aeration fan

Catalogue: GRDC Updates
Aeration of stored grain has four main purposes - preventing mould, inhibiting insect development, maintaining seed viability and reducing grain moisture... Without circulation, the air surrounding the grain will reach a moisture (relative humidity) and temperature equilibrium within a few days... Aeration drying using large volumes of air can force a drying front through the grain in storage and slowly remove moisture...

Aeration uses fans and ducting to blow outside (ambient) air through grain... Running fans at the wrong time of the day or during unsuitable weather conditions can rapidly reheat or slowly rewet grain... During aeration drying, fans are designed to force much larger volumes of air through the grain bulk for much longer periods of time to ensure drying fronts are pushed quickly through...

GrAin fumiGATiOn - A Guide in order to kill grain pests at all stages of their life cycle (egg, larva, pupa, adult), phosphine gas needs to reach, and be maintained at, a concentration possible only in a gas-tight storage... The total time required for effective fumigation ranges from 10-17 days, accounting for the minimum exposure period, ventilation and withholding period... To control pests at all life stages and prevent insect resistance, phosphine gas concentration needs to reach 300 parts per million (ppm) for seven days (when grain is above 25 C) or 200ppm for 10 days (between 15-25 C)...

Treatment with Reldan and use of the fumigant ProFume ( Sulfuryl Fluoride ) are the main control measures currently used in central storages due to the difficulty of controlling this resistant strain with phosphine... Fans should be compared under the back pressure they are expected to work under when in use on a silo full of wheat, canola or other grains...
