Abstract: In order to further improve the salting quality of salted eggs and shorten the salting time, a small automatic and fast salting device was designed based on the traditional ultrasonic-pulsed pressure technology, and the design of the device and the realization of the control system were discussed intensively. The device provided a good environment by realizing the function of positive and negative pressure pulse changes, keeping constant temperature, providing ultrasonic, circulating water. The control system of automatic and fast salting device was comprised of Delta DVP-SS2 programmable logic controller and Delta DOP-7S touch screen. Experimental results showed that this device could operate steadily and provide visualization platform, and it cut the salting time to 2 days. Compared with ultrasonic-pulsed method, the salting time was shortened by 33.3%, with no eggshell breaking, honeycomb proteins, proteins yellowing, which verified the feasibility and rationality of the proposed device.
