Embodiment for Carrying out the Invention

[0017] To make the object, technical solution and advantages of the present invention clearer and more definite, the present invention will be described in more detail below with reference to the drawings and by way of examples. It should be understood that the specific examples described in this specification are only used to explain the present invention and are not intended to limit the present invention. First Embodiment

[0018] As shown in FIGS. 1 to 7, the peanut powder processing apparatus provided by the present invention includes a processing chamber 10, a peeling and crushing assembly 20, an air flow supply assembly 30, and a grinding assembly 40. The processing chamber 10 has a material supply port 11 provided on the upper side, a peeling port 12 on the side, and a material discharge port 13 at the bottom. The peeling and crushing assembly 20 is provided in the middle part of the processing chamber 10 and has a first grinding roller 21 and a second grinding roller 22 installed opposite to each other, and an adjustment member for adjusting the interval between the first grinding roller 21 and the second grinding roller 22. The air flow supply assembly 30 has an air pump 31 communicating with the processing chamber 10 and an air flow supply passage 32, and supplies air flow into the processing chamber 10 to make the peanut grains in a floating state and continuously contact the first grinding roller 21 and the second grinding roller 22. The grinding assembly 40 is provided below the material discharge port 13 of the processing chamber 10 and has grinding rollers 41 installed opposite to each other.

[0019] The production method of peanut powder using the peanut powder processing apparatus of this embodiment includes the following steps. Peanut grains to be processed are fed into the processing chamber 10 from the material supply port 11, and the air flow supply assembly 30 continuously supplies dry air flow into the processing chamber 10 via the air pump 31, so that the peanut grains are in a dry state due to the dry air flow. Next, the air flow rate of the air flow is increased to blow up the dry peanut grains, and the floating peanut grains are intermittently brought into contact with the rotating first grinding roller 21 and the second grinding roller 22, thereby achieving peeling of the peanut grains, and the peeled peanut skins are blown out from the peeling opening 12. The peanut grains pass through the intermediate position between the first grinding roller 21 and the second grinding roller 22 and are crushed thereinto to become crushed materials of the peanut grains, and the peanut skins remaining on the peanut grains are further peeled off. The crushed materials of the peanut grains fall from the material discharge port 13 to the grinding assembly 40 below, and the peanut grains are repeatedly rolled and crushed during the rotation of the grinding roller 41 to form peanut powder.

[0020] In the processing chamber 10, first, the peanut grains are baked, then the peanut skins are removed by the peeling operation, and the first grinding roller 21 and the second grinding roller 22 are adjusted to achieve adjustment of their intervals. In this way, the fallen peanut grains are preliminarily crushed, so that the peanut skins that have not been peeled are completely peeled off, while being preliminarily crushed to facilitate subsequent grinding. When the preliminarily crushed peanut grains are dropped into the grinding assembly 40 and the grinding is completed, peanut powder can be obtained.

[0021] More specifically, by providing the processing chamber 10, the peanut grains to be processed are continuously or intermittently fed from the material supply port 11 into the interior of the processing chamber 10. Next, the peeling operation is performed in the processing chamber 10 by the peeling and crushing assembly 20, that is, the peeling process of the peanut grains is achieved by the two grinding rollers 21 / 22. After the peeling process is completed, the adjustment member achieves the adjustment between the grinding rollers 21 / 22. In this way, while moving the peanut grains downward and crushing them, the purpose of preliminarily crushing the peanut grains is achieved, which is advantageous for the subsequent grinding operation and improves the working efficiency. Furthermore, the airflow supply assembly 30 supplies airflow to keep the peanut grains with the skin peeled in a floating or rolling state while drying them, so that the peanut grains are uniformly contacted with the grinding rollers 21 / 22, achieving a good peeling effect. Finally, the peanut grains that have completed peeling and preliminary crushing are quickly ground in the grinding assembly 40 provided below to obtain peanut powder. Optionally, a grinding assembly 40 of an appropriate specification is selected to control the grinding level of the peanut powder. For example, it may be selected that the fineness becomes about 7 μm. Second Embodiment

[0022] Based on the first embodiment, the adjustment member of this embodiment includes an adjustment screw rod 62 and a moving base 63. The adjustment screw rod 62 is attached to the moving base 63 by a fixing plate 64. The adjustment screw rod 62 has a driving handle 65 at its outer end. At the inner end of the moving plate 631 of the moving base 63, the first grinding roller 21 is rotatably provided through the processing chamber 10. One end of the first grinding roller 21 is connected to a driven bevel gear 66. It further includes a driving motor 67, a driving belt 68, and a driving main rod 71 that are sequentially connected. The driving main rod 71 has a slider 72 and a driven bevel gear 73. A main bevel gear 69 is provided on the slider 72. The slider 72 is slidably fitted to a protrusion 74 of the driving main rod 71. The main bevel gear 69 meshes with the driven bevel gear 66. The slider 72 is connected to the moving gantry 63 via a linkage plate 721. One end of the second grinding roller 22 meshes with the driven bevel gear 73 via an interlocking bevel gear. Specifically, as shown in FIG. 7, the first grinding roller 21 is rotatably provided on a vertical mounting plate of the moving gantry 63, thereby achieving the movement of the first grinding roller 21 together with the moving gantry 63.

[0023] The production method of peanut powder using the peanut powder processing device of this embodiment includes the following steps. When it is necessary to adjust the distance between the first grinding roller 21 and the second grinding roller 22, the following steps are executed. Drive the drive handle 65 to rotate, move the fixed plate 64 axially, correspondingly drive the moving gantry 63 to move, drive the first grinding roller 21 and the linkage plate 721 on the moving gantry 63 to move simultaneously, correspondingly move the driving main rod 71 to the slider 72 and the main bevel gear 69, and drive while keeping the main bevel gear 69 and the driven bevel gear 66 meshed. Also, drive the driving motor 67 to sequentially drive and rotate the driving belt 68 and the driving main rod 71. Correspondingly, drive and move the driven bevel gear 66 and the interlocking bevel gear by the main bevel gear 69 and the driven bevel gear 73 respectively. Correspondingly, rotate the first grinding roller 21 and the second grinding roller 22. Example 3

[0024] Based on the above embodiments, there is a secondary recovery passage 15 on the side of the processing chamber 10 of this embodiment, with the upper end connected to the peeling opening 12. At the position of the peeling opening 12, there is an opening and closing structure 90 having an opening and closing cylinder 91 and an opening and closing plate 92 for selectively closing the peeling opening 12. The outer end of the secondary recovery passage 15 is connected to a recovery pipeline 35 and a recovery chamber 36. The lower end of the secondary recovery passage 15 is connected to an inclined passage 34, and the inclined passage 34 communicates with the air flow supply passage 32. The inclined passage 34 is provided with a stop plate 16 hinged to the telescopic rod of a stop cylinder 18 via a rotating piece 17.

[0025] The production method of peanut powder using the peanut powder processing device of this embodiment includes the following steps. After the crushed peanut grains exit from the material discharge port 13, they move to the grinding assembly 40 below. At this time, the air flow from the side is blown again onto the peanut grains moving downward, thereby removing the peanut skins again. The peanut skins enter into the recovery pipeline 35 and the recovery chamber 36 along the inclined passage 34 and the secondary recovery passage 15 provided on the side. And the stop cylinder 18 moves the rotating piece 17 via the telescopic rod by telescoping, and correspondingly, the stop plate 16 achieves the opening and closing of the inclined passage 34. Example 4

[0026] In a more preferable solution, as shown in FIG. 8, at the position of the material discharge port 13, there is a blocking sheet 131 having a blowing hole 132. The blocking sheet 131 is connected to a push-pull cylinder 133 and is used to selectively close the material discharge port 13.

[0027] Further, the side wall of the processing chamber 10 has a guide groove 25, and the connecting shaft 26 between the driven bevel gear 66 and the first grinding roller 21 is movably provided in the guide groove 25. Preferably, the air flow supply assembly 30 further includes a heating unit for supplying heat to the air flow supply passage 32. That is, as the heating unit, for example, an electric heating wire is selected, and an air flow is supplied to the air flow supply passage 32 by an air pump while heat is supplied to form a heated air flow. In this way, the peanut grains can be dried better, which is advantageous for the peeling process.

[0028] The production method of peanut powder using the peanut powder processing apparatus of this embodiment includes the following steps. The push-pull cylinder 133 expands and contracts. Correspondingly, the blocking sheet 131 blocks or opens the material discharge port 13. When the material discharge port 13 is blocked, the air flow can enter the processing chamber 10 through the air outlet 132. By providing the blocking sheet 131, the falling of the peanut grains in the processing chamber 10 is delayed. When it is necessary to drop the material, the blocking sheet 131 is opened to complete the dropping of the material.

[0029] As shown in FIG. 9, below the inclined passage 34, a peanut oil pressing assembly 60 including a fixing plate 61, a hydraulic cylinder 62, and a pressing plate 63 is provided. The hydraulic cylinder 62 is provided on the fixing plate 61, and the telescopic rod of the hydraulic cylinder 62 is connected to the pressing plate 63. A vertical fixed baffle 64 is provided at an intermediate position below the inclined passage 34. A material receiving passage 65 is formed between the vertical fixed baffle 64 and the pressing plate 63. The grinding assembly 40 is provided below the material receiving passage 65, and a control valve 66 is provided below the material receiving passage 65.

[0030] When the peanut grains move to the material receiving passage 65, the control valve 66 stops the continuous downward movement of the peanut grains, and the hydraulic cylinder 62 drives the pressing plate 63 to move laterally. Thereby, the peanut grains are sandwiched and pressed between the pressing plate 63 and the vertical fixed baffle 64, and the peanut oil gradually oozes out. Subsequently, open the control valve 66, collect and utilize the peanut oil flowing out from the pulverizing assembly 40 below, and perform subsequent pulverization on the solid matter.

[0031] In another preferred embodiment, the first pulverizing roller 21 and the second pulverizing roller 22 are each independently drivingly connected by a driving motor, and the driving motor and the first pulverizing roller 21 are integrally connected to an electric telescopic rod or an adjusting cylinder. In this way, the first pulverizing roller 21 can be driven to move horizontally, and the distance between the first pulverizing roller 21 and the second pulverizing roller 22 can be adjusted. In this way, it is not necessary to provide the structure adjusted by the above screw rod.

[0032] In a more preferred embodiment, the blocking sheet has ventilation holes, and the distance between the first pulverizing roller 21 and the second pulverizing roller 22 and the blocking sheet 131 provided at the bottom is less than 10 cm, or less than 5 cm. In this way, in one embodiment, when the peanut grains on the blocking sheet contact the pulverizing roller 21 / 22, they are crushed to obtain peanut grains having a desired particle size. The peanut grains that meet the particle size requirements are discharged downward from the blowing holes 132 of the blocking sheet 131. If necessary, an air flow is supplied by the blocking sheet 131. In this way, it is possible to avoid clogging by piercing through the blowing holes 132 with the air flow, and the magnitude of the air flow can also be adjusted. If necessary, the peanut grains can be suspended. In this way, the peanut grains are in a suspended state or intermittently suspended, and can better contact the pulverizing roller and be crushed. By supplying the air flow multiple times, the peanut grains on the blocking sheet 131 are uniformly and repeatedly brought into contact with the pulverizing roller to achieve the purpose of uniform crushing. In some embodiments, when the predetermined particle size requirement is met, the blocking sheet 131 is directly removed to discharge the peanut grains.

[0033] The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make some improvements and changes without departing from the technical principle of the present invention, and these improvements and changes should also be regarded as within the protection scope of the present invention.
