Features and equipment of Kharma cold storage

Refrigerators act as one of the most important equipments to supply the cold chain of preserving dates. These places provide ideal conditions to maintain the quality of dates by creating controlled temperature and humidity. Cold stores can protect dates from environmental factors such as heat, humidity, pest and pollution. Also, the use of cold storage can help reduce storage costs and increase the useful life of dates. In many countries, the use of cold storage is recognized as a standard for date storage and allows producers to store their products in optimal conditions and market them at the right time.

Temperature and humidity are two key factors in maintaining the quality of dates. High temperatures can cause dates to dry out and lose their flavor and aroma, while low temperatures may cause dates to freeze and change their texture. On the other hand, high humidity can cause the growth of fungi and bacteria, which also affects the quality of dates.

Persistence of dates is significantly different in different conditions. Under normal conditions and without the use of cold storage, dates may last only a few weeks. But if stored in a cold room with proper temperature and humidity, this shelf life can be extended to several months. For example, dried dates stored in a refrigerator can last up to a year without deterioration, whereas if stored at room temperature, they may last only a few weeks. This comparison clearly shows how storage conditions can affect the quality and shelf life of dates and increases the importance of using cold storage in this context.

Cooling systems in date cold stores play a vital role in maintaining the quality and freshness of dates. These systems usually include compressors, condensers and evaporators. Compressors reduce the temperature by compressing the refrigerant gas, and this causes cooling in the interior of the cold room. Along with these systems, proper ventilation is also necessary to distribute cold air evenly among the date packages and prevent heat accumulation. The use of strong fans and ventilation systems suited to the needs of the cold store helps to maintain the desired temperature and humidity.

Proper insulation is one of the key components in the design of cold storage rooms. Using high-quality insulating materials, such as polyurethane or polystyrene sandwich panels, helps to prevent energy loss and reduce operating costs. Proper insulation also insulates and prevents temperature exchange in the cold room and helps maintain a constant temperature. In addition to insulation, temperature control systems are also very important. These systems usually include thermostats and temperature sensors that automatically monitor and adjust the temperature. By creating a constant and controllable temperature, it is possible to prevent the destruction and corruption of dates.

Humidity is one of the important factors in keeping dates. Humidity control systems should be designed to maintain relative humidity in the range of 55-75%. It is necessary to use hygrometers and dehumidifiers in this direction. By removing excess moisture from the environment, these devices prevent the creation of favorable conditions for the growth of fungi and bacteria. Also, moisture management not only helps to maintain the quality of dates, but also prevents problems such as mold and corruption. Using new technologies such as smart sensors can help improve humidity control and increase the efficiency of cold storage.

Compressors and condensers are vital components in date cold storage systems. Compressors are responsible for compressing refrigerant gas and are divided into two main types, piston and scroll. Piston compressors are used in large volumes due to their high power, while scroll compressors are a good choice for smaller cold stores due to their efficiency and lower noise. On the other hand, condensers are responsible for transferring heat from the refrigerant to the outside environment. These equipments are divided into two categories, air and water. Air condensers are usually used in smaller cold stores and are easier to install, while water condensers are used in larger, industrial cold stores and achieve greater efficiency.

Monitoring and control systems are very important to manage and monitor the temperature and humidity in the date cold storage. These systems include temperature and humidity sensors, digital displays and warning systems. Temperature sensors continuously measure the temperature and send warnings to the operator in case of unauthorized changes. In addition, temperature control systems allow you to adjust the temperature automatically. These systems can also be monitored online and controlled remotely, which increases efficiency and reduces costs. In general, the existence of monitoring and control systems ensures the quality and preserves the freshness of dates over time.

The tools for keeping and transporting dates are also very important. To store dates in the cold room, you should use suitable shelves and baskets that help the flow of cold air and prevent damage to the product. Plastic baskets with good ventilation are considered as an excellent option for this work. In the transportation sector, it is necessary to use refrigerated trucks or vans for transporting food. These cars should be designed in such a way that the temperature and humidity inside them are maintained within the standard range of keeping dates. Also, using proper loading equipment such as forklifts and conveyors can help improve the efficiency of the transportation process and reduce loading and unloading time.
