Description

Technical Field

[0001] This utility model relates to the field of grain soaking, specifically a grain soaking device for reducing grain waste. Background Technology

[0002] A grain soaking device is a specialized piece of equipment used for pre-processing of grains (such as rice, corn, wheat, etc.). It softens the grains by absorbing water through precise control of water temperature and time, making them easier to dehull, crush, or ferment. It typically consists of a soaking tank, a stirring system, and a control system. It also has the functions of cleaning and removing impurities and is widely used in brewing, starch processing, and food manufacturing. It can improve processing efficiency and enhance the quality of finished products.

[0003] The existing grain soaking equipment often generates strong eddies during the stirring process, causing the grains to tumble violently in the high-speed water flow, colliding and rubbing against each other. This violent movement not only damages the surface structure of the grains and increases mechanical damage between particles, but also causes some grains to break due to collision, especially brittle varieties such as rice or sorghum. This affects the subsequent processing effect, resulting in a poorer taste of the final product, a lower yield, and reduced economic benefits.

[0004] In summary, in order to reduce mechanical damage to grains during soaking and improve the integrity and uniformity of soaking, it is necessary to solve the problem of strong eddies generated by existing stirring structures, so that grains can absorb water evenly in a mild and stable water flow environment, thereby reducing the breakage rate and improving the taste and yield of the final product. Utility Model Content

[0005] The purpose of this invention is to provide a grain soaking device that reduces grain waste. By replacing the rotating stirring structure with a stirring rod that swings within a certain range, eddies can be avoided, the integrity of the grain can be improved, and the problems mentioned in the background art can be solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grain soaking device for reducing grain waste, comprising a soaking tank, a support frame on the soaking tank, a fixed frame fixed on the support frame, a first U-shaped seat fixed inside the fixed frame, a cross-shaped connecting seat rotatably connected to the first U-shaped seat, a second U-shaped seat rotatably connected to the outside of the cross-shaped connecting seat, a fixed seat fixed on the second U-shaped seat, a connecting rod mounted on the fixed seat, a rotating shaft rotatably connected to the fixed frame, a connecting piece mounted at the bottom of the rotating shaft, a positioning ball fixed at the end of the connecting rod, the positioning ball rotatably connected to the connecting piece, a rotating mechanism for rotating the rotating shaft on the fixed frame, multiple fixed rods mounted on the outside of the fixed seat, a stirring rod fixed on the fixed rod, multiple conical blocks mounted on the outside of the stirring rod, a surging mechanism for assisting in turning the grain at the bottom of the soaking tank on the outside, and a drainage component on the outside of the soaking tank.

[0007] Preferably, the rotating mechanism includes a rotating component and a protective component, both of which are disposed on the top of the fixed frame. The rotating component is used to drive the rotating shaft to rotate, and the protective component is used to shield the rotating component.

[0008] Preferably, the rotating assembly includes a fixed frame fixed to the top of the fixed frame, a drive motor fixed to the fixed frame, a drive gear mounted on the output end of the drive motor, and a driven gear fixed to the outside of the rotating shaft. The drive gear meshes with the driven gear, and the drive motor is used to drive the drive gear to rotate.

[0009] Preferably, the protective component includes a positioning frame fixed to the top of the fixed frame, a protective shell disposed on the positioning frame, and a heat dissipation groove formed on the protective shell, wherein the protective shell and the positioning frame are fixed by bolts.

[0010] Preferably, the agitation mechanism includes an air blowing assembly and a partition assembly. The air blowing assembly is disposed on the soaking tank, and the partition assembly is disposed at the air outlet of the air blowing assembly. The air blowing assembly is used to assist in agitating the grains inside the soaking tank, and the partition assembly is used to prevent the grains from entering the air outlet of the air blowing assembly.

[0011] Preferably, the air blowing assembly includes multiple air jets fixed to the outside of the soaking tank, a connecting pipe connected to the outside of the multiple air jets, and an interface fixed to the connecting pipe, the interface being connected to an external air pump.

[0012] Preferably, the partition assembly includes a conical shell disposed at the outlet of the jet pipe and a partition mesh fixed at the port of the conical shell, wherein the conical shell is threadedly connected to the jet pipe.

[0013] Preferably, the drainage assembly includes an electric push rod fixed to the outside of the soaking tank, a connecting frame installed at the output end of the electric push rod, a cylinder fixed to the connecting frame, a water filter hole opened on the outside of the cylinder, and a rubber sheet fixed to the inside of the cylinder. The cylinder slides in contact with the inner wall of the water outlet pipe at the bottom of the soaking tank, and the electric push rod is used to drive the cylinder to rise and fall.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention significantly improves the stirring effect during grain soaking by replacing the traditional high-speed rotating stirring structure with a reciprocating stirring rod within a certain angle. The reciprocating stirring rod generates gentle water flow disturbance, allowing the grains to tumble evenly in the soaking tank. This avoids violent collisions caused by strong eddies formed by rotation. This gentle stirring method effectively reduces friction and impact between grains, minimizing grain breakage. It is especially protective for brittle varieties (such as rice and sorghum), thereby improving the quality of subsequent processing and providing higher-quality raw materials for industries such as brewing and starch processing.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] Refer to the instruction manual appendix Figures 1 to 6A grain soaking device for reducing food waste includes a soaking tank 1, a support 2 on the soaking tank 1, a fixed frame 3 fixed on the support 2, a first U-shaped seat 4 fixed inside the fixed frame 3, a cross-shaped connecting seat 5 rotatably connected to the first U-shaped seat 4, a second U-shaped seat 6 rotatably connected to the outside of the cross-shaped connecting seat 5, a fixed seat 7 fixed on the second U-shaped seat 6, a connecting rod 8 mounted on the fixed seat 7, a rotating shaft 9 rotatably connected to the fixed frame 3, a connecting piece 10 mounted at the bottom of the rotating shaft 9, a positioning ball 11 fixed at the end of the connecting rod 8, the positioning ball 11 rotatably connected to the connecting piece 10, a rotating mechanism for rotating the rotating shaft 9 on the fixed frame 3, multiple fixed rods 13 mounted on the outside of the fixed seat 7, a stirring rod 14 fixed on the fixed rod 13, multiple conical blocks 15 mounted on the outside of the stirring rod 14, a surging mechanism for assisting in turning the grain at the bottom of the soaking tank 1 on the outside, and a drainage component on the outside of the soaking tank 1.

[0025] It should be noted that the rotation of the shaft 9, through the connection between the connecting piece 10 and the positioning ball 11, drives the inclined connecting rod 8 to move. With the multi-directional rotational freedom provided by the cross-shaped connecting seat 5, the first U-shaped seat 4 and the second U-shaped seat 6, the reciprocating motion of the connecting rod 8 is converted into the swing of the fixed seat 7. The fixed seat 7 drives the fixed rod 13 and the stirring rod 14 on its outer side to swing back and forth within a limited angle. This swing mode avoids the strong eddies generated by traditional rotational stirring, so that the grains are turned more gently and evenly in the soaking tank 1, effectively reducing the damage rate of the grains caused by violent collision and friction, and improving the integrity and soaking uniformity of the grains.

[0026] Refer to the instruction manual appendix Figures 2 to 4 The rotating mechanism includes a rotating component and a protective component. Both the rotating component and the protective component are located on the top of the fixed frame 3. The rotating component is used to drive the rotating shaft 9 to rotate, and the protective component is used to shield the rotating component.

[0027] It should be noted that the rotating assembly is used to provide the power and motion conversion required to drive the rotating shaft 9 to rotate, while the protective assembly is used to protect the core components of the rotating assembly from the influence of the external environment (such as dust and moisture), ensuring the reliability and service life of operation.

[0028] Refer to the instruction manual appendix Figures 2 to 4 The rotating assembly includes a fixed frame 121 fixed to the top of the fixed frame 3, a drive motor 122 fixed to the fixed frame 121, a drive gear 123 installed at the output end of the drive motor 122, and a driven gear 124 fixed to the outside of the rotating shaft 9. The drive gear 123 meshes with the driven gear 124, and the drive motor 122 is used to drive the drive gear 123 to rotate.

[0029] It should be noted that the drive motor 122 drives the drive gear 123 to rotate. The drive gear 123, through meshing with the driven gear 124, drives the driven gear 124 fixed on the rotating shaft 9 and the rotating shaft 9 to rotate synchronously.

[0030] Refer to the instruction manual appendix Figure 2 The protective assembly includes a positioning frame 125 fixed to the top of the fixed frame 3, a protective shell 126 disposed on the positioning frame 125, and a heat dissipation groove 127 formed on the protective shell 126. The protective shell 126 is fixed to the positioning frame 125 by bolts.

[0031] It should be noted that the positioning frame 125 is used to fix and support the protective shell 126, which covers the rotating assembly to form a protective barrier, and the heat dissipation groove 127 is used to promote internal air circulation and heat dissipation.

[0032] Refer to the instruction manual appendix Figure 1 and Figure 5 The surging mechanism includes an air blowing component and a partition component. The air blowing component is installed on the soaking tank 1, and the partition component is installed at the air outlet of the air blowing component. The air blowing component is used to assist in stirring the grains inside the soaking tank 1, and the partition component is used to prevent the grains from entering the air outlet of the air blowing component.

[0033] It should be noted that the air blowing assembly is responsible for generating and delivering airflow, while the baffle assembly is located at the air outlet of the air blowing assembly. Its function is to prevent grain particles from entering and clogging the air outlet.

[0034] Refer to the instruction manual appendix Figure 1 and Figure 5 The air blowing assembly includes multiple air jet pipes 161 fixed to the outside of the soaking tank 1, a connecting pipe 162 connected to the outside of the multiple air jet pipes 161, and an interface 163 fixed to the connecting pipe 162. The interface 163 is connected to an external air pump.

[0035] It should be noted that when the external air pump is started, the high-speed airflow is distributed to multiple jet pipes 161 through the connecting pipe 162, and finally the airflow is sprayed into the bottom area of ​​the soaking tank 1 to help stir the grains deposited at the bottom, promote their turning and even soaking.

[0036] Refer to the instruction manual appendix Figure 5 The partition assembly includes a conical shell 164 disposed at the outlet of the jet pipe 161 and a partition mesh 165 fixed at the port of the conical shell 164. The conical shell 164 is threadedly connected to the jet pipe 161.

[0037] It should be noted that the conical shell 164 covers the air outlet, and the baffle net 165 covers its port, allowing airflow to pass through but effectively preventing grain particles from entering the jet pipe 161 and causing blockage.

[0038] Refer to the instruction manual appendix Figure 1 and Figure 6 The drainage assembly includes an electric push rod 171 fixed to the outside of the soaking tank 1, a connecting frame 172 installed at the output end of the electric push rod 171, a cylinder 173 fixed on the connecting frame 172, a filter hole 174 opened on the outside of the cylinder 173, and a rubber sheet 175 fixed on the inside of the cylinder 173. The cylinder 173 slides against the inner wall of the water outlet pipe at the bottom of the soaking tank 1. The electric push rod 171 is used to drive the cylinder 173 to rise and fall.

[0039] It should be noted that the electric push rod 171 drives the connecting frame 172 and the cylinder 173 to rise and fall. When the cylinder 173 descends, its outer filter hole 174 is blocked by the inner wall of the water outlet pipe at the bottom of the soaking tank 1 (rubber sheet 175 assists in the sealing), preventing drainage. When the cylinder 173 rises, the filter hole 174 is exposed above the water outlet pipe, and the soaking water can enter the inside of the cylinder 173 through the filter hole 174 and then be discharged through the water outlet pipe, realizing the drainage function. The rubber sheet 175 helps to improve the sealing between the cylinder 173 and the inner wall of the water outlet pipe. During discharge, the cylinder 173 descends until it is separated from the water outlet pipe, and the grain is received by the external material frame and guide plate.

[0040] Working principle: The drive motor 122 starts, driving the drive gear 123 to rotate. Through meshing with the driven gear 124, it drives the rotating shaft 9 to rotate. The connecting piece 10 at the bottom of the rotating shaft 9 rotates accordingly. Through the positioning ball 11 connected to it, it drives the inclined connecting rod 8 to move. The reciprocating motion of the connecting rod 8 is transmitted through the cross-shaped connecting seat 5, the first U-shaped seat 4, and the second U-shaped seat 6, and is converted into the reciprocating oscillation of the fixed seat 7 within a limited angle. The fixed seat 7 drives the multiple fixed rods 13 and the stirring rod 14 on its outer side to swing synchronously. The conical block 15 on the stirring rod 14 gently turns the grain in the soaking tank 1. At the same time, the outer... The air pump delivers airflow to multiple jet pipes 161 through interface 163 and connecting pipe 162. The airflow is ejected from the jet pipes 161 to assist in stirring the grain at the bottom. During drainage, the electric push rod 171 pushes the connecting frame 172 and cylinder 173 to rise, so that the filter hole 174 on the outside of the cylinder 173 is exposed above the water outlet pipe at the bottom of the soaking tank 1. The soaking water flows into the cylinder 173 through the filter hole 174 and is then discharged. At the same time, the electric push rod 171 reciprocates, causing the cylinder 173 to continuously rise, thereby preventing the grain from accumulating in the water outlet pipe. During discharge, the cylinder 173 is pushed away from the water outlet pipe by the electric push rod 171, and the grain falls into the outer material frame.

The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art.
