美国采购需求：棉花糖机，全自动棉花糖机，SC-320棉花糖机

I'm looking for a high-capacity cotton candy machine that offers a variety of options for shapes and characters. The machine should be able to handle large volumes efficiently, as I anticipate significant demand. It's essential that the designs are versatile, allowing for creativity in serving different themes and occasions. Additionally, I'm interested in features that enhance usability and safety. If you have any models that come equipped with user-friendly controls and safety mechanisms, please include that information. I would also appreciate details on the machine's performance, maintenance requirements, and available customization options.
