Description

Technical Field

[0001] The invention relates to the technical field of food processing, and more specifically to a nutrient batter production device for food processing. Background Art

[0002] Nutritional batter is a semi-fluid food raw material based on a variety of powdered raw materials. It is rich in various nutrients after reasonable formula design and processing. It is usually mixed with cereal flours such as wheat flour, corn flour, rice flour, and various nutritional enhancers such as milk powder, soybean powder, vitamins, minerals, etc. It can be used to make various baked foods, fried foods or as a thickener for soups, etc. It can provide rich nutrition and a specific taste. The production process of nutritional batter generally includes: raw material preparation, mixing, screening, slurry preparation, maturation, cooling and packaging. Among them, the mixed raw material powder needs to be screened through a filter screen to remove the existing lumps and coarse particles to ensure the uniformity and fineness of the particle size of the raw material powder.

[0003] At present, the raw powder screening of nutritious batter is generally carried out by using a rotary vibrating screen, but the existing rotary vibrating screen still has certain defects in the screening operation: 1. The current rotary vibrating screen mainly relies on the vibration generated by the vibration motor to realize material screening. In actual work, due to the lack of structural design to effectively limit the movement range of the material, the material cannot be arranged closely, and the material is in a relatively loose distribution state on the screen, which makes the distance between the materials larger, and the vibration energy is easily lost to the surrounding space during the transmission process. When it is transmitted from one particle to another, the loss and dispersion are serious, and the vibration conduction efficiency is low, which makes the screening efficiency of the raw powder need to be improved.

[0004] 2. At present, some rotary vibrating screens are also used for ultrasonic assisted screening. However, when ultrasonic waves propagate in the medium, ultrasonic thermal effects will be generated. When used on materials containing heat-sensitive nutritional enhancers (such as vitamin C, vitamin B 1 When the raw powder (such as flour, flour, etc.) is added to the batter, part of the sound energy is converted into heat energy, causing the local temperature of the raw powder to rise. These heat-sensitive nutritional enhancers are extremely sensitive to temperature. The increase in temperature will destroy their chemical structure, resulting in the loss of nutrients in the raw powder of the nutritious batter. Summary of the invention

[0005] The present invention provides a nutritious batter production device for food processing, which is used to solve the above technical problems.

[0006] The present invention provides a nutritious batter production device for food processing, comprising a frame and a body fixedly installed on the inner side of the frame, two screens distributed up and down are fixedly installed on the inner wall of the body, a lifting reciprocating mechanism is arranged on the top of the body, the lifting reciprocating mechanism comprises a reciprocating guide rod which rotates vertically and passes through the body and the two screens, and a reciprocating assembly used to drive the reciprocating guide rod to perform lifting and reciprocating motion, a pressure-stirring linkage screening mechanism is arranged on the outer side of the reciprocating guide rod for periodically applying force to the material through linear reciprocating motion, so that the material is dispersed under the action of pressure and shear force and contacts with the screen to generate high-frequency vibration screening, and the pressure-stirring linkage screening mechanism comprises a pressure-stirring screening assembly and a traction assembly used to traction the pressure-stirring screening assembly.

[0007] The pressure-stirring and screening assembly is provided with two groups distributed up and down, and the two groups of pressure-stirring and screening assemblies are respectively arranged above the working areas of the upper and lower layers of screens. The pressure-stirring and screening assembly includes a pressing plate and a mounting sleeve fixedly installed on the outside of the reciprocating guide rod and distributed up and down, a rotating sleeve is rotatably installed on the bottom of the mounting sleeve, and a number of stirring paddles distributed in a circle are fixedly installed on the outside of the rotating sleeve.

[0008] The traction assembly is arranged on the outer side of the rotating sleeve and is used to convert the linear lifting motion of the pressing plate into the rotating motion of the stirring paddle to disperse the material.

[0009] Furthermore, a periodic feeding mechanism is provided on the machine body, which includes an upper feeding assembly located at the top of the machine body and a lower feeding assembly located below the lower screen. A feeding pipe is installed on the front side of the machine body. While the upper feeding assembly feeds material to the top of the upper screen through the feeding pipe, the lower feeding assembly simultaneously feeds material to the top of the lower screen.

[0010] Furthermore, the upper feeding assembly includes two return springs 2 fixedly installed on the top of the machine body and symmetrically on the left and right, a return plate is commonly installed on the top of the two return springs 2, a lifting rod is fixedly installed on the bottom of the reset plate and slides through the top inner wall of the machine body, and the bottom end of the lifting rod is in conflict with the upper pressing plate, and two return rods are fixedly installed on the front side of the reset plate and symmetrically on the left and right, a sealing plate is commonly installed on the bottom ends of the two reset rods, and the sealing plate slides through the top inner wall of the feed pipe and seals with the bottom inner wall of the feed pipe.

[0011] Furthermore, the lower feed assembly includes a feed hopper fixedly mounted on the inner wall of the machine body and located below the upper screen, the bottom of the feed hopper is fixedly connected to the lower pressing plate via a flexible connecting tube, and the bottom end of the flexible connecting tube is fixedly passed through the lower pressing plate.

[0012] Furthermore, a T-shaped mounting frame is fixedly installed on the top of the feed hopper, the vertical section of the T-shaped mounting frame is coaxial with the flexible connecting pipe, and the bottom end of the vertical section of the T-shaped mounting frame passes through the flexible connecting pipe and is fixedly installed with a sealing cone, and the bottom diameter of the sealing cone matches the flexible connecting pipe to achieve a sealing fit.

[0013] Furthermore, the movement period of the pressure-stirring linkage screening mechanism is synchronized with the feeding frequency of the periodic feeding mechanism to form continuous screening.

[0014] Furthermore, the traction assembly includes a mounting cover fixedly mounted on the outside of the mounting sleeve and a gear fixedly mounted on the outside of the rotating sleeve, the mounting cover is in rotational contact with the rotating sleeve, a return spring 1 is fixedly mounted on the left inner wall of the mounting cover, the other end of the return spring 1 is fixedly mounted with a rack meshing with the gear and slidably connected to the bottom inner wall of the mounting cover, a fixed pulley 1 is rotatably mounted between the front and rear inner walls of the mounting cover, a fixed pulley 2 and a fixed plate distributed on the left and right are provided on the machine body, a traction rope is commonly wound around the outer sides of the fixed pulley 1 and the fixed pulley 2, and the two ends of the traction rope are respectively fixedly connected to the rack and the fixed plate.

[0015] Furthermore, the pressure-stirring linked screening mechanism also includes a support plate fixedly mounted on the right inner wall of the machine body and located between the two screens, the upper fixed pulley 2 and the fixed plate are both fixedly mounted on the top of the machine body, and the lower fixed pulley 2 and the fixed plate are both fixedly mounted on the top of the support plate.

[0016] Furthermore, two discharge pipes distributed up and down are fixedly installed on the outer side of the machine body, and the two discharge pipes are respectively located flush with the corresponding screens.

[0017] Furthermore, two vibration motors are fixedly mounted on the machine body in a front-to-back symmetric manner, and the vibration output shafts of the vibration motors are arranged along the vertical axis direction of the machine body.

[0018] The beneficial effects of the present invention are: 1. In the present application, during the pressing process of the pressing plate, the movement of the pressing plate itself is superimposed on the vibration transmitted by the vibration motor, generating a constantly changing force. At the same time, the pressing plate presses down to compress the material, the particle spacing becomes smaller, the extrusion pressure increases, and part of the material is squeezed out of the original position and dispersed to the surroundings, causing the pressure distribution to change continuously, making the frequency of change of the resultant force on the material higher, and finally prompting the material to generate high-frequency vibration screening between the pressing plate and the screen, thereby greatly improving the screening effect.

[0019] 2. In the present application, the downward pressure of the pressing plate also limits the movement range of the materials, so that the materials are tightly arranged in a small space. When subjected to the vibration force from the movement of the pressing plate and the vibration motor, the materials distributed in a small range are closer to each other, and the vibration energy can be transferred from one particle to another more quickly and directly, reducing the loss and dispersion of energy during the transmission process. Therefore, the vibration conduction between materials is more efficient, thereby further improving the screening effect.

[0020] 3. In the present application, the rotation of the agitator can break up the aggregated material clumps, making the material looser, increasing the contact area and opportunity between the material and the screen, and the stirring of the agitator and the cooperation of the pressing plate realize efficient screening of the material, avoiding the low screening efficiency of ordinary rotary vibrating screens and the problem of easy loss of material nutrients caused by ultrasonic rotary vibrating screens.

[0021] 4. In the present application, the downward movement of the pressure plate, the stirring of the agitator and the periodic feeding mechanism are all driven by a reciprocating assembly, which greatly reduces the cost of use. Moreover, being driven by the same reciprocating assembly can ensure that the downward movement of the pressure plate, the stirring of the agitator and the feeding of the feeding assembly are precisely synchronized. When the pressure plate presses down the material, the upper feeding assembly just completes the feeding and prepares the material for subsequent screening; at the same time, the agitator starts stirring to assist in dispersing the material, so that the entire screening process is closely connected and proceeds in an orderly manner. This high degree of coordination avoids problems such as insufficient material processing, excessive or insufficient feeding due to inconsistent working rhythms of the components, and greatly improves the smoothness and stability of the equipment operation.

DETAILED DESCRIPTION

[0029] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0030] See also Figure 1 and Figure 2 In this embodiment, a nutritious batter production device for food processing is proposed, including a frame 1 and a body 2 fixedly installed on the inner side of the frame 1, two screens 9 distributed up and down are fixedly installed on the inner wall of the body 2, and a lifting reciprocating mechanism 3 is arranged on the top of the body 2. The lifting reciprocating mechanism 3 includes a reciprocating guide rod 302 that rotates vertically and passes through the body 2 and the two screens 9 and a reciprocating assembly 301 for driving the reciprocating guide rod 302 to perform lifting and reciprocating motion. The outer side of the reciprocating guide rod 302 is provided with a pressure-stirring linkage screening mechanism 4 for periodically applying force to the material through linear reciprocating motion, so that the material is dispersed under the action of pressure and shear force and contacts with the screen 9 to generate high-frequency vibration screening. The pressure-stirring linkage screening mechanism 4 includes a pressure-stirring screening assembly 401 and a traction assembly 402 for traction The pressure-stirring screening assembly 401 causes the pressure-stirring screening assembly 401 to rotate and stir the material.

[0031] It should be noted that the reciprocating assembly 301 may adopt a conventional reciprocating screw drive structure, etc. This is common knowledge to those skilled in the art, and therefore will not be described in detail in this application.

[0032] See also Figure 1 and Figure 2 The machine body 2 is provided with a periodic feeding mechanism 5, the movement period of the pressure-stirring linkage screening mechanism 4 is synchronized with the feeding frequency of the periodic feeding mechanism 5 to form continuous screening, and two vibration motors 8 are fixedly installed on the machine body 2 in a front-to-back symmetrical manner, and the vibration output shaft of the vibration motor 8 is arranged along the vertical axis direction of the machine body 2, and a feeding pipe 6 is installed on the front side of the machine body 2, and two discharge pipes 7 distributed up and down are fixedly installed on the outside of the machine body 2, and the two discharge pipes 7 are respectively located flush with the corresponding screens 9, and a discharge port (not shown in the figure) is opened at the bottom of the machine body 2.

[0033] See also Figure 2 , Figure 3 and Figure 5 The pressure-stirring and screening assembly 401 is provided with two groups distributed up and down, and the two groups of pressure-stirring and screening assemblies 401 are respectively arranged above the working areas of the upper and lower layers of the screens 9. The pressure-stirring and screening assembly 401 includes a pressing plate 4014 and a mounting sleeve 4011 fixedly installed on the outside of the reciprocating guide rod 302 and distributed up and down. A rotating sleeve 4012 is rotatably installed at the bottom of the mounting sleeve 4011, and a plurality of stirring paddles 4013 distributed in a circle are fixedly installed on the outside of the rotating sleeve 4012.

[0034] See also Figure 1-Figure 6During screening, the mixed material enters the machine body 2 through the feed pipe 6. While feeding, the reciprocating assembly 301 drives the reciprocating guide rod 302 to perform lifting and reciprocating motion, driving the upper and lower pressing plates 4014 to move downward synchronously and slowly at a uniform speed, thereby gradually pressing the material downward until the stirring paddle 4013 moves close to the screen 9 and the pressing plate 4014 stops and remains for a few seconds for continuous screening. The material is subjected to pressure between the pressing plate 4014 and the screen 9. At the same time, the vibration motor 8 works, and its vibration output shaft arranged along the vertical axis direction of the machine body 2 generates a vibration force, which is transmitted to the screen 9 and the pressing plate 4014 through the machine body 2. During the pressing process of the pressing plate 4014, its own movement is superimposed on the vibration transmitted by the vibration motor 8 to generate a constantly changing force. At the same time, the pressing plate 4014 presses downward to compress the material, reduce the particle distance, increase the extrusion pressure, and part of the material is squeezed out of the original position and dispersed around, so that The pressure distribution changes continuously, so that the frequency of change of the resultant force on the material is higher, and finally the material generates high-frequency vibration between the pressing plate 4014 and the screen 9, and the downward pressure of the pressing plate also limits the movement range of the material, so that the material is tightly arranged in a small space. When subjected to the vibration force from the movement of the pressing plate 4014 and the vibration motor 8, because the materials are closer to each other in a small range, the vibration energy can be transferred from one particle to another more quickly and directly, reducing the loss and dispersion of energy in the transmission process. Therefore, the vibration conduction between materials is more efficient, thereby further improving the screening effect. At this time, medium-sized particle materials with a particle size smaller than the aperture of the screen 9 pass through the screen 9 to achieve screening, and large-sized particle materials with a particle size larger than the aperture of the screen 9 are blocked by the screen 9. At the same time, the stirring paddle 4013 rotates under the action of the traction component 402 to further disperse the material, break up the sticky material, and improve the screening effect.

[0035] When the stirring paddle 4013 moves close to the screen 9, the pressing plate 4014 stops and remains for a few seconds to continue screening. Then, the reciprocating assembly 301 continues to work to drive the reciprocating guide rod 302 to start rising, thereby driving the pressing plate 4014 to rise. During the rising process of the pressing plate 4014, first, the stirring paddle 4013 rotates again under the action of the traction assembly 402 to assist the material discharge. Then, the pressing plate 4014 continues to rise until it returns to the initial position (such as Figure 2 to complete a complete up and down movement cycle.

[0036] During the downward movement of the pressing plate 4014, the periodic feeding mechanism 5 will gradually stop feeding, and during the upward movement of the pressing plate 4014, it will gradually start feeding again.

[0037] See also Figure 2 , Figure 3 , Figure 4 and Figure 5The traction assembly 402 is arranged on the outside of the rotating sleeve 4012 and is used to convert the linear lifting motion of the pressing plate 4014 into the rotational motion of the stirring paddle 4013 to disperse the agglomerated or bonded materials.

[0038] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The traction assembly 402 includes a mounting cover 4021 fixedly mounted on the outside of the mounting sleeve 4011 and a gear 4022 fixedly mounted on the outside of the rotating sleeve 4012. The mounting cover 4021 is in rotational contact with the rotating sleeve 4012. A return spring 4023 is fixedly mounted on the left inner wall of the mounting cover 4021. The other end of the return spring 4023 is fixedly mounted with a rack 4024 meshing with the gear 4022 and slidably connected to the bottom inner wall of the mounting cover 4021. A fixed pulley 4025 is rotatably mounted between the front and rear inner walls of the mounting cover 4021. A fixed pulley 4028 and a fixed plate 4026 distributed on the left and right are provided on the body 2. A traction rope 4027 is commonly wound around the outer sides of the fixed pulley 4025 and the fixed pulley 4028. The two ends of the traction rope 4027 are respectively fixedly connected to the rack 4024 and the fixed plate 4026.

[0039] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The pressure-stirring linkage screening mechanism 4 also includes a support plate 403 fixedly mounted on the right inner wall of the body 2 and located between the two screens 9, the upper fixed pulley 4028 and the fixed plate 4026 are both fixedly mounted on the top of the body 2, and the lower fixed pulley 4028 and the fixed plate 4026 are both fixedly mounted on the top of the support plate 403.

[0040] See also Figure 1-Figure 6 , during the screening process, as the pressing plate 4014 descends, the mounting sleeve 4011 will be synchronously driven to move downward, and the mounting cover 4021 will move downward accordingly. In this process, first, the traction rope 4027, which is initially in a relaxed state, is gradually tightened and straightened. When the traction rope 4027 is straightened and the mounting cover 4011 continues to move downward, the traction rope 4027 will, under the guidance of the fixed pulley 1 4025 and the fixed pulley 2 4028, pull the rack 4024 to slide on the inner wall of the bottom of the mounting cover 4021 and drive the gear 4022 to drive the rotating sleeve 4012 to rotate, thereby causing the stirring paddle 4013 distributed circumferentially outside the rotating sleeve 4012 to rotate, thereby stirring and dispersing the material between the pressing plate 4014 and the screen 9. When the stirring paddle 4013 moves close to the screen 9, the pressing plate 4014 and the mounting sleeve 4011 stop moving, the stirring paddle 4013 stops rotating, and the material is vibrated and screened at high frequency between the pressing plate 4014 and the screen 9.

[0041] When the pressing plate 4014 rises, the mounting cover 4021 moves upward, the traction rope 4027 is relaxed, and under the action of the reset spring 4023, the rack 4024 slides in the opposite direction, driving the gear 4022 and the rotating sleeve 4012 to rotate in the opposite direction, and the stirring paddle 4013 also rotates in the opposite direction. In this way, during the lifting and lowering process of the pressing plate 4014, the stirring paddle 4013 rotates again to assist the discharge of large and medium-sized particles blocked by the screen 9, while preventing the accumulation or residue of materials inside the machine body 2.

[0042] See also Figure 2 , Figure 4 and Figure 6 The periodic feeding mechanism 5 includes an upper feeding assembly 501 located at the top of the machine body 2 and a lower feeding assembly 502 located below the screen 9. While the upper feeding assembly 501 feeds materials to the top of the upper screen 9 through the feeding pipe 6, the lower feeding assembly 502 feeds materials to the top of the lower screen 9 synchronously.

[0043] See also Figure 2 , Figure 4 and Figure 6 The upper feeding assembly 501 includes two return springs 5011 fixedly installed on the top of the machine body 2 and symmetrically on the left and right. A return plate 5012 is commonly installed on the top of the two return springs 5011. A lifting rod 5015 that slides through the top inner wall of the machine body 2 is fixedly installed on the bottom of the return plate 5012, and the bottom end of the lifting rod 5015 is in conflict with the upper pressing plate 4014. Two return rods 5013 that are symmetrical on the left and right are fixedly installed on the front side of the return plate 5012. A sealing plate 5014 is commonly installed on the bottom ends of the two return rods 5013. The sealing plate 5014 slides through the top inner wall of the feed pipe 6 and seals with the bottom inner wall of the feed pipe 6.

[0044] See also Figure 1-Figure 6In the initial state, the second reset spring 5011 is in a stretched state, and the bottom end of the sealing plate 5014 does not contact the inner wall of the feed pipe 6. When the pressure-stirring linkage screening mechanism 4 starts to work, as the reciprocating guide rod 302 drives the pressing plate 4014 to descend, the second reset spring 5011 will generate a downward pulling force on the reset plate 5012. After the reset plate 5012 is subjected to the pulling force, it gradually moves downward. During the descending process of the reset plate 5012, the two reset rods 5013 also drive the sealing plate 5014 to move downward. 5014 slides in the feed pipe 6 and gradually closes the channel of the feed pipe 6. At this time, the pressure plate 4014 continues to move downward, and the lifting rod 5015 will be separated from the upper pressure plate 4014 (because the sealing plate 5014 is already in close contact with the bottom wall of the feed pipe 6 at this time, and the return spring 5011 cannot continue to contract), thereby stopping the feeding. Then, the pressure plate 4014 continues to move downward, and when the stirring paddle 4013 moves close to the screen 9, the pressure plate 4014 stops and remains for a few seconds for continuous screening.

[0045] When the pressing plate 4014 rises and resets, as the pressing plate 4014 moves, the upper pressing plate 4014 will gradually approach the lifting rod 5015. In this process, large particles and medium particles are gradually discharged through the discharge pipe 7. After the large particles and medium particles are discharged, the upper pressing plate 4014 contacts the lifting rod 5015, and then as the pressing plate 4014 continues to move upward, it will lift the lifting rod 5015, thereby driving the reset plate 5012 to move upward and stretch the reset spring 2 5011, thereby driving the sealing plate 5014 to rise. The sealing plate 5014 opens the channel of the feed pipe 6 and feeds material to the top of the upper screen 9 again. In this way, through the lifting and lowering movement of the pressing plate 4014, with the help of the coordinated operation of the reset spring 2 5011, the reset plate 5012, the reset rod 5013 and the sealing plate 5014 and other components, the periodic feeding of the upper feeding component 501 is realized.

[0046] See also Figure 2 , Figure 4 and Figure 6 The lower feed assembly 502 includes a feed hopper 5021 fixedly mounted on the inner wall of the machine body 2 and located below the upper screen 9. The bottom of the feed hopper 5021 is fixedly connected to the lower pressing plate 4014 through a flexible connecting tube 5022, and the bottom end of the flexible connecting tube 5022 is fixedly passed through the lower pressing plate 4014.

[0047] See also Figure 2 , Figure 4 and Figure 6A T-shaped mounting bracket 5023 is fixedly installed on the top of the feed hopper 5021, the vertical section of the T-shaped mounting bracket 5023 is coaxial with the flexible connecting tube 5022, and the bottom end of the vertical section of the T-shaped mounting bracket 5023 passes through the flexible connecting tube 5022 and is fixedly installed with a sealing cone 5024, the bottom diameter of the sealing cone 5024 is consistent with the flexible connecting tube 5022 to achieve a sealing fit.

[0048] See also Figure 1-Figure 6 When the lower pressing plate 4014 descends with the reciprocating guide rod 302, the flexible connecting tube 5022 can gradually stretch to adapt to the movement of the pressing plate 4014. During the descending process of the pressing plate 4014, when the upper pressing plate 4014 moves to the sealing plate 5014 to close and stop the feeding of the feed pipe 6, the lower pressing plate 4014 drives the bottom opening of the flexible connecting tube 5022 to move to the outside of the sealing cone 5024 to stop feeding synchronously. Then, the medium-sized particle material on the top of the lower screen 9 (the medium-sized particle material screened by the upper screen 9 will fall to the top of the lower screen 9 through the lower feeding assembly 502) is subjected to high-frequency vibration screening again between the lower pressing plate 4014 and the lower screen 9.

[0049] When the lower pressing plate 4014 rises with the reciprocating guide rod 302, when the upper pressing plate 4014 moves and drives the sealing plate 5014 to open and the feed pipe 6 feeds again, the lower pressing plate 4014 drives the bottom opening of the flexible connecting tube 5022 to move above the sealing cone 5024. At this time, the medium-sized particle material that falls on the top of the feed hopper 5021 after screening by the upper screen 9 will fall to the top of the lower screen 9 through the flexible connecting tube 5022 and wait for secondary screening. The fine particle material after the secondary screening is discharged through the discharge port at the bottom of the body 2.

[0050] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
