FIG. 5 shows an example thereof. A cylindrical body 32 having a soy milk raw material input port 31 is arranged in the horizontal direction, and a discharge port 33 is formed on the side opposite to the input port 31. A screw 34 is also arranged in the cylindrical body 32 along the horizontal direction. A drive unit 35 is connected to the screw 34. Also,

[Problems to be Solved by the Invention] Conventional soymilk squeezing machine 1a
Since it is horizontal as described above, it has the following problems.
First, since the elongated cylindrical body 32 is installed horizontally, a large installation area is required, which is contrary to space saving. Further, the soybean milk squeezed by the screw 34 mainly flows downward, and soybean milk that is a liquid does not spill on the upper screen 37. Therefore, the upper screen 37 is easily dried. Therefore, the soybean meal adhering to the screen 37 is dried and solidified to close the eyes of the screen 37, so-called clogging occurs. Therefore, it is impossible to squeeze the soymilk raw material over the entire surface of the screen 37, and there is a problem that the working efficiency is reduced. When the soybean milk squeezing machine 1a is used, the temperature of the soybean milk squeezing machine becomes considerably high and each part expands, causing uneven deformation. Further, since it is a horizontal type, an eccentric load acts on the bearing and the like. Therefore, there is a problem that the rotation of the screw is not performed smoothly, the workability is reduced, and the life of each part such as the bearing is reduced.

The present invention solves the above problems and can squeeze not only soymilk, but also bean paste used in fruits, vegetables, seaweeds and confectionery, and has a small installation area to save space. At the same time, it is possible to provide a vertical type solid-liquid separation / purification squeezing machine for food raw materials, which has good squeezing work efficiency, does not have a clogging of the screen, and can maintain the accuracy of each part at high temperature, and can improve durability. To aim.

[0006]

In order to achieve the above-mentioned object, the present invention is a squeezing machine for squeezing a food material put in a machine and separating it into a liquid squeezed separated liquid and dehydrated lees. A vertical cylindrical body having the food material charging port and the discharge port for the compressed separated liquid and the dehydrated lees which are installed along the vertical direction, and is vertically housed in the cylindrical body, and from the upper side of the charging side. A screw formed so as to reduce the volume between adjacent blades toward the lower side of the discharge side, a rotation mechanism portion of the screw, and a blade tip of the screw disposed between the vertical cylinder and the screw. A vertical type solid-liquid separation / purification squeezing machine comprising a sliding contact member to be joined and a screen on which the sliding contact member slides. Specifically, the screen is characterized in that it is gradually narrowed from the upper side to the lower side, and more specifically, when the sliding contact member is worn down, the screw is lowered,
A small gear having a length such that the sliding contact member has a mechanism capable of sliding on the screen again, and the large gear that drives the screw does not come off even when the screw is lowered. Is attached to the motor, and the drainage port of the dehydrated lees is provided with a closing lid that is pressed by a compression cylinder.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A food material introduced into a vertical cylinder from an inlet enters a gap between a vertically arranged screw and a screen and is sent from above to below by a screw lead and its own weight. . The screw reduces the volume between adjacent blades from the upper side to the lower side,
A sliding contact member that slides on the inner surface of the screen is joined to the tip of the screw blade, and the food material is compressed as it moves downward because the screen is formed in a tapered shape whose diameter is reduced downward. You. In this case, since the screen is arranged vertically, the liquid of the squeezed food does not come around and dry. Therefore, clogging does not occur and squeezing work efficiency is high. The food material is separated into a press separation liquid and a dehydrated cake by the screen, and each is sent to the next process side from an outlet. In addition, even at high temperatures, strain is concentrated in the vertical direction, and an unbalanced load is not applied to each part. Therefore, the screw is driven smoothly, and the life of the bearing and the like is prevented from being shortened. Further, a sliding contact member is joined to the tip of the blade of the screw, and this sliding contact member slides on the inner surface of the screen, so that the sliding contact member wears and a gap is generated between the inner surface of the screen and the sliding contact member. In this case, by lowering the screw, the sliding contact member can slide again on the inner surface of the screen, so that the pressure can be always maintained at the maximum and the screen is not clogged. It can be prevented.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an axial sectional view showing the entire structure of the present invention, FIG. 2 is a partial axial sectional view for explaining the squeezing action of the food material in the present invention, and FIGS. 3 and 4 are in sliding contact with the blade tip of the screw. It is sectional drawing which shows the state which a member joins.

As shown in FIG. 1, the vertical type solid-liquid separation / purification squeezing machine 1 of the present invention is roughly classified into a vertical cylinder 2 arranged along the vertical direction and a vertical cylinder 2 similarly arranged along the vertical direction. The screw 3 housed in the mold cylinder 2, the rotation mechanism portion 5 of the screw 3, and the screw 3 arranged between the vertical mold bodies 2 and the screw 3 are joined to the tips of the blades 18 of the screw 3. Sliding contact member 18a (see FIGS. 3 and 4) and the sliding contact member 1
8a is composed of a sliding screen 4 and the like.

The vertical cylinder 2 is cantilevered on a support base 6,
An input port 8 into which the food material 7 (hereinafter referred to as the raw material 7) (FIG. 2) is input and an outlet 9 from which the compressed separated liquid 12 is taken out are formed. Also, the bottom plate 10 at the lower end thereof has dehydrated lees 11 (FIG. 2).
A discharge port 13 for discharging the is formed. As shown in FIG. 1, collar members 14 and 15 are fixed above and below the vertical cylinder 2. Further, although the vertical cylinder 2 may have an integral structure,
In this embodiment, an intermediate separation type is used to improve the assemblability. The vertical cylinder 2 is reinforced and supported by the support rod 16.

The screw 3 is formed of a rotary shaft 17 of a cylindrical body and a blade 18 integrally formed on the outer periphery of the rotary shaft 17 in a screw shape. The blade 18 has a structure in which the diameter is reduced from the upper side to the lower side. Therefore, the volume between the upper adjacent blades 18 and 18 is larger than the volume between the lower blades 18 and 18. The support shaft 19 at the upper end of the screw 3 is vertically movably supported by a bracket 20 connected to the upper collar member 14. Further, the support shaft 21 at the lower end is fitted into the lower collar member 15, and is vertically supported and pivotally supported by a support tool 22 which can be fixed. The support 22 has a discharge port 1
The dehydrated lees passage 23 opened to the 3 side is penetratingly formed.

The screen 4 is composed of a screen-like member on a plate having fine pores, and a sliding contact member 18a joined to the tips of the blades 18 of the screw 3 is arranged so as to slide. In the present invention, the taper shape is such that the diameter is reduced from the upper side to the lower side. The screen 4 is installed between the collar member 14 on the upper side and the collar member 15 on the lower side. Further, the intermediate portion is reinforced and supported by the holding plate 24.

The rotation mechanism section 5 comprises a motor 25 mounted on the support base 6, a small gear 26 fixed to its rotation shaft, a large gear 27 meshing with the small gear 26, and the like. The gear 27 is connected to the support shaft 19. The small gear 26 is longer than a general small gear (pinion). This is a screw
When the sliding contact member 18a joined to the tip of the blade 18 of No. 3 is worn and a gap is formed between the sliding contact member 18a and the screen 3, the support member 22 is lowered to be fixed to the screw 3 and the screw. This is because power is transmitted even when the support shaft 19 and the large gear 27 fixed to the support shaft 19 are lowered.

The screen 4 is a metal plate having a wall thickness of about 1 to 2 mm, has innumerable fine pores (diameter: 1 to 2 μm), and is formed in a tapered cylindrical shape. The fine pores are
It can be opened by the the like. The sliding contact member 18a joined to the tip of the blade 18 of the screw-3 is the above-mentioned screen.
Slide the inner surface of the screen 4 and press the raw material 7 against the screen 4,
A resin or the like that eliminates pressure loss and prevents clogging of the screen 4, has a lower abrasion strength than the screen 4, and is capable of sliding well on the screen surface is preferable. As a joining method, they can be joined by adhering as shown in FIG. 3 or driving as shown in FIG.

The outlet 13 of the bottom plate 10 of the vertical cylinder 2 is closed by a closing lid 28. The closing lid 28 is connected to the compression cylinder 30 via a link member 29. The compression cylinder 30 is fixed to the bottom plate 10 side.

Next, the operation of the vertical type solid-liquid separation / purification squeezing machine 1 of the present invention will be described with reference to FIGS. 1 and 2. The raw material 7 is charged from the charging port 8 to the upper side of the screw 3. By driving the motor 25 of the rotation mechanism unit 5, the support shaft 19 rotates via the small gear 26 and the large gear 27, and the screw rotates. The raw material 7 is extruded downward along the lead of the blade 18 of the screw 3, and is gradually compressed in the gap formed between the screen 4 and the blade 18 and the sliding contact member 18a joined to the tip of the blade 18. The compressed raw material 7 is separated by the screen 4 into a compressed separation liquid 12 and a dehydrated lees 11. In addition, since the vertical solid-liquid separation / purification squeezing machine 1 of the present invention comprises all vertical components, the raw material 7 is easily pushed downward by its own weight. Further, the liquid generated by being compressed is also squeezed out from the entire surface of the screen 4 and becomes the squeezed separated liquid 12. The compressed separated liquid 12 descends through the gap between the outer peripheral surface of the screen 4 and the vertical cylindrical body 2, and is delivered to the next process side from the discharge port 9 formed at the lower end. On the other hand, the dehydrated lees 11 protrude from the dehydrated lees passage 23 at the lower end, overcome the pressing force of the compression cylinder 30 to press the closing lid 28, are discharged from the gap of the discharge port 13, and are continuously operated.

As described above, the vertical type solid-liquid separation / purification squeezing machine of the present invention is different from the conventional one in that it is a vertical type, so that the raw material 7 can be squeezed smoothly, and the squeezing separation liquid 12 is applied from the entire surface of the screen 4. No clogging occurs because pressure is applied. Therefore, the squeezing work efficiency can be improved. Further, it is freely displaced in the vertical direction due to thermal displacement during use, and does not generate undue strain or unbalanced load on each component. Therefore, each part can be held with high accuracy and the life can be improved.

In the above description, the structure of the screw 3 and the screen 4 is tapered, but the structure is not limited thereto. Further, although the vertical cylindrical body 2 is also a vertically separated type, the vertical cylindrical body 2 is not limited to this. Further, the rotation mechanism unit 5 is not limited to the structure of the embodiment. Further, the structure of the discharge part of the dehydrated lees 11 is not limited to the one shown in the figure, and may have an always-open type discharge port through which the dehydrated lees 11 of an appropriate size are discharged.
