Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural product processing equipment, and specifically to an automated equipment and control method for withering star anise based on layered temperature control, steam circulation and intelligent linkage. In order to overcome the shortcomings and deficiencies in the prior art, the present equipment is an inventive technology for withering star anise. It is characterized by having a mesh conveyor belt, a fuselage, an ultrasonic atomizer, and an infrared thermal sensor. The fuselage is a closed space with a feed port and a discharge port, and an infrared thermal sensor and an ultrasonic atomizer are placed inside the fuselage. The ultrasonic atomizer controls the humidity in the body to ensure that the humidity in the body can be maintained in the optimal humidity range for withering star anise. The infrared thermal sensor can provide real-time feedback on the body temperature and control the temperature within the optimal star anise withering range. The ultrasonic atomizer of the present invention has the outstanding advantages of simple operation, convenient temperature and humidity control, and fully automatic withering of star anise with high efficiency. Background Art
[0002] This technology is mainly used in the processing technology of traditional agricultural products, star anise. Star anise is an important spice and Chinese medicinal material. After picking, star anise needs to go through a series of processes, among which the greening process is a very important one. The existing greening equipment has three major technical defects:
[0003] 1. Single-layer infrared heating leads to uneven temperature field (the upper layer is burnt and the lower layer is undercooked, and the infrared radiation attenuation rate is greater than 40%)
[0004] 2. Steam retention causes increased energy consumption (traditional equipment dehumidification energy consumption accounts for more than 35%)
[0005] 3. Delayed response to manual control (temperature and humidity fluctuations up to ±15°C)
[0006] The continuous fixing machine disclosed in the comparative document CN201510XXXXXX still relies on a single heat source and does not solve the problem of stratified temperature control.
[0007] A layered temperature-controlled steam-coordinated intelligent star anise fixing equipment is now invented, which combines the use of layered temperature control + steam coordination + intelligent linkage joint design to solve the measures taken to solve the defects of the existing technology and the shortcomings that still exist.
[0008] Invention patent content
[0009] (1) Technical issues to be resolved
[0010] The problem that the patent of this invention aims to solve is that the uneven temperature during the star anise withering process in traditional technology causes the upper layer to be burnt (weak infrared penetration) and the lower layer to be half-cooked (relying on heat conduction); the uncontrolled humidity causes water vapor to be retained, resulting in high energy consumption and dull color; the waste of energy leads to low efficiency of pure infrared heating and high investment cost of heat pump.
[0011] (2) Technical solution
[0012] The object of this invention patent is to provide a hierarchical temperature-controlled steam collaborative intelligent star anise killing-green equipment. This equipment has a conveyor belt, a main body, an ultrasonic atomizer, and an infrared thermal sensor. The main body is an enclosed area with a feeding port and a discharging port. The conveyor belt feeds the fruit material into the main body from the feeding port. In the main body, through hierarchical independent heating, each layer has independent infrared + hot air, accurately matching the temperature (the first layer: 105 ± 2 °C; the second layer: 80 ± 2 °C; the third layer: 60 ± 2 °C). When the temperature is too high, the infrared thermal sensor feeds back to control the hot air circulation to reduce the temperature, and when the temperature is too low, the temperature is increased.
[0013] It is conveyed to the third layer through the conveyor belt in the three-layer machine body. The ultrasonic atomizer is used to create a steam circulation for reuse, controlling the humidity (85%) in the machine body to be stable. The third layer is sprayed with water for atomization, and the steam rises to assist the upper layer in killing the green. Through real-time dynamic intelligent regulation of temperature and humidity, mesh belt speed, and water spraying, full-automatic linkage is achieved. This invention patent is completed by combining hierarchical temperature control, steam collaboration, and intelligent linkage design technologies.
[0014] Three independent temperature zone modules in the system architecture:
[0015] Upper high-temperature zone (105 ± 2 °C): Short-wave infrared array (2000 W / m 2 ) + stainless steel parabolic reflector (radiation efficiency increased by 30%)
[0016] Middle balance zone (80 ± 2 °C): Medium-wave infrared (500 W / m 2 ) + steam diversion system (humidity compensation amount 0.1 L / m 3 ·min)
[0017] Lower pretreatment zone (60 ± 2 °C): Atomizing spray module (50 μm droplets) + low-speed hot air (1 m / s)
[0018] Steam dynamic coupling technology in the innovative method:
[0019] Ultrasonic atomization in the third layer (3 seconds / time) → steam rises to the second layer through the diversion plate → the exhaust fan starts with a 5-second delay (wind speed 4 m / s)
[0020] Intelligent linkage algorithm:
[0021] Dual closed-loop PID control: The outer loop compares the set / actual temperature difference, and the inner loop adjusts the infrared power and the opening degree of the hot air valve (response time < 0.5 s)
[0022] In the above technical scheme, the patent of this invention provides a layered temperature-controlled steam-coordinated intelligent star anise fixing equipment, which has the following beneficial effects: rapid enzyme inactivation (polyphenol oxidase inactivation), balanced dehydration and color retention, slow dehydration to prevent brittle cracking, and quality improvement: fixing uniformity > 93%, color compliance rate: L* value ≥ 75, a* value ≤ -10 (yellowish brown), achieving the effect of reducing energy consumption by 20% and increasing production capacity by 50%.

It includes ① a feed inlet, ② a leveler, ③ a mesh conveyor belt, ④ an infrared thermal sensor, ⑤ an ultrasonic atomizer, ⑥ a discharge port, and ⑦ a closed chassis. During operation, the ④ infrared thermal sensor and ⑤ ultrasonic atomizer are pre-activated to ensure the temperature and humidity inside chassis ⑦ meet the star anise fixation criteria. Once these preparations are complete, fresh fruit is poured into the feed inlet ①. The leveler ② spreads the fruit onto the mesh conveyor belt ③ at the feed inlet (to ensure full reaction). The fruit is then conveyed along the mesh conveyor belt ③ into chassis ⑦, where it continues to be transported in the direction indicated by the arrows. During transport, the ④ infrared thermal sensor and ⑤ ultrasonic atomizer monitor the internal temperature and humidity of the chassis in real time, automatically adjusting them based on actual conditions to maintain the optimal temperature and humidity range. Finally, the cured fruit is delivered to the discharge port ⑥, completing the star anise fixation process.
