7.2 SORTING/TRANSPORTING PROCESS
The sorting process begins by placing fruits/vegetables on the belt.
- Activate the machine (see section 6.1 for a description of the procedure).
- Select the desired function mode and start the conveyor/processing line (see section 7.1 for more information
about the working modes).
- The speed can be regulated with the frequency regulator assigned to the conveyor located at the control
panel (no matter what function mode has been selected).
- Begin the sorting process by removing manually poor-quality fruits/vegetables.
- The machine will transport fruit/vegetables automatically to its destination.
- The sorting and transportation process is done.
7.2.1 SETTING THE HEIGHT AND THE INCLINATION
The height and inclination of the machine are factory-set, but they can be modified if ever needed.
Setting the height
- To set the height it is necessary to loosen the screws shown in the picture below, then select the desired
height and tighten the screws again. This procedure has to be performed in both legs of the machine.
Setting the inclination
- To set the inclination it is necessary to loosen the screw shown in the picture below, then select the desired
inclination and tighten the screw again. This procedure has to be performed in both sides of the machine.
Depending on the layout of the processing line, some sorting conveyors will not have a frequency
regulator and they will have a proper default speed for its function.

18
7.2.2 ADJUSTING THE TENSION OF THE BELT
The tension of the belt is set by the manufacturer but it can be modified if ever needed.
Sometimes occurs that the belt looses tension due to the weight of the fruit load.
To adjust the tension proceed as follows:
- Localize the upper screws in both sides of the conveyor (shown in the picture below).
- Use a 13mm wrench in order to tighten or loosen the screws and therefore the belt tensioner.
- By turning the screws clockwise the belt tensioner tightens, in the same way, by turning the screws counter
clockwise the belt tensioner loosens.
The same actions have to be performed on both sides! (e.g. If the right screw is turned clockwise 3
times, the left screw has to be turned clockwise 3 times as well). This will ensure uniform tension.
