Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to an integrated anti-caking, drying, and grinding device for potato flour preparation. Background Technology

[0002] Potato starch, also known as potato flour, is a powdered food made from potatoes through a series of processes including washing, peeling, slicing, blanching, drying, crushing, and sieving. Because it retains most of the components of potatoes, such as starch, vitamins, and minerals, potato starch has a more complete potato flavor and nutrition. It has a wide range of applications in food processing. For example, it is often added to flour to improve the texture of bread or pastries, and it also has a certain thickening ability, so it can be used in soups, sauces, fillings, and so on.

[0003] In the existing patent CN112337551A, an integrated flour drying and grinding device is disclosed, including a horizontally placed turning roller. A drive roller seat and a driven roller seat are respectively installed on both sides of the turning roller to rotatably support both ends of the turning roller. The interior of the turning roller is provided with multiple spiral-shaped turning protrusions for cooperating with the turning roller to transport powder. A powder separation and guiding mechanism for gathering and turning powder is installed laterally inside the turning roller, and a powder grinding mechanism is installed laterally inside the turning roller, located directly below the discharge of the powder separation and guiding mechanism. An air curtain generated by an air curtain generating mechanism separates the ground powder, allowing the fully ground powder to be blown into a fine powder accelerating frame and spiral forward. This allows the fully ground powder to move to the discharge port of the turning roller faster than the insufficiently ground powder, enhancing the efficiency of drying and grinding the powder.

[0004] The above structure can achieve the drying and grinding effect of powder. However, in the potato starch production process, it is necessary to first use the increased temperature to dry the powder to remove moisture and prevent clumping, then transport the powder, and finally grind the powder. However, this traditional method results in an excessively long production line, which leads to a complex structure, reduced production efficiency, difficulty in achieving integrated equipment, large space occupation, difficulty in optimizing enterprise scale, increased energy consumption, increased enterprise costs, and is detrimental to enterprise development and market competitiveness.

[0005] Therefore, how to provide an integrated anti-caking, drying, and grinding device for potato flour preparation is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Two adjacent cooling pipes are spirally connected through the connecting pipe. The cooling pipes are stacked, and the inner diameter of the upper layer of cooling pipes is adapted to the outer diameter of the lower layer of cooling pipes.

[0012] Preferably, the cooling assembly is a cooling tank on the grinding box, a booster pump 2 is installed on the grinding box, the output end of the booster pump 2 is provided with a cooling liquid outlet pipe that communicates with the cooling pipe at the tail end, and a cooling liquid return pipe that communicates with the cooling pipe at the head end is provided on the cooling tank.

[0016] The beneficial effects of this invention are as follows:

[0017] This invention uses a lifting assembly to lower the grinding and heating assemblies to a suitable position, maintaining a distance between the grinding assembly and the grinding chamber. This allows the grinding assembly to rotate, forcing the potato flour to disperse around the grinding chamber. A heating assembly introduces heat-conducting oil into the heating assembly, transferring the high temperature of the oil to the potato flour, thus achieving a drying effect and reducing its moisture content. After drying, the lifting assembly further lowers the grinding assembly, creating a grinding state between it and the grinding chamber, forcing the grinding assembly to grind the potato flour. A cooling assembly introduces coolant into a cooling unit, allowing the cooling unit to remove the heat generated during grinding. After grinding, the process is completed... The lifting assembly is activated in reverse to a suitable position, causing it to pull the grinding assembly back to the same position. Through the combined operation of the cooling and heating assemblies, a temperature gradient is created within the potato flour, resulting in different expansion coefficients between the flour particles. This forces the potato flour to loosen automatically, effectively preventing clumping. This invention integrates the drying, grinding, and anti-caking functions into a single unit through temperature control, significantly reducing the production line size, increasing production efficiency, simplifying the structure, minimizing space requirements, facilitating optimization of enterprise scale, reducing energy consumption, lowering production and maintenance costs, and ultimately benefiting enterprise development and market competitiveness.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0031] Example 1:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, an integrated anti-caking and drying grinding device for potato flour preparation according to the present invention includes a grinding box 1, a feeding pipe 2 on the grinding box 1, a connecting pipe 3 controlled by a control system on the grinding box 1, a sieving box 4 connected to the connecting pipe 3, a receiving box 5 for receiving standard powder and a collecting box 6 for collecting large particles of powder placed on the sieving box 4, a lifting component 7 inside the grinding box 1, a grinding component 8 at the output end of the lifting component 7, a heating component 9 inside the grinding component 8, a heating component 10 connected to the heating component 9 on the grinding box 1, and a cooling component 11 around the outer ring of the grinding box 1. The grinding box 1 is equipped with a cooling component 12 and an adjusting component 13 connected to the cooling component 11. The screening box 4 is equipped with a screening component 14 and a releasing component 15 for releasing large particles of powder. During drying, the heating component 10 is activated, causing the heating component 9 to increase the temperature and achieve the drying effect on the potato flour. During grinding, the cooling component 12 is activated, causing the cooling component 11 to decrease the temperature and achieve the cooling effect during grinding. To prevent caking, the heating component 10 and the cooling component 12 work synchronously to form a temperature gradient and reduce the caking of the potato flour.

[0033] Working Principle: By shutting down the control system, the connecting pipe 3 is in a closed state. Potato flour is added to the grinding chamber 1 through the feeding pipe 2. During drying, the lifting component 7 is activated, causing the grinding component 8 and heating component 9 to descend to a suitable position, maintaining a distance between the grinding component 8 and the grinding chamber 1. The grinding component 8 is then activated, causing it to rotate and forcing the potato flour to disperse around the grinding chamber 1. Simultaneously, the heating component 10 is activated, allowing heat transfer oil to be introduced into the heating component 9. Through the heat conduction of the grinding component 8, the high-temperature heat transfer oil is transferred to the potato flour, thereby achieving the drying effect and reducing the moisture content of the potato flour. After drying is completed, the heating function of the heating component 10 is stopped, and the lifting component 7 is activated again. The lifting assembly 7 drives the grinding assembly 8 to continue descending, creating a grinding state between the grinding assembly 8 and the grinding chamber 1, i.e., the potato flour comes into contact with the grinding assembly 8. The grinding assembly 8 is then activated, and under the resistance of the grinding chamber 1, it is forced to grind the potato flour. Since heat is generated during grinding, to prevent the potato flour from overheating, the cooling assembly 12 is activated, directing coolant into the cooling assembly 11 to remove the heat generated during grinding within the grinding chamber 1. After grinding, because the powder still contains a small amount of moisture, it is prone to clumping. Anti-caking treatment is required, so the lifting assembly 7 is reversed and moved to a suitable position, causing the grinding assembly 8 to continue descending. The grinding assembly 8 is stopped after retracting to a suitable position, while the heating assembly 10 is activated, allowing heat transfer oil to enter the heating assembly 9. At this time, the cooling assembly 11 and the heating assembly 9 work together. The potato flour is positioned between the cooling assembly 11 and the heating assembly 9, creating a temperature gradient from high to low within the potato flour. This difference in expansion coefficients forces the potato flour to loosen automatically, effectively preventing clumping. Simultaneously, the heating assembly 9 provides high temperature to further evaporate any remaining moisture, significantly reducing the final moisture content of the potato flour. After completion, the control system is activated, allowing the potato flour to continuously fall onto the screening assembly 14 inside the screening box 4. The screening assembly 14 then screens the potato flour, allowing standard-sized particles to fall out. Larger potato flour particles are collected in the receiving box 5, while larger particles remain on the screening component 14. The release component 15 is controlled to release the larger particles of potato flour from the screening component 14 into the collecting box 6. The larger particles of potato flour in the collecting box 6 are then poured into the feeding pipe 2 for continuous grinding. In summary, the potato flour preparation anti-caking drying and grinding integrated device of this application integrates the drying, grinding and anti-caking functions into one unit through temperature control, thereby achieving device integration. This greatly reduces the production line size, improves production efficiency, simplifies the structure, occupies less space, facilitates the optimization of enterprise scale, reduces enterprise energy consumption, reduces production and maintenance costs, and benefits enterprise development and market competitiveness.

The screening component 14 includes a screening screen plate 1401 disposed in a screening box 4. The screening screen plate 1401 is inclined and a vibration motor 1402 is installed on the screening screen plate 1401. The end of the screening screen plate 1401 corresponds to the outlet of the grinding box 1, and the receiving box 5 corresponds to the screening screen plate 1401.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides an integrated anti-caking drying and grinding device for potato flour preparation. The release component 15 includes an electric push rod 1501 installed on the screening box 4. The output end of the electric push rod 1501 is provided with a connecting plate 1502. The connecting plate 1502 is provided with a baffle 1503 that penetrates the screening box 4. The baffle 1503 is located at the end of the screening screen plate 1401.

[0044] Working Principle: The control system is shut down, keeping the connecting pipe 3 closed. Potato flour is added to the grinding chamber 1 through the feeding pipe 2. During drying, the hydraulic lifting rod 701 is activated, causing its output end to lower the connecting block 702. This lowers the grinding motor 801, rotating pipe 802, grinding roller 803, drive gear 804, and driven gear 805. The grinding roller 803 lowers the heat-conducting box 901, output pipe 902, and input pipe 903 to a suitable position, creating a distance between the grinding roller 803 and the inner wall of the grinding chamber 1. The grinding motor 801 is then activated, its output shaft rotating, causing the drive gear 804 to rotate. This rotation, in turn, causes the driven gear 805 to rotate, which in turn rotates the rotating pipe 802, which in turn rotates the grinding roller 803. The grinding process continues. The grinding roller 803 drives the heat-conducting box 901, the output pipe 902, and the input pipe 903 to rotate. The grinding roller 803 forces the potato flour to disperse around the inner wall of the grinding box 1. At the same time, the booster pump 1002 is started, which introduces the heat-conducting oil in the heating box 1001 into the heating oil outlet pipe 1003. The heat-conducting oil is then introduced into the connecting block 702 through the heating oil outlet pipe 1003. Since the space inside the connecting block 702 is small, the heat-conducting oil enters the heat-conducting box 901 along the input pipe 903, exits through the connecting block 702 through the output pipe 902, and enters the heating box 1001 through the heating return pipe 1004, completing the heating cycle. The grinding roller 803 is set as a heat-conducting material. Through the heat conduction effect between the heat-conducting box 901 and the grinding roller 803, the temperature of the high-temperature heat-conducting oil is transferred to the potato flour, thereby achieving the drying effect of the potato flour and reducing the moisture content of the potato flour.

[0045] After drying, stop the booster pump 1002 and restart the hydraulic lifting rod 701. This causes the output end of the hydraulic lifting rod 701 to drive the connecting block 702 to continue descending. The connecting block 702 then drives the grinding motor 801, rotating pipe 802, grinding roller 803, drive gear 804, and driven gear 805 to descend. The grinding roller 803 drives the heat-conducting box 901, output pipe 902, and input pipe 903 to a suitable position. At this point, the grinding roller 803 is in a grinding state with the inner wall of the grinding box 1, meaning the potato starch is in contact with the grinding roller 803. Start the grinding motor 801. The output shaft of the grinding motor 801 rotates, driving the drive gear 804 to rotate. The drive gear 804 then drives the driven gear 805 to rotate. The rotation of gear 805 drives the rotation of rotating tube 802, which in turn drives the rotation of grinding roller 803. Under the resistance of grinding box 1, the grinding roller 803 is forced to grind the potato flour. Since heat is generated during the grinding process and residual heat is generated during drying, in order to avoid the potato flour temperature from becoming too high, booster pump 1202 is started during the grinding process. Booster pump 1202 introduces the coolant in cooling box 1201 into cooling outlet pipe 1203, and then into cooling pipe 1101. The coolant circulates in cooling pipe 1101 and returns to cooling box 1201 through cooling return pipe 1204, so that the coolant carries away the heat and residual heat generated in grinding box 1, achieving a cooling effect during grinding.

[0046] After grinding, the powder still contains a small amount of moisture, which can easily cause clumping. Therefore, anti-caking treatment is necessary. The hydraulic lifting rod 701 is reversed and moved to a suitable position, causing the connecting block 702 to drive the grinding motor 801, rotating pipe 802, grinding roller 803, drive gear 804, and driven gear 805 back up to the suitable position. The grinding motor 801 is then stopped, and the booster pump 1002 is started simultaneously. The booster pump 1002 guides the heat transfer oil from the heating box 1001 to the heating oil outlet pipe 1003. The heat transfer oil is then guided into the connecting block 702 through the heating oil outlet pipe 1003. Due to the small space within the connecting block 702, the heat transfer oil enters the heat transfer box 901 along the input pipe 903 and exits through the output pipe 902. The heating return oil pipe 1004 enters the heating box 1001, causing the heat transfer oil to circulate. High temperature is generated inside the heat transfer box 901, while low temperature is generated outside the grinding box 1 by the cooling pipe 1101. Under the heat conduction effect of the heat transfer box 901 and the grinding roller 803, high temperature is generated inside the grinding box 1. The coolant and heat transfer oil work synchronously. At this time, the potato flour is between the cooling pipe 1101 and the heat transfer box 901, that is, the two sides of the potato flour are in high temperature environment and low temperature environment respectively. This forces the potato flour to form a temperature gradient from high to low, resulting in different expansion coefficients between the powders. This forces the potato flour to automatically loosen, effectively preventing the potato flour from clumping. At the same time, the high temperature provided by the heat transfer oil can further evaporate the small amount of water, which greatly reduces the moisture content of the final potato flour.

[0047] In this process, a temperature gradient is generated inside the potato flour. However, when there is a small amount of potato flour, i.e., it is located at the bottom of the grinding box 1, the coolant in the upper layer has a long path, which can easily cause the potato flour in the lower layer to cool for a longer time. At this time, the electric push rod 1302 is activated in sequence. The output end of the electric push rod 1302 drives the corresponding connecting rod 1303 to move, so that the cooling pipe 1101 of the upper layer and the cooling pipe 1101 of the lower layer are superimposed, thereby greatly shortening the coolant path, greatly improving the cooling effect, facilitating the rapid loosening of potato flour, and improving processing efficiency.

[0048] After completion, the control system is turned on, causing potato flour to continuously fall from the grinding box 1 onto the screening screen 1401 in the screening box 4. The vibration motor 1402 is started, causing the screening screen 1401 to vibrate continuously, thus screening the potato flour. Under the action of gravity, standard-sized potato flour particles fall from the screening screen 1401 into the receiving box 5. Due to the inclined setting of the screening screen 1401, larger potato flour particles remain on the screening screen 1401. On one side of 401, corresponding to the outlet of screening box 4, start electric push rod 1501. The output end of electric push rod 1501 drives the connecting plate 1502 to move, causing the connecting plate 1502 to drive the baffle 1503 to move, so that the large particles of potato starch on screening screen plate 1401 fall into collection box 6. Pour the large particles of potato starch in collection box 6 into feeding pipe 2 to achieve circulating grinding. After receiving box 5 is completed, take out receiving box 5 to complete the collection of standard potato starch.

[0049] This solution cleverly controls the temperature of the device, integrating its drying, grinding, and anti-caking functions into a single unit. This integrated approach significantly reduces the size of the production line, improves production efficiency, simplifies the structure, minimizes space requirements, facilitates optimization of enterprise scale, reduces energy consumption, lowers production and maintenance costs, and ultimately benefits enterprise development and market competitiveness.
