A modified flow line for eggs sorting by geometric parameters and forms is discussed in the paper. A method for eggs sorting by shape factor allowing to remove sub-standard eggs is proposed. Also the algorithm for determining the geometric parameters of the eggs using a vision system is considered. The fundamental difference of experimental installation for automatic eggs sorting on the category from existing sorting machines, that share eggs on a category by weight, is separation of eggs on a categories by size and separation substandard eggs in the stream. In the experimental installation mechanism for moving the eggs dismantled and replaced to an endless rope transporter with independent frequency-controlled electric drive. As a result of the experimental verification of system parameters of technical vision on the experimental installation showed that the time required for classification of the eggs is not more than 340 ms.
