Data Sheet 1_Design and optimization of a shearing grinding device for efficient separation of eggshell and eggshell membrane.docx Yuan Chi (382599) Jiabao Lin (5258075) Yuxin Wang (414197) Yuhao Jia (18806156) Yujie Chi (11854413) Biotechnology biomass valorization eggshell membrane response surface optimization separation rate shearing grinding mechanism single factor experiment <p>Global poultry egg production reached 100 million tonnes in 2024, and eggshell membranes account for approximately 10% of total egg mass. Mass egg consumption produces enormous amounts of waste eggshell. Eggshell is a natural calcium source, while eggshell membrane contains abundant proteins; both can be further processed into high value-added products. Current eggshell-membrane separation technologies commonly suffer from high energy input, chemical pollution or low separation efficiency, restricting large-scale industrial application. To address this bottleneck, this work adopts a combined shearing-grinding crushing strategy, which makes full use of the brittle nature of eggshell and high toughness of eggshell membrane. Key components of a custom shearing-grinding separation device were innovatively designed for this process. A four-factor three-level Box-Behnken response surface methodology (RSM) was implemented, with eggshell membrane separation rate selected as the response indicator for parameter optimization. The RSM-BBD regression model exhibited acceptable fitting performance (adjusted R² = 0.8637, predicted R² = 0.6983, Adequate Precision = 12.729). Under optimized operating conditions (15% moisture content, motor speed of 1,000 r/min, feed mass of 51 g, rotor-stator gap of 1 mm), a maximum separation rate of 87.28% was achieved. The proposed shearing-grinding device features simple structure, low energy consumption and environmental compatibility. This study offers a feasible technical route for the efficient industrial separation of waste eggshell and eggshell membrane, and supports the high-value valorization of poultry biomass waste within a circular economy framework.</p> 2026-09-21T04:28:41Z Dataset Dataset 10.3389/fbioe.2026.1928807.s001 https://figshare.com/articles/dataset/Data_Sheet_1_Design_and_optimization_of_a_shearing_grinding_device_for_efficient_separation_of_eggshell_and_eggshell_membrane_docx/33948952 CC BY 4.0
