玉米淀粉

1. 净化:储存前去除大小杂质。旋转筛进行去石和除尘。净化后的玉米被送往浸泡工段。
 
2. 浸泡:逆流浸泡在约50°C的循环酸浸槽中,使玉米软化。浸泡后的玉米随后被泵送至粉碎工段。
 
3. 亚硫酸制备:硫在熔炉中燃烧,产生二氧化硫气体,该气体在塔中用水吸收,生成亚硫酸。

4. 玉米粉碎和胚芽分离:浸泡后的玉米被研磨,并送往胚芽分离旋风分离器和筛子。进一步研磨可提高分离效果。轻相返回到之前的槽中。

5. 精磨和纤维加工:脱胚玉米经过精磨去除纤维。纤维经过清洗、脱水、干燥,并与玉米浆混合,制成动物饲料。

6. 蛋白质分离与淀粉清洗:淀粉乳经初级分离器去除麸质。清洁的淀粉经过12级水力旋流清洗工艺。

7. 淀粉脱水与干燥:精细淀粉乳经刮刀离心机脱水,再经气流干燥机干燥,使水分低于14%。最终产品包装运输。

8. 胚芽加工与榨油:胚芽经清洗、脱水、干燥、油炸,然后榨油。毛油经过滤后备用。
 
9. 麸质浓缩与干燥:麸质经气浮罐浓缩,经真空过滤脱水,干燥后制成麸质粉。

10. 水回收与浸泡液蒸发:浸泡液经蒸发器浓缩后与纤维混合,用于动物饲料。工艺用水可重复用于浸泡和清洗。

Description of Investment Components:

  • Machinery:
    The machinery investment includes core equipment required for corn starch production such as corn cleaning and steeping units, wet milling systems, fiber separation, germ recovery, gluten separation, starch refining, drying systems, storage silos, slurry handling, CIP (Cleaning-In-Place) systems, and all related process lines and automation systems.

  • 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, laboratory units, social facilities, and landscaping areas suitable for the full operation of a corn starch factory.

  • Total Investment:
    The total investment estimate encompasses all vital components such as detailed process engineering, mechanical and electrical installation, infrastructure setup, environmental protection units, product handling systems, licensing, and utility connections (electricity, water, gas) essential for continuous, large-scale operation.

  • 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 and must be quoted separately based on specific capacity needs.

  • Project Design:
    Project planning, feasibility studies, and factory layout design services are provided independently and are not included in the above investment figures. These services can be customized according to local regulations, raw material availability, and market targets.

  • Technical Service & Consulting:
    Turnkey installation is included within the investment scope. Post-commissioning remote monitoring, process optimization, and technical support services will be provided free of charge for a period of 700 days following plant handover.
