Dry-type high-frequency coffee bean peeling device

Abstract

This invention provides a dry high-frequency coffee bean peeling device, comprising a processing chamber, a high-frequency energy generating unit, a residue removal unit, and a control module. The processing chamber has a dry processing space to accommodate the coffee beans to be processed. The high-frequency energy generating unit applies high-frequency energy to this dry processing space, loosening or removing residues from the surface of the coffee beans. The residue removal unit is connected to the dry processing space and discharges residues during or after the high-frequency processing. The control module controls the frequency, energy intensity, duration, and airflow parameters of the high-frequency energy. This invention can efficiently remove silverskin and peel residues in a dry environment, improving the cleanliness and roasting quality of the coffee beans.

Claims
