Patent ID: 7963216

Claim:
An apparatus for improving surface smoothness and internal firmness of cylindrical food products, comprising: a plurality of shaped cylindrical food products separately disposed on a surface of a conveyor belt so as to be moved horizontally and synchronously; a large roller provided at a front end of a conveyor and configured for active rotation so as to drive the conveyor belt to move forward horizontally and cyclically; and a small roller provided below an output end of the conveyor such that the small roller and the large roller jointly form a rolling zone therebetween; wherein a first said cylindrical food product transferred by the conveyor belt is output from an output end of the conveyor belt and falls into the rolling zone so as to roll in the rolling zone for an amount of time via rotation of the large roller and of the small roller, thus allowing a surface of the first said cylindrical food product to keep rolling and sliding on the surface of the conveyor belt and a surface of the small roller; and wherein a second said cylindrical food product transferred by the conveyor belt falls onto a lateral surface of the first said cylindrical food product, thereby pushing the first said cylindrical food product out of the rolling zone, such that the first said cylindrical food product output from the rolling zone has improved surface smoothness and increased internal firmness, as well as a clearly defined cylindrical shape.
