Mechanization mega trendHarvesting fruit requires manual labor: Pieces of fruit grow sporadically on crooked branches and twigs, and they need to be picked carefully. In order to automate the complex process, new machines replicate the human hand with mechanical grippers. A complex control system ensures a very refined grip. However, this process is slow and requires multi-stage intricate mechatronics.
But it is much easier to suction the fruit. An approximate approach is sufficient when using a suction tube. The lack of a firm grip means the risk of pressure points is eliminated. The hose and collecting baskets are made of soft material so that the sensitive products can enter the transport boxes undamaged.
Quick and easyThere are already harvesters with suction pipes that take the fruit directly from the trees. However, approaching the individual fruits also requires time and a rather complex mechanism. Technically speaking, the semi-automatic solution is much simpler: Human harvesters stand on a mobile and height-adjustable platform from where they can easily reach the fruit on the espalier trees. They place the fruit in a soft basket in front of a flexible suction pipe. The fruit is sucked in from there and transported away through the hose.
There is no need to use ladders, baskets and boxes, and constant bending and walking here and there is also avoided. A helper can harvest many times more in a given period of time than they would in the conventional way. This suction technique has long been standard for harvesting nuts. They are shaken from the trees or bushes and collected with "nut suckers".
Depending on the fruit and the type of machine, different sized vacuum pumps are required to supply the vacuum for the suction processes. offers a wide range of suitable solutions for this purpose.
