Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a juicer that allows the amount of pulp or fiber in juice to be freely controlled according to the preference of the person making the juice.

Generally, there are two factors that determine the amount and size of pulp and fiber contained in juice.

First of all, the size of the pulp and fibers when the material input from the material input port is cut by a cutter and turned into a paste.

The second is the shape and size of the pores in a portion of the filter.

In fact, tomatoes with naturally fine fibers and pulp have a high amount of pulp and fiber in the separated juice.
The juice is thick and highly viscous, but for vegetables with long fibers like carrots, the separated juice is smooth and low in viscosity with little fiber.

If you want to increase the amount of fiber and pulp in the juice, you can make the cutter blade finer and cut the fibers into smaller pieces, and if you increase the mesh size of part of the filter, you can relatively increase the amount of fiber and pulp in the juice. becomes large and becomes a highly viscous juice.

However, in order to change the shape of the cutter or part of the filter, the separation basket must be replaced, and the only option is to prepare several separation baskets and change them according to your preference, which is not very practical. Ta.

The present invention focuses on the magnitude of centrifugal force during separation as a means of controlling the amount of fibers and pulp in juice, and will be described below with reference to the accompanying drawings.

In the figure, 1 has a motor, 2 a separation cage driven by the motor 1, and a filter portion 3 having an inverted conical shape.

4 is provided at the inner bottom of the separation basket 2. 5 is a container having a waste receiving part 6, a juice receiving part 7 and a juice outlet 8; 9 is a lid installed on the container 5, which integrally forms a material input port 10 facing the cutter 4; .

Reference numeral 11 designates a main body case which houses the motor 1 and places it on top of the container 5, and 12 designates a speed adjustment device for adjusting the rotation speed of the motor 1.

In the above-mentioned juicer, the material is separated into waste and liquid by the rotation of the separation wheel 2, as in the case of ordinary juicers.

As shown in FIG. 2, fibers or pulp adhere to the holes 13 of the filter part 3, spanning the holes or being clogged, blocking the holes and preventing the fibers coming later from passing through. There is a risk of interfering.

In this case, it was found that as the rotational speed of the motor was increased, the centrifugal force increased and the fibers attached to the holes 13 had the effect of pulling the pulp away.

Transfer the squeezed juice to a graduated cylinder as shown in Figure 3A.
If you put it in a transparent container and leave it for several hours to separate the liquid part from the pulp and fiber parts, and examine the volume ratio, you will get something like the graph in Figure 3B.

7000-10000 r, p as you can see from the graph
The pulp/juice ratio increases parabolically from around , m.

In addition, the hole shape of a part of the filter in this case is rectangular as shown in Fig. 3C, with a length of 0.12 mm x 2.3 mm and a vertical pitch of 0.
．． 6 my)% Directional pitch 2.8 mvt Open area ratio 27.
It is 4%.

As can be seen from this experiment, the rotation speed and the pulp/juice ratio begin to show a strong correlation when the rotation speed is exceeded.

FIG. 3B also shows a case where the pore shape of a part of the filter is changed.

In this way, there is also a correlation between the pore shape, rotation speed, and pulp/juice ratio.

As is clear from Figure 3B above, 7000 to 80
At rotation speeds below 00 r, p, m, there is almost no correlation between the rotation speed and the pulp and juice ratio.
At higher rotation speeds, it depends on the shape of the part of the filter,
It can be seen that the pulp and juice ratio reaches 100%.

Therefore, by utilizing such a relationship, it is possible to obtain a juicer that can adjust the pulp-juice ratio to a desired value by electrically or mechanically switching the rotational speed in multiple stages or steplessly.

Therefore, the juicer of the present invention has a power consumption of 7,000 to 8,000 r.
, p, and m are the minimum speeds, and above these, the speed adjustment device 12 can freely adjust the rotation speed.

However, in reality, the maximum rotation speed is 2000 Or
, p, and m, it has been confirmed through experiments that it cannot be put to practical use, so the number of revolutions cannot be increased indefinitely.

Therefore, 7000-200 ON) f', p-m
By steplessly adjusting the rotational speed within the range of , it is possible to freely create juice with the desired concentration at a specific rotational speed position.

In the embodiment shown in FIG. 4, the angle of a portion of the filter at the separation corner is set in two stages, with a lower inclination angle α and an upper inclination angle β.

In this separation cage, at low speeds, the holes 13 in the first stage at the angle α are blocked by fibers, etc., and the role of the filter part at the angle β, which is larger, mainly plays the role of the filter part.

In this case, the proportion of pulp in the juice is lower than in conventional separation.

Next, when the centrifugal force is increased, the clogging at the angle of inclination α becomes less and the filter functions as part of the filter.

In this case, it is more effective to make the holes in the α part larger than the holes in the β part.

In FIG. 5, a cylindrical part 15 is provided at the lower part of the filter part 3,
A plurality of holes 2 are provided in the other side wall.

In this case as well, the same effects as in the above embodiment can be expected.

As described above, the present invention adjusts the amount of fiber and pulp in juice by adjusting the magnitude of centrifugal force during separation, and it is possible to obtain juice with a concentration according to preference. The effect is extremely large.
