Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant protein separation and recycling technology, and in particular to a device for separating protein powder from potato juice. Background Technology
[0002] In the field of potato deep processing, the separation and extraction of protein powder is a key step in enhancing product added value. Juice separation, as a pre-process for protein powder extraction, directly impacts the quality and production efficiency of the protein powder due to the performance of the equipment used. Devices for separating potato juice into protein powder are the core technology for achieving efficient and precise juice separation, and are of great significance for optimizing the potato protein powder production process.
[0003] Currently, most potato juice separation devices on the market use traditional sieving technology. Common mechanical structures include a fixed screen and a simple vibrating motor drive system. The vibrating motor directly drives the screen to vibrate at high frequency, causing the potato juice raw material to be sieved. The size of the screen openings determines the initial solid-liquid separation and particle grading. Some devices, to enhance the sieving effect, also add inclined guide plates below the screen to guide the separated juice and particles into different collection areas.
[0004] However, traditional equipment lacks a buffering and adjustment mechanism for the vibration generated by the vibrating motor. The screen is subjected to excessive impact force during the screening process, which not only leads to easy damage to the screen and poor equipment operation stability, but also causes violent fluctuations in the screening process. It is difficult to accurately control the screening particle size. A large amount of raw materials that meet the standards cannot be screened out in time due to unstable screening, resulting in low screening efficiency and poor screening effect, which seriously affects the subsequent processing quality and production efficiency of potato juice protein powder. Utility Model Content

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 - Figure 5 An embodiment of this utility model provides: a device for separating protein powder from potato juice, including a filter chamber 1, a motor 3 fixedly connected inside the filter chamber 1, a rotating rod 4 fixedly connected to the output end of the motor 3, a fixed frame 5 fixedly connected inside the filter chamber 1, the outer wall of the rotating rod 4 rotatably connected to the inside of the fixed frame 5, an eccentric shaft 6 fixedly connected to the outer wall of the rotating rod 4, a sieve plate 7 slidably connected to the outer wall of the eccentric shaft 6, a buffer assembly provided on the lower surface of the sieve plate 7, a guide plate 12 fixedly connected inside the filter chamber 1, a storage box 13 provided at the bottom of the filter chamber 1, a support frame 14 fixedly connected to the lower surface of the filter chamber 1, and a vertical centrifuge 20 connected to the output port of the filter chamber 1 through a pipe;
[0027] The buffer assembly includes a buffer spring 11, a telescopic rod 10 is fixedly connected to the lower surface of the screening plate 7, a support 9 is fixedly connected to the bottom of the telescopic rod 10, the lower surface of the support 9 is fixedly connected to the inside of the filter chamber 1, the buffer spring 11 is sleeved on the outer wall of the telescopic rod 10, one end of the buffer spring 11 is fixedly connected to the lower surface of the screening plate 7, and the other end of the buffer spring 11 is fixedly connected to the upper surface of the support 9.
[0028] Specifically, when using the device for separating protein powder from potato juice, motor 3 drives rotating rod 4 to rotate within fixed frame 5, which in turn drives eccentric shaft 6 to apply pressure to screening plate 7, causing it to shake. The buffer spring 11 above support 9 acts as a buffer, not only reducing the impact force of the shaking screening plate 7 but also making its shaking more stable, thus ensuring effective screening of the potato juice raw material. Raw material meeting the standards enters storage box 13 via guide plate 12, ensuring the screening effect, and is finally further separated by vertical centrifuge 20.
[0029] Reference Figure 1 - Figure 5A feed plate 15 is fixedly connected to the upper surface of the filter chamber 1. A discharge plate 2 is fixedly connected to the bottom of the feed plate 15. A motor 16 is fixedly connected to the upper surface of the filter chamber 1. A concave wheel 17 is fixedly connected to the output end of the motor 16. The outer wall of the concave wheel 17 is rotatably connected to the inside of the feed plate 15. A crushing roller 8 is fixedly connected to the inside of the concave wheel 17. Both ends of the crushing roller 8 are rotatably connected to the inside of the feed plate 15. A transmission belt 18 is provided on the outer wall of the concave wheel 17. The outer wall of the transmission belt 18 is rotatably connected to the inside of the feed plate 15. A concave wheel 19 is provided on the inner wall of the transmission belt 18. The outer wall of the concave wheel 19 is rotatably connected to the inside of the feed plate 15.
[0030] Specifically, placing the potato juice raw material on the feed plate 15 ensures its even distribution during subsequent processing, guaranteeing production efficiency and product quality. Motor 2 16 drives concave wheel 17 to rotate. Concave wheel 17, a crucial transmission component, is connected to concave wheel 2 19 via a transmission belt 18, causing the crushing rollers 8 on both sides to rotate synchronously, efficiently completing the crushing process. The crushed potato juice raw material is then transformed into smaller particles, which are fed through the feed plate 2 into the screening plate 7, forming a continuous processing flow and significantly improving the production efficiency of potato juice protein powder. Through ingenious structural design and coordinated operation, the entire device achieves efficient and stable operation from raw material pretreatment to screening, providing a reliable guarantee for the production of potato juice protein powder.
[0031] Working principle: When the device for separating protein powder from potato juice is needed, the rotating rod 4 rotates inside the fixed frame 5 under the drive of motor 3, which in turn pushes the eccentric shaft 6 to apply pressure to the screening plate 7. The screening plate 7 under pressure therefore shakes. The buffer spring 11 above the support 9 buffers the shaking, making the shaking of the screening plate 7 more stable. In this process, the role of the buffer spring 11 is crucial. It can not only reduce the impact force generated by the shaking of the screening plate 7, but also enable the screening plate 7 to effectively screen the potato juice raw material during stable shaking, ensuring the stability and accuracy of the screening process. The potato juice raw material that meets the screening standard enters the storage box 13 through the guide plate 12, ensuring the achievement of the screening effect. Finally, it is separated by the vertical centrifuge 20.
[0032] In addition, the potato juice raw material is placed inside the feed plate 15 to ensure that the potato juice raw material can be evenly distributed in the subsequent processing, thereby ensuring production efficiency and product quality. Next, the output end of the motor 16 drives the concave wheel 17 to rotate. The concave wheel 17 is an important transmission component, which transmits power to the crushing roller 8 to start rotating. While the concave wheel 17 is rotating, the transmission belt 18 also plays a crucial role. It connects the concave wheel 17 and the concave wheel 19, so that the concave wheel 19 can also rotate synchronously. The crushing rollers 8 on both sides can perform crushing work at the same time, which greatly improves production efficiency. After crushing, the potato juice raw material will be crushed into smaller particles, and the particles are smoothly fed into the screening plate 7 through the feed plate 2.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
