The ice box is a container used to keep food fresh. It uses special insulation materials and sealing design, which can effectively isolate the outside temperature and air, and extend the preservation time of food. The fresh-keeping ice box is usually composed of an inner liner, a shell and a sealing device, and the shape is mostly rectangular or square, which is easy to carry and store.

Size

1. Appropriate size: Choose the right size according to your needs, do not choose too large or too small fresh-keeping ice box, so as not to waste space or cannot accommodate the required food.

2. Excellent material: Choose the fresh-keeping ice box made of high-quality insulation materials, which can better maintain the temperature and humidity of food and ensure the freshness of food.

3. Good sealing performance: Ensure that the sealing performance of the fresh-keeping ice box is good, which can effectively prevent the air and external temperature from entering, and avoid food contamination or deterioration.

Usage

1. Clean the fresh-keeping ice box: Clean and disinfect the fresh-keeping ice box before use to ensure that there is no odor and bacteria inside. It can be wiped with a mild cleaner and water, and used after drying.

2. Pre-cooling or heating: In order to better maintain the temperature of the food, the fresh-keeping ice box can be pre-cooled or pre-heated in the refrigerator before use, so that it reaches the desired temperature.

3. Reasonable arrangement of food: When putting food into the fresh-keeping ice box, the size and shape of food should be reasonably arranged to make full use of space. At the same time, you should avoid putting fragile or leaky food directly into the fresh-keeping ice box, and you can use a sealed bag or plastic wrap for secondary packaging.

4. Pay attention to tightness: After putting food into the fresh-keeping ice box, ensure that the lid is tightly sealed to avoid air and moisture entering. It can be reinforced with sealing tape or other sealing devices as needed.

5. Timely consumption of food: the fresh-keeping ice box can only extend the fresh-keeping time of food, and cannot maintain the freshness of food without limitation. Therefore, when using the fresh-keeping ice box, food should be consumed as timely as possible to avoid long-term storage.
