1. Development process

The development history of corn starch carries the trajectory of mankind's continuous exploration and innovation of food processing technology. From ancient times to the present, the manufacture of corn starch has gone through many stages, evolving into the modern efficient and precise production process. The development history of corn starch has gone through continuous iterations of traditional processing, industrial revolution, technological innovation and sustainable development. From the initial basic physical processing to the modern efficient and precise production process, the manufacturing of corn starch has been continuously explored and innovated to meet the needs of human society for food and industrial raw materials.

Traditional processing era: In the early days of human history, corn, as the main source of food, underwent basic physical processing, such as rubbing, pounding, etc., for food processing and storage. However, due to technical limitations, traditional processing methods cannot meet the requirements for efficient separation of starch and other components, thus limiting the large-scale production and application of corn starch.

Industrial Revolution and Mechanization: With the rise of the Industrial Revolution, the application of mechanization technology has brought revolutionary changes to the manufacture of corn starch. At the end of the 19th century, steam-powered machinery began to be used in grinding and fine grinding processes, greatly improving production efficiency and product quality. The introduction of mechanization has accelerated the large-scale production of corn starch, providing abundant raw materials for food, textile, paper and other industries.

Technological innovation and modernization: At the beginning of the 20th century, with the development of chemical and biotechnology, corn starch production ushered in new technological breakthroughs. In the 1920s, the introduction of wet refining technology made the preparation of corn slurry more efficient and controllable. In the middle of the 20th century, the application of centrifugal separation technology further improved the separation efficiency of starch. In addition, the introduction of chemical methods and enzymatic hydrolysis technology makes the removal of proteins and impurities more precise and controllable.

Efficiency and green creation: In the 21st century, corn starch production is gradually becoming more efficient and green. The application of new technologies such as supercritical fluid technology and puffing technology makes the separation and purification of corn starch more efficient and environmentally friendly. At the same time, automated and intelligent production line design and control have improved production efficiency and consistency, and reduced human errors.

The direction of sustainable development: With the rise of the concept of sustainable development, the production of corn starch is also developing in a more environmentally friendly, energy-saving and low-waste direction. The introduction of environmental protection measures such as wastewater treatment and energy recycling has reduced the impact of the production process on the environment. At the same time, the concepts of green packaging and reuse are gradually integrated into all aspects of corn starch production, laying the foundation for the sustainable development of the industry.

2. Production steps and key technologies

1. Raw material processing and pretreatment

The cornstarch manufacturing process begins with the processing and pre-processing of raw materials, and the selection of raw materials plays a vital role in the quality and stability of the final product. Not only does it need to ensure the quality and maturity of the corn, but attention also needs to be paid to the geographical origin of the raw materials and agricultural practices to ensure the quality of the final product. The selection of raw materials involves multiple factors, including corn variety, growing environment, agricultural practices, and harvest time.

In the selection of raw materials, ensuring the quality and maturity of corn is the basis for manufacturing high-quality corn starch. Only by choosing corn with appropriate maturity and no pests and diseases as raw materials can we obtain high-content starch granules, thereby improving product yield and quality. The quality of corn is strictly controlled and can be evaluated through appearance, color, aroma and other indicators.

In addition to the quality of the corn itself, the geographical origin and agricultural practices of the raw materials cannot be ignored. The soil, climate and planting methods in different regions will affect the growth and quality of corn. Therefore, choosing a reliable agricultural supply chain to ensure that raw materials come from high-quality farmland and a healthy growing environment has an important impact on the quality and stability of the final product.

The geographical origin of raw materials and the choice of agricultural practices are closely related not only to the quality of the product in season, but also to its stability. Seasons, geographical locations and agricultural practices can cause changes in the properties of raw materials, affecting the consistency of the manufacturing process and final product. Choosing a stable raw material source can reduce this fluctuation and ensure the stability and quality of the product.

In the raw material processing and pretreatment stage, modern technology can play an important role in order to realize the tracking and control of raw material quality. For example, by using sensors and data analysis technology, key indicators such as the growth environment and maturity of corn can be monitored, thereby achieving real-time monitoring of raw material quality. These technical means can help producers better select raw materials and ensure the stability and quality of the final product.

In summary, raw material processing and pretreatment are important links in corn starch production, and the importance of raw material selection not only involves the quality and maturity of the corn, but also requires attention to the geographical origin and agricultural practices of the raw materials. By selecting high-quality raw materials and using the support of modern technology, the stability and high quality of the product can be ensured, thus laying a solid foundation for the success of corn starch production.

2. Submersion and slurry

The cleaned corn kernels enter the grinder and are mechanically broken into coarse particles to form corn syrup. This pulping process not only facilitates the execution of subsequent steps, but also significantly improves the separation efficiency of starch granules. Pulping makes the corn kernels more susceptible to subsequent processes, ensuring high starch purity.

3. Wet grinding

The ground corn steep liquor is mixed with an appropriate amount of water to form a suspension, which enters the wet refining equipment. Wet fine grinding uses the principle of hydraulic stripping to effectively separate ingredients such as starch, protein and fiber. The key to this step is to control the humidity and stirring intensity to ensure effective separation of the ingredients.

4. Separation and concentration

Separation and concentration are critical steps in the manufacturing process. Starch granules are separated from the mixture through methods such as centrifugation, sieving, and evaporation to obtain a dense starch slurry. Centrifugal separation is achieved in a centrifuge, where components of different densities are separated by different centrifugal forces.

5. Decolorization and deproteinization

Starch slurry may contain impurities such as pigments and proteins. In order to improve the purity of starch, decolorization and deproteinization become necessary steps. The application of enzymatic hydrolysis and decolorizing agent can remove pigments in starch slurry, while centrifugation and enzymatic hydrolysis can effectively remove proteins and make starch purer.

6. Dry

The decolorized and deproteinized starch slurry is sent to the drying equipment for heating and evaporation. By controlling the temperature and humidity, the water in the slurry is gradually evaporated to obtain dry starch granules. Drying is a critical step to ensure long-term storage and use of starch.

7. Crushing and packing

The dried starch blocks are crushed into powder and then strictly packaged. The packaging process requires great attention to moisture and contamination prevention to ensure the quality and stability of the final product.

3. Main equipment
