Thus, when the first external gear plate 323 drives the gear shaft 3231 to pivot, the stirring disc 325 can pivot synchronously, and the solid seasoning in the first barrel 321 is stirred into the material cavity 3265 and fills the space between the two stirring sheets 32642. The drive gear set 3263 synchronously drives the metering disc 3264, and the metering disc 3264 quantitatively discharges the solid seasoning through the paddles 32642 thereon because the volumes among the paddles 32642 are consistent.

Alternatively, in order to achieve the adjustment of the seasoning discharging amount, in another embodiment, the first solid material bucket 320 is modified to design the discharging unit 326 except for including a similar first bucket body 321, a first external gear plate 323, a first stirring mechanism 324, and a stirring disc 325.

Correspondingly, the volume between the bins of the bottom cover 3212 is increased, so that the purpose of adjusting the discharge amount is realized.

Therefore, when the first external gear plate 323 drives the gear shaft 3231 to pivot, a rotation speed difference exists between the kick-out plate 325 and the fixed plate 3268, so that when the discharge hole on the fixed plate 3268 is aligned with the discharge hole at the bottom of the first charging basket, the gear shaft 3231 can drive the kick-out plate 325 to push out the solid seasoning from the discharge hole and the discharge hole, and the solid seasoning enters the bin through the discharge channel 32671.

The advantage of providing the metering cylinder 44 in cooperation with the pressure storage cylinder 43 for quantitative discharge is that the separate pressure storage cylinder 43 is large in volume, so that it is inconvenient to control the accurate outflow of consumable materials such as edible oil stored therein. While the edible oil from the pressure storage cylinder 43 is input into a metering cylinder 44 with smaller volume, the edible oil in the metering cylinder 44 is controlled to be discharged accurately.

In this manner, the feed tube 444 from the pressure feed cylinder 43 can be fed into the storage chamber of the cylinder body 441 and discharged via the discharge tube 445.

Referring to fig. 16, taking edible oil as an example, when a 4.5L pressure storage cylinder 43 and a 250mL metering cylinder 44 are used, a quantitative discharge control principle based on a constant pressure quantitative charging method of the storage cylinder 42, the pressure storage cylinder 43, the metering cylinder 44 and the discharge control valve 45 is described as follows:

setting the air pressure in the pressure storage cylinder 43 as P1, the volume of the edible oil as V1, and the liquid level of the edible oil in the pressure storage cylinder 43 as delta H;

setting the distance between the bottom of the pressure storage cylinder 43 and the bottom of the metering cylinder 44 as H;

let δv be the volume of edible oil in the pipe connecting the bottom of the pressure reservoir 43 and the bottom of the metering cylinder 44.

Since ρoil=0.9 g/cm is known ³ ＝0.9X10 ³ Kg/m ³ ，g＝9.8N/Kg，1bar＝9.8N/cm ² . At p1=4bar=39.2N/cm ² When p2=p1+ρ _{Oil (oil)} *g*(δH+H-δh)。

For the first filling of the pressure reservoir 43, δh=v1/pi R1 ² ，δh＝V2/πR2 ² The first oil charge v0=v1+v2+δv in the pressure reservoir 43, δh= (v0—δh pi R2) ² -δV)/πR1 ² 。

Since p3=p2, p3=p1+ρ _{Oil (oil)} *g*(δH+H-δh)P3＝P1+ρ _{Oil (oil)} *g*(V0-δhπR2 ² -δV)/πR1 ² +ρ _{Oil (oil)} *g*H-ρ _{Oil (oil)} *g*δh。

From this, δh= (P3-P1- ρ) _{Oil (oil)} *g*[(V0-δV)/πR1 ² +H])/(ρ _{Oil (oil)} *g*(1-πR2 ² /πR1 ² ))。
