Description

Technical Field

[0001] This utility model relates to the technical field of plant protein extraction devices, specifically a pea protein extraction and separation device. Background Technology

[0002] Pea protein extraction and separation equipment is specifically designed for extracting protein from peas. Given the increasing demand for plant-based proteins, especially pea protein, which is gaining attention due to its superior amino acid composition and environmentally friendly production process, the importance of this type of equipment is becoming increasingly apparent. The pea protein extraction process typically begins by crushing or grinding the cleaned raw material. Then, an extraction solution with a specific pH value is mixed with the crushed raw material or slurry, allowing the protein to dissolve in the extraction solution, thereby achieving the purpose of protein extraction.

[0003] Patent CN221206884U discloses a soybean protein extraction and separation device, including a soaking tank for soybean protein extraction and separation. The lower end of the soaking tank is connected to a mixing and separation tank and a compression tank. A connecting pipe is fixedly connected between the soaking tank and the mixing and separation tank. An extraction liquid tank is fixedly connected to the top surface of the soaking tank. A water supply pipe is fixedly connected to the extraction liquid tank, and the end of the water supply pipe extends into the soaking tank. An inlet pipe and a motor are fixedly connected to the top surface of the soaking tank. The motor's rotating shaft extends into the soaking tank and is fixedly connected to a rotating rod. A turntable is fixedly connected to the lower end of the rotating rod. The lower end of the turntable slides against the bottom of the soaking tank, and strip plates are symmetrically fixedly connected to the upper end of the turntable. Multiple stirring blades are fixedly connected to the rod wall. This device can effectively and thoroughly mix the extraction liquid and soybeans in the soaking tank.

[0004] However, the extraction and separation device in the above technology still has the following problems: Although a rotatable turntable can be installed at the bottom of the soaking tank to ensure that the mixture at the bottom of the soaking tank is fully stirred and mixed, when the turntable is sealed to the bottom of the soaking tank by a sealing ring, the sealing ring needs to be tightly fitted to the bottom of the tank. This increases the resistance of the turntable when rotating at the bottom of the tank, increases the energy consumption of the stirring and mixing operation, and the friction between the sealing ring and the inner wall of the tank bottom may generate a large amount of wear debris during the continuous rotation and stirring process. These wear debris mixed into the solution will cause a certain degree of pollution to the solution in the soaking tank and affect the extraction quality of plant protein. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a pea protein extraction and separation device to improve the quality of protein extraction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pea protein extraction and separation device, comprising an extraction tank, the bottom of which is an inverted trapezoidal design, a stirring motor fixedly connected to the top of the extraction tank, the output shaft of the stirring motor penetrating downward into the extraction tank and connected to a stirring assembly, an extraction liquid tank and a raw material addition assembly also connected to the top of the extraction tank, the extraction liquid tank and the raw material addition assembly being located on both sides of the stirring motor respectively.

[0007] Furthermore, a drain pipe is fixedly connected to and connected to the bottom side wall of the inverted trapezoidal extraction tank, and a drain valve is installed on the drain pipe.

[0008] Furthermore, the raw material addition component includes an addition tube and an addition funnel. The addition tube is fixedly connected to the top of the extraction chamber and communicates with the extraction chamber. The addition funnel is fixedly connected to and communicates with the end of the addition tube away from the extraction chamber.

[0009] Furthermore, a liquid addition pipe is fixedly connected to and communicates with the top of the extraction tank, and an injection pipe is fixedly connected to and communicates with the bottom side wall of the extraction tank. The other end of the injection pipe passes downward through the top of the extraction tank and communicates with the extraction tank. A liquid addition valve is installed on the injection pipe.

[0010] Furthermore, one end of the injection tube that extends into the extraction chamber is fixedly connected to and connected to a nozzle.

[0011] Furthermore, the stirring assembly includes a shaft and several blades. One end of the shaft is fixedly connected to the end of the stirring motor output shaft that extends into the extraction chamber. Several blades are evenly distributed on the outside of the shaft, and all blades are fixedly connected to the shaft.

[0012] Furthermore, a conical block is fixedly connected to the inner wall of the inverted trapezoidal bottom of the extraction chamber.

[0013] Furthermore, a limiting hole is provided at the top center of the cone-shaped block, and the end of the shaft away from the stirring motor is rotatably connected to the limiting hole.

[0014] Furthermore, a trapezoidal base is fixedly connected to the bottom of the inverted trapezoidal extraction chamber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This pea protein extraction and separation device uses a stirring motor to agitate the mixture inside the extraction tank, causing it to flow slowly downwards from the top of the tank. When the mixture flows through the bottom of the extraction tank (designed as an inverted trapezoid), it creates an impact backflow. This backflow powerfully impacts and carries the solid-liquid mixture at the bottom of the extraction tank, causing it to flow upwards with the liquid backflow. In this way, the liquid inside the extraction tank achieves backflow mixing in the vertical direction, significantly enhancing the mixing effect between the extract and the protein raw material, thereby improving the protein extraction efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 4 A pea protein extraction and separation device includes an extraction tank 1 with an inverted trapezoidal bottom. A stirring motor 2 is fixedly connected to the top of the extraction tank 1. The output shaft of the stirring motor 2 extends downward into the extraction tank 1 and is connected to a stirring assembly. An extraction liquid tank 3 and a raw material addition assembly are also connected to the top of the extraction tank 1. The extraction liquid tank 3 and the raw material addition assembly are located on both sides of the stirring motor 2.

[0024] like Figures 1 to 4 As shown, the main improvement of this invention lies in enhancing the extraction and mixing effect of pea protein, such as... Figures 1 to 4As shown, in use, the pea protein extraction and separation device of this utility model starts the stirring motor 2, which drives the stirring component in the extraction tank 1 to stir the mixture inside the extraction tank 1, and makes the mixture flow from top to bottom. When the downward flowing mixture impacts the bottom of the extraction tank 1, due to the small diameter of the inverted trapezoidal bottom, a stronger impact effect is formed, thereby dispersing the solid-liquid mixture at the bottom of the extraction tank 1 and flowing back to the top of the extraction tank 1 with the reflux liquid. This achieves vertical reflux mixing of the liquid inside the extraction tank 1, which significantly enhances the mixing effect of the extract and the protein raw material, thereby improving the protein extraction efficiency. The extract tank 3 is used to store the extraction reagent and to add the extraction reagent to the extraction tank 1.

[0025] like Figure 1 and Figure 2 As shown, the bottom side wall of the inverted trapezoidal extraction tank 1 is fixedly connected to and connected to a drain pipe 4, and a drain valve 5 is installed on the drain pipe 4. After the extraction operation of fully mixing the extract and plant protein is completed, the drain pipe 4 can be opened through the drain valve 5 to drain the mixed liquid in the extraction tank 1 for the next separation operation. During the mixing process, closing the drain valve 5 can prevent the liquid inside the extraction tank 1 from flowing out, making it convenient to use.

[0026] like Figure 1 and Figure 2 As shown, the raw material adding assembly includes an adding tube 6 and an adding funnel 7. The adding tube 6 is fixedly connected to the top of the extraction chamber 1 and communicates with the extraction chamber 1. The adding funnel 7 is fixedly connected to and communicates with the end of the adding tube 6 away from the extraction chamber 1. When adding pea milk or powder to the extraction chamber 1, the raw material can be added into the adding funnel 7, and then the raw material falls down into the extraction chamber 1 along the adding tube 6. The adding funnel 7 can reduce the dripping of raw material during the adding process and improve the stability of the raw material adding operation.

[0027] like Figures 1 to 3 As shown, the top of the extraction tank 3 is fixedly connected to and connected to a liquid addition pipe 8, and the bottom side wall of the extraction tank 3 is fixedly connected to and connected to an injection pipe 9. The other end of the injection pipe 9 extends downward through the top of the extraction tank 1 and communicates with the extraction tank 1. A liquid addition valve 10 is installed on the injection pipe 9. Extraction solution can be added to the extraction tank 3 through the liquid addition pipe 8, and the liquid addition valve 10 can control whether the extraction solution in the extraction tank 3 is added to the extraction tank 1 through the injection pipe 9. The liquid addition valve 10 can be a solenoid valve to more precisely control the amount of extraction solution added to the extraction tank 1, avoiding waste due to over-addition or affecting the extraction effect due to insufficient addition.

[0028] like Figure 2 and Figure 4As shown, one end of the injection tube 9, which extends into the extraction tank 1, is fixedly connected to and communicates with a nozzle 11. Through the nozzle 11, when the injection tube 9 adds extractant to the extraction tank 1, the extractant can be sprayed into the raw material slurry within the extraction tank 1, preventing the extractant from adhering to the top inner wall of the extraction tank 1 and improving the extraction effect.

[0029] like Figures 1 to 4 As shown, the stirring assembly includes a shaft 12 and several blades 13. One end of the shaft 12 is fixedly connected to the other end of the output shaft of the stirring motor 2, which extends into the extraction tank 1. The blades 13 are evenly distributed on the outside of the shaft 12, and each blade 13 is fixedly connected to the shaft 12. The stirring motor 2 drives the shaft 12 to rotate, thereby causing the multiple blades 13 on the shaft 12 to rotate inside the extraction tank 1. While horizontally stirring the mixture inside the extraction tank 1, the upper layer of mixture is gradually squeezed downwards, thus forming an upward and downward reflux effect. It should be noted that a certain gap needs to be left between the blades 13 and the inner wall of the extraction tank 1 so that the mixture refluxing from the bottom of the extraction tank 1 can flow back upwards along the tank wall from the bottom of the extraction tank 1. Thus, while horizontally stirring, the reflux effect further improves the stirring effect of the mixture inside the extraction tank 1, improving the mixing and extraction effect and efficiency of the extract and pea milk.

[0030] like Figures 1 to 4 As shown, a conical block 14 is fixedly connected to the inner wall of the inverted trapezoidal bottom of the extraction tank 1. When the blade 13 drives the upper mixture downward, the conical block 14 at the bottom causes the downward-flowing mixture to impact the conical block 14 and then spread outward, creating an impact effect on the mixture at the bottom of the extraction tank 1. Ultimately, the mixture flows back upward along the inner wall of the extraction tank 1 after contacting the bottom of the extraction tank 1.

[0031] like Figure 2 and Figure 4 As shown, a limiting hole 101 is provided at the middle of the top of the conical block 14, and the end of the shaft 12 away from the stirring motor 2 is rotatably connected to the limiting hole 101. When the shaft 12 rotates rapidly under the drive of the stirring motor 2, the bottom of the shaft 12 can be limited through the limiting hole 101 at the top of the conical block 14, thereby preventing the shaft 12 from shaking during the rotation and stirring process, and improving the stability of the stirring process in the extraction tank 1.

[0032] like Figure 1 and Figure 2 As shown, a trapezoidal base 15 is fixedly connected to the bottom of the inverted trapezoidal shape of the extraction chamber 1. The trapezoidal base 15 increases the contact area between the bottom of the extraction chamber 1 and the ground, thereby preventing the extraction chamber 1 from tipping over during stirring and improving the stability and safety of the extraction operation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
