Abstract

Abstract A dressing tool includes a rotatable tubular cutting member with an elongated probe member coaxially disposed therein. The probe member extends outwardly beyond the cutting member. The elongated probe is inserted into the anus of the poultry and a vacuum is drawn in the space between the probe and the cutting member. The cutting member is rotated to produce a circular cut around the anus and the tool is then pulled away from the carcass thereby removing the vent and alimentary canal a desired distance away from the carcass. The trigger of the tool is then released causing an air blow to occur between the probe and cutting member. In timed sequence, a wash cycle begins including a blowing period which is used to eliminate excess liquid from the probe and cutting member. Another feature of the invention is the use of a vacuum draw limiting member disposed on the probe for limiting the distance the vent is pulled into the cutting chamber between the probe and the cutting member.
