frozen storage. Keeping goods at the appropriate temperature ensures that they remain fresh and safe to consume or use.
Frozen products should be stored at -18degC (or lower) to preserve their quality and keep them from discolouring or losing vitamins. If the temperature rises, this can lead to damage and spoilage.
Having a system in place to monitor temperature is essential for maintaining good food safety and demonstrating due diligence for regulatory agencies. It can also prevent equipment failure and inventory loss before they happen.
A cold storage warehouse can be made more efficient and effective by incorporating temperature monitoring systems that record and transmit data in real time. These solutions eliminate the need for pen and paper logs. They also provide a detailed audit trail that proves compliance and reporting for food safety regulations.
