Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial field of application The present invention provides steam blowout during heat sterilization with steam after cleaning of food transport tanks or when steaming foods or raw materials thereof. The present invention relates to a steam supply device that connects a steam pipe to a steam inlet provided at the bottom of a case of a steamer or a steamer and blows steam into the case. It is not limited to food transport tanks and steamers, but also applies to anything that blows steam into the case through a steam pipe that can be detached from the bottom of the case.

Conventional technology For example, tanks for transporting liquid foods such as transport tanks for cooking oil, oil, soy sauce, vinegar, jam, mayonnaise, etc., must be cleaned after transporting and before being filled with new foods and heat sterilization with steam. . Therefore, the tank has a steam inlet at the bottom. Usually, this steam inlet also serves as an outlet for liquid food. The leading end of the steam pipe connected to the steam source is connected to the outlet (steam inlet) by fitting means, and is blown out into the steam tank for heat sterilization.

Also, in the case of a steamer, place steamed items such as food and its raw materials inside the case on a stand partitioned by wire mesh etc., and connect steam piping to the steam inlet formed on the bottom to inject steam. , It is steamed with the steam.

Conventionally, these steam pipes and steam inlets are connected to each other by tightly connecting pipes having the same diameter so that steam does not leak.

Problems to be Solved by the Invention In any case, there is no particular problem regarding heat sterilization and steaming, but there was a problem when removing the steam pipe.
Since the steam inlet is at the bottom of the case, the condensed steam that has been blown into the case falls and accumulates in the connecting portion. The temperature of this condensate is as high as 80 to 90 ° C.
After sterilization etc., the steam pipe must be removed,
At that time, the high-temperature condensate collected in the connecting portion may scatter, and may cause an operator to get burned. Therefore, in the case of the conventional device, the work of removing the steam pipe was very dangerous.

When steaming, the steam must be blown from below,
In addition, since an outlet for taking out a product such as a transportation tank must be formed at the bottom, vapor inflow must be made from the bottom, and the above-mentioned danger has been unavoidable in the past.

The present invention has been made for the purpose of avoiding such a danger.

[Configuration of the Invention] Means for Solving the Problems In the present invention, the outer diameter of the tip of the steam pipe is set to be smaller than the inner diameter of a steam inlet and a fitting means for connecting the steam inlet and the steam pipe. A gap is formed between the outer periphery of the steam generator and the inner periphery of each of the steam inlet and the fitting means to allow the condensed liquid of the steam to escape to the outside.

Action As described above, when a gap for releasing the liquid is formed between the steam inlet and the inner circumference of the fitting means and the outer circumference of the tip of the steam pipe,
The condensed liquid in the case travels down the wall and drops to the joint between the steam pipe and the steam inlet, but naturally drops outside through the gap formed in the steam inlet. As a result, the condensate does not accumulate at the connection between the steam inlet and the steam pipe. Therefore, the hot condensate does not scatter when the steam pipe is removed, and the removal work can be made safe. The steam pipe has its tip inserted inside from the steam inlet and blows out at a considerable pressure, so steam does not directly leak to the outside, and even if it leaks a little, there is no obstacle to heat sterilization or steaming. Nor.

Example FIG. 1 relates to a edible oil transportation tank, in which a tank 1 as a case is fixed to a carriage 3 having wheels 2 and 2 by a support 4. In this tank 1, the lower end portion of a cylinder whose upper end is open is narrowed down, the central portion is made into a thin tubular shape and bent laterally, and the tube is used as an outlet 5. The upper end of the tank 1 is covered with a lid 6.

Normally, the tip of the outlet 5 is closed, the lid 6 is removed, the tank 1 is filled with edible oil, the lid 6 is covered, the cart 3 is carried as it is, and the edible oil is taken out from the outlet 5 at the destination.

After that, clean the tank before filling new cooking oil,
Heat sterilize. During the heat sterilization, a steam source (not shown)
The tip of the steam pipe 7 connected to the tank 1 is connected to the outlet 5 of the tank 1. In this embodiment, the tip 8 of the steam pipe 7 is made thinner than the inner diameter of the outlet 5 (hereinafter referred to as the steam inlet). Therefore, the tip portion 8 is inserted even inside the steam inflow port 5. The steam pipe 7 is attached to the steam inlet 5 by a union fitting type fitting means 9 as shown in FIG.

The fitting means 9 is provided with a male screw portion 10 on the outer periphery of the tip of the steam inlet 5, and a joint 11 having a female screw to be screwed to the male screw portion 10 is attached to the tip of the steam pipe 7. . The steam pipe 7 and the joint 11 are connected by a support arm 12. This is seen from the steam pipe 7 side is the third
In the figure, the hole 13 at the center of the joint 11 is made larger than the outer diameter of the steam pipe 7, and a gap is formed between the steam pipe 7 and the steam inlet 5. In the present embodiment, the tip portion 8 of the steam pipe 7 is made thinner than the steam pipe itself, but depending on the thickness of the steam pipe 7 itself, it may be directly inserted into the steam inlet 5. In this way, the joint 11
The diameter of the hole 13 at the center of is increased and the joint 11 and the steam pipe 7 are connected by the support arm 12 between the steam inlet 5 and the inner circumference of the joint 11 and the outer circumference of the steam pipe 7. It goes without saying that this is to form a gap.

Thus, in this embodiment, since a gap is formed in the connecting portion of the steam inlet 5 with the steam pipe 7 (hereinafter also simply referred to as an outlet), the condensed steam of the steam blown out from the tip 8 of the steam pipe 7 is After flowing down along the wall, it does not fall further through the gap at the outlet of the steam inflow port 5 and stays in the connecting portion by the fitting means 9. Therefore, there is no risk of high temperature water splashing during the work of removing the steam pipe 7 later, and the work can be performed safely.

FIGS. 4 and 5 show another example of the fitting means 20, in which the outlet 21 of the steam inlet 5 is expanded in a conical shape, and a flange 22 is attached to the tip thereof, and a similar flange 23 is also attached to the steam pipe 7. Is attached by a support arm 24, the flanges are abutted against each other, and the periphery thereof is tightened by a ferrule band 25.

It will be understood that the action is not particularly different from that described above. Further, in the case of using the ferrule band 25, the band can be tightened with one touch, so that the steam inlet 5 and the steam pipe 7 can be easily connected.

Fig. 6 shows an example of application to a steamer, and its case 31
Bottom 32 is inclined so as to descend toward the steam inlet 33, the inside is appropriately partitioned by a metal net 35, and what is steamed is placed on the metal net 35. This steam inlet 33
Further, the steam pipe 34 is connected by the fitting means having a gap at the outlet shown in FIGS. The action of forming the gap is not different from the above-mentioned example.

EFFECTS OF THE INVENTION As described above, according to the present invention, the outer shape of the tip of the steam pipe is smaller than the inner diameters of the steam inlet and the fitting means, and the outer circumference of the steam piping and the inner circumference of each of the steam inlet and the fitting means. Since a gap is formed between the and to escape the condensed liquid of the vapor to the outside, the high temperature water that has been blown into the case, condensed and dropped falls out through the gap at the outlet of the steam inlet, It does not accumulate at the connection between the steam inlet and steam piping.
Therefore, the risk of work is eliminated, and the work for removing the steam pipe can be performed with confidence.

Further, according to the present invention, since a gap is formed at the outlet of the steam inlet for blowing out steam, the pressure in the case does not become unnecessarily high, and the lid covering the case does not come off due to the pressure. .
