<p>PROBLEM TO BE SOLVED: To provide a quantitative feeder easy to clean and capable of accurately positively and stably quantitatively feeding a viscous material such as cheese. SOLUTION: This feeder is provided with suction and discharge means 1 for sucking and discharging a fed material; tubes 2, 3 formed of an elastic material and capable of conveying the fed material sucked and discharged by the suction and discharge means 1; and an opening/closing body for opening/ closing the tubes 2, 3 by pressing or the like from eth outside synchronously with the suction and discharge of the suction and discharge means 1. Actually, when the opening/closing body 4 opens the suction tube 2 and closes the discharge tube 3, a piston 11 is retreated to suck the fed material 8 into a cylinder chamber 10 of a reciprocating pump 1. When the opening/closing body 4 closes the suction tube 2 and opens the discharge tube 3, the piston 11 is advanced to discharge the fed material 8 in the cylinder chamber 10.</p> |
