山梨糖醇
调配:生产工艺首先使用反渗透 (R.O) 水将葡萄糖浆浓度调节至约 45-50%。达到所需浓度后,加入碱性溶液,调节 pH 值并将其稳定在所需范围内。pH 值调节完成后,将特定催化剂引入混合物中,以促进即将发生的氢化反应。
氢化:预处理后的葡萄糖浆被泵入高压氢化反应器。在受控条件下——包括合适的温度、压力和持续通入氢气——葡萄糖分子发生催化氢化反应。在此阶段,葡萄糖在预定的反应时间内转化为山梨醇。
沉降:氢化反应完成后,将含有悬浮催化剂颗粒的粗山梨醇溶液转移至沉降槽。在这里,催化剂沉降并与山梨醇溶液分离,从而实现催化剂材料的回收和再利用。
过滤:部分纯化的山梨醇溶液随后经过过滤过程。此步骤可去除沉淀后悬浮在溶液中的任何残留催化剂颗粒或杂质。
脱色:为了改善产品的外观和纯度,山梨醇溶液需使用活性炭进行脱色处理。此步骤可有效去除有色物质和有机杂质。
离子交换:脱色后的山梨醇溶液通过离子交换树脂。此处理可去除溶解盐、金属离子和残留有机化合物,显著提高最终产品的化学纯度和质量。
蒸发:最后,通过蒸发多余的水分对纯化的山梨醇溶液进行浓缩。此蒸发过程可将山梨醇含量提升至所需浓度,使其适合根据产品规格进行包装、储存或进一步加工。
Description of Investment Components:
-
Machinery:
The machinery investment includes the essential equipment required for sorbitol production, such as starch slurry preparation systems, enzymatic hydrolysis reactors, vacuum evaporators, crystallizers, dryers, filtration systems, blending units, CIP (Cleaning-In-Place) systems, and all related process lines and automation systems. These machines ensure efficient conversion of starch or glucose into sorbitol and the subsequent drying, refining, and packaging of the final product. -
Land & Construction:
The land and construction costs cover industrial-zoned land and all necessary physical infrastructure, including production buildings, administrative offices, raw material and finished product storage areas, laboratory units, social facilities, and landscaping areas. These facilities are designed to support the full operation of the sorbitol production plant, ensuring that the production process from raw material intake to final product storage and distribution is seamless and efficient. -
Total Investment:
The total investment estimate includes all essential components such as detailed process engineering, mechanical and electrical installation, infrastructure setup, environmental protection units (e.g., wastewater treatment), product handling systems, licensing, and utility connections (electricity, water, gas). These components are vital for establishing a continuous, large-scale sorbitol production facility that can operate efficiently and in compliance with industry standards. -
Auxiliary Equipment:
Auxiliary systems such as steam boilers, cooling towers, air compressors, water purification systems (e.g., reverse osmosis), control panels, backup power generators, and utility monitoring systems are not included in the machinery prices listed above. These systems must be quoted separately based on the specific capacity and operational needs of the facility. -
Project Design:
Project planning, feasibility studies, and factory layout design services are provided independently and are not part of the above investment figures. These services can be customized according to local regulations, raw material availability, and market targets. They are essential for ensuring that the facility is designed for optimal efficiency, regulatory compliance, and cost-effectiveness. -
Technical Service & Consulting:
Turnkey installation is included within the investment scope. After commissioning, remote monitoring, process optimization, and technical support services will be provided free of charge for a period of 700 days following plant handover. This ensures that the plant operates at peak efficiency and that any technical issues are promptly addressed to maintain continuous operations.
