Abstract

PURPOSE: To provide a device which is provided with a cylinder in a leaching tank for fish meat and is provided with a perforated disk and rotary agitating vanes therein and is capable of efficiently degreasing the fish meat with a small volume of water. CONSTITUTION: The cylinder 4 is disposed in the leaching tank 15 and a raw material supply pipe 3 is connected to the middle thereof. The cylinder 4 is internally provided with the perforated disk 5 in the bottom end position of the juncture of its pipe 3 and is provided with the rotary agitating vanes 7 apart a slight spacing above the disk. The cylinder 4 is internally provided with the rotary agitating vanes 8 on the slight lower position from bottom end position as well. The fish meat from which extraneous materials, such as bones and skins, are removed, is guided together with water from a pump 1 through a valve 2 into the cylinder 4 from the pipe 3. The fish meat is crushed between the perforated disk 5 and the agitating vanes 7 and is subjected to leaching by the water flow generated by the agitating vanes 7. While the fish meat falls in the cylinder 4, the fish meat is subjected to the leaching (sepn. of fats) and accumulates in the bottom 14 and side parts of the tank 15. The leached fish meat is discharge by a siphon system from a discharge port 10 and the fats are discharged from a discharge port 13 by overflow.
