What is steam tableting? Rjc China Feed Industry Information Network - based on feed, serving livestock

Steam tableting is a processing method with a high processing cost. The method is to input the grain into the steam box and steam for 30 minutes to 60 minutes to fully gelatinize the grain starch. When the grain moisture is increased to 18%-20%, the grain is further rolled into a pre-heated large roll. Rjc China Feed Industry Information Network - based on feed, serving animal husbandry

Steam pressing process: raw materials → cleaning → steam heating and tempering → tableting → drying, cooling → packaging → finished product storage. Rjc China Feed Industry Information Network - based on feed, serving animal husbandry

The process of steam tableting is relatively simple. The purchased raw materials need to be cleaned up. The cleaning includes removing impurities, small impurities, light impurities, stones, metals, etc. The cleaned raw materials enter the quenching tank, after a period of time, The corn starch is fully gelatinized and then pressed into a tableting machine. The thickness of the tablet can be adjusted, and then the drying cooler is allowed to lower the temperature of the material, and the moisture is lowered to safely store moisture. At this time, the materials can be packaged into the warehouse, or combined with other feeds such as grass, cottonseed, and powder, and then packaged into the warehouse or directly delivered to the farm in bulk.

The process of steam pressing is simple, so the processing cost does not exceed granulation. Rjc China Feed Industry Information Network - based on feed, serving animal husbandry

The mechanism of action of steam tablets Rjc China feed industry information network - based on feed, service animal husbandry

Steam Compressed Grains are processed by steam hot working to swell and soften the grain, which is then peeled off by mechanical pressure generated by a pair of counter-rotating drums to fracture the expanded grain and process the grain into sheets of specified density. The mechanism of steam tableting to treat cereals is actually a gelation process, that is, the tightly bound type of cereal starch, which gels to destroy the intracellular starch-bound hydrogen bonds, thereby increasing the digestibility of the animal's starch starch. In addition, during the steam tableting process, the chemical structure of the protein in the grain is changed, which is beneficial to the absorption of protein by the rumen of the ruminant. The factors that promote the gelation process and improve the overall digestibility of steam tableting are mainly water, heat, treatment time and mechanical action. The action of water is to expand and soften. Heating can cause electrons to move and destroy hydrogen bonds. To promote the gelation reaction, sufficient steam conditioning time is the guarantee for obtaining a sufficient gelation process. The mechanical action of the drum is a process of crush molding and reaching the specified tablet density. Rjc China Feed Industry Information Network - based on feed, serving animal husbandry

Effect of steam-pressed grain on lactation performance of dairy cows - News - Global IC Trade Starts Here - ICEach.

Steam-pressed cereals increase starch digestibility in the rumen, small intestine, and whole digestive tract compared to dry milling, and increase as tablet density decreases. The increased utilization of carbohydrates in the rumen is essential for efficient and maximal growth of rumen microorganisms. On beef cattle, steam tableting has been reported to increase the efficiency of conversion of feed proteins to microbial proteins. There are similar reports on cows. The digestion of starch in the rumen affects the energy supply, which in turn directly affects the synthesis of milk. Processing the grain increases the rumen's available carbohydrates, increasing milk production, milk protein rate and yield.

Application status of steam tablets at home and abroad Rjc China Feed Industry Information Network - based on feed, serving animal husbandry

In the developed countries of animal husbandry such as Europe and the United States, steam tablet processing technology has been widely used in dairy cattle, beef cattle and mutton sheep for 20 years. There are 98 million fenced fattening beef cattle in the United States, and 100% beef cattle fattening farms use steam-pressed cereals. In the past five years, the number of dairy farms using steam-pressed cereals has reached 60%-70%. In recent years, our neighboring South Korea and Japan have also started to use steam-pressed grain feed to feed cattle and sheep. Cattle feed accounts for about 25% of the total feed, while steam tablets account for almost the vast majority. As early as in the "7th Five-Year Plan" and "Eighth Five-Year Plan", China mentioned the steam tableting technology, and the steam tableting machine was jointly developed by the Wuhan Academy of Food Science and Technology and the Wuxi Academy of Food Science and Technology. The domestic cattle and sheep breeding industry has not been formed. It has not been promoted since the completion of the research. At present, there are some professional magazines and papers on this technology in China, but it is rarely used in production. China's cattle industry is still a relatively traditional way of raising cattle, mainly sporadic stocking, or the large-scale cattle industry has just started, its feed is currently concentrated in grass feed and mixed with some powdery concentrate.

The application prospect of steam tableting in China Rjc China Feed Industry Information Network - based on feed, serving animal husbandry

Feed is the material basis for the development of animal husbandry. In addition to the need for a large number of high-quality pastures, the development of cattle raising in China requires a large amount of concentrate to ensure. The development of beef cattle and dairy cows will consume a lot of feed. At present, although we can take part of the grain to develop animal husbandry, it is still necessary to develop steam tableting in order to reduce production costs and increase the utilization rate and conversion rate of existing feed. Steam compression and quenching treatment is currently the most ideal corn processing technology for feeding. Compared with other processing methods, it can significantly improve the utilization rate and conversion rate of feed corn. At present, this technology is widely used in foreign countries for the treatment of cows and beef cattle. Feed corn.
