Fully automatic large-scale commercial spherical popcorn machine can popcorn every 4 minutes/pot on average. The popcorn machine produces 5 kg of finished popcorn at a time. The advantage is that the capacity is large and the heating is fast. It is suitable for commercial use, and the pot body can be quickly separated from the heat source after the heating is stopped to prevent the high temperature residual heat from causing the pot to stick.
