  According to the invention described in claim 5, by using the wagon described in any one of claims 1 to 4, a steam cooker that does not require a baffle plate at the steam inlet of the treatment tank can be configured. it can.

  Furthermore, the invention according to claim 6 is configured such that the two faces facing the processing tank can be opened and closed by doors, and the steam cooker wagon with respect to the processing tank is positioned close to each door. 6. The steam cooker according to claim 5, wherein a stopper for positioning is provided.

  According to the invention described in claim 6, it is possible to realize a double door steam cooker including a processing tank with a stopper for positioning a wagon.

  According to the present invention, it is possible to provide a steam cooker wagon capable of hygienic and safe cooking at a low cost with a simple configuration, and a steam cooker in which the wagon is taken in and out.

Next, an embodiment of the present invention will be described.
The wagon of this embodiment is used for putting in and out foods (including food) in various steam cookers. The steam cooker includes a steam cooker and a steam cooler, as well as a saturated steam cooker that has the same configuration as that of the steam cooker but can be more automatically controlled. However, in this specification, this saturated steam cooking apparatus is also regarded as a kind of steaming machine or steaming cooler, and will be described as being included therein.

  The steam cooker of this embodiment controls a decompression means, a decompression means, a steam supply means, a discharge means, and each of these means in a sealable treatment tank, as in a conventionally known steamer or steam cooler. Control means are provided. Here, the decompression means is means for decompressing the inside of the processing tank by sucking and discharging the air in the processing tank to the outside. This decompression means is configured by providing a decompression pipe connected to the treatment tank with a vacuum pump, a steam ejector or a water ejector. The return pressure means is means for introducing outside air into the treatment tank under reduced pressure and restoring the pressure in the treatment tank. This return pressure means is configured by providing an opening / closing valve and a filter in a return pressure pipe connected to the treatment tank. The steam supply means is means for supplying (steaming) steam into the treatment tank and is configured to include a boiler. At this time, it is preferable to generate steam from soft water or pure water in a secondary boiler (reboiler) using steam from a general primary boiler as a heat source, and supply this clean steam into the treatment tank. The discharge means is means for discharging the steam in the treatment tank and its condensed water to the outside. This discharge means is configured by an openable and closable exhaust pipe or drain pipe connected to the treatment tank.

  On the other hand, the steam cooker of this embodiment does not need to provide a baffle plate at the steam outlet (steaming port) into the treatment tank, unlike a conventionally known steamer or steam cooler. That is, in the conventional steaming machine and steaming cooler, the baffle plate is provided at the steam inlet of the processing tank, but in this embodiment, instead of providing the baffle board in the processing tank, the baffle plate is provided in the wagon. A function is added. Therefore, the end of the steam supply pipe supplied with steam from the steam supply means may be connected to the treatment tank and remain open.

  Instead of providing a baffle plate at the steam inlet of the treatment tank, the upper surface of the wagon is closed. Further, the front and rear surfaces of the wagon are both closed continuously with the upper surface, and guides for guiding the condensed water of the steam generated on the upper surface to the lower side are provided on the left and right ends of the upper surface and the front and rear surfaces. This guide is continuously formed on the upper and lower left and right sides of the front and rear surfaces from the center of the upper surface to the lower edges of the front and rear surfaces.

  More specifically, the wagon of the present embodiment is typically formed in a substantially rectangular cylindrical shape with through holes arranged in the left-right direction, and both the upper and lower surfaces and the front and rear surfaces are closed. Further, if desired, one or a plurality of shelf boards are provided inside and away from each other. In addition, wheels (casters) are provided at the four corners of the lower part of the wagon so that the wagon can move freely.

  The wagon is formed in a substantially rectangular cylindrical shape with through holes formed in the left-right direction, and is open on both the left and right sides. Therefore, it is possible to put food in and out of the wagon through the left and right openings. In addition, the food can be cooked by steam supplied into the wagon through the left and right openings. Furthermore, the food can be cooled in a vacuum by evacuating the air in the wagon through the left and right openings.

  The guide provided in the wagon is typically shaped like a collar. That is, the guides are continuously provided on the upper surface and both front and rear surfaces of the wagon so as to extend in a plate shape outwardly perpendicular to the respective surfaces. Further, the upper surface of the wagon may be a horizontal surface, but is preferably an inclined surface in order to smoothly remove the condensed water of the steam. Specifically, the upper surface of the wagon is an inclined surface that gently slopes downward from the middle in the front-rear direction (usually the center in the front-rear direction) to the front and rear. The inclined surface may be formed to be inclined in only one direction from the front end side to the rear end side of the upper surface or from the rear end side to the front end side of the upper surface. In that case, the height dimension differs between the front surface and the rear surface.

  The shelf in the wagon (which may include the lower surface of the wagon itself) produces steam condensate, but the condensate is left and right to prevent this condensate from falling on the ingredients in the lower shelf. It is preferable to lead out to the outside in the front-rear direction without dropping from the opening. For this purpose, drainage holes are formed through the front and / or rear surface of the wagon. In the present embodiment, drainage holes are formed in the front and rear surfaces at the left and right ends of the height corresponding to the top surface of each shelf.

  By the way, you may form the protrusion for preventing the fall of the foodstuffs mounted on the shelf board in the right-and-left both ends of the shelf board of a wagon. And you may make it guide | induced condensed water to the said drain hole along this protrusion.

  Next, the usage method of the wagon of this embodiment is demonstrated. Wagon shelves are loaded with ingredients that you want to cook. In that case, foodstuffs may be put into various containers. The wagon on which the ingredients are placed is accommodated in a treatment tank of a steam cooker. In that case, a wagon is arrange | positioned in a processing tank so that the upper surface may oppose the steaming opening to a processing tank. And the foodstuff accommodated in the processing tank is cooked with the steam supplied in a processing tank. And depending on the case, after cooking, the inside of a processing tank is pressure-reduced and the said foodstuff is vacuum-cooled. Although the baffle plate is not provided at the steam inlet at the upper part of the treatment tank, the upper surface of the wagon itself functions as a baffle plate when steam is jetted toward the upper surface of the wagon. Then, the condensed water generated on the upper surface of the wagon is guided to the lower portion of the wagon by the action of the guide without falling on the food in the wagon.

  By the way, a steam cooker can be made into the double door type which provided the door in the side surface which a processing tank opposes, respectively so that opening and closing is possible. Specifically, the treatment tank is opened not only on the front surface but also on the rear surface, and the opening on the front surface can be opened and closed by the first door, while the opening on the rear surface can be opened and closed by the second door. And such a double door steam cooker can be used by providing it in the partition which divides a 1st chamber and a 2nd chamber. At that time, as long as the first door is directed to the first chamber and the second door is directed to the second chamber, and at least one of the doors is closed, the first chamber and the second chamber cannot communicate with each other. Is done. Moreover, it is preferable to control so that both doors do not open simultaneously.

  One of the first chamber and the second chamber can be a room for preparing food prior to steaming or steam cooling, and the other can be a room for vacuum cooling or serving food after steaming or steam cooling. For example, a wagon on which ingredients are placed in the first chamber is put into the treatment tank of the steam cooker from the first door, and is steamed or steam-cooled, and then led out from the second door to the second chamber. Then, in the second chamber, it is further cooled in a vacuum cooler and / or placed in various containers.

  The wagon is not only carried in from the first door and carried out to the second door, but on the contrary, if desired, it can be carried in from the second door and carried out to the first door for use. In either case, normally, the door on the carry-out side is closed, the door on the carry-in side is opened, and the wagon is placed in the processing tank. At that time, in order to open and close the unloading side door without hindrance at the time of unloading later, it is preferable that the wagon is not hit against the unloading side door. Specifically, a stopper for positioning the wagon with respect to the treatment tank is provided in the treatment tank at a position close to each door, and the wagon is inserted from the carry-in side with the stopper on the carry-out side functioning. It is done.

  The structure of the stopper is not particularly limited. For example, the stopper is composed of a bar provided on the side surface in the treatment tank so as to be opened and closed. And what is necessary is just to carry in a wagon in the state which has arrange | positioned the bar material by the side of carrying out in the horizontal position. When the wagon hits the bar, it is not pushed further to the carry-out side, and the wagon can be carried into the treatment tank without contacting the carry-out side door. And at the time of carrying out, a wagon should just be carried out in the state which opened the door of the carrying out side and has arrange | positioned the said bar in the vertical position. When the wagon moves in both directions between the first chamber and the second chamber, stoppers are provided at two locations corresponding to each door.

In addition, the front plate 9 and the rear plate 10 are formed in a substantially rectangular shape, which are separated from each other in the front-rear direction and are substantially vertically arranged facing each other. The front plate 9 or the rear plate 10 and the upper plate 7 or the front plate 9 or the rear plate 10 and the lower plate 8 are connected without a gap.

  The upper plate 7 of this embodiment is a gently inclined surface. Specifically, the upper plate 7 has the highest center portion in the front-rear direction, and is gently inclined downward as it goes outward in the front-rear direction. Thereby, the upper plate 7 is formed in a gentle triangular shape in a side view.

  The wagon 2 is provided with one or a plurality of shelf boards 11 that appropriately divide the interior thereof vertically. In the illustrated example, a single shelf 11 is provided at the center of the upper plate 7 and the lower plate 8. The shelf plate 11 is a plate material formed in a substantially rectangular shape, and is spanned between the front plate 9 and the rear plate 10 and held horizontally.

  A drainage hole 12 is formed through the front plate 9 and the rear plate 10 of the wagon 2 at a height corresponding to the shelf plate 11 and the lower plate 8. Specifically, drainage holes 12 are formed at the left and right ends of the height corresponding to the upper surfaces of the shelf board 11 and the lower board 8, respectively. In this embodiment, a substantially rectangular drainage hole 12 that is elongated to the left and right is formed, and the lower end of the drainage hole 12 corresponds to the upper surface of the shelf plate 11 or the lower plate 8. This drain hole 12 discharges the condensed water of steam generated on the shelf board 11 and the lower board 8 to the outside in the front-rear direction through the front board 9 and the rear board 10 when the wagon 2 is used in the steam cooker 1. To do.

  By the way, in order to prevent the article 13 (the container 15 containing the liquid food material 14 in the illustrated example) placed on the shelf board 11 and the lower board 8 from falling on the left and right side edges of the shelf board 11 and the lower board 8. A protrusion (not shown) or the like can be provided. And it can also comprise so that condensed water may be guide | induced to the said drain hole 12 along this protrusion.

  The upper plate 7, the front plate 9, and the rear plate 10 are continuously provided with brim-shaped guides 16 at the left and right side edges. Specifically, the upper plate 7, the front plate 9, and the rear plate 10 are provided with guides 16 extending continuously in a plate shape outwardly perpendicular to the respective plate surfaces. The guide 16 guides the steam condensate 17 generated in the upper plate 7 downward without dropping into the wagon 2 when the wagon 2 is used in the steam cooker 1.

  Casters 6 are provided at the four corners of the lower surface of the lower plate 8 of the wagon 2, respectively. Thereby, the wagon 2 is made movable. Although the structure of the caster 6 is not particularly limited, in the illustrated example, wheels 19 are rotatably held on an axle 18 arranged in the left-right direction. Thereby, in the present embodiment, the wagon 2 can be advanced and retracted in the front-rear direction. However, the wheel 19 of the caster 6 may be configured to be turnable around an attachment shaft (not shown) along the vertical direction.

  Next, an example of the steam cooker 1 in which the wagon 2 is taken in and out will be described. As shown in FIG. 5, the steam cooker 1 of the present embodiment includes a treatment tank 3 in which the wagon 2 is accommodated and can be sealed, a steam supply means 40 for supplying steam into the treatment tank 3, and the treatment tank Pressure reducing means 41 for reducing the pressure in the processing tank 3 by sucking and discharging the air and steam inside the processing tank 3, and a pressure reducing means 42 for introducing outside air into the processing tank 3 under reduced pressure and returning the pressure in the processing tank 3. , A discharge means 43 for discharging the steam in the treatment tank 3 and its condensed water to the outside, and a control means 44 for controlling these means.

  Here, the processing tank 3 is a box-shaped metal can having a substantially rectangular hollow portion that is slightly larger than the wagon 2. The decompression means 41 is configured by providing a decompression pipe connected to the processing tank 3 with a vacuum pump, a steam ejector, a water ejector, or the like. The return pressure means 42 is configured by providing an on-off valve and a filter in the return pressure pipe connected to the processing tank 3. The steam supply means 40 includes a steam supply valve in the steam supply pipe 20 from the boiler. At this time, it is preferable to generate steam from soft water or pure water in a secondary boiler (reboiler) using steam from a general primary boiler as a heat source, and supply this clean steam into the treatment tank 3. The discharge means 43 includes an openable / closable drainage pipe and a steaming pipe connected to the treatment tank 3.

  Such a steam cooker 1 can employ a configuration of a conventionally known steamer or steam cooler, but as shown in FIG. 1, for steaming supplying steam from the steaming means 40 into the treatment tank 3. The pipe 20 does not need to be provided with a baffle plate at the opening (steaming port) 21 into the processing tank 3. That is, in the present embodiment, the steam supply port 21 is disposed at the center of the upper wall of the processing tank 3. And when the wagon 2 is accommodated in the predetermined position in the processing tank 3, the steam supply port 21 is comprised so that the center part of the upper board 7 of the wagon 2 may be opposed. As a result, steam is ejected toward the center of the upper plate 7 of the wagon 2. Since the wagon 2 is, as described above, the upper plate 7, the front plate 9, and the rear plate 10 are closed on the upper surface and both the front and rear surfaces, and the flange-shaped guides 16 protrude from the left and right edges. These structures serve as a baffle plate.

  By the way, the processing tank 3 of a present Example is made into the double door type which has the doors 22 and 23 in both the front surface and a rear surface. That is, as shown in FIG. 1, the treatment tank 3 has openings on two faces facing each other, one opening can be opened and closed by the first door 22, and the other opening can be opened and closed by the second door 23. It is possible. And each door 22 and 23 can block | close the opening part of the processing tank 3 in the airtight state via the packing 24. FIG.

  Such a double door type processing tank 3 can be used by being provided in a partition wall (not shown) separating the first chamber and the second chamber. At that time, as long as the first door 22 faces the first chamber and the second door 23 faces the second chamber and at least one of the doors is closed, the first chamber communicates with the second chamber. Impossible. Moreover, it is preferable to control so that both doors 22 and 23 do not open simultaneously.

  Stoppers 25 are provided on the side walls in the processing tank 3 at positions close to the first door 22 and the second door 23, respectively. 3 and 4 are perspective views showing the stopper 25 of this embodiment. FIG. 3 shows the operating state of the stopper 25, and FIG. 3 and 4 show only the front-side stopper (stopper of the second door 23) 25 in FIG. 2, the back-side stopper (stopper of the first door 22) 25 is symmetrical with respect to this. It is the same structure only by becoming a shape. The stopper 25 of the present embodiment is configured by a substantially cylindrical case 26 in which a substantially columnar movable material 27 is rotatably accommodated.

  The case 26 has a substantially cylindrical shape, and is provided on a side wall in the processing tank 3 with a peripheral side surface fixed. At that time, the substantially cylindrical case 26 is arranged with its axis horizontally. Although the mounting height of the case 26 with respect to the processing tank 3 is not particularly limited, in the illustrated example, it is approximately the center in the vertical direction. At both ends in the longitudinal direction of the case 26, substantially rectangular notches 28 and 29 are formed so as to open to the end surface of the case 26. 3 and 4, the first notch 28 shown on the front side (the opening side of the processing tank 3) is formed to open vertically upward. On the other hand, in FIG. 3 and FIG. 4, the second cutout 29 shown on the back side is cut out by about 90 degrees in the circumferential direction from vertically upward to the inside of the treatment tank 3.

  On the other hand, the movable member 27 has a cylindrical portion 30 that is rotatably fitted in the case 26. At both ends in the longitudinal direction of the cylindrical portion 30, the movable member 27 extends radially outward from the peripheral side surface, and a stopper bar 31. And a positioning rod 32 are provided. In the present embodiment, the stopper bar 31 and the positioning bar 32 are provided at positions corresponding to the circumferential direction of the cylindrical portion 30. That is, the stopper bar 31 and the positioning bar 32 are provided at corresponding positions separated in the front-rear direction. 3 and 4, the stopper bar 31 shown on the near side is formed sufficiently longer than the positioning bar 32 shown on the back side. The positioning rod 32 has a length that extends slightly from the outer peripheral surface of the case 26 in the state of being accommodated in the second notch 29.

  The column part 30 of the movable member 27 is formed longer than the longitudinal dimension of the substantially cylindrical case 26, and the movable member 27 can move forward and backward with respect to the case 26. The width dimension (circumferential dimension) of the first notch 28 is slightly larger than the diameter of the stopper bar 31. As shown in FIG. 4, the movable member 27 is accommodated in a state where a stopper bar 31 is disposed in the first notch 28. In this state, the stopper bar 31 and the positioning bar 32 are each arranged vertically upward.

  On the other hand, in order to operate the stopper 25, as shown in FIG. 3, the stopper bar 31 and thus the cylindrical part 30 may be pulled out to the front side to bring the stopper bar 31 into a horizontal state. At this time, the positioning bar 32 rotates in the second notch 29, the positioning bar 32 comes into contact with the circumferential end surface of the second notch 29, and the stopper bar 31 is positioned with respect to the case 26. As shown by the two-dot chain line in FIG. 3, the wagon 2 is positioned by the stopper rod 31 held horizontally in this way, as shown by the two-dot chain line.

  The case where the foodstuff 14 is steamed or steam-cooled (vacuum cooled after steaming) using the wagon 2 or the steam cooker 1 will be described. The food 14 to be steamed or steam-cooled is not particularly limited, but in the illustrated example, the liquid food (including liquid food) 14 is placed in a bottomed container 15 opened upward and processed. Show. Such liquid food materials 14 include, for example, curry roux, ramen soup, boiled foods and the like. Here, the upper opening of the container 15 may be covered with a moisture-permeable waterproof sheet (not shown) having the property of allowing vapor to pass but not water.

  The wagon 2 on which the food material 14 is placed on the shelf board 11 and the lower board 8 is accommodated in the treatment tank 3 of the steam cooker 1. Here, the first door 22 will be described as the carry-in side, and the second door 23 will be described as the carry-out side. Prior to opening the first door 22 and carrying the wagon 2 into the processing tank 3, the stopper 25 on the second door 23 side is first operated. That is, the stopper bar 31 is lowered to the horizontal state manually through the second door 23. Then, the wagon 2 is carried into the processing tank 3 with only the first door 22 opened. Even if the wagon 2 is fully pushed into the processing tank 3, the wagon 2 cannot be advanced any further because the guide 16 at the front end of the wagon 2 hits the stopper bar 31, and the wagon 2 to the second door 23 cannot be advanced. Is prevented from touching. Therefore, when opening the second door 23 later, there is no possibility that the opening operation will be hindered.

  In this way, after the wagon 2 is accommodated in the treatment tank 3, the first door 22 is closed, and the food 14 in the treatment tank 3 is steamed or steam-cooled. For steaming, after the air in the processing tank 3 is removed by the decompression means 41, steam is supplied into the processing tank 3 by the steam supply means 40. Although the baffle plate is not provided at the steam supply port 21 to the treatment tank 3, the upper plate 7 of the wagon 2 functions as a baffle plate. The steam condensate generated on the upper plate 7 of the wagon 2 is guided to the front plate 9 and the rear plate 10 by the upper plate 7 being inclined, and dropped to the lower portion of the wagon 2. At this time, since the brim-shaped guide 16 is provided, there is no possibility that the condensed water falls to the food material 14 in the wagon 2. Similarly, the condensed water generated in the shelf plate 11 and the lower plate 8 is led out of the wagon 2 from the drain hole 12.

  After the completion of cooking, the inside of the processing tank 3 is returned to the atmospheric pressure by the discharge means 43 and the return pressure means 42. However, when vacuum cooling is performed after cooking, the air in the processing tank 3 is led out of the processing tank 3 by the decompression means. Thereby, the foodstuff 14 heat-cooked by the said steaming can be vacuum-cooled. After the vacuum cooling, the inside of the processing tank 3 is returned to the atmospheric pressure by the decompression means 42.

  After being steamed or steam-cooled in this way, the second door 23 is opened and the stopper 25 is returned to the storage position, and then the wagon 2 can be carried out from the processing tank 3. By the way, although the example which carries out the wagon 2 carried in from the 1st door 22 from the 2nd door 23 was demonstrated here, conversely, the wagon 2 is carried in from the 2nd door 23, and from the 1st door 22 It can also be carried out. In that case, with the stopper bar 31 on the first door 22 side lowered in advance, the second door 23 is opened, the wagon 2 is carried in, and the second door 23 is closed and steaming or steaming is performed. Thereafter, the wagon 2 may be carried out from the first door 22.

  The steam cooker wagon 2 and the steam cooker 1 of the present invention are not limited to the configuration of the above-described embodiment, and can be changed as appropriate. In particular, the food material 14 processed by the wagon 2 or the steam cooker 1 is not limited to a liquid food material. Moreover, the presence or absence of the container 15 into which the foodstuff 14 is put, the configuration of the container 15, the presence or absence of a moisture-permeable waterproof sheet, and the like can be changed as appropriate.

  Furthermore, in the said Example, although the doors 22 and 23 were provided in the two places which face the process tank 3, like the conventionally well-known general steaming machine and steaming cooler, one door may be sufficient. In that case, in the case where the inner bottom surface of the treatment tank 3 is not inclined, the stopper 25 can be omitted. Further, even when the double door type is used as in the above embodiment, the stopper 25 is not necessarily required. In particular, when the directions on the carry-in side and the carry-out side are fixed, the treatment is always performed in only one direction, and the fixed surface in the treatment tank 5 is not inclined, the stopper 25 can be omitted in the vicinity of the door on the carry-in side. . Specifically, in the above embodiment, the first door 22 is always used as a carry-in port, and the second door 23 is always used as a carry-out port. In any case, the configuration of the stopper 25 can be changed as appropriate.
