DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a continuous cooking apparatus will be described below with reference to the drawings.

As shown in FIG. 1, the continuous cooking apparatus 1 is
Primary steaming part A in which rice grains that have been subjected to the primary immersion treatment supplied from the hopper 2 are steamed by the heated steam blown out from the steam pipe 5 while being transported at a constant speed by the mesh belt conveyor 4.
And a secondary soaking section B in which rice grains continuously supplied from the primary steaming section A are transferred by a scraper conveyor 7 while being immersed in wet water in a heated water tank 6, and continuously supplied from the soaking section B Similar to the primary steaming section A, the rice steamed is constituted by a secondary steaming section C in which the mesh belt conveyor 8 transfers the rice grains to the extracting section 9 at a constant speed and steams the heated rice steam blown from the steam pipe 5.

The primary steaming section A, the secondary steaming section B, and the secondary steaming section C are sequentially arranged in the tunnel 3 to prevent foreign substances and germs from entering by being isolated from the outside, and also to prevent steam and heat from outside. To prevent the escape.

At the rear end of the mesh belt conveyor 4 in the primary steaming section A, the first loosening machine 10a is connected to the secondary steaming section C.
The second loosening machine 10b is attached to the front part of the mesh belt conveyor 8 in FIG. If necessary, a loosening machine may be attached to the middle part or the rear end of the machine.

Although not shown in the drawing, a liquid injection nozzle for spraying oil for seasoning or releasing or polishing on the rice grains to be conveyed is also provided at an appropriate position, for example, above the mesh belt conveyor 8 in the tunnel 3.

In the primary steaming section A, the mesh belt of the mesh belt conveyor 4 is formed from a fine mesh stainless steel net or the like. The steaming action is performed by being blown into the pile of rice grains being transferred between the guide plates 11 on both sides thereof as shown in FIG.

The heating water tank 6 of the secondary immersion part B has a horizontal surface 6a extending from the front part to the central part, a rearward upward inclined surface 6b continuous with the horizontal surface 6a, and a guide surface 6c hanging from the inclined surface 6b at a steep inclination. Have The inclined surface 6b has an inclination of about 20 to 40 degrees as shown, and the guide surface 6c has an inclined surface 6b.
It is formed with an inclination of 50 to 70 degrees with respect to b.

The inclined surface 6b extends higher than the surface of the hot water in the heated water tank 6 and also functions as a draining surface. In the heated water tank 6, a conveyance path 34 by a guide frame that is continuous with the chute 16 from the mesh belt conveyor 4 is arranged along the horizontal portion 6a and the inclined portion 6b so that the bottom surface thereof is in close contact. A heating steam pipe 35 is arranged in the hot water so as to surround the outside of the transport path 34.

The scraper conveyor 7 includes the scraper plate 1
2 moves in the conveyance path 34 along the bottom thereof, and the rice grains supplied into the conveyance path 34 through the chute 16 are heated in the heating water tank 6
The inside is sequentially transferred from the horizontal surface 6a to the inclined surface 6b, and the guide surface 6
It is designed to be sent to c.

During this time, the rice grains are kept in the immersed state while they are in the hot water. Since this dipping is the dipping after the primary steaming, it becomes easy to permeate the inside of each rice grain, and the dipping time can be arbitrarily determined by the distance of the dipping state and the speed of the scraper conveyor 7, and the predetermined dip Subsequent immersion can be satisfied.

The secondary steaming section C has the same structure as the primary steaming section A. However, in this secondary steaming section C, the soft rice grains that have been cooked or close to this tend to stick together and harden, and also stick to the guide plates on both sides to increase the feed resistance. In addition to providing 10b in the front part, it is preferable to further provide third and fourth loosening machines in the middle part and the rear end. As a result, in addition to sufficiently exerting the leveling action for uniformizing the loosened rice grain deposition thickness, the feeding assist function is improved.

Next, an example of sushi rice cooked by the continuous steaming apparatus 1 having the above-mentioned structure will be described. First, in the primary steaming section A, the raw rice is heated by the steam from the steam pipe 5 while being conveyed by the mesh belt conveyor 4 until it is completely gelatinized. Therefore, the steam temperature used is 95 to 100 ° C,
The water vapor passage pressure is 0.15 KgH ₂ O / cm ² , and the feeding time is about 10 minutes. Next, the hot water in the heating water tank 6 in the secondary immersion part B is heated to around 90 ° C.
It is heated for about 8 to 10 minutes while being fed with the rice after primary steaming by the scraper conveyor 7 and transferred, but the tank contains about 10% sugar solution,
Rice grains absorb this rapidly and become moist. The absorption and wetting of the sugar solution at around 90 ° C. does not cause charring, and the absorption of sugar is much more, and the starch particles are sufficiently filled.

After this, the rice grains are drained by being transferred on the inclined surface 6b by the scraper plate 12 of the scraper conveyor 7 and the excess sugar on the surface is removed, and then treated in the next secondary steaming section C. Be shared with. Here the steam pipe 5
It is heated again with steam from the above to completely wet it and dry the surface of the rice grain to facilitate the later absorption of the combined vinegar. The steam temperature and passing pressure in this step were the same as those in the primary steaming section A, and the feeding time was set to 12 minutes, which was sufficient.

The cooked white rice is mixed with vinegar as usual, but if the mixed vinegar is also mixed with the sugar solution in the heating water tank 6, it can be immediately used in the freezing step after cooking.

Even if the sushi rice produced in this manner was frozen by the conventional freezing method, the thawed sushi had the same quality as the raw sushi and the aging rate was slow.

In the above-described steaming step, rice grains, treatment liquid, etc. fly around, fall, or come into contact with each other and adhere to each part of the device in the tunnel 3 and each part of the inner surface of the tunnel 3.

On the other hand, since most of the work and steps in the tunnel 3 are steam treatments as described above, each part in the tunnel 3 becomes dry. Therefore, the attached rice grains and the treatment liquid are likely to be dried and solidified, and become difficult to remove with the passage of time. Further, since the humidity and temperature of the tunnel 3 are under favorable conditions in which various bacteria can easily propagate, the adhering matter is a sanitary problem, but this is also difficult to remove.

Therefore, it is necessary to remove these regularly or as required.

For this reason, in this embodiment, spin nozzles 101 for cleaning are provided at various places in the ceiling of the tunnel 3 as shown in FIGS. 1 and 2, and the hoppers 2 in front of and behind the tunnel 3 are provided.
A cleaning nozzle 102 or the like is also provided on a transfer conveyor (not shown) for the next process or the like as needed.

The spin nozzle 101 has its own ejection port 109.
It is configured to rotate by the reaction force when the pressurized fluid is ejected from (FIG. 3).

Specifically, the spin nozzle 101 is shown in FIG.
As shown in (a) to (c) of FIG. The spin nozzle 101 has a cleaning liquid supply line 111.
The supply nozzle 104 is rotatably supported by the supply nozzle 104 by penetrating its center from the rear end wall to the front end wall, and is prevented from coming off by the nut 105 screwed to the front end of the supply nozzle 104. There is. 106, 10
Reference numeral 7 denotes a slide washer that reduces friction with the supply conduit 111, the supply nozzle 104, and the nut 105 when the spin nozzle 101 rotates.

The supply nozzle 104 is the spin nozzle 10 described above.
A plurality of jet outlets 108 are formed in the circumferential direction in the nozzle 1. The jet outlets 108 open in a direction inclined with respect to the radial direction in the direction of rotating the spin nozzle 101. As a result, the cleaning liquid ejected from the ejection port 108 of the supply nozzle 104 is the spin nozzle 1
Nozzle 101 which is blown obliquely onto the inner surface of 01
Ru a rotational force is given rotation to.

Further, the spin nozzle 101 is located at a position eccentric from the rotation axis , and has a slit-shaped jet port 109 parallel to the axis line that is opened from both the front end wall and the rear end wall to the side peripheral wall.
Are provided at two positions, a position near the rotation axis and a position far from the rotation axis , and these two ejection ports 109 are provided on both sides of the rotation axis so that they are point- symmetrical with respect to the rotation axis . .

As a result, the pressurized cleaning liquid jetted into the spin nozzle 101 fills the spin nozzle 101 and is jetted from the jet port 109 of the spin nozzle 101.

This jet port 109 is of the spin nozzle 101.
Since it is in an eccentric position from the center of rotation,
The reaction force of the jet cleaning liquid that is rotating causes the spin nozzle 101 to rotate.
And the spin nozzle 101 is in the direction shown in FIG.
Spout cleaning that is rotated at high speed and spread in the axial direction
The liquid is repeatedly ejected within a range of 360 ° around the axis of rotation.

Further , the ejection is performed strongly and vigorously by the throttling effect of the ejection port 109. Then, as shown in FIG. 3 , the spin nozzle 1 on a vertical plane passing through the rotation axis.
It becomes an injection port to the whole 360 ° range around 01
Therefore, the jet nozzle is in a jet state in which the jet nozzle spreads at a large angle at the jet nozzle having few rotation axes, and the circumference of the spin nozzle 101 on a plane passing through the center line of the spin nozzle 101 is reduced.
It is possible to eject in the range of 0 °. However, the above 360 °
The ejection to the other side is fully accompanied by the rotation of the spin nozzle 101.
It is sufficient to add, and the jetting into the 360 ° range is spin-nozzle.
Distributed at different angular positions around the axis of rotation of le 101
May be achieved. In addition, as described above,
You can be satisfied with just one side.

[0041] Thus, pressurized cleaning liquid with strong momentum from the spin nozzle 101 is spin nozzle 10 to be 360 ° range in any direction around the spin nozzle 101
1 or a large amount of ejected without evenly in all high speed in the direction of the comparatively act without evenly on the inner surface of each part of the device and the tunnel 3 in the tunnel 3, strongly fell hard deposited by vigorous plume rice grain and oil, Even with the treatment liquid, it can be automatically washed and removed in a short time while being strongly wetted, decomposed, or solubilized.

In addition to the spin nozzle 101, a cleaning liquid supply conduit 111 from the cleaning liquid supply device 100 as shown in FIG. 4 is connected to the nozzle 102.

The cleaning liquid supply device 100 has a cleaning water supply tank 112 and a chemical liquid supply tank 113.
Pumps 114 and 11 are provided on the way to the tanks 112 and 113, respectively.
Wash water supply line 116 and chemical solution supply line 1 having 5
17 is connected, and the chemical liquid supply line 117 is connected to the middle of the cleaning liquid supply line 116 via the check valve 118.

The tip of the cleaning liquid supply pipe 116 is connected to the cleaning liquid supply pipe 111 via a known static mixer 119.

As a result, whether the pumps 114 and 115 are driven independently or simultaneously are driven, either the cleaning water in the cleaning water supply tank 112 or the chemical solution in the chemical solution supply tank 113 is installed in the cleaning solution supply pipeline 111. One can be supplied at different times, or both can be supplied under pressure simultaneously. When both the wash water and the chemical solution are supplied at the same time, they are mixed by the static mixer 119.

A steam pipe 121 is provided in the cleaning water supply tank 112 to heat the cleaning water and maintain it at a predetermined temperature advantageous for the cleaning, for example, about 80 ° C.

Return paths 122 and 123 to the wash water supply tank 112 and the chemical solution supply tank 113 are branched in the middle of the wash water supply pipeline 116 and the chemical solution supply pipeline 117, and a pressure gauge is provided in the middle of each of them. 124, 125 and on-off valves 126, 127 are provided.

When an abnormal pressure is detected by this, the on-off valves 126 and 127 are opened manually or automatically to remove one of the cleaning water and the chemical solution supplied into the cleaning water supply pipeline 116 and the chemical solution supply pipeline 117. The return path 122, 123
It is possible to return to the supply tanks 112 and 113 through the above and eliminate the different pressure. Further, each of the mesh belt conveyors 4 and 8 has a path through a part of the cleaning tanks 128 and 129 so that it can be repeatedly exposed to the cleaning liquid. A steam pipe 130 for heating the cleaning water is provided in each of the cleaning tanks 127 and 128.

The steaming apparatus 1 of the present embodiment is automatically controlled by the control circuit 231 including a device for washing rice before and after it and a primary soaking process, and a device for transporting cooked rice to the next step. is there.

This control circuit 231 uses, for example, a microcomputer, and mainly controls the operation of each part in sequence, but supplies the cleaning liquid to the spin nozzle 101 and the nozzle 102 in the course of finishing the cooking by this control. Is also automatically controlled so that a predetermined cleaning is achieved.

For this cleaning control, the cleaning liquid supply line 1
Electromagnetic valves 241 to 246 are provided in the middle of the connecting pipes from 11 to the spin nozzles 101 and the nozzles 102, and are controlled by the control circuit 231 together with the pumps 114 and 115.

The control of the steaming process and the control of washing are variously performed by input from the operation panel 247 connected to the control circuit 231.

A specific example of washing control will be described. After a predetermined amount of rice is weighed, the rice is washed and then subjected to a primary dipping treatment, and then fed to the steaming apparatus 1 through the hopper 2 and continuously cooked and conveyed to the next step. To be done.

After the final rice has been subjected to washing, no new supply is carried out, and the final rice is sequentially transferred to the primary dipping section, the hopper 2, the primary steaming section A ... Without any subsequent rice. Go.

In the hopper 2 part, the primary steaming part A, etc., after the final rice has passed, there is no rice and the same tendency of drying as the inner surface of the tunnel 3 is exhibited, and the attached rice grains rapidly solidify. Try to stick.

Therefore, the washing water is sprayed into a predetermined range immediately after the final rice has passed, so that washing and rinsing are performed.

For this reason, the solenoid valves 241 and 242, 243, 244, 245, 246, ... Are opened with a necessary time difference according to the time when the final rice passes while connecting the pump 114 to the driving state. .

As a result, the rice grains attached to each part of the equipment installed in the tunnel 3 and each part of the inner surface of the tunnel 3 are washed with a high temperature washing liquid immediately after the final rice has passed and before it solidifies. It is sprayed evenly, is quickly wetted, and is sufficiently washed and removed by the powerful jet flow and its jet pressure.

In the first step of this cleaning, it is sufficient if the adhered rice grains and the like are moistened and peeled from the adhered place. Therefore, in the initial cleaning stage, warm water in the heated water tank 6 of the secondary immersion part B or warm water in the cleaning tanks 127 and 128 may be used to reuse the warm water after use in those tanks. Absent. Further, this allows the hot water in each tank to be renewed and prepared for the next use.

Only when the wetting and peeling of the adhered substances are sufficiently achieved, the pump 114 is operated to supply the wash water in the wash water supply tank 112, so-called rinsing is performed, and the final peeling and removal are performed. It is sufficient to achieve the flushing of objects.

It is also conceivable to leave a predetermined time between the cleaning and the rinsing.

When the cleaning is completed, both pumps 114 and 115 are driven simultaneously, and both the cleaning water and the chemical solution are mixed by the static mixer 119 to spin nozzle 10.
1 and the nozzle 102. In this case, a suitable mixing ratio is about wash water: chemical solution = 100: 1, and each part after washing can be sterilized.

This chemical solution is used for sterilization of canned foods and the like, and a residue of about 0.1 PPM is allowed.
However, since it evaporates at about 70 ° C. or higher, it will be emitted when the next cooking is restarted, and there is no concern about the influence of residue.
