Pneumatic blanking device for areca nuts

A pneumatic discharging device for betel nuts comprises a feeding conveying device used for conveying incoming materials; the material treatment device is used for deeply treating the materials; the feeding clamping jaw is used for clamping the materials on the feeding conveying device, conveying the materials to the material processing device for processing, clamping the materials after the materials are processed, and loosening the clamping jaw in the return process; and the air blowing and discharging mechanism is located on the moving path of the feeding clamping jaw and is only used for starting air blowing when the feeding clamping jaw returns so as to discharge residual materials on the feeding clamping jaw. The automatic discharging device is compact and reasonable in structure and convenient to operate, can realize automatic identification and discharging in an air blowing mode in the return process after materials are processed, can avoid chippings generated by contact friction and influence on food
