Description

DETAILED DESCRIPTION OF THE INVENTION a) Industrial Application Field The present invention relates to an apparatus for continuously heat-treating a large number of bivalves, such as scallops and clams.

More specifically, this is a continuous automatic steaming device that improves the heat treatment of the closed-shell muscle, that is, the scallop, which is unique to bivalves, from the perspective of improving product value, and is particularly suitable for the heat treatment of scallops, which have a huge closed-shell muscle. Regarding.

b) Prior Art Conventionally, an open steam heat treatment apparatus for general foods is described in Japanese Patent Publication No. 57-56855 by the applicant of the present invention.

On the other hand, we are well aware of the phenomenon that when a living bivalve is heat-treated, the force of the closed shell muscle (commonly known as the scallop) that closes the shell weakens as the heating progresses, and the shell eventually becomes stronger and closes.

However, such closed-shell steaming methods have the disadvantages that the closed shell nearly doubles the volume, the closed shell allows the internal juices to escape, and the flavor deteriorates. Therefore, when high-quality bivalves are steamed in high-end restaurants, the bivalves are tied up by hand in advance, or the bivalves are placed in a net. Wrapping it in cloth or cloth to prevent the shell from closing,
Bivalve molluscs are heat-treated by a so-called closed-shell steaming method.

However, this conventional closed-shell steaming method can only handle a very limited number of clams.

It belongs to the craftsmanship that takes time and effort by hand each time, and it is not efficient to continuously heat-treat large quantities of bivalves, and the closed-shell steaming method cannot be industrialized for the above reasons alone. There was no need for it because there was no profit.

C) Problems to be Solved by the Invention Incidentally, scallops, which belong to bivalves, have a particularly large closed shell muscle (scallop), and only the scallop, which is separated from other fleshy parts, has sufficient commercial value. It is famous for being traded on the market.

The inventors of the present application conducted a comparative experiment on the scallop shape of scallops produced by closed-shell steaming and those produced by closed-shell steaming, and found that changes in the shape of both before and after processing were shown in Figure 3 when the shape was due to closed-shell steaming. As shown, the diameter of the scallop (see the upper row of Figure 3) decreases by 1 to 2 cm, and the height of the scallop (see the lower row of Figure 3) also decreases by 2 to 6 cm, whereas in the case of closed-shell steaming, As shown in Fig. 4, the diameter of the scallop (see the upper part of Fig. 4) increases by 2 to 5@II, while the height of the scallop (see the lower part of Fig. 4) increases by 0.
~3 ■ The phenomenon of shrinkage, that is, when bivalves are heat-treated without being left open, the scallops uniformly shorten and become smaller in both diameter and height, and their visual commercial value decreases. On the other hand, when bivalves are heat-treated by suppressing their opening, their height is reduced, but their diameter uniformly increases, increasing their visual commercial value. I discovered a phenomenon.

Based on the above-mentioned viewpoint, an object of the present invention is to produce scallops with high commercial value by continuously and automatically heat-treating a large amount of bivalves in the captured state without any external binding process. d) Means for Solving the Problems In order to achieve the above object, the present invention provides the following means, namely, a cylindrical shape having a desired length having an inlet and an inlet. A conveyor for conveyance is installed inside the body, and a steam pipe having a large number of ejection holes is arranged along the conveyor, and the conveyor is provided at least within a range from an initial position of steam spraying of the conveyor to a desired position. It is proposed to install a conveyor to prevent bivalve shells from closing, which runs along the conveyor.

Alternatively, the present invention provides the following means, that is, protrusions for preventing retention are arranged in a row along the width direction at predetermined intervals on the upper surface of the conveyor for conveyance, while replacing the conveyor for preventing shell closure. The above object can also be achieved by providing a fixing surface for preventing shell closure along the travel path.

e) Effect When the bivalves are placed one after another on a transport conveyor and transported into the cylindrical body, they are eventually sprayed with saturated steam, but 2
From the initial stage of steam spraying to the desired position, the shellfish is
The shell progresses while being sandwiched between a conveyor for conveyance and a conveyor for preventing opening or a fixed surface, and is steam-cooked during that time, forcing the shell to close until the shell-closing force of the shell-closing muscles is lost.

As shown in FIG. 4, the shape of the closed shell muscle (scallop) that has been steamed for 1 to 2 minutes in a closed shell state is somewhat reduced in height, but its diameter is expanded by 2 to 5 I.

The bivalves that have been steamed in a closed shell state are then steamed for 2 to 3 minutes while being released from the pressure of a conveyor or fixed surface to prevent opening, and then transported out of the cylindrical body. .

The protrusions on the conveyor prevent the bivalves from accumulating and ensure smooth conveyance.

f) Embodiment A specific embodiment of the present invention will be described in detail below with reference to the drawings.

In the embodiment shown in FIGS. 5 and 6, the cylindrical body 1 shown in FIGS. 1 and 2 has four horizontal cylinders 11. lla, l
lb, llc, two inclined cylinders 12.12a, and five bellows 13.13a, 13b, 13c, 13d that flexibly connect between them. .14a, 14b
, 14c, 14d, 14e, 14f.

14g, 14h, and 14i are installed at a predetermined height in the air, and a cleaning window 15.15a is provided on the side surface of each horizontal cylinder.
15b, 15c, 15d, and 15e, and cleaning windows 16.16a, 16b, and 16c are attached to their bottom surfaces, respectively, while inspection windows 17 are provided on both sides of the third horizontal cylinder 11b. The conveyor 2 for transporting bivalves to which .17a is attached consists of an endless net or endless slat that runs through the inside of the cylindrical body 1, and includes a pulley 2a provided on the outside of the entrance of the cylindrical body 1, and a pulley 2a provided on the outside of the entrance of the cylindrical body 1. The rack is passed between a pulley 2b provided on the outside, and projections 2C are attached at regular intervals on the conveyor along the width direction. As shown on the right side of FIGS. 5 and 6, the pulley 2b is connected to a drive source 2e via a continuously variable transmission 2d.

Steam pipes 3, 3a having a large number of ejection holes.

3b and 3c are arranged along the conveyor 2 inside the cylindrical body l. The control temperature of saturated steam is, for example, 97 to 99
℃, the pressure of the steam pipe is, for example, 6 to 8 kg/
cm"G, secondary side 0.2~0, 5 kg/cm"
G, pressure just before blowing 0.05 to 0, 1 kg/ca
b”G.

The conveyor 4 for preventing opening is made of an endless net or an endless slat, and within a range from the initial position of the transport conveyor 2 to a desired intermediate position, the conveyor 2
It is attached so that it can accompany you along the road. It is desirable that the pulleys 41, 42, 43 supporting the conveyor 4 be constructed so that the suppression can be adjusted by springs or pneumatic means (not shown).

Nets 5 for preventing extrusion are stretched on both sides between the conveyor 4 for preventing opening and the conveyor 2 for conveyance.

In such a configuration, when bivalves are placed one after another on the conveyor 2, that is, on the conveyor 2 which is reversed by the pulley 28 and advances into the cylindrical body l, the bivalves are It is sandwiched between the conveyor 2 and the conveyor 4 for preventing opening, which runs directly above the conveyor 2, and gradually ascends the inclination part A, and eventually reaches the horizontal steaming part B, where steam is spewed out. This section of the horizontal steaming section B also progresses over a period of about 1 to 2 minutes, with the bivalves being sandwiched between the transport conveyor 2 and the opening prevention conveyor 4.
During this time, the flesh of the bivalve mollusk becomes dead.
Since the purpose is to steam the shellfish to death in a closed shell state, the opening prevention conveyor 4 is no longer required in the next progressing section, that is, the steaming horizontal section C, and only the conveyor 2 runs, and this C It takes, for example, 2 to 3 minutes to pass through the section.

Even if the bivalve shell is opened in this section C, the effects of the present invention will not change.

In the figure, 6 is a deck for workers, and 7 is a control panel.

Instead of the conveyor 4 for preventing opening in the illustrated embodiment, it is also conceivable to provide a net-like fixing surface (not shown) for preventing opening along the running path. In this case, the bivalves on the transport conveyor 2 come into contact with the stationary fixed surface and have a tendency to brake their progress and stay there. However, the protrusions 2c provided at predetermined intervals on the transport conveyor This action prevents it from stagnation and allows it to be transported smoothly.

The embodiments shown in the specification and drawings are illustrative and not limiting (the present invention extends to all modifications that do not depart from the technical idea described in the claims).

g) Effects of the Invention As detailed above, the present invention provides a conveyor 4 for preventing opening along the transport conveyor 2 at the beginning of the process of continuously and automatically heat-treating a large amount of bivalve molluscs in an open manner with steam. Alternatively, a fixed surface (not shown) may be provided to force the closed shell.
Since the configuration is such that the shells can be continuously and automatically steamed, the shape of the steamed closed shell muscles (scallops) can be produced in large quantities, with the diameter uniformly increasing by 2 to 5 mm compared to that of open steaming. It became so.

When scallops with enlarged diameters are served at the table, they look larger and more sophisticated than conventional scallops, and their commercial value is highly evaluated, which benefits both consumers and suppliers.
