The invention discloses a taper drum-type device for dehairing and grading of kiwi fruits with computer monitoring of a rotation speed, wherein a spacing between two taper drums disposed side by side constitutes a V-shaped dehairing room; a computer controls the rotation speed of the drums to ensure optimal uniform dehairing on surfaces of the kiwi fruits; the speed is increased when residual hairs are detected, so that the dehairing ability can be enhanced; the speed is reduced when the dehairing is conducted thoroughly, so that damage is avoided; when the kiwi fruits fall into the V-shaped chamber between the two taper drums, the kiwi fruits will be rotated at a gradually linear acceleration under the gravity and friction force effects of the two taper drums and will move towards large ends of the taper drums, and the linear speed keeps on increasing, so that the kiwi fruits can be rotated centrifugally without any extrusion or friction damage, and thus the dehairing and grading can be achieved through combination of centrifugal force and brushing effects of a soft brush. Creatively, the device disclosed by the invention is characterized in that the taper drums with implanted fiber fur are used for the centrifugal brushing dehairing of the kiwi fruits, so that the dehairing is thorough and no damage is generated; and a sine wave damping shock absorber can achieve damping and buffering effects and eliminate vibration energy, so that the service life of the device can be increased.
