Build my Feedmill: Grain drying

by John Bowes, International Sales Director, Sukup Manufacturing Company

On March 13th at VIV Asia in Bangkok, Milling and Grain, in conjunction with VIV Asia, held the Build my Feedmill Conference for feed industry professionals, academics and businesspersons to discover more about the inner workings of a feed mill.

For two-hours, our 12 speakers gave presentations about their own unique products that assist with the inner workings of the feed mill, and carried us through the entire milling process, from intake and conveying to weighing, grinding, pelleting, drying and cooling, through to automation.
 


This article is the second in the series that will allow our readers to discover more about the inner workings of a feed mill, directly from our Build my Feedmill Conference speakers.

Crops store best if they are cool, dry, and clean. Mould growth is dependent on both temperature and crop moisture content. Crops that contain considerable foreign material or broken kernels will be more susceptible to mould and insects, so it is important that crops are cleaned to reduce this hazard or dried to between one and two percent lower moisture content than clean crops.

Checking grain
All stored grain needs to be checked on a regular basis. Check stored grain bi-weekly during critical fall and spring months when outside air temperatures are changing rapidly. Check at least once a month during winter, but more often if there are problems.

Search for small changes that are indicators of potential problems, such as crusting or condensation on your bin roof. It may also be necessary to check the moisture of grain with a moisture meter. Any increase in temperature indicates a problem, unless outdoor temperatures are warmer than the crop.

Check and record temperatures at several points in your grain bin. Testing the weight of your crops is another evaluation to ensure it is at its best quality and in peak condition.

Filling and coring the bin
Best storage results are obtained when crops are level in the bin (See Figure One). Lowering the centre core of stored crops improve airflow and make checking the crop easier. Levelling can be done with a grain spreader or by withdrawing grain from the centre after filling.

In most bins, normal grain discharge flow creates a centre core that flows directly down to the unload conveyor or unload spout. This creates an inverted cone in the surface grain that gradually increases in diameter. As unload continues, grain funnels down the centre core and to the conveyor or unload spout.
