Various aspects of this disclosure relate to a method of trimming a cone-shaped wafer, wherein the trimming is performed with an ultrasonic knife. The cone-shaped wafer may be an ice cream cone such as a waffle cone. In some specific embodiments, the cone-shaped wafer is trimmed to a length of no greater than 117 millimeters.

A food wrapper filling system for use with edible or non-edible food wrappers. The system includes a funnel device portion and a stand portion. The stand portion is placed over the food wrapper item and the funnel device is inserted into a receiver within the stand. Food ingredients are placed into the funnel device through a throat and opening through the funnel device, and the ingredients are stacked neatly without spillage or mess within the food wrapper. Sizing plates or funnel inserts can be used to limit the amount of space within the funnel device that ingredients may be added into for use with smaller sized food wrappers.

An automatic sandwich maker designed to automate the process of preparing sandwiches, including hamburgers, is included. This automated sandwich maker is designed for use in commercial kitchens, including small commercial kitchens, such as fast-food kitchens. The apparatus and method for automatically making sandwiches overcomes the drawbacks and limitations of the prior art. The individual sandwich process can be controlled by communications interface with a point of sales system. The inventive apparatus and method reduces manpower requirements for restaurants, provides enhanced ingredient control, and improves overall product quality.

A system for forming sandwich products, including a first conveyor for supplying a plurality of flat baked goods, wherein the plurality of flat baked goods is divided into a first group oriented facing downwards, and a second group oriented facing upwards; a second conveyor for supplying the viscous edible material; temperature control system disposed onto the second conveyor and arranged to achieve a predefined viscosity level of the viscous edible material; a first robotic manipulator configured to pick up the viscous edible material from the second conveyor after its viscosity has been adjusted to the predefined level, and to deposit the viscous edible material onto flat baked goods of the first group; a second robotic manipulator configured to pick up and place flat baked goods of the second group onto the viscous edible material deposited on the flat baked goods of the first group, thereby forming the sandwich products.
