Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a thawing machine that efficiently heats a large number of frozen foods and other foods to be heated using a hot water bath.

<Conventional technology> Generally, when heating a large amount of food such as frozen food in a hot water bath, a large number of food items are placed in boiling water in a large pot and heated by stirring in the boiling water. was being carried out.

<Problems to be solved by the invention> However, in the above-mentioned heating process for heated foods, when a large number of heated foods are added at the same time, the temperature of the boiling water drops rapidly, making it difficult to properly defrost the food. There was a problem that it became impossible to perform proper heating.

For this reason, Japanese Patent Publication No. 48-31914 discloses a heating tank having two pipes for liquid, one for outward and one for return, a processing container to which these pipes are connected, and a heating tank that is substantially completely a heating fluid which fills the processing vessel and at least partially fills the processing vessel; an auxiliary bottom having a partition flange within the processing vessel and substantially preventing short-circuit circulation of flow between the two pipes, said auxiliary bottom; An apparatus for reconstituting frozen foods has been proposed, characterized in that the apparatus has an opening spaced from the side wall of the processing vessel.

This device uses a partition flange to prevent short-circuit circulation between the two pipes, and also uses an auxiliary bottom to deflect the heated fluid flowing into the processing container from the outgoing pipe to the side, and opens an opening around the auxiliary bottom. It is configured to be more dispersed and advanced to the upper part of the processing container, thereby realizing automatic circulation flow within the processing container to the return pipe.

However, even in this device, when a large number of frozen foods are placed into the processing container at the same time, the circulating heated fluid stream comes into contact with a large number of heated foods almost at the same time, so the temperature of the heated fluid decreases rapidly. At the same time, there was a problem that a temperature difference occurred between the upstream and downstream sides of the circulating flow, making it impossible to properly heat and defrost the product. In addition, this equipment consists of two tanks, a heating tank and a processing container, and both are used for the outbound and return trips.
The structure was complicated because the two pipes connected each other, and the heating tank was closed, making it difficult to clean.

This invention was made in order to solve the above-mentioned problems, and its purpose is to provide a thawing machine that can efficiently heat a large number of foods to be heated in a hot water bath.

<Means for solving the problem> This invention was made to achieve the above object, and the bottom inner tank and the upper opening formed in the center of the bottom so as to protrude downward are continuous with the bottom inner tank opening. and a bottom outer tank formed to protrude downward so as to surround the bottom inner tank across the flue part, and the bottom inner tank and the bottom outer tank are connected by a communicating pipe at the lower part of each.

A thawing machine is provided with a plurality of partition cylinders, and is formed so that a food to be heated is put into the partition cylinder and the food to be heated is heated by the jet stream.

<Function> This device is constructed as described above, and the hot water and air bubbles that are heated and rise in the hot water tank are captured by the partition plate, converged in a substantially conical part, and jetted upward from the spout hole. do.

The jet stream is guided to the partition tube, and
It comes into intensive contact with the heated food placed in the partition tube, transfers heat, and rises further.

Then, the jet stream that has been deprived of heat by heating the food to be heated is surrounded by the partition tube and does not overflow into the hot water tank, but instead overflows from the top of the partition tube to the top of the lid and is discharged. The appropriate heating temperature is maintained by the entry of the jet stream.

In addition, the combustion chamber and flue part maintain a large heat exchange area by being in contact with the bottom surface and side walls of the bottom inner tank and bottom outer tank of the hot water tank, and the communication pipe itself is also heated.

<Example> An example of this invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view showing the structure of the defrosting machine of this invention, and FIG. 2 is a plan view.

In the figure, 1 is a thawing machine, and the thawing machine 1 includes a hot water tank 2 whose upper part is covered with a lid part 7, a combustion chamber 16 that heats the hot water tank 2, and a flow of hot water and bubbles that are heated and rise upward. a partition plate 25 having a plurality of substantially conical portions 26 that are capable of ejecting water;
It is configured to include a plurality of partition tubes 30 each of which is provided so as to be able to guide the ejected flow from each substantially conical portion 26 upward.

Note that the substantially conical portion herein refers to a cylindrical portion that tapers at the end, such as a conical shape or a pyramid shape.

In the embodiment, the hot water tank 2 has a rectangular outer shape, and its upper part is covered with a lid part 7. This lid portion 7 has a plurality of lid holes 8 (nine holes in the embodiment) into which partition tubes 30, which will be described later, can be respectively fitted.

At the center of the bottom of the hot water tank 2, there is formed a bottom inner tank 3 which has a planar circular shape and projects downward.On the outer periphery of the bottom inner tank 3, a bottom inner tank 3 is formed which extends downward so as to surround the bottom inner tank 3 with a flue section 4 in between. A bottom outer tank 5 having a protruding planar square shape is formed. The lower part of the bottom outer tank 5 and the lower part of the bottom inner tank 3 are communicated with each other by a plurality of communication pipes 6. Further, a water supply tank 11 is connected to the bottom outer tank 5 via a water supply pipe 14, and the water supply tank 11 is equipped with a water supply port 12 and a ball tap 13 to supply insufficient water to maintain the hot water level at a predetermined level. It is formed to hold H. Furthermore, a gutter-like top plate 9 is provided on the upper outer periphery of the hot water tank 2 to receive overflowing hot water from the lid 7, and a conduit 37 for discharging the overflowing hot water is provided on the top plate 9. . Further, a heat insulating wall 10 is provided below the top plate 9 so as to surround the sides and bottom of the hot water tank 2 and to form a flue 19 between the hot water tank 2 and the hot water tank 2. Note that an exhaust pipe 20 for exhaust is provided at a predetermined position of the heat insulating wall 10.

A stepped cylindrical combustion tube 15 is arranged in the flue portion 4 and surrounds the bottom inner tank 3 at a predetermined interval. This combustion tube 15 is made of zirconia ceramics that can emit far infrared rays when heated, and forms a combustion chamber 16 between it and the bottom surface of the bottom inner tank 3. An inner flue 17 is formed between the combustion tube 15 and the bottom inner tank 3, and an outer flue 18 continuous to the inner flue 17 is formed between the combustion tube 15 and the bottom outer tank 5. The external flue 18 is communicated with a flue 19.

In the embodiment, the partition plate 25 has nine substantially conical portions 26 that project upward in a conical shape, and each conical portion 26 has an ejection hole 27 at its top. The partition plate 25 is horizontally arranged at a predetermined position in the bathtub 2 with its outer peripheral edge bent downward and at a predetermined distance from the inner wall of the bathtub 2 .

In the embodiment, the partition tube 30 is formed into a cylindrical shape, and a flange-like edge portion 31 is provided at the upper end thereof. This partition tube 30 is fitted into each lid hole 8 of the lid part 7, so that its end edge 31 abuts the upper surface of the lid part 7, and its lower end touches the substantially conical part 2 of the partition plate 25.
It is formed so that it is located directly above the bottom of the In addition, numeral 33 is a thawing basket with a handle, which is formed so that heated food can be put therein, and which is also formed so that it can be taken in and out of the partition tube 30 . Furthermore, a drainage conduit 35 having a drainage valve 36 is provided at the bottom of the bottom outer tank 5 .

On the other hand, the combustion chamber 16 includes a secondary air induction type main burner 40 and a pilot burner 41,
A fire protection sensor 42 is provided, which is connected to a gas supply pipe 47 via a gas main stock 45 and a pilot stock 46, respectively. Note that 43 is a spark igniter for igniting the pilot burner 41.

Next, the operation of the thus configured decompressor will be explained.

When the main burner 40 of the combustion chamber 16 is ignited, its flame heats the bottom surface of the bottom inner tank 3. Furthermore, the generated high-temperature combustion gas passes through the inner flue 17, the outer flue 18, and the flue 19, and is discharged from the exhaust stack 20 while gradually lowering its temperature.

At this time, a wide heating area is obtained from the bottom surface of the bottom inner tank 3 to the side wall, and from the inner wall of the bottom outer tank 5 to the bottom surface and the outer wall. In addition, the combustion tube 15 is heated to a high temperature and emits far infrared rays from its inner and outer walls, and the far infrared radiant heat is superimposed on the heat of the high temperature combustion gas and causes the bottom inner tank 3 and the bottom outer tank 5 to be heated. Heat.

On the other hand, the hot water heated in the bottom inner tank 3 and the bottom outer tank 5 rises with many generated steam bubbles. This upward flow is captured by the partition plate 25,
Furthermore, it is focused by each substantially conical portion 26 and is ejected upward from the ejection hole 27 .

The jet stream ejected from the jet hole 27 flows through the partition tube 30.
Guided by the air, the liquid is regulated from dispersing laterally and ejected upward. This ejected flow intensively contacts the food to be heated that has entered the thawing basket 33 placed in the partition tube 30 and transfers heat thereto, and also performs an agitating action due to the group of air bubbles. The ejected flow, which has been deprived of heat, is guided by the partition tube 30 and squirts upward.
0 overflows onto the lid part 7, passes through the top plate 9, and is discharged from the conduit 37. Therefore, the hot water whose temperature has been lowered by heating the food to be heated does not overflow onto the hot water surface H. In addition, the hot water at the top of the hot water tank 2 in contact with the outer periphery of the partition tube 30 lowers its temperature slightly and descends, passing through the bottom outer tank 5 and the communication pipe 6 to the bottom inner tank 2.
It circulates, reheats, and rises. Therefore,
A drop in temperature of the entire hot water in the hot water tank 2 is prevented.

Furthermore, a subsequent jet flow is ejected into the partition tubes 30, and the inside of each partition tube 30 is maintained at an appropriate heating temperature. As a result, the foods to be heated are simultaneously put into each of the partition tubes 30 and thawed, etc., and a large quantity of food is efficiently heated.

Note that this invention is not limited to the above-mentioned explanation and illustrations, and the embodiments thereof can be changed without departing from the technical idea of this invention. For example, the substantially conical portion 26 may be formed in the shape of a pyramid, and even if the partition tube 30 is formed in the shape of a rectangular tube, similar effects can be achieved.

Moreover, this thawing machine 1 is not limited to application only to thawing frozen foods, but can of course be applied to boiling pasta etc. as long as the food to be heated is heated in a hot water bath. It is.

<Effects of the invention> As explained above, the thawing machine of this invention includes a partition plate having a plurality of substantially conical parts that converge hot water and bubbles and jets them upward, and a partition plate that has a plurality of substantially conical parts that converge hot water and air bubbles and spray them upward. A partition tube is provided to guide the flow upward,
The structure is configured so that the food to be heated is heated by contact with the food to be heated by the jet stream inside the partition tube, and the jet stream, which has been stripped of heat, overflows onto the lid through the partition tube, which reduces the temperature of the entire hot water in the hot water tank. In addition to preventing this, the inside of the partition cylinder can be maintained at an appropriate heating temperature by the subsequent jet flow.

Therefore, the food to be heated can be simultaneously put into each partition cylinder to perform heating operations such as defrosting a large quantity in a short time, and the hot water in the hot water tank can be automatically renewed by the overflow of the jet stream. be able to. In addition, by equipping an automatic water supply device with a ball tap, etc., we can replenish the amount of overflow water and maintain the hot water level.
The cleaning properties of hot water can be maintained.

Furthermore, since an inner bottom tank and an outer bottom tank are formed at the bottom of the bathtub, and inner and outer flues are provided between them for heating, a large heat exchange area can be obtained, and high thermal efficiency can be obtained. In addition, the exhaust temperature drops to 230-280℃ compared to the 350-400℃ of conventional products, making it easier to treat the exhaust and making the hot water tank simpler and easier to clean. It has effects such as obtaining.
