Chill cold: isothermal bag
At the dawn of the 21st century, the problem of preserving the freshness of products remains as important as a hundred years ago.This question is especially topical for fans of long-distance travel. How to keep foods benign, so they can have a snack on the road?
At the end of the last century, a way out was found. There is a special isothermal refrigerator bag. What does this device represent? And how does it work?
Such a bag (isothermal container) is simply necessary if you want your products to remain fresh as long as possible. Most often it is used for cooling or storage of frozen semi-finished products. But there are cases when it is used to keep dishes hot. In the people, such models are called a refrigerator bag, but this is not entirely true. Any refrigerator has a cooling device. The isothermic bag is devoid of it. It performs its functions due to the accumulator of cold. Over time, the temperature inside becomes the same as the ambient temperature. How long the bag will keep products frozen, depends on its technical characteristics. As a rule, larger containers better save the cold.
All the useful properties of a thermos bottle depend on the cold accumulator.This is a plastic briquette in which a special salt solution is poured. The more such devices in the container, the longer it keeps the temperature low. Without an accumulator, an isothermal bag can hold the cold for up to 3 hours, with which it can be substantially increased.
What are the advantages of this model?
- The isothermic bag can support both cold and hot temperatures.
- Compactness and mobility are two components that make this subject so popular.
- Excellent design, many bags look very exquisite and presentable.
- Reliable protection. All kinds of lightning, visors help keep the food intact. Protective locks securely fix them inside, preventing the possibility of accidentally opening the bag.
- Internal convenience. Usually inside the bag there are several compartments. For example, for cans or bottles. And some of them have a set of utensils in the set. All this helps to arrange the products easily and conveniently.
And, perhaps, the most basic question: "What should I look for when choosing such a model?"
First of all, if you are interested in an isothermic bag, determine the volume. Their capacity varies from 5 to 30 liters. For a normal family, a medium-sized container is enough.
The second important factor is the material from which the isothermic bag is made. Usually nylon, plastic, polyester is used for this purpose. They are durable and easy to clean. It is desirable that inside there is a PVC material with reflective properties.
Next, pay attention to the convenience of transporting the bag. She should have special pens. In case you stayed on a fairly roomy model, the bag should be equipped with roller wheels. Otherwise, transfer it, and even filled with a large number of products, can be difficult.
Immediately in the store, check the reliability and safety of the carrying. The main thing is that the bag does not open spontaneously. To do this, there must be special security locks.
If you carefully examined the goods and you are satisfied with everything in it, feel free to buy a thermos bottle. She will serve you for many years with faith and truth.
