Rice distillers dried grains with soluble (DDGS) are the by-product of utilizing rice as a raw material to make ethanol. It is much prized as it serves as a wholesome energy source for many animals.
Nutrigo Feeds Pvt. Ltd. used the best methods for the rice DDGs manufacturing process. Following the fermentation of rice, the residual solid ingredients are dried. Rice DDGS is a high-protein and high-caloric ingredient that can be used for animal feed. In this blog, we will be talking about the Rice DDGs production process in India.
Export Market for Rice DDGs in India
The global need for animal feed and the growing popularity of bio fuels have led to significant growth in the Indian rice DDGS export market. The efforts to increase cultivation and facilitate shipping have increased the competitiveness of the Indian rice DDGS export market.
In 2025, the Indian DDGS feed market is anticipated to reach $0.57 million, and the country’s laws regarding the export of rice may have an effect on the DDGS export industry. Since sustainability is becoming more and more important to people worldwide, selling rice DDGS promotes economic growth and environmental goals by making better use of available resources.
The Rice DDGs Production Process in India
- Milling Rice
The initial step in this procedure is polishing the rice, which removes the bran and germ from brown rice to make it white.
- The Fermentation Process
To improve the activity of the enzymes, the primary ingredient—typically rice or rice bran—is crushed into a fine powder. When rice is milled, enzymes such as glucoamylase and alpha-amylase are added to convert the starch into ferment able sugars, mostly glucose.
- The Distillation Process
Three ingredients make up the fermented mass (beer): water, alcohol, and trace amounts of fermented grains, proteins, and fibers. It is brought to the distillation apparatus, where the ethanol has already been separated from the water and solid wastes. The remaining liquid and solids are treated once more, and the ethanol is collected and further cleaned up.
- Centrifugation
To separate the solid portion (wet distillers grains) from the liquid portion (thin stillage), the stillage is placed in devices known as centrifuges. The remaining processing liquid is often thickened by machinery to create a syrup with dissolved materials.
- The drying Process
In order to remove the water, the grains and syrup in the wet distiller are combined and dried using devices such as rotary drum dryers. For the DDGS to have the proper moisture content and nutrients, the drying temperature and duration must be properly regulated.
- Verifying Packing and Quality
To ensure high quality, the final DDGS product is examined for nutrients such as protein, fiber, fat, and moisture. After quality has been guaranteed, the DDGS rice was cooled, dried, and packed in proper containers or large bags for storage as well as transportation.
Important factors to consider in the Manufacturing Process of Rice DDGS
- The enzymes’ effectiveness affects the output and quality of ethanol production as well as the DDGS animal feed.
- For the production of high-quality DDGS and excellent ethanol, the proper temperature, acidity, and duration must be maintained.
- For the product to retain its nutrients and remain for a long time without becoming mouldy or damaged, proper drying is essential.
- To manufacture high-quality DDGS, it is crucial to ensure that as many nutrients as possible are retained during the drying process, particularly proteins and amino acids.
- In dried form, rice DDGS has a substantial quantity of protein (between 25 and 30 percent).
- One feed ingredient, rice DDGS, and provides a high value of energy in its sources. It contains fat of about 10-12% and 65-70% of total digestible nutrients when dried.
- It is an economical option that is cheaper as compared to regular animal feeds like corn & soybean meal.
Conclusion
A few crucial phases are included in the manufacturing process of rice DDGS , such as grinding the rice, fermenting, distilling the liquid, spinning it to separate the components, drying it, and assessing its quality. Moreover Making a high-quality, nutrient-dense feed component that supports the health of various animals requires careful consideration of each stage. Nutrigo Feeds adopted the best Rice DDGs production process in India for clients and their animals by utilizing modern technology and quality control.
Frequently Asked Questions
Q.1 How is DDGS produced?
Ans. A by-product of the production of alcohol is rice DDGS. In order to produce alcohol, distillers separate the starch from grains. The nutrients that remain are mostly vital proteins, fats, and vitamins that are good for cow and poultry feed.
Q.2 What are the quality standards for the rice DDGs production process in India?
Ans. The Bureau of Indian Standards (BIS) has established guidelines for DDGS about the amount of moisture, protein, fiber, and other components it must contain.
