The primary consideration when choosing a commercial popcorn machine is the volume of popcorn you'll serve. Some countertop or cart-mountable models can pop as few as 4-20 ounces at a time, making them ideal for smaller venues like school concession stands and snack bars. If you're serving the masses in a movie theater or sports arenas, a 28 ounce up to a double 48 ounce popper will easily provide the output you'll need.
The frames for these industrial popcorn machines may be made of aluminum or stainless steel. The cabinet will be constructed of either tempered glass or plexiglass, but the doors will typically be made of plexiglass making them lighter for easier accessibility. They often have vibrant graphics, helping to stimulate impulse buys. Countertop commercial popcorn machines can also be mounted on carts, making them ideal for marketing. The larger versions often have bases to provide ample storage for unpopped corn, oil, and packaging.
