Description

  The present invention relates to a solid-liquid separation device that diffuses and removes a liquid (such as oil) adhering to a pressed object (such as fried food) from the pressed object.

  A conventional solid-liquid separation device includes a rotating container having an outer wall surface through which a liquid can pass. The solid substance is accommodated in the rotating container, and the rotating container is rotated, so that the solid substance is obtained by centrifugation. The liquid was separated from the liquid (Japanese Patent Laid-Open No. 2000-237635: Patent Document 1).

  However, in this conventional solid-liquid separator, the liquid is separated from the solid matter only by centrifugation, and thus the liquid cannot be sufficiently removed from the solid matter.

For example, if the solid is a fried food and the liquid is an oil, the oil cannot be sufficiently removed from the fried food. There was a problem of bacteria breeding.
JP 2000-237635 A (FIG. 5)

  Then, the subject of this invention is providing the solid-liquid separation apparatus which can remove the liquid adhering to this solid substance from a solid substance (to-be-pressed thing) almost completely.

In order to solve the above problems, the solid-liquid separation device of the present invention comprises:
A case body having a liquid discharge hole at the bottom;
A rotating drum that is provided inside the case body and has holes on the peripheral surface and the bottom surface;
A rotation driving means for rotating the rotating drum around its axis;
It is fixed inside the rotating drum, and includes partition blades that send wind (in the axial direction and the radial direction of the rotating drum) to the rotating drum and rotate the object to be compressed.

  According to the solid-liquid separation device of the present invention, the partition blade is fixed to the inside of the rotary drum and sends the wind to the rotary drum and rotates the object to be compressed. As a result of rotation, an air flow is generated inside the rotating drum. Therefore, by accommodating the object to be compressed in the rotating drum and rotating the rotating drum, the liquid adhering to the object to be compressed from the object to be compressed can be substantially reduced by centrifugal force and air flow. It can be completely squeezed and removed.

  Moreover, when the said rotating drum is rotated, the said to-be-compressed object can be reliably hold | maintained with the said partition blade, and the idling of the to-be-compressed object can be prevented. As described above, the partition blade serves both as a blade that generates an air flow inside the rotary drum and a role as a holding plate that holds the object to be pressed and prevents idle rotation. Reduction can be achieved.

  In one embodiment, the partition blade is formed so as to gradually increase in width toward the bottom surface of the rotary drum so as to have a space around the axis of the rotary drum.

  According to the solid-liquid separation device of this embodiment, the partition blades are formed so as to gradually increase in width toward the bottom surface side of the rotating drum. Therefore, the bottom surface of the rotating drum is formed by the partition blades. The more air is discharged from the inside of the rotating drum toward the side, the air can surely flow into the bottom surface side of the rotating drum, and the liquid from the pressed object on the bottom surface of the rotating drum Can be removed more reliably.

  In addition, since there is a space around the axis of the rotating drum on the upper side of the rotating drum, the object to be squeezed can be easily put into and out of the rotating drum from the upper part of the rotating drum.

  In one embodiment, the partition blade has a hole.

  According to the solid-liquid separator of this embodiment, since the partition blade has the hole, the object to be squeezed into (intruded into) the hole of the partition blade, and from the object to be squeezed above, It will be easier to squeeze and separate the liquid.

  In one embodiment, the partition blade has a liquid guide piece extending from the shaft side of the rotating drum to the peripheral surface side of the rotating drum.

  According to the solid-liquid separation device of this embodiment, since the partition blade has the liquid guide piece, the liquid separated from the object to be squeezed is moved along the liquid guide piece with the liquid on the rotary drum. The liquid can be guided to the peripheral surface side, and the liquid can be surely excluded to the outside of the rotating drum.

  Moreover, the solid-liquid separation device of one embodiment includes a rotation speed adjusting means for adjusting the rotation speed of the rotating drum.

  According to the solid-liquid separation device of this embodiment, the rotational speed of the rotary drum can be varied by the rotational speed adjusting means. For example, according to the type or mass of the object to be squeezed, The rotation speed can be varied, and it can be applied to a wide variety of pressed objects.

  Moreover, in the solid-liquid separator of one embodiment, the pressed object is food, and the liquid attached to the pressed object is water or oil.

  According to the solid-liquid separation device of this embodiment, for example, when the object to be squeezed is a deep-fried food (such as tempura, croquette, or tonkatsu) and the liquid is oil, the apparatus of the present invention can be used. Oil can be removed from the above-mentioned fried food, it becomes greasy and becomes “crisp”, and the texture is improved. At the same time, impurities are hardly attached and bacterial growth can be suppressed. For example, when the said pressing object is vegetables and the said liquid is water, the said vegetables can be drained reliably by using the apparatus of this invention.

  According to the solid-liquid separation device of the present invention, since the partition blade is fixed to the inside of the rotating drum and sends the wind to the rotating drum and rotates the object to be compressed, the object to be compressed is rotated as described above. By accommodating the drum and rotating the rotating drum, the liquid adhering to the pressed object can be almost completely removed from the pressed object by centrifugal force and air flow.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

The power transmission unit 31 includes, for example, a worm gear or a bevel gear. A part (rotary shaft) of the power transmission unit 31 passes through the bottom surface 21 of the inner case 12 and is connected to the bottom surface 21 of the rotating drum 2.

  A rotation speed adjusting means 5 for adjusting the rotation speed of the rotary drum 2 is provided in the storage space. The rotation speed adjusting means 5 is electrically connected to the motor unit 30 and controls the motor unit 30.

  A power switch 7 and an adjustment knob 8 are provided on the front surface of the outer case 13 of the case body 1. By operating the power switch 7, the power of the rotation driving means 3 can be turned on and off. The adjustment knob 8 is electrically connected to the rotation speed adjusting means 5, and the rotation speed of the rotary drum 2 can be made variable or constant by operating the adjustment knob 8.

  A tray 6 is provided in the storage space. The tray 6 communicates with the liquid discharge hole 11 in the bottom surface 10 of the case body 1.

  The inner case 12 of the case body 1 has an opening on the upper side, and a lid 14 that opens and closes the opening of the inner case 12 is provided on the upper surface of the case body 1. The lid portion 14 has a plurality of holes 15 in a region 16 that overlaps the shaft of the rotating drum 2 with the lid portion 14 closed.

  As shown in FIGS. 4 and 5, the rotary drum 2 has an opening on the upper side, and the peripheral surface 20 and the bottom surface 21 of the rotary drum 2 have a plurality of holes 22. The rotating drum 2 is formed of, for example, a metal mesh (mesh plate) such as stainless steel. Further, a groove-like attachment portion 23 for attaching the partition blade 4 is provided inside the peripheral surface 20 and the bottom surface 21 of the rotary drum 2.

  As shown in FIGS. 3, 4, and 5, the partition blade 4 is fixed to the inside (groove-shaped mounting portion 23) of the circumferential surface 20 and the bottom surface 21 of the rotating drum 2, and the plurality of partition blades 4 are The rotating drum 2 is disposed at substantially the same central angle when viewed from the axial direction of the rotating drum 2.

  The partition blade 4 is slightly tilted and fixed so that the surface of the partition blade 4 corresponding to the downstream side (front side) in the rotation direction of the rotary drum 2 faces the bottom surface 21 of the rotary drum 2. Yes. Thus, when the rotary drum 2 rotates due to the inclination of the partition blade 4, the partition blade 4 sends wind in the axial direction and the radial direction of the rotary drum 2. That is, the rotary drum 2 and the partition blade 4 constitute an axial fan.

  The partition blade 4 gradually increases in width toward the bottom surface 21 side of the rotary drum 2 so as to have a space on the upper side of the rotary drum 2 and around the axis of the rotary drum 2. (Hereinafter referred to as “substantially triangular”). The partition blade 4 has a plurality of holes 40.

  Next, a method of using the solid-liquid separation device of the present invention and its effects will be described with reference to FIG.

  First, the lid portion 14 is opened, and the object to be squeezed 50 (shown by phantom lines in FIG. 4) is accommodated in the rotary drum 2 from the opening above the rotary drum 2. At this time, the shape of the partition blade 4 is substantially triangular and has a space around the axis of the rotary drum 2 on the upper side of the rotary drum 2, so It becomes easy to take in and out from the upper part of the rotating drum 2.

  In addition, the said to-be-compressed object 50 may exist between the said partition blades 4 and 4 adjacent, or may exist in the said space around the axis | shaft of the said rotating drum 2. FIG.

  Here, the to-be-compressed object 50 contains a liquid. Examples of the to-be-compressed object 50 include foods such as fried foods to which extra oil is attached and vegetables to which extra moisture is attached. Or a machined product to which an excess solution is attached.

  And the said cover part 14 is closed, the said rotational drive means 3 is operated by operation of the said power switch 7, and the said rotating drum 2 is rotated. Then, the partition blade 4 sends wind in the axial direction and the radial direction of the rotary drum 2 and rotates the pressed object 50 together with the rotary drum 2.

  The flow of air (air) at this time will be described. As shown by an arrow A, air enters the rotary drum 2 from the hole 15 of the lid 14 and sprays the object 50 to be compressed. Thereafter, the liquid adhering to the object 50 to be squeezed enters the tray 6 through the liquid discharge hole 11.

  For example, the tray 6 can be taken in and out of the case body 1, and the liquid collected in the tray 6 can be collected.

  Thus, the liquid attached to the pressed object 50 can be almost completely squeezed out by the centrifugal force generated by the partition blades 4 and the air flow.

  Specifically, for example, when the pressed object 50 is a deep-fried food (such as tempura, croquette, or tonkatsu) and the liquid is oil, the oil of the deep-fried food can be obtained by using the apparatus of the present invention. It can be eliminated, and it becomes greasy, making it “crisp” and improving the texture, and at the same time, it makes it difficult to attach impurities and suppresses the growth of bacteria. In addition, for example, when the pressed object 50 is a vegetable and the liquid is water, the vegetable can be drained reliably by using the apparatus of the present invention.

  Moreover, since the shape of the partition blade 4 is substantially triangular, the partition blade 4 increases the amount of air discharged from the inside of the rotary drum 2 toward the bottom surface 21 side of the rotary drum 2, Air can surely flow into the bottom surface 21 side of the rotating drum 2, and the liquid can be more reliably removed from the pressed object 50 on the bottom surface 21 of the rotating drum 2.

  In addition, since the partition blade 4 has the hole 40, the compressed object 50 enters (bits into) the hole 40 of the partition blade 4, and the liquid is extracted from the compressed object 50 and separated. It becomes easy.

  Moreover, since the rotational speed of the rotary drum 2 can be varied by the rotational speed adjusting means 5, for example, the rotational speed of the rotary drum 2 can be varied according to the type and mass of the object 50 to be squeezed, Applicable to a wide variety of pressed products.

(Second Embodiment)
6A and 6B show another embodiment of the partition blade of the present invention. The partition blade 4 has a liquid guide piece 41 extending from the shaft side of the rotary drum 2 to the peripheral surface 20 side of the rotary drum 2. The liquid guide piece 41 is provided on both sides of the partition blade 4, but may be provided only on one side.

  Thus, since the partition blade 4 has the liquid guide piece 41, the liquid separated from the object to be squeezed 50 is moved along the liquid guide piece 41 to the peripheral surface 20 side of the rotary drum 2. Thus, the liquid can be surely removed outside the rotating drum 2.

  Further, in FIG. 6A and FIG. 6B, the partition blade 4 is formed so that one end side of the liquid guide piece 41 corresponding to the shaft side of the rotating drum 2 is bent downward, as shown in FIG. 7. Moreover, the partition blade 4 may be formed such that the other end side of the liquid guide piece 41 is bent upward.

  In addition, this invention is not limited to the above-mentioned embodiment. For example, although not shown, the partition blade 4 may be fixed to a shaft portion attached to the shaft of the rotating drum 2. Moreover, although the quantity of the said partition blade 4 is not limited to 3 sheets, it is preferable that it is 2-4 sheets. Further, the flow velocity of the air inside the rotating drum 2 may be changed variously by changing the inclination angle of the partition blade 4 with respect to the bottom surface 20 of the rotating drum 2. Further, the hole 40 may not be provided in the partition blade 4.
