Cold Storage and Applications
Cold storage offers refrigeration for a variety of requirements and has a suite of services covering various sectors. However, the most important use of cold storage is in the food industry.
After harvest, vegetables, fruits and other perishable products are stored in cold rooms for a long time to extend their shelf life and preserve their freshness.
Cold storage, water, all kinds of medicines, laboratory samples, vaccines, devices, etc. It has applications in many different industries, such as the medical industry for storage.
Cold storage has made it possible for organ transplantation to develop and become successful.
Because chemical reactions and metals are sensitive to temperature changes, the technology is even used in the petrochemical and high-tech electronics industries.
Hotels and restaurants, the beverage industry, and forensic medical facilities use cold rooms and temperature control systems for storage.
1. Post-Harvest Storage of Products
Once fruits and vegetables are harvested, they begin to breathe and ripen.
They need to be kept at a below average temperature to slow the rate of decomposition.
Cold storage is used to preserve foodstuffs through refrigeration and controlled atmosphere chambers, where the concentration of different gases such as oxygen, carbon dioxide, nitrogen and carbon monoxide are closely maintained by sensitive devices.
The cold storage industry offers a wide range of options, from warehouse refrigeration to precision equipment and controlled atmosphere storage facilities. Since the production of fruit and vegetable products occurs on a large scale, it is not possible to market them at once.
Therefore, cold storage allows such perishable foods to be stored longer and extends their shelf life.
Moisture also plays an important role in preserving such foods. Seasonal fruits can last longer these days and are no longer only available for a certain number of months.
2. Retail Food Sector
Frozen foods (including meat, poultry, dairy) are generally easy to preserve and do not spoil easily.
Frozen foods need to be stored at a maximum temperature of -18C, and frozen food storage can only meet this requirement with special cold storage equipment.
Freezers make it possible to store, transport and distribute frozen foods over long distances.
It significantly extends the shelf life of different types of meat and is beneficial for meat distributors and processors.
In turn, it helps meat distributors expand their product range and reduce waste.
Cold storages are kept healthy with relative humidity at the highest possible level to prevent meat from burning or drying.
Various types of frozen foods have different stabilities in frozen storage, depending on how long they can remain in storage without developing abnormal flavors and whether they change color easily. Freezing preserves the sensory flavors and taste as well as the nutritional value of the product.
3. Pharmaceutical and Healthcare Industry
Cold storages have various applications in the medical field. In laboratories, blood samples must be stored at a certain temperature to preserve their properties.
Insulin, chemotherapy drugs, vaccines, eye drops and many other similar medications need to be stored in medical refrigerators. The medicine refrigerator is a standard device in hospitals, medical stores and clinics with a narrow temperature range of 2C to 8C.
Specific body samples, such as blood samples and plasma, are collected under closely monitored conditions
If it is not stored, its properties may change and become unusable.
There are increasing developments in organ transplantation and surgery in healthcare. For an organ to maintain its usefulness, it must be stored and transported at consistently cold temperatures.
Skin grafts and tissues are used in plastic and restorative surgeries and must be kept at closely controlled temperatures. Cold storages contribute to saving lives by making it possible to transport such items over long distances.
4. Chemical and Processing Industries
Industries such as oil refineries, petrochemical plants and papermaking require large cooling systems. The requirements of each industry are different; hence cooling systems are customized accordingly.
The technology includes separating gases, condensing gases, dehumidification, solvent recovery, etc. using for. Other similar industries also use refrigeration technology for cold working of metals.
6. Hospitality Industry
Hotels and restaurants have to serve a significant number of customers throughout the day.
There are many ingredients used in the dishes served that must be stored at cold temperatures beforehand.
Refrigeration is necessary to keep such ingredients fresh for use in cooking during the day.
Beverages and other consumables served in restaurants should also be kept in the refrigerator to stay fresh. Moreover, hotels need to have personal refrigeration systems to store sanitary products and keep large reserves in place for catering for larger events.
Cold storage has a number of applications that enable developments for other industries. Refrigeration and freezing allowed the food industry to transform itself.
People have easier access to food and have many options for ready meals. Medical and healthcare services are also more accessible, giving rural and remote areas access to modern benefits that were previously limited to a few people.
Cold storage reduces tons of food waste and is the most efficient way to bulk process perishable goods and has the advantage of being cost-effective for all stakeholders. The countless applications of the technology are proof of the practicality of cold storage and how it makes our daily lives more manageable.
