A thermos can temporarily keep ice cream warm, but it is not recommended to use it for a long time to store ice cream.
1. The insulation principle of thermos cups
The insulation principle of a thermos cup is to use a double-layer stainless steel cup body and a vacuum layer in the middle to isolate the external temperature and prevent heat transfer. So thermos cups are suitable for storing hot drinks such as coffee, tea, and milk, but not suitable for storing cold drinks such as ice water and ice cream.
2. Can a thermos keep ice cream warm
Although a thermos can isolate the external temperature and prevent heat transfer, the situation is different when we put ice cream in. The temperature of ice cream is very low, usually around -18 ℃. When we put it in a thermos, due to the material and volume of the cup, the insulation effect is poor, so the thermos can only temporarily keep the ice cream warm. If we want better insulation effect, we can consider using specialized insulation tools such as insulated boxes or insulated ice packs. In addition, using a thermos for a long time to store ice cream not only fails to keep it warm, but also easily causes contamination of the cup, affecting health.
3. How to preserve ice cream
If we want to store ice cream at home, we can choose a dedicated ice cream refrigerator or freezer for storage. These devices usually have better insulation and storage capacity, and will not affect the storage of other food in the home. In addition, to preserve the taste and quality of ice cream, it is recommended to store it in a dry, dark, low temperature, and odor free environment. Do not frequently open or close the refrigerator door to avoid temperature changes and bacterial contamination.
4. Conclusion
A thermos can temporarily keep ice cream warm, but it is not recommended to use it for a long time to store ice cream. If you want better insulation effect, you should choose specialized insulation tools. To preserve ice cream, it is recommended to use an ice cream refrigerator or freezer.
