Justification and calculation of design features of drum-type hydroponics

The purpose of the article is to evaluate design features rotary hydroponics and then obtain a method for calculating main technical characteristics. Drum (rotary) promising growing on artificial media. planting surface in this located inner cylindrical rotor rotating around lamp. has number advantages such as: smaller installation area due cylinder area; energy savings rational use light source; liquid saving formation nutrient solution alternate immersion roots more compact bath. In paper, theoretical aspects calculation drum hydroponic machines considered ensure highest productivity. As result, following characteristics was derived: determination required radius depending plant height; spots with known width rotor; minimum amount necessary solution; electricity consumed when using LED lamps.
