Automatic food screening equipment

Abstract

According to the automatic food screening equipment, when semi-finished products fried in the previous process are conveyed to a vibrating screen, the semi-finished products are evenly scattered to a conveying belt under the vibration effect of the vibrating screen, the conveying belt drives the semi-finished products to move forwards in the direction of a qualified product collecting line at a constant speed, and when the semi-finished products move to the position below an image sensor, the semi-finished products are conveyed to the image sensor. The image sensor collects image information of a semi-finished product and then transmits the image information to the image processor for geometric dimension and color analysis processing, when the image information does not accord with a set value domain, the image processor transmits the information to the central processor, the central processor sends out an instruction to open the high-pressure gas nozzle, and under the action of gas sprayed by the high-pressure gas nozzle, the semi-finished product is processed. The original running track of the semi-finished products which do not meet the requirements is changed, the semi-finished products fall into the rejected product collecting line in advance, and qualified products run to the tail end of the conveying belt, fall into the qualified product collecting line along a parabola track and are transferred to the next procedure. Therefore, the sorting work of the semi-finished products is completed by the food sorting equipment.

Description

Technical Field

[0001] The utility model belongs to the field of food screening automation equipment. Background Art

[0002] Fried foods on the market, such as crispy pork and meatballs, are all finely packaged when they enter stores for sale. At present, most fried foods are manually screened, and products that do not meet the required specifications in appearance, size and color are removed and screened before packaging. The screening process is mostly manual. This operation method has the following disadvantages: 1. It increases the chance of contact between humans and food, which increases the chance of food contamination; 2. Low labor efficiency and high cost; 3. It is not easy to unify product quality standards due to human subjective sorting. To this end, we have developed an automated food screening equipment based on market demand to meet market demand. Summary of the invention

[0003] In order to overcome the above defects, the utility model proposes an automatic food screening equipment, which is composed of an image sensor and a pneumatic rejection mechanism. It can automatically reject products whose geometric dimensions do not meet the set specifications and whose colors do not meet the specified requirements, and retain products with qualified dimensions and colors for the next process.

[0004] The technical solution adopted by the utility model to solve its technical problems is a kind of food screening automation equipment, characterized in that the structure includes a vibrating screen, a conveyor belt, an image sensor, a high-pressure gas nozzle, a rejection product collection line, a qualified product collection line, an image processor, and a central controller; the vibrating screen is adjacent to the conveyor belt and transports the products to the conveyor belt evenly; an image sensor is arranged above the conveyor belt; the image sensor is connected to the image processor; the image processor is connected to the central controller; the central controller is connected to the high-pressure gas nozzle; the high-pressure gas nozzle is arranged above the end of the conveyor belt; the rejection product collection line and the qualified product collection line are arranged at the end of the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0008] The machine is started. When the semi-finished product fried in the previous process is conveyed to the vibrating screen (1), the vibrating screen (1) evenly scatters the semi-finished product onto the conveyor belt (2) under the action of mechanical vibration. The conveyor belt (2) drives the semi-finished product to move forward in the direction of the qualified product collection line (6) at a uniform speed. When the semi-finished product runs to the bottom of the image sensor (3), the image sensor (3) collects the image information of the semi-finished product and transmits it to the image processor (7) for geometric size and color analysis. When the geometric size or color of the semi-finished product does not conform to the set value range, the image processor (7) transmits the information to the central processing unit (8). The central processing unit (8) issues an instruction to open the high-pressure gas nozzle (4). Under the action of the gas ejected from the high-pressure gas nozzle (4), the semi-finished product that does not meet the requirements changes its original running trajectory and falls into the rejection product collection line (5) in advance. The qualified product runs to the end of the conveyor belt (2) and falls into the qualified product collection line (6) in a parabolic trajectory and is transported to the next process. In this way, the food sorting equipment completes the sorting work of semi-finished products.
