Meal replacement food preparation pulverization and grinding process and device

Abstract

This invention relates to a grinding and pulverizing process and apparatus for preparing meal replacement foods, belonging to the field of food grinding technology. The apparatus includes a grinding jar, a grinding mechanism, a roller brush mechanism, a cutting and feeding mechanism, and a striking mechanism. Through the coordinated use of the roller brush mechanism and the grinding mechanism, when the rotating grinding disc within the grinding mechanism grinds the food raw materials, it drives the roller brush mechanism to work. The first spiral brush rotates on its own axis while revolving around the central axis, which in turn drives the second spiral brush to rotate. This allows the first spiral brush to brush the powdery food raw materials adhering to the gap between the rotating grinding disc and the bottom grinding disc, and the second spiral brush to brush the powdery food raw materials adhering to the gap between the rotating grinding disc and the top grinding disc. This prevents the accumulation and adhesion of powdery food raw materials, ensuring grinding efficiency and preventing contamination of subsequent raw material grinding, thus guaranteeing the quality of the prepared meal replacement food.

Description

Technical Field

[0001] This invention belongs to the field of food grinding technology, specifically relating to a grinding and pulverizing process and apparatus for preparing meal replacement foods. Background Technology

[0002] Meal replacement food grinding is the process of turning raw materials into powder through grinding technology. This is a key step in the production of meal replacement foods. The purpose of grinding is to refine the raw materials, making them easier for the human body to digest and absorb, while also improving the taste and enhancing the eating experience. Common equipment used in the grinding process of meal replacement foods includes crushers and grinders.

[0003] A search revealed Chinese invention patent application CN202410583428.7, which describes a method for preparing meal replacement powder and a pulverizing device. This invention relates to the field of meal replacement powder production technology and includes the following steps: feeding grain raw materials into a pulverizing device for pulverization; during pulverization, the pulverizing device uses internal circulating air to assist the grains in moving towards the discharge direction, preventing grain blockage; heating the circulating airflow to dry the grains; collecting the pulverized grains and mixing them in a proportion to obtain the meal replacement powder. This invention utilizes a receiving ring to achieve friction and pulverization of the grains during the rotation of the pulverizing disc and the movement of the grains. A guiding cavity allows the grains to move continuously along a curved path, increasing the contact probability between the grains and the pulverizing disc, thereby improving pulverization efficiency. A guide cavity and guide holes are opened on the receiving ring, and the airflow from the guide holes assists in pushing and feeding the grains, preventing grain blockage.

[0004] However, during the grinding process of raw materials for producing meal replacement foods, the grinding of raw materials by the grinding discs will cause the temperature between the grinding discs to rise, accelerating the aging and wear of the grinding discs. At the same time, the raw materials will stick to the grinding discs under the action of grinding, which will reduce the grinding efficiency of the grinding discs. Moreover, it is difficult to clean the powdery food raw materials stuck between the grinding discs, increasing the labor burden. Based on this, a grinding process and device for preparing meal replacement foods is proposed. Summary of the Invention

[0019] As a further optimization of the present invention, a handle is fixedly connected to the outer side of the mounting cage, an air inlet pipe is fixedly connected inside the mounting cage, an air pump is fixedly connected to the air inlet end of the air inlet pipe, an upper air outlet and a lower air outlet are respectively opened at the top and bottom of the air inlet pipe, a plug pipe is fixedly connected to the side wall of the mounting cage, a dehumidifying plate is installed inside the plug pipe, the plug pipe is connected to the inside of the air inlet pipe, the plug pipe is sealed and plugged into the bottom grinding disc, and a connecting pipe is fixedly connected to the side wall of the rotating ring, and the connecting pipe is fixedly connected to the rotating grinding disc.

[0020] A grinding and pulverizing process for preparing meal replacement foods includes the following steps:

[0021] Step 1: Add the food ingredients to be ground into the grinding jar through the feeding hopper;

[0022] Step 2: Start the motor to make the hollow shaft drive the rotating grinding disc to rotate, and grind the food raw materials through the top grinding disc, rotating grinding disc and bottom grinding disc;

[0023] Step 3: When the motor starts, the air pump starts simultaneously, so that the air pump draws outside air into the installation cage through the air inlet pipe, and injects it into the top grinding disc, bottom grinding disc and rotating grinding disc through the upper air outlet, lower air outlet and plug pipe respectively.

[0025] Step 5: During this process, the hollow rotating shaft drives the brush rod to rotate along the upper surface of the filter screen, so that the powdered food raw materials with the required particle size fall through the filter screen onto the top of the guide plate;

[0026] Step Six: During the rotation of the hollow rotating shaft, the first wedge block pushes the second wedge block back and forth, causing the striking head to repeatedly strike the guide plate under the action of the return spring, so that the powdered food raw materials obtained from grinding move towards the discharge gate.

[0027] Step 7: After grinding, open the discharge door to collect the powdered food raw materials obtained from grinding, and open the cleaning door to clean the large particles of raw materials accumulated on the top of the filter screen.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. This invention utilizes the combined use of a roller brush mechanism and a grinding mechanism. When the rotating grinding disc within the grinding mechanism grinds the food ingredients, it drives the roller brush mechanism to revolve. Simultaneously, the first helical gear within the roller brush mechanism rotates under the action of the first helical gear ring, causing the first rotating rod to rotate the first spiral brush. The rotation of the ring, in turn, drives the second helical gear through the second helical gear ring, which in turn drives the second spiral brush through the second rotating rod. This allows the first spiral brush to roller brush the powdered food ingredients adhering to the gap between the rotating grinding disc and the bottom grinding disc, and the second spiral brush to roller brush the powdered food ingredients adhering to the gap between the rotating grinding disc and the top grinding disc. This prevents the accumulation and adhesion of powdered food ingredients, ensuring grinding efficiency and preventing contamination of subsequent grinding processes, thus guaranteeing the quality of the prepared meal replacement food.

[0030] 2. The present invention enables the cutting and feeding mechanism to cut the food raw materials entering between the top grinding disc and the rotating grinding disc, thereby initially reducing the particle size of the food raw materials, which facilitates the grinding of the food raw materials by the top grinding disc and the rotating grinding disc, and improves the grinding efficiency.

[0031] 3. This invention, through the combined use of an air pump, air inlet pipe, upper air outlet, lower air outlet, connector pipe, and connecting pipe, draws in outside air and introduces it into the top, bottom, and rotating grinding discs of the grinding mechanism. This cools the top, bottom, and rotating grinding discs, preventing excessively high temperatures during grinding that could accelerate wear and extending their service life. Furthermore, it reduces the probability of oxidation of powdered food ingredients, thus preventing the loss of nutritional value and ensuring the nutritional value of the produced meal replacement food.

[0032] 4. This invention uses a brush rod to intermittently blow air onto the upper surface of the filter screen. This avoids the accumulation of powdered food ingredients on the top of the filter screen, which would reduce the efficiency of filtration and ensure the filtration efficiency of the filter screen. On the other hand, the blown air passes between the bottom grinding disc and the rotating grinding disc, as well as between the rotating grinding disc and the top grinding disc, further reducing the probability of powdered food ingredients sticking to the grinding discs, thereby improving the grinding efficiency of the food ingredients.

Detailed Implementation

[0048] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0049] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, a meal replacement food preparation grinding and pulverizing device includes a grinding tank 1 and a guide plate 4 fixedly connected inside the grinding tank 1. A discharge door 2 is installed on the side wall of the grinding tank 1, and a feeding hopper 3 is installed on the top of the grinding tank 1. An installation cage 5 is installed on the side wall of the grinding tank 1, and a handle 11 is fixedly connected to the outside of the installation cage 5. An air inlet pipe 12 is fixedly connected inside the installation cage 5, and an air pump 13 is fixedly connected to the air inlet end of the air inlet pipe 12. An upper air outlet 14 and a lower air outlet 15 are respectively opened at the top and bottom of the air inlet pipe 12. A connecting pipe 16 is fixedly connected to the side wall of the installation cage 5, and the connecting pipe 16 communicates with the inside of the air inlet pipe 12. An installation is installed inside the connecting pipe 16. The grinding tank 1 includes a dehumidifying plate filled with desiccant. A handle 11 facilitates the removal of the mounting cage 5 for easy replacement of the dehumidifying plate installed in the insertion pipe 16. A cleaning door 6 is installed on the side wall of the grinding tank 1. The grinding tank 1 also includes a grinding mechanism 7 installed in the middle of the grinding tank 1. The grinding mechanism 7 is used for coarse and fine grinding of food raw materials. The grinding mechanism 7 includes a top grinding disc 703, a bottom grinding disc 704, and a rotating grinding disc 705. A second exhaust pipe 1012 is fixedly connected to the top of the grinding tank 1, and the second exhaust pipe 1012 is fixedly connected to the top grinding disc 703. A first exhaust pipe 101 is fixedly connected to the bottom of the bottom grinding disc 704. 1. The first exhaust pipe 1011 passes through the grinding jar 1 in a sealed manner. The insertion pipe 16 is sealed and inserted into the bottom grinding disc 704. The distance between the top grinding disc 703 and the rotating grinding disc 705 is greater than the distance between the rotating grinding disc 705 and the bottom grinding disc 704. The food raw materials are coarsely ground between the top grinding disc 703 and the rotating grinding disc 705, and finely ground between the bottom grinding disc 704 and the rotating grinding disc 705. The top of the top grinding disc 703 is funnel-shaped to facilitate the entry of food raw materials between the top grinding disc 703 and the rotating grinding disc 705. The top grinding disc 703 and the bottom grinding disc 704 are fixedly connected inside the grinding jar 1. The grinding mechanism 7 is fixedly connected to the grinding tank 1. The side wall of the grinding tank 1 is equipped with a mounting cage 5. The top grinding disc 703 and the bottom grinding disc 704 are both hollow. The rotating grinding disc 705 is located between the top grinding disc 703 and the bottom grinding disc 704. The rotating grinding disc 705 is also hollow. The grinding mechanism 7 also includes a motor 701 installed at the top center of the grinding tank 1. The output end of the motor 701 is fixedly connected to a hollow rotating shaft 702. The hollow rotating shaft 702 passes through the grinding tank 1 and is rotatably connected to the grinding tank 1. The hollow rotating shaft 702 passes through the guide plate 4 and is rotatably connected to the guide plate 4. The rotating grinding disc 705 is fixedly connected to the outer surface of the hollow rotating shaft 702.

[0050] In use, the food ingredients to be ground are added to the grinding tank 1 through the feeding hopper 3. Then, the motor 701 is started, causing the hollow rotating shaft 702 to drive the rotating grinding disc 705 to rotate. The food ingredients entering the grinding tank 1 will fall onto the top of the top grinding disc 703. Since the top of the top grinding disc 703 is funnel-shaped, the food ingredients will roll into the space between the top grinding disc 703 and the rotating grinding disc 705. At this time, the rotation of the rotating grinding disc 705 will coarsely grind the food ingredients that have entered the space between the top grinding disc 703 and the rotating grinding disc 705. The coarsely ground food ingredients will then enter the space between the rotating grinding disc 705 and the bottom grinding disc 704. At this time, the rotation of the rotating grinding disc 705 will finely grind the coarsely ground food ingredients that have entered the space between the rotating grinding disc 705 and the bottom grinding disc 704. The ground powdered food ingredients will fall onto the top of the guide plate 4. After the food ingredients are completely ground, the discharge door 2 can be opened to collect the obtained powdered food ingredients.

[0051] like Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 13 and Figure 14As shown, the grinding and pulverizing device further includes: a roller brush mechanism 8 installed within the grinding mechanism 7. The roller brush mechanism 8 is used to clean the rotating grinding disc 705 and the bottom grinding disc 704 and to transport the ground materials of food ingredients. This not only reduces the probability of powdered food ingredients adhering between the top grinding disc 703 and the rotating grinding disc 705, but also reduces the probability of adhering to the bottom grinding disc 704 and the rotating grinding disc 705, and also provides directional transport of the ground materials. The roller brush mechanism 8 includes a first roller brush groove 801 and a second roller brush groove 811. A first rotating rod 802 is rotatably connected to the bottom of the rotating grinding disc 705, and a first spiral brush 803 is fixedly connected to the outer surface of the first rotating rod 802. The outer surface of the first spiral brush 803 is in contact with the top of the bottom grinding disc 704. A second rotating rod 809 is rotatably connected to the bottom of the top grinding disc 703, and a second spiral brush 810 is fixedly connected to the outer surface of the second rotating rod 809. The surface of the roller brush mechanism 8 is in contact with the top of the rotating grinding disc 705. The roller brush mechanism 8 also includes a first helical gear 805 fixedly connected to the end of the first rotating rod 802. A rotating ring 804 is rotatably connected to the outer surface of the first rotating rod 802. A connecting pipe 17 is fixedly connected to the side wall of the rotating ring 804. The connecting pipe 17 is fixedly connected to the rotating grinding disc 705. The rotating ring 804 is rotatably connected to the top grinding disc 703 and the bottom grinding disc 704. A first helical gear ring 806 is fixedly connected to the top of the bottom grinding disc 704. 6 meshes with the first helical gear 805. The top of the rotating ring 804 is fixedly connected to the second helical gear ring 807. The end of the second rotating rod 809 is fixedly connected to the second helical gear 808, which meshes with the second helical gear ring 807. The other end of the second rotating rod 809 is fixedly connected to the third helical gear 812. The first rotating rod 802 passes through the rotating grinding disc 705 and is rotatably and sealed to the rotating grinding disc 705. The second rotating rod 809 passes through the top grinding disc 703 and is rotatably and sealed to the top grinding disc 703.

[0052] When the grinding disc 705 rotates, it drives the first rotating rod 802 to revolve, which in turn drives the rotating ring 804 to revolve. The revolve of the first rotating rod 802 drives the first helical gear 805 to move along the outer surface of the first helical gear ring 806, causing the first helical gear 805 to rotate during its movement. This, in turn, causes the first rotating rod 802 to rotate during its revolve, which in turn drives the first spiral brush 803 to rotate during its revolve. The spiral brush 803 then rolls and brushes the powdered food ingredients that are stuck between the rotating grinding disc 705 and the bottom grinding disc 704, preventing the powdered food ingredients from accumulating and sticking together, ensuring grinding efficiency, preventing the sticking of powdered food ingredients from contaminating the grinding of subsequent ingredients, and ensuring the quality of the prepared meal replacement food. During the revolve of the rotating ring 804, it drives the second helical gear ring 807 to revolve. During the revolution, the second helical gear 808 meshes with the second helical gear ring 807, causing the second helical gear 808 to drive the second rotating rod 809 to rotate, which in turn drives the second spiral brush 810 to rotate. This allows the second spiral brush 810 to brush the powdered raw materials stuck between the rotating grinding disc 705 and the top grinding disc 703, preventing the accumulation and adhesion of powdered food materials, ensuring grinding efficiency, preventing the adhesion of powdered food materials from contaminating the grinding of subsequent raw materials, and ensuring the quality of the prepared meal replacement food. Furthermore, since the first spiral brush 803 and the second spiral brush 810 are set in a spiral shape, and the spiral structure has a certain conveying function, it can further convey the powdered food materials, further reducing the probability of accumulation and adhesion of powdered food materials, thereby improving grinding efficiency.

[0053] When grinding begins, the air pump 13 is activated, drawing outside air into the intake pipe 12. The air is then divided into three streams through the upper outlet 14, lower outlet 15, and connector 16. The first stream enters the top grinding disc 703 to cool it, and the airflow absorbing the heat from the top grinding disc 703 is discharged through the second exhaust pipe 1012. The second stream enters the bottom grinding disc 704 to cool it, and the airflow absorbing the heat from the bottom grinding disc 704 is discharged through the first exhaust pipe 1011 and the connector 16. The third airflow, after being dried by the desiccant in the dehumidifying plate, will enter the space formed by the rotating ring 804, the top grinding disc 703, and the bottom grinding disc 704. The dried airflow entering the space formed by the top grinding disc 703 and the bottom grinding disc 704 will enter the rotating grinding disc 705 through the connecting pipe 17, thereby achieving the purpose of cooling the rotating grinding disc 705, avoiding excessively high temperatures during the grinding process that would accelerate the wear of the grinding disc, extending the service life of the grinding disc, and reducing the probability of oxidation of powdered food raw materials, which would cause the nutritional components of the powdered food raw materials to be ineffective, thus ensuring the nutritional value of the produced meal replacement food.

[0054] like Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 12 and Figure 14 As shown, the grinding and crushing device further includes: a cutting and conveying mechanism 9 installed in the middle of the top grinding disc 703 for cutting and conveying raw materials. The cutting and conveying mechanism 9 is used to cut and convey food raw materials to facilitate the grinding of food raw materials by the top grinding disc 703, the bottom grinding disc 704, and the rotating grinding disc 705. The cutting and conveying mechanism 9 includes a rotating sleeve 901 rotatably connected to the middle of the top grinding disc 703. A third helical tooth ring 902 is fixedly connected to the outer surface of the rotating sleeve 901. The third helical tooth ring 902 meshes with a third helical gear 812. A cutting rod 903 is fixedly connected inside the rotating sleeve 901. A spiral plate 904 is fixedly connected to the outer surface of the hollow rotating shaft 702. The spiral plate 904 has an opening on it. The grinding tank 1 has a slot 905 for the cutting rod 903 to pass through. A filter screen 1008 is fixedly connected to the inner surface of the grinding tank 1. A cleaning door 6 is located on the top of the filter screen 1008. A hollow rotating shaft 702 passes through the filter screen 1008 and is rotatably connected to the filter screen 1008. A brush rod 1009 is fixedly connected to the outer surface of the hollow rotating shaft 702. The brush rod 1009 is connected to the inside of the hollow rotating shaft 702. The brush rod 1009 is attached to the top of the filter screen 1008. The brush rod 1009 has bristles on the side facing the filter screen 1008. An air blowing hole 1010 is opened on the side wall of the brush rod 1009. The air blowing hole 1010 is located on the side of the rotating forward direction of the brush rod 1009.

[0055] During the process of raw materials entering between the top grinding disc 703 and the rotating grinding disc 705, the third helical gear 812 will rotate synchronously under the rotation of the second rotating rod 809, which in turn drives the rotating sleeve 901 to rotate through the third helical gear ring 902, causing the cutting rod 903 to revolve. At the same time, the rotation of the hollow rotating shaft 702 will drive the spiral plate 904 to rotate, so that the spiral plate 904 conveys the food raw materials. During the conveying process, the revolving cutting rod 903 will cut the food raw materials through the slot 905, initially reducing the particle size of the food raw materials, thereby facilitating the grinding of the food raw materials by the top grinding disc 703 and the rotating grinding disc 705, improving the grinding efficiency. The ground powdered food raw materials will fall on the top of the filter screen 1008, causing the brush rod 1009 to rotate along the top of the filter screen 1008 under the rotation of the hollow rotating shaft 702, avoiding the accumulation of powdered food raw materials on the top of the filter screen 1008. Accumulation of powdered food materials leads to low filtration efficiency of filter 1008 for powdered food materials. To ensure the filtration efficiency of filter 1008 for powdered food materials, the filtered powdered food materials will fall on the top of the guide plate 4. After the airflow enters the rotating grinding disc 705 and absorbs the temperature of the rotating grinding disc 705, it enters the brush rod 1009 through the hollow rotating shaft 702 and is blown towards the top of filter 1008 through the air blowing hole 1010, thus avoiding the accumulation of powdered food materials on the top of filter 1008. This also ensures the filtration efficiency of filter 1008 for powdered food materials. In addition, the blown air will also pass between the bottom grinding disc 704 and the rotating grinding disc 705, and between the rotating grinding disc 705 and the top grinding disc 703, further reducing the probability of powdered food materials sticking to the grinding discs, thereby improving the grinding efficiency of food materials.

[0056] like Figure 2 , Figure 6 , Figure 7 and Figure 9 As shown, the crushing and grinding device also includes: a striking mechanism 10 installed inside the grinding tank 1 for striking the guide plate 4. The striking mechanism 10 includes a fixed rod 1001 fixedly connected to the outer surface of the hollow rotating shaft 702. A first wedge block 1002 is fixedly connected to the free end of the fixed rod 1001. A fixed frame 1003 is fixedly connected inside the grinding tank 1. A connecting rod 1004 is slidably connected through the fixed frame 1003. A second wedge block 1005 and a striking head 1006 are fixedly connected to both ends of the connecting rod 1004, respectively. The striking head 1006 is made of rubber. The second wedge block 1005 and the first wedge block 1002 are adapted to each other. A return spring 1007 is sleeved on the outer surface of the connecting rod 1004. The two ends of the return spring 1007 are fixedly connected to the striking head 1006 and the fixed frame 1003, respectively.

[0057] When the hollow rotating shaft 702 rotates, it will drive the fixed rod 1001 to rotate, causing the first wedge block 1002 to intermittently push the second wedge block 1005 upward, which in turn pushes the striking head 1006 to strike the guide plate 4 through the connecting rod 1004, causing the guide plate 4 to vibrate, which facilitates the movement of the powdered food raw materials on the top of the guide plate 4 towards the location of the discharge gate 2, making it easier to discharge and collect the powdered food raw materials. When the first wedge block 1002 disengages from the location of the second wedge block 1005, the striking head 1006 will be reset under the action of the return spring 1007, which is convenient for the next strike.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, a grinding and pulverizing process for preparing meal replacement foods includes the following steps:

[0059] Step 1: Add the food ingredients to be ground into the grinding jar 1 through the feeding hopper 3. The food ingredients entering the grinding jar 1 will fall on the top of the top grinding disc 703. Since the top of the top grinding disc 703 is set in a funnel shape, the food ingredients will roll into the space between the top grinding disc 703 and the rotating grinding disc 705.

[0060] Step Two: Start motor 701 to drive hollow rotating shaft 702 to rotate rotating grinding disc 705. The food raw materials are ground by the top grinding disc 703, rotating grinding disc 705, and bottom grinding disc 704. The rotation of rotating grinding disc 705 coarsely grinds the food raw materials entering between the top grinding disc 703 and rotating grinding disc 705. The coarsely ground food raw materials then enter between rotating grinding disc 705 and bottom grinding disc 704. At this point, the rotation of rotating grinding disc 705 finely grinds the coarsely ground food raw materials entering between rotating grinding disc 705 and bottom grinding disc 704. The ground powdered food raw materials fall onto the top of guide plate 4. During the process between the top grinding disc 703 and the rotating grinding disc 705, the third helical gear 812 will rotate synchronously under the rotation of the second rotating rod 809, and then drive the rotating sleeve 901 to rotate through the third helical gear ring 902, causing the cutting rod 903 to revolve. At the same time, the rotation of the hollow rotating shaft 702 will drive the spiral plate 904 to rotate, so that the spiral plate 904 conveys the food raw materials. During the conveying process, the revolving cutting rod 903 will cut the food raw materials through the slot 905, initially reducing the particle size of the food raw materials, thereby facilitating the grinding of the food raw materials by the top grinding disc 703 and the rotating grinding disc 705, and improving the grinding efficiency.

[0061] Step 3: When the motor 701 starts, the air pump 13 starts synchronously, so that the air pump 13 draws the outside air into the installation cage 5 through the air inlet pipe 12, and injects it into the top grinding plate 703, the bottom grinding plate 704 and the rotating grinding plate 705 through the upper air outlet 14, the lower air outlet 15 and the plug pipe 16 respectively. The air entering the rotating grinding plate 705 will be dried by the dehumidification plate.

[0062] At the start of grinding, the air pump 13 is activated, drawing outside air into the intake pipe 12. The air is then divided into three streams through the upper outlet 14, lower outlet 15, and connector 16. The first stream enters the top grinding disc 703 to cool it, and the airflow absorbing the heat from the top grinding disc 703 is discharged through the second exhaust pipe 1012. The second stream enters the bottom grinding disc 704 to cool it, and the airflow absorbing the heat from the bottom grinding disc 704 is discharged through the first exhaust pipe 1011 and connector 16. The third airflow, after being dried by the desiccant in the dehumidifying plate, will enter the space formed by the rotating ring 804, the top grinding disc 703, and the bottom grinding disc 704. The dried airflow entering the space formed by the top grinding disc 703 and the bottom grinding disc 704 will enter the rotating grinding disc 705 through the connecting pipe 17, thereby achieving the purpose of cooling the rotating grinding disc 705, avoiding excessively high temperatures during the grinding process that would accelerate the wear of the grinding disc, extending the service life of the grinding disc, and reducing the probability of oxidation of powdered food raw materials, which would cause the nutritional components of the powdered food raw materials to be ineffective, thus ensuring the nutritional value of the produced meal replacement food.

[0063] Step 4: During the grinding of food raw materials, the first spiral brush 803 is brushed at the top of the bottom grinding disc 704, and the second spiral brush 810 is brushed at the top of the rotating grinding disc 705.

[0064] When the grinding disc 705 rotates, it drives the first rotating rod 802 to revolve, which in turn drives the rotating ring 804 to revolve. The revolve of the first rotating rod 802 drives the first helical gear 805 to move along the outer surface of the first helical gear ring 806, causing the first helical gear 805 to rotate during its movement. This, in turn, causes the first rotating rod 802 to rotate during its revolve, which in turn drives the first spiral brush 803 to rotate during its revolve. The spiral brush 803 then rolls and brushes the powdered food ingredients that are stuck between the rotating grinding disc 705 and the bottom grinding disc 704, preventing the powdered food ingredients from accumulating and sticking together, ensuring grinding efficiency, preventing the sticking of powdered food ingredients from contaminating the grinding of subsequent ingredients, and ensuring the quality of the prepared meal replacement food. During the revolve of the rotating ring 804, it drives the second helical gear ring 807 to revolve. During the revolution, the second helical gear 808 meshes with the second helical gear ring 807, causing the second helical gear 808 to drive the second rotating rod 809 to rotate, which in turn drives the second spiral brush 810 to rotate. This allows the second spiral brush 810 to brush the powdered raw materials stuck between the rotating grinding disc 705 and the top grinding disc 703, preventing the accumulation and adhesion of powdered food materials, ensuring grinding efficiency, preventing the adhesion of powdered food materials from contaminating the grinding of subsequent raw materials, and ensuring the quality of the prepared meal replacement food. Furthermore, since the first spiral brush 803 and the second spiral brush 810 are set in a spiral shape, and the spiral structure has a certain conveying function, it can further convey the powdered food materials, further reducing the probability of accumulation and adhesion of powdered food materials, thereby improving grinding efficiency.

[0065] Step 5: During this process, the hollow rotating shaft 702 drives the brush rod 1009 to rotate along the upper surface of the filter screen 1008, so that the powdered food raw materials with the required particle size pass through the filter screen 1008 and fall onto the top of the guide plate 4. The ground powdered food raw materials will fall onto the top of the filter screen 1008, so that the brush rod 1009 rotates along the top of the filter screen 1008 under the rotation of the hollow rotating shaft 702, avoiding the accumulation of powdered food raw materials on the top of the filter screen 1008, which would lead to low filtration efficiency of the filter screen 1008 for powdered food raw materials. This ensures the filtration efficiency of the filter screen 1008 for powdered food raw materials, and the filtered powdered food raw materials will fall onto the top of the guide plate 4.

[0066] The airflow entering the rotating grinding disc 705 absorbs the temperature of the rotating grinding disc 705, and then enters the brush rod 1009 through the hollow rotating shaft 702. It is then blown towards the top of the filter screen 1008 through the air blowing hole 1010, which avoids the accumulation of powdered food materials on the top of the filter screen 1008, thus preventing the filter screen 1008 from becoming inefficient in filtering powdered food materials. This ensures the filtration efficiency of the filter screen 1008 for powdered food materials. In addition, the blown air will also pass between the bottom grinding disc 704 and the rotating grinding disc 705, as well as between the rotating grinding disc 705 and the top grinding disc 703, further reducing the probability of powdered food materials sticking to the grinding discs, thereby improving the grinding efficiency of food materials.

[0067] Step 6: During the rotation of the hollow rotating shaft 702, the first wedge block 1002 pushes the second wedge block 1005 back and forth, causing the striking head 1006 to repeatedly strike the guide plate 4 under the action of the return spring 1007, so that the powdered food raw material obtained from grinding moves towards the discharge gate 2.

[0068] When the hollow rotating shaft 702 rotates, it will drive the fixed rod 1001 to rotate, causing the first wedge block 1002 to intermittently push the second wedge block 1005 upward, which in turn pushes the striking head 1006 to strike the guide plate 4 through the connecting rod 1004, causing the guide plate 4 to vibrate, which facilitates the movement of the powdered food raw materials on the top of the guide plate 4 towards the location of the discharge gate 2, making it easier to discharge and collect the powdered food raw materials. When the first wedge block 1002 is disengaged from the location of the second wedge block 1005, the striking head 1006 will be reset under the action of the return spring 1007, which will facilitate the next strike.

[0069] Step 7: After grinding, open the discharge door 2 to collect the powdered food raw materials obtained from grinding, and open the cleaning door 6 to clean the large particles of raw materials accumulated on the top of the filter screen 1008.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
