MJB Electronics Industries produce a comprehensive range of grain, potato, onion and vegetable crop store monitoring and management systems.

Proven environmental sensors provide ambient and crop temperatures information, ensuring cooling or ventilating fans are operated at the appropriate time.

The Relative humidity fan controller below is normally used for grain drying but we can provide this equipment with additional facilities like ambient and crop temperatures sensors. This allows the drying fan to be setup to cool grain.

 

Crop Monitoring Systems For Grain Potato & Vegetable Stores. Principle of operation.  The monitor is used to control a fan ventilating stored vegetables or potatoes. Up to four crop and one ambient electronic sensors monitor store temperature. When the ambient temperature is more than 2°C lower than the average of the crop temperature, the ventilating fan is switched on. Crop cooling will continue until the temperature of the stored crop has been reduced to the set minimum level. The fan will be prevented from running in frosty conditions. ..Store layout Grain Drying Fan Controllers with the option of extra facilities to cool grain. The controller is used to switch on crop store fans when ambient air is dry enough to remove moisture from the stored grain. Extra facilities like crop temperature sensors can be added to most models A range of replacement sensors for obsolete fan controllers are  available. It is often less expensive  and better to replace a sensor with a more modern device than have it cleaned and re-calibrated Price and details of crop drying and storage equipment.
