Grain dryers
Diagram of airflow through a silo
Grain dryers and aerator to fit exisiting slios; elevated, flat bottom and sheds.
Air introduced under plenum fitted horizontally across the bottom of the silo.
When silo is full, underneath the plenum is open airspace.
The air is forced down then up the cone to the walls for even distribution through the silo.
The same plenum suitable for all cone bottom silos. 3m (10 ft) diameter to 9m (30ft).

I have been in the silo sealing trade for 18 years now and I reckon this is the best dryer/aerator ever introduced into the on farm storage market. No other aerator in the market can dry grain! They can cool and even out moisture between a dry load an a moist one in a silo, but cannot dry grain. The system has been tested and been in use by farmers for 5 years now.
I cover a large slice of the grain growing area in the Eastern states, from Ceduna, South Australia, to Toowoomba, Queensland. This is the best machine I have ever come across. The only dryer that comes close is a Kotzur drying silo, which start at $9000 each.
Powered by a 3hp electric motor or 5.5hp Honda ($400 extra); the air is blown in by a huge fan (see photo on brochure) through 150mm (6") ducting into the silo. Then distributed by a device called a plenum; which is an open upside down V, 2.4mtr (8 feet) long and 300mm (1 foot) across at the open side. It is fixed across the centre of the silo cone and attached to each side. (see attached diagram of the air flow). There are no holes in the 'v' so it can be used to dry all seed types; canola, lentils, grains etc.
When drying stored grain we use ambient air and pump it through the grain and it dries surprisingly quickly during the warmer periods of the day (depending on weather conditions).
It they can get it off and into the silo and then dry it they will get much better returns. Wheat and barley were generÂally harvested at 12 to 13 percent moisture, our system allows stripping at 16 to 17 percent. Our system works the same as an evaporative air conditioner although in this case the grain is the wet filter.
To cool stored grain the fan should operated during the coldest periods of the night to achieve maximum cooling performance. An automatic controller is available to select only the coldest conditions when
cooling and the warmest conditions when drying.
Air runs through ducts from a fan to the base of the silo and flows upward through grain, taking moisture and heat with it.
It does depend on how big the silo is, but a normal system would operate on two silos at once.
Automatic Temperature/ Humidity Controller:
Allows you to set humidity and temperature for drying grain in the best climatic conditions. Then reset the dials for aeration to blow cold, dry air through the grain. The most inexpensive controller on the market and the only one with humidity and temperature all in one. Take the guesswork out of grain drying and you can get on to other jobs while the fans are monitored by the controller. The unit is fully portable and only the size of a shoebox.
