Artificial dog bone prodn. - from ground hide remnants, mixed with bonding agent e.g. gelatin and moulding

摘要

Artificial bones for dogs are made by grinding waste parts of hides and skins and by mixing the meal with a bonding agent. The mixt. of meal and bonding agent is then filled into a mould in the shape of abone. Pref. the hides or parts of them are first dried, broken to pieces of 1-2 cm. and ground to a particle size of 50-500 mu (120 mu). The meal is mixed with a bonding agent such as gelatin (from bones) soya bean germs or linseed, in wt. ratio of 50:50. The mixt. is cast into moulds or pressed with a force of 20 tonnes to the shape of a bone. This is a much more economical way than using strips of whole buffalo hide which have to be cut, soaked, preformed and pressed in a mould. The new method can be completely automated.
