Abstract: 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.

Abstract: A developing unit includes a waste toner housing having an upper housing and a lower housing which face each other, at least one support unit to allow connection between the upper and lower housings, and to support facing surfaces of the upper and lower housings, and a toner housing which is disposed on a lower part of the waste toner housing and is spaced apart from the waste toner housing at a predetermined distance. Accordingly, the waste toner housing is prevented from being deformed by heat and pressure, and thus white lines on images, flowback of waste toner and insufficient cleaning, which are caused by interference with the light path due to deformation of the waste toner housing, can be reduced. Additionally, tolerance can be greatly reduced as a result of resolving the problem of deformation of the waste toner housing, so a developing unit having a smaller size can be provided.
