Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a peanut shelling device. Background Technology

[0002] A peanut threshing device is a mechanical device that separates peanut pods from the vines while maintaining their integrity. It primarily utilizes mechanical force to break the connection between the vines and pods, and separates different components through screening and airflow. For example, Chinese utility model patent CN213280718U discloses a peanut threshing machine, belonging to the field of agricultural production equipment technology. This utility model uses threshing teeth to remove peanut pods from the vines, and uses a mesh screen, a separating screen, and a dust removal fan to remove peanut vines and attached soil, reducing impurities after threshing. The mesh screen is detachable via buckles and hooks for easy cleaning of peanut vines inside the threshing machine. A dust collection bag is installed at the outlet of the dust removal fan to collect soil, reducing the difficulty of cleaning the peanut threshing machine and improving the efficiency of the threshing process.
