Volterson 3 Step 4 Slice Electric Sandwich Griller For Hotels and Restaurant

This indicates the griller's ability to cook four standard-sized sandwiches simultaneously, making it ideal for high-volume settings like cafes, restaurants, or food stalls. The "3-step" likely refers to variable temperature or heat settings. This allows users to adjust the grilling intensity based on the type of sandwich and desired level of toasting. This may be low, medium, and high heat settings. Or it could be that there are three distinct levels of pressure that can be exerted by the top plate of the grill. These are typically made of cast iron or aluminum with a non-stick coating (like Teflon) to prevent sandwiches from sticking and to facilitate easy cleaning.
