Does the small household popcorn maker need to be preheated before first use?

Before the first use of a small household popcorn maker, it is indeed necessary to preheat it empty. Here are some key points to explain:
1. Eliminate production residues: During the production process, equipment may have some oil, chemical residues, or other substances. Preheating the machine can help to heat and evaporate these residues, avoiding them from affecting the quality of subsequent food.
2. Check device functionality: Preheating can help users check whether the device is functioning properly, such as heating speed and noise level, to ensure that the popcorn machine does not have any problems during normal use.
3. Stabilize the heating element: During the first use, the heating element inside the machine may be somewhat unstable. Preheating can help the heating element gradually adapt and extend its service life.
4. Avoid machine damage: If corn kernels are directly put into popcorn making, it may cause excessive circuit burden due to incomplete adaptation of the machine, affecting the lifespan of the equipment. The preheating process helps to reduce this risk.
5. Removing odors: Sometimes new machines may have some plastic or grease odors, and preheating the empty machine can help remove these odors.
