Abstract
Description
Technical Field
[0001] This utility model relates to the field of cottonseed high-protein production and processing technology, and in particular to a cottonseed kernel recycling device in the production of high-protein cottonseed. Background Technology
[0002] Cottonseed, as an important component of plant resources, plays an irreplaceable role in the food and feed industries. Its rich protein content provides a solid material basis for improving the quality of food and feed, and it has been widely used in related industries, becoming an indispensable element.
[0003] However, numerous challenges exist in the processing of high-protein cottonseed. The amount of cottonseed hulls within the cotton kernel directly impacts protein quality and yield. In actual processing, many companies often face difficulties due to technological or equipment limitations in the crucial cleaning process of cottonseed hulls and kernels, in order to obtain high-quality high-protein cottonseed. A large number of small cottonseeds and some kernels inevitably escape from the cottonseed hulls; these resources, which should be fully utilized, are discarded, leading to a reduced protein yield and significant resource waste. This is undoubtedly an improper handling of valuable plant resources.
[0004] Furthermore, some companies reduce the gap between the hulling rollers during the crushing and hulling process to minimize cotton hull contamination. While this reduces hull contamination, it leads to excessive crushing of the cottonseed during the crushing process, increasing the powder content. During the crushing and cleaning stage, a large amount of yellow hulls is discharged, making processing difficult, and it also carries a significant amount of protein powder, further reducing the protein yield and increasing production costs and processing complexity.
[0005] Therefore, effectively reducing cottonseed breakage and powderiness during the crushing and hulling process, while minimizing the emission of cottonseed and kernel from the cotton husks to improve protein quality and yield, has become a critical issue that urgently needs to be addressed in the high-protein processing of cottonseed. Solving this problem not only affects the economic benefits of enterprises but also involves the overall situation of rational resource utilization and sustainable development. Only by finding effective solutions can cottonseed, an important plant resource, realize its maximum value in the food and feed industries and achieve its potential economic and ecological benefits.

[0032] Example 1: Referring to all the accompanying drawings; a device for recycling cotton kernels from cottonseed hulls in high-protein cottonseed production, characterized in that,
[0033] The device includes a bent housing 1, with an air outlet connecting flange 8 above the bent housing 1, and a rectangular feed chute 7 arranged at an inclination on the bent housing 1.
[0034] The inlet on the rectangular feed chute 7 is capable of receiving materials;
[0035] The air outlet connecting flange 8 can connect to the suction supply structure. The substantive technical effects and implementation process of the technical solution here, i.e., its basic functions, are as follows:
[0036] Please refer to Figure 1 This utility model provides a technical solution: a device for recycling cottonseed and cotton kernels from cottonseed hulls in high-protein cottonseed processing, including a feeding device, a discharge device, and an air regulating device;
[0037] The feeding device includes a flange connecting plate, on which a rectangular feeding trough is fixedly connected. A feeding conveyor is fixed to the upper part of the rectangular feeding trough. The rectangular feeding trough is used to receive and guide cotton hull raw materials into the recycling system. The unloading device includes a bending shell, on which an air outlet connecting flange is fixed. A negative pressure fan is connected to the upper part of the air outlet connecting flange via an air duct. An air regulating device is fixed to the lower side of the bending shell. The regulating screw and hinge of the air regulating device are fixed to the lower side of the bending shell. The hinge is fixedly connected to an air regulating plate. The airflow is controlled by an adjusting nut 4 at the upper part of the air regulating plate. The lower part of the bending shell is the unloading port.
[0038] The air conditioning device adjusts the cross-sectional area of the air inlet of the baffle plate according to the amount of small cotton seeds and kernels in the cotton hull. This precisely controls the airflow and optimizes the effect of the small cotton seeds and kernels.
[0039] The usage method is as follows: Before recycling, the cotton hull raw material enters the rectangular feeding trough through the conveying equipment. The cotton hull containing cottonseed slides evenly into the bending shell. The bending shell bounces the falling cotton hull containing cottonseed evenly, separating the cottonseed from the cotton hull. The lighter cotton hull is conveyed upward by the negative pressure fan. During the cotton hull conveying process, it is blocked by the bending body. The heavier small cottonseeds and cotton kernels continue to fall. During the fall, they are repeatedly bounced by the bending shell, and the small cottonseeds and cotton kernels are separated from the cotton hull multiple times. The negative pressure fan conveys the lighter cotton hull upward again. Finally, the small cottonseeds and cotton kernels fall into the lower conveying device and enter the next process through the conveying equipment. The cotton hulls are unloaded through the matching cyclone and closed-loop discharge valve and then conveyed into the cotton hull room through the conveying equipment.
[0040] The bending shell evenly bounces up the cotton hull material falling from the feeding device, separating the cotton hulls from the small cotton seeds and kernels. The lighter cotton hulls are then conveyed upwards by negative pressure airflow. As the cotton hulls rise, they are repeatedly blocked by the bending shell, while the heavier small cotton seeds and kernels continue to fall. During their fall, the cotton seeds and kernels are repeatedly bounced up by the bending shell, separating from the cotton hulls multiple times. The negative pressure fan then conveys the lighter cotton hulls upwards again. Finally, the cotton kernels, after being cleaned of their hulls, fall into the lower conveying device. This equipment significantly reduces the proportion of small cottonseeds and kernels in cotton hulls through processing. The synergistic action of the feeding, unloading, and air-regulating devices maximizes the content of cottonseeds and kernels in the hulls, thereby improving the quality and yield of high-protein cottonseed and meeting the standards for high-quality cottonseed protein processing. Furthermore, the reprocessing unit allows for adjustment of the gap between the shelling rollers during crushing and shelling, greatly reducing the powder content. This plays a crucial role in improving the quality of subsequent processing steps, such as oil and protein extraction, while also reducing resource waste, increasing the yield of white protein, and enhancing the company's economic benefits.
[0041] Example 2: As a further improvement, parallel, or optional independent solution, an air regulating plate 3 connected by a hinge 2 is arranged at a lower position of the bent housing 1. A lead screw 5 passes through the air regulating plate 3, and the lead screw 5 passes through a nut 4. Rotating the lead screw 5 adjusts the opening degree of the air regulating plate 3. The end of the lead screw 5 is rotatably located on the bent housing 1. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: This provides a method for adjusting the opening size; a gate valve can also be used instead.
[0042] Example 3: As a further improvement, parallel, or optional independent solution, the air outlet connecting flange 8 is a centrifugal fan. The centrifugal fan is a dust-exhausting centrifugal fan. A matching cyclone separator and a closed-loop discharge valve are also connected behind the dust-exhausting centrifugal fan for unloading. The opening below the bent housing 1 connects to the lower conveying device. The bending of the bent housing 1 comprises multiple sections. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: therefore, it can achieve multiple bending and separation.
[0043] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.
