Description

Technical Field

[0001] The utility model relates to the technical field of rice processing auxiliary equipment, in particular to a rice cooling device. Background Art

[0002] Rice processing requires the use of a rice mill. The rice processed by the rice mill usually has a high temperature. In order to facilitate subsequent packaging, it needs to be cooled for a period of time, or a rice cooling device can be used to accelerate cooling (i.e., cooling rice). Natural cooling takes longer, while a rice cooling device can shorten the time, so it is more efficient. In the prior art, the rice cooling device is generally a vertical box structure. By introducing cold air into the box, the processed rice is in contact with the cold air in the box to achieve the cooling of the rice. In order to increase the residence time of the rice in the box to fully exchange heat with the cold air, multiple sieve plates from top to bottom are usually set. After the rice enters from the upper end, it moves downward through layers of sieve plates, and the cold air passes through the sieve plates to cool the rice, and finally achieves cooling of the rice. However, after the rice is cooled, it needs to be collected and then sent to the next process through a conveying pipe, or sent to a conveying pipe and then sent to the next process through a conveying pipe. Additional time is required, resulting in no improvement in efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In an exemplary embodiment, Figure 1 As shown, the present embodiment provides a rice cooling device, which includes a horizontal conveying pipe 1, wherein a feed hopper 2 connected thereto is fixedly connected above one end of the conveying pipe 1, and a discharge pipe 3 connected thereto is fixedly connected below the other end; a heat exchange pipe 4 extending from one end to the other end is also arranged in the conveying pipe 1, and both ends of the heat exchange pipe 4 are respectively fixedly extended to the outside of the conveying pipe 1; a blower 5 for supplying air into the conveying pipe 1 is also connected to one end of the conveying pipe 1 close to the feed hopper 2, and an exhaust fan 6 is also connected to the other end, and an air inlet pipe of the exhaust fan 6 is connected to the conveying pipe 1.

[0023] In the above embodiment, the feed hopper 2 can be placed below the discharge port of the rice milling machine for direct rice entry, and then transported to the other end with the cooperation of the blower 5 and the exhaust fan 6, and then discharged through the discharge pipe 3, and the discharge pipe 3 can be placed above the feed port of the next process (or lifted to the above the feed port of the next process by a lifting device), and the heat exchange pipe 4 can be introduced with a cooling medium to cool the rice, and the air sent in by the blower 5 can also assist in cooling, so that the rice can be cooled during the transportation process, thereby shortening the overall processing time and solving the problem of the prior art that the rice needs to be transported through the conveying pipe 1 after cooling, which increases the processing time. This solution realizes the cooling of the rice during the rice transportation process. In addition to providing transportation power, the blower 5 also plays the role of introducing cold air. The heat exchange pipe 4 introduces the cooling medium at one end and discharges the cooling medium at the other end. The cooling medium can be cold water. Such a combined effect makes the rice cooling efficiency better, and also completes the rice transportation, and the overall processing efficiency is also improved accordingly.

[0024] The exhaust fan 6 can also assist in making the introduced air be discharged faster, thereby carrying out the heat, and also assist the air supply fan 5 to make the rice move more smoothly. At the same time, the rice can also collide with the heat exchange tube 4 during the movement, and the heat exchange tube 4 can also be arranged in a spiral shape, so that the rice and the heat exchange tube 4 can contact efficiently, thereby playing a certain stirring role on the rice, which is more conducive to cooling.

[0025] like Figure 1 As shown, in a further exemplary embodiment, the conveying pipe 1 is also fixedly connected to a slag discharge pipe 7 located between and below the discharge pipe 3 and the exhaust fan 6. Some lighter broken rice or impurities (such as rice husks) will be guided to a farther place by the airflow and thus discharged from the slag discharge pipe 7, thereby being able to remove impurities from the rice to a certain extent.

[0026] like Figure 1-3 As shown, in a further exemplary scheme, a reducing cylinder 8 located between the discharge pipe 3 and the slag discharge pipe 7 is fixedly connected in the conveying pipe 1, and the reducing cylinder 8 is arranged concentrically with the conveying pipe 1, and the reducing cylinder 8 has an inner diameter that is large at one end and small at the other end, and the lower edge of the larger end is connected to the discharge pipe 3. The arrangement of the reducing cylinder 8 can provide a certain blocking effect on the rice at the front end of the slag discharge pipe 7, so that the rice returns to the discharge pipe 3, while the lighter rice can move over the reducing cylinder 8 to the slag discharge pipe 7 at the rear and be smoothly discharged; in more detail, the reducing cylinder 8 is also fixedly connected to a diameter enlarging cylinder 9 with one end horizontally transitioning thereto and the other end enlarging outward, and the lower edge of the larger end of the diameter enlarging cylinder 9 is connected to the slag discharge pipe 7, which can avoid the occurrence of a fault between the reducing cylinder 8 and the slag discharge pipe 7, resulting in the accumulation of impurities at the fault;

[0027] More specifically, the delivery pipe 1 is also provided with a plug plate 10 located between the reduced diameter cylinder 8 and the enclosing cylinder 9, and the plug plate 10 can partially block the reduced diameter cylinder 8 and the enclosing cylinder 9. The plug plate 10 can partially block the delivery pipe 1 and adjust the internal size of the reduced diameter cylinder 8. In this way, the size of the channel at this location can be increased or decreased. When there are more impurities, it can be increased, and when there are fewer impurities, it can be decreased. Further, a cylindrical section 11 is provided between the reduced diameter cylinder 8 and the enclosing cylinder 9, and two sides of the cylindrical section 11 are provided for the plug plate 10 to be inserted. A pair of slots 12 are provided, and an insertion frame 13 connected with the two slots 12 and for inserting the plug board 10 is provided above the delivery pipe 1. The plug board 10 is inserted from the insertion frame 13, and the two sides cooperate with the two slots 12 to achieve plug-in connection. In more detail, the plug board 10 is also provided with a plurality of plug holes 14 that can be located outside the delivery pipe 1, and one of the plug holes 14 is also penetrated by a limit rod 15 that can be abutted against the delivery pipe 1. The limit rod 15 can adjust the relative position between the plug board 10 and the delivery pipe 1, and at the same time, relatively lock them.

[0028] like Figure 1 As shown, in a further exemplary embodiment, an inclined hole plate 16 is fixedly connected to the conveying pipe 1. The inclined hole plate 16 is inclined and the lower end faces the exhaust fan 6 and extends into the slag discharge pipe 7. A plurality of through holes are also provided on the inclined hole plate 16. The through holes on the inclined hole plate 16 can allow airflow to pass through without affecting the operation of the blower 5 and the exhaust fan 6. At the same time, the inclined hole plate 16 can prevent impurities from continuing to move toward the exhaust fan 6, thereby allowing the impurities to enter the slag discharge pipe 7 more smoothly.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
