Design of a Sprout Layer-rack Aeroponic Cultivation Device

摘要

A sprout layer-rack aeroponic cultivation device has been designed to solve the problems of low space utilization rate, large consumption of irrigation water, unbalanced growth amount and low automaticity in sprout production. SolidWorks has been employed to build 3D models for spare parts and the overall structure. Application tests have indicated that sprouts cultivated with this system grow well and produce basically the same growth amount in the upper and the lower layers. Compared with the traditional flat cultivation, the vertical cultivation can increase space utilization ratio by 300%. Compared with the traditional spray mode, the aeroponics cultivation mode can produce booming sprouts, with the root length increased by more than 30%, yield more than 20% and irrigation water saved by more than 40%. This system has been reasonably designed, reliably applied and easily used. After adjustment of the structural dimensions, this system can be applied to cultivation of spouts of different scales and thus shows great application prospect.
