For cafeterias, food courts and other food service applications requiring plastic meal trays, these tray racks are an important addition to your kitchen equipment. Made with durable swivel casters and long-lasting aluminum or stainless steel construction, these tray racks are ideal for holding soiled food trays before they go through the dishwasher. Tray racks resemble pan racks in appearance and utility, and in fact you may be able to swap them out without too much trouble. However, tray racks are designed especially to collect dirty cafeteria trays and bring them all at once to the commercial dishwashing station. Choose a rack depending on the volume and size of your dining area. For instance, if you run a college campus dining hall servicing thousands of students every day, the bigger the tray rack, the better. Students and other diners often load their own trays into these racks after they are finished with their meals, or workers can take this job, depending on the operation.
