MUNOZ M, DEYANIRA; DIAZ, NADY CAROLINA  e  CABRERA C, GERARDO. EFFECT OF TEMPERATURE AND SPEED OF THE HANGING LINE ON THE PERCENTAGE OF FEATHER AND DEPIGMENTATION OF WHITE AND PEN CHICKENS, DURING THE SCALDING PROCESS. Rev.Bio.Agro [online]. 2011, vol.9, n.1, pp.69-76. ISSN 1692-3561.

This research aims at analyzing the effect of temperature and speed of the hanging line on the percentage of feather and depigmentation of white and pen chickens during the scalding process. The operation values of scalding temperature of and speed in accordance with the standards of quality stipulated by INVIMA, were 54 to 58°C and 110 to 130 units per minute for white chickens, and 51 to 53°C and 90 units per minute for pen chicken. Under these conditions, less than of 10% of feather, 1% of over scalding level and a depigmentation percentage inferior to 26%, were generated in both white and pen chickens.
