Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dried fruit detection, and particularly relates to a foreign body detection machine for dried fruit processing. Background Art
[0002] Dried fruit is a food made from fresh fruit that has been sun-dried or dried. Its moisture content is less than 12%, making it easy to preserve and suitable for direct consumption or for use in food preparation. Dried fruit needs to be packaged after production. After packaging, the dried fruit needs to be inspected for foreign matter, which can affect the quality of the dried fruit. Traditional foreign matter detection equipment mostly uses a single detection method, such as visual inspection, metal detection, or screen filtration. These methods can often only perform inspections from one or a few angles, making it difficult to achieve full coverage of the interior and surface of the dried fruit, resulting in a high missed detection rate. Traditional detection equipment often lacks flexibility during transportation and cannot dynamically adjust according to the size of the dried fruit. This may lead to problems such as dried fruit accumulation, squeezing, or slipping during transportation, which not only affects the detection effect but may also damage the dried fruit.
