Types of mortuary
This cooling system is divided according to the volume and type of food.
Division based on temperature One of the divisions that are done in relation to cold stores; Based on the temperature, they are classified into four categories: below zero, above zero, freezing tunnel and two-stage cold storage.
This system is useful for storing materials such as fish, chicken and meat at a temperature below zero and about -18 degrees Celsius, and for dairy products, medicine and all kinds of fruits, above zero temperature, which is the desired temperature for storing all kinds of fruits and vegetables from 0 It is up to 4 degrees Celsius. The freezing tunnel is also used for cases that require quick freezing in a short time, and the two-stage system is special for storing ice cream.
Division based on dimensions and volume
Cold storages are divided according to dimensions and volume as follows:
1- Large industrial cold storage
This model is used to store and store food with a very high volume. Its structure consists of many rooms. that each food item can be stored separately in these rooms.
And each of these rooms receives the desired cold according to the desired food item. This warehouse model uses an ammonia or freon system to store food, depending on the conditions.
2- Mobile cold storage
The size of this type of cold storage is medium and small, but it is very practical and suitable for installation and use in sheds and open spaces. In this type of cold storage, metal structures or containers are used instead of room walls.
3- Room cold storage
This model of cold storage is usually used in hotels, restaurants, distribution centers and fruit shopping centers in the garden. The way it is made is that first a small room inside the building is completely insulated with sandwich panels and after the insulation is done, all the cooling equipment is installed in it.
Atmosphere control cold storage
This model of cold storage is very suitable for storing and storing food for a long time, which should reduce the concentration of ethylene and oxygen in the air. In this model, air composition control is done in two ways:
- Injection of carbon dioxide from the adjacent tank into the chamber
- Removing the desired compounds from the air by special filters and removing them from the chamber
