Description

Technical Field

[0001] The utility model relates to the field of plant protein liquid production, in particular to a high-pressure double homogenizing device used for plant protein liquid production. Background Art

[0002] The baking industry generally uses egg liquid to improve the brightness and water retention of baked products, but the traditional egg liquid method has shortcomings. It has high requirements for sanitary conditions during the production process, and there are problems such as easy breeding of bacteria and short shelf life. Compared with traditional egg liquid, plant protein liquid increases the shelf life of the product, does not contain cholesterol, has no unpleasant odor, and is more environmentally friendly and healthy. Plant protein liquid refers to a solution obtained by extracting protein from plant protein and mixing and emulsifying it with other ingredients. The production process of plant protein liquid often requires a high-pressure homogenization process to tear the dispersed phase into particles and disperse them in the continuous phase, and finally achieve the effect of homogenization and emulsification. However, plant protein liquid is a mixture of many different types of ingredients. To achieve a homogenized emulsified state similar to egg liquid, higher requirements are placed on the homogenization process. It is necessary to improve the homogenization effect of traditional high-pressure homogenization to produce more stable products. Summary of the invention

[0003] In order to solve the problems mentioned in the above background, the utility model provides a high-pressure double homogenization device for the production of plant protein liquid. In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows.

[0004] A high-pressure double homogenization device for producing vegetable protein liquid includes a plunger reciprocating pump system, a double homogenization mechanism, a base and a shell. The material is pressurized by the plunger reciprocating pump system and transported to the double homogenization mechanism for homogenization. The plunger reciprocating pump system and the double homogenization mechanism are installed on the base and the shell.

[0005] The plunger reciprocating pump system includes a material feed port, a plunger and a power mechanism, a pump body, a pressure regulating valve group, and a material discharge channel. The raw materials prepared and stirred according to the process requirements enter the plunger reciprocating pump system from the material feed port, the plunger and the power mechanism provide power to make the plunger reciprocate in the pump body, and the material passes through the valve group with adjustable gap size during transportation, generating high-pressure material with adjustable pressure, which is transported to the double homogenizing mechanism through the material discharge channel.

[0006] The double homogenization mechanism is composed of an impact homogenization unit and a convection collision homogenization unit. The material flows through the impact homogenization unit and the convection collision homogenization unit in sequence to complete the double homogenization.

[0007] The impact homogenization unit is composed of an impact homogenization feed channel, an impact valve seat, a homogenization valve core, an impact ring, an operating mechanism, and a conical pressurization channel. The impact homogenization feed channel is connected to the material discharge channel, and the material enters the impact homogenization unit through the impact homogenization feed channel. The homogenization valve seat, the homogenization valve core, and the impact ring are installed and fit together. There is a gap between the homogenization valve seat and the homogenization valve core, and the size of the gap is adjusted by operating the position of the homogenization valve core through the operating mechanism. The material is ejected at high speed from the adjustable gap and ejected after being impacted by the impact ring, generating cavitation effect, impact effect, and shear effect, thereby improving the degree of dispersion uniformity. The material then enters the conical pressurization channel, and the channel diameter changes from large to small, increasing the pressure lost by the material after impact homogenization.

[0008] The convection collision homogenization unit includes a convection homogenization feed port, an interaction cavity, and a convection homogenization discharge port. The convection homogenization feed port is connected to the conical pressurization channel. The pressurized material enters the interaction cavity through the convection homogenization feed port. The interaction cavity has a small aperture and is provided with a diversion channel, an interaction channel, and a collision cavity. After the material is divided into two directions in the diversion channel, it interacts again through the interaction channel and undergoes a strong high-speed collision in the hollow spherical collision cavity. The particle collision, cavitation, and turbulence in the fluid further increase the homogenization effect and release the pressure. The homogenized material then flows out from the convection homogenization discharge port.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] (1) The utility model adds a convection collision homogenization unit after high-pressure homogenization, so that the material is double homogenized, thereby improving the homogenization effect;

[0011] (2) Convection collision homogenization directly utilizes the high-pressure material after impact homogenization to provide pressure, and a conical pressurization channel is set up to increase the pressure lost after the material is impact homogenized.

[0012] (3) The pressure of the material is released in the collision chamber, and the material flows out smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and pea protein liquid embodiments.

[0020] like Figure 1-Figure 4 As shown, a high-pressure double homogenization device for producing vegetable protein liquid includes a plunger reciprocating pump system 1, a double homogenization mechanism 2, a base and a housing 3. The material is pressurized by the plunger reciprocating pump system 1 and transported to the double homogenization mechanism 2 for homogenization. The plunger reciprocating pump system 1 and the double homogenization mechanism 2 are installed on the base and the housing 3.

[0021] The plunger reciprocating pump system 1 described in this embodiment includes a material feed port 4 , a plunger and power mechanism 5 , a pump body 6 , a pressure regulating valve group 7 and a material discharge channel 8 .

[0022] In this embodiment, the stirring raw materials are prepared according to the process requirements and mixed according to the mass ratio, including 8.8% sunflower oil, 13.3% pea protein powder, 2% glucose, 0.5% maltodextrin, 0.5% starch and 74% water. The mixed suspension enters the plunger reciprocating pump system 1 from the material feed port 4. At this time, the material liquid is relatively rough. The plunger and power mechanism 5 provide power and make the plunger reciprocate in the pump body 6 to generate high pressure. When the material is transported, it passes through the valve group 7. The gap size of the valve group 7 is adjusted to make the high-pressure material pressure reach 40MPa, and is transported to the double homogenization mechanism 2 through the material discharge channel 8.

[0023] The dual homogenizing mechanism 2 in this embodiment is composed of an impact homogenizing unit 9 and a convection collision homogenizing unit 10. The material flows through the impact homogenizing unit 9 and the convection collision homogenizing unit 10 in sequence to complete the dual homogenization.

[0024] The impact homogenization unit 9 described in this embodiment is composed of an impact homogenization feed channel 11, an impact valve seat 12, a homogenization valve core 13, an impact ring 14, an operating mechanism 15 and a conical pressurization channel 16. The impact homogenization feed channel 11 is connected to the material discharge channel 8, and the material enters the impact homogenization unit 9 from the impact homogenization feed channel 11. The homogenization valve seat 12, the homogenization valve core 13 and the impact ring 14 are installed and fitted. There is a gap between the homogenization valve seat 12 and the homogenization valve core 13, and the size of the gap is adjusted by operating the position of the homogenization valve core 13 by the operating mechanism 15. The material is ejected from the gap at high speed and ejected after being impacted by the impact ring, generating cavitation effect, impact effect and shear effect, thereby improving the degree of dispersion uniformity. The material then enters the conical pressurization channel 16, and the channel diameter changes from large to small, increasing the pressure lost after the material is impacted and homogenized, and the pressure is between 10-20 MPa.

[0025] The convection collision homogenization unit 10 described in this embodiment includes a convection homogenization feed port 17, an interaction cavity 18, and a convection homogenization discharge port 19. The convection homogenization feed port 17 is connected to the conical pressurization channel 16. The pressurized material enters the interaction cavity 18 through the convection homogenization feed port 17. The interaction cavity 18 is provided with a shunt channel 20, an interaction channel 21 and a collision cavity 22. After the material is divided into two directions in the shunt channel 20, it is interacted again by the interaction channel 21, and a strong high-speed collision is performed in the hollow spherical collision cavity 22. The particle collision, cavitation and turbulence in the fluid further increase the homogenization effect and release the pressure. The homogenized material flows out from the convection homogenization discharge port 19. Subsequent processing is then carried out to obtain pea plant protein liquid.
