Description

[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is a small fish simmering device that utilizes the phenomenon that when small fish such as shirasu, a raw material for boiled tsukudani, and small girls rise when they are cooked.

[0002]

2. Description of the Related Art A conventional apparatus for boiling small fish such as shirasu is shown in FIG.
As shown in Fig. 1, a steam heater 2 with a steam pipe 3 is provided at the bottom, and a boiling pot 1 having a water injection pipe 12 at the top is used. In the boiling pot 1, small fish 5 such as shirasu are put. , I picked up only the boiled small fish 5'which had been boiled and matured by the scooping colander 13.

In recent years, a simmering device for small fish such as shirasu has been developed, and as shown in FIGS. 4 and 5, the steam pipe 3 is provided on the bottom side.
Is equipped with a steam heater 2 and has an inlet 15 for injecting shirasu together with water in the center, and an outlet 1 at the outer peripheral end.
An automatic simmering device for exclusive use of shirasu is used, in which a fluid-cooking vessel 14 in the form of a spiral gutter connected to a conveyer 10 is used. In this fluidized boiling pot 14, the water that flows with the shirasu 5 that has entered from the inlet 15 is heated to become hot water,
It is cooked at the time when it reaches the delivery port 16.

[0004]

[Problems to be Solved by the Invention] The conventional simmering device using a scooping colander has been used for a long time except for the steam heater, requires a great deal of manpower, and scooping from inside hot water is not possible. Since it requires skill and there is a risk of burns, there were many problems in work.

[0005] In addition, in the simmering device using a fluidized boiling pot, the size of the fish body of Shirasu varies. Therefore, uncooked or overcooked liquor occurs during the flow from the inlet to the outlet, and the fish body collapses due to overcooking. Therefore, there is a problem that the quality of the product deteriorates.

[0006]

[Means for Solving the Problems] In order to solve the conventional problems, the phenomenon in which boiled small fish floats up is effectively utilized, and from the circulation pouring pipe side to the circulation drainage pipe side of the small fish sending side. The boiled boiled small fish that floated on the flowing water of hot water is placed and moved, and only the boiled boiled small fish flowing over the perforated partition plate is sent out and sent to the conveyor. Therefore, since small fish that are not boiled or over-cooked are not sent out from the boiling pot and mixed, the quality can be made uniform and the quality and work efficiency can be improved even if the size of the fish is small or large.

[0007]

[Operation] Since the water in the boiling pot is turned into hot water by the steam heater, the small fish such as shirasu and the like are boiled and matured. Boiled small fish have a phenomenon of rising, so the boiling water in the upper layer of the boiling pot flowing from the circulating pouring pipe side to the circulating drainage pipe side, which is the sending side of boiled small fish, is boiled and rises. Only the small fish are placed on the water flow, passed over the perforated partition plate to the delivery side in the direction of the circulating hot water pipe, and placed on the delivery conveyor. Therefore, small fish such as shirasu placed in the boiling pot is boiled while moving at the bottom and middle layer of the boiling pot until it is boiled, and after boiling, it floats up and rides on the upper stream and is boiled and boiled. Since they are sent out in order, the quality of the product is uniformed by preventing the mixing of uncooked or overcooked small fish.

[0008] Further, the hot water in which small fish such as shirasu or the like flows is circulated by circulating from the circulation drainage pipe to the circulation pouring pipe, so that the heat energy can be effectively used.

[0009]

EXAMPLE One example shown in FIGS. 1 and 2 will be described. Reference numeral 1 is a boiling pot, which is provided with a steam heater 2 composed of a steam pipe 3 at the bottom. The hot water 4 in the boiling pot 1 is discharged from the circulating hot water discharge pipe 6 by connecting the circulating hot water discharge pipe 6 provided on the delivery side of the small fish 5 such as shirasu to the circulating hot water supply pipe 7 via the pump 8. It circulates to the circulating pouring pipe 7, and the upper layer is always the circulating drain pipe 6
Flow toward the delivery side of small fish in the direction.

A perforated partition plate 9 having an upper end lower than the water level is provided on the delivery side of the boiling pot 1 so as to maintain the depth at which the small fish that boil and float rise together with the hot water. The perforated partition plate 9 is formed of punching metal having a large number of pores, reduces countercurrent to the water flow in the upper layer, assists circulation of the hot water 4 by heating in the boiling pot 1, and is separated from the small fish 5. It has the effect of preventing the above-mentioned fine earth and sand or fine-walled pieces from passing through and leaving them at the bottom of the boiling pot 1 to flow out to the delivery side.

On the delivery side of the perforated partition plate 9, there is provided a mesh-shaped feed conveyor 10 for delivering the boiled small fish 5'which has been boiled and floated and flows over the perforated partition plate 9 by the water flow.
The boiled boiled small fish 5 ′ sent out by the mesh feed conveyor 10 is arranged in an inclined manner, and while the boiled boiled small fish 5 ′ mounted on the tower is fed out, it is separated from the hot water 4 and transferred to the next drainer cooling conveyor 11. To do. The flowing hot water flows back from the circulating hot water pipe 6 to the circulating pouring pipe 7, and is poured into the boiling pot 1 again to be boiled 1
Water flow is generated in the upper layer of the inside to reduce the loss of heat energy.

[0012]

EFFECTS OF THE INVENTION The present invention is that the circulating hot water from the circulation drainage pipe provided on the delivery side of boiled small fish is circulated to the circulating pouring pipe, so that the water flow in the upper layer of the boiling water in the boiling pot toward the delivery side. By utilizing the phenomenon that small fish such as shirasu rise when boiled and ripe, the boiled boiled small fish are put on this stream and allowed to boil efficiently. Therefore, uncooked or overcooked small fish will not be mixed in the product, and only appropriately boiled small fish will be sent out, so high quality products can be produced and hot water circulates Since it is used, it has an effect of effectively utilizing thermal energy and remarkably improving thermal efficiency.
