The Food Radar System

All system components are hygienically contained. The entire system takes up about one meter of pipe length and is very quick and easy to install. It consists of the following:

1. Operator panel.     2. Rejection unit.     3. Buffer pipe.     4. Sensor unit.    

The operator panel consists of a computer with a touchscreen interface. There is no need to calibrate the system for all your different products. It is normally enough with just two product group categories: smooth or particulate. The system is very user-friendly and the operator only needs to choose the right product group setting. The operator panel also provides statistics on the rejects and production time, as well as a display showing the product flow background noise and the threshold. When an object is detected, the signal crosses the threshold and the object is automatically rejected.

The sensor unit includes a sensor head and a specially developed industrialized vector network analyzer (MTRX) that is controlled by the computer and generates a microwave signal. This microwave signal is then fed to the sensor head. The system measures the dielectric properties of the food flow. If an object differs from the norm, it is detected and rejected from the flow via the valve that opens in a fraction of a second. The exact speed of the foreign object is also measured to ensure a safe reject and still limit the rejected volume to a minimum.

The Food Radar system is designed for clean-in-place (CIP) and does not have any moving parts. A permanently installed system causes no extra turbulence or flow resistance.
