PRISM - PuRification and Isolation of Shell Membranes

全球约30%的鸡蛋产量在破碎厂加工，以生产商业和消费者液体蛋产品。高通量破碎机每秒可处理超过三个鸡蛋，同时破碎，清空，收集鸡蛋内容物，并转移蛋壳进行处理。这些机器排出的破碎蛋壳（包含蛋壳和蛋壳膜（ESM））主要作为土壤改良或饲料补充的肥料出售。最近对ESM的研究已经证明了其潜在的临床益处，并刺激了许多用于关节疼痛，伤口愈合和皮肤护理的创新健康产品的开发和营销。然而，目前从排放的混合物中商业收集无害环境管理涉及基于空气或水的浮选方法和酸处理以从无害环境管理中去除外壳。从产品质量到产生具有高生化需氧量的化学和水性废物，这些技术存在若干缺点。为了解决这些缺点，我们的团队发明了一种新的工具，可以直接从蛋壳中机械地提取ESM，而不需要化学品或大量的水。该项目的目标是将这种成熟的技术应用于原型鸡蛋破碎机。概念验证的成功创建将证明其在工业环境中的实施是合理的，并刺激了专注于ESM提取的自动化鸡蛋破碎自动化机器的开发。

About 30% of the global production of chicken eggs are processed at breaking plants to produce commercial and consumer liquid egg products. High-throughput breaking machines can process over three eggs per second while breaking, emptying, collecting the egg contents, and diverting the eggshells for disposal. The crushed eggshells, which contain both the shell and the Eggshell Membranes (ESM), discharged by these machines are then mainly sold as fertilizer for soil amendment or feedstock supplement. Recent research on ESM has demonstrated its potential clinical benefits and has spurred the development and marketing of numerous innovative health products for joint pain, wound healing, and skin care. However, current commercial collection of ESM from the discharged mixtures involves air or water-based flotation approaches and acid treatments to remove the shell from the ESM. There are several disadvantages of these technologies from product quality to the generation of chemical and aqueous waste with high biochemical oxygen demand. To address these shortcomings, our team has invented a new tool for extracting the ESM directly from the eggshell mechanically, without the need for chemicals or large quantities of water. The goal is of this project is to incorporate this proven technology in a prototype egg breaking machine. The successful creation of a proof-of-concept will justify its implementation in an industrial context and spur the development of an automated egg breaking automated machine focused on ESM extraction.
