Procedure for removing the layer of hairy elements from a complete animal skin

Abstract

The present invention is drawn to a method of removing hair from an animal pelt in which liquified gas is applied to the fleshy side of the pelt to freeze the pelt to a temperature at which hair pores of the skin open. The application of the liquid gas to the pelt may be facilitated by placing the pelt on a conveyor having perforations, applying suction to the pelt through the perforations to secure the pelt to the conveyor, and applying the liquified gas to the pelt through the perforations. Furthermore, the application of the liquified gas to the pelt may be carried out in two phases. In the first phase, the pelt is frozen to a temperature between 0.degree. and -20.degree. Celsius. In the second phase, the pelt is frozen to a temperature between -20.degree. and -220.degree. Celsius. Finally, after the pelt has been frozen, the hair may be removed with an appropriate hair removing device such as a comb, blade or brush.
