Description

Technical Field

[0001] This utility model relates to the field of blanching devices, and in particular to a rapid blanching device for aloe vera based on electromagnetic induction heating. Background Technology

[0002] Aloe vera, as a multifunctional plant, contains abundant nutrients and bioactive substances in its leaves. However, during processing, if not properly handled in a timely manner, these valuable components may be destroyed by enzymatic reactions, leading to problems such as browning and nutrient loss in aloe vera products. Blanching uses high temperatures to quickly destroy the enzyme activity within aloe vera cells, especially those enzymes that can trigger browning, thus preventing undesirable color changes during subsequent processing or storage. Rapid heating preserves vitamins, minerals, and other bioactive components in aloe vera, avoiding nutrient loss caused by prolonged exposure to air.

[0003] Chinese Patent CN217089417U discloses an energy-saving electromagnetic drum blanching machine. The machine preheats and keeps the air flowing through the drum by driving the air intake mechanism into the drum through the first coil and the air intake hole. However, when blanching aloe vera, there is a problem of uneven heating caused by the stacking of aloe vera. In view of this, a rapid blanching device for aloe vera based on electromagnetic induction heating is provided. Utility Model Content

[0004] The main purpose of this invention is to provide a rapid aloe vera blanching device based on electromagnetic induction heating, so as to solve the problem of uneven heating caused by the stacking of aloe vera when blanching aloe vera, as mentioned in related technologies.

[0005] To achieve the above objectives, according to one aspect of this utility model, a rapid aloe vera blanching device based on electromagnetic induction heating is provided, comprising a base, a heating cylinder fixedly installed at the upper end of the base, a rotating groove extending through the side wall of the heating cylinder, a heating coil mounting groove being provided at the arc wall of the rotating groove, and a heating coil being fixedly installed in the heating coil mounting groove, and further comprising: a blanching cylinder, a blanching groove extending through the side wall of the blanching cylinder, and a conveying blade fixedly installed at the arc wall of the blanching groove, wherein the conveying blade drives the aloe vera in the blanching groove to tumble to ensure that each side of the aloe vera is heated evenly.

[0006] Furthermore, the blanching cylinder is a conical structure with an increasing radius from the feed end to the discharge end.

[0007] Furthermore, the radius of the inner wall of the blanching trough increases from the feed end to the discharge end.

[0008] Furthermore, the conveying blade has a spiral structure.

[0009] Furthermore, the edges of the conveying blades are rounded, and the spiral radius of the conveying blades increases from the feed end to the discharge end of the blanching trough.

[0010] Furthermore, the arc wall of the blanching cylinder is provided with several connecting holes that connect to the blanching groove.

[0011] Furthermore, the heating coil has a spiral structure, and the spiral radius of the heating coil increases from the feed end to the discharge end of the blanching cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, aloe vera is placed into the blanching trough from the feed end of the blanching cylinder. A heating coil heats the side wall of the blanching cylinder to heat the aloe vera in the trough. The blanching cylinder rotates, and during rotation, conveyor blades push the aloe vera leaves to tumble, preventing them from piling up and ensuring even heating on all sides. This reduces the movement speed of the aloe vera and extends the heating time. The edges of the conveyor blades are rounded to prevent damage to the aloe vera leaves. The radius of the blanching trough increases from the feed end to the discharge end. The aloe vera leaves enter from the small-diameter end of the blanching cylinder and, initially, are rapidly heated to the blanching temperature due to the concentrated high-frequency magnetic field of the heating coil. As the radius of the blanching tank expands, the magnetic field strength gradually decreases, and the aloe vera enters the heat preservation stage to avoid overheating and damaging heat-sensitive components. The conical structure of the blanching tank reduces the frictional resistance between the aloe vera and the side wall of the blanching tank, guiding the aloe vera leaves to move towards the discharge port and preventing the aloe vera leaves from piling up and causing blockage. The connecting hole extends the vortex heating area from the surface of the blanching cylinder to the inside, making the aloe vera leaves more directly heated and increasing the heating rate. At the same time, the high-temperature air in the heating coil installation slot penetrates the inner wall of the blanching cylinder, forming forced convection heat transfer, allowing the hot air to come into direct contact with the aloe vera leaves and improving the uniformity of temperature distribution.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] This embodiment provides a rapid aloe vera blanching device based on electromagnetic induction heating, including a base 1, a heating cylinder 2 fixedly installed on the upper end of the base 1, a rotating groove 21 penetrating through the side wall of the heating cylinder 2, a heating coil mounting groove 22 being opened at the arc wall of the rotating groove 21, and a heating coil 221 being fixedly installed in the heating coil mounting groove 22. It also includes a blanching cylinder 3, a blanching groove 31 penetrating through the side wall of the blanching cylinder 3, and a conveying blade 32 being fixedly installed at the arc wall of the blanching groove 31. The conveying blade 32 drives the aloe vera in the blanching groove 31 to roll to ensure that each side of the aloe vera is heated evenly.

[0027] like Figure 3 , Figure 5 As shown, the blanching cylinder 3 is a conical structure with the radius increasing from the feed end to the discharge end;

[0028] like Figure 6 As shown, the inner radius of the blanching trough 31 increases from the feed end to the discharge end. The aloe vera leaves enter from the small diameter end of the blanching cylinder 3. In the initial stage, they are rapidly heated to the blanching temperature by the concentrated effect of the high-frequency magnetic field of the heating coil 221. As the radius of the blanching trough 31 expands, the magnetic field strength gradually decreases, and the aloe vera enters the heat preservation stage to avoid overheating and damage to heat-sensitive components. The conical structure of the blanching trough 31 reduces the frictional resistance between the aloe vera and the side wall of the blanching trough 31, guiding the aloe vera leaves to move towards the discharge port and preventing the aloe vera leaves from piling up and causing blockage.

[0029] like Figure 4 , Figure 6 As shown, the conveying blade 32 has a spiral structure;

[0030] like Figure 4 , Figure 6As shown, the conveying blade 32 has rounded corners at its edges. The spiral radius of the conveying blade 32 increases from the feed end to the discharge end of the blanching trough 31. The rounded corners at the edges of the conveying blade 32 prevent damage to the aloe vera leaves. When rotating, the conveying blade 32 pushes the aloe vera leaves to roll, preventing them from stacking and ensuring that each side is heated evenly. The heating time is extended by reducing the moving speed of the aloe vera.

[0031] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the arc wall of the blanching cylinder 3 is provided with several connecting holes 33 that connect to the blanching groove 31. The connecting holes 33 extend the vortex heating area from the surface of the blanching cylinder 3 to the interior, so that the aloe vera leaves are heated more directly and the heating speed is increased. At the same time, the high temperature air in the heating coil mounting groove 22 penetrates the inner wall of the blanching cylinder 3 to form forced convection heat transfer, so that the hot air comes into direct contact with the aloe vera leaves and improves the uniformity of temperature distribution.

[0032] like Figure 3 , Figure 7 As shown, the heating coil 221 has a spiral structure. The spiral radius of the heating coil 221 increases from the feed end to the discharge end of the blanching cylinder 3. When the aloe vera leaf is located at the small diameter end of the blanching trough 31, it is rapidly heated to the blanching temperature by the concentrated effect of the high-frequency magnetic field of the heating coil 221. As the heating coil 221 is used, the magnetic field strength gradually decreases and the aloe vera enters the heat preservation stage to avoid overheating and damage to the heat-sensitive components.

[0033] In practical use, aloe vera is placed into the blanching trough 31 from the feed end of the blanching cylinder 3. The side wall of the blanching cylinder 3 is heated by the heating coil 221 to heat the aloe vera in the blanching trough 31. The blanching cylinder 3 rotates, causing the conveying blades 32 inside the cylinder 3 to rotate as well. During rotation, the conveying blades 32 push the aloe vera leaves to tumble, preventing them from piling up and ensuring that each side is heated evenly. By reducing the moving speed of the aloe vera, the heating time is extended. The edges of the conveying blades 32 are rounded to avoid damaging the aloe vera leaves. The radius of the blanching trough 31 increases from the feed end to the discharge end. The aloe vera leaves enter from the small-diameter end of the blanching cylinder 3 and are initially heated by the high temperature of the heating coil 221. The concentrated magnetic field rapidly raises the temperature to the blanching temperature. As the radius of the blanching tank 31 expands, the magnetic field strength gradually decreases, and the aloe vera enters the heat preservation stage to avoid overheating and damaging heat-sensitive components. The conical structure of the blanching tank 31 reduces the frictional resistance between the aloe vera and the side wall of the blanching tank 31, guiding the aloe vera leaves towards the discharge port and preventing the aloe vera leaves from piling up and causing blockage. The connecting hole 33 extends the eddy current heating area from the surface of the blanching cylinder 3 to the interior, allowing the aloe vera leaves to be heated more directly and increasing the heating rate. At the same time, the high-temperature air in the heating coil mounting slot 22 penetrates the inner wall of the blanching cylinder 3, forming forced convection heat transfer, allowing the hot air to come into direct contact with the aloe vera leaves and improving the uniformity of temperature distribution.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
