"The new product process requires that the reaction temperature should be controlled at -15 ℃, but at present the minimum refrigerant supporting the production line can only reach -10 ℃, and it is too late to replace the new equipment. What should I do?" "The use of instant water heaters in the bathroom of the Qiubin plant consumes a lot of energy, and the steam room drains a lot of waste heat. Can these two problems be solved together?" "The water station in each workshop produces and discharges a large amount of concentrated water from RO reverse osmosis units every day. How can this water be effectively used?" in the pharmaceutical production department, you can see such a person almost everywhere, wearing dark blue overalls, stepping on a pair of canvas shoes, with a smile on his face but always in a hurry, chanting these questions while walking. He is not like an ordinary person. He will turn his head and forget the passing thoughts. Instead, he will record the thoughts and problems in a notebook one by one, and then break them one by one. He is Ye Congcong, a group innovation expert in 2022, and a newly assessed young craftsman in Zhejiang Province.

"Brother Cong is the kind of person who, when seeing a new device, would want to go up and dismantle it to see the internal structure. Sometimes he is very persistent, and I think his persistence is especially worth learning." A colleague of Ye Congcong commented on him like this. "I have been working in Jianfeng Pharmaceutical for more than ten years, and I have been dealing with production facilities and equipment almost every day. Every equipment has its own charm, and I work on the side of attractive things every day, not to mention how happy I am." Ye Congcong said with a grin. Watching him talk about production equipment with a smile on his face and in high spirits, I was really infected by his deep enthusiasm for equipment and work.

In order to better understand Ye Congcong's working status, I followed him into the production area. When passing through the API workshop, he said with a little pride: "Look, this anti-tumor API production line has now completed process verification for three or four products. I also participated in the transformation of this production line at that time. It can be said that I watched the completion of this production line at 1.1 point. I was there from drawing design to equipment installation and debugging. I have encountered many problems in this process, but I have a motto, never give up easily when encountering problems, and must be fully breached!"

followed Ye Congcong from the synthesis area of the bulk drug workshop to the storage tank area of the comprehensive warehouse, stopping all the way, listening to him introduce the results of his transformation, feeling his love for his work, and seeing his outstanding ability as an innovative expert. When Ye Congcong learned about the low temperature requirement of the new product process for the reaction temperature and because it was too late to buy new refrigeration equipment, he first consulted the data and collected a large amount of information, calculated the head and flow rate of the external circulation pump of the independent refrigeration system used in the production of the anti-tumor bulk drug line lenvatinib, and proved the feasibility of the refrigeration system for the cooling of the new product, and proposed to transport the refrigeration system to the common bulk drug workshop through the pipeline, in parallel with the original public system of the new product reaction tank, and the use of special low-temperature insulation materials for the transmission pipeline insulation, the new product needs -15 ℃ reaction conditions. After the transformation, the test machine proved that the transformation results can meet the production of new products. This measure not only fundamentally solves the process problems, but also greatly improves the utilization rate of the refrigeration system.

In addition, Ye Congcong also reused the heat of steam condensate in Qiubin Factory and carried out centralized renovation of the bathroom. The waste heat discharged from the steam room was used to heat the water in the tank 24 hours by means of coil heating, so that employees could take a hot bath comfortably at any time. He also collected the concentrated water from the RO reverse osmosis unit of each water station as the circulating water (ice water) for each monomer workshop to make up water, equipment cooling and toilet water...

"Responding to the group's call to reduce costs and increase efficiency, as an employee of the engineering department, I have more equipment and more ideas. After receiving the support of the leaders, I turned my ideas into actions." When asked why he had so many good ideas, Ye Congcong said so. He also said that the idea of these small inventions and small creations is actually in the first place. Many people may have had it, but they did not grasp the inspiration. It is true, but not everyone can carefully consider the feasibility of this idea, constantly ponder the solution to the problem, and can also soak in the archives for half a day to check the information, and then take practical actions after formulating the solution.

Solve problems with innovation and achieve dreams with hard work. As long as you are good at observation and practice, small creation will also have big benefits. More small inventions and small creations will surely bring together a solid force to promote the high-quality development of enterprises. Cong Ge, who loves to solve difficult problems, is working towards this goal every day. (lisa liao)
