Tomato Sorting Machine Design

Abstract

This design is based on the existing fruit sorting mechanism, and the sorting mechanism has been improved by using a spiral roller to design a tomato sorting machine. Based on the size of tomatoes, this tomato sorter can classify tomatoes into three categories to meet the needs of different occasions for different sizes of tomatoes, improve the utilization rate of tomatoes, and also speed up the rate of tomato sorting. The threads on the outer layer of the drum push the tomatoes forward while the drum rotates, and the tomatoes fall through the corresponding drum gaps to complete this sorting stage, with the largest grade going all the way to the end of the drum for grading. And the whole machine is equipped with sponge as a cushioning material in the parts of tomatoes that are easy to be impacted to prevent tomatoes from being damaged and to facilitate storage and sale of tomatoes. The sorter is inexpensive, easy to maintain and suitable for small-scale farmers.
