Abstract: In order to meet the industrialization and modernization of pond aquaculture, and improve the mechanical automation of cultivation, a set of automatic feeding system was designed based on the principles of pneumatic conveying, which takes programmable logic controller as controller. This paper mainly introduced the composition and working principle of feeding equipment system, the key technologies such as pneumatic conveying, multi-channel distribution, automation control been analysed as well. According to the design requirements, 320 m length of transporting tubes were for performance test, with the biggest suitable amount 1 100 kg/h, the tons of material consumption below 8 kWh/t and the feed broken rate lower than 0.7%. Results of test and practical application show that the feeding system is reliable and efficient, easy to operate, with which, timing, quantitative and high efficient feed can be realized.

Key words: pond aquaculture; feeding system; pneumatic conveying; automatic control
