| 20090056697 | Direct-heating type carcass processing apparatus using vacuum - A direct-heating type carcass processing apparatus using vacuum. At least one piece of dead livestock infected with various diseases such as infectious diseases is heated for complete sterilization using high-pressure steam, and undergoes complete moisture removal to become dry by means of the vacuum, thereby allowing the dead livestock to be easily crushed. To this end, a carcass processing drum is directly heated by a heating means instead of a conventional steaming process, which provides steam from a boiler to the dead stock, to reduce a processing time and cost due to removal of the boiler. The vacuum can be converted into atmospheric pressure using a pressure valve so that the processed dead livestock can be discharged from the apparatus. | 03-05-2009 |
