Technical Field

[0001] This utility model relates to the field of rice washing equipment technology, and in particular to a pneumatic rice washing device. Background Technology

[0002] With the fast pace of modern life and increased awareness of healthy eating, consumers have placed higher demands on the taste, nutrition, and ease of processing of rice, a staple food. In 2023, the Chinese kitchen appliance market reached approximately 190 billion yuan, with smart kitchen appliances showing significant growth. As a staple food for Asian families, the quality of rice processing directly affects its taste and the degree of nutrient retention.

[0003] Existing kitchen rice processing equipment still has some problems in rice washing. Existing rice washing equipment usually relies on water washing, which not only causes the loss of water-soluble nutrients, but also generates wastewater that is inconvenient to treat. At the same time, it is difficult to fully remove bran powder and light impurities during rice washing, which can easily lead to rice grain damage and nutrient loss.

[0004] Therefore, it is necessary to provide a pneumatic rice washing device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a pneumatic rice washing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A pneumatic rice washing device includes a housing, a rotatable inner cylinder inside the housing, a plurality of equally spaced discharge holes on the side of the inner cylinder, an air jet assembly inside the inner cylinder, a motor fixed to the bottom of the housing, a protrusion fixed to the bottom end of the inner cylinder, a gear ring fixed to the side of the protrusion, a gear meshing with the gear ring fixed to the output end of the motor, and a cleaning assembly for clearing the discharge holes connected to the air jet assembly.

[0007] As a further embodiment of this utility model, the jet assembly includes a jet column disposed at the center of the inner cylinder, the bottom end of the jet column being fixed to the bottom side wall of the outer shell, the jet column being rotatably connected to the inner cylinder via a bearing, the jet column having an inner cavity inside, the jet column having a jet hole communicating with the inner cavity on its side, and the bottom end of the jet column being connected to an air inlet pipe communicating with the inner cavity.

[0008] As a further embodiment of this utility model, the jet holes are provided in a plurality of manner and are distributed at equal intervals.

[0009] As a further embodiment of this utility model, the cleaning assembly includes a connecting rod fixed to the side of the jet column, a cleaning plate fixed to the end of the connecting rod away from the jet column, and bristles on the side of the cleaning plate that contact the inner wall of the inner cylinder.

[0010] As a further embodiment of this utility model, the top of the outer shell is provided with an opening and a cover plate is hinged to the top opening of the outer shell, and a handle is fixed on the outer side wall of the cover plate.

[0011] As a further embodiment of this utility model, a plurality of symmetrically distributed support legs are fixed to the bottom end of the outer shell, and the bottom ends of the plurality of support legs are jointly fixed to a base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. High-pressure gas is injected into the rice through the jet assembly, impacting and cleaning impurities on the rice surface. This causes residual bran and impurities to detach from the rice grain surface. The impact and shearing action of the airflow directly peels off the bran and light impurities attached to the rice grain surface. The high-pressure gas penetrates the gaps between the rice grains, ensuring thorough cleaning without dead corners. The detached impurities are quickly suspended and dispersed. Under the centrifugal force generated by the high-speed rotation of the inner cylinder, the lighter bran and impurities are effectively thrown to the periphery and quickly separated and discharged through the discharge hole. This achieves efficient separation of rice grains and impurities. This method avoids the loss of water-soluble nutrients and wastewater treatment problems caused by traditional water washing, and greatly preserves the original nutrients and flavor substances of the rice. The entire process does not require water, is energy-saving and environmentally friendly, and has a high degree of automation, resulting in thorough and efficient cleaning.

[0014] 2. The inner wall of the inner cylinder is brushed and cleaned by the cleaning components, thereby clearing the discharge hole in real time, avoiding blockage of the discharge hole, and ensuring that impurities can be discharged and separated smoothly through the discharge hole.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-6This utility model provides a pneumatic rice washing device, including a housing 3, inside which is a rotatable inner cylinder 8. Multiple equally spaced discharge holes 13 are provided on the side of the inner cylinder 8. An air jet assembly 1 is installed inside the inner cylinder 8. A motor 12 is fixed to the bottom of the housing 3. A protrusion 10 is fixed to the bottom of the inner cylinder 8, and a gear ring 9 is fixed to the side of the protrusion 10. A gear 11 that meshes with the gear ring 9 is fixed to the output end of the motor 12. A cleaning assembly 2 for cleaning the discharge holes 13 is connected to the air jet assembly 1. In use, rice is poured into the inner cylinder 8, and the motor 12 is started. The output end of the motor 12 drives the gear 11 to rotate, thereby rotating the inner cylinder 8 through the interaction of the gear 11 and the gear ring 9. The discharge holes 13 on the side of the inner cylinder 8 are smaller than the size of the rice grains to prevent rice from falling out of the inner cylinder 8. Simultaneously, high-pressure gas is sprayed into the rice through the air jet assembly 1, cleaning the rice. The surface impurities are cleaned by impact, causing residual bran and powder impurities on the rice to detach from the rice surface. This process utilizes the impact and shearing action of airflow to directly peel off the bran and light impurities attached to the rice grain surface. High-pressure gas penetrates the gaps between the rice grains, ensuring thorough cleaning without any blind spots. The detached impurities are quickly suspended and dispersed. Under the centrifugal force generated by the high-speed rotation of the inner cylinder 8, the lighter bran and powder impurities are effectively thrown to the periphery and quickly separated and discharged through the discharge hole 13. This achieves efficient separation of rice grains and impurities. This method avoids the loss of water-soluble nutrients and wastewater treatment problems caused by traditional water washing, and greatly preserves the original nutrients and flavor substances of the rice. The entire process requires no water, is energy-saving and environmentally friendly, and has a high degree of automation, resulting in thorough and efficient cleaning. The cleaning component 2 brushes and cleans the inner wall of the inner cylinder 8, thereby clearing the discharge hole 13 in real time, preventing blockage, and ensuring that impurities can be smoothly discharged and separated through the discharge hole 13.

[0026] Further as Figure 1 , Figure 3 and Figure 5As shown, it is worth noting that the jet assembly 1 includes a jet column 101 located at the center of the inner cylinder 8. The bottom end of the jet column 101 is fixed to the bottom side wall of the outer casing 3. The jet column 101 and the inner cylinder 8 are rotatably connected by a bearing. An inner cavity 104 is formed inside the jet column 101, and jet holes 102 communicating with the inner cavity 104 are formed on the side of the jet column 101. An air inlet pipe 103 communicating with the inner cavity 104 is connected to the bottom end of the jet column 101. In specific operation, an air pump is connected to the air inlet pipe 103. An airflow with a certain pressure is delivered to the inside of the jet column 101 through the air inlet pipe 103, and the high-pressure gas is evenly and finely sprayed into the rice through multiple jet holes 102 to remove impurities on the surface of the rice. Impact cleaning removes residual bran and impurities from the rice grains. The process utilizes the impact and shearing force of airflow to directly peel away the bran and light impurities adhering to the rice grains. High-pressure gas penetrates the gaps between the rice grains, ensuring thorough cleaning without any blind spots. The removed impurities are quickly suspended and dispersed. Under the centrifugal force generated by the high-speed rotation of the inner cylinder 8, the lighter bran and impurities are effectively thrown to the periphery and rapidly separated and discharged through the discharge hole 13. This achieves highly efficient separation of rice grains and impurities. This method avoids the loss of water-soluble nutrients and wastewater treatment problems caused by traditional water washing, greatly preserving the original nutrients and flavor substances of the rice. The entire process requires no water, is energy-saving and environmentally friendly, and is highly automated, resulting in thorough and efficient cleaning.

[0027] Further as Figure 5 and Figure 6 As shown, it is worth noting that multiple jet holes 102 are provided and the multiple jet holes 102 are distributed at equal intervals. In actual operation, the multiple jet holes 102 provide a way to uniformly and finely spray the gas inside the jet column 101 into the rice, thereby improving the uniformity of the air washing of the rice and improving the overall air washing effect.

[0028] Further as Figure 3 , Figure 5 and Figure 6 As shown, it is worth noting that the cleaning assembly 2 includes a connecting rod 203 fixed to the side of the jet column 101. A cleaning plate 201 is fixed to the end of the connecting rod 203 away from the jet column 101. The side of the cleaning plate 201 is provided with bristles 202 that contact the inner wall of the inner cylinder 8. When the inner cylinder 8 rotates, the inner cylinder 8 rotates relative to the cleaning plate 201, thereby brushing and cleaning the inner wall of the inner cylinder 8 through the bristles 202 on the side of the cleaning plate 201, thereby clearing the discharge hole 13 in real time, avoiding blockage of the discharge hole 13, and ensuring that impurities can be smoothly discharged and separated through the discharge hole 13.

[0029] This solution has the following working process: During use, rice is poured into the inner cylinder 8. The output of the motor 12 drives the gear 11 to rotate, which in turn rotates the inner cylinder 8 through the engagement of the gear 11 and the gear ring 9. Air pressure is delivered to the jet column 101 through the air inlet pipe 103, and then evenly and finely sprayed into the rice through multiple jet holes 102. This impacts and cleans impurities on the rice surface, causing residual bran and other impurities to detach from the rice grains. This process utilizes the impact and shearing action of the airflow to directly peel away the bran and light impurities adhering to the rice grain surface, resulting in high efficiency. Pressurized gas penetrates the gaps between rice grains, ensuring thorough cleaning without any blind spots and rapidly suspending and dispersing the removed impurities. Under the centrifugal force generated by the high-speed rotation of the inner cylinder 8, the lighter bran powder impurities are effectively thrown to the periphery and quickly separated and discharged through the discharge hole 13, thus achieving efficient separation of rice grains and impurities. When the inner cylinder 8 rotates, it rotates relative to the cleaning plate 201, thereby brushing and cleaning the inner wall of the inner cylinder 8 through the bristles 202 on the side of the cleaning plate 201, thus clearing the discharge hole 13 in real time, preventing blockage of the discharge hole 13, and ensuring that impurities can be smoothly discharged and separated through the discharge hole 13.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the top of the outer shell 3 is open and a cover plate 4 is hinged to the top opening of the outer shell 3. A handle 5 is fixed on the outer side wall of the cover plate 4. In actual operation, by opening the cover plate 4, rice can be put into the inner cylinder 8 from the top opening of the inner cylinder 8. The top opening of the outer shell 3 is sealed by the cover plate 4 to prevent the rice in the inner cylinder 8 from splashing out.

[0031] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom of the outer shell 3 is fixed with a plurality of symmetrically distributed support legs 6, and the bottom ends of the plurality of support legs 6 are jointly fixed with a base plate 7.

[0032] In summary: The jet assembly 1 injects high-pressure gas into the rice, impacting and cleaning impurities on the rice surface. This removes residual bran and other impurities from the rice grains, utilizing the impact and shearing force of the airflow to directly peel off the bran and light impurities adhering to the rice grains. The high-pressure gas penetrates the gaps between the rice grains, ensuring thorough cleaning without blind spots. The peeled impurities are quickly suspended and dispersed. Under the centrifugal force generated by the high-speed rotation of the inner cylinder 8, the lighter bran and impurities are effectively thrown to the periphery and quickly separated and discharged through the discharge hole 13. This achieves highly efficient separation of rice grains and impurities. This method avoids the loss of water-soluble nutrients and wastewater treatment problems caused by traditional water washing, greatly preserving the original nutrients and flavor substances of the rice. The entire process requires no water, is energy-saving and environmentally friendly, and has a high degree of automation, resulting in thorough and efficient cleaning. The cleaning assembly 2 brushes and cleans the inner wall of the inner cylinder 8, thereby clearing the discharge hole 13 in real time, preventing blockage and ensuring that impurities can be smoothly discharged and separated through the discharge hole 13.

[0033] The motor 12 can be purchased from the market. The motor 12 is equipped with a power supply. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be described again in the specification.
