The first domestic curing yeast project of Jilin Fuel Ethanol Company started successfully
Analysis of the data shows that the feeding trial, one day ahead of schedule, produced qualified products, and the indicators met the design requirements.
Immobilized yeast project, is the company's most complex process in this year's technical transformation, a project with a greater impact on improving quality and efficiency. By using tens of thousands of floating balls at the top of the tank to adsorb yeast for propagation, multiple batches of fermentation do not need to pitch new yeast, changing the previous method of needing to re-pitch yeast activation after each pre-fermentation tank is emptied after fermentation, which is a new technology and breakthrough in biological science.
The person in charge of the project said that such technology realizes yeast one-time input, no need to continuously cultivate seeds, reduce yeast addition, simplify the process and operation, and also can effectively solve the problems of difficult yeast cell recovery, high apoptosis rate and poor stability; compared with the traditional activation process, the amount of wastewater generated is also greatly reduced, which is in line with the direction of national energy saving and carbon neutral policy.
Before pitching, the company's relevant personnel and the technical manufacturer had many exchanges and drive-throughs, and every step of the operation was well thought out and repeated, especially in preventing the fermenter from staining bacteria, and several specific measures were made to deal with various conditions that might occur.
In addition, they also conducted a comprehensive and detailed safety inspection before commissioning the project to ensure that all operations were safe and under control after commissioning.
During the start-up process, they had to keep the process index of each process of the plant unaffected while taking into account the start-up operation of the project. After 48 hours of careful tuning, the immobilized yeast technical reform project was successfully started at once.
The person in charge said that after the completion of the project, it will promote the enterprise to improve quality and efficiency to a higher level, and at the same time can play a role in promoting the research and development in the field of fermentation technology for other similar enterprises in China, which has significant social benefits and demonstration effect of scientific and technological innovation.
JIN DUN CHEMICAL has built a special (meth) acrylic monomer manufacturing base in ZHEJIANG province. This makes sure the stable supply of HEMA, HPMA, HEA, HPA, GMA with high level quality. Our special acrylate monomers are widely used for thermosetting acrylic resins, crosslinkable emulsion polymers, acrylate anaerobic adhesive, two-component acrylate adhesive, solvent acrylate adhesive, emulsion acrylate adhesive, paper finishing agent and painting acrylic resins in adhesive.We have also developed the new and special (meth) acrylic monomers and derivatives. Such as the fluorinated acrylate monomers, It can be widely used in coating leveling agent, paints, inks, photosensitive resins, optical materials, fiber treatment, modifier for plastic or rubber field. We are aiming to be the top supplier in the field of special acrylate monomers, to share our rich experience with better quality products and professional service.
