When the food processor 1 is powered on and starts to work, the output shaft 2010 of the power device 201 in the main machine 200 drives the sun gear 30 to rotate, and the rotation speed of the output shaft 2010 of the power device 201 is set to 2400 rpm, for example, so that the rotation speed of the sun gear 30 is also 2400 rpm; the sun gear 30 rotates the first planetary gear 41, and the rotation speed of the first planetary gear 41 is as follows:

the rotation speed of the first planetary gear is equal to the rotation speed of the central gear and the gear ratio is equal to 2400 and equal to 16/48, and equal to 800 revolutions per minute

Accordingly, the first planetary gear 41 rotates the plunger holder 50 and the stirring device 400, for example, a stirring rod, and the rotation speed of the stirring device 400 is also 800 rpm. Do benefit to the rotational speed of sending out on the existing market and be 600 ~ 1200 rpm usually between, consequently, the utility model provides a rotation rotational speed of 800 rpm of agitating unit 400 can satisfy the requirement of sending out the rotation rotational speed on the market.

The rotation of the first planetary gear 41 can simultaneously rotate the second planetary gear 42 in the gear reduction mechanism, and the rotation speed of the second planetary gear 42 is as follows:

the rotation speed of the second planetary gear is equal to the rotation speed of the first planetary gear multiplied by the gear ratio 800 multiplied by 24/48 is equal to 400 revolutions per minute

The rotation of the second planetary gear 42 can simultaneously rotate the third planetary gear 43, and the rotation speed of the third planetary gear 43 is as follows:

the rotation speed of the third planetary gear is 400 x 16/20, 320 rpm

Since the third planetary gears 43 are engaged with the fixed outer ring gear 10 and fixed to the rotating frame 20, the rotation of the third planetary gears 43 rotates the rotating frame 20, and the rotation speed of the rotating frame 20 is as follows:

the rotation speed of the rotating frame is equal to the rotation speed of the third planetary gear multiplied by the gear ratio of 320 multiplied by 20/160 is equal to 40 revolutions per minute

The rotation speed of the rotating frame 20 is significantly reduced by the gear reduction mechanism.

Since the first planetary gear 41 is located on the turret 20, the first planetary gear 41 revolves around the axis of the sun gear 30 along with the turret 20, and the rotation speed of the turret 20 is the revolution speed of the first planetary gear 41. The first planetary gears 41 simultaneously drive the plunger holder 50 and the stirring device 400 to revolve around the axis of the sun gear 30 along with the rotating frame 20. Therefore, the revolution speed of the stirring device 400 is also 40 rpm, which is similar to the speed of the hand-held food processor 1 for manually beating.
