Safety first. Prevention first – let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Great Development in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** On June 24, 2024, Jilin Fuel Ethanol Company completed the production of the first batch of high-quality fermented broth using its domestic fixed yeast system. After 3 days of operation, all parameters met the expected standards, marking a successful launch of this pilot project for fixed yeast technology. As the first solidified yeast project in the country, the company’s technical staff, facing challenges such as insufficient process adaptability, carefully reviewed past experiences and meticulously planned and implemented a series of measures to overcome these bottlenecks. After a month of intensive preparation and modifications, they successfully avoided the issue of insufficient supply resulting from supplying the mash to both the immobilized yeast fermentation process and the original production system, by adopting innovative measures such as adding feed pipelines for the immobilized yeast tanks. This ensured the stability of the parameters after mixing the materials from different fermentation processes. To ensure the smooth progress of the technical improvement project, the company has implemented strict quality assurance measures. Before putting the immobilized yeast tank into use, technicians carried out cleaning and rinsing cycles in alternation to ensure that the float carriers were clean and sterile, thereby creating an optimal environment for the thousands of floats inside the tank to absorb yeast and promote its growth. During the experimental process improvements, the technical staff developed a scientific and reasonable yeast activation plan, which was carefully optimized to effectively minimize the negative impacts on the original process flow and achieve better compatibility with the existing processes. As verified through actual production, key parameters such as reducing sugar, residual total sugar, and alcohol content in the fermented mash improved significantly; the amount of yeast required was greatly reduced, resulting in notable improvements as a result of these technical adjustments. Next, Jilin Fuel Ethanol Company will continue to intensify efforts to optimize its production processes, promote the ongoing use of immobilized yeast technology, and thus provide impetus for fully achieving the goals of improving quality, enhancing efficiency, and turning losses into profits.
