A dry and wet material mixing machine for rice noodle processing

Abstract

This utility model relates to the field of rice noodle production technology, and more specifically, to a dry and wet material mixing machine for rice noodle processing, which includes a frame, a rotary drive assembly, a stirring assembly, and a stirring box with a stirring chamber. The stirring assembly includes a rotating shaft, a first spiral ribbon, and a second spiral ribbon, with the rotating shaft connected to the power output end of the rotary drive assembly. Both the first and second spiral ribbons are spirally wound around the outside of the rotating shaft and maintain a distance from the outer surface of the rotating shaft. The spiral direction of the first spiral ribbon is opposite to that of the second spiral ribbon, and their pitches are different. The first and second spiral ribbons can generate an efficient crossflow effect and radial throwing motion of the dry and wet materials, forcing the dry and wet materials to exchange rapidly in the axial and radial directions of the rotating shaft. Due to the different pitches of the two spiral ribbons, the materials can be subjected to strong radial diffusion and strong axial convection simultaneously in the stirring chamber, forming an interlaced flow field. This forces the agglomerated clumps to be pulled in different directions, which can more effectively break up the rice noodle clumps and achieve microscopic uniformity of moisture and powder.

Description

Technical Field

[0001] This utility model relates to the field of rice noodle production technology, and more specifically, to a dry and wet material mixing machine for rice noodle processing. Background Technology

[0002] Rice noodles, also known as rice vermicelli or rice rice noodles, are a type of noodle food made primarily from rice and supplemented with starch. The processing of rice noodles mainly includes washing, soaking, grinding or pulverizing, fermentation (or non-fermentation), mixing, extrusion molding, aging, and drying. The quality and taste of rice noodles highly depend on the uniformity of the raw material mixing and the stability of the processing. During rice noodle production, it is usually necessary to thoroughly mix the pulverized wet rice flour or rice slurry with dry materials such as starch and additives to form a semi-wet powder with a uniform component concentration, facilitating subsequent processing. Therefore, the mixing of dry and wet materials is one of the key steps.

[0003] Traditional mixing processes often employ batch-by-batch manual mixing or mechanical mixing equipment. For mechanical mixing equipment, existing technology discloses a dry-wet material mixing system, which includes a mixing tank. A dry material tank is fixedly connected to the inner wall of one through-hole, and a wet material tank is fixedly connected to the inner wall of the other through-hole. A crushing roller is inserted inside the dry material tank, and a humidification device is installed inside the wet material tank. One end of a mixing arm is inserted into the middle of the bottom wall of the mixing tank, and a ventilation and dehumidification device is fixedly connected to the outer wall of the mixing tank.

[0004] However, traditional mechanical mixing equipment has the following problems: First, insufficient mixing uniformity. When dry and wet powders come into contact, local lumps easily form. As with the existing technology mentioned above, which only uses the mixing arm to beat and disperse the materials, it is difficult to achieve micro-scale dispersion, resulting in uneven moisture distribution in the mixture. This not only affects the stability of subsequent extrusion molding processes but also leads to problems such as broken strands and a rough texture in the finished rice noodles. Second, poor equipment adaptability. Existing mixing equipment is mostly designed for single materials and cannot adapt to the mixing needs of different proportions (such as high starch content) or new functional additives (such as dietary fiber and trace calcium powder). Summary of the Invention

[0005] To address the problem of uneven mixing of dry and wet materials in the prior art, this invention provides a dry and wet material mixer for rice noodle processing, which can achieve mixing at the microscale, making the materials more uniform.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A dry and wet material mixer for rice noodle processing includes a frame, a rotary drive assembly, a stirring assembly, and a stirring box with a stirring chamber. The rotary drive assembly is mounted on the frame and drives the stirring assembly to rotate. The stirring assembly includes a rotating shaft, a first helical ribbon, and a second helical ribbon. The rotating shaft is rotatably connected to the stirring box and is also connected to the power output end of the rotary drive assembly. Both the first and second helical ribbons are spirally wound around the outside of the rotating shaft and maintain a distance from the outer surface of the rotating shaft. The rotation direction of the first helical ribbon is opposite to that of the second helical ribbon, and their pitches are different.

[0008] In the above technical solution, wet rice cakes made from pressed rice paste are fed into a mixing chamber along with dry starch. A rotary drive assembly then drives a rotating shaft to rotate at high speed, thereby causing the first and second spiral ribbons to rotate at high speed. During this process, the first and second spiral ribbons generate an efficient crossflow effect and radial throwing motion of the wet and dry materials within the mixing chamber, forcing the wet and dry materials to exchange rapidly in the axial and radial directions of the rotating shaft. It can be understood that the smaller the pitch and the smaller the helix angle, the stronger the radial throwing force of the spiral ribbon on the material, and the slower the axial movement speed of the material when pushed by the spiral ribbon. Conversely, the larger the pitch and the larger the helix angle, the weaker the radial throwing force of the spiral ribbon on the material, and the faster the axial movement speed of the material when pushed by the spiral ribbon. The first and second spiral ribbons have different pitches. The material is subjected to strong radial diffusion (small pitch) and strong axial convection (large pitch) in the mixing chamber at the same time, forming an interlaced flow field. This forces the rice flour clumps to be pulled in different directions, which can more effectively break up the rice flour clumps, thereby further improving the uniformity of the material and achieving microscopic uniformity of moisture and powder.

[0009] When the pitch difference between the first and second spiral ribbons is too large, it can cause excessive material accumulation on one side of the mixing chamber, resulting in excessively long mixing time and low mixing efficiency. Therefore, preferably, the pitch of the first spiral ribbon is between 0.5 and 1 times the pitch of the second spiral ribbon, excluding 0.5 and 1 times; or the pitch of the second spiral ribbon is between 0.5 and 1 times the pitch of the first spiral ribbon, excluding 0.5 and 1 times. Within this pitch difference range, mixing efficiency can be ensured while avoiding excessive material accumulation on one side of the mixing chamber, thus balancing the mixing of materials in both the axial and radial directions.

[0010] Preferably, multiple shearing rods are provided between the first and second spiral ribbons, with the axis of each shearing rod perpendicular to the axis of the rotating shaft. The two ends of each shearing rod are connected to the first and second spiral ribbons, respectively. During the rotation of the shaft, the shearing rods continuously tap and shear the rice flour clumps, thereby quickly breaking them up and improving mixing efficiency and uniformity.

[0011] Preferably, the mixing tank is provided with an auxiliary material addition port, a feed inlet, and a discharge port, all of which are connected to the mixing chamber. Materials enter the mixing chamber through the feed inlet, while calcium or other nutrients can enter through the auxiliary material addition port. The resulting mixture flows out through the discharge port.

[0012] Preferably, the auxiliary ingredient addition port is equipped with an atomizing nozzle. The amount of nutrients (such as calcium) and food additives added to rice noodles is relatively small, generally accounting for slightly less than 0%. Direct addition makes it difficult to accurately control the dosage and ensure even diffusion. With the atomizing nozzle, the nutrients or food additives can be dissolved in water first to obtain a solution. This solution is then sprayed into the mixing chamber through the atomizing nozzle. This not only facilitates accurate control of the added nutrients or food additives but also allows these food ingredients to fully blend with the dry and wet materials, resulting in a more uniform mixture.

[0013] Preferably, the mixing tank includes a tank body and a top cover. One end of the top cover is rotatably connected to the tank body, and the other end is detachably connected to the tank body. The tank body and the top cover form the mixing chamber. The feed inlet and the auxiliary material addition inlet are both located on the top cover. The openable and closable top cover allows for easy inspection of the mixing chamber by staff in case of abnormal discharge, and also facilitates cleaning of the mixing chamber.

[0014] Preferably, the feed inlet has at least two inlets. One feed inlet is used for feeding wet material, and the other feed inlet is used for feeding dry material. This facilitates the management of feeding dry and wet materials and reduces the risk of mold growth on the inner wall of a single feed inlet due to alternating wet and dry adhesion.

[0015] Preferably, the bottom of the mixing tank is provided with an arc-shaped guide section, and the discharge port is located at the bottom end of the arc-shaped guide section. The arc-shaped guide section can guide the mixed material to accumulate at the bottom end of the arc-shaped guide section, and then discharge it through the discharge port, reducing the residue of material in the mixing chamber.

[0016] Preferably, the rotary drive assembly includes a motor, a drive wheel, a driven wheel, and a synchronous belt surrounding the drive wheel and the driven wheel. A support plate is provided on the frame, located below the mixing tank. The motor is mounted on the support plate, and its output shaft is connected to the drive wheel. The driven wheel is coaxially and fixedly connected to the rotating shaft. The motor drives the drive wheel to rotate, which in turn drives the synchronous belt to rotate, which in turn drives the driven wheel to rotate. The driven wheel then drives the rotating shaft to rotate, thus achieving the rotary drive function. Providing a support plate below the mixing tank to house the motor allows for a more compact machine structure, saving space.

[0017] Preferably, the stirring assembly further includes a first ball bearing and a second ball bearing with coincident axes. A first bearing seat and a second bearing seat are respectively provided on the outer sides of the stirring tank. The first ball bearing and the second ball bearing are respectively mounted on the first bearing seat and the second bearing seat. The rotating shaft is simultaneously connected to the inner rings of the first ball bearing and the second ball bearing. The first ball bearing and the second ball bearing support the rotating shaft, ensuring smooth rotation.

[0018] The beneficial effects of this utility model are:

[0019] 1. The first and second spiral ribbons are set with opposite directions of rotation. The first and second spiral ribbons can generate a highly efficient crossflow effect and radial throwing motion of dry and wet materials in the mixing chamber, forcing the dry and wet materials to exchange rapidly in the axial and radial directions of the rotating shaft. At the same time, the first and second spiral ribbons have different pitches, which can make the materials in the mixing chamber be subjected to strong radial diffusion and strong axial convection at the same time, forming an interlaced flow field. This forces the agglomerated clumps to be pulled in different directions, which can more effectively break up the rice flour clumps, thereby further improving the uniformity of the materials and achieving microscopic uniformity of moisture and powder.

[0020] 2. A shearing rod is set between the first and second spiral ribbons. The shearing rod can continuously tap and shear the rice flour clumps, thereby quickly breaking down the rice flour clumps and improving mixing efficiency and uniformity.

[0021] The mixing tank is equipped with an auxiliary material addition port, which is equipped with an atomizing nozzle. After passing through the atomizing nozzle, the solution of nutrients or food additives can be sprayed into the mixing chamber. This not only helps to accurately control the amount of nutrients or food additives added, but also allows these food ingredients to be fully blended with dry and wet materials, resulting in a more uniform mixture.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0029] Example 1

[0030] This embodiment is the first embodiment of a dry and wet material mixing machine for rice noodle processing, combined with... Figures 1 to 3 As shown, it includes a frame 1, a rotary drive assembly, a stirring assembly, and a stirring tank 2 with a stirring chamber 2011. The rotary drive assembly is mounted on the frame 1 to drive the stirring assembly to rotate. The stirring assembly includes a rotating shaft 3, a first helical ribbon 4, and a second helical ribbon 5. The rotating shaft 3 is rotatably connected to the stirring tank 2 and is connected to the power output end of the rotary drive assembly. The first helical ribbon 4 and the second helical ribbon 5 are both spirally wound around the outside of the rotating shaft 3 and maintain a distance from the outer surface of the rotating shaft 3. The rotation direction of the first helical ribbon 4 is opposite to that of the second helical ribbon 5, and their pitches are different.

[0031] When the pitch difference between the first spiral ribbon 4 and the second spiral ribbon 5 is too large, it will cause excessive accumulation of material on one side of the mixing chamber 2011, resulting in excessively long mixing time and low mixing efficiency. Therefore, the pitch of the first spiral ribbon 4 is further 0.8 times that of the second spiral ribbon 5. This pitch difference can ensure mixing efficiency while avoiding excessive accumulation of material on one side of the mixing chamber 2011, thus balancing the mixing of material in both the axial and radial directions.

[0032] Specifically, the rotary drive assembly includes a motor 7, a drive wheel 8, a driven wheel 10, and a synchronous belt 9 surrounding the drive wheel 8 and the driven wheel 10. The motor 7 is a three-phase asynchronous motor equipped with a frequency converter, allowing adjustment of its speed according to the material's moisture content. This satisfies the mixing requirements of dry and wet materials at different mixing stages and adapts to the mixing of various materials, expanding its application range. A support plate 101 is mounted on the frame 1, located below the mixing tank 2. The motor 7 is mounted on the support plate 101, with its output shaft connected to the drive wheel 8. The driven wheel 10 is coaxially and fixedly connected to the rotating shaft 3. The synchronous belt 9 is a V-belt, a common type in the prior art. The motor 7 drives the drive wheel 8 to rotate, which in turn drives the synchronous belt 9 to rotate. The synchronous belt 9 then drives the driven wheel 10 to rotate, which in turn drives the rotating shaft 3, thus achieving the rotary drive function. The support plate 101 located below the mixing tank 2 for housing the motor 7 allows for a more compact machine structure, saving space.

[0033] Furthermore, the stirring assembly also includes a first ball bearing 14 and a second ball bearing 15 with coincident axes. A first bearing seat 12 and a second bearing seat 13 are respectively provided on the outer sides of the stirring tank 2. The first ball bearing 14 and the second ball bearing 15 are respectively mounted on the first bearing seat 12 and the second bearing seat 13. Both ends of the rotating shaft 3 are connected to the inner rings of the first ball bearing 14 and the second ball bearing 15, respectively. The first ball bearing 14 and the second ball bearing 15 can support the rotating shaft 3, ensuring that the rotating shaft 3 can rotate smoothly.

[0034] The working principle or workflow of this embodiment is as follows: Wet rice cakes, made from pressed rice paste, are fed into the mixing chamber 2011 along with dry starch. Then, a rotary drive assembly drives the rotating shaft 3 to rotate at high speed, thereby causing the first spiral ribbon 4 and the second spiral ribbon 5 to rotate at high speed. During this process, the first spiral ribbon 4 and the second spiral ribbon 5 generate an efficient crossflow effect and radial throwing motion of the dry and wet materials within the mixing chamber 2011, forcing the dry and wet materials to exchange rapidly in the axial and radial directions of the rotating shaft 3. It can be understood that the smaller the pitch and the smaller the helix angle, the stronger the radial throwing force of the spiral ribbon on the material, and the slower the axial movement speed of the material when the spiral ribbon pushes it. Conversely, the larger the pitch and the larger the helix angle, the weaker the radial throwing force of the spiral ribbon on the material, and the faster the axial movement speed of the material when the spiral ribbon pushes it. Within the mixing chamber 2011, the material is simultaneously subjected to strong radial diffusion (small pitch) and strong axial convection (large pitch), forming an interlaced flow field. This forces the agglomerated clumps to be pulled in different directions, which can more effectively break up the rice flour clumps, thereby further improving the uniformity of the material and achieving microscopic uniformity of moisture and powder.

[0035] The beneficial effects of this embodiment are as follows: By setting up a first spiral ribbon and a second spiral ribbon with opposite directions of rotation, the first and second spiral ribbons can generate an efficient crossflow effect and radial throwing motion of dry and wet materials in the mixing chamber, forcing the dry and wet materials to exchange rapidly in the axial and radial directions of the rotating shaft; at the same time, the first and second spiral ribbons have different pitches, which can make the materials in the mixing chamber simultaneously subjected to strong radial diffusion and strong axial convection, forming an interlaced flow field, forcing the agglomerated clumps to be pulled in different directions, which can more effectively break up the rice flour clumps, thereby further improving the uniformity of the materials and achieving microscopic uniformity of moisture and powder.

[0036] Example 2

[0037] This embodiment is a second embodiment of a dry and wet material mixing machine for rice noodle processing. This embodiment is similar to Embodiment 1, except that, as shown in the following... Figure 1 As shown, multiple shearing rods 6 are provided between the first spiral ribbon 4 and the second spiral ribbon 5. The axis of the shearing rods 6 is perpendicular to the axis of the rotating shaft 3. All shearing rods 6 penetrate the rotating shaft 3, and their two ends are connected to the first spiral ribbon 4 and the second spiral ribbon 5, respectively. During the rotation of the rotating shaft 3, the shearing rods 6 continuously tap and shear the rice flour clumps, thereby quickly breaking down the rice flour clumps and improving mixing efficiency and uniformity.

[0038] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.

[0039] Example 3

[0040] This embodiment is the third embodiment of a dry and wet material mixing machine for rice noodle processing. This embodiment is similar to embodiment 2, except that it combines... Figures 1 to 3As shown, the mixing tank 2 is equipped with an auxiliary material addition port 2022, a feed port 2021, and a discharge port 2012, all of which are connected to the mixing chamber 2011. Materials enter the mixing chamber 2011 through the feed port 2021, while calcium or other nutrients can enter through the auxiliary material addition port 2022. The resulting mixture flows out through the discharge port 2012.

[0041] Furthermore, an atomizing nozzle 11 is installed on the auxiliary material addition port 2022. The atomizing nozzle 11 is a pressure-type atomizing nozzle of existing technology, and its specific structure will not be described in detail. The amount of nutrients (such as calcium) and food additives added to rice noodles is relatively small, generally accounting for a percentage of slightly less than 0%. Direct addition makes it difficult to accurately control the dosage and to achieve uniform diffusion. With the atomizing nozzle 11 installed, the nutrients or food additives can be dissolved in water to obtain a solution. The solution is then sprayed into the mixing chamber 2011 through the atomizing nozzle 11. This not only helps to accurately control the amount of nutrients or food additives added, but also allows these food ingredients to be fully blended with the dry and wet materials, resulting in a more uniform mixture.

[0042] Furthermore, the mixing tank 2 includes a tank body 201 and a top cover 202. One end of the top cover 202 is rotatably connected to the tank body 201, and the other end is detachably connected to the tank body 201. The tank body 201 and the top cover 202 form a mixing chamber 2011. The feed inlet 2021 and the auxiliary material addition inlet 2022 are both located on the top cover 202. The top cover 202, which can be opened and closed, allows staff to easily open it to inspect the inside of the mixing chamber 2011 in case of abnormal discharge, and also facilitates cleaning of the inside of the mixing chamber 2011.

[0043] Furthermore, there are two feed inlets 2021. One feed inlet 2021 is used for feeding wet materials, and the other feed inlet 2021 is used for feeding dry materials. This facilitates the management of feeding dry and wet materials and reduces the risk of mold growth on the inner wall of a single feed inlet 2021 due to the alternating adhesion of wet and dry materials.

[0044] Furthermore, the bottom of the mixing tank 2 is provided with an arc-shaped guide section 2013, and the discharge port 2012 is located at the bottom end of the arc-shaped guide section 2013. The arc-shaped guide section 2013 can guide the mixed material to accumulate at the bottom end of the arc-shaped guide section 2013, and then discharge it through the discharge port 2012, reducing the residue of material in the mixing chamber 2011.

[0045] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 2.

[0046] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description, and it is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
