Description

Technical Field

[0001] This invention relates to the field of food additives technology, and in particular to an intelligent mixing system for industrial processing of compound food additives. Background Technology

[0002] One existing method for producing compound food additives involves first mixing liquid and powdered additives to obtain a semi-finished food additive, then drying the semi-finished product to remove moisture and obtain the desired food additive. When liquid and powdered additives are mixed, a large amount of heat is released due to the change in pH. Traditional mixers have the following drawbacks when mixing solid and liquid raw materials:

[0003] Defect 1: Although traditional mixers can cool down the mixing drum by adding cooling pipes, they still cannot dissipate heat evenly inside the drum, which can easily cause the middle part of the material to overheat during mixing, thus affecting the quality of the food additives produced.

[0004] Defect 2: If the mixing drum wall is cooled, the water vapor generated during the mixing process will directly liquefy on the drum wall and flow back into the mixture. When the liquid additive and powder additive are highly mixed, their fluidity decreases. If condensate flows down at this time, it will be difficult to mix the condensate evenly again, which will easily cause uneven moisture content in the semi-finished food additive, thus affecting the quality of the produced food additive.

[0005] Defect 3: During the mixing process of liquid and powdered additives, due to the prolonged maintenance of high temperatures, the liquid additives in the mixing drum will evaporate and mix into the air within the drum. If this is not addressed promptly, a large amount of mixed gases will escape from the mixing drum after the semi-finished food additive is discharged, causing environmental pollution. Although existing technologies can extract and purify the air inside the mixing drum, the air pressure inside the drum will decrease after extraction. Since lower air pressure leads to faster evaporation of the liquid additives, this results in a significant loss of liquid additives during mixing, thus affecting the quality of the food additives.

[0006] To address the above shortcomings, there is an urgent need to develop an intelligent mixing system for the industrial processing of compound food additives. Summary of the Invention

[0007] To overcome the shortcomings of existing mixers that cannot effectively dissipate heat when mixing liquid and powder additives, resulting in localized overheating of materials and affecting the quality of food additives, this invention provides an intelligent mixing system for industrial processing of compound food additives.

[0009] To further explain, the re-stirring assembly includes an L-shaped actuating plate, an inner swirl tube, and a first actuating rod; the lower end of the stirring blade is fixedly connected to the L-shaped actuating plate, and the L-shaped actuating plate is in contact with the first return pipe; the L-shaped part of the L-shaped actuating plate is grid-shaped; the lower end of the stirring blade is rotatably connected to the inner swirl tube, and one end of the inner swirl tube is connected to the cavity of the stirring blade, and the other end is connected to the second return pipe; the inner swirl tube is a return pipe with threads designed inside; several sets of first actuating rods are fixedly connected to the surface of the inner swirl tube.

[0010] To further explain, the condensation system includes a condenser tube and an annular water collection cylinder; the top cover is fixedly connected to the condenser tube, and one end of the condenser tube is connected to the first temporary storage box, and the other end is connected to the second temporary storage box; the condenser tube is fixedly connected to the annular water collection cylinder, and the lower surface of the top cover can be heated.

[0011] Further explanation: The circulating purification system includes miniature air pumps, guide plates, connecting pipes, annular water collection pipes, communicating vessels, and water injection pipes. Several miniature air pumps are installed on the lower surface of the annular water collection cylinder, and the air outlets of the miniature air pumps are all connected to the annular water collection cylinder. A guide plate is fixedly connected to the annular water collection cylinder, and the guide plate partially wraps around the annular water collection cylinder from above. Several connecting pipes are fixedly connected to the annular water collection cylinder and the guide plate, and an upward-facing one-way valve is installed inside the connecting pipe. The one-way valve can be switched to a normally open or normally closed state. An annular water collection pipe is fixedly connected inside the top cover, and the annular water collection pipe is connected to all connecting pipes. Several through holes are opened in the top cover. A communicating vessel is installed on the upper surface of the top cover, and the communicating vessel is connected to the annular water collection pipe through several through holes. A water injection pipe is connected to the annular water collection pipe.

[0012] To further explain, the auxiliary feeding system includes connecting rods, a mounting shell, a driver, a lead screw, a movable screen, and a second actuating rod; the mixing cylinder is fixedly connected to multiple connecting rods; the multiple connecting rods are jointly fixedly connected to the mounting shell; the driver is installed inside the mounting shell; the driver is rotatably connected to the lead screw; the lead screw is fixedly connected to the movable screen; and the movable screen is fixedly connected to several second actuating rods.

[0013] To further explain, the lower surface of the top cover is W-shaped.

[0016] To further explain, the guide plate surface is covered with a smooth hydrophobic layer.

[0017] To further explain, the second lever is an inclined arc-shaped plate.

[0018] The beneficial effects of this invention are as follows: By setting up a stirring fan blade with a cavity, the coolant is directly introduced into the stirring fan blade to cool the material and maintain the temperature inside the mixing cylinder at 50 to 60 degrees Celsius. This facilitates mixing while preventing local overheating. Furthermore, the re-stirring component breaks up and stirs the clumps of material again at the bottom of the mixing cylinder. During the stirring process, the temperature of the stirring part is maintained through the first return pipe, further improving the stirring effect and significantly improving the quality of the obtained food additive.

[0019] This invention incorporates a condensation system that liquefies evaporated water vapor on condenser tubes and collects the liquefied condensate, preventing it from flowing back into the mixture and ensuring a uniform distribution of moisture content in the semi-finished food additive.

[0020] This invention incorporates a circulating purification system. During the feeding of powder additives, the air containing volatile liquid additives is cleaned twice and then discharged from the mixing cylinder, creating a negative pressure in the mixing cylinder. This facilitates the feeding of powder additives while preventing water vapor and air containing liquid additives from escaping through the powder inlet and causing the powder additives to be stirred up. Furthermore, it prevents the powder additives from agglomerating due to premature contact with water vapor, thus ensuring smooth feeding of the powder additives.

[0021] Furthermore, after the addition of powdered additives is stopped, the air in the mixing drum can be circulated through the circulation purification system to continue removing liquid additives from the air. During this process, the air pressure in the mixing drum will not change, thereby preventing the evaporation rate of liquid additives from accelerating by preventing the air pressure from decreasing. This avoids the large loss of liquid additives, which would lead to a decrease in the content of liquid additive components in the finished food additive product. Attached Figure Description

Detailed Implementation

[0037] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0038] Example 1

[0039] A smart mixing system for industrial processing of compound food additives, such as Figure 1-8 As shown, it includes a mounting frame 1, a mixing cylinder 2, a top cover 3, a first temporary storage box 4, and a second temporary storage box 5; the mounting frame 1 is fixedly connected to the mixing cylinder 2; the mixing cylinder 2 is bolted to the top cover 3; the top cover 3 has a liquid inlet 3a on the right side for feeding liquid additives and a powder inlet 3b on the left side for feeding powder additives; the first temporary storage box 4 is fixedly connected to the upper surface of the top cover 3 for temporarily storing coolant before use; the second temporary storage box 5 is fixedly connected to the upper surface of the first temporary storage box 4 for temporarily storing coolant after use; the first temporary storage box 4 and the second temporary storage box 5 are connected by an external coolant circulation device, which draws coolant from the second temporary storage box 5, cools it down, and then sends it back to the first temporary storage box 4 for use;

[0040] It also includes a motor 6, a connecting cylinder 7, stirring blades 8, a first return pipe 9, a second return pipe 10, a re-stirring assembly, a condensation system, a circulation purification system, and an auxiliary feeding system; the motor 6 is bolted to the top cover 3; the output shaft of the motor 6 is fixedly connected to the connecting cylinder 7, which is rotatably connected to both the first temporary storage box 4 and the second temporary storage box 5, and the connecting cylinder 7 communicates with the first temporary storage box 4; four stirring blades 8 are fixedly connected to the connecting cylinder 7; each stirring blade 8 has a cavity, and each cavity communicates with the connecting cylinder 7, through which coolant is injected into the cavity to directly cool the stirring blades 8. The temperature inside the mixing cylinder 2 is rapidly reduced; each stirring blade 8 is fixedly connected to a set of first return pipes 9, and each set of first return pipes 9 is connected to the cavity inside the corresponding stirring blade 8; the first return pipes 9 are made of metal; a second return pipe 10 is fixedly connected inside the connecting cylinder 7, and the lower end of the second return pipe 10 is connected to each of the first return pipes 9, and the upper end passes through the connecting cylinder 7 and is connected to the second temporary storage tank 5. The coolant in the cavity of the stirring blade 8 flows back to the second temporary storage tank 5 through the first return pipes 9 and the second return pipes 10 to complete the circulating cooling work; a re-stirring component is connected to the lower end of each stirring blade 8.

[0041] like Figure 7-8 As shown, the re-stirring assembly includes an L-shaped actuating plate 101, an inner swirl tube 102, and a first actuating rod 103. The lower end of the stirring blade 8 is fixedly connected to the L-shaped actuating plate 101, and the L-shaped actuating plate 101 is in contact with the first return pipe 9. The L-shaped actuating plate 101 is made of aluminum alloy, and its L-shaped part is grid-like. The lower end of the stirring blade 8 is rotatably connected to the inner swirl tube 102, and one end of the inner swirl tube 102 is connected to the cavity of the stirring blade 8, and the other end is connected to the second return pipe 10. The inner swirl tube 102 is a return pipe with threads designed inside. Several sets of first actuating rods 103 are fixedly connected to the surface of the inner swirl tube 102 and distributed between the grids of the L-shaped actuating plate 101. When the coolant flows through the inner swirl tube 102, it will drive the inner swirl tube 102 to rotate through the threads designed inside the tube, thereby driving the first actuating rod 103 to rotate and breaking up the clumps of material.

[0042] It is worth mentioning that in this embodiment, the liquid additive can be lactic acid and the powder additive can be calcium lactate. This embodiment uses lactic acid and calcium lactate as examples for explanation.

[0043] The working principle of the above embodiment 1 is as follows:

[0044] When this system is working, the liquid additives and powder additives to be mixed are first prepared manually according to the proportions. The liquid additives are then fed into the mixing cylinder 2 through the liquid inlet 3a. Then, the motor 6 drives the connecting cylinder 7 and the stirring blades 8 to rotate clockwise from top to bottom, stirring the liquid additives in the mixing cylinder 2. At the same time, the external feed hopper is connected through the through hole 3c, and the powder additives are slowly added to the mixing cylinder 2 through the external feed hopper, so that the powder additives are mixed into the liquid additives until they are evenly mixed to obtain the lactic acid powder semi-finished product.

[0045] It is important to note that during the mixing process, the coolant in the first temporary storage tank 4 and the second temporary storage tank 5 is circulated by an external coolant circulation device. The coolant in the second temporary storage tank 5 is cooled by the coolant circulation device and then flows into the first temporary storage tank 4. After flowing out of the first temporary storage tank 4, the coolant flows through the connecting cylinder 7 and is then introduced into the cavity of the stirring blade 8 to cool the stirring blade 8. This cooling of the stirring blade 8 during the mixing of liquid and powder additives prevents overheating in the middle of the material and improves the quality of the resulting food additive. Subsequently, the cooled coolant in the cavity of the stirring blade 8 is returned to the second temporary storage tank 5 through the first return pipe 9 and the second return pipe 10, completing the cooling process. This maintains the temperature inside the mixing cylinder 2 at 50 to 60 degrees Celsius, facilitating mixing while preventing localized overheating. It is important to note that during the mixing process, powdered additives need to be added to the liquid additives while simultaneously stirring. Because the powdered additives are difficult to disperse immediately upon addition, clumping occurs after they mix with the liquid additives, requiring prolonged stirring to eliminate the clumps. During mixing, the motor 6 drives the stirring blades 8 to rotate clockwise from top to bottom via the connecting cylinder 7. As the stirring blades 8 rotate, they continuously push the upper layer of material downwards to the bottom of the mixing cylinder 2, forcing the material back up along the side wall of the mixing cylinder 2, thus completing material circulation and achieving the mixing process. However, during the process of the material being pushed to the bottom of the mixing cylinder 2 by the stirring blades 8, the clumps of material, due to their weak flowability, easily accumulate at the lower end of the stirring blades 8. Furthermore, because the clumps have a certain volume, they become stuck between the L-shaped agitator plates 101. During the process of the coolant in the cavity of the stirring fan blade 8 flowing back to the first return pipe 9 through the inner swirl tube 102, the inner swirl tube 102 will rotate counterclockwise from left to right, thereby causing the first actuating rod 103 to rotate counterclockwise, which in turn agitates the clumps of material between the grids of the L-shaped actuating plate 101, breaks them up and sends them out of the L-shaped actuating plate 101, achieving the effect of re-stirring, removing material clumps, and significantly improving the quality of the produced food additive.

[0046] It should be noted that although the present invention continuously cools the material by introducing coolant into the cavity of the stirring blade 8, powder additives are still continuously added to the mixing cylinder 2 from the powder feed inlet 3b. This causes the upper liquid additives to come into contact with and mix with the powder additives, releasing a large amount of heat. After being cooled by the stirring blade 8, the upper material will be maintained in the optimal stirring temperature range of 50 to 60 degrees Celsius. However, the material transported to the lower layer by the stirring action will be cooled to a lower temperature. Due to the lower temperature, the stirring effect of the lower material is not good. Therefore, the present invention sets up a second return pipe 10 to conduct the heat of the coolant at a higher temperature after flowing out of the cavity of the stirring blade 8 to the L-shaped deflector plate 101, thereby maintaining the L-shaped deflector plate 101 at a higher temperature. This heats the agglomerated material at the grid of the L-shaped deflector plate 101, further improving the stirring effect of the first deflector rod 103.

[0047] Example 2

[0048] Based on Example 1, such as Figure 9-10 As shown, the condensation system includes a condenser pipe 201 and an annular water collection cylinder 202; the top cover 3 is fixedly connected to the condenser pipe 201, and one end of the condenser pipe 201 is connected to the first temporary storage box 4, and the other end passes through the first temporary storage box 4 and is connected to the second temporary storage box 5, for circulating the coolant so that water vapor condenses on the condenser pipe 201; the condenser pipe 201 is fixedly connected to the annular water collection cylinder 202 by several fixed rods for collecting condensate; the lower surface of the top cover 3 can be heated so that the condensate is generated only on the condenser pipe 201 and drips onto the annular water collection cylinder 202, preventing the condensate from flowing back into the mixing cylinder 2 and affecting the quality of the food additives.

[0049] The circulating purification system includes a miniature air pump 301, a guide plate 302, a connecting pipe 303, an annular water collection pipe 304, a communicating vessel 305, and a water injection pipe 306. At least eight miniature air pumps 301 are installed on the lower surface of the annular water collection cylinder 202, and the air outlets of all miniature air pumps 301 are connected to the annular water collection cylinder 202. A guide plate 302 is fixedly connected to the upper surface of the outer ring of the annular water collection cylinder 202, and the guide plate 302 slopes downwards from above towards the center, partially wrapping the annular water collection cylinder 202. At least eight connecting pipes are jointly fixed to the annular water collection cylinder 202 and the guide plate 302. 303, and a one-way valve is installed inside the connecting pipe 303. The one-way valve allows one-way passage from bottom to top and can be switched to normally open or normally closed state; an annular water collection pipe 304 is fixedly connected inside the top cover 3, and the annular water collection pipe 304 is connected to all connecting pipes 303; the top cover 3 has several inclined through holes 3c; a communicating vessel 305 is installed on the upper surface of the top cover 3, and the communicating vessel 305 is connected to the annular water collection pipe 304 through several through holes 3c; the annular water collection pipe 304 is connected to a water injection pipe 306, which is used to inject distilled water into the annular water collection pipe 304 to clean the gas in the mixing cylinder 2.

[0050] The working principle of the above embodiment 2 is as follows: It should be noted that before the mixing operation, the one-way valve in the control connecting pipe 303 is switched to the normally open state. At this time, the one-way valve is ineffective and only serves to connect the components. Then, distilled water is manually injected into the open water injection pipe 306, allowing the distilled water to flow into the annular water collection pipe 304 along the water injection pipe 306, and then into the annular water collection cylinder 202 through the connecting pipe 303. After the distilled water level in the annular water collection cylinder 202 rises to contact the lower end of the guide plate 302, the one-way valve in the control connecting pipe 303 is switched to the normally closed state. At this time, the one-way valve operates normally, and gas or liquid can only flow from bottom to top. The injection of distilled water into the annular water collection cylinder 202 is stopped, thereby forming a triangular gap between the distilled water in the annular water collection cylinder 202 and the guide plate 302. The cavity is connected to the connecting pipe 303, and then distilled water is injected until the distilled water fills the annular water collecting pipe 304. Then, the injection of distilled water is stopped and the water inlet of the water injection pipe 306 is closed. During the mixing process, the coolant in the first temporary storage tank 4 also flows to the second temporary storage tank 5 through the condenser pipe 201, so that the condenser pipe 201 is maintained at a low temperature. The water vapor evaporated during the mixing process gathers below the top cover 3 and condenses into water droplets on the surface of the condenser pipe 201. The water droplets are then collected in the annular water collecting cylinder 202, which prevents the water vapor from condensing at an uncertain location and flowing back into the mixing cylinder 2, causing uneven distribution of the material's moisture content. This prevents the uneven baking degree caused by the moisture content distribution when baking the food additive semi-finished product, thus ensuring the quality of the finished food additive product.

[0051] It is important to note that during the powder additive feeding process, first, the communicating vessel 305 is opened, and the one-way valve in the connecting pipe 303 is kept normally closed. Then, the micro air pump 301 is controlled to continuously extract air from the mixing cylinder 2 and introduce it into the distilled water in the annular water collecting cylinder 202. This dissolves the volatile liquid additives in the water, thus purifying the air. The purified air rises to the cavity between the guide plate 302 and the distilled water, and is then introduced into the annular water collecting pipe 304 through the connecting pipe 303. The distilled water in the annular water collecting pipe 304 further purifies the air. After the second cleaning, the liquid additive is discharged from the mixing cylinder 2 through the through hole 3c and the communicating vessel 305 to prevent the air mixed with the liquid additive from entering the atmosphere and causing pollution. During this process, the air inside the mixing cylinder 2 is extracted to create a negative pressure inside the mixing cylinder 2. This facilitates the feeding of the powder additive while preventing the air containing water vapor and liquid additive inside the mixing cylinder 2 from escaping through the powder inlet 3b and causing the powder additive to be thrown up. It also further prevents the powder additive from agglomerating after premature contact with water vapor, thus ensuring the smooth feeding of the powder additive.

[0052] It is important to note that during the mixing process of lactic acid and calcium lactate, due to the prolonged maintenance of a high temperature, the lactic acid inside mixing cylinder 2 will volatilize and mix into the air within mixing cylinder 2. If this is not addressed promptly, a large amount of vaporized lactic acid will be mixed into the air and drift out of mixing cylinder 2 after the lactic acid powder semi-finished product is discharged, causing environmental pollution. Although existing technology can extract and purify the air inside mixing cylinder 2, the air pressure inside the cylinder will decrease after extraction. Since the lower the air pressure, the faster the lactic acid evaporates, resulting in a significant loss of lactic acid during the mixing process, thus reducing the lactic acid content in the finished lactic acid powder.

[0053] It should be noted that, due to the volatility of liquid additives, maintaining a high temperature in the mixing cylinder 2 for an extended period will cause the liquid additives to evaporate. Therefore, the air in the mixing cylinder 2 needs to be purified before being discharged. Although existing technology can extract the air from the mixing cylinder 2 for purification, the air pressure inside the mixing cylinder 2 will decrease after the air is extracted. Since the lower the air pressure, the faster the liquid additives evaporate, a large amount of liquid additives will be lost during the mixing process, resulting in a decrease in the content of liquid additive components in the finished food additive product. Therefore, after the powder additive is added, this invention controls the powder inlet 3b and the communicating vessel 305 to close simultaneously, and controls the micro air pump 3 to close. 01. Continue to extract air. After the air is sent to the area below the guide plate 302, it cannot rise further due to the closure of the communicating vessel 305. As a result, the air accumulates below the guide plate 302. The air continuously compresses the liquid surface below the guide plate 302, causing the liquid surface to drop and separate from the guide plate 302. This allows the gas to bypass the guide plate 302 and escape from the side of the annular water collecting cylinder 202 that is not covered by the guide plate 302, returning to the mixing cylinder 2. This completes the internal circulation of air in the mixing cylinder 2. In this way, while maintaining a constant air pressure in the mixing cylinder 2, the liquid additives mixed in with the air in the mixing cylinder 2 are continuously removed, preventing the air containing liquid additives that accumulates during discharge from floating out of the mixing cylinder 2 and causing pollution.

[0054] Example 3

[0055] Based on Example 2, such as Figure 14 As shown, the auxiliary feeding system includes connecting rods 401, mounting shell 402, driver 403, lead screw 404, movable screen 405, and second actuating rods 406. Four connecting rods 401 are fixedly connected to the discharge port at the lower end of the mixing cylinder 2. The multiple four connecting rods 401 are fixedly connected to the mounting shell 402. The driver 403 is installed inside the mounting shell 402. The driver 403 is rotatably connected to the lead screw 404. The lead screw 404 is fixedly connected to the movable screen 405. Several second actuating rods 406 are fixedly connected along the arc surface on the upper surface of the movable screen 405 to cooperate with the stirring blades 8 to move the material and assist in the discharge of food additive semi-finished products.

[0056] The lower surface of the top cover 3 is W-shaped, which is used to guide the condensate to the condenser pipe 201, so that the annular water collecting cylinder 202 can collect the condensate.

[0057] A hydraulic sensor is designed inside the second return pipe 10 to check the pressure inside the second return pipe 10 in real time in order to detect whether the coolant is leaking.

[0058] The first actuating lever 103 is L-shaped. When stirring agglomerated materials, it can first break up the agglomerated materials, and then break them up by rotating the actuating lever, thereby improving the stirring effect of the agglomerated materials.

[0059] A flow-limiting valve is installed at the outlet of the inner vortex tube 102, and the inlet is enlarged to increase the flow rate of the coolant in the inner vortex tube 102, thereby increasing the rotation speed of the inner vortex tube 102 and the first actuating rod 103, and thus improving the stirring effect of the first actuating rod 103.

[0060] The lower surface of the annular water collecting cylinder 202 is designed with heating elements to prevent condensation from forming on the lower surface of the annular water collecting cylinder 202.

[0061] The guide plate 302 has a smooth hydrophobic layer on its surface, which can prevent air bubbles from remaining and improve the cleaning effect of distilled water on the gas.

[0062] The second actuating lever 406 is an inclined arc-shaped plate, which can squeeze the material outward of the movable screen 405 when mixing the material, so that the material can be discharged from the bottom of the movable screen 405 along the arc-shaped bottom surface of the mixing cylinder 2.

[0063] The working principle of the above embodiment 4 is as follows: After the liquid additive and powder additive are mixed evenly, the cooling cycle is stopped. Then, the motor 6 drives the connecting cylinder 7 and the stirring fan blade 8 to continue rotating and feeding downwards. The driver 403 drives the lead screw 404 to rotate upwards, thereby lifting the movable screen 405 and the second actuating rod 406 and driving the movable screen 405 and the second actuating rod 406 to rotate. The second actuating rod 406 then stirs the lactic acid powder semi-finished product again, assisting its discharge action. When the lead screw 404 repeatedly rotates up and down along the direction of the driver 403, that is, in the vertical direction, it drives the movable screen 405 to move back and forth in the up and down direction, thereby squeezing the food additive semi-finished product downwards, further assisting its discharge action. The food additive semi-finished product is squeezed out of the mixing cylinder 2 and collected, completing the mixing work.

[0064] It should be noted that after the mixing work is completed, the top cover 3 and the parts installed on it can be disassembled together to clean the mixing cylinder 2. Before disassembly, the one-way valve in the control connecting pipe 303 should be switched to the normally open state, and then the cleaning fluid should be injected into the water injection pipe 306 for cleaning. The cleaning fluid should be introduced into the annular water collection cylinder 202 through the annular water collection pipe 304 and the connecting pipe 303 in sequence, and the annular water collection cylinder 202 and each pipe fitting should be flushed to flush out the distilled water containing the liquid additive from the mixing cylinder 2, thus completing the pre-cleaning work.

[0065] Although the invention has been described with reference to exemplary embodiments, it should be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
