Problems solved by technology

At present, the X-ray inspection system widely used in the production line is a visual inspection system. After finding unqualified products, the products are manually removed. Generally, there are the following problems: (1) The number of products to be inspected is very large, and the operator takes a long time to carry out inspections. Single and boring work causes visual fatigue, and it is prone to missed detection

Embodiment

[0088] This type of food ray detection method, such as figure 1 As shown, it specifically includes the following steps:

[0089] (1) The X-ray generating device 3 emits X-rays, so that the X-rays pass through the food to be tested 4;

[0090] (2) The CCD camera 5 receives the X-rays passing through the food under test 4 to form a CCD image of the food under test 4;

[0091] (3) control the image input module in the computer 1 to obtain the CCD image from the CCD camera 5;

[0092] (4) the CCD image is processed by the image information reorganization module, and is packaged into a processable image data format to form continuous image information;

[0093] (5) The detection module in the control computer 1 detects and recognizes the tested food 4 according to the image information, and makes corresponding alarm signals for the presence of cracked dough cakes, loss of material packages or presence of foreign objects.

[0094] In the step (1), the X-ray generator 3 is control...

Abstract

The invention provides a ray detection method for noodle food, which comprises the following steps of: (1) emitting X-rays by an X-ray generating device, and making the X-rays pass through the detected food; (2) receiving the X-rays passing through the detected food by a CCD camera to form a CCD image of the detected food; (3) controlling an image input module in a computer to acquire the CCD image from the CCD camera; (4) processing the CCD image through an image information reorganization module; and (5) detecting and identifying the detected food, and sending corresponding alarm signals in the presence of bread crack, seasoning loss or foreign matter. The invention also provides a ray detection device for the noodle food for implementing the method. The device comprises a food conveying device, an imaging device, a control circuit and a control computer, wherein an intelligent foreign matter identification system is arranged in the control computer. The method and the device can detect, identify and alarm the bread crack, seasoning loss or foreign matter of the noodle food, and have the advantages of safety, accuracy, high efficiency and the like.

Description

technical field [0001] The invention relates to radiation detection technology, in particular to a radiation detection method and device for noodle food. Background technique [0002] When food is processed and packaged, it is often mixed with some foreign matter, mainly including foreign matter such as metal, glass, stone, plastic and rubber. These foreign matter not only affect the quality of food, but also some foreign matter is difficult to detect with the naked eye and is easy to detect. Be eaten by consumers by mistake, causing food safety accidents. Therefore, before the processed food is sold in the market, it is necessary to check whether it contains metal or other contaminants or foreign matter. Traditional detection technologies include metal detectors, ultrasonic imaging detection, X-ray detection and other technologies. At present, the X-ray inspection system widely used in the production line is a visual inspection system. After finding unqualified products, ...
