Description

Technical Field

[0001] The utility model relates to a defective product rejecting device, belonging to the field of fruit processing. Background Art

[0002] Fruit processing uses fruits and berries as raw materials, treats them by physical, chemical or biological methods (inhibiting the activity of enzymes and the activity of spoilage bacteria or killing spoilage bacteria), and then processes them into food to achieve the purpose of preservation. Fruit processing can improve the flavor of fruits, increase their edible value and economic benefits, and effectively extend the supply time of fruits. When fruits are produced and processed on a large scale, they need to go through processes such as washing, fruit sorting, and inferior fruit selection. In the process of inferior fruit selection, workers need to pick out the inferior fruits. For this purpose, it is necessary to use inferior product rejection devices to reject and distinguish smaller fruits.

[0003] In the prior art, when processing fruits, it is necessary to remove smaller inferior fruits according to the size of the fruits. Because there are many kinds of fruits on the market and there are certain differences in the sizes of fruits, in the process of screening using sieves, due to the different sizes of fruits, it is necessary to replace sieves with different mesh sizes for removal operations. Therefore, when the machine is screening, the sieve needs to be disassembled and replaced according to the type of fruit, which affects the processing speed. Therefore, it is necessary to design a defective rejection device that can automatically change the size of the sieve holes according to the size of the screened fruit. Utility Model Content
