Matters Needing Attention In The Use Of Freezers Inside The Supermarket

- Jan 03, 2018 -

Now the pace of life is very fast, although the freezer is used to the electrical appliance store food, but do not put the food in the cabinet is health, especially inside the supermarket if used for a long time and regular cleaning cabinet, will breed a lot of bacteria so from the cabinet, and the contamination of food. The food in this way, although it looks fresh, is actually deteriorating.

The common cold storage temperature of the food is 4 to 8 degrees centigrade, and in this environment, most of the bacteria will slow down. However, some bacteria are cold, such as Jerson, Listeria and so on. At this temperature, they can grow rapidly. If eating foods infected with these bacteria, they will cause intestinal diseases. The cupboard in the freezer, the temperature at minus 18 degrees Celsius, the temperature, the general bacteria can be inhibited or killed, so the food preservative effect inside the store has better. But freezing does not mean that it can be completely germicidal, and some of the more antifreeze - resistant bacteria can survive. So, from another point of view, if you don't do it regularly, it will become a "hotbed" of some bacteria.

The storage time of any food in the freezer of supermarket is not too long, so it is best to buy it with buying, because the storage time is too long, which not only affects the delicious food, but also produces peculiar smell. There are also some fruits, such as bananas, apples, and so on, if they have long been placed easily metamorphic, once the deterioration will send out a kind of harmful gas to the human body. Do not store too much food in the cabinet, which will make the external temperature of the food low and the internal temperature high to lead to deterioration.

The refrigeration of a machine depends on the rotation of the compressor. Because of the principle of electromagnetic induction, the rotation of the motor will generate certain electromagnetic, so that there will be some static voltage on the shell. Any kind of household appliances sensors (including household appliances TV, air conditioning etc.) as long as it is not grounded in the moment shell start and stop will have the electrostatic voltage (the screen will have some static, also at the moment to switch with our hands touching the screen when there will be the sound of parapara). Because the electrostatic voltage itself is very small, it does not cause any harm to the human body. In spite of this, the ice cabinet, as a kind of electrical appliance, must have reliable grounding, otherwise if its own insulation performance fails, there is a danger of electric shock. Therefore, it is necessary and necessary to install grounding wire.
