<p>The problem of quick, efficient and simple skin removal from slaughtered animals, e.g. oxen, pigs, sheep or goats, is solved by scraping, using the machine and the procedure according to the invention. By positioning the body of the previously slaughtered and pretreated animal in an approximately vertical position in the machine, and by applying the required mechanical force i.e. strain, providing suitable speed of scraping, it is obtained that the skin remains in one piece, undamaged and free from fat tissue from the inner side. With simple modifications the machine can be built-in into existing plants regardless of their size or age. By utilisation of the machine, removing of hair from the skin by scalding and singeing is no more necessary. Considerable savings in time and space necessary for the animal treatment to the phase of finished and treated sides are accomplished, which increases a slaughterhouse capacities. The factor of animal utilisation is increased due to the fact that the skin and lungs, and at some animals the fur too, can be completely used as a material for further processing. The consumption of electrical energy, gas and water, needed for the classical process of scalding and singeing, is considerably reduced, as well as are the problems due to environmental pollution by organic waste.</p> |
