Design and implementation of industrial cold storage
morgue
Today, industrial cold storages have been widely used to preserve food and increase their shelf life, as well as to increase the quality of product supply. Gardeners, suppliers of dairy products and protein materials can easily optimize their exposure and increase profitability by using a cold storage manager. The types of cold storage are divided into the following categories depending on the type of food and volume and dimensions.
Types of cold storage based on working temperature
Industrial cold stores are divided into two main categories above zero and below zero. The main use of the above-zero cold storage is to store fruit, medicine, and dairy products, and the main use of the below-zero cold storage is to store meat, chicken, and fish. The third category, which is used to quickly cool food, is called the freezing tunnel. The fourth category of cold storage is used to store ice cream and cold storage. It is called two-stage.
Meat and chicken cold storage
Subzero industrial cold storage is used to store frozen food. The temperature of this type of cold storage is usually lower than zero degrees Celsius, and -18 degrees Celsius is the most common storage temperature of this type of cold storage. Usually, frozen fish, meat, chicken, and other frozen foods are stored in cold storage below zero.
ice cream freezer (two stages)
Ice cream is usually kept at a temperature lower than -18 degrees Celsius. Due to the presence of fat and cream, and in some cases due to the presence of salt in its structure, ice cream needs a low temperature so that it can maintain its shape and not take on a softened state. Two-stage compressors are used to store ice cream in large sizes.
Fruit and dairy cold storage
Cold storages known as above zero are usually used to store food at a temperature higher than the freezing temperature. The normal temperature of these cold storages is usually between 0 and 4 degrees Celsius. Fruit and vegetable cold storage and fresh dairy products such as milk, butter and yogurt, as well as fresh meat storage cold storage are of this type.
Freezing tunnel
The freezing tunnel is usually used for quick freezing of food, and its temperature is usually around -40 degrees Celsius. The high-speed freezing tunnel brings food to a temperature of -18 degrees Celsius.
Types of cold storage based on volume and dimensions
Cold storages are divided into the following categories based on volume and dimensions:
– Room cold storage
– Mobile cold storage
– Kanksi cold store
– Large industrial cold storage
Construction of a small cold storage
The use of a cold room is usually for the construction of a small and medium cold room and it is used to store food in restaurants, distribution centers, hotels or to store fruit in gardens. In this way, a room inside the building is first insulated with the help of sandwich panels and then Cooling equipment is installed inside it.
Large industrial cold storage
Large industrial cold storages, which are usually used to store and store food in bulk, usually consist of many rooms, each room receives cold according to the need, and food can be stored individually in each room. Perishable food storages. The public areas of the city where large gardeners or the main distributors of meat and poultry store their products are usually in this category. These warehouses use freon or ammonia system depending on the conditions.
Connexion morgue – mobile morgue
If there is a need for a small and medium-sized cold storage, but the desired space for its installation is in a shed or in an open space, a portable cold storage or a connexion cold storage is used, which instead of using the walls of the room, is from a container or structure. Metal is used.
Types of cold storage based on the type of atmosphere
Atmosphere controlled cold storage
Atmospheric control cold storage is built for long-term storage of some materials, which requires the creation of special conditions in terms of the composition of the air inside the room. Among these conditions is the reduction of oxygen or ethylene concentration. In this case, the room is completely airtight and the air composition of the cold room is controlled in two ways.
– In the first type, carbon dioxide is injected from the tank adjacent to the room and changes the composition of the air.
– In the second case, some air compounds are separated from the air with the help of special filters and leave the room.
With the help of this process, the spoilage of some food items is delayed and the conditions for their long-term storage are provided.
Normal cold storage
In a cold room with normal air, only the temperature and humidity of the air are controlled. The construction of food cold storage is mainly done in this way.
