Abstract
Description
Technical Field
[0001] This utility model relates to the field of foreign object detection technology, specifically a continuous multi-station food foreign object detection station. Background Technology
[0002] The main methods for detecting foreign objects in food include the following: Visual inspection: This involves direct visual inspection or the use of auxiliary tools such as magnifying glasses, optical inspection tables, and camera systems. This method requires less equipment investment but has poor detection results, is prone to missed detections, and cannot detect packaged products. Screening: This method uses vibrating screens, sieves, and pipe filtration to separate solid materials of different particle sizes or densities. This method requires less equipment investment and is simple to apply, but can only be used for liquid, powder, and small particle products, and cannot be used for packaged products. Magnetic separation: This method uses a magnetic separation system to remove metallic foreign objects from products. This method is suitable for separating magnetic metals but not for non-magnetic materials, and cannot be used for packaged products. Metal detection: This method uses a metal detector to detect metallic foreign objects in food. This method has high accuracy and efficiency and is suitable for different production processes and processing stages, but requires higher equipment investment and more extensive personnel training. X-ray inspection: This method uses X-rays to distinguish materials of different densities and detect physical contaminants such as metal fragments and glass fragments. This method is suitable for detecting various types of foreign objects, but requires higher equipment investment.
[0003] X-ray food foreign object detection machines are automated foreign object detection devices that have been widely adopted in recent years. Utilizing the penetrating power of X-rays, they can detect foreign objects in food (such as various meat products, seafood, fruits and vegetables, additives, milk powder, chocolate, etc.), including metals, glass, ceramics, stones, bones, and plastics; they can also identify product defects, such as packaging cracks and bubbles, and missing contents; achieving complete finished product inspection.
