Description

Technical Field

[0001] This utility model relates to the technical field of Panax notoginseng root processing equipment, and in particular to a Panax notoginseng root cleaning device. Background Technology

[0002] The roots of Panax notoginseng are an important component of the plant, rich in various active ingredients beneficial to the human body and possessing extremely high medicinal value. Due to their slender and complex structure, these roots often accumulate a large amount of soil and impurities during harvesting, making cleaning an indispensable step in processing. Currently, traditional cleaning methods primarily employ water washing; however, this method has significant drawbacks: firstly, prolonged soaking leads to the hydrolysis of saponins, a key active ingredient in Panax notoginseng, resulting in a substantial loss of effective components; secondly, the high-pressure water rinsing used to remove stubborn impurities can easily cause the roots to break, affecting the integrity and quality of the medicinal material; and finally, the high-temperature drying process after cleaning may cause secondary heat damage to the roots, further reducing their efficacy. Therefore, there is an urgent need to provide a Panax notoginseng root cleaning device that is structurally sound, operates gently, and provides effective cleaning, overcoming the problems of incomplete cleaning, damage to the medicinal material's structure, and loss of effective components in existing technologies, thereby improving the overall quality and market competitiveness of Panax notoginseng.

[0049] As a preferred technical solution in this embodiment, a constant temperature heater (not shown in the figure, the constant temperature heater can be a PTC heater) is provided inside the flow guide hood 403 to control the airflow temperature, improve the dehydration efficiency, avoid damage to the roots due to excessive temperature during the cleaning process, and reduce the energy consumption of the subsequent drying process to a certain extent.

[0050] Example 2

[0051] As attached Figure 10 As shown, a Panax notoginseng root cleaning device is provided, wherein the frame 101 is provided with a protective cover 111 covering the silicone brush roller 202; effectively preventing mud and water from splashing during the cleaning process, improving operational safety and environmental hygiene. The rest is basically the same as in Embodiment 1.

[0052] During operation, Panax notoginseng roots with a moisture content of approximately 40% are first evenly fed into the feed end of the mesh belt conveyor 1. Continuous cleaning is achieved by controlling the conveying speed of the mesh belt conveyor 1. In the initial stage, the material passes through the brushing component 2, which is equipped with multiple silicone brush rollers 202 rotating at 20-50 rpm. These brush rollers can effectively remove large pieces of soil from the surface of the roots without damaging the root structure. This process takes about 2 minutes. Next, the material enters the negative pressure cleaning component 3. Through a high negative pressure environment of 0.8 MPa and in conjunction with the perforated plate 303, the fine soil and dust remaining on the surface of the roots are effectively peeled off and collected, preventing impurities from being mixed into subsequent processes. This step takes about 3 minutes. Finally, the material reaches the airflow cleaning component 4, where a high-speed airflow at a constant temperature (not exceeding 40℃) is used for deep cleaning (5% food-grade ethanol atomized particles can be added for disinfection), further cleaning the roots. This process also takes about 3 minutes. Throughout the cleaning process, the temperature was strictly controlled below 40℃, and the total cleaning time was ensured to not exceed 10 minutes to avoid loss of active ingredients due to high temperature or prolonged treatment. The final output Panax notoginseng rootlets had a moisture content reduced to 15%, achieving the goal of efficient and low-damage cleaning. It was verified that its saponin retention rate was ≥85%, which is significantly better than traditional cleaning methods, demonstrating good technological advantages and technical promotion value.
