[0003] An elevator is a large-scale mechanical equipment that transports fruits by changing their potential energy. In the production of dried fruits, the dried fruits need to be lifted according to the processing flow of the dried fruits so that they can be transported to the processing machine. As the processing steps of the dried fruits are added, the dried fruits become brittler in the later processing steps and are prone to break into small pieces during operation, affecting their quality and selling price. In addition, dried fruits are generally small in size and are easily shaken off due to vibration during transportation.
