Description

  The present invention relates to a cook chill system that provides food that has been refrigerated and stored by reheating to a predetermined temperature, and a food cart having a heat retaining function suitable for the system.

  In order to provide meals at hospitals, geriatric health facilities, hotels, schools, etc., a distribution car or a distribution cart is used. At the time of distribution, pre-cooked food (including ingredients) is temporarily kept at around 3 ° C. Refrigerated storage is carried out, and the refrigerated food is reheated to a safe temperature of 75 ° C. and then distributed.

  Here, the distribution vehicle is a plurality of trays arranged in a horizontal direction and a vertical direction in a heat storage, and at least a heating device for maintaining the temperature in the heat storage in a certain range, and as required. An arrangement cart includes a cooling device. A distribution cart conveys a plurality of trays arranged in a horizontal direction and a vertical direction, and does not include a heating device or a cooling device. In addition, the distribution cart includes both those having a heat retaining function and those not having a heat retaining function.

  The food to be served includes not only heated food but also food refrigerated at a low temperature. On the other hand, as in the above hospitals, it is necessary to distribute a large amount of food within a short period of time. Therefore, before cooking, food that has been heat-treated and food that has not been heat-treated are arranged in one tray. Is a problem in the kitchen business operation. Therefore, the tray is divided into a heating space in which foods to be heated are loaded in advance and a non-heating space in which foods that are not heated are loaded. Food that is to be heat-treated is designated as a heating space, and food that is not heat-treated is designated as a non-heating space. In addition, it is proposed that the food is distributed and placed in a refrigerated state, and only the heating space is heated locally before cooking, and only the food in the heating space is cooked (Cook Chill). .

  In Patent Document 1, the food in the heating space is heated using induction heating, but special tableware suitable for induction heating must be prepared, the size and arrangement of the tableware are limited, and Since it is difficult to uniformly heat the inside of the food, there are problems such as limited menus that can be heat-treated.

  In view of this, the present applicant in Patent Document 2 is provided with a warm storage (also reheating storage) and a refrigerator, and reheats the food stored in the warm storage by blowing warm air of 120 to 130 ° C. It proposes a cook chill type trolley. However, since the heating device and the cooling device are mounted on the mobile trolley, the problem that the failure of the heating device and the cooling device inevitably increases compared to the fixed type is unavoidable.

  FIG. 7 shows a cook chill system in which a heating device and a cooling device 50 are fixed and a food cart 51 provided with a heat storage is connected to the heating device and the cooling device 50 to refrigerate and reheat food in the heat storage. Shown (unpatented or unpublished). This system has the advantage that the possibility of failure of the heating device and the cooling device is reduced because only the layout cart 51 without the heating device and the cooling device moves. On the other hand, as shown in FIG. 7, the food cart 51 is connected to the heating device and the cooling device 50 with one door of the food cart open, so that the food on all trays 52 in the food cart 51 is uniform. There is no guarantee that it will be heated. Specifically, when the trays 52 are arranged in a plurality of rows in the horizontal direction, when the food on the tray 52a on the side closer to the heating device and the food on the tray 52b on the side far from the heating device are compared, Since the heating conditions are different, there is a high possibility of uneven heating.

  According to the first aspect of the present invention, when the food is placed on the tray and reheated in the reheating chamber, the entire partition frame from which the heat insulating cover is removed is inserted into the reheating chamber. Unlike the conventional cook chill system shown, the food on all trays mounted on the divider frame can be heated almost uniformly. Moreover, since the partition frame is actually composed only of a metal frame and has no walls, its own heat capacity is smaller than that of the heat storage, and energy loss during reheating is small. Furthermore, when it is pulled out from the reheating chamber, the possibility that the operator accidentally touches the high temperature part is small, and the safety is high. Furthermore, since a rectangular parallelepiped heat insulation is formed simply by attaching a heat insulation cover made of, for example, a heat insulating material to the partition frame, the temperature of the cooked food can be kept within a certain range at the time of serving. . In addition, since the heating device (if necessary, the cooling device) is fixed, the probability of failure is lower than that mounted on the trolley.

  According to the invention of claim 2, when the tray is taken out from the layout cart at the time of the layout, the open / close door is opened in a double door, so that the protruding amount of the open / close door is small and can be distributed through a narrow passage.

  A cook chill system according to an embodiment of the present invention and a serving cart equipped with a heat retaining function suitable for the cook chill system will be described with reference to the drawings. The cook chill system according to the present embodiment fixes and installs a reheating cabinet that also serves as a refrigerator, and allows a partition frame holding a large number of trays to be inserted into and withdrawn from the reheating cabinet and pulled out from the reheating cabinet. A thermal insulation cover is attached to the partition frame and used as a food cart.

  FIG. 1 shows a state where the door 8 of the reheating chamber 1 according to the present embodiment is closed, and FIG. 2 shows a state where the door 8 of the reheating chamber 1 is opened. The reheating chamber 1 includes, for example, a storage 2 that can store two partition frames 10, a heating device 3 that supplies warm air to the storage 2, a cooling device 4 that supplies cold air to the storage 2, and a heating temperature. An operation panel 5 for setting the temperature and the refrigeration temperature, a control device 6 for controlling the heating device 3 and the cooling device 4 according to the set temperature, an operation panel 5 for setting the heating temperature and the refrigeration temperature, etc. It consists of In addition, a duct and a fan for guiding hot air or cold air from the heating device 3 or the cooling device 4 are provided around the storage 2 (not shown).

  Two doors 8 for covering the opening of the storage 2 are attached to the front surface of the reheating chamber 1 via hinges, and the doors 8 can be folded into two by hinges. The storage 2 of the reheating chamber 1 is apparently divided into two spaces 2a and 2b corresponding to the partition frame 10 and the two doors 8, and the partition frames 10 are mounted in the spaces 2a and 2b, respectively. Is done.

  The tray 9 used in the present embodiment includes a heating space 9a in which food to be heated is mounted and a non-heating space 9b in which food that is not heated is mounted. The partition frame 10 corresponds to the structure of the tray 9, and the side walls 10a and 10b of the partition frame 10 are configured so that the trays 9 can be accommodated in, for example, two rows in the horizontal direction and a plurality of levels in the vertical direction. Horizontal guide rails that are engaged with both side walls in the arrangement direction of the heating space 9a and the non-heating space 9b are formed. Further, a vertical heat insulating wall 10c is provided near the center of the partition frame 10 (not necessarily in the center), and the heat insulating wall 10c has a heating space 9a of the tray 9 corresponding to the guide rail. A plurality of horizontal slits into which the partition portions between the non-heating spaces 9b are inserted and a movable plate that is displaced in the vertical direction for closing the slits are provided (not shown for obvious reasons).

  When the partition frame 10 is mounted in the two spaces 2a and 2b, the spaces 2a and 2b are divided into the first heat storage chambers 31 and 32 and the second heat storage chambers 41 and 42 by the heat insulating wall 10c. The 1st heat storage 31 and 32 can be used by switching to either a reheating storage or a refrigerator, and the 2nd heat storage 41 and 42 is used exclusively as a refrigerator. In addition, in the configuration example shown in FIG. 2, it apparently has four heat storages, but since the two first heat storages 31 and 32 are adjacent to the center of the reheating storage 1, It is possible to control the two first heat insulation chambers 31 and 32 as one heat insulation chamber.

  Here, the “warm storage” refers to a food storage having a function capable of maintaining the internal temperature in a certain range, and the “refrigerator” refers to the internal temperature lower than room temperature (for example, 20 ° C.). It shall mean that maintained in the temperature range. In addition, the “reheating chamber” refers to a chamber that can be heated to a high temperature of 120 to 130 ° C.

  The operation panel 5 sets whether to switch the first heat storage 31, 32 to the warm storage, reheating storage, or refrigerator, or sets the temperatures of the first heat storage 31, 32, and the second heat storage 41, 42. The touch panel 5b serving as both a display device and an input device for setting, power on / off, automatic operation on / off, and locking / unlocking of the locking mechanism of the door 8 during reheating are operated. An operation panel 5 provided with operation buttons 5a and the like is provided. In the case of the cook chill type reheating chamber, the temperature inside the first heat insulating chambers 31 and 32 becomes a high temperature of 120 to 130 ° C. during the reheating. Therefore, in order to prevent the door 8 from being inadvertently opened at the time of reheating, a locking mechanism is conventionally provided on the door (not shown).

  In the present embodiment, as shown in FIG. 3, the partition frame 10 includes a frame main body 11 that can hold a plurality of trays 9 arranged in a plurality of rows in the horizontal direction and a plurality of stages in the vertical direction, and a bottom portion of the frame main body 11. It is comprised with the trolley | bogie 12 which can be attached or detached. A heat insulating cover 20 can be attached to the partition frame 10. The heat insulating cover 20 can be attached to the partition frame 10 in a state where the heat insulating cover 20 is pulled out from the storage 2 of the reheating chamber 1, that is, when the heat insulating cover 20 is mounted, the partition frame 10 is attached to the storage 2 of the reheating chamber 1. It is configured so that it cannot be inserted. The heat insulation cover 20 forms a rectangular parallelepiped heat insulation together with the rectangular bottom surface of the partition frame 10.

  As described above, the partition frame 10 is substantially composed of only a metal frame and has no walls. Therefore, when the food is placed on the tray 9 and reheated in the reheating chamber 1, the partition frame 10 is mounted on the partition frame 10. The food on all the trays 9 can be heated almost uniformly. Further, the heat capacity of the partition frame 10 is small, and the energy loss during reheating is small. Furthermore, when pulling out the partition frame 10 from the reheating chamber 1, the possibility that an operator accidentally touches a high temperature part is small and safety is high. In addition, since the heating device 3 and the cooling device 4 are fixed, the probability of failure becomes lower than that mounted on the distribution vehicle.

  The heat insulating cover 20 has two fixed side walls constituting a surface (surface perpendicular to the paper surface) parallel to the first direction in which the trays 9 are horizontally arranged, among four vertical outer peripheral surfaces forming a rectangular parallelepiped heat insulating chamber. 21 and four vertical sides 21a of two fixed side walls that are rotatably connected to each other via a hinge 25, and constitute two surfaces (surfaces parallel to the paper surface) perpendicular to the first horizontal direction. An opening / closing door 22 and a top plate 23 that is attached to the ceiling portion of the partition frame 10 and covers the ceiling portion are provided. Since the open / close door 22 is opened in double doors, when the tray is taken out from the distribution cart, the protruding amount of the open / close door 22 is small and can be arranged through a narrow passage.

  The configuration and material of the heat insulating cover 20 are not particularly limited, but the fixed side wall 21, the opening / closing door 22, and the top plate 23 are individually formed with a heat insulating board or the like, and are attached to the partition frame 10 by hand one by one. You may comprise. In this case, it takes time to attach the heat insulation cover, but the storage space when not in use can be reduced. Alternatively, the fixed side wall 21, the open / close door 22, and the top plate 23 may be formed integrally with a relatively lightweight heat insulating sheet in which, for example, a nonwoven fabric or a resin sheet is laminated, and covered from the upper part of the partition frame 10. Good. In that case, the heat insulating cover 20 can be folded and stored when not in use. Further, a fastener or the like can be used for locking the open / close door 22.

  Next, another specific configuration example of the layout cart according to the present embodiment, that is, the partition frame 10 and the heat insulating cover 20, will be described with reference to FIG. 4, (a) is a configuration of the partition frame 10 in a state where the heat insulating cover 20 is not attached, (b) is a partial configuration of the heat insulating cover 20 disassembled into two, and (c) is the partition frame 10. A state where a part of the heat insulating cover 20 is attached is shown.

  In the configuration example shown in FIG. 4, the partition frame 10 has only a heat insulating wall 10 c provided at the center thereof, and guide flanges 10 d protruding on both sides to support the bottom of the tray 9 on the heat insulating wall 10 c. Is provided. Further, only the frames are provided on both sides of the partition frame 10, and no horizontal guide rails that are engaged with both side walls of the tray 9 are provided. According to such a configuration, although the shape of the tray 9 is limited, the structure of the partition frame 10 can be simplified, the weight can be reduced, and the cost can be reduced.

  In addition, the heat insulating cover 20 can be disassembled into two parts having substantially the same shape, and each part of the heat insulating cover 20 includes one fixed side wall 21 of two fixed side walls and a vertical 2 of the fixed side wall 21. The two doors 22 are rotatably connected to one side 21a via a hinge 25, and the top plate 23a is attached to the ceiling portion of the partition frame 10 and covers substantially half of the ceiling portion. According to such a configuration, since the heat insulating cover 20 is configured by two portions having substantially the same shape, the heat insulating cover 20 can be substantially reduced in weight and can be attached to the partition frame 10. It is relatively easy. Furthermore, two parts can be overlapped when not in use, and the storage space can be reduced. The fixed side wall 21 and the top plate 23a may be fixed, or may be configured to be foldable via a hinge (not shown).

  Next, another specific configuration example of the layout cart according to the present embodiment, that is, the partition frame 10 and the heat insulating cover 20, will be described with reference to FIG. In FIG. 5, (a) shows the configuration of the partition frame 10 in a state where the heat insulating cover 20 is not attached, (b) shows the configuration of a part of the heat insulating cover 20 (heat insulating curtain 20 a), and (c) shows the partition frame 10. A state when the heat insulating curtain 20a is mounted, and (d) shows a state after the heat insulating curtain 20a is mounted on the partition frame 10, respectively.

  In the configuration example shown in FIG. 5, the partition frame 10 has only a heat insulating wall 10 c provided with a guide flange 10 d that is provided at the center of the partition frame 10, and only the frame is provided on both sides of the partition frame 10. And horizontal guide rails engaged with both side walls of the tray 9 are not provided. Further, the partition frame 10 is rotatably connected to four vertical columns 10f provided at the four corners of the bottom surface 10e through hinges 25, and covers four openings that cover the opening for attaching and detaching the tray 9. A door 22 is provided. The hinge on the side of the opening / closing door 22 may be detachable from the hinge of the partition frame 10, and the opening / closing door 22 may be configured to be detachable. Further, the operation handle 13 may be detachable from the partition frame 10.

  The heat insulating cover 20 is a heat insulating curtain 20a urged in a direction wound around the core rod by, for example, a torsion spring, and is partitioned so that the axis of the core rod is parallel to the first direction in which the trays 9 are horizontally arranged. Attached to the ceiling of the frame 10. The frame of the partition frame 10 is provided with a guide member 10g for guiding the heat insulating curtain 20a, whereby the inside of the heat insulating curtain 20a can be prevented from coming into contact with food on the tray 9. . Thus, by making the heat insulation cover 20 into a curtain shape, it is very easy to attach the heat insulation cover 20, and the storage space can be minimized.

  Next, another specific configuration example of the layout cart according to the present embodiment, that is, the partition frame 10 and the heat insulating cover 20, will be described with reference to FIG. In FIG. 6, (a) shows the configuration of the partition frame 10 in a state in which the heat insulating cover 20 is mounted, and (b) and (c) show a state in which the heat insulating cover 20 is folded.

  In the configuration example shown in FIG. 6, the top plate 23 can be valley-folded via a hinge (not shown) at the center in the horizontal second direction orthogonal to the horizontal first direction, and the two fixed side walls 21. Are connected to both sides of the top plate 23 in the horizontal second direction via hinges (not shown) so as to be foldable, and the four open / close doors 22 are respectively connected to the four vertical sides of the two fixed side walls 21. Each side 21a is rotatably connected via a hinge 25. Furthermore, two wheels 24 are provided at the lower ends of the two fixed side walls 21.

  According to such a structure, all the parts which comprise the heat insulation cover 20 are couple | bonded beforehand, and expansion | deployment and folding are possible by what is called one touch. Therefore, attachment to the partition frame 10 is relatively easy, and the storage space when not in use can be made relatively small. Furthermore, since the wheels 24 are provided, the heat insulating cover 20 can be easily handled when the heat insulating cover 20 is taken out of the storage space and stored in the storage space.

  As described above, according to the cook chill system according to the present invention and the serving cart equipped with a heat retention function suitable for the cook chill system, the tray 9 on which food is placed in advance is arranged in the horizontal direction and the vertical direction on the partition frame 10. Thus, since the food to be heated is inserted into the fixed reheating cabinet 1 and heated, the heating on all trays mounted on the partition frame 10 is different from the conventional cook chill system shown in FIG. The food to be cooked can be heated almost uniformly. Moreover, since the partition frame 10 is substantially composed only of a metal frame and has no walls, the heat capacity of the partition frame 10 is smaller than that of the heat insulation, and the energy loss during reheating is small. Furthermore, since the partition frame 10 is pulled out from the reheating cabinet and the thermal insulation cover 20 of the partition frame 10 is attached to constitute a layout cart having a thermal insulation function, when the drawer frame 10 is pulled out from the reheating cabinet, the operator mistakenly The possibility of touching the part is small and the safety is high. Furthermore, since it distributes using the distribution cart provided with the heat retention function comprised by the partition frame 10 and a heat retention cover, the temperature of the cooked food can be kept in the fixed range at the time of the distribution. Moreover, since the heating device 3 (the cooling device 4 as necessary) is fixed, the probability of failure is lower than that mounted on the trolley.

  In addition, this invention is not limited to the structure of the said embodiment, The partition frame 10 does not necessarily need to be able to isolate | separate the frame main-body part 11 and the trolley | bogie 12, and reheats the partition frame 10 with a wheel. The structure inserted in the storage 2 of a store | warehouse | chamber may be sufficient. Further, the reheating chamber 1 and the tray 9 are not limited to the configuration of the above embodiment, and the heated food and the unheated food are placed on different trays, and only the heated food is reheated 1. It may be configured to be reheated at.
