An air curtain device 83, etc., installed near the upper part of the inside of the refrigerator always keeps the temperature in a hygienic manner (specifically, +
(About 3 ° C). In addition, when at least one of the 14 cool wagons 11 has a temperature rise of + 5 ° C. or more, an alarm device (a lamp, a buzzer, or the like) in the driver's seat can be operated. In addition, a lightweight, vertically movable (manually operable in case of failure) rotary tailgate lifter device 85 is provided at the rear lower part of the refrigerated freezer for facilitating carry-out and carry-in of the cool wagon. Will be equipped.

As described above, the main devices (11, 41, 71, 81, etc.) constituting the system of this embodiment have been individually described. About the point, I explain briefly.

Out-of-hospital feeding system In the out-of-hospital kitchen (communal kitchen), various dishes are prepared according to orders from a plurality of hospitals, and cooked in them (heated to about 70 degrees for sterilization). Then, a treatment of cooling to about + 3 ° C. is performed within about 90 minutes, and thereafter (or before that), a so-called skin pack is performed together with the tableware. These cooked foods (cooks) are efficiently stored in the cool wagon 11, and the stored cool wagon 11 is mounted on the above-mentioned refrigerator-freezer 81 and delivered to a target hospital (delivery destination). Is done.

On the hospital side, the delivered cool wagon 11 is connected to a cooling unit 71 (71 '), and by the cooling unit 71 supplying cold air,
The food in the cool wagon 11 is kept refrigerated (+ 3 ° C
Degree). Prey (patient) before serving food
Are transferred from the cool wagon 11 to the hot wagon 41 according to the food type breakdown table (menu) corresponding to. At this time, dishes for one person are arranged in a predetermined arrangement on each tray 51, and they are stored in predetermined compartments of the hot wagon 41, respectively.

The heating of the food by the far-infrared heater 61 is started individually (or simultaneously) at a predetermined heating start time by a timer device (control device 65) of the hot wagon 41, and after a predetermined time elapses (for example, 30 to 40 minutes). (When the desired temperature is reached), each dish is kept warm and at a predetermined temperature. That is, with such a series of operations, for example, "rice" is around 50 ° C and "main dish" is 60
Heated and kept warm at ~ 65 ° C. Some dishes are not heated or kept warm. In addition, hot wagon 41
The internal fan operates during heating and keeping the temperature inside, but in some cases, the hot wagon 41 is cooled by the cooling unit 71.
, And the temperature rise of the tray 51 and the dishes themselves may be further suppressed by blowing cool air from the cooling unit 71.

The hot wagon 41, which is ready or in the middle of it, is transported in advance or immediately before to the vicinity of the hospital room,
While waiting, the setting status of the hot wagon 41 differs depending on the arrangement and structure of the hospital room. That is, for example, as shown in FIGS. 26 and 27, when the hospital rooms are arranged on one side of the passage (both figures (A)), the two hot wagons 41 are arranged side by side in the same direction, and are narrow. If hospital rooms are lined up on both sides of the corridor (both figures (B)), 2
When the hot wagons 41 of the stand are arranged side by side in the opposite direction and the patient rooms are lined up on both sides of the wide passage (both figures (C)),
It is conceivable to arrange two hot wagons 41 back to back. Of course, it does not matter if the individual hot wagons are set individually.

By the way, if the tableware after eating and drinking is kept at room temperature as it is, it emits an unpleasant odor, so it is first stored in the hot wagon 41 and connected to the cooling unit 71 for refrigeration / storage, or It is conceivable to transfer the hot wagon 41 to the cool wagon 11 once and then connect it to the cooling unit 71 for refrigeration and storage. The tableware thus refrigerated and stored in the cool wagon or the like is collected by the refrigerated freezer 81 in the out-of-hospital kitchen while being stored in the cool wagon 11.
