Description

Technical Field

[0001] This utility model relates to the technical field of casein processing equipment, and more specifically, to a vacuum evaporation device for casein concentration. Background Technology

[0002] Casein is a protein extracted from dairy products such as milk, and it has wide applications in the food, pharmaceutical, and chemical industries. Concentration is a crucial step in casein production; its purpose is to remove water from the solution and increase the concentration of casein for subsequent processing.

[0003] Currently, existing vacuum evaporation devices for casein concentration have flaws in their design regarding the location of the material inlet and outlet. For example, some devices place the inlet at the top and the outlet at the bottom, which may result in the material having an excessively short or long residence time in the evaporation chamber. When the residence time is too short, the casein solution is not sufficiently concentrated and cannot reach the expected concentration, affecting the quality of subsequent processing; while when the residence time is too long, it will exacerbate scaling inside the equipment, and the heat-sensitive components in casein are easily destroyed, reducing the quality of casein. In view of this, we propose a vacuum evaporation device for casein concentration. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a vacuum evaporation device for casein concentration. This addresses the technical problem that the current device's inlet and outlet are located on the upper and lower sides, which easily leads to unstable residence time of materials in the evaporation chamber, exacerbating scaling inside the equipment and affecting the quality of casein.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vacuum evaporation device for casein concentration, comprising a vacuum evaporation device body, wherein a heating component is fixedly installed inside the vacuum evaporation device body, and a connecting pipe for connecting to an external heating mechanism is fixedly installed on the top of the heating component.

[0006] The heating assembly includes a heating plate with a conical guide surface at the top. The heating plate has a heating chamber connected to a connecting pipe inside. A spiral guide plate is fixedly installed at the top of the guide surface, and the center of the spiral guide plate is aligned with the feeding port of the vacuum evaporation device body. A feeding port for discharging material is opened on the side wall of the heating plate at the end of the spiral guide plate. A feeding pipe penetrating the bottom of the heating plate is fixedly installed inside the feeding port.

[0007] This invention, by incorporating a spiral guide plate and a downwardly inclined flow surface, allows the casein solution entering from the feed port to flow along a spiral path on the flow surface of the heating plate. This significantly extends the residence time of the material in the heating zone, avoiding insufficient concentration caused by an excessively short path. Simultaneously, the spiral guide structure ensures a relatively uniform material flow velocity, reducing the possibility of excessively long local residence times and thus lowering the probability of damage to heat-sensitive components. This design guarantees the consistency of the casein solution evaporation time, ensuring the quality of the casein.

[0008] Preferably, the corners where the spiral guide plate connects to the flow guide surface are constructed with guide arc surfaces, and the sides of the spiral guide plate adjacent to the flow guide surface are all smooth surfaces.

[0009] Preferably, the bottom side of the spiral guide plate extends upward to form a connecting groove, and the side of the guide surface that is combined with the spiral guide plate has a plurality of connecting holes that are connected to the connecting groove.

[0010] Preferably, a baffle plate is fixedly installed on the top side of the heating plate located at the feeding pipe position and is fixedly connected to the spiral guide plate, and the shape of the baffle plate is consistent with the shape of the pipe wall of the feeding pipe.

[0011] Preferably, a rotating seat is fixedly provided on the inner side of the heating cavity, and a spiral blade is rotatably installed at the center of the rotating seat.

[0012] Preferably, the top of the heating plate is fixedly provided with a plurality of connecting sleeves communicating with the heating chamber, and the connecting sleeves are connected to the connecting pipe by threads.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This invention, by setting a spiral guide plate and a downwardly inclined guide surface, allows the casein solution entering from the feeding port to flow along a spiral path on the guide surface of the heating plate, significantly extending the residence time of the material in the heating zone and avoiding the problem of insufficient concentration caused by an excessively short path. Simultaneously, the spiral guide structure ensures a relatively uniform material flow speed, reducing the possibility of excessively long local residence times, thereby lowering the probability of damage to heat-sensitive components. This design guarantees the consistency of the casein solution evaporation time, ensuring the quality of the casein.

[0015] 2. This invention also utilizes the heating chamber inside the heating plate to continuously provide heat. Combined with the guidance of the spiral guide plate, this ensures that the material makes full contact with the guiding surface of the heating plate during flow, resulting in more uniform heating. Furthermore, the guide arc surface and smooth side design at the connection between the spiral guide plate and the guiding surface reduce resistance to material flow, minimizing the possibility of localized material accumulation. This reduces scaling inside the equipment, extending its service life and maintaining stable operation. Attached Figure Description

[0022] like Figures 1 to 5 As shown, the present invention relates to a vacuum evaporation device for casein concentration, comprising a vacuum evaporation device body 1, a heating component 2 fixedly installed inside the vacuum evaporation device body 1, and a connecting pipe 6 for connecting to an external heating mechanism fixedly installed on the top of the heating component 2; the external heating mechanism supplies heat to the heating plate 3 through the connecting pipe 6, thereby increasing the temperature of the heating component 2, so that the material can be heated and evaporated when flowing on the heating component 2.

[0023] The heating assembly 2 includes a heating plate 3. The top of the heating plate 3 has a conical guide surface 301. The interior of the heating plate 3 has a heating chamber 302 that communicates with the connecting pipe 6. A spiral guide plate 4 is fixedly installed on the top of the guide surface 301, and the center of the spiral guide plate 4 is aligned with the feeding port of the vacuum evaporation device body 1. A feeding port 303 for feeding is opened on the side wall of the heating plate 3 at the end of the spiral guide plate 4. A feeding pipe 5 that penetrates the bottom of the heating plate 3 is fixedly installed inside the feeding port 303. The design of the guide surface 301 can form a downward sloping surface. Combined with the design of the spiral guide plate 4, the flow direction of the material can be controlled, so that the material can maintain a uniform flow and maintain the stability of the heating time. The design of the feeding pipe 5 facilitates the outflow of the evaporated material, thereby maintaining the consistency of the material heating time and reducing the impact of unstable contact time on the material evaporation quality.

[0024] In the embodiments of this utility model, the corner of the connection between the spiral guide plate 4 and the flow guide surface 301 is constructed with a guide arc surface 402, and the adjacent sides of the spiral guide plate 4 and the flow guide surface 301 are all smooth surfaces; the design of the guide arc surface 402 can improve the smoothness of the connection, reduce the material flow resistance, reduce dead corner problems, effectively prevent material accumulation, improve the stability of material flow, and reduce the occurrence of scaling.

[0025] In an embodiment of this utility model, a connecting groove 401 is provided on the bottom side of the spiral guide plate 4, and a plurality of connecting holes 305 connected to the connecting groove 401 are provided on the side where the flow guiding surface 301 is combined with the spiral guide plate 4. The design of the connecting groove 401 and the connecting holes 305 can further improve the heating effect of the spiral guide plate 4, so that the temperature of the spiral guide plate 4 and the heating plate 3 can be kept consistent, and the heating range of the material can be increased.

[0026] In an embodiment of this utility model, a baffle plate 304 is fixedly installed on the top side of the heating plate 3 located at the feeding pipe 5 and is fixedly connected to the spiral guide plate 4. The shape of the baffle plate 304 is consistent with the shape of the pipe wall of the feeding pipe 5. The design of the baffle plate 304 can restrict the flow position of the material, so that the evaporated material can flow stably into the interior of the feeding pipe 5.

[0027] In an embodiment of this utility model, a rotating seat 307 is fixedly provided on the inner side of the heating cavity 302, and a spiral blade 7 is rotatably installed at the center of the rotating seat 307. The design of the spiral blade 7 can promote the flow of heat source in the heating cavity 302 during the heat source delivery process, so that the heating plate 3 is heated more evenly, and further ensures the stability and consistency of heating the raw materials.

[0028] In an embodiment of this utility model, a plurality of connecting sleeves 306 communicating with the heating chamber 302 are fixedly provided on the top of the heating plate 3, and the connecting sleeves 306 and the connecting pipe 6 are connected by threads; the fitting facilitates assembly and installation.

[0029] Working Principle: This embodiment provides a vacuum evaporation device for casein concentration. During operation, an external heating mechanism supplies heat to the heating chamber 302 inside the heating plate 3 via a connecting pipe 6, raising the temperature of the heating plate 3 and the connected spiral guide plate 4. Casein raw material is added through the feeding port of the main body 1 of the vacuum evaporation device. Because the center of the spiral guide plate 4 is aligned with the feeding port, the raw material falls into the central area of ​​the spiral guide plate 4. Guided by the spiral guide plate 4, the raw material flows along a spiral path on the conical guide surface 301 at the top of the heating plate 3. During the flow, the heating plate 3 remains at a high temperature due to the heat source in the heating chamber 302. The raw material contacts the guide surface 301 and the spiral guide plate 4 of the heating plate 3 and is heated, causing water to evaporate. Simultaneously, the vacuum environment inside the main body 1 of the vacuum evaporation device lowers the boiling point of water, accelerating water evaporation and achieving raw material concentration. The guide arc surface 402 at the connection between the spiral guide plate 4 and the guide surface 301, as well as their adjacent smooth sides, reduce the resistance to raw material flow, allowing for smooth flow. Furthermore, the connecting groove 401 on the bottom side of the spiral guide plate 4 is connected to the connecting hole 305 on the guide surface 301, which can expand the heating range, increase the contact area between the raw material and the heating component, and improve the heating efficiency. When the raw material flows to the end of the spiral guide plate 4, under the action of the baffle plate 304, it accurately enters the discharge port 303 on the side wall of the heating plate 3, and flows through the discharge pipe 5 to the subsequent processing area in the main body 1 of the vacuum evaporation device, completing the initial heating, concentration and conveying process. In addition, the spiral blade 7 rotatably installed on the rotating seat 307 inside the heating chamber 302 can promote the flow of heat source in the heating chamber 302 during the heat source conveying process, making the heating plate 3 more uniformly heated, and further ensuring the stability and consistency of the heating of the raw material.
