Abstract
Description
Technical Field
[0001] This utility model belongs to the field of star anise processing technology, specifically relating to an ultrasonic tunnel-type blanching machine for star anise. Background Technology
[0002] Star anise is a well-known spice and also has medicinal uses. Its peel, seeds, and leaves all contain aromatic oils and are important raw materials for the manufacture of cosmetics, sweet wines, beer, and the food industry. After being harvested, star anise leaves must be processed promptly to avoid reducing their quality. The first step is processing: before processing, the fruit and leaves should be spread out and not piled up to avoid rain and moisture, which can cause them to heat up and mold. Therefore, generally, harvested star anise needs to be dried. The current method of blanching involves placing fresh star anise in an uncovered pot filled with boiling water and stirring with a wooden stick for 10 minutes. When the fruit color changes from green to light yellow, it is removed and spread out to dry on a drying ground or straw mats for 4-5 days to become the finished product.
[0003] A search revealed that Chinese invention patent application CN114431446A discloses a blanching device for processing star anise fruit, comprising a blanching mechanism, a feeding conveyor belt on one side of the blanching mechanism, a conveyor belt support fixedly connected to the lower side of the feeding conveyor belt, a drying mechanism on the side of the blanching mechanism away from the feeding conveyor belt, and a discharge mechanism on the side of the drying mechanism away from the blanching mechanism.
[0004] Regarding the aforementioned technologies, in the process of blanching star anise, ultrasonic high-temperature blanching is not ideal, and stains are easily left on the star anise after blanching, resulting in insufficient blanching performance. Therefore, it is urgent to design an ultrasonic tunnel blanching machine for star anise to address these issues. Utility Model Content

[0028] In this embodiment: the blanching execution mechanism 3 includes a trapezoidal box 301 horizontally fixed inside the auxiliary mechanism 2. A connecting plate 302 is vertically fixed inside the trapezoidal box 301. A waterproof ultrasonic device 303 is fixedly installed on the connecting plate 302. A temperature testing component is fixedly installed on the connecting plate 302. A first rotating shaft 305 is longitudinally and rotatably installed inside the trapezoidal box 301. A conveyor belt 307 is rotatably installed on the outer surface of the first rotating shaft 305. A discharge component 312 is rotatably installed on one side of the conveyor belt 307. The discharge component 312 includes a second rotating shaft disposed on one side of the conveyor belt 307. A discharge belt is rotatably installed on the outer surface of the second rotating shaft. A discharge plate is fixedly installed on the discharge belt at equal intervals. A power assembly is fixedly installed between the first rotating shaft 305 and the discharge assembly 312. A vertical frame 308 is fixedly installed longitudinally and parallel to each other on the conveyor belt 307. A rotating rod 309 is rotatably mounted longitudinally inside the vertical frame 308. A free-rotating roller 3091 is fixedly installed on the outer surface of the rotating rod 309. A heating plate 310 is fixedly installed below the conveyor belt 307. A second heater 311 is fixedly installed on the heating plate 310. Water 313 is filled inside the trapezoidal box 301. The temperature testing assembly includes a temperature sensor 304 mounted on the connecting plate 302, and a temperature controller 3041 is fixedly installed on the temperature sensor 304. The power assembly includes a belt 3061 located between the first rotating shaft 305 and the discharge assembly 312. A tensioning pulley 3051 is rotatably mounted inside the belt 3061. A power motor 306 is fixedly installed at one end of the first rotating shaft 305. The waterproof ultrasonic sensor 303 typically employs a special polymer material encapsulation, commonly known as a micro-waterproof membrane, and a sealed design to ensure stable operation of the sensor in harsh, humid, and watery environments. The core principle of ultrasonic waterproofing lies in its high-frequency vibrations altering the microstructure of the material surface, making it difficult for water molecules to adhere and penetrate. The temperature sensor 304 is a device used to measure temperature; it has a probe installed and extends into the water body 313. The temperature controller 3041's main function is to detect temperature; it can automatically control the heating equipment's on / off state based on temperature changes to achieve the desired temperature. The temperature sensor 304, temperature controller 3041, and waterproof ultrasonic sensor 303 are all existing technologies and are electrically connected to an external control circuit.
[0029] Working principle: In use, the water 313 in the trapezoidal box 301 is first heated by the second heater 311 to the heating plate 310, and the water temperature is controlled by the temperature sensor 304 and the temperature controller 3041. At the same time, the waterproof ultrasonic device 303 is activated to vibrate the water 313 with ultrasonic high frequency. The operator puts the star anise to be blanched into the heated water 313 in the trapezoidal box 301 through the feeding plate 204. The power motor 306 is started to drive the first rotating shaft 305 to rotate. At the same time, the belt 3061 and the tension wheel 3051 rotate, causing the discharge component 312 to rotate. The water level is maintained at approximately the position of the upper rotating rod 309 axis, thus causing part of the free-spinning roller 3091 to rotate. Part of the star anise is submerged in the water, while the other part is above the water surface. When the conveyor belt 307 moves, the free-rotating roller 3091 rotates due to the resistance of the water. The free-rotating roller 3091 agitates the star anise, improving the blanching effect. The steam generated inside the tunnel box 201 is extracted through the heat absorption hood 205. The blanched star anise is carried out through the rotating discharge assembly 312 and falls into the receiving box 208. At the same time, the drying fan 206 and the first heater 207 are turned on to dry the blanched star anise in the receiving box 208. During drying, the stirring roller assembly 209 is turned on to make the blanched star anise rotate and dry evenly. Finally, the star anise is moved out of the tunnel box 201 through the concave groove 210 by the I-beam 2101 to complete the blanching process.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
