Field of the Invention The present invention relates to a pig carcass processing unit which prevents contamination during carcass processing and provides a sanitary processing environment. [0002] Conventionally, meat centers have slaughtered and processed livestock such as pigs into meat. As for the pig, as a pretreatment step, the pig is driven into the slaughter room, slaughtered by electric shock, the carcass is hung on a hanging trolley, and pretreatment such as exsanguination and emptying is performed. Processing such as removal of crushed bones, washing with water, and cooling is performed manually by humans. [0003] However, according to the conventional methods, the outer skin peeled off at the time of peeling the pig and the carcass after peeling the outer skin come into contact with each other or the slaughter suspended on a trolley. The bodies contacted each other, causing the meat to become contaminated. Accordingly, the present invention has been made to solve the above problems, and it is an object of the present invention to provide a highly safe pork slaughterhouse that eliminates contamination during carcass processing that is a problem in food hygiene. With the goal. [0004] In order to attain the above object, the present invention as defined in claim 1 is characterized in that at least a pig carcass skin after a pretreatment step is rolled downward by a roll. A trolley that includes a down-roll type automatic peeling machine according to Japanese Patent Application Laid-Open No. 8-89160 and an automatic cleaning spine splitter that separates and cleans the carcass of the carcass, transports the carcasses in a non-contact hanging state, Discharging means for carrying out the outer skin outside the processing chamber, exhaust means for guiding the air inside the processing chamber to the outside, fountain means for cleaning the separated carcass, hot water tank for supplying hot water to the fountain means, A pig carcass processing unit comprising a drain for discharging washing wastewater and a hydraulic device for driving the automatic peeling machine and the automatic washing spine splitter.

When the skin is peeled off, electricity is supplied through the electrodes 22 so that the muscles of the carcass M are stiffened and the skinning process is facilitated. The outer skin fixed by the clamp 16 is separated from the carcass M by the rotation roller 17 being rotated by the hydraulic motor 18 and the lifting table 19 holding the rotation roller 17 being lowered together with the hydraulic cylinder 20. Done. The peeled skin of the carcass M falls off by releasing the clamp 16 and reversing the rotating roller 17, and falls into the air shooter 23 provided below the rotating roller 17, thereby leaving the processing chamber 2. It is carried out. At the end of the peeling process, the power point 7c is turned on, and the trolley 7 suspending the carcass M is made movable,
The carcass M is transported to a position where the rotary cutter 28 of the automatic spine splitter 25 is installed. Next, the hydraulic cylinder 26b of the foot presser 26 installed facing the rotary cutter 28 extends, and the carcass M in which the foot fixing portion 26a installed at the tip of the hydraulic cylinder 26b is suspended moves the carcass M in an immobile state. I do. The carcass M is a rotary cutter 2 driven by a hydraulic motor 29.
8, the lifting table 30 holding the hydraulic motor 29 and the rotary cutter 28 is moved up and down by the hydraulic cylinder 31, thereby executing the spine splitting process. At the time of the spine splitting process, water is discharged from the fountain portion 27b installed on the panel 27a of the automatic fountain means 27 installed on both sides of the automatic spinning device 25, and the rotary cutter 28 and the carcass M Chips adhering to the cross section are cleaned and removed, and heat generation of the rotary cutter 28 is also prevented. Water for washing is supplied from the water tank 27c,
Water is sent to the pipe 27e by the pump 27d. The carcass M after the back splitting process is carried out of the processing chamber 2 by restarting the trolley 7. The air in the processing chamber 2 is constantly circulated by the ventilation means 4 to keep the processing environment suitable. At the end of the operation, steam of 83 ° C. or higher is released from the steam generating section 34 a of the hot water tank 34, and the processing chamber 2 is sterilized. The cleaning wastewater is discharged to the outside of the processing chamber 2 through a drainage groove 14 provided in the floor 13. According to the present invention, the processing chamber 2 can be expanded by additionally providing the casing 3.
This will be described below with reference to FIG. (Embodiment 2) FIG. 3 shows Embodiment 1 of the present invention.
