The software for the humidity probes of BONFANTI dryers has been improved

Over the past few years we have developed a sensor for measuring the humidity of the cereal, in order to be able to control the drying speed and the production of BONFANTI dryers directly by checking the real humidity of the seed.These sensors were made by the Bonfanti company in the mid-1980s, over the years they have been updated in electronics and perfected in operation.

Some of the latest improvements are:

2018 we changed the type of electrical connection

2019 simplified some calibration operations

The search for perfection leads us to continuous checks and improvements.These humidity sensors are continuous reading, flow: it is in fact the flow of cereal that makes reading possible.The technological principle of operation of the sensors is “capacitive” and exploits the different electrical conductivity of cereals to provide very precise and repeatable values.

For the rapid operation and calibration of these probes, which are real measuring instruments, a software has been developed that is capable of interpreting the electrical values, providing numerical values ​​and capable of interacting immediately with the rest of the dryer control.The final calibration procedure is now very simple, the user quickly corrects the reading thanks to checks carried out with his own control machines in the laboratory.

The use of these true measuring sensors, humidity probes, applied in strategic positions inside the dryer, allows a real control of the drying process by increasing the quality of the seed and decreasing the need for control by the operator.

These humidity probes are particularly advantageous because:

– they do not need cleaning, it is the cereal itself that sliding on the stainless steel measuring walls keeps the sensor clean.

– can be applied inside the dryer, with maximum temperatures of 70 degrees and the presence of wet air and humidity

– duration over time.
