At this time, the first bevel gear in the rolling brush mechanism rotates under the action of the first bevel gear ring, thereby causing the first rotating rod to drive the first spiral brush to rotate. At the same time, the rotation of the rotating ring will drive the second bevel gear to rotate through the second bevel gear ring, and then drive the second spiral brush to rotate through the second rotating rod, so that the first spiral brush rolls and brushes the powdered food raw materials bonded between the rotating grinding disc and the gap between the bottom grinding disc, and the second spiral brush rolls and brushes the powdered raw materials bonded between the rotating grinding disc and the gap between the top grinding disc, thereby avoiding the accumulation and adhesion of the powdered food raw materials, ensuring the grinding efficiency, preventing the adhesion of the powdered food raw materials from contaminating the grinding of subsequent raw materials, and ensuring the quality of the prepared meal replacement food.

[0031] 3. The present invention uses an air pump, an air inlet pipe, an upper air outlet, a lower air outlet, a plug-in tube and a connecting pipe to draw outside air into the top grinding disc, the bottom grinding disc and the rotating grinding disc of the grinding mechanism respectively, so as to cool down the top grinding disc, the bottom grinding disc and the rotating grinding disc, thereby avoiding accelerated wear of the grinding disc due to excessively high temperature during the grinding process, extending the service life of the grinding disc, and reducing the probability of oxidation of powdered food raw materials, which causes the nutritional components of the powdered food raw materials to become ineffective, thereby ensuring the nutritional value of the produced meal replacement food.

[0032] 4. The present invention intermittently blows air to the upper surface of the filter screen through the brush rod, which on the one hand avoids the accumulation of powdered food raw materials on the top of the filter screen, resulting in low filtering efficiency of the filter screen for powdered food raw materials, thereby ensuring the filtering efficiency of the filter screen for powdered food raw materials; on the other hand, the blown gas will pass between the bottom grinding disc and the rotating grinding disc, and between the rotating grinding disc and the top grinding disc, further reducing the probability of powdered food raw materials sticking between the grinding discs, thereby improving the grinding efficiency of food raw materials.

The powdered food raw materials after filtration will fall on the top of the guide plate 4, and the airflow entering the rotating grinding disc 705 absorbs the temperature of the rotating grinding disc 705, enters the brush rod 1009 through the hollow shaft 702, and is blown to the top of the filter screen 1008 through the air blowing hole 1010, thereby avoiding the accumulation of powdered food raw materials on the top of the filter screen 1008, resulting in the low efficiency of the filter screen 1008 for filtering the powdered food raw materials, thereby ensuring the filtering efficiency of the filter screen 1008 for the powdered food raw materials. In addition, the blown gas 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, thereby further reducing the probability of the powdered food raw materials adhering to the grinding discs, thereby improving the grinding efficiency of the food raw materials.

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

[0057] When the hollow rotating shaft 702 rotates, it will drive the fixed rod 1001 to rotate, so that the first wedge block 1002 intermittently pushes the second wedge block 1005 upward, and then pushes the knocking head 1006 to knock on the material guide plate 4 through the connecting rod 1004, so that the material guide plate 4 vibrates, which facilitates the movement of the powdered food raw materials on the top of the material guide plate 4 to the position of the discharge door 2, and facilitates the discharge and collection of the powdered food raw materials. When the first wedge block 1002 is separated from the position of the second wedge block 1005, the knocking head 1006 will be reset under the action of the reset spring 1007, which is convenient for the next knocking.

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

[0059] Step 1: Add the food materials to be ground into the grinding tank 1 through the feeding hopper 3. The food materials entering the grinding tank 1 will fall on the top of the top grinding disc 703. At this time, since the top of the top grinding disc 703 is set in a funnel shape, the food materials will roll into between the top grinding disc 703 and the rotating grinding disc 705;

[0060] Step 2: Start the motor 701 so that the hollow rotating shaft 702 drives the rotating grinding disc 705 to rotate, and grind the food raw materials through the top grinding disc 703, the rotating grinding disc 705 and the bottom grinding disc 704. The food raw materials entering between the top grinding disc 703 and the rotating grinding disc 705 are roughly ground by the rotation of the rotating grinding disc 705, and the roughly ground food raw materials will enter between the rotating grinding disc 705 and the bottom grinding disc 704. At this time, the roughly ground food raw materials entering between the rotating grinding disc 705 and the bottom grinding disc 704 are finely ground by the rotation of the rotating grinding disc 705, and the ground powdered food raw materials will fall on the top of the guide plate 4. During the process of entering between the top grinding disc 703 and the rotating grinding disc 705, the third bevel gear 812 will rotate synchronously with the rotation of the second rotating rod 809, and then drive the rotating sleeve 901 to rotate through the third bevel gear ring 902, so that the cutting rod 903 revolves, and 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 notch 905, preliminarily reducing the particle size of the food raw materials, thereby facilitating the top grinding disc 703 and the rotating grinding disc 705 to grind the food raw materials, thereby improving the grinding efficiency;

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

[0062] When grinding starts, the air pump 13 is started so that the air pump 13 draws outside air into the air inlet pipe 12, and then the air in the air inlet pipe 12 is divided into three air flows through the upper air outlet 14, the lower air outlet 15 and the plug-in pipe 16, so that the first air flow enters the top grinding disc 703 to cool down the top grinding disc 703, and the air flow that absorbs the temperature in the top grinding disc 703 will be discharged through the second exhaust pipe 1012, and the second air flow enters the bottom grinding disc 704 to cool down the bottom grinding disc 704, and the air flow that absorbs the temperature in the bottom grinding disc 704 will be discharged through the first exhaust pipe 1011, and the plug-in pipe 16 The discharged third airflow will enter the space formed by the rotating ring 804, the top grinding disc 703 and the bottom grinding disc 704 after being dried by the desiccant in the dehumidifying plate. The dry 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 the accelerated wear of the grinding disc due to excessive temperature during the grinding process, extending the service life of the grinding disc, and reducing the probability of oxidation of the powdered food raw materials, which causes the nutritional components of the powdered food raw materials to become ineffective, thereby ensuring the nutritional value of the produced meal replacement food;

[0063] Step 4: During the grinding of the food material, the first spiral brush 803 rolls on the top of the bottom grinding disc 704, and the second spiral brush 810 rolls on the top of the rotating grinding disc 705;

[0064] When the rotating grinding disc 705 rotates, it will drive the first rotating rod 802 to revolve, and then drive the rotating ring 804 to revolve. The revolution of the first rotating rod 802 will drive the first bevel gear 805 to move along the outer surface of the first bevel gear ring 806, so that the first bevel gear 805 rotates during the movement, and then the first rotating rod 802 rotates during the revolution, and then drives the first spiral brush 803 to rotate during the revolution, so that the first spiral brush 803 rolls and brushes the powdered food raw materials bonded between the rotating grinding disc 705 and the bottom grinding disc 704, avoiding the accumulation and adhesion of the powdered food raw materials, ensuring the grinding efficiency, preventing the adhesion of the powdered food raw materials from contaminating the grinding of subsequent raw materials, and ensuring the quality of the prepared meal replacement food. During the revolution of the rotating ring 804, the second bevel gear ring 807 will be driven Revolution, at this time, since the second bevel gear 808 is meshed with the second bevel gear ring 807, the second bevel gear 808 will drive the second rotating rod 809 to rotate, and then drive the second spiral brush 810 to rotate, so that the second spiral brush 810 rolls and brushes the powdered raw materials bonded between the rotating grinding disc 705 and the top grinding disc 703, avoiding the accumulation and adhesion of powdered food raw materials, ensuring the grinding efficiency, preventing the adhesion of powdered food raw materials from contaminating the subsequent grinding of raw materials, and ensuring the quality of the prepared meal replacement food. In addition, since the first spiral brush 803 and the second spiral brush 810 are arranged in a spiral form, and the spiral form structure has a certain conveying function, the powdered food raw materials can be further conveyed, further reducing the probability of accumulation and adhesion of powdered food raw materials, thereby improving the 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 on the top of the guide plate 4, and the ground powdered food raw materials will fall on 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, thereby avoiding the accumulation of powdered food raw materials on the top of the filter screen 1008, resulting in low efficiency of filtering the powdered food raw materials by the filter screen 1008, ensuring the filtering efficiency of the filter screen 1008 for the powdered food raw materials, and the filtered powdered food raw materials will fall on the top of the guide plate 4;

[0066] After the airflow entering the rotating grinding disc 705 absorbs the temperature of the rotating grinding disc 705, it enters the brush rod 1009 through the hollow rotating shaft 702, and is blown to the top of the filter screen 1008 through the blowing hole 1010, thereby avoiding the accumulation of powdered food materials on the top of the filter screen 1008, resulting in low efficiency of filtering the powdered food materials by the filter screen 1008, thereby ensuring the filtering efficiency of the powdered food materials by the filter screen 1008. 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, thereby further reducing the probability of the powdered food materials adhering to the grinding discs, thereby improving the grinding efficiency of the food materials.

[0067] Step 6: During the rotation of the hollow shaft 702, the first wedge block 1002 reciprocates to push the second wedge block 1005 so that the striking head 1006 reciprocates to strike the guide plate 4 under the action of the return spring 1007, so that the ground powdered food material moves toward the discharge gate 2;

[0068] When the hollow rotating shaft 702 rotates, it will drive the fixed rod 1001 to rotate, so that the first wedge block 1002 intermittently pushes the second wedge block 1005 upward, and then pushes the knocking head 1006 to knock the material guide plate 4 through the connecting rod 1004, so that the material guide plate 4 shakes, which facilitates the powdered food raw materials on the top of the material guide plate 4 to move to the position where the discharge door 2 is located, and facilitates the discharge and collection of the powdered food raw materials. When the first wedge block 1002 is separated from the position where the second wedge block 1005 is located, the knocking head 1006 will be reset under the action of the reset spring 1007, which is convenient for the next knocking;

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

[0070] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
