Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a home-use rice polishing machine for polishing brown rice.

Currently known home rice polishing machines have a mechanism for adjusting the level of rice polishing, and some also have a brown rice storage mechanism and a measuring mechanism. However, all of these rice milling machines consist of mechanical mechanisms, and cannot fully automatically perform the process from setting the rice milling amount and rice milling degree to completing the rice milling.

Therefore, conventionally known rice milling machines require mechanical operations when milling rice, and are troublesome in that several various operations must be performed before rice milling is completed.

The present invention has been made in view of these problems, and it is an object of the present invention to provide a rice milling machine that can perform various operations electronically and fully automatically.

The present invention will be described below with reference to the drawings and embodiments.

FIG. 1 is a front view showing an embodiment of the present invention. In the figure, the front part of the rice milling machine is equipped with a power switch 1, a rice milling amount setting switch 2, a rice milling level setting switch 3, and a power indicator light 4. Below these mechanisms, the rice bran obtained by milling is displayed. A rice bran container 5 for storing rice bran and a rice polishing container 6 are installed. Brown rice is fed from the top of the main body by removing a lid 7 placed on the top of the main body, and the brown rice fed inside can be confirmed through a window 8 formed in the front part of the main body.

FIG. 2 is a configuration diagram showing the internal mechanism of the same embodiment, and the rice milling machine of this embodiment is provided inside and above the main body, and includes a hopper 11 for storing brown rice, a measuring container 12 for setting the amount of polished rice, A measuring plate 13 provided in the measuring container 12 for measuring brown rice supplied from the hopper 11, a measuring solenoid 16 for driving the measuring plate 13 via a connecting plate 14 and a plunger 15, and a measuring container 12. It consists of a measurement sensing micro switch 18 and a rice milling section control micro switch 19 provided at an intake port 17 for taking in weighed brown rice, and a rice milling section main body 20 for milling the brown rice taken in from the intake port 17. Furthermore, the rice polishing section main body 20 is powered by a motor 21.
A main shaft 23 whose rotation is transmitted via a belt 22
, a screw 24 that rotates as the main shaft 23 rotates, a screw-shaped rice polishing guide shaft 25 that is connected to the screw 24 and rotates as the main shaft 23 rotates, and a screen 26 for separating rice bran.
and a pressure plate 28 that pressurizes the milled rice in the screen 26 by a solenoid 27 for adjusting the rice milling degree.

The rice milling machine of the present invention having the above configuration polishes rice as follows. First, the rice polishing level setting switch 3 is set, for example, every 3 minutes, every 5 minutes,
By pressing the desired switch 3, a predetermined degree of rice polishing can be obtained, such as polishing rice every 7 minutes, every 8 minutes, and so on. That is,
Each of the switches 3 supplies a predetermined current from the control circuit C ₁ to the solenoid 27 for adjusting the rice polishing level so that a pressure suitable for each rice polishing level is applied from the pressure plate 28 to the rice polishing outlet 29. , the current is increased as the whiteness increases.

For example, rice polishing amount setting switch 2 is set to 150g (approximately 1
It can be set in 5 steps from 750 g (approximately 5 go) to ₇₅₀ g (approx. As a result, the metering solenoid 16 is energized for about 20 seconds, and the plunger 1
5, the measuring plate 13 is moved via the connecting plate 14, the brown rice in the hopper 11 is weighed in an amount of 150 g, and the amount is dropped into the brown rice intake port 17.

Therefore, by pressing any one of the rice polishing rate setting switches 3 and pressing any one of the rice polishing rate setting switches 2, the measurement sensing micro switch 18 is activated by the brown rice that has fallen into the brown rice intake port 17. Count the number of weigh-ins. At the same time, the micro switch 19 for controlling the rice milling section operates to drive the motor 21, the screw 24 pushes the brown rice forward, the rice milling guide shaft 25 moves it in the opposite direction, and the pressure plate 28
By applying pressure in the opposite direction, the rice polished within the screen 26 and the bran are separated.

After about 20 seconds, the power to the measuring solenoid 16 is stopped, the measuring plate 13 returns to its original state, and brown rice is supplied from the hopper 11 into the measuring container 12. By the way, when the brown rice is completely supplied into the rice milling unit main body 20 and rice milling is performed, the micro switch 18 returns to the normal state and drives the measuring solenoid 16 until the initially set amount of milled rice is reached. Repeat the rice polishing. however,
When the set amount of polished rice is supplied, no brown rice is supplied to the brown rice intake port 17, so the micro switch 19 returns to its original state, the rotation of the motor 21 is stopped, and the rice milling operation is stopped.

As explained above, in the rice milling machine of the present invention, firstly, the control circuit section controls the operation of the measuring section so that brown rice is weighed in unit quantities until the milled rice amount set in the milled rice amount setting section is reached. In addition, the second control circuit controls the rice milling section so that the rice is milled to a predetermined level, so just by setting the rice milling amount and milling level at the beginning, the desired amount of brown rice will be automatically produced. It has the advantage of being able to mill rice and being very easy to operate. In addition, since it is small, it is suitable for household use.
