Fixed probes are appropriate for the structure of any type of silo. They provide ongoing, precise, reliable measurements of the grain temperature in the bins, for continuous regulation of the facilities.
STAM and Silostar are systems for reading the temperatures reported by the sensors. The two systems are compatible, allowing users to start out with a STAM (semi-automatic), then upgrade to a Silostar for complete temperature monitoring (readings, automatic alarms, and ventilation control).
These systems handle the exchange of data between the temperature probes and the readers. SERDIA offers two types of communication systems: wired or wireless.
SERDIA Silo Thermometry uses up to several thousand carefully-placed sensors to keep you continually informed of the temperature of stored grain.
Once a hot spot is identified, several actions may be triggered to eliminate it: an alarm (automatic), ventilation (automatic), and/or inter-bin transfer (manual).
The alarms can be customized, and ventilation can be automatically regulated according to outside temperature and grain temperature to minimize energy use and waste.
Grains have a natural tendency to breathe and germinate, transforming their energy reserves (starches, fats, etc.) into water, CO2 and heat.
- Loss of weight: Wheat kept at 30°C and 22% H2O loses 1.4% of its weight in a week. Corn waiting to be dried loses between 2 and 3% of its weight per day if the grain temperature rises to 50°C. Flour (starch) and oil (fat) yields decrease markedly.
- Loss of quality: browning of grains, loss of germinability, deterioration of nutritive value, acidification of fat content and, indirectly, the spread of molds and insects.
To limit this natural phenomenon and preserve quality, grains must be placed in "hibernation" by lowering their temperature and humidity in storage.
Storage Safety: Controlling the risk of fire and explosion:
The dangers inherent to the handling and storage of grains in silos are self-heating, fire and explosion:
- Self-heating is caused by the fermentation of grains that are stored too moist or too warm. If self-heating is not controlled, it can lead to fire.
- Fires happen when the following three factors are present: an ignition source, flammable material (grain and dust) and a combustion agent (oxygen in the air).
- Explosions occur when suspended dust or flammable gas (produced by anaerobic fermentation and self-heating) is ignited by an ignition source.
To avoid an explosion, simply remove one of the factors: the ignition source and/or the suspended dust. Serdia Silo Thermometry allows you to manage each of these risks.
