If you want to know about different types of Cold Storage, you are here at the right place as we will take you through the complete guide on cold storage and its different types.
How frozen products should be arranged, handled, and stored is of vital importance for a good service within the hotels or cafeterias. Complying with these good storage practices determines the final quality and shelf life of any product.
Food products that are frozen include a wide variety. From those that are kept in their fresh states such as fruits, vegetables, juices, meats, seafood, poultry, and fish, or even prepared foods such as bread, ice creams, precooked, among others.
Therefore, the product storage process will depend on the composition and nature of the food. As well as, the care during its selection, handling, and preparation when freezing.
Before we proceed to the types of cold storage plant, let us know better what is cold storage?
What is cold storage?
Cold storage is a process in which temperatures higher than freezing are used, so we can speak of conditions between 15º to 2º C. For food to freeze, it has to be subjected to temperatures of -2º C or lower.
Now let us learn about types of the cold storage warehouse.
Types of cold storage:
There are different types of cold storage warehouse:
– Frozen storage: refers to the process of collecting food that has been frozen to maintain its nutritional and organoleptic properties. The required temperatures are 18º C below zero, or even lower. Its main objective is to preserve food for long periods. Freezing is mostly applied to meat and fish products.
– Refrigerated storage: Refrigerated storage is also one of the types of cold storage plant. Unlike frozen storage, this is a process for the preservation of perishable foods, those that must be preserved cold to delay microbial activity. Refrigeration is most used in fruits, vegetables, juices, bakery products, etc. Refrigeration chambers are used for their storage, in which only products of the same nature must be collected.
The required temperatures range between 0º and 5ºC.
Temperature as a key factor during storage:
For types of cold storage plant to be successful, a key factor must be considered, which is fundamental to ensure that refrigerated or frozen foods maintain their nutritional qualities.
One of the factors to consider while choosing types of cold storage warehouse is the temperature. The effect of temperature is different for each food, but it can be averaged that for every 10º C that is reduced, the process of reproduction of microorganisms is delayed 2 to 3 times. Using a cold and controlled temperature, these reactions are delayed so that the products can last twice as long, and therefore their commercial value increases.
Some foods have a temperature coefficient that increases widely when they experience conditions close to freezing. For example; fish subjected to a temperature of 0º C or less, are preserved for much longer than if they were subjected to temperatures of 1º C.
It is important to note that cold does not eliminate microorganisms, but rather delays their multiplication, so when the cold storage process is interrupted, bacterial activity resumes.
Recommendations during storage logistics
– Avoid excess humidity, as it favors the growth of germs.
– Do not store food directly on the floor.
– Transport frozen food in insulated bags or containers that keep it cold.
– Store raw food separately from cooked food.
– Keep perishable foods refrigerated.
– The cold chain must be maintained throughout the process through which the food passes. If the correct temperature is not maintained throughout the process, the food will suffer irreversible consequences.
For the preservation of frozen food, types Of Cold Storage are the best-known method of all. This is why many companies turn to food freezing and refrigeration. Above all, because they can retain their qualities without major changes, as long as the cold storage is carried out in the indicated way.
Frozen products represent a new and safe option in the food industry. In the same way, they represent a great ally for the business, redefining the eating habits of large communities.
If types of cold storage warehouse and its operations are more demanding every day, it is even more so in the field of frozen and refrigerated products. Mainly, because in some products such as food it is easy to detect that the cold chain has been interrupted and avoid its consumption, but in others, this is not possible. This is the case of vaccines and medical references whose consequences of use in poor condition are incalculable. For this reason, in cold logistics processes, it is a requirement to take care of and control every detail.
The market for products that require maintenance at controlled temperatures has experienced great growth in recent decades. It is due to the requirements of the merchandise and the needs of the end consumer, who demands a high level of service and conditions for an intact treatment from the end of the manufacture until it receives the load.
Products must be in perfect condition to avoid problems that arise after incorrect treatment in the logistics process. Sometimes an interruption in the cold chain is recognizable: the crystallization of the merchandise, an unattractive appearance, deterioration, or the poor condition of the merchandise is visible. However, in other cases, the loss of shelf life is not identifiable, as occurs in medical articles, vaccines, and various components. The consequences produced by breaking the cold circuit are then difficult to quantify.
The Different types of cold storage warehouse cold chain is the set of fixed, mobile, and operational elements that guarantee the channeling of any type of product that requires an adequate temperature for its maintenance, from the harvesting phase (most references are perishable: meat, vegetables, fruit, etc.) or production to the point of sale. Such temperature must be stable and regular: below –-18ºC for frozen products and positive for fresh ones.
We are sure, now you have complete knowledge about different types of Cold Storage.
