Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice hulling machine technology, and in particular to a rice hulling device for rice processing. Background Technology
[0002] Rice, also known as paddy rice, is a food made from paddy rice through cleaning, hulling, milling, and finishing processes. Because freshly harvested paddy rice contains a high moisture content, usually around 18-22%, this moisture exists inside the paddy rice in the form of free water and bound water. Therefore, a dehulling machine is needed to dehull the paddy rice. A dehulling machine is a device that integrates multiple functions such as feeding, dehulling, screening, and hull discharge. It efficiently achieves the dehulling process of paddy rice in a mechanized manner.
[0003] According to the authorized announcement number: CN221536761U4, a utility model patent for a rice hulling device relates to the field of rice hulling technology. Its beneficial effects are as follows: damp rice with husks is placed into a drying drum to dry the damp rice with husks. The first motor drives the rotating shaft and four stirring plates to rotate, which can accelerate the drying of the damp rice with husks. Hot air is injected into the drying drum through the air outlet on the rotating shaft by the hot air box to further accelerate the drying of the damp rice with husks.
[0004] The inventors believe that the drying structure in the above-mentioned technology has some drawbacks. First, the air outlet on the rotating shaft lacks an interception structure, making it easy for rice grains to get stuck in the air outlet during the drying process, which reduces the hot air delivery and affects the drying rate. Second, the optimal drying temperature for rice should be around 45 to 50 degrees Celsius. The above-mentioned technology makes it difficult to detect the temperature inside the drying drum, which can easily lead to excessively high or low temperatures. Excessively high temperatures will cause the rice to be overheated, resulting in poor appearance and taste, as well as damaging the nutritional components of the rice and affecting its edible value. On the other hand, excessively low temperatures will lead to incomplete drying of the rice, which is not conducive to long-term storage. Utility Model Content

[0027] The drying assembly 5 also includes a housing 59 connected to the outside of the drying drum 51.
[0028] The housing 59 includes an interception net 5901, a connecting pipe 5902, and a valve 5903. The inner wall of the housing 59 is provided with an interception net 5901, which is used to intercept rice grains and prevent them from falling into the housing 59.
[0029] The bottom of the housing 59 is connected to a connecting pipe 5902, and a valve 5903 is provided on the outside of the connecting pipe 5902. The water collected in the housing 59 can be discharged through the connecting pipe 5902 and the valve 5903.

[0031] Heating tube 52 heats the inside of drying drum 51, causing moisture inside the drying drum 51 to be discharged from feeding trough 57. Temperature monitoring instrument 56 detects the temperature inside drying drum 51 to prevent the temperature from being too high or too low. Then, rice is poured into drying drum 51 from feeding trough 57 and the reduction motor 53 is started to drive the fixed shaft 54 to rotate the spiral blades 55, thereby conveying the rice. The rice can be turned over during the conveying process, which improves the drying efficiency. During this process, some moisture carried by the rice flows into the box 59. The rice is conveyed to the discharge port 58 and falls into the feeding trough 3. Example
[0032] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0033] Specifically, the outer casing 2 includes a fan 201, a discharge pipe 202, and a discharge port 203. The fan 201 is connected to one side of the outer casing 2, and the exhaust port of the fan 201 is connected to the discharge pipe 202. The discharge port 203 is opened on the inner wall of the outer casing 2. The model of the fan 201 is MQS5-54.
[0034] Specifically, the shell removal assembly 4 includes a stepper motor 41 disposed on one side of the outer shell 2, the output end of the stepper motor 41 is fixedly connected to a first rubber roller 42, and the inner wall of the outer shell 2 is rotatably connected to a second rubber roller 43 through a bearing seat.
[0035] Specifically, the shell removal assembly 4 also includes a protective cover 44 fixed to one side of the outer shell 2. One end of the first rubber roller 42 passes through one side of the protective cover 44 and is fixedly connected to a drive wheel 45. A driven wheel 46 is engaged with the outer side of the drive wheel 45.
[0036] Specifically, one end of the second rubber roller 43 penetrates the inner wall of the protective cover 44 and is fixedly connected to the inner ring of the driven wheel 46.
[0037] Stepper motor 41 and fan 201 are started respectively. Stepper motor 41 drives the first rubber roller 42 to rotate. The first rubber roller 42 drives the drive wheel 45 to rotate. When the drive wheel 45 rotates, the driven wheel 46 drives the second rubber roller 43 to rotate synchronously. At this time, the dried rice falls from the feed trough 3 into the space between the first rubber roller 42 and the second rubber roller 43. The rice is dehulled by the two sets of rubber rollers. The dehulled rice is discharged from the discharge port 203. Fan 201 draws air into the outer shell 2. Since the rice husk is lighter than the rice, the rice husk is drawn away by the fan 201 and discharged from the discharge pipe 202, thus completing the separation of rice and husk.
[0038] During use, the drying drum 51 is heated by the heating tube 52, and the temperature monitoring instrument 56 detects the temperature inside the drying drum 51 to avoid the temperature being too high or too low and affecting the quality of the rice. Then, the paddy is poured into the drying drum 51 from the feeding trough 57 and the reduction motor 53 is started to make the fixed shaft 54 drive the spiral blades 55 to rotate, thereby conveying the paddy. The paddy can be turned over during the conveying process, which improves the drying efficiency. During this process, some moisture carried by the paddy flows into the box 59, and the paddy is conveyed to the discharge port 58 and falls into the feeding trough 3.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
