[0002] Food additives refer to chemical synthetic or natural substances added to food to improve food quality, color, aroma, and taste, as well as for preservation and processing needs. During the production of food additives, a quantitative feeding device is required for quantitative feeding of raw materials.

[0003] For some quantitative feeding devices for food additive production on the current market, on the one hand, when the quantitative cylinder outputs raw materials, raw materials are likely to adhere and remain on the cylinder wall, and the adhered residual raw materials will cause a reduction in the actual output, resulting in errors and affecting the quality of food additives.

The motor 13 drives the rotating shaft 8 to rotate forward, and at the same time, the first solenoid valve 19 is powered off and closed, and the second solenoid valve 20 is powered on and opened. The raw materials in the metering cylinder 3 are discharged outward through the discharge pipe 18 and the third hose 22, and then the above steps are repeated. The raw materials in the metering cylinder 3 can be automatically introduced and exported, which is convenient for continuous production.

[0050] Specifically, the quantitative adjustment of each metering cylinder 3 is carried out through the metering mechanism 5, and the upper execution component 14 is adjusted to make the control rod 162 of the shaft rotation control mechanism 16 above the surplus mechanism 6 pop out and contact the side surface of the top end of the metal seesaw 24, so that the metal seesaw 24 presses the first switch 25 and the second switch 26, and contacts and adsorbs and fixes with the first magnet 42. The second solenoid valve 20 is energized and opened, and then the motor 13 is started to drive the rotating shaft 8 to rotate forward. The raw materials in the metering cylinder 3 are exported outward through the discharge pipe 18 and the third hose 22. As the rotating shaft 8 rotates, the first wire wheel 9 winds the first pulling wire 11, and the surplus mechanism 6 is pulled to move through the first pulling wire 11. The first mechanism spring 406 is compressed, and the threaded rod 403 drives the cleaning plate 402 to move out of the hidden groove in cooperation with the threaded hole of the metering cylinder 3 and rotates. As the threaded rod 403 and the cleaning plate 402 move, the auxiliary plate 404 contacts the push plate 401, causing the push plate 401 to move. As the rotating shaft 8 rotates, the second wire wheel 10 winds the second pulling wire 12, and the pressing plate 701 is pulled through the second pulling wire 12 to squeeze the negative pressure bladder 703, so that the fluid in the negative pressure bladder 703 enters the flow cavity 4031 through the first hose 704 and the connecting pipe 602 and is sprayed on the inner wall of the metering cylinder 3 through the diversion holes 4021 of the cleaning plate 402 to clean the residual raw materials. It can be switched between air introduction and water flow introduction as needed by rotating the stud 36 to move the baffle 37. When the baffle 37 covers the connecting pipe 34, the inflow hole 351 is communicated with the diversion pipe 39, which is the air introduction state. The device can blow and clean the inner wall of the metering cylinder 3 with air flow. When the baffle 37 covers the inflow hole 351, the connecting pipe 34 is communicated with the diversion pipe 39, which is the water flow introduction state. During the process of replacing the raw materials of a new batch, the device can spray and clean the inner wall of the metering cylinder 3 with water flow to remove the residual raw materials of the old batch, and then switch to the air introduction state again to air-dry the inner wall of the metering cylinder 3. As the motor 13 drives the rotating shaft 8 to rotate forward, after the quantitative cleaning mechanism 4 in each metering cylinder 3 completes the cleaning work, the push plate 401 contacts the execution column 153 of the lower execution component 15, the third compression spring 154 is compressed, and the third U-shaped plate 155 moves and inserts into the shaft rotation control mechanism 16 below the metering cylinder 3, contacts the first U-shaped plate 164, and squeezes the fourth mechanism spring 165. Then the control rod 162 will pop out under the action of the third mechanism spring 163 and contact the side surface of the bottom end of the metal seesaw 24. While the metal seesaw 24 rotates, the bottom end of the metal seesaw 24 presses the third switch 27 and the fourth switch 28 and contacts and adsorbs and fixes with the second magnet 43. Then the motor 13 drives the rotating shaft 8 to rotate in reverse, and at the same time the first solenoid valve 19 is energized and opened, and the second solenoid valve 20 is de-energized and closed, and the raw materials in the feed bin 30 enter the metering cylinder 3.
