Technical Field

The invention relates to the field of pepper screening, in particular to an automatic screening device for fresh peppers.

Background

Capsicum, (school name: capsicum annuum l.) Capsicum is a annual or limited perennial herb. Fruits are generally conical or oblong, green in color when immature, and bright red, green or purple after ripe, with red being most common. The fruit skin of Capsici fructus contains capsaicin and has pungent taste, and can promote appetite. The content of vitamin C in capsicum is the first in vegetables, original mexico, and Ming dynasty last year is transferred into China. In recent years, the life quality of people is improved, the health care and disease treatment of people are expected to be put into food consumption, green food is advocated, and the peppers become green food favored by people in many areas and can be prepared into various convenient products such as pickled peppers, chilli sauce, oil peppers and the like.

In the industrial production process of the chilli product, procedures such as impurity removal, size grading, cleaning and the like are carried out on the chilli, and then the chilli can be subjected to subsequent processing treatment so as to ensure the quality of the final product.

The patent CN104384093B provides a pepper grader, which mainly comprises an inclined grading roller and a feeding, discharging and roller power device thereof, wherein the wall of the grading roller is provided with round holes and strip-shaped holes which are axially arranged in rows, and each row of round holes and strip-shaped Kong Jiaoti are arranged; the inner side of the joint of the round hole and the strip-shaped hole of the grading roller is provided with a parting bead, and the inner wall of the grading roller with the parting bead is smooth and alternately concave-convex wavy.
