Description

The present invention relates to a squeezing apparatus and method for squeezing citrus fruits such as citrus fruits such as tangerines and oranges, yuzu, sudachi, hassaku, and grapefruit, and squeezing roughly halved fruits.

Conventionally, various methods of squeezing and squeezing fruits such as citrus fruits have been carried out. Typical examples include an in-line system and a chopper pulper system. In the in-line method, the fruit is washed, processed to be finely ground together with the skin, and then centrifuged to remove solids. Therefore, although it has a smooth taste, there is a problem that the skin is squeezed with the skin, so the oil content of the skin is mixed to some extent, and the taste is mixed.

On the other hand, the chopper-pulper method involves removing the skin of the fruit and then squeezing the fruit together with the thin skin. For this reason, the oil content of the skin is not mixed in, so although it is mild and full-bodied, in order to peel many fruits cleanly, it is necessary to apply steam to soften it and then peel it by hand.

In the chopper-pulper method, the fruit juice is crushed through a puree called a pulper finisher, so it contains a large amount of fiber (pulper) in the thin skin. This point is the same for the in-line method. Among the fibers (pulper), especially when the funnel membrane is crushed, bitterness and lye are produced. Then, it is necessary to add an enzyme that decomposes the pectin and fiber of the funnel membrane and the above-mentioned vascular bundle, or to neutralize it after adding acid. I can't get the taste of just.

Therefore, Patent Literature 1 discloses a typical conventional technique for collecting only fruit juice without peeling the outer skin and crushing the skin and seeds. According to the prior art, the fruit is split in half, and the half-split surface is pressed against a substantially conical juicing part, which is larger than the expected flesh part and looks like an upside down bowl. be. Patent Literature 1 describes a typical domestic fruit juice squeezer made of stainless steel, in which a flange for storing fruit juice and a rising wall around the flange are formed at the edge of the squeezing part.

Registered Utility Model No. 3034332

According to the above-described prior art, a sufficient juicing effect can be obtained for a wide variety of citrus fruits by making the juicing portion larger than the assumed pulp portion. However, since the fruit is pressed by hand, there are parts where force is applied and parts where it is not applied depending on the part to be pressed. It will be crushed and the same problem as described above will occur.

SUMMARY OF THE INVENTION An object of the present invention is to provide a squeezing apparatus and method capable of obtaining fruit juice free from bitterness, lye and oil.

The juice squeezing device of the present invention is formed in a bowl shape and includes a pair of inner and outer molds that can be fitted to each other, and driving means for driving the pair of inner and outer molds toward and away from each other. The half-section side of the fruit is brought into contact with the inner mold and the outer surface side of the fruit is brought into contact with the outer mold, and the fruit is squeezed between the pair of molds to squeeze the juice. .

In addition, the juice squeezing method of the present invention uses a pair of cup-shaped molds that can be fitted to each other. It is characterized by squeezing the fruit by bringing it into contact with each of the outer molds and pressing the fruit between the pair of molds.

According to the above configuration, a fruit such as a citrus fruit is roughly split in half, and from the split surface, a bowl shape, specifically a hemisphere, a dome shape, or the like is included, from the waist to the body and the mouth edge. When squeezing juice by pressing against a mold that rises in a gentle curve, the half-split surface of the mold is pressed against the inner mold. Also provided is a drive means to drive the pair of molds towards/away from each other to allow juicing and loading of fresh fruit and removal of residue.

Therefore, in the inner and outer molds, the fruit that is roughly split in half is crushed, and only the pulp, specifically the gizzard portion, is crushed, and the mesocarp, vascular bundles, and the tunic membrane portion, which is particularly effective, are crushed, as well as the exocarp. The juice can be squeezed without crushing as much as possible. As a result, it is possible to obtain fruit juice free from bitterness, lye, and oil due to those parts. In addition, in order to obtain fruit juice without such bitterness, as in the past, for example, an enzyme that decomposes the pectin and fiber of the vascular bundle and the funnel membrane is added, an acid is added, No need to neutralize afterwards.

Furthermore, in the juice squeezing apparatus of the present invention, the pair of molds has smooth surfaces facing each other.

According to the above configuration, in the conventional fruit juice squeezer, ribs are set up on the projecting portion against which the half-split fruit is pressed, and the fruit is squeezed by twisting. Instead, not only the inner mold but also the outer mold have their facing surfaces smooth.

Therefore, only the fruit juice component can be obtained without stripping off the vascular bundles and the funnel membrane with the ribs or crushing the oil vesicles in the epicarp. In addition, the residue can be used as feed or the like, and since the oil sacs remain, the essential oil can be extracted from the residue to increase the utility value of the residue.

Further, in the juice squeezing device of the present invention, the pair of molds are arranged such that the outer mold is arranged upward and the inner mold is arranged downward, and the top of the outer mold is formed with a hole communicating with the outside air. and

According to the above configuration, by setting the outer mold upward and the inner mold downward, the squeezed fruit juice drips down along the inside of the half-split fruit, so that it does not come into contact with the outer surface of the fruit and is hygienic. can be collected. In addition, since the opposing surfaces of the upper and lower molds are smooth, a hole is provided in the top of the upper outer mold so that when the molds are separated, air can pass through and the remaining residue can be removed from the lower inner mold. It will adhere to the mold, making it easier to collect the residue. In addition, the trouble of cleaning the upper outer mold, which is difficult to clean, can be saved.

Furthermore, in the juice squeezing device of the present invention, the top of the inner mold has a tapered sharp portion that pierces the center of the half-section side of the roughly halved fruit and fits into the hole of the outer mold. It is characterized by

According to the above configuration, the set fruit is prevented from slipping down on the surface of the inner mold by providing the sharp portion that pierces the center of the half-section side of the roughly half-split fruit on the top of the inner mold. can do. In addition, when the molds are separated from each other, the sharp portion catches the residue and makes it easier to peel off from the outer mold. No problems arise.

Further, in the juice squeezing device of the present invention, the sharp portion is replaceable from the inner mold.

According to the above configuration, the sharp portion is worn by hitting, bending, and rubbing against the vicinity of the entrance of the hole with the pericarp or the like sandwiched therebetween or directly. Therefore, by forming an external screw on the base end side of the sharpened part and providing a nut on the back side of the top part of the inner mold, the sharpened part can be replaced, thereby reducing the maintenance cost of the squeezing device. can be done.

Furthermore, the juice squeezing apparatus of the present invention includes an endless annular conveyor on which the inner mold is mounted, a frame straddling the conveyor and supporting the driving means and the outer mold, and a feeding means for driving the conveyor. It is characterized by

According to the above configuration, the inner molds are sequentially conveyed by the conveyer by the feeding means, and the outer molds are lowered and squeezed by the driving means mounted on the frame installed at a predetermined position on the conveyor. is an endless ring and rotates the inner die sequentially. In this way, juice can be continuously and efficiently extracted from the fruit.

Further, in the juice squeezing apparatus of the present invention, a hooking member for hooking the fruit is provided on the downstream side of the frame, on the channel of the inner mold, at a position on one side offset from the center of the flowing inner mold. It is further provided.

According to the above configuration, the fruit (residue) adsorbed to the inner mold is hooked and peeled off at a position close to the flowing inner mold on the frame, that is, on the flow path downstream of the squeezing position. Provide members. The hooking member is composed of a claw (pin) or a blade, and it should be noted that it is provided only at one side position offset from the center of the inner mold.

Therefore, the fruit (residue) adsorbed to the inner mold can be peeled off from the inner mold by rotating around the sharpened portion, and can be peeled off efficiently and reliably.

Furthermore, in the juice squeezing apparatus of the present invention, the hooking member is provided downstream of a position where the endless annular conveyor starts folding back.

According to the above configuration, the hooking member rotates the fruit (residue) adsorbed to the inner mold and separates it from the inner mold. On the other hand, by providing it on the downstream side of the position where the folding is started, the fruit (residue) that has risen can be removed from the inner mold and dropped. In this way, the fruits (residues) can be removed more efficiently and reliably.

Further, in the juice squeezing device of the present invention, a baffle plate is provided downstream of the hooking member, the baffle plate being cut out in a shape with a predetermined interval from the outline of the vertical cross section of the inner mold. do.

According to the above configuration, although the hooking member rotates the fruit (residue) adhered to the inner mold and separates it from the inner mold, there is a possibility that the hooking member may not completely remove the fruit from the inner mold. Therefore, by providing a baffle plate cut out close to the outline of the inner mold on the downstream side of the hooking member, the fruit (residue) can be removed more reliably in two stages.

Furthermore, in the juice squeezing device of the present invention, the baffle plate is provided between the middle point of the turn-up of the endless annular conveyor and the end point of the turn-up, and is located on the opposite side of the portion facing the inner die. It is characterized by being elongated in a plate shape.

According to the above configuration, by providing the baffle plate between the middle point of the turning of the conveyor and the end point of the turning, the fruit (residue) that has been peeled off is surely dropped in two stages with the hooking member. be able to. Furthermore, by extending the baffle plate in the form of a plate on the side opposite to the inner mold, it can function as a shooter (guide member) for the fallen fruits (residues).

Preferably, the inner diameter of the outer mold is 103 mm, the outer diameter of the inner mold is 100 mm, and the vicinity of the top of the inner mold is in close contact with the inner peripheral surface of the outer mold. By doing so, for example, the residue of a large 3L size mandarin orange accumulates more in the gap below the top of the inner mold, and the small sudachi is evenly pressed in the vicinity of the top of the inner mold. In this way, one type can squeeze a wide range of fruits, from large to small.

Furthermore, in the juice squeezing apparatus of the present invention, the force for pressing the outer mold against the inner mold is 50 to 70 kgf, and the pressing time is 4 to 6.5 seconds.

According to the above configuration, for example, an L-size ripe mandarin orange is soft, and in such a case, the pressing force is small at about 50 kgf, and the juice can be sufficiently squeezed in a short time of about 4 seconds. On the other hand, relatively hard and large grapefruits, sweet berries, and the like require a large pressing force of about 70 kgf and a long time of about 6.5 seconds. In this way, the fruit juice free from bitterness, lye and oil can be efficiently obtained.

As described above, the juice squeezing apparatus and method of the present invention divides a fruit such as a citrus fruit into halves, presses the halves against a bowl-shaped mold from the halves, and extracts the juice. The mold to be pressed is the inner mold, and in the present invention, an outer mold that can be fitted over the inner mold is also provided. Allows for juicing and loading of fresh fruit and removal of residue.

Therefore, it is possible to squeeze only the flesh of the fruit, which is roughly split in half, in the inner and outer mold, and squeeze the mesocarp, vascular bundles, and especially the tunica part as much as possible, as well as the exocarp. . As a result, it is possible to obtain fruit juice free from bitterness, lye, and oil due to those parts.

Then, the squeezing part 2 brings the half-split fruit 8 into contact with the inner mold 21 on the half cross-section side and the outer mold 22 on the outer surface side, respectively, and presses between the pair of molds 21 and 22. The juice is squeezed by pinching and pressing the fruit 8 with. In this embodiment, the pair of molds 22 and 21 are arranged vertically, the inner mold 21 is fixed at a predetermined position, and the outer mold 22 is vertically displaced by the driving means 23 .

In this embodiment, a plurality of sets of molds 21 and 22 are provided. Specifically, as one example, a total of 12 sets of 4 columns x 3 rows are provided, and 12 fruits 8 are squeezed at one time. . Therefore, the 12 outer molds 22 are attached to a common plate 25 and moved up and down collectively by the drive means 23 . In this embodiment, the driving means 23 is a hydraulic cylinder, and the plate 25 has a bracket 251 provided on its edge, which is positioned between the top plate 242 of the frame 24 and the upper beam 311 of the frame 31 of the conveying device 3 . It is guided in the vertical direction by a guide shaft 26 erected on the . A stopper (not shown) is provided below at least some of the guide shafts 26 to prevent the plate 25 and the upper die 22 mounted thereon from falling too far and colliding with the lower die 21 . The driving means 23 for the hydraulic cylinder is mounted on the top plate 242 of the frame 24 . The driving means 23 of the hydraulic cylinder is moved forward and backward by hydraulic pressure from a hydraulic pump and a valve (not shown) to vertically displace the outer die 22 from the plate 25 . Said hydraulic pumps and valves are controlled by a control panel 7 .

FIG. 2 is a perspective view showing the conveying device 3 in detail. The squeezing part 2 is provided at a predetermined position of the conveying device 3 , and the gate-shaped frame 24 is provided so as to straddle the conveying device 3 . The conveying device 3 is configured based on a chain conveyor. Specifically, a pair of endless annular chains 33, 34 laid on both sides in the conveying direction, a pair of rod-shaped bases 35 connecting the chains 33, 34 on both sides, and the chains 33, 34 A pair of driving and driven sprockets 36 that are held by a tension of , and are rotationally driven, a driving mechanism (not shown) that rotates the driving sprockets, and a frame 31 that guides and holds the pair of chains 33 and 34. configured with.

The drive mechanism is configured by appropriately including a motor, gears, chains, belts, and the like. The sprocket 36 and the driving mechanism constitute feeding means. The driving and driven sprockets 36 are configured to have diameters that correspond to the feeding amount of three of the pair of bases 35 for one rotation. That is, when the sprocket rotates once, a total of 12 fruits 8 of 4 columns×3 rows are set. One side of the sprocket is provided with a means for detecting one rotation of the sprocket, and the drive motor is controlled by the control panel 7 in response to the detection result. For example, the sprocket is provided with a magnetic projection at one point in the circumferential direction, and one rotation can be detected by detecting it with a magnetic sensor provided at a fixed position. By realizing the conveying device 3 by a conveyor in this manner, the juice from the fruit 8 can be continuously and efficiently extracted.

In this embodiment, the base 35 is composed of a pair of rod-shaped bodies so that the fruit juice can easily flow down, but it may be composed of a plate or a mesh plate. The molds 21 for 1 row and 4 columns are mounted on the pair of rod-shaped bodies of the base 35 by welding 214 or the like. The attachment of the mold 21 to the base 35 is directly performed by welding 214 in FIG. In this embodiment, since the fruit 8 is manually set by an operator, the conveying device 3 is longer in the front (upstream) side than the juice squeezing section 2 and shorter in the back (downstream) side.

FIG. 3 is a sectional view of the molds 21 and 22 fitted together, and FIG. 4 is an exploded perspective view of the mold 21. As shown in FIG. The mold 21 has a body 211 made of a stainless steel butt-weld type pipe joint cap, and a nut 212 is joined by welding 215 or the like to the inner side of the body 211 . A sharp portion 213 is screwed to 212 . A so-called stainless hot material is used for the main body 211, and the material is SUS304W, 316LW, 316W, or the like. The sharpened portion 213 includes a conical portion 2131 that pierces and holds the fruit 8, and a screw portion 2132 that is carved from the base end thereof and screwed into the nut 212 through the hole 2111. created by, etc.

FIG. 5 is an exploded perspective view of the mold 22. FIG. A nut 222 is welded 225 or the like to the outer surface near a hole 2211 formed in the top of a body 221, which also consists of a stainless steel butt weld fitting cap made of the same material as body 211 of mold 21. A cylindrical body 223 having a thread formed on its outer peripheral surface is screwed to the nut 222 and fixed by welding. The cylindrical body 223 is inserted through a hole formed in the plate 25 and fixed with a nut.

On the other hand, on the back (downstream) side of the conveying device 3, a residue removing device 5 is provided from a position where the conveyor starts to turn back. FIG. 6 is a perspective view of the leaving device 5. As shown in FIG. The residue-removing device 5 removes the residue of the fruit 8 adhered to the mold 21 in two stages while the mold 21 is conveyed by the conveying device 3. It is composed of a member 51 and a baffle plate 52 on the second stage (downstream side). As will be described later, the fruit 8 (residue) adsorbed to the inner mold 21 is peeled off and dropped by the hooking member 51 , and the fruit 8 (residue) dropped by the hooking member 51 is further transferred to the following baffle plate 52 . and let it drop. The fallen fruits 8 (residues) are collected in a basket 91 or the like. When a plurality of juicing apparatuses 1 are installed side by side, the fruits 8 (residues) are collected at one place by a conveyor or a shooter drawn through the vicinity of the drop position of the fruits 8 (residues).

The fruit juice squeezed out by the squeezing part 2 drips from the inner mold 21 through the gap of the base 35, has an area wider than at least the squeezing part 2, and is interposed between the reciprocating base 35 (conveyor). It is received by the fruit juice receptacle 4. The fruit juice receptacle 4 is composed of an inclined plate 41 and a gutter 42 formed at the bottom of the inclined plate 41, and the collected fruit juice passes through a filter net 61 that removes coarse garbage and fruit 8 (residue). , is stored in the tank 62 . The filter screen 61 and the tank 62 constitute the reservoir 6 . When a plurality of juice squeezing apparatuses 1 are installed side by side, the gutter 42 is sequentially drawn through the plurality of apparatuses and collected in one tank 62 .

The juice collected in the tank 62 is filtered after the tank 62 is replaced or pumped out when a predetermined amount is accumulated. The filtered juice is bottled or stored frozen. Prior to final shipment, the juice is pasteurized in the bottled state. Although not shown, the fruit 8 brought in from farmers, agricultural cooperatives, etc., is washed with a brush or running water, sorted by size and damage, and then divided into two by a slicing machine. is brought in. In this embodiment, the setting of the fruit 8 to the inner mold 21 is performed by the operator 10, but such washing, sorting, dividing, and setting may be performed collectively by a machine.

In the squeezing device 1 configured as described above, first of all, it should be noted that in the squeezing unit 2 and the squeezing method of the present embodiment, the fruit 8 such as citrus is roughly split in half, and from the split surface , when squeezing juice by pressing against a bowl-shaped mold 21 as in Patent Document 1, as shown in FIG. 22 is also provided. Then, the half-cut fruit 8 is brought into contact with the inner mold 21 at its half cross-section side and with the outer mold 22 at its outer surface side, and the pair of molds 21 and 22 are brought into contact with each other by the driving means 23 . drive towards/away from allows squeezing and loading of fresh fruit 8 and removal of residue.

With this configuration, the inner and outer molds 21 and 22 crush the substantially half-split fruit 8, specifically, crushing only the pulp, specifically the sand sac portion, and crushing not only the exocarp, but also the mesocarp, vascular bundles, and especially the effect. It is possible to squeeze the large funnel membrane part without crushing it as much as possible. As a result, it is possible to obtain fruit juice free from bitterness, lye, and oil due to those parts. In addition, in order to obtain fruit juice without such bitterness, as in the past, for example, an enzyme that decomposes the pectin and fiber of the vascular bundle and the funnel membrane is added, an acid is added, No need to neutralize afterwards.

It should also be noted that the pair of molds 21 and 22 have smooth surfaces facing each other. Here, in the fruit juice squeezer of Patent Document 1, grooves are formed in the protruded portion against which the fruit is pressed to pass the fruit juice, but in many fruit juice squeezers, ribs are formed in the protruded portion. Standing up, twisting and squeezing the fruit. On the other hand, in the squeezing part 2 of the present embodiment, not only the inner mold 21 but also the newly provided outer mold 22 are formed with smooth facing surfaces.

With such a configuration, only the fruit juice component can be obtained without stripping off the vascular bundles and the funnel membrane with the ribs or crushing the oil sacs in the epicarp. In addition, the residue is not only pulverized and used as feed, but also sliced and processed into marmalade or peel because the epicarp to the endocarp remain clean. Essential oils can be extracted from it to enhance the utility value of the residue.

Specifically, since the opposing surfaces of the molds 21 and 22 are smooth, the driving means 23 presses the outer mold 22 against the inner mold 21 with a force of 50 to 70 kgf and a pressing time of 4 to 6.5 seconds. be. This is because the pressure of the hydraulic cylinder is 0.4 to 0.5 MPa, and if 0.4 MPa, the shaft diameter is 6 cm, so the force pushing down the plate 25 is 1152.67 kgf, which is 12 When divided by , the output is 96 kgf, which is 50 to 70 kgf given that the actual output of general hydraulic equipment is about 50 to 70%.

More specifically, for example, an L-size ripe mandarin orange is soft, and in such a case, the pressing force is small, about 50 kgf, and the juice can be sufficiently squeezed even with a short time of about 4 seconds. On the other hand, relatively hard and large grapefruits, sweet berries, and the like require a large pressing force of about 70 kgf and a long time of about 6.5 seconds. In this way, the fruit juice free from bitterness, lye and oil can be efficiently obtained.

In addition, in the juice squeezing device 1 of the present embodiment, the bowl shape of the main bodies 211 and 221 of the molds 21 and 22 is a hemisphere or a dome shape (including a shape in which an ellipse like a rugby ball is roughly halved). ), etc., and it is a shape that rises in a gentle curve from the waist to the body and the lip. For example, in this embodiment, the inner diameter of the outer mold 22 is 103 mm, and the outer diameter of the inner mold 21 is 100 mm. Furthermore, the main bodies 211 and 221 of the molds 21 and 22 have a shape that is slightly flattened at the top rather than a hemisphere. Specifically, each body 211, 221 obtains such shape by being comprised of said stainless steel butt weld fitting cap. In addition, the main body 211 of the lower mold 21 is not limited to the hemispherical shape as described above, and may be a full sphere.

Therefore, the point that the inner mold 21 is larger than many fruits 8 is the same as in Patent Document 1, but for example, a large amount of residue of a large 3L size mandarin orange accumulates in the gap below the top of the inner mold 21, In the case of small sudachi, the entire sudachi is evenly pressed near the top of the inner die 21 . In this way, one type 21, 22 can squeeze a wide variety of fruits, from large fruits to small fruits.

Furthermore, it should be noted that in the juice squeezing unit 2 of this embodiment, the pair of molds 21 and 22 are arranged such that the outer mold 22 is arranged above and the inner mold 21 is arranged below, and the top of the outer mold 22 is , a hole 2211 communicating with the outside air is formed, and the hole 2211 communicates with the outside air through the cylindrical body 223 .

By setting the outer mold 22 upward and the inner mold 21 downward in this way, the squeezed fruit juice drips along the inside of the half-split fruit 8, so that it does not come into contact with the outer surface of the fruit 8 and is hygienic. can be collected. As described above, the pair of upper and lower molds 22 and 21 have smooth surfaces facing each other. When the mold 22 separates, air passes through and the remaining residue is adsorbed to the inner mold 21 below, making it easier for the residue removing device 5 to collect the residue.

When the bowl-shaped upper and lower molds 22 and 21 are brought into close contact with each other to squeeze fruit juice, the outer mold 22 has an escape space from the hole 2211 to the inside of the cylindrical body 223 as described above. In the embodiment, the top of the inner die 21 is provided with a tapered sharp portion 213 . Therefore, the tapered sharp portion 213 pierces the center portion of the half cross-section side of the substantially half-split fruit 8 , and can prevent the substantially half-split fruit 8 from falling off the surface of the inner mold 21 . . Further, when the molds 21 and 22 are separated from each other, the sharp portion 213 can hook the residue to make it easier to peel off from the outer mold 22, and when the upper and lower molds 22 and 21 are fitted to each other, , escapes into the cylindrical body 223 through the hole 2211, and there is no problem in mold matching.

Moreover, the sharp portion 213 includes a conical portion 2131 for piercing and holding the fruit 8 and a screw portion 2132 on the base end side thereof. By screwing a nut 212 on the rear surface through a hole 2111 , the sharp portion 213 can be replaced from the main body 211 . This is because the sharpened portion 213 is worn by being bent or rubbed against the vicinity of the entrance of the hole 2211 or the inner peripheral surface of the cylindrical body directly or with the pericarp in between. be. Therefore, by making the sharp portion 213 replaceable, the maintenance cost of the juice squeezing device 1 can be reduced.

Next, referring to FIG. 6, the residue removing device 5 will be described in detail. As described above, the residue removing device 5 includes the hooking member 51 on the first stage (upstream side) and the baffle plate 52 on the second stage (downstream side). It should be noted that the hooking member 51 is located on the flow path of the inner mold 21, at a position close to the flowing inner mold 21, and from the center of the inner mold 21, that is, from the tip of the conical portion 2131 of the sharp portion 213, It is provided only at the position of one side which is offset. In FIG. 6, the hook member 51 is formed like a blade, but it may be a claw (pin) or the like. With this configuration, the fruit 8 (residue) adsorbed to the inner mold 21 can be rotated around the sharp portion 213 to be peeled off from the inner mold 21, efficiently and reliably peeled off, and dropped. can be made

Moreover, the hooking member 51 is provided downstream of the position where the endless annular conveyors (33, 34) start folding back. This is because the hooking member 51 rotates the fruit 8 (residue) adsorbed to the inner mold 21 as described above and separates it from the inner mold 21, but the conveyer (33, 34) is in a position where it is horizontally conveyed. Even if it is provided in the inner mold 21, it may only be floated, but by providing it downstream from the position where the folding is started, the floated fruit 8 (residue) can be removed from the inner mold 21. , can be dropped more reliably. In this way, the fruits (residues) can be removed more efficiently and reliably.

Next, the baffle plate 52 will be described. The baffle plate 52 has a shape in which a rectangular plate close to the width of the four rows of inner molds 21 is spaced a predetermined distance from the outline of the four rows of inner molds 21 in the vertical cross section. The passage portion of the inner die 21 is cut out with a notch 521 so that it can be easily worn off and passed even when (33, 34) is conveyed. This makes it possible to more reliably remove the fruit 8 (residue) that has not been removed from the inner mold 21 by the hooking member 51 .

Moreover, the baffle plate 52 of the present embodiment is provided between the halfway point (horizontal position rotated by 90°) of the conveyor (33, 34) and the end point (lower end position rotated by 180°) of the conveyor (33, 34). . As a result, the baffle plate 52 and the hooking member 51 can reliably drop the peeled fruit 8 (residue) in two stages.
