Cold storage batteries - a very convenient device, indispensable in a hike or a long trip. They keep food for a long time, do not let them spoil during the hot season. The cold accumulator is a small, flat, sealed container filled with a special compound that quickly freezes. Such a reusable device allows not only to cool, but also to accumulate cold in auto-refrigerators, isothermic bags. For a refrigerator bag, a cold storage battery is used as the main cooling element.
Types of cold storage batteries
Currently, three types of cold storage batteries are produced: gel, water-salt and silicone. They differ in the types of filler. The gel cooler is made of a dense film with a special gel inside. It can both maintain a lowered temperature, and maintain an elevated temperature. The water-salt accumulator is a plastic container with saline solution, it maintains the temperature in the range from -20 ° C to + 8 ° C. Silicone cooler is a pack of strong plastic film with filler, which includes silicone. Such a battery maintains a temperature of 0-2 ° C, but for a long period (up to 7 days). This is its advantage over two other types of coolers.
How to use a cold accumulator?
As a rule, a cold battery works very simply. Before use, it should be placed in the freezer for a long time to completely freeze the filler inside the device. After that, put it in an isometric bag and the battery will be about 20 hours (depending on the model of the bag) to keep the cold, taking away the heat from the products in the bag. Then the cold accumulator should be washed with water and again put in the cold. A cold storage battery is made of a refrigerator bag made of environmentally friendly materials, absolutely harmless for food products. You can store such batteries in the freezer compartment of the refrigerator or in another, dark place. The lifetime of these devices is not limited with proper storage. Depending on the size of your refrigerator bag and the number of products in it, you may need not one battery, but several. If you use one cooler, then put it on top of the products, and if several, then shift them layer by layer all that is in the bag, and put one more on top.
Cold accumulators are also used in domestic refrigerators . They stabilize the temperature in the freezer compartment of the refrigerator, thereby contributing to a more rare on-off compressor. In addition, the cold storage battery increases the time for safe storage of products, if suddenly the electricity is turned off and the refrigerator does not work. Approximately up to 18 hours in the freezer will still remain below zero temperature. Also this device increases the capacity of freezing in freezers. When manual defrosting the refrigerator is very convenient to use cold storage.
Cold accumulators are used in heat chambers when selling ice cream or during the transportation of perishable foodstuffs.
How to choose a cold storage battery?
Today, the stores have a large selection of cold storage batteries from various manufacturers. The devices with a gel filler are very popular - they keep the cold longer and do not unfreeze. In addition, you should pay attention to what the container is made of: whether it will leak during use. Cold storage batteries are manufactured in a variety of sizes: from 250 ml to 800 ml or more. Therefore, depending on your needs, you can select the required number of cold storage devices, then your reserves will not be afraid of heat, and you can safely go on a trip.
