[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0026] Figure 1 This is an almond grinding system provided by the embodiment of the present application. Figure 1 The almond grinding system provided in the embodiment of the present application includes a first grinding device 110, a second grinding device 120, a buffer unit 140 and a control unit 130. The buffer unit 140 is located between the first grinding device 110 and the second grinding device 120, and the buffer unit 140 is connected to the first grinding device 110 and the second grinding device 120 respectively.

[0027] The first grinding device 110 can be used for, but is not limited to, grinding almonds once to obtain almond paste of a first particle size.

[0028] For example, the first grinding device 110 can be any device capable of grinding almonds, and this application does not impose any restrictions in this regard. For example, the first grinding device 110 includes a first housing and a first grinding disc disposed in an inner cavity of the first housing, wherein the first grinding disc includes a first sub-grinding disc and a second sub-grinding disc disposed oppositely. The first sub-grinding disc and the second sub-grinding disc disposed oppositely can be used for, but are not limited to, grinding the almonds through the mutual shear force between the first sub-grinding disc and the second sub-grinding disc.

[0029] The first shell can be used for, but is not limited to, collecting almond paste of first particle size obtained after the first sub-grinding disc and the second sub-grinding disc grind the almonds once, so as to deliver the almond paste of first particle size to the cache unit 140, and isolate the almond paste of first particle size from the outside of the first shell to avoid contamination of the almond paste of first particle size.

[0030] In some embodiments, the first grinding disc is made of corundum to ensure the grinding efficiency of the almonds when the first grinding device 110 grinds the almonds once, while preventing the almond paste of the first particle size from being contaminated.

[0031] In order to further improve the grinding efficiency of almonds when the first grinding device 110 grinds almonds once, the first grinding disc may, for example, include a first abrasive, the material of the first abrasive may, for example, be corundum, and the first abrasive may, for example, be arranged in a free manner between the first sub-grinding disc and the second sub-grinding disc, or may be arranged in a solid manner on the opposite side of the first sub-grinding disc and the second sub-grinding disc.

[0032] In some embodiments, the first grinding device 110 grinds the almonds in a dry grinding manner, that is, no water or other liquid medium is added during the grinding process.

[0033] The second grinding device 120 can be used for, but is not limited to, receiving almond paste of a first particle size and performing secondary grinding on the almond paste of the first particle size to obtain almond paste of a second particle size.

[0034] In some embodiments, the inner wall of the first shell is a mirror inner wall.

[0035] Alternatively, the second grinding device 120 can be any device capable of grinding almond paste of the first particle size, and the present application does not impose any restrictions in this regard. For example, the second grinding device 120 includes a second shell and a second grinding disc arranged in the inner cavity of the second shell, and the second grinding disc includes a third sub-grinding disc and a fourth sub-grinding disc arranged opposite to each other. Among them, the third sub-grinding disc and the fourth sub-grinding disc arranged opposite to each other can be used for, but not limited to, grinding the almond paste of the first particle size by the mutual shear force between the first sub-grinding disc and the second sub-grinding disc. The second shell can be used for, but not limited to, collecting the almond paste of the second particle size obtained after the third sub-grinding disc and the fourth sub-grinding disc grind the almond paste of the first particle size for the second time, so as to transport the almond paste of the second particle size to the downstream of the almond grinding system, and isolate the almond paste of the second particle size from the outside of the second shell to avoid contamination of the almond paste of the second particle size.

[0036] In some embodiments, the second grinding disc is made of corundum to ensure the grinding efficiency of the second grinding device 120 when performing secondary grinding on the almond paste of the first particle size, while preventing the almond paste of the second particle size from being contaminated.

[0037] In order to further improve the grinding efficiency of the second grinding device 120 when performing secondary grinding on the almond paste of the first particle size, the second grinding disc may, for example, include a second abrasive, the material of the second abrasive may, for example, be corundum, and the second abrasive may, for example, be arranged in a free manner between the third sub-grinding disc and the fourth sub-grinding disc, or may be arranged in a fixed manner on the opposite side of the third sub-grinding disc and the fourth sub-grinding disc.

[0038] In some embodiments, the second grinding device 120 performs secondary grinding on the almond paste of the first particle size by dry grinding, that is, no water or other liquid medium is added during the secondary grinding process.

[0039] In some embodiments, the particle size of the first almond paste obtained by the first grinding device 110 grinding the almonds once is larger than the particle size of the second almond paste obtained by the second grinding device grinding the almonds twice.

[0040] The buffer unit 140 can be used, but is not limited to, to provide a buffer space between the first grinding device 110 and the second grinding device 120. This prevents the grinding system from pausing when the first grinding device 110 and the second grinding device 120 have different grinding speeds, thereby improving the production efficiency of the grinding system. For example, when the first grinding device 110 and the second grinding device 120 have different grinding speeds, the buffer unit 140 can temporarily store the almond paste of a first particle size obtained after a single grinding of almonds by the first grinding device 110, and then deliver the almond paste of the first particle size to the second grinding device 120.

[0041] In some embodiments, the cache unit 140 can be a pipeline between the first grinding device 110 and the second grinding device 120 for connecting the first grinding device 110 and the second grinding device 120, or the cache unit 140 can also be an independent device for storing almond paste of the first particle size arranged between the first grinding device 110 and the second grinding device 120. The present application does not impose any restrictions in this regard.

[0042] The control unit 130 can be used for, but is not limited to, controlling the first grinding device 110 to deliver almond paste of the first particle size to the buffer unit 140 , and controlling the buffer unit to deliver almond paste of the first particle size to the second grinding device 120 .

[0043] As mentioned above, the buffer unit 140 can be used to provide a buffer space between the first grinding device 110 and the second grinding device. Considering the limited capacity of the buffer unit 140, when the remaining capacity in the buffer unit 140 is small, the buffering effect of the buffer space provided by the buffer unit 140 may be affected.

[0044] In view of this, the embodiment of the present application can dynamically adjust the storage amount of the almond paste of the first particle size in the cache unit 140 through the control unit 130, so that the cache unit 140 can better play a buffering role.

[0045] For example, the control unit 130 is configured to control the first grinding device 110 to stop feeding the first-size almond paste to the cache unit 140 when the amount of almond paste of the first size stored in the cache unit 140 exceeds a first threshold; and to control the first grinding device 110 to feed the first-size almond paste to the cache unit when the amount of almond paste of the first size stored in the cache unit 140 falls below a second threshold. The first threshold is greater than the second threshold. The values of the first and second thresholds can be set based on the actual capacity of the cache unit 140, and this application does not impose any limitations in this respect.

[0046] In some embodiments, the buffer unit 140 is provided with a sensor for detecting the storage amount of the almond paste of the first particle size in the buffer unit 140. The sensor for detecting the almond paste of the first particle size in the buffer unit 140 includes, for example, a pressure sensor, an optical sensor, a capacitive sensor, an ultrasonic sensor, or any other device that can detect the storage amount of the almond paste of the first particle size in the buffer unit 140, and the present application does not impose any limitation in this regard.

[0047] In some embodiments, the sensor in the cache unit 140 for detecting the almond paste of the first particle size in the cache unit 140 can be communicatively connected to the control unit 130 via wired or wireless means, so that the control unit 130 can determine the storage amount of the almond paste of the first particle size in the cache unit 140 based on the sensor in the cache unit 140 for detecting the almond paste of the first particle size in the cache unit 140, and then control the first grinding device 110 to stop conveying the almond paste of the first particle size to the cache unit 140 when the storage amount of the almond paste of the first particle size in the cache unit 140 is greater than a first threshold value, and control the first grinding device 110 to convey the almond paste of the first particle size to the cache unit 140 when the storage amount of the almond paste of the first particle size in the cache unit 140 is less than a second threshold value.

[0048] In some embodiments, the first grinding device 110 is provided with a first fluid conveying device, and the first fluid conveying device in the first grinding device 110 is in communication with the control unit 130 via a wired or wireless connection, so that the control unit 130 can control the first grinding device 110 to deliver almond paste of the first particle size to the buffer unit 140 via the first fluid conveying device. For example, if the amount of almond paste of the first particle size stored in the buffer unit 140 is greater than a first threshold, the control unit 130 controls the first fluid conveying device to stop operating, so that the first grinding device 110 stops delivering the almond paste of the first particle size to the buffer unit 140; or, if the amount of almond paste of the first particle size stored in the buffer unit 140 is less than a second threshold, the control unit 130 controls the first fluid conveying device to start operating, so that the first grinding device 110 delivers the almond paste of the first particle size to the buffer unit 140.

[0049] Among them, the first fluid conveying equipment includes, for example, a positive displacement pump (such as a screw pump, a piston pump, etc.), a centrifugal pump (such as a single-stage centrifugal pump, a multi-stage centrifugal pump, a self-priming centrifugal pump, etc.), an axial flow pump (such as an axial flow pump, a mixed flow pump, etc.), etc. This application does not impose any restrictions in this regard.

[0050] Optionally, the control unit 130 is configured to control the cache unit 140 to deliver the almond paste of the first particle size to the second grinding device 120 when the storage capacity of the almond paste of the first particle size in the cache unit 140 exceeds a third threshold. The value of the third threshold can be set based on the actual capacity of the cache unit 140, and this application does not impose any limitation in this regard.

[0051] As described above, the sensor in the buffer unit 140 for detecting the almond paste of the first particle size in the buffer unit 140 can be communicatively connected to the control unit 130 via a wired or wireless communication mechanism, so that the control unit 130 can determine the storage amount of the almond paste of the first particle size in the buffer unit 140 based on the sensor in the buffer unit 140 for detecting the almond paste of the first particle size in the buffer unit 140. In view of this, in some embodiments, the control unit 130 can control the buffer unit 140 to deliver the almond paste of the first particle size to the second grinding device based on the storage amount of the almond paste of the first particle size in the buffer unit 140 if the storage amount of the almond paste of the first particle size in the buffer unit 140 is greater than a third threshold value.

[0052] In some embodiments, a second fluid conveying device is provided in the buffer unit 140, and the second fluid conveying device in the buffer unit 140 is communicatively connected to the control unit 130 via a wired or wireless communication method, so that the control unit 130 can control the buffer unit 140 to convey almond paste of the first particle size to the second grinding device 120 via the second fluid conveying device. For example, when the storage amount of almond paste of the first particle size in the buffer unit 140 exceeds a third threshold, the control unit 130 controls the second fluid conveying device to start operating, so that the almond paste of the first particle size is conveyed from the buffer unit 140 to the second grinding device 120.

[0053] Among them, the second fluid conveying equipment includes, for example, a volumetric pump (such as a screw pump, a piston pump, etc.), a centrifugal pump (such as a single-stage centrifugal pump, a multi-stage centrifugal pump, a self-priming centrifugal pump, etc.), an axial flow pump (such as an axial flow pump, a mixed flow pump, etc.), etc. This application does not impose any restrictions in this regard.

[0054] In the above method, when the amount of almond paste of the first particle size stored in the buffer unit 140 exceeds a first threshold, the control unit 130 may control the first grinding device 110 to stop supplying the almond paste of the first particle size to the buffer unit 140, thereby ensuring that the buffer unit 140 can provide sufficient buffer space. When the amount of almond paste of the first particle size stored in the buffer unit 140 is less than a second threshold, the control unit 130 may control the first grinding device 110 to supply the almond paste of the first particle size to the buffer unit 140, thereby ensuring that the amount of almond paste of the first particle size stored in the buffer unit 140 can meet the downstream demand of the buffer unit 140. When the amount of almond paste of the first particle size stored in the buffer unit 140 is greater than a third threshold, the control unit 130 may control the buffer unit 140 to supply the almond paste of the first particle size to the second grinding device, thereby ensuring that the buffer unit 140 can provide sufficient buffer space and that the second grinding device 120 can operate normally.

[0055] In order to save energy and reduce the energy consumption of the grinding system, the first grinding device 110 can be used to transport the almond paste of the first particle size to the buffer unit 140 by utilizing the gravity of the almond paste of the first particle size. Figure 1 As shown, the same is true below and will not be repeated) are arranged in sequence so that the almond paste of the first particle size in the first grinding device 110 can fall into the buffer unit 140 under the action of gravity.

[0056] When the first grinding device 110 and the cache unit 140 are arranged in sequence along the direction of gravity, the first shell of the first grinding device 110 is, for example, a funnel-shaped first shell, and the funnel-shaped first shell includes a first opening and a second opening, the diameter of the first opening is larger than the second opening, and the first opening and the second opening are arranged along the direction of gravity; the first sub-grinding disc and the second sub-grinding disc in the first grinding disc of the first grinding device 110 are, for example, arranged relatively to each other along the direction of gravity.

[0057] The control unit 130 is further configured to control the first grinding device 110 to stop grinding the almonds once if the amount of almond paste of the first particle size stored in the buffer unit 140 is greater than a first threshold value. The control unit 130 is further configured to control the first grinding device 110 to grind the almonds once if the amount of almond paste of the first particle size stored in the buffer unit 140 is less than a second threshold value. Because the first grinding device 110 and the buffer unit 140 are arranged sequentially along the direction of gravity, when the control unit 130 controls the first grinding device 110 to stop grinding the almonds once, no almond paste of the first particle size in the first grinding device 110 falls into the buffer unit 140. When the control unit 130 controls the first grinding device 110 to grind the almonds once, the almond paste of the first particle size in the first grinding device 110 can fall into the buffer unit 140.

[0058] Considering that in the actual production process of almond paste, the particle size requirements for the first and second almond pastes may vary in different production scenarios, in this embodiment of the application, the control unit 130 may further control the first grinding device 110 and the second grinding device 120 to adjust the particle sizes of the first and second almond pastes.

[0059] When the first grinding device 110 includes a first grinding disc, which includes a first sub-grinding disc and a second sub-grinding disc, the control unit 130 is further configured to control the distance between the first sub-grinding disc and the second sub-grinding disc according to a first preset parameter to adjust the particle size of the almond paste of the first particle size. The first preset parameter can be adjusted according to actual application scenarios, and this application does not impose any limitations in this regard.

[0060] When the second grinding device 120 includes a second grinding disc, which includes a third sub-grinding disc and a fourth sub-grinding disc, the control unit 130 is further configured to control the distance between the third sub-grinding disc and the fourth sub-grinding disc according to a second preset parameter to adjust the particle size of the almond paste of the second particle size. The second preset parameter can be adjusted based on actual application scenarios, and this application does not impose any limitations in this regard.

[0061] In some embodiments, the grinding system further comprises a storage device for receiving and storing the almond paste of the second particle size, such as a storage tank or any other device capable of storing the second almond paste.

[0062] In some embodiments, the grinding system further comprises a cooling device for cooling the almond paste of the second particle size before entering the storage device. The cooling device is, for example, a spiral scraper, or any other device capable of cooling the almond paste of the second particle size.

[0063] In some embodiments, the polishing system further includes a cleaning device for cleaning at least one of the first polishing device 110, the second polishing device 120, and the buffer unit 140. The control unit 130 is further configured to control the cleaning device to clean at least one of the first polishing device 110, the second polishing device 120, and the buffer unit 140 according to the production stage of the polishing system.

[0064] Figure 2 Schematic diagram of another almond grinding system provided in an embodiment of the present application. Figure 2 The almond grinding system provided in the embodiment of the present application includes a first grinding device 210, a second grinding device 220, a control unit 230, a cache unit 240, a cooling device 250 and a storage device 260.

[0065] It should be noted that Figure 2The almond grinding system shown in Figure 1 Another implementation of the almond grinding system shown in Figure 2 The first grinding device 210, the second grinding device 220, the control unit 230, the buffer unit 240 and the Figure 1 The first grinding device 110, the second grinding device 120, the control unit 130, and the cache unit 140 shown in FIG. 1 have the same principles, and the same contents are not repeated here.

[0066] like Figure 2 As shown, when the almond grinding system includes a cooling device 250 and a storage device 260, the almond paste of the second particle size in the second grinding device 220 can be cooled in the cooling device 250 before entering the storage device 260 to prevent the almond paste of the second particle size in the storage device 260 from being overheated and affecting the quality of the almond paste of the second particle size in the storage device 260. The second grinding device 220, the cooling device 250, and the storage device 260 can be connected by a pipeline, so that the almond paste of the second particle size in the second grinding device 220 can enter the cooling device 250 for cooling, and the cooled almond paste of the second particle size in the cooling device 250 can enter the storage device 260 for storage.

[0067] The almond grinding system provided in the application embodiment can realize the automation of almond grinding and reduce the hygiene risk of almonds during the grinding process by setting a first grinding device and a second grinding device, connecting the first grinding device and the second grinding device through a cache unit, and controlling the circulation of almond paste of the first particle size between multiple devices through a control unit. On the one hand, it can realize the automation of almond grinding and reduce the hygiene risk of almonds during the grinding process. On the other hand, it can also split the almond grinding process so that the almonds can be ground more fully. At the same time, the cache device ensures the continuity of the almond grinding system production, avoiding the production stagnation that may occur when the grinding speeds of the first grinding device and the second grinding device are different.
