Design of the highly active salting egg can's control system based on ARM

摘要

In order to improve the mass transfer rate of salt to eggs and increase the efficiency of salting eggs, the can of highly active salting eggs based on ARM was designed, adopting physical measures including pulsed pressure; heating; using ultrasonic wav and so on to change the stress field; the field of permeating and the concentration field. The automatic control system of salting can is comprised of ARM microcontroller; the module of pressure measuring and controlling; the module of temperature measuring and controlling and the module of ultrasonic wav. In order to test the stability of the salting egg can, experiments were done and results showed it works reliably and stably. Compared with the traditional salting eggs methods at the same time, the efficiency was increased to about five times in the 14% salted water.
