Quickly calculating grain shrinkage

When grain is accepted by merchants at a moisture content level which is higher than that contracted, the weight loss due to drying must be calculated. This enables the actual value of the grain to be worked out. This charge and also the charge applied for then drying the grain can be avoided through having suitable facilities for on-farm grain drying.

The loss in weight during drying is known as water shrinkage and occurs when grain is dried, whether in the field or mechanically. The weight of dried grain may be calculated, by using Continue reading ‘Quickly calculating grain shrinkage’

The harvest rush on second hand mobile batch grain driers

Harvest 2010 is looking a bit gloomy at the moment, the weather forecast continues to look unpromising and 75% of UK wheat is still standing in the fields. However, the prospect that wheat prices may remain bullish in the short term is a welcome distraction (especially if Ukraine impose export quotas this week). Unfavourable weather conditions do not only cause panic buying on the international wheat market but they also cause panic buying on the (slightly smaller but no less important) UK second hand grain drier market.

This combination of dreary weather forecasts and crops standing in the field drive hurried enquiries for second hand grain driers, the sole criteria being Continue reading ‘The harvest rush on second hand mobile batch grain driers’

Mobile batch grain driers and grain moisture testing

This time of year we are always occupied with helping new customers to get the best from their Mecmar grain driers and usually reminding a few older ones what they should be doing too. A great many questions centre around the issue of drying temperatures. Setting the air temperature is a straightforward business but the process by which you relate the cereal temperature to the moisture content (mc) of a crop can be trickier.

One of the main pitfalls is the accurate measurement of crop moisture straight from the drier. HGCA research shows that moisture content variability is increased when measuring freshly harvested grain, even within well mixed samples. The research went on to find that poor operator practise could result in errors of Continue reading ‘Mobile batch grain driers and grain moisture testing’
