Purchase of dairy cold storage
Dairy products are mainly produced in two ways. The traditional method and the pasteurized method, each of which has its own characteristics. Milk is the main base of all dairy products. Both processes are for cleaning the product from germs. Their difference is in the way the two processes work. Therefore, the production of each dairy product is different from the other. The production of some cold storage products and also their storage depends on the cold storage space. Because the process of keeping dairy products cold and maintaining the quality and increasing the shelf life of the products is very important. Therefore, the need for a cold storage is essential.
Types of cold storage for dairy products
Dairy products are marketed in various forms based on their characteristics and type of consumption. As an example of frozen products such as butter and milk, cream that enters the market, it is noted that frozen products are kept in a space with a temperature below zero, which does not prevent the ice crystals from melting and reducing the quality of the product.
Dairy products are divided into two general categories based on the type of product and the time required for storage.
Dairy cold room with sub-zero temperature
Dairy cold storage with above zero temperature
Cold storage for dairy products below zero
The temperature range of this cold store is between -18 and -30 degrees Celsius. The type of product and storage time are the factors that determine the temperature range of the cold store. Dairy products do not need high humidity to be stored in sub-zero cold stores, and most of these cold stores are used to store frozen materials such as frozen yogurt, frozen cheese, and frozen cream, which we have briefly shown in the table below.
Product Name | Celsius temperature | Storage period |
Frozen pasteurized milk | _20 | 4 months |
Frozen condensed pasteurized milk | _20 | 10 months |
Frozen pasteurized cream | 18 to 30 | 26 to 38 weeks |
frozen cheese | _20 | 6 months |
animal butter | 15 to 20 | 6 months |
frozen yogurt | _20 | 3 months |
Dairy cold storage above zero
The temperature range of this cold store is between 0 and 10 degrees Celsius. Dairy products are consumed in large quantities. It is very suitable for storage in these cold stores. The type of product and the duration of storage are two important indicators to determine the temperature range of the cold store. You can see a table below to briefly store products.
Product Name | Celsius temperature | Storage period |
pasteurized milk | +5 | According to the expiration date |
cream | +5 | 7 days |
Margarine | 0 to 4+ | 4 to 8 weeks |
pasteurized butter | 0 to 4+ | 2 to 3 weeks |
yogurt | 0 to +5 | 3 weeks |
Cheese | +5 | 3 weeks |
The cold storage of dairy products in special conditions is as follows.
What is the cold storage of raw milk like?
Milk is the main base of all dairy products. Because this product is sensitive and it spoils quickly if the temperature fluctuates. Its preservation is very important. The process of milk preservation is that after milking, the raw milk from the dairy farm is kept cold for 2 to 3 hours in the freezing chamber to a temperature of 4 degrees Celsius, and in this time interval between the factory And animal husbandry must remain at the same temperature, and if it is not processed after entering the milk factory, it must remain cold in the same temperature range. Raw milk produced within 24 hours must be pasteurized immediately and kept cold at a temperature of less than 4 degrees Celsius. had
What is the cold storage of pasteurized milk like?
The way to store raw milk is completely different from pasteurized milk. Raw milk is placed in the vicinity of cold water to reduce the temperature and prevent this product from spoiling. In this case, the possibility of growth of germs and proliferation of bacteria will be zero. It should be pasteurized for 24 hours. Raw milk must be pasteurized for freezing, then homogenized and finally frozen. This product can be kept at -20 degrees Celsius for 4 months.
Pasteurized milk is placed in the vicinity of cold water and finally ice, and it is brought to the desired temperature, preferably 5 degrees Celsius. In this way, the milk is cooled. Then they are packed and stored at the same temperature and stored in the dairy refrigerator until the date of use.
Cream cold storage: Fresh cream with 50% milk fat is pasteurized at 90 degrees Celsius. Then they are cooled and made into ice molds. The frozen pasteurized cream is placed in a mold in plastic bags and they are finally put in cardboard packages. The frozen creams can be kept at a temperature of -18 to -30 degrees Celsius. and kept for 26 to 38 weeks.
Cheese refrigerator: After cheese production, freezing operation is required to store cheese. Hard and nutritious cheeses like cheddar are stored at -20 degrees Celsius after freezing and can be stored for 6 months. The recommended temperature for storing cheeses that have a lot of water is between 5 degrees Celsius.
Cold storage of butter: the temperature range for storing butter is between -15 and -20 degrees Celsius. In the process of extracting butter from raw, the relevant cylinder must be kept cold and the packaged butter can be kept at a temperature between 0 and 4 degrees Celsius for 3 to 4 It can be kept for a week, and if we want to keep it for a long time, it should be between -15 and -20 degrees, in which case it can be kept for a year.
Yoghurt refrigerator: Yoghurt can be refrigerated and frozen in a combination with fruit and dry ingredients. The temperature required for this operation is -20 degrees Celsius, and the storage time is about 3 months. Keeping yogurt cold reduces the acid effect and Sustainability is ours.
