Description

  The present invention relates to a cooking device capable of cooking a material into a higher quality product and a floating foreign substance removing device used therefor. However, in this invention, heat cooking is a generic term for fried processing with oil, boil processing with water, boiled processing, stew processing or boiled processing with seasoning liquid (boiled liquid), and is used for heat cooking. Oil, water, seasoning liquid, etc. are collectively called heating liquid.

  There has been proposed a fryer capable of fried high-quality fried food such as fried food and tempura (Patent Document 1).

This is configured by arranging a horizontally circulating chain in the center of an oval track-like tank and attaching an outward flag-shaped apron to the chain at an equal pitch. In addition, the circulation running path of the chain is higher than the liquid level of the heating liquid in the tank, and each apron is immersed in the heating liquid in the tank so that the inside of the tank can be partitioned into a plurality of cells. Therefore, this material can convey the material put into each cell separately for each cell, and it can be fried by frying oil in the tank, and the cell into which the material is put and the fried product are discharged Optimum frying time can be easily realized by appropriately selecting the distance from the cell. In addition, this thing can fully be used also for heat cooking other than frying by using water or a seasoning liquid instead of fried oil.
JP 2006-34391 A

  When such conventional technology is used, since each cell partitioned by the apron is open at the top, the material that easily floats on the liquid surface of the heating liquid has poor heat flow and may cause uneven cooking. In addition, there is a problem that the quality appearance of the product may be impaired when floating foreign matters such as fat and lye leaching from the material during cooking are accumulated on the liquid surface of the heating liquid.

  Therefore, in view of the problems of the prior art, the object of the present invention is to add a presser device to improve the heat flow to the material and realize uniform cooking, and also a heating tank, an intermediate tank, a replenishing tank By combining the circulation pump, the floating foreign material on the liquid surface of the heating liquid can be easily removed, and the cooking device that can further improve the quality of the product and the floating foreign material removal device used for the cooking device It is to provide.

  The structure of the 1st invention concerning this application for achieving this object (referring to the invention according to claim 1, hereinafter the same) consists of dividing the tank containing the heating liquid and the material in the tank for each cell. The conveyance device includes a conveyance device that conveys and a presser device that interlocks with the conveyance device. The conveyance device includes a first chain that circulates horizontally and a flag-like apron that is attached to the first chain at an equal pitch. The apparatus has a second chain that circulates vertically and a press plate that is attached to the second chain at the same pitch as the apron, and the material in each cell partitioned by the apron is placed in the heated liquid via the press plate. The gist is to transport while submerging.

  The configuration of the second invention (referred to the invention according to claim 2, hereinafter the same), a heating tank with a built-in heater for receiving the heating liquid overflowing from the tank of the cooking device, an intermediate tank for receiving the heating liquid overflowing from the heating tank, The gist of the invention is to include a replenishing tank for quantitatively replenishing the heating tank with fresh heating liquid and a circulation pump for supplying the heating liquid from the heating tank to the tank.

  In the heating tank, the heating liquid from the replenishing tank can be introduced below the liquid level via the guide tube, and a mesh for separating floating foreign matters can be provided in the intermediate tank.

  According to the configuration of the first invention, the transfer device can be formed by partitioning a plurality of cells in the tank via a flag-like apron attached to the first chain at an equal pitch, and the material in the tank Can be transported separately for each cell. That is, the conveying device can classify the material put into the cell for each cell, convey the heated liquid, and appropriately cook with the heated liquid. On the other hand, the presser device conveys the material in each cell through the presser plate attached to the second chain while being submerged in the heating liquid, so that heat is evenly passed through the material being cooked, and uneven cooking is performed. Can be eliminated. Since the presser device is linked with the transport device, the relative positional relationship between each presser plate and each cell can be maintained constant, and the material in each cell can be reliably submerged in the heating liquid. However, it is not necessary for the presser device to submerge the material in each cell in the heating liquid for the entire cooking process by the conveying device, for example, to submerge the material only for half or less of the final stage of the cooking process. It is generally sufficient to arrange.

  According to the configuration of the second invention, the circulation pump supplies the heating liquid heated to a predetermined temperature by the heater in the heating tank to the tank, continuously overflows the heating liquid in the tank from the tank, The floating foreign matter that floats on the liquid surface of the heating liquid is caused to flow into the heating tank together with the heating liquid. On the other hand, since the heating tank is replenished with a fixed amount of fresh heating liquid from the replenishing tank, the floating foreign matter flowing out into the heating tank is discharged to the intermediate tank together with the heating liquid overflowing from the heating tank, and is passed through the circulation pump. It will not return to the tank again. The heating liquid overflowing from the heating tank is equivalent to the fixed amount of fresh heating liquid from the replenishing tank, and can be suppressed to the minimum necessary. In addition, heating liquid corresponding to the discharge amount of the circulation pump is supplied from the heating tank into the tank, and the same amount of heating liquid flows out continuously to the heating tank. Therefore, a flow of the heating liquid corresponding to the circulation amount by the circulation pump is formed in the tank, and the floating foreign matter on the liquid surface can be effectively discharged to the heating tank.

  The floating foreign material flowing out from the tank floats on the liquid surface of the heating liquid in the heating tank. Therefore, by introducing the heating liquid from the replenishing tank below the liquid level via the guide tube, the fresh heating liquid does not flow out of the heating tank together with floating foreign substances, and the consumption of the heating liquid is minimized. Can be suppressed.

  The mesh provided in the intermediate tank separates floating foreign substances flowing out from the heating tank together with the heating liquid, and can easily process the used heating liquid stored in the intermediate tank.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The cooking device is configured by combining the transport device 10 and the presser device 20 with respect to the tank 31 in which the heating liquid W is stored (FIGS. 1 and 2).

  The curved portion after the tank 31 rises obliquely via the slopes 31a and 31a. A product discharge chute 31b is formed in the rear curved portion via a slope 31a on the front plate 33 side, and the heated liquid W in the tank 31 passes through the outflow holes 31c, 31c. A discharge rod 31d is formed for overflowing and discharging to the outside. However, a dam plate 31e that defines the level of the heating liquid W in the tank 31 is provided upright at the tip of the discharge rod 31d. A groove 31g is continuously formed on the bottom surface of the tank 31 between the rear end of each straight line portion and the slopes 31a, 31a, and a discharge port 31h for the heating liquid W is formed on the bottom surface of the groove 31g. It is open. In addition, supply ports 31m, 31n, and 31n for the heating liquid W are opened on the side wall of the groove portion 31g on the front plate 33 side and the bottom surface of the curved portion in front of the tank 31, respectively.

  The conveying device 10 is configured by attaching flag-like aprons 12, 12,... Outward at equal pitches to the endless first chain 11 that circulates horizontally. In addition, the 1st chain 11 is installed in the position higher than the liquid level of the heating liquid W in the tank 31 between the linear parts of the tank 31. FIG.

  The first chain 11 is a three-dimensional chain that bends up, down, left, and right by alternately connecting the upper, lower, left, and right link plates 11b, 11b through the pieces 11a, 11a,. 3A and 3B are exploded perspective views of main parts of the first chain 11 and the transport device 10, respectively. The piece 11a is cut out in parallel planes on the top, bottom, left and right of the sphere, and the top, bottom, left, and right link plates 11b, 11b,... Are rotatably connected to the respective planes of the piece 11a via connecting pins (not shown). Each piece 11a is provided with rollers 11c and 11c in the vertical direction and the horizontal direction so as to be rotatable alternately every two pitches via respective connecting pins.

  Each apron 12 is configured by forming long and short long holes 12a, 12a... In a row at the bottom of a horizontally long plate material. The apron 12 is detachably attached to the first chain 11 via a bracket 12b. The bracket 12b is formed by inserting the extension portions 11d and 11d of the connecting pins for the upward rollers 11c and 11c of the adjacent first chain 11 at predetermined intervals into the round holes 12b1 and the long holes 12b2 on the upper horizontal side. The first chain 11 is hooked. A tab-like protrusion 12b3 is formed on the rear side of the vertical side of the bracket 12b. The protrusion 12b3 abuts the tip of the connecting pin for the horizontal roller 11c adjacent to the rear, and the apron 12 is prevented from tilting backward in the direction of travel. A support bar 12c attached to the upper side of the apron 12 is erected at the lower part of the vertical side of the bracket 12b, and a roller 12d is attached to the tip of the support bar 12c.

  The first chain 11 is wound around two sprockets 13, 13 ... before and after engaging with the upper and lower rollers 11c, 11c ... (Figs. 1 and 2).

  The rear sprockets 13 and 13 on the discharge chute 31b side are inclined and disposed on the slopes 31a and 31a, and the front sprockets 13 and 13 on the discharge rod 31d side are horizontally disposed, It is connected to a variable speed drive motor (not shown) installed in the motor. Therefore, the first chain 11 can move the aprons 12, 12,... Around the tank 31 all at once (in the directions of the arrows K1 in FIGS. 1 and 2). The tip of each apron 12 that crosses the part is supported via a roller 12 d that rolls on the outer edge of the tank 31. Further, the first chain 11 is guided at a straight traveling portion by a guide 31f disposed along the inner edge of the tank 31 (FIG. 3B), and is near a sprocket 13 and 13 by a press guide (not shown). It is bent obliquely upward along the slopes 31a and 31a (FIG. 1).

  The apron 12, 12 ... in the tank 31 partitions the tank 31 into a plurality of cells C, C ... (FIG. 2). However, each cell C is a rectangle determined by the width of the tank 31 and the pitch of the aprons 12, 12... In the straight part of the tank 31, and opens in a fan shape in the curved part before and after the tank 31. In addition, in the tank 31, the heating liquid W is so deep that all of the short long holes 12a, 12a... Of each apron 12 sink and about 1/2 to 2/3 of the long long holes 12a, 12a. It shall be stretched. Therefore, for example, when the material is sequentially introduced into the cells C, C... At the position of the arrow A in FIG. It can be transported through the part, and the material can be continuously cooked by the heating liquid W, and automatically discharged to the outside as a cooked product via the slope 31a and the discharge chute 31b on the front plate 33 side. (In the direction of arrow B in FIG. 2).

  The presser device 20 is configured by attaching presser plates 22, 22... To a pair of second chains 21, 21 that circulate vertically (FIGS. 1 and 2). The holding device 20 is disposed above the straight portion of the tank 31 on the discharge chute 31b side, and the holding plates 22, 22... Are attached to the first chain 11 with respect to the second chains 21, 21. 12, 12... Are attached at the same pitch. The second chains 21 and 21 are wound around the front and rear sprockets 23 and 23, respectively.

  The shafts 23a, 23a for the front and rear sprockets 23, 23... Are installed on the frame members 23c, 23c via bearings 23b, 23b, respectively (FIGS. 1 and 4). One frame member 23c is fixed on the travel path of the first chain 11 via a bracket 23d, and the other frame member 23c is fixed to the front plate 33. However, the bracket 23d is supported via spacers 23d1 and 23d1 at both ends. The front shaft 23 a on the discharge rod 31 d side is connected to the shaft 13 a of the sprocket 13, 13 for the first chain 11 via bevel gears 24, 24.

  Each presser plate 22 has a rectangular plate material in which a large number of long holes 22a, 22a,... Are arranged in an obtuse angle along both long sides, and is formed into a cross-sectional mountain shape (FIGS. 4 and 5). . However, in FIG. 4, FIG. 5, the state which the presser plate 22 exists in the lower running part and the upper running part of the 2nd chains 21, 21 is shown in figure, respectively.

  A weight 22b is attached to the inside of the presser plate 22, and both legs of a support rod 22c that is bent into a portal shape are screwed. Further, a channel-like support member 21b is installed on the second chains 21 and 21 via attachments 21a and 21a, and both legs of the support rod 22c are inserted into the support member 21b so as to be relatively movable. Guide pipes 22d and 22d are erected. Note that the frame members 23c and 23c that support the shafts 23a and 23a have their lower ends folded back toward the second chains 21 and 21 to support and guide the lower traveling portions of the second chains 21 and 21. However, the presser plate 22 may be assembled so as to be movable relative to the support member 21b in the vertical direction, and the support rod 22c is formed as two bars corresponding to both legs, so as to be prevented from being removed from the support member 21b. May be.

  The presser device 20 is interlocked with the transport device 10 via bevel gears 24 and 24. Therefore, when the transport device 10 is operated in the directions of the arrows K1 in FIGS. 1 and 2, the presser device 20 is driven in the direction of the arrow K2 in FIG. 1, and the presser is moved through the lower travel portions of the second chains 21 and 21. The plates 22, 22... Can be moved at the same speed in the same direction as the aprons 12, 12,.

  On the other hand, the presser plates 22, 22... Are mounted on the second chains 21 and 21 at the same pitch as the aprons 12, 12. Each presser plate 22 is made to correspond exactly to (two-dot chain line in FIG. 2), and the material in each cell C can be conveyed toward the discharge chute 31b while being submerged in the heating liquid W. In the lower traveling portion of the second chain 21, 21, each presser plate 22 is moved by the weight of the support rod 22c relative to the guide pipe 22d, 22d by its own weight including the weight 22b. This is because the material 21b greatly falls below the material 21b (FIG. 4). In addition, since each presser plate 22 is inverted and dropped by its own weight at the upper traveling portion of the second chain 21, 21, only the length of the guide pipes 22d, 22d protrudes on the second chain 21, 21 and the support member 21b. (FIG. 5).

  A regulating member 25 attached to the front plate 33 via the bracket 25a is disposed on the discharge rod 31d side of the presser device 20 (FIGS. 1 and 2).

  The restricting member 25 is formed by bending a band plate material, and is disposed with the tip portion obliquely inserted below the shaft 23a for the sprocket 23, 23 on the drive side of the presser device 20 (FIG. 6). Therefore, when the second chain 21, 21 moves from the upper traveling portion to the lower traveling portion around the sprockets 23, 23, the regulating member 25 is configured so that each apron 12 of the transport device 10 is a curved portion in front of the tank 31. The pressure plate 22 is controlled to fall so that the pressure plate 22 falls into the cell C after the rectangular cell C is formed. This is because the material in the cell C may not be properly submerged in the heating liquid W when the press plate 22 falls too early and the cell C opens in a fan shape. That is, the front end portion of the regulating member 25 engages with the lower surface of each presser plate 22, and the presser plate 22 can be prevented from dropping until the presser plate 22 sufficiently advances into the straight portion of the tank 31.

  A floating foreign matter removing device including a heating tank 41, an intermediate tank 42, a replenishing tank 43, and a circulation pump 44 is disposed on the outlet side of the discharge tank 31d of the tank 31 (FIGS. 7 and 8).

  The heating tank 41 can receive the heating liquid W overflowing from the tank 31 through the discharge rod 31d. In the heating tank 41, a heater H is built in, a discharge rod 41a is formed, and a long guide cylinder 41b is built up and down. The guide cylinder 41 b opens on the liquid level of the heating liquid W in the heating tank 41 and opens near the bottom of the heating tank 41. Further, the intermediate tank 42 is disposed so as to receive the heating liquid W overflowing from the heating tank 41 through the discharge rod 41a. The intermediate tank 42 is formed with a discharge gutter 42a, and a mesh 42b for filtering the heated liquid W from the heating tank 41 is detachably mounted. A waste liquid tank 45 is disposed on the outlet side of the discharge tank 42a.

  The suction side of the circulation pump 44 is connected to the bottom of the heating tank 41. The discharge side of the circulation pump 44 is branched and connected to the supply ports 31m, 31n, 31n of the heating liquid W opened on the side wall and bottom surface of the tank 31. A drain valve 31k is attached to the outlet 31h for the heating liquid W that opens in the groove 31g of the tank 31.

  Fresh heating liquid W1 from the storage tank 46 flows into the replenishing tank 43. However, the liquid level of the heating liquid W1 in the replenishing tank 43 is kept constant via the float valve 46a. Further, the fresh heating liquid W1 from the replenishing tank 43 is introduced below the liquid level of the heating liquid W in the heating tank 41 through the on-off valve 43a and the guide cylinder 41b in the heating tank 41.

  When the circulation pump 44 is operated, the heating liquid W heated to an appropriate temperature by the heater H is supplied to the tank 31 via the supply ports 31m, 31n, 31n, and the heating liquid W overflowing from the tank 31 is heated via the discharge rod 31d. Return to tank 41. Therefore, in the tank 31, the groove 31g from the supply port 31g and the straight portion far from the discharge chute 31b reach the previous curved portion, and merge with the heating liquid W from the supply ports 31n and 31n to discharge the waste 31d. As a result, a flow of the heating liquid W flowing out is generated, and floating foreign matters such as fat and lye resulting from the material being cooked are discharged to the heating tank 41 together with the heating liquid W through the discharge basket 31d. At this time, the heating liquid W flowing out from the discharge rod 31d corresponds to the discharge amount of the circulation pump 44.

  On the other hand, the heating tank 41 is replenished with a fixed amount of fresh heating liquid W1 from the replenishing tank 43 via the on-off valve 43a, and the heating liquid W corresponding to a fixed amount of replenishing quantity from the heating tank 41 via the discharge rod 41a. To be discharged. Therefore, floating foreign substances on the liquid surface of the heating liquid W in the heating tank 41 are discharged to the intermediate tank 42 together with the heating liquid W from the heating tank 41 and are accumulated on the mesh 42b. Therefore, the floating foreign material on the mesh 42b and the used heating liquid W flowing out from the intermediate tank 42 to the waste liquid tank 45 through the discharge tank 42a can be separately separated and processed.

  In the above description, the aprons 12, 12,... Attached to the first chain 11 can be provided in any number of equal pitches according to the circumferential distance of the tank 31. Further, the heating tank 41, the intermediate tank 42, the replenishing tank 43, and the storage tank 46 may be deformed into arbitrary shapes including a round tank, regardless of FIGS. 7 and 8, and the heater H in the heating tank 41 may be modified. It is preferable to devise the shape and arrangement so that the heating liquid W in the heating tank 41 is heated as uniformly as possible. In addition, the heater H shall control the heating temperature of the heating liquid W in the heating tank 41 in combination with an appropriate temperature control device. Further, the guide tube 41b may be a long hose or pipe that is connected to the outlet side of the on-off valve 43a and reaches at least near the bottom of the heating tank 41, instead of being incorporated in the heating tank 41.

  7 and 8 can be suitably applied to any type of cooking apparatus other than those shown in FIGS.
