The Minibatt harvests, threshes and separates out the grains from the surrounding material. It uses a standard hulling technique in a standalone format.
The Minibatt is made up of a self-contained unit comprising a picker / threshing drum, an aerator / blower and its drive system, on the same horizontal axis. The machine is driven by an electric gear-motor, coupled to the end of the drive shaft and powered by a rechargeable battery.
A miniature combine harvester
The minibatt is started using a trigger which controls the motor via an electronic variable speed drive with mechanical pre-sets. The operator carries the machine in one hand whilst using the other to operate a flap located above the picker / threshing drum to direct the ears of the crop onto the picker. The ears are caught by the fingers of the picker which remove the grains by combing. The sample is then threshed using a concave. The aerator sucks air from the outside through an adjustable air intake opening and blows it into a transverse duct. The sample passes through the concave and crosses the air flow in the transverse duct, which opens to the outside. The grains are separated from the surrounding material, which is ejected. The grains drop down and are collected in the sampling container.
