2. Description of the Related Art In the case of cooling high-temperature food products (such as tempura etc.) that are mass-produced one after another without delay, conventionally, FIG.
As shown in FIG. 3, a plurality of cooling units 54 each including a heat exchanger and a blower are provided at a predetermined pitch in a box-type cooling box 53 in which a portion covering the conveyor 51 is used as a cooling path 52. Cool air is blown to the high temperature food introduced from one end one after another, breaking the high temperature boundary layer formed around the food and blowing cold air directly to the skin of the food to cool it efficiently. Thus, the multi-freezer 50 has been developed. In the conventional multi-freezer 50 thus configured, for cleaning the inside, the inspection doors 57 are provided on the side walls 55 and 56 of the cooling compartment 53 at each position where the cooling unit 54 is arranged. 57 was opened, and high-pressure washing water was sprayed from there to various parts to clean the interior. In the figure, reference numeral 58 denotes a pre-cooling unit in which a cooling unit 59 is arranged on the conveyor 51 protruding outside the cooling box.

Further, there is a cooling chamber having a cylindrical shape. In this case, an upper portion surrounded by a vertical line passing through the axis and a horizontal line (that is, in the graph in which the axis is placed at the origin, the first quadrant is shown). ), There is a wall part opened at a predetermined interval and an inspection door is provided there.

Further, in the multi-freezer provided with the box-type refrigerator, the central portion of the inner bottom surface is lowered so that the drainage after cleaning is collected at the center of the bottom portion of the refrigerator.

In these cases, the refrigerator is separately installed and a long pipe is provided from there to the multi-freezer.

[0006]

However, in such an inspection door which is simply provided at each position of the cooling unit, the entire surface of the cooling passage is not opened in any case. There was a problem that some parts were difficult to clean, and some parts were left uncleaned or parts that could not be cleaned sufficiently, making it impossible to clean the whole.

If the drainage after cleaning is collected in the center of the bottom of the cooling box, the debris of foodstuffs will stop in the troughs to hinder the drainage action, and the cleaning of that portion is also limited. There was a problem that it could not be easily done from the inspection door.

If the refrigerator is placed separately, the piping from it will be long and the capacity of the refrigerator or the like will be required in some cases to increase the capacity, or it may be difficult to install it in a narrow space. There was a problem.

The present invention has been made in order to solve the above-mentioned conventional problems, and the purpose thereof is to reach each eye in every cooling unit over the entire length of the cooling box. It can be cleaned cleanly without leaving the conveyor frame, the wall surface inside the refrigerator, etc.
Another object of the present invention is to provide a multi-freezer capable of satisfactorily discharging water without stopping food fragments and the like in the drainage part. Another object of the present invention is to provide a multi-freezer in which piping from the refrigerator is shortened for efficient cooling and easy installation in a narrow space.

[0010]

As a means for achieving the above object, in the multi-freezer according to claim 1 of the present invention, a heat exchanger and a blower are provided in a refrigerating chamber having a cooling passage as a portion covering a conveyor. In a multi-freezer having a plurality of cooling units consisting of and, the cooling box has openings on both side surfaces parallel to the transfer conveyor, the openings being open over the entire length except for the supporting columns, and one end of which is rotatably rotatably supported. The inspection door is configured to open and close the opening.

In the multi-freezer according to a second aspect of the present invention, the bottom surface of the inside of the refrigerator is provided with one side facing the crucible in a single-flow state.

[0014]

1 is a side view showing a multi-freezer 1 according to an embodiment of the present invention, FIG. 2 is a sectional view of the same, and FIG.
FIG. 3 is a plan view of the above. In the figure, reference numeral 2 denotes a cooler, which penetrates the mesh-type transfer conveyor 3 from one end side to the other end side, and the front side (one end side) thereof has a precooling device 4 arranged therein so that it is projected long. In the figure, 5 is a cooling unit for the pre-cooling device, which is composed of a heat exchanger 6 and a blower 7 which are inclined toward the conveyor 3, 8 is a heat exhaustor, and 9 is a cooling unit 5 and a heat exhauster 8 as well. A cooling tunnel 10 for connecting to and is a refrigerator for the entire freezer installed by utilizing an empty portion on the cooling tunnel 9.

The cooling box 2 arranged so as to penetrate the transfer conveyor 3 has openings 11, 11 which are open in parallel with the transfer conveyor 3 on both side surfaces thereof. Is provided with an electric open / close type inspection door 12. The inspection door 12 is formed in a vertically folded shape, and an upper door 13 of the inspection door 12 is fixed to a horizontal shaft 14 axially supported by the cooling box 2. In the figure, 15 is a bearing that rotatably supports a horizontal shaft 14, 16 is a bracket for attaching the upper door 13 to the horizontal shaft 14, 17 is a lower door, and 18 is an upper door 13.
A hinge that rotatably connects the lower side and the upper side of the lower door 17, 19 is an electric motor that drives the horizontal shaft 14, and 20 is a locking device for each door. The electric motor 19 is arranged for each inspection door, and is set so that it can be interlocked or operated independently.

Inside the cooling box 2, a conveyor 3 is provided.
The cooling unit 21 is located above and is displaced in the transport direction.
Are located in two places. In the figure, 22 is a blower for the cooling unit 21, 23 is also a heat exchanger, and 24 is also this heat exchanger 23. Cooled air is blown onto the food on the conveying surface and immediately recovered to generate heat. It is a circulation duct for recirculating after replacement. Since the inside of the cooling compartment is filled with the same cooling air as the inside of the circulation duct, the entire length inside the cooling compartment serves as the cooling passage 25.

The cooler 2 also has a one-sided inner bottom surface 26 with one side being the upper position and the other side being the lower position.

In the multi-freezer 1, high temperature food such as tempura is supplied onto the conveyor 3 from a device (not shown). Then, it first passes through the cooling tunnel 9 and is pre-cooled by the cooling unit 5. In this case, the cooled air is only discharged without being circulated.

Next, the precooled high-temperature food is carried into the cooling box 2 and cooled by the cold air in the box, and at the same time, the cold air is blown below the two circulation ducts 24, and the high-temperature boundary layer. The food is rapidly cooled by destroying the water and applying cold air directly to the skin of the food.

In such a multi-freezer, water vapor or vapor of fats and oils attach to each part, and when there are times when the temperature becomes low, etc., floating bacteria easily attach to them. For this reason, cleaning is an essential task. In the cleaning work, first, the lock device 20 of each door is released, and then the horizontal shaft 14 is driven by the electric motor 19. When the horizontal shaft 14 is rotated in the direction in which the upper door 13 is flipped up, the lower door 17 is lifted up while hanging down from the lower side of the upper door 13, and eventually the upper door 13 and the lower door 17 are separated from each other. It is folded in two and stands upright above the horizontal shaft 14.

For this reason, the cooling compartment 2 is opened on the entire side, and the two internal cooling units 21, 21 are
The transfer conveyor 3, the interior ceiling, the inner bottom surface 26, and the like are all in a state where they can be visually confirmed through the openings 11, 11. In this state, high-pressure washing water can be sprayed to wash each assembly. Further, the sewage that is being washed drips onto the inner bottom surface 26, and along with the pieces of the food that have fallen off, one side of the refrigerator 2 is washed down on the crocodile.

As described above, in the present multi-freezer 1, since both sides can be opened at all sides, the inside can be confirmed in every corner, and the inside can be cleaned cleanly without leaving the inside. You can The inspection door folds in half and stands up, so the center of gravity is low and there is no force on each part. Further, since it can be opened and closed if there is a lateral space substantially the same as the vertical width of the upper door 13, it can be used in a narrow place. The sewage that is being cleaned flows out toward the outside of the cooling box 2 due to a one-way flow, and the food pieces and the like that have fallen off during cleaning flow to one side, so that the inner bottom surface can also be cleanly cleaned. Since the refrigerator 10 is integrally provided by utilizing the empty portion on the conveyer conveyor 3, the piping from the refrigerator to the cooling unit only needs to be in-machine piping, which improves the cohesion and reduces the resistance of the refrigerant flow passage to reduce its capacity. Even if it is small, the heat exchange with each heat exchanger can be performed efficiently. In addition, because a separate place for the refrigerator is not required,
It can be easily installed in a narrow space.

Next, another embodiment of the invention will be described with reference to FIGS. FIG. 4 is a side view showing the multi-freezer 30 for increasing the working capacity, and FIG. 5 is a sectional view of the same. In the multi-freezer 30 in this case, four sets of cooling units 21 are sequentially arranged in the transport direction, and the blower 22
Is supported by an arm 31 axially supported by the cooling cabinet 2 so as to be drawn out of the refrigerator. Further, in this case, since the refrigerator 2 is long, the inspection doors 12 are provided on both sides of the central support portion 32 as a boundary, and are individually set to be opened and closed. Other than this, the configuration is the same as that of the multi-freezer 1, and therefore, the same components are designated by the same reference numerals and the description thereof is omitted.

In the present multi-freezer 30, the blower 22 to which dirt easily adheres is pulled out to the outside of the refrigerator to further facilitate cleaning, and since it can be carried out in a comfortable posture, it has an effect of improving safety.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the invention. However, it is included in the present invention.

Although the inspection door 12 has a two-part structure, the shape of the inspection door can be arbitrarily set. For example, the inspection door may be a single type or may be a slide type that slides upward. .

The shape of the cooling unit 21 and the number of installed units,
The installation position and the like can be set arbitrarily.

The inspection door 12 may be opened / closed by an electric type, a hydraulic type or a pneumatic type, or a reduction gear connected to a horizontal shaft may be manually driven. An interlock may be provided between the inspection door 12 and the electric motor 19 for safety.

A facility for spraying cleaning water may be provided in the refrigerator.

[0030]

As described above, the present invention claims 1.
Since the multi-freezer described above has the above-mentioned structure, when the inspection door is opened, the opening over the entire length of the cooling box appears on both sides.Thus, the entire interior can be seen through the opening, and every corner is touched. The effect is that it can be cleaned neatly without leaving any details.

In the multi-freezer according to the second aspect of the present invention, because of the above configuration, the sewage that is being washed during cleaning drips to the inner bottom surface and is sprinkled on one side of the cooler together with the pieces of food that have fallen together. Therefore, it is possible to obtain an effect that it can be cleaned without being left on the central bottom surface of the refrigerator.

In the multi-freezer according to the third aspect of the present invention, since the inspection door is rotated and flipped up, a wide side space corresponding to the height of the inspection door is not required, and the inspection door is flipped up. Since the position of the center of gravity becomes low, stability is improved, and each part is not overly forceful and safe, and it can be installed in a place with a low ceiling.

Since the multi-freezer according to the fourth aspect has the above-mentioned structure, it is possible to efficiently cool the multi-freezer by eliminating extra piping, and to install a refrigerator in a narrow space without an extra space. The effect that it becomes possible is obtained.
