Complete Solution for the Extraction and Concentration of Polygonatum Extract\u2014From \u201cThe Immortals\u201d Leftover Food\u201d to High-Value-Added Products<\/span><\/strong><\/p>\n

I. Market Value and Manufacturing Challenges of Polygonatum Extract<\/span><\/strong><\/p>\n

Huangjing was among the first varieties included in the \u201cMedicinal and Edible Dual-Use\u201d catalog; it is hailed as \u201cthe immortals\u201d leftover grain\u201c and is known for its ability to tonify qi, nourish yin, strengthen the spleen, and moisten the lungs. In 2026, the \u201dXiang Huangjing\u201c market experienced explosive growth, with the total output value of Anhua Huangjing exceeding 7 billion yuan. As a value-added product, Huangjing paste commands a significantly higher value than fresh Huangjing raw materials and serves as a key category driving the industry\u2019s transition from \u201dselling raw materials\u201d to \u201cselling finished products.\u201d<\/span><\/p>\n

However, the extraction and concentration of Polygonatum extract present three major technical challenges:<\/span><\/p>\n

\n\n\n\n\n\n\n\n
Material Properties<\/span><\/th>\nTechnical Challenges<\/span><\/th>\nEquipment Requirements<\/span><\/th>\n<\/tr>\n<\/thead>\n
High polysaccharide content (12%+), highly viscous<\/span><\/td>\nDuring the later stages of concentration, viscosity rises sharply, the heat transfer coefficient decreases, and coking is likely to occur.<\/span><\/td>\nWall-scraping agitation, large discharge port, online viscosity monitoring<\/span><\/td>\n<\/tr>\n

The above process parameters are based on established industry practices for the extraction and concentration of Polygonatum.<\/span><\/p>\n

III. Optimized Design for Polygonatum Materials<\/span><\/strong><\/p>\n

    \n
  1. \n

    Anti-foaming and Anti-Leakage<\/span><\/strong>: The diameter of the evaporation chamber is increased by 30% or more; the secondary steam flow velocity is controlled at 1 m\/s or less; a mechanical defoaming device is available as an option; and the material loss rate is controlled within 1%.<\/span><\/p>\n<\/li>\n

  2. \n

    Prevents burning and sticking to the sides<\/span><\/strong>: Variable-frequency scraping agitation; during the later stages of concentration, the system automatically switches to low-speed scraping to keep the heating surface clean, ensure stable heat transfer efficiency, and prevent localized overheating.<\/span><\/p>\n<\/li>\n

  3. \n

    Low-Temperature Protection<\/span><\/strong>: High-efficiency vacuum system, with a vacuum level stabilized at -0.09 MPa and an evaporation temperature of approximately 60\u00b0C, resulting in a significant increase in the retention rates of Polygonatum polysaccharides and saponins.<\/span><\/p>\n<\/li>\n

  4. \n

    Thorough cleaning with no blind spots<\/span><\/strong>: The CIP rotating spray ball covers all surfaces of the tank, piping, and evaporator, and can be used for riboflavin validation to ensure effective cleaning.<\/span><\/p>\n<\/li>\n

  5. \n

    Data Traceability<\/span><\/strong>: The PLC records temperature, vacuum level, time, and specific gravity; batch data can be exported, facilitating process optimization and quality traceability.<\/span><\/p>\n<\/li>\n<\/ol>\n
