“Borun Wet Process” has been developed by our team of professional technicians through years of research and refinement. It is a departure from the traditional dry milling adopted in China of smashing dry grains and then adding water for size mixing prior to pulverization, fermentation and distillation. Our Borun Wet Process instead involves first steeping and then de-germing the corn kernel after which we smash the residual meterial with a colloid mill prior to fermentation and distillation. We believe we are the only edible alcohol manufacturer utilizing this technology in China. The State Intellectual Property Office of the PRC has accepted our application for a patent of invention for our wet process and the patent is undergoing final approval process.
Through the implementation of our self developed production process, we have the ability to extract corn germ from the corn, enabling us not only to generate revenue from the sale of such corn germ but also to save on energy costs by removing corn germ from the process. The extraction of corn germ reduces the content of fusil oil in the alcohol, which improves the purity of the product and taste. During the traditional method, corn germ remains in the process and is ultimately converted into corn germ lipids (fats), the presence of which during a later stage of waste water treatment inhibits the production and output of methane. Since we recycle methane through an anaerobic process to supplement our fuel needs (for heating our boilers, for example), the absence of corn germ (and thus, corn germ lipids) in the Borun Wet Process during such water treatment stage increases our yield of methane, thereby reducing our dependence on coal for our energy needs.
We believe the key to our gradual improvement on our production technology is our understanding nd control of temperature and acidity as well as other key paraments during each stage of the production process. This understanding and application requires continuous and long-term research by our technical professionals as well as the timely inspection, adjustment and replacement of key components of our equipment.
We are also currently developing a process for implementation in Phase III at our Daqing facility where we will ferment raw corn directly which will reduce our energy consumption and enhance our production yield.
Borun also has modern production lines with state of the art equipment. For example, we now utilize five-tower fermentation and distillation equipment which enables us to produce a higher grade (Grade B) edible alcohol as opposed to the three-tower equipment which generally produces ordinary grade (Grade C) edible alcohol. Most edible alcohol producers in China have three-tower equipment and thus our Borun Wet Process produces a purer, higher quality product which we believe will increase our popularity among customers.
