Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous heat treatment apparatus for food materials, and more particularly to a continuous heat treatment apparatus for food materials using a tunnel-shaped treatment chamber composed of a heat source and a plurality of covers.

[0002]

2. Description of the Related Art FIG. 15 shows a bamboo ring as an example of the conventional continuous heat treatment of food materials. Takewa is a fish paste (11)
The skewer bar (10) coated with is molded by a molding machine (32),
This is transferred to a furnace composed of a heating body (35) and a cover (34), the skewer rod (10) with the surimi (11) is transferred by a conveyor (33), and is passed through the furnace while rolling. It is the one to bake bamboo rings.

[0003]

In the prior art shown in FIG. 15, the bamboo rings are baked while passing through a long tunnel-shaped furnace covered with a cover (34). When an abnormality occurred in the furnace, the operation of the continuous heat treatment furnace had to be stopped, such as stopping the chain conveyor of the transfer means. There is a problem that stopping the furnace in continuous operation also stops the operation of the entire manufacturing plant, resulting in a decrease in operation efficiency. Also, if you want to adjust the baking condition,
There was a problem that it was not possible to respond promptly in a long tunnel furnace. As a countermeasure to this problem, it has been proposed to divide the cover of a long furnace, but it is equipped with a means for opening and closing the cover safely and promptly during continuous heat treatment. Was not.

[0004]

It is rotatably suspended by a pin (4). Next, as shown by the dotted line in FIG. 3, the handle (23) is lifted and the cover (18) is moved in the arrow direction. As shown in FIG. 4, when the cover (18) is further lifted and the cover (18) is opened, the long legs (2) of the locking tool (1), which is attached to the supporting rod (5) in a suspended state, is The frame (14) is lifted so as to be in contact with the side surface of the frame (14).

Since this rotates about the hinge of the end of the frame (19), the position of the pin (22) shifts to the left and the support rod (5) tilts as the cover is opened. Therefore, the locking tool (1), which is attached to the support rod (5) while being hung by the pin (4), moves to the left side in a suspended state, and a part of the locking tool (1) is moved to the base frame ( It is lifted so as to contact the side surface of 14). Then, when it is lifted to the position shown in FIG. 5, the short leg portion (3) of the locking tool (1) is lifted to the upper end portion of the base frame (14).
Here, the cover (18) is stopped and the cover (18) is held in the open state by the support rod (5).

Next, the operation of closing the cover (18) will be described. When the cover (18) is stopped at the position shown in FIG. 5 and is further opened in the direction of the arrow (upward), the long leg (2) is pulled from the side surface of the base frame (14) as shown in FIG. It is placed on the upper end surface of the frame (14). When the cover (18) is lowered from that state as shown by the arrow in FIG. 7, the fastener (1) of the support rod (5) rotates in the direction of the arrow. And further, as shown by the arrow in FIG.
Is lowered, the locking tool (1) of the support rod (5) is rotated in the direction of the arrow, and the cover (18) is closed. By lifting and lowering the grip (23) in this way, the cover (18) can be supported by the support rod (5) when opened, and when the cover (18) is closed, it is lifted up a little to cover it. By lowering the weight of (18) downward, the locking tool (1) of the support rod (5) can be easily stopped and released.

The operation of baking bamboo rings with the continuous heat treatment apparatus shown in FIGS. 1 and 2 will be described. The skewer rod (10) with the bamboo ring (11) is hung on the protrusion of the chain conveyor (12) and is rotated by the endless belt (13), while being formed by a plurality of covers (18) in the direction of the arrow. Transfer to room. The tunnel-shaped processing chamber is heated by the heating source (16), and the bamboo ring (11) is baked. In the heat treatment for baking the bamboo rings (11) in the tunnel-shaped processing chamber, the heating status of the tunnel-shaped processing chamber and the baking condition of the bamboo rings are checked. Depending on this heating condition and the baking condition of the bamboo rings, the individual openable and closable covers can be opened at appropriate positions, or the open covers can be safely and quickly operated to safely and promptly Adjust the heating status and the condition of the bamboo rings.

As described above, by independently opening and closing the cover at appropriate positions, the temperature and the influence of the outside air during the heat treatment are adjusted so that the unevenness of the burnt surface and the variation of the burning color do not occur. The bamboo rings (11) can be baked. Although the heating condition of the tunnel-shaped processing chamber can be adjusted by sensing the temperature with a sensor and controlling the temperature and temperature distribution, there is a time lag in dealing with it, so the temperature will rise too much in continuous heating processing. In some cases, the surimi surface may be burnt too much.
The temperature can be quickly adjusted by opening any one of 8). Further, when unevenness occurs in the burn due to the variation in the temperature distribution, the temperature distribution can be adjusted by opening the cover at an appropriate position among the plurality of covers (18). When it is in an appropriate state, the tunnel-shaped processing chamber can be automatically controlled by a sensor.
