Description

Technical Field

[0001] This application relates to the field of plant component concentrators, and in particular to an apparatus and process method for concentrating plant components. Background Technology

[0002] Currently, concentration tanks are used for concentrating materials such as traditional Chinese medicine, Western medicine, starch sugar, and dairy products, as well as for recovering industrial organic solvents. They are suitable for low-temperature vacuum concentration of heat-sensitive materials in the pharmaceutical, food, and chemical industries, with small batches and a wide variety of products. The equipment consists of a concentration tank, a vertical tube heater, a condenser, piping valves, and a vacuum system. The concentration tank has a jacketed structure, and the condenser adopts a shell-and-tube design, equipped with a hydraulic ejector or vacuum pump to create a low-pressure environment.

[0003] In the prior art, a concentrator includes: a heater, an evaporation chamber, and a heat exchanger. The heater is hollow inside and has a steam inlet at its bottom. The bottom of the evaporation chamber is connected to the heater via a pipe, the top of the heater is connected to the middle of the evaporation chamber via a pipe, the top of the evaporation chamber is connected to the heat exchanger via a pipe, and the drain outlet of the heat exchanger is connected to a water receiver. During use, steam is generated in the evaporation chamber and then discharged and condensed, thereby enabling concentration.

[0004] Regarding the aforementioned existing technologies, some materials contain saponin-based extracts that are prone to foaming. When spraying to form droplets, bubbles will quickly form. The faster the foam is generated, the larger the volume will be. Therefore, it is very easy for the material to be sprayed out, affecting the concentration effect of the material extraction. Improvements are urgently needed. Summary of the Invention

[0005] In order to reduce the impact of direct discharge of foam material on the concentration of the material and to ensure the concentration effect of the material, this application provides a device and process method for concentrating plant ingredients.

[0006] The technical solution provided in this application for a device and process for concentrating plant components is as follows:

[0007] The device includes an evaporator body, a steam chamber inside the evaporator body, a feed pipe on the side wall of the evaporator body connected to the steam chamber, a nozzle at the end of the feed pipe, a drain pipe at the bottom of the evaporator body, a stirring seat at the top of the evaporator body, a stirring chamber inside the stirring seat connected to the steam chamber, a steam discharge pipe on the stirring seat connected to the stirring chamber, a defoaming wheel plate rotatably connected inside the stirring chamber, the axis of the defoaming wheel plate being aligned with the steam flow direction, and a driving component on the stirring seat for driving the defoaming wheel plate to rotate.

[0008] By adopting the above technical solution, during use, the material enters through the feed pipe and is sprayed by the nozzle, causing the material to evaporate and form steam that flows out through the discharge pipe. After subsequent condensation, the concentration is completed. The use of a rotating defoaming wheel plate can effectively prevent foam and fine droplet entrainment, making it particularly suitable for the evaporation and concentration of easily foaming materials. This allows for better concentration of the material and ensures a better concentration effect.

[0009] Preferably, a rotating rod is rotatably connected to the driving component, and the defoaming wheel plate is fixed on the rotating rod. The defoaming wheel plate is composed of multiple rectangular plates, and the length direction of the rectangular plates is arranged along the steam flow direction. A baffle ring is also provided on the rotating rod, and the baffle ring is located on the side of the defoaming wheel plate close to the driving component.

[0010] By adopting the above technical solution, the rectangular plate with a rectangular shape can better increase the rotation area during use, so that the bubbles can be touched more quickly and conveniently, thereby breaking the foam and facilitating the discharge of steam. In addition, with the baffle ring, the steam carrying the bubbles can flow to the outside of the rectangular plate, so that the foam can be punctured at a position with a faster angular velocity, which can better reduce the number of foams and better ensure the concentration of the material.

[0011] Preferably, the rectangular plate has multiple guide grooves on its sidewall, and the guide grooves are opened along the radial direction of the rotating rod.

[0012] By adopting the above technical solution and opening the flow guide channel, firstly, the weight of the rectangular plate can be reduced, and the smoothness of the rotation of the rotating foam breaking wheel can be improved; secondly, the contact area can be increased, and the airflow can be guided, improving the convenience of foam breaking upon contact; thirdly, the groove edge of the flow guide channel has a stronger foam breaking effect compared to the flat surface; and fourthly, the liquid can be thrown out in an orderly manner, preventing liquid from splashing and flowing into the later stage.

[0013] Preferably, the stirring chamber is provided with a flow guide seat, and the flow guide seat has a flow guide cavity. The flow guide cavity is used to increase the steam flow space and remove residual liquid material. The bottom of the flow guide seat has an outlet for discharging material and an air inlet connected to the flow guide cavity. The steam discharge pipe is connected to the other end of the flow guide cavity.

[0014] By adopting the above technical solution, the flow guide cavity can increase the flow distance of steam, thereby further removing the foam entrained in the steam and ensuring the concentration effect of the material.

[0015] Preferably, there are multiple feed pipes, and the multiple feed pipes are arranged symmetrically.

[0016] By adopting the above technical solution and using a symmetrical arrangement of the feed pipe, the nozzles can spray in opposite directions. By controlling the parameter ratio W within a certain range, large droplets are further collided and broken up, which enhances the evaporation effect. Small droplets collide and merge, which accelerates mass transfer and improves evaporation efficiency.

[0017] Preferably, the rotating rod extends into the steam chamber, a heating cone plate is provided at the bottom of the rotating rod, a heating cone surface is formed on the upper side of the heating cone plate, the inner radial direction of the heating cone surface gradually decreases downward, a drain outlet is provided at the bottom of the heating cone plate, a plurality of heating baffles are provided on the heating cone surface, the heating baffles are arranged radially along the rotating rod, and heating plates are provided on the heating baffles.

[0018] By adopting the above technical solution, during use, the heating element heats the heating baffle, which in turn heats the heating cone. During the discharge of the material, the heating cone provides auxiliary heating, thereby reducing the impact of cooling on the evaporation effect of the material. During the rotation of the heating cone, the liquid can rotate outward under centrifugal force and move towards the center under gravity. Furthermore, the rotation of the heating cone allows the liquid or some of the vapor to come into contact with the heating baffle, which can better heat the material, prevent overheating and sticking to the wall, and supplement the concentration effect.

[0019] Preferably, the heating baffle is inclined in a direction away from the heating cone plate, and the inclination direction of the heating baffle is opposite to the rotation direction of the heating cone plate.

[0020] By adopting the above technical solution, the inclined heating baffle can reduce wind resistance and improve the smoothness of the heating cone plate rotation. On the other hand, the inclined heating baffle can generate upward induction, which can make the steam flow more smoothly into the stirring chamber and improve the smoothness of steam discharge.

[0021] Preferably, the defoaming wheel plate is composed of multiple inclined wind baffles, with adjacent wind baffles staggered, and each wind baffle has air vents of different sizes formed at its upper and lower ends. The wind baffle with the inclination direction opposite to that of the defoaming wheel plate has multiple ventilation holes through it.

[0022] By adopting the above technical solution, during use, the evaporator body is in a vacuum state, with pressure flowing towards the steam discharge pipe. When the steam passes through the baffle, firstly, it can increase the contact area of ​​the baffle plate, better puncturing the foam; secondly, the staggered and inclined baffle can compress the steam, causing it to be discharged from the upper air vent, thus enabling more comprehensive foam puncture; thirdly, the opening of the vent not only reduces the resistance of the foam wheel plate rotation and improves the smoothness of rotation, but also creates a faster airflow when the steam passes through, blowing it onto the adjacent baffle plate. At this time, it will merge with the relatively slower airflow from the air vent, thereby achieving the effect of further removing foam and improving the concentration effect of the material.

[0023] Preferably, an auxiliary wheel is rotatably connected to the rotating rod, and the auxiliary wheel is composed of multiple inclined rotating wheel plates.

[0024] By adopting the above technical solution, during use, when the defoaming wheel plate rotates, the gas can blow the auxiliary wheel to rotate after passing through the vent. The rotation speed of the auxiliary wheel is different from that of the defoaming wheel plate, so that the structures with different rotation speeds can puncture the foam. The space for gas flow is not fixed, which can better improve the steam discharge effect.

[0025] Preferably, a rotating guide wheel is rotatably connected to the upper side wall of the steam chamber. The rotating guide wheel includes a rotating wall rotatably connected to the steam chamber. Multiple rotating guide plates are arranged at intervals along the circumference on the rotating wall. The tilting direction of the rotating guide plates is the same as the rotation direction of the defoaming wheel plate.

[0026] By adopting the above technical solution, and using a tilted rotating guide plate, the steam can flow more smoothly. During the flow, the rotating guide wheel can be driven to rotate, which can better break the foam in the steam on the side wall of the steam chamber, reduce the amount of foam in the later stage, and improve the steam concentration effect.

[0027] A process for concentrating plant components, the specific steps are as follows: the size of the foam defoaming wheel plate (4) is 0.5-2cm away from the cylinder wall, and the angle of the guide groove (15) is -10 to -30°.

[0028] Number of blades on the defoaming wheel plate (4): 3-4;

[0029] Nozzle orientation: Vertical to the inner wall of the evaporator body (6), with two layers of nozzles, one above the other, facing each other in pairs, four in the upper layer and four in the lower layer, forming a 45° angle between the upper and lower nozzles;

[0030] Nozzle divergence angle: 81~84°;

[0031] Nozzle relative spacing: 0.8~1.0m;

[0032] Evaporator body (6) internal vacuum degree: greater than 0.075, rotation speed: 1000-3000rpm.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. During use, the material enters through the feed pipe and is sprayed through the nozzle. The vapor evaporates and flows out through the discharge pipe. After subsequent condensation, the concentration is completed. The rotating defoaming wheel can break the foam multiple times, effectively preventing foam and fine droplet entrainment. It is especially suitable for the evaporation and concentration of easily foaming materials, thus achieving better concentration and ensuring the concentration effect of the material.

[0035] 2. During use, the rectangular plate can better increase the rotation area, allowing bubbles to be touched more quickly and conveniently, thus breaking the foam and facilitating the discharge of steam. In addition, with the baffle ring, steam can flow to the outside of the rectangular plate, allowing the foam to be punctured at a faster angular velocity, effectively reducing the amount of foam and better ensuring the concentration of the material.

[0036] 3. The design of the flow channel serves several purposes: first, it reduces the weight of the rectangular plate and improves the smoothness of the rotating foam breaker; second, it increases the contact area and guides the airflow, improving the ease of foam breaking upon contact; and third, it allows the liquid to be ejected more easily, improving the convenience of liquid collection.

[0037] 4. By using a through-jet spray and controlling the parameter ratio W within a certain range, large droplets are further collided and broken up, which enhances the steam effect. Small droplets collide and merge, which accelerates mass transfer and improves evaporation efficiency. Attached Figure Description
