Abstract: A method and apparatus for the treatment, such as anaesthetization or killing, of poultry by using gas. The gas comprises oxygen and carbon dioxide, among other components. During the treatment, the oxygen concentration is kept constant at a normal level (18-22 vol. %). This is important as it allows the poultry to breathe normally while the natural body functions can be maintained in their normal state until anaesthetization takes place. The concentration of carbon dioxide is increased either continuously or discontinuously. Accordingly, it is possible to anaesthetize poultry before slaughter in a way which produces low levels of stress and discomfort in the poultry while, at the same time, the quality of the meat is better than with the use of traditional methods. In the apparatus, the poultry are exposed to the gas in a chamber (1). The apparatus may include a belt conveyor (5) and can be separated into three treatment zones (2, 3 and 4).

Abstract: The invention relates to a method for the evisceration of carcasses conveyed on a slaughter line suspended in gambrels or hooks, where the abdomen and breast have been cut open, the hams divided and the fat end loosened, and wherein the carcass intestines are loosened, removed and placed on a gut pan or conveyor, the diaphragm is loosened and the plucks are removed and placed on a plucks conveyor. In loosening of the intestines, the connections of the intestines with the spinal column are broken, so that the intestines are made to hang out of the abdominal cavity. The diaphragm and leaf fat are loosened mechanically while the intestines are hanging out of the carcass and are connected to the plucks. The latter loosening is effected by a pressing device (5) and a hoop device (6) which can be moved independent of each other in the lengthways direction of the carcass.

Abstract: A coin conditioner is provided for cleaning or otherwise conditioning coins in a coin discriminator apparatus prior to transfer to a coin sensor.
