Rotary Quantitative valves are side peripheral surface inlet port of the valve chamber of the casing, is connected to the discharge port of the separately provided screw conveyor, food by the screw conveyor at a position where one end of the cylinder chamber communicates with the inlet port When pressure-fed, the top located at the inlet port moves horizontally through the cylinder chamber to the opposite side while exhausting the air behind the top from the casing through the air discharge hole, and food is fed into the cylinder chamber. When the rotary valve is rotated 90 degrees and one end of the cylinder chamber communicates with the upper push-out port and the other end communicates with the lower outlet port, the discharge piston is lowered and the discharge stroke is performed. The top is pushed down and the food in the cylinder chamber is sent to the loosening means. Next, when the rotary valve rotates backward by 90 degrees and food is pumped by the screw conveyor at a position where one end of the cylinder chamber communicates with the inlet port, the piece positioned at the inlet port moves to the opposite side. Quantification is performed by repeating this operation.

As the blades of the rotary blade, which has a plurality of rectangular parallelepiped protruding piece that protrudes radially with different in elevation angle at which及beauty upright position from the rotation axis is preferred. The number of rotations of the rotating blades depends on the type of food to be loosened and the shape of the blades, but when rotating at 3000 to 4000 rpm, preferably 3200 to 3800 rpm, the food becomes soft from a state where the food has hardened in a short time. It can be changed to the state.

It is preferable to dispose container transport means having a container transport conveyor and a conveyor intermittent drive mechanism below the loosening means. A certain amount of food is discharged from the quantitative means, and the food loosened by the loosening means in the middle of dropping is quantitatively filled into the container on the container transporting conveyor immediately below the loosening means. If a shutter is provided, it is possible to prevent food from falling during transport of the container. The conveying pitch of the vessel, 4-10 seconds, have preferably preferred in that be 4-6 seconds increase productivity.

  Furthermore, as a rotary valve, a plurality of, for example, a rotary metering valve having a cylindrical rotary (columnar) valve having five cylinder chambers (filling passages) in the axial direction of the rotary valve is used. It is also possible to increase the productivity by configuring the quantifying means, the loosening means, and the container conveying means in multiple rows.

  The quantitative soft filling method of the present invention is a method using the quantitative soft filling device of the present invention, and the volume compressed by the quantitative means is 1.5 to 4000 by setting the rotation speed of the rotating blades to 3000 to 4000 rpm.
