Description

Technical Field

[0001] This utility model relates to the field of rice cooling technology, and in particular to a water-cooled cooling device for rice polishing. Background Technology

[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and other processing steps. Rice contains nearly 64% of the nutrients found in paddy and over 90% of the essential nutrients required by the human body. It is a staple food for people in most parts of China. Polishing is a necessary step in rice processing, followed by cooling. Chinese patent CN110926105A discloses a water-cooling device for rice polishing. This device uses a transmission assembly to continuously move the outer cylinder and its upper components up and down, causing the rice inside the inner cylinder to vibrate. The device uses a water-cooling component to cool the rice. The transmission component and the cooling component work together to ensure uniform cooling of the rice. The hollow stirring rod rotates to stir the rice. Because the hollow stirring rod contains cold water, its low temperature accelerates the cooling speed of the rice. However, this device cools the rice by allowing cold water to enter the interior of the hollow stirring rod. Due to the limited contact area between the hollow stirring rod and the rice, the cooling effect is limited and it is not conducive to rapid cooling of the rice. Therefore, we propose a water-cooling cooling device for rice polishing. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a water-cooled cooling device for rice polishing. This invention solves the problem that while the device cools the rice by introducing cold water into the hollow stirring rod, the limited contact area between the hollow stirring rod and the rice results in a limited cooling effect, hindering rapid cooling of the rice.

[0004] This utility model discloses a water-cooled cooling device for rice polishing, comprising a support frame, four springs arranged in a matrix on the outer side of the support frame, the springs being fixedly connected to an outer frame, a cooling box inside the outer frame, a feeding trough above the cooling box, a discharging trough below the cooling box, multiple guide pipes arranged in a matrix inside the cooling box, the two ends of the guide pipes being connected to the feeding trough and the discharging trough respectively, three inverted V-shaped baffles arranged in a matrix inside the feeding trough, a water outlet pipe on the upper side of one side of the cooling box, and a water inlet pipe below the water outlet pipe.

[0005] In the above scheme, both the outlet pipe and the inlet pipe are equipped with valves.

[0006] In the above scheme, a mounting bracket is provided on one side of the lower end of the cooling box, and a vibration motor is fixedly installed on the mounting bracket.

[0007] In the above scheme, the feed tube is an S-shaped bend.

[0008] In the above scheme, both ends of the feed tube are conical.

[0009] In the above scheme, the cross-section of the feed trough and the cross-section of the discharge trough are conical and inverted conical, respectively.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a water-cooled cooling device for rice polishing. An inverted V-shaped baffle diverts the rice flow, allowing it to enter the feed tube evenly. Cooling water is injected into the cooling tank through the inlet pipe, and the cooled water, after heat exchange, is discharged through the outlet pipe. As the rice passes through the feed tube, it exchanges heat with the cooling water inside, thus achieving the purpose of cooling the rice. A vibration motor drives the cooling tank to vibrate through a mounting frame. This vibration effectively prevents the rice from clogging inside the feed tube. This cooling device has a simple structure, good cooling effect, and can quickly cool the rice, effectively improving the processing efficiency of rice. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-2As shown, this utility model is a water-cooled cooling device for polishing rice, including a support frame 1. Four springs 2 arranged in a matrix are provided on the outer side of the upper part of the support frame 1. The upper part of each spring 2 is fixedly connected to an outer frame 3. A cooling box 4 is located inside the outer frame 3. The support frame 1 and the outer frame 3 are connected by the springs 2, allowing the cooling box 4 to reciprocate vertically on the support frame 1. A feeding chute 5 is provided above the cooling box 4, and a discharging chute 6 is provided below it. Multiple guide pipes 7 arranged in a matrix are provided inside the cooling box 4. The two ends of each guide pipe 7 are connected to the feeding chute 5 and the discharging chute 6, respectively. Polished rice can be added into the cooling device through the feeding chute 5. Rice inside the feed trough 5 enters the discharge trough 6 through the feed pipe 7, allowing the cooled rice to be discharged. The feed trough 5 is equipped with three inverted V-shaped baffles 8 arranged in a matrix. When rice enters the feed trough 5, the inverted V-shaped baffles 8 can divert the rice, allowing it to enter the feed pipe 7 evenly. The upper side of the cooling box 4 is equipped with a water outlet pipe 9, and below the water outlet pipe 9 is a water inlet pipe 10. Cooling water can be injected into the cooling box 4 through the water inlet pipe 10. After heat exchange, the cooling water can be discharged through the water outlet pipe 9. When the rice passes through the feed pipe 7, it exchanges heat with the cooling water inside the feed pipe 7, thereby achieving the purpose of cooling the rice.

[0017] Both the outlet pipe 9 and the inlet pipe 10 are equipped with valves 11, which can control the opening and closing of the outlet pipe 9 and the inlet pipe 10.

[0018] A mounting bracket 12 is provided on one side of the lower end of the cooling box 4. A vibration motor 13 is fixedly installed on the mounting bracket 12. When the vibration motor 13 is working, it drives the cooling box 4 to vibrate through the mounting bracket 12. The vibration of the cooling box 4 can effectively prevent the rice from getting blocked inside the feed pipe 7.

[0019] The feed pipe 7 is an S-shaped bend. The S-shaped bend in the feed pipe 7 effectively reduces the speed at which the rice falls through the feed pipe 7, thereby increasing the heat exchange time between the rice and the cooling water and improving the cooling efficiency of the cooling device for the rice.

[0020] Both ends of the feed tube 7 are conical, and the conical ends make it easier for rice to enter the feed tube 7.

[0021] The cross-sections of the feed trough 5 and the discharge trough 6 are conical and inverted conical, respectively.

[0022] Specifically, in this invention, polished rice is fed into the cooling device through the feed trough 5. The inverted V-shaped baffle 8 diverts the rice, allowing it to enter the guide pipe 7 evenly. Cooling water is injected into the cooling tank 4 through the water inlet pipe 10. The cooled water, after heat exchange, is discharged through the water outlet pipe 9. As the rice passes through the guide pipe 7, it exchanges heat with the cooling water inside, thus achieving the purpose of cooling the rice. The S-shaped bend in the guide pipe 7 effectively reduces the speed at which the rice falls through it, thereby increasing the heat exchange time between the rice and the cooling water and improving the cooling efficiency of the cooling device. The cooled rice enters the discharge trough 6 through the guide pipe 7, allowing the cooled rice to be discharged. When the vibration motor 13 is working, it drives the cooling tank 4 to vibrate through the mounting bracket 12. The vibration of the cooling tank 4 effectively prevents the rice from clogging inside the guide pipe 7.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
