Description

[Detailed description of the invention] (a) Industrial application field The present invention applies to foods that require heat treatment.
This invention relates to steam kitchen, which is subjected to heat treatment using steam heat.

(b) Prior Art As shown in FIG. 3, a conventional steam kitchen is equipped with a heating chamber 100 made of a metal plate or other heat-resistant material, a door 200 made of the same material that can be opened and closed at the side entrance, and a door 200 made of the same material at the side entrance. This has an extremely simple structure that includes a steam injection pipe 300 for injecting steam supplied from the outside into the heating chamber, and the object to be heated 400 is placed on a cart 500 as shown in the figure. It was to be carried in and out together with the trolley 500 through the side entrance.

(c) Problems to be Solved by the Invention In the steam kitchen having the above-described structure, the door on the side of the heating chamber is opened and closed each time an object to be heated is brought in and taken out, so a large amount of internal heat flows out to the outside each time. ,
In order to raise the temperature to the target value again, it is necessary to inject a new large amount of steam and to increase the time required for the temperature to reach the target value, and these two elements, energy and time, are important for all modern industries. Commonly, this is the biggest factor leading to increased product costs, and there is a risk that it may have a negative impact on the quality of processed products.

The present invention has been devised to solve the above problems.

(d) Means to solve the problem The problem mentioned above is that there is a heating chamber that is open at the bottom and has a steam injection pipe, a heater for drying the surface of the object to be heated, and an automatic temperature control device inside, and the lower part of the heating chamber. There is an elevator room with a built-in elevator equipped with a saucer to which a drain discharge pipe is connected, and further below the elevator room there is a steamer that obtains water from a removable water tank and supplies steam to the steam injection pipe. This problem is solved by a steam kitchen characterized in that a steam generating chamber and a steam generating chamber to which a discharge part of the drain discharge pipe is attached are connected to each other.

(e) Examples Examples of the present invention will be described below based on the drawings. FIGS. 1 and 2 are cross-sectional views of a steam kitchen according to an embodiment of the present invention. In the figures, the steam kitchen 1 is roughly located at the upper part and is located between the heating chamber 2 which is open at the bottom. The elevator room 3 is made up of three parts: an elevator room 3 and a steam generation room 4 located at the bottom, and each part will be described in detail below. The heating chamber 2 has a glass window 5 and a temperature sensor 6a of an automatic temperature controller 6 on the side so that the inside can be visually observed from the outside, and a steam injection pipe 7 is located directly below or near the lower front opening side edge. An elevator 1 for moving objects to be heated, in which a heater 8 for drying the surface of the object to be heated is mounted, and the elevator chamber 3 is equipped with a drain tray 10 having a slideable internal drain pipe 9 attached to the bottom part.
1 is built in, and a drain guide plate 12 is attached to the inner periphery of the upper part for guiding the drain that is about to fall downward along the inner wall to the drain receiving tray 10. The steam generation chamber 4 has a steam generation heater 13 at the bottom, a removable water supply tank 14 that supplies water to the steam generation heater 13, and a drain that receives the drain discharge inner pipe 9 and discharges the drain to the outside. The elevator room 3 has an outer discharge pipe 15, and is further provided with a doorless loading/unloading port 16 on one side of the elevator room 3 for loading and unloading objects to be heated. In addition, in the figure, in order to improve work efficiency, a heating object mounting table is used which has a folding storage wheel 17 and a rod section 19 for placing a heating object 18 such as ham or sausage. Although a dedicated trolley 20 and a trolley sliding table 21 are shown, it is needless to say that there is no need to use a dedicated trolley, and the drive mechanism for the heated object moving elevator 11 may be of any existing type. Available for use.

(f) Action In FIGS. 1 and 2, the trolley 20 on which the object to be heated 18 is mounted is slid on the table 21, carried in through the loading/unloading port 16, and placed in a fixed position above the elevator 11 in the elevator room 3. Place it. Thereafter, the heating object moving elevator 11 is raised to a predetermined position, and the heating object 18 is steam-heated in the heating chamber 2 at a predetermined temperature for a predetermined time. After being heated for a certain period of time, the heated object 18 whose finish has been visually confirmed through the window glass 5 is carried out in the reverse order of the carrying-in procedure. Here, the steam injected from the steam injection pipe 7 is generated by heating water supplied from a removable water supply tank 14 built in the steam generation chamber 4 with a steam generation heater 13. The temperature in the heating chamber is detected by a temperature sensor 6a, and the automatic temperature regulator 6 changes the amount of steam injection to ensure a predetermined temperature. On the other hand, the drain formed by condensation of steam in the heating chamber 2 is removed from the drain guide plate 12.
The water is collected in the drain tray 10 and discharged to the outside of the steam kitchen 1 through the drain discharge inner pipe 9 and the drain discharge outer pipe 15.
Further, the water vapor adsorbed or condensed on the surface of the heating object 18 is heated and dried as necessary by the heater 8 for drying the surface of the heating object.

(g) Effects of the invention However, according to the present invention, since the object to be heated is transferred into and out of the heating chamber from the open lower part, the heat inside the heating chamber that flows out at that time is small, and new heat is supplied. Since only a short amount of time is required for the steam and temperature recovery, it is possible to secure higher processing capacity than conventional steam kitchens, and also to finish the heated object to a stable quality.

In addition, the drain tray attached to the elevator for moving objects to be heated serves as the bottom cover of the heating chamber, eliminating the need for a door at the loading/unloading exit on the side of the elevator chamber. Steam is obtained from a built-in steam generator, and water is supplied to the steam generator by a removable water tank. Drainage, which was not previously considered, is now collected from the drain pipe. Since the waste can be discharged and received in a simple container, it has become possible to carry out new installations and relocations without the need for special construction.

As described above, the present invention can solve all the problems that conventional steam kitchens had, and can exhibit excellent effects on energy efficiency, work efficiency, and quality of objects to be heated. This is extremely useful for realizing a steam kitchen that is almost free from external restrictions in installation and operation.
