This invention discloses a method for preparing high-performance egg liquid and a screening device for the preparation, including a frame, a screening mechanism, a cleaning mechanism, a
drying mechanism, a feeding conveyor, a qualified egg unloading
machine, an unqualified egg unloading
machine, and a
robotic arm. The screening mechanism includes a screening frame, an upper
linear actuator, an upper detection cylinder, a
pressure sensor, an air inlet
pipe, a liquid inlet
pipe, an air
inlet valve, a liquid
inlet valve, a weighing sensor, a weighing cylinder, a
piston, and a lower
linear actuator. The cleaning mechanism includes a power pump, a
liquid storage tank, and a liquid delivery pipeline. The
drying mechanism includes a fan and an air supply
pipe, with the fan connected to the air inlet pipe via the air supply pipe. By measuring the
specific gravity of the eggs to determine their quality, relatively fresh eggs with intact internal components can be accurately selected, making this judgment standard more scientific and accurate. The screening device can automate the feeding, screening, cleaning,
drying, and unloading of eggs, with each step performed continuously without the need for intermediate transfers, resulting in higher efficiency.
