Discrete Element Method (DEM) parameter calibration is fundamental, providing a high-fidelity simulation environment for particle interactions. This involved meticulous measurement of physical properties like density, elastic modulus, and Poisson's ratio, alongside empirical calibration of contact parameters such as friction coefficients and surface energy. The calibrated model accurately predicts complex behaviors like agglomeration and flow dynamics, enabling precise optimization of separation equipment.

Optimizing vibratory screening parameters is key to efficient egg separation. Through DEM simulations, we analyzed the effects of vibration frequency, amplitude, and cone pendulum angle on screening rate. Identifying optimal settings significantly enhances particle stratification and passage through screen apertures, reducing impurities while preserving egg integrity. Ultrasonic assistance further boosts efficiency by minimizing particle agglomeration.

Screening Rate Improvement with Ultrasonic Assistance
Enhancing Throughput with Optimized Vibratory Screening
A major biocontrol facility previously relied on manual screening, resulting in slow throughput and high labor costs. By implementing vibratory screens calibrated with our DEM parameters, and operating at the identified optimal frequency of 12 Hz and amplitude of 1 mm, they achieved a 78%·s⁻¹ screening rate, significantly increasing their daily processing capacity. This optimization alone reduced operational bottlenecks by nearly 50%, allowing for a scalable increase in Trichogramma egg card production. The addition of ultrasonic assistance further refined the separation, boosting efficiency by another 15% by mitigating particle agglomeration, a common challenge with insect eggs.
Pneumatic separation complements vibratory screening by leveraging differences in suspension velocities between eggs and impurities. This method relies on carefully calibrated airflow velocities to selectively remove lighter contaminants (scales, dust) and heavier ones (appendages). Defining a feasible air velocity window ensures efficient impurity removal without significant egg entrainment, contributing to a multi-stage, robust cleaning process.
