Usage area

The goal of goods inward testing in the acquisition and trading of grain crops is efficient sampling for correct evaluation of the deliveries. Sensitivity to foreign substances and lack of quality mean that the representativeness of the delivery samples must be ensured. Correct delivery samples are essential for quality control, documentation and retraceability. The Rakoraf 2 linear easily reaches any area of the vehicle to do this, e. g. while the vehicle is on the weighbridge.


The sample spear is pushed into the product using the remote control. When this takes place, a proper cross-sectional sample is pushed into the inner tube chamber of the sample spear. The Rakoraf operates using the patented Convac air circulation system. No suction effect is applied to the product. No lightweight fractions (e. g. broken grain, dust and dirt) are drawn in from the immediate vicinity. The air flow only takes the sample which is present in the sample spear and transports it to the weighing room or a laboratory through a PVC hose. There the sample is separated from the air in the reception box (collection container), emptied and is ready for quality control.


The Rakoraf 2 with a column or wall console is available with lateral movement (linear) with a maximum sampling area of 8.8x18.8 m or also fixed with a maximum radius of 4.4 m.
