In the hot summer, watermelons can be seen everywhere in supermarkets and fruit stalls. I can't help but buy a few. However, the watermelon that can't be eaten is covered with plastic wrap, and it is a bit odor after being put into the refrigerator. Today, I would like to share with you a good way, no need for a refrigerator, and the watermelon that can't be eaten is kept for two days.
The correct preservation method of watermelon
1. Only need plastic wrap, or food bag in the supermarket, and then prepare a basin of cold water.
2. Wrap the watermelon with plastic wrap and then use a toothpick to poke some small holes in the cling film.
3, slowly put the wrapped watermelon into the cold water (Note: water can not exceed the surface of the watermelon), so it is not a problem to put it for two days, this preservation method is similar to the principle in the release.
When you want to eat again, first cut off the top layer of the watermelon, so the taste will be better. However, it is recommended that everyone, watermelon is still eaten now, if you put the refrigerator, it is best not to exceed 24 hours.
Watermelon + plastic wrap = bacteria?
In fact, watermelon covered with plastic wrap may have been contaminated before being placed in the refrigerator. The speed of bacterial reproduction depends on two points, one is the degree of contamination of the food, and the other is the preservation environment of the food.
Watermelon covered with cling film is easy to breed bacteria, which can not be seen as a problem of cling film. Because cutting a watermelon knife, a chopping board, or a bag containing watermelon, it is possible to cause a large amount of bacteria to grow before the watermelon is placed in the refrigerator. Therefore, it is not just a problem with cling film.
Busway Temperature Monitoring System
The busway temperature monitoring system is composed of monitoring host and temperature and humidity acquisition module, which is used for the temperature monitoring of low-voltage dense busway. The main monitoring temperatures include: the temperature at the busway connection (the temperature of each phase contact point), the busway housing temperature, and the ambient temperature, and can display, upload, store and fault alarm the data in the monitoring unit.
