Things you don't know about commercial refrigerators in supermarkets

First，Precautions for commercial display freezer.

With the continuous development of society and the improvement of the quality of life, the market and scale of commercial refrigerators continue to expand, ranging from hotels and supermarkets to cold drinks shops, fast food chains, and so on. Commercial refrigerators are so versatile, so what should be paid special attention to during use?

(1) Use independent dedicated sockets and perform reliable grounding.

The power supply of the freezer is equipped with a (grounded) plug that conforms to a standard three-wire (grounded) socket. Under any circumstances, do not cut or remove the third pin (ground) of the power cord.

(2) It is forbidden to put flammable and explosive dangerous goods and strong corrosive acids and alkalis in the freezer.

(2) Do not use flammable sprays near the refrigerator to avoid fire.

(5) When there is leakage of flammable gas such as gas: close the gas leakage valve, open the exhaust device, doors and windows, and do not unplug or plug in the power plug of the refrigerator.

(6) Keep the keys properly, and don't let children play in the freezer to avoid accidents.

(7) Once the freezer is cut off, it can be switched on again after more than five minutes to avoid damage to the compressor or system. For maintenance, the power plug must be unplugged. After the refrigerator is installed in place, the plug should be accessible to prevent unplugging the power plug in time in case of danger.

(8) If the power cord needs to be lengthened, the cross-sectional area of the extension cord shall not be less than 0.75 mm. If the power cord is damaged, a special cord must be used. Contact the local after-sales service personnel of the refrigerator company to replace it.

(9) Do not put food in the freezer that has just been turned on. Let the empty display freezer run for a period of time (about 3 hours in summer and 2 hours in winter), and then put the frozen food in the freezer for storage and display.

(10) After the freezer is moved, it needs to stand for more than ten minutes before turning on the power.

(11) Clean the refrigerator regularly, and unplug the power plug before cleaning for safety. Regular dust removal of the heat exchanger in the replacement box can improve heat exchange efficiency and reduce energy consumption.

(12) Commercial freezers with mechanical defrosting should be defrosted regularly to avoid excessively thick frost and increase the energy consumption of the freezer. When defrosting, first transfer the goods in the display freezer, let it stand for a period of time until the frost layer has melted, and then use the defroster equipped with the freezer to remove the frost. Do not use sharp objects to defrost brute force to avoid damage to the inner wall of the freezer.

However, most of the display refrigerators in the current market can automatically defrost. Sanye refrigerators, as an old brand of commercial refrigeration equipment research and development and production in China for 15 years, have already mastered this technology.https://www.freezer-china.com/

Second，The clever use of the freezer.

(1) Soap re-hardness

After the soap is softened with water, it will become sticky and soft. It is quite inconvenient to use. It can be placed in the freezer of the freezer for about 30 minutes. The freezer can not only absorb the excess water in the soap, but also restore its hardness through the coldness.

(2) The candle does not drip wax

4 hours before using the candles, first freeze the candles in the freezer. After being ignited, cold candles will burn more slowly and longer, and they will not drip wax.

(3) Battery extension power

The standby time of the mobile phone battery is shortened due to memory or aging. The battery can be wrapped in newspaper, and the newspaper can absorb excess water. Put it in a plastic bag and put it in the freezer for 3 days. Take it out and leave it at room temperature for 2 days before charging. Repeat 3 to 4 times.

(4) Cut the egg yolk without breaking it

Freshly cooked boiled eggs or tea eggs with a knife, all the yolks are broken, and can be stored in the freezer for 1 hour.

Cut the egg yolk after it has cooled slightly. The cut is smooth and the egg yolk will not break.

(5) Remove the spicy taste

Cut the spices such as onion and green onion and garlic directly. The pungent taste will make you cry. You might as well put it in the freezer for 1 hour.

When the spicy substance is more stable, cut it again, and you won't be smoked and cry.

(6) When storing food in the freezer, there should be a gap of more than 10 mm between the food and the cabinet wall and between the food and the food, which is conducive to air convection and food preservation. The middle layer of the freezer especially should not be too full, because the best cooling position of the freezer is not the lower layer but the middle layer. If the middle layer is blocked without gaps, the cold air cannot circulate downwards, so that the food in the lower layer is also prone to spoilage.

(7). For fruits such as bananas and pineapples, if they are stored in the freezer for a long time, the pulp will deteriorate or the skin will turn black, so refrigerate them for a short time before eating.

(8) When using a freezer, try to reduce and shorten the time and frequency of opening the door, especially in summer. If the number of openings is too much or too long, the food will become hot and cold, which will affect the storage quality. In the hot summer, the freezer is most afraid of power outages. Over time, the food in the freezer will thaw and deteriorate. Fill a small-capacity plastic bag with fresh water and freeze it into ice cubes, and keep it in the freezer to prevent food from spoiling due to the temperature rise in the freezer during power outages.

(9) Apply a layer of talcum powder or talcum powder evenly on the surface of the freezer door seal and where the cabinet is in contact with the door seal, which can prevent the paint on the door frame from being pulled off by the seal and make the door open and close flexibly Freely extend the life of the door seal.

(10) Wipe the eggs with a warm cloth and put them in the freezer with the big end upright, which can also keep them fresh for a long time.

(11) The seeds of a variety of indoor flower plants are stored in an environment at ordinary room temperature, and they will lose their ability to germinate over time. If it is placed in a freezer cold room, when the temperature is 7°C, it can be stored for 60 days.

(12) Put clean plastic wrapping paper in the freezer to avoid sticking.
