Grain growers and handlers use aeration for a range of quality-related reasons.
Most importantly, they use aeration to lower temperature and moisture levels, which helps preserve seed germination and control insect activity.
Aeration helps protect the quality of stored grain by passing controlled amounts of air through storages.
It stabilises temperature and moisture levels, prevents localised temperature increases or "hot spots" and discourages moisture migration.
Providing too much air can be as harmful as too little, so the team at Customvac assess a customer's operation and determine the best match to their needs.
Controlled aeration lowers the temperature of the grain bulk during long-term storage, reducing insect activity dramatically.
To satisfy certain market standards an additional step of fumigation in a sealable storage may be needed to ensure totally insect-free grain at delivery.
A combination of aeration and dryacide blanketing is also effective in protecting grain against insects without leaving chemical residues.
To get the best value for money, aeration systems must include the correct fan size for the operation and the correct style and size ducting for the product being stored.
An automatic controller is a valuable addition that will take the guesswork out of operating the aeration system, particularly for long term storage of grain.
A controller will automatically select the coolest available air and correct operating times ... high performance with less operator input.
The cost of an automatic controller is outweighed by the lower risk of grain losses.
One unit can control up to 24 storages.
Automatic controllers add little to the initial cost per tonne of storage but quickly pay for themselves through better grain quality.
Customvac Australia was started in 1983 by Jim Sampson and his wife, Bonnie Hymers, following a trip to an agricultural trade show in Canada.
The company initially marketed a range of pneumatic grain and feed handling equipment within Australia.
Since then, the company has expanded its market to include grain management equipment with an international client base.
