Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing and food machinery technology, and in particular to a flaxseed dehulling device. Background Technology

[0002] Flaxseed is rich in linolenic acid, lignans and dietary fiber, and has high nutritional value. However, its outer layer is a hard, lignified seed coat, which has a poor taste and is not easy to digest when eaten directly. It needs to be dehulled to obtain pure kernels.

[0003] In existing technologies, such as Chinese patent application CN202122717272.1, a flaxseed dehulling device addresses the problem that, due to the small size of flaxseeds, a large portion of the kernels cannot be separated from the shell after dehulling, resulting in a mixture of separated kernels and unseparated seeds. The proposed solution includes a dehulling tank and a separation box. The bottom of the separation box is fixedly connected to a first conduit and a second conduit, which are connected to the separation box. In this invention, a filter screen is used to allow the flaxseed kernels to fall into a flaxseed kernel collection box for collection, facilitating the separation of kernels from unsellted seeds and improving work efficiency. A rotating block and filter screen cause the filter screen to vibrate, preventing clogging. A protective shell protects the first and second gears.

[0004] While the above solutions have the advantages mentioned above, their disadvantages are as follows: some equipment uses traditional crushing or impact-type dehulling, which can easily lead to kernel breakage. The dried flaxseeds are not pre-treated, thus affecting the oil yield and product quality. Therefore, these issues need to be addressed. Utility Model Content

[0043] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0045] Example 1, such as Figure 1-4 As shown, the dehulling structure is located inside the processing box 1, including symmetrically arranged chutes 101 for adjusting the position of the slide; a guide plate 103 is located on the inner top wall of the processing box 1 for guiding the flaxseed material to fall and prevent blockage; a mounting frame 102 is fixed to the surface of the processing box for supporting the drive system; the processing structure includes a ripening chamber 2, fixed to the top of the processing box, with a feeding port 205 on its top, and a heating coil 201 wound inside the chamber to perform low-temperature ripening treatment of the flaxseed at 60-80℃. This equipment achieves efficient and low-damage dehulling of flaxseed through ripening and softening, significantly improving the dehulling rate and subsequent processing quality.

[0046] In this embodiment, flaxseed raw materials are fed into the feeding port 205, and a water pipe is connected to the connection port 203. Water mist is injected into the maturation chamber 2 through the nozzle 2031 to soften the flaxseed shells. At the same time, the heating coil 201 heats the flaxseeds, and the second drive motor 206 is started. The second gear 2061 drives the first gear 2021 to slowly rotate the drive shaft 202 and the stirring rod 207 to stir the flaxseeds and prevent clumping. When the receiving cavity 2023 on the surface of the rotating disk 2022 coincides with the discharge port 204, the material is discharged intermittently. By performing short-term humidity adjustment and temperature control maturation on the flaxseeds, the shelling intensity is reduced and kernel loss is minimized.

[0047] Example 2, as Figure 1-4 As shown, the stepper motor 1021 is detachably mounted on the surface of the mounting bracket 102 via the frame, and its output end is connected to the bidirectional lead screw 1022; two slides 1011 are threaded onto the symmetrical sections of the bidirectional lead screw 1022, with one end slidingly embedded in the slide groove 101; two rotating shafts 1013 are bearing-connected between the two slides 1011, with one end driven by the drive motor 1012, and the outer surface of the shaft is fixed with the shelling roller 1014; the top of the curing chamber 2 is symmetrically provided with connection ports 203, and nozzles 2031 are installed on its side for adding... The bottom is symmetrically equipped with discharge ports 204; the drive shaft 202 is vertically installed in the bin, and the top gear 2021 meshes with the gear 2061 at the output end of the drive motor 206. The bottom is equipped with a stirring rod 207 and a rotating disk 2022 with a receiving cavity 2023. This structure achieves synchronous and precise adjustment of the gap of the shelling roller 1014 through the stepper motor driving the bidirectional lead screw 1022, which can adapt to raw materials of different particle sizes and at the same time meet the effect of intermittent feeding, preventing continuous feeding from affecting the shelling work.

[0048] In this embodiment, the guide plate 103 guides the intermittently discharged flax seeds, and the drive motor 1012 is started to drive the rotating shaft 1013 inside the slide 1011. The hulling rollers 1014 on the surface hull the flax seeds. When the stepper motor 1021 on the surface of the drive mounting frame 102 is driven, the bidirectional lead screw 1022 at the output end drives the slide 1011 on the surface to move along the center of the slide groove 101. The distance between the two hulling rollers 1014 is adjusted to adapt to different seed sizes and improve the applicability of the device.

[0049] Working principle: During use, flaxseed raw materials are fed into the feeding port 205, and a water pipe is connected through the connection port 203. Water mist is injected into the maturation chamber 2 through the nozzle 2031, softening the flaxseed shells. Simultaneously, the heating coil 201 heats the flaxseeds, activating the second drive motor 206. Through the second gear 2061, the first gear 2021 is driven, causing the drive shaft 202 and the stirring rod 207 to rotate slowly, stirring the flaxseeds and preventing clumping. When the receiving cavity 2023 on the surface of the rotating disc 2022 coincides with the discharge port 204, the material is intermittently discharged. Short-term humidity and temperature control ripening reduces shelling intensity and kernel loss. In addition, the guide plate 103 guides the intermittently discharged flax seeds. The drive motor 1012 is started to drive the rotating shaft 1013 inside the slide 1011, which works in conjunction with the shelling rollers 1014 on the surface to shell the flax seeds. When the stepper motor 1021 on the surface of the drive mounting frame 102 is driven, the bidirectional lead screw 1022 at the output end drives the slide 1011 on the surface to move along the interior of the slide groove 101 to center. The distance between the two shelling rollers 1014 is adjusted to adapt to different seed sizes and improve the applicability of the device.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
