Those who pretend to be manufacturers feel like those who think they are experts. First of all, the domestic garbage ice cream machine adopts capillary interception, which is similar to the refrigeration principle of refrigerator. I won't criticize those manufacturers here. Their machines can only be kept indoors. If the temperature outside is good, it will seriously reduce production, and it is very likely that ice cream will not be made. A good ice cream machine uses an expansion valve, and the first refrigeration speed is fast. After testing for 6 minutes, the 220-power ice cream machine can be finished, and the 380-power ice cream machine is faster, which is an improvement on the refrigeration principle of the refrigerator. Therefore, the typical feature of this machine is high temperature in summer, which will not greatly reduce production. As for more details, I won't say much.
