What is the advantage of light milk sterilizer

Milk - a great product that is one of the staple foods, can be dangerous. Milk itself is a favorable environment for bacteria and microbes, and if it was obtained from a sick animal, it can cause many dangerous diseases: tuberculosis, brucellosis, staphylococcal and streptococcal infections, etc. Before getting to the table in the form of various dairy products , it must undergo special treatment - sterilization. The procedure can be a special tool - light sterilizer for milk (CCM).

Types of milk sterilization

Existing technologies of milk disinfection, which are used today in the dairy industry and at home, are based on heat treatment:

1. Pasteurization runs for 30 minutes at 65 ° C. The shelf life of such a product is 2 weeks.
2. Process sterilization lasts for 30 minutes at a temperature of 130-150 ° C. In such conditions, all microorganisms are killed, including lactic acid. The shelf life of products that have undergone such processing lasts up to 1 year.
3. At ultrapasteurization milk is exposed to very short-term exposure, literally, within 4 seconds. But the temperature here reaches 135 ° C. Then the product is gradually cooled to low temperatures, approximately to 4-5 ° C. Such milk retains a maximum of useful properties, and its shelf life reaches 2 months.

Light sterilizer performs decontamination without the use of high temperatures, and with the help of ultraviolet radiation, destructive to pathogenic bacteria and microorganisms.

The principle of operation of the SMS

The basis of the SMS is gas discharge lampproducing a powerful flux of ultraviolet radiation. Devices based on UV rays have long been used to disinfect rooms, ponds, and individual objects. Scientists have discovered that ultraviolet light with a wavelength of about 254 nm has a destructive effect on the DNA of microorganisms, depriving them of the ability to reproduce.

How to apply

The light sterilizer is intended for processing milk in industrial conditions and is necessary in every livestock farm. What you need to know about it for a successful application?

1. SSM operates from the mains with a voltage of 220 V.
2. The device is ready to work in 4 minutes after connecting to the network. There is a way to check readiness for work. If the red object, brought to it at a distance of one meter, becomes brown, it means that the device can be started to use.
3. The device is placed in a container with milk at a distance of 50 cm from the surface.
4. The sterilization process should take place with continuous mixing of milk. UV radiation cannot penetrate into the deep layers of milk due to its opacity.
5. Every 10 minutes of exposure, samples are taken for the presence of pathogenic microflora.
6. The process is considered complete when the samples will be negative.

The method of sterilization of milk at home

At home, we most often use the usual and affordable method of sterilization - boiling. Of course, this method does not preserve all the beneficial properties of milk.

Modern devices, invented to help mothers, allow for more gentle sterilization for milk. For example, a sterilizer operating on the basis of hot steam. Moreover, it can be used as a sterilizer for the breast pump, bottles and small toys for infants.

Conclusion

Milk, subjected to heat treatment, of course, inferior in beneficial properties to the product treated in a cold way. Light sterilizer due to its high cost is most often used only in industrial environments, but it can be used at home.
