That is, in a continuous steaming treatment apparatus for cereals provided with a hot water immersion section and a steaming section, at least a steaming section for finishing is provided with a net-shaped endless belt conveyor for applying steam to the grains while transporting the grains. This is a continuous cereal steaming treatment apparatus provided with a belt conveyor cleaning device having a cold water or hot water discharge device near the position of the endless belt conveyor immediately after the steamed cereals on the endless belt conveyor have been transported to the next step. The belt conveyor cleaning device includes a plurality of cold water or hot water discharge nozzles, the farther from the base for supplying cold water or hot water, the smaller the opening diameter of the nozzle, and the wider the discharge angle of cold or hot water, and the adjacent It is desirable to use a nozzle in which the distance between the nozzles is reduced. Further, the belt conveyor cleaning device can be configured to include a cold water or hot water discharge nozzle capable of reciprocating in a direction substantially perpendicular to the moving direction of the endless belt conveyor.

[Action]

According to the present invention, by providing a belt conveyor cleaning device at least near the position of the endless belt conveyor immediately after the next step of conveying the steamed grains on the endless belt conveyor in the finishing steaming section, the adhered particles adhere to the endless belt conveyor. Since the conveyor can be cleaned while the steamed grains are warm, that is, immediately after the steamed grains are conveyed, the cleaning can be performed efficiently. Further, as the belt conveyor cleaning device, comprising a plurality of cold water or hot water discharge nozzles, the farther from the base for cold or hot water supply, the smaller the opening diameter of the nozzle, and the wider the cold water or hot water discharge angle, When the nozzles having a smaller interval between adjacent nozzles are used, the discharge water pressure from each nozzle becomes uniform in the direction in which the plurality of nozzles are arranged, so that the cleaning effect of the conveyor is enhanced. In addition, if the belt conveyor cleaning device employs a configuration including a cold water or hot water discharge nozzle capable of reciprocating in a direction substantially perpendicular to the moving direction of the endless belt conveyor, the number of nozzles can be reduced.

【Example】

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a schematic side view of the continuous steaming apparatus 1. The case where rice is used as cereals will be described below. First, the washed rice is immersed in water in a primary immersion tank (not shown) and depends on the quality of the rice.
The water absorption treatment is carried out to such an extent that the water content becomes as low as possible. The water-absorbed rice is stored in the hopper 2 and a predetermined amount of rice is dispensed onto the net conveyor 3 by a predetermined amount. The net conveyor 3 is stretched in the form of an endless belt over the adjacent primary cooking chamber 5 and is driven in the direction of the arrow shown in the drawing, so that rice on the conveyor 3 is blown out from the steam blow pipe 6 on the lower side of the conveyor 3. The mixture is heated and steamed by the low-pressure, high-temperature saturated steam at about 100 ° C. to pregelatinize the starch. A hot water immersion chamber 7 adjacent to the primary steaming chamber 5 is provided with a rice feed bar conveyor 9 provided with a number of bars attached at predetermined intervals and rotatably provided in the direction of the arrow.
85 ℃ hot water is supplied. In the hot water immersion chamber 7, the rice sent from the primary steaming chamber 5 is further promoted in the pregelatinization of starch, and the amount of absorbed water (about 60%) increases. This water-absorbed rice is transferred to the next step in the secondary steaming chamber 10 in the course of moving on the net conveyor 11 from the steam blowing pipe 12 provided at the lower part of the net conveyor 11, for example, a low-pressure high-temperature saturated steam of about 100 ° C. , So that it is finished steamed. In the continuous steaming treatment apparatus 1 of this embodiment, the ingredient charging device 13 is provided on the top plate of the secondary steaming chamber 10 as shown in FIG. A scaffold 16 having a handrail 15 on which a person can ride is provided on a top plate portion, and a tool introduction device 13 is made to face the secondary steaming room 10 at a substantially central portion thereof. Although not shown on the scaffold 16, it can be easily raised by attaching a ladder. In FIG. 2, a lid which can be opened and closed is provided at the top of the ingredient charging cylinder 17.
19 is provided, and a viewing window 20 is provided on a side surface of the ingredient loading cylinder 17. The ingredient charging cylinder 17 is disposed substantially at the center of the support member 22 of the screw feeder 21 having substantially the same width as that of the secondary steaming chamber 10, and a mounting portion of the ingredient charging cylinder 17 to the support member 22 is provided. A tool guide plate 23 is extended. At the lower end of the support member 22, an ingredient inlet 24 is open. The screw feeder 21 is driven by a motor 25 disposed adjacently. In addition, a shutter 28 for opening and closing the insertion port is attached to the lower part of the tool insertion cylinder 17 so as to be able to move forward and backward. Therefore, when making cooked rice or the like, the corresponding food material is charged and when the motor 25 is driven, the screw feeder 21 crosses the width direction of the secondary steaming chamber 10, that is, the direction of movement of the conveyor 11. Ingredients are inserted evenly in the direction. The progress of the insertion can be performed while looking through the viewing window 20. Note that the lid 19 of the ingredient loading device 13 is freely openable and closable, and when the ingredient is not loaded, the processing state in the secondary steaming chamber 10 can be visually checked by opening the lid 19. In the case of steaming only the raw cereals, the device 13 is not necessary,
By closing 19, the steam does not escape from the upper portion of the charging tube 17 or becomes difficult to escape, so that the steaming efficiency can be improved. In this drawing, the ingredient charging device 13 is arranged in the secondary steaming chamber 10, but may be provided in the water absorption immersion chamber, the primary steaming chamber 5, or the hot water immersion chamber 7 depending on the food material to be used. For example, when making red rice, boiled red beans are introduced into the primary steaming room 5, the hot water immersion room 7, or the cooking device 13 in the secondary steaming room 10. Further, the ingredient input device 13 is not limited to a continuous steaming treatment device for cereals, and may be used as an ingredient input device for various food processing machines. In the present embodiment, as shown in FIG.
After the endless belt-shaped net conveyor 11 conveys white rice or cooked rice and transfers the rice to the next processing step, a high-pressure water discharge device 26 is attached immediately after the rice is turned over. The water discharge device 26 is for removing rice grains or ingredients adhered on the net of the conveyor 11 from the conveyor 11 by spraying high-pressure water. In this continuous steaming apparatus 1, since the conveyor 11 of the secondary steaming room 10 transports finished rice, soft rice grains and ingredients adhere to the net of the conveyor 11 and are the most difficult to clean. Therefore, it is efficient if the conveyer 11 can be cleaned while the rice is still hot, that is, immediately after the rice is conveyed. Therefore, the setting location of the water discharge device 26 is determined. A detailed view of the water discharge device 26 is as shown in FIGS. 3 (a) and 3 (b). That is, the water pipe 27 for washing is provided between the upper and lower conveyors 11 over the entire width of the conveyor 11, and the water pipe is provided with a number of water discharge nozzles 29. At this time, in order to make the discharge water pressure from each nozzle 29 uniform in the width direction of the conveyor 11, the nozzle diameter is reduced as the nozzle 29 is farther from the water pipe base. Further, it is preferable that the water discharge angle is wide, the interval between the discharge nozzles is narrow, and the distance between the nozzle 29 and the net 11 is about 3 to 10 cm. In addition, if the temperature of the washing water is kept at room temperature, the rice grains 30 attached to the net are hardly dropped and the net is cooled, which adversely affects the secondary steaming process, so use hot water of about 40 to 80 ° C. Is preferred. In the secondary steaming room 10, the finished rice 30 is sent on the conveyor 11 and guided to the next step by the guide 32 at the position of the pulley 31. The rice 30 attached to the inverted conveyor 11 is separated from the net by the water 33 discharged from the nozzle 29, and the water accompanied by the rice grains 30 is collected by the receiving device 35. The water pressure of this water discharge device 26 is required to be about 70 to 100 kg / cm ₂ , and the water pressure is obtained by several plunger pumps, but a large space for plunger pump installation is required, There is also a method of using only one plunger pump because the cost is increased accordingly. That is, as shown in FIGS. 4 (a), 4 (b) and 4 (c), a water pipe 37 having one
Is a device that slides sequentially over the width of
The reciprocating motion of the piston rod 40 of the air cylinder 39 attached to the apparatus body 1 is transmitted to the rack 41 and the spur gear 42, and when the sprocket 43 is rotated, the sprocket 43 is held by the guide bar 45 and attached to the drive chain 46. The nozzle block 47 slides left and right. Since the discharge port of the spray nozzle 36 is directed to the lower conveyor net 11, it is possible to blow down the rice grains 30 of the net while sliding left and right in the range indicated by the arrows in FIGS. 4 (b) and 4 (c). it can. The moving speed of the nozzle block 47 is determined according to the moving speed of the conveyor 11. A water discharge device 26 which is a cleaning device for the conveyor net 11
Is operated during or after cooking, but it is more effective to operate while the rice grains are warm. The operation may be operated either automatically or manually. In the present embodiment, the device shown in FIG. 5 can be adopted as the structure of the hot water immersion unit 7. That is, as shown in the side cross section in FIG. 5, the hot water tank 50 has a heating and heat retaining device 51 attached to the bottom thereof, and a semicircular perforated plate having a semicircular cross section from one end of the upper surface thereof. A rice immersion tank 55 is provided which includes a bottom plate 52 and side plates 53 supporting the bottom plate 52 on both sides. The height of the rice carrying-side end 52a of the bottom plate 52 is configured to be sufficiently higher than the height of the rice carrying-side end 52b,
The rice carrying side portion 53a of both side plates 53 extends from the bottom plate 52,
Also serves as a rice export guide. Both plates in immersion tank 55
A stirrer 59 having a stirring blade 57 rotating around a rotation shaft 56 supported by 53 is provided. Tip of stirring blade 57
57a is bent in the opposite direction to the direction of rotation. The water level of the hot water is adjusted by a water level detector 60. The temperature of the hot water is detected and adjusted by the temperature detector 61. In the hot water immersion section 7 having such a configuration, since the immersion tank bottom plate 52 has a porosity smaller in diameter than the rice grains, the immersion tank bottom plate 52 is filled with about 85 ° C. hot water supplied from the hot water tank 50, and The rice after the primary steaming sent from the direction shown by the dashed line near the side end 52a is guided to the stirring blade 57 by the rotation of the stirring blade 57 that slowly rotates in the direction of the solid arrow, and is subjected to hot water immersion processing. After moving, it passes over the end 52b of the bottom plate 52 on the discharge side of the rice, and is sent to the next secondary steaming step. Since the stirring blade tip bent portion 57a has the function of scraping the softened rice on the immersion tank bottom plate 52, it covers the gap between the tank bottom plate 52 and the stirring blade tip bent portion 57a, and furthermore, It is necessary that the tank bottom plate 52 and the bent portion 57a of the stirring blade tip do not mesh with each other. Therefore, of course, the tip of the stirring blade 57 may be simply bent or another member may be welded. However, as shown in FIGS. 6 (a) and 6 (b), another member 58 such as a silicon or fluorine-based resin plate is used. For example, a synthetic resin plate having a small friction coefficient may be attached.
