HGCA Grain Storage Guide 3rd Edition is released

The HGCA has now released its most recent edition of their go to guide for grain storage. The Grain Storage Guide for Cereals and Oilseeds is an invaluable resource when considering grain drying and storage options.

Safe, effective grain storage is key to assuring crop quality and helping prevent loss of premiums through claims and rejections.

The economic benefits of storage are clear. The capability of storing grain for a November delivery will attract a £4/tonne premium over the harvest price, with May movement giving a further £7/tonne. Understanding the costs of storage is crucial. Grain drying is key factor in effective storage and the best practise guidance laid out in this booklet is endorsed by DEFRA, the NFU and FERA among others.

HGCA’s Grain storage guide was first published in 1999 and has become a key reference for most assurance schemes. This third edition of HGCA’s grain storage guide combines information from the previous edition and the results of a five-year Defra and industry-funded LINK research project in a new risk management approach to grain storage based on HACCP (hazrd analysis and critical control point) principles.

The guide recognises that achieving target moisture content within the shortest time possible is necessary to prevent the risk of mycotoxin formation and quality degradation. It looks are the various ways that this can be achieved. The full document can be downloaded here.

ADAS Harvest Report 2010 – a bit wetter and a bit longer than normal

The final cereals in Scotland were harvested this weekend after some terrible weather in the past three weeks. I spoke to one Mecmar owner at the end of last week who claimed to be now ”catching it dry at a little over 25% moisture”. There are very few place in the UK where a grain drier works harder than in Aberdeenshire. With harvest now at a close we can see how we have all got in the ADAS Harvest Report 2010.

It was published 30th September when the majority of harvesting was completed. In summary it concludes: Continue reading ‘ADAS Harvest Report 2010 – a bit wetter and a bit longer than normal’

Mecmar batch grain drier productivity and performance

Nearly the entire UK area has now been harvested. The last 5% of wheat and 10% of spring barley have now, more than likely been cleared up since the most recent ADAS Harvest Report was published last Thursday. Mecmar grain driers are now hard at work around the UK with most farms getting well into the seasons drying work. At this point of the year the machine will be generally operating at its peak efficiency and maximum throughput will be achieved.

With this in mind, it seems like a good time to examine the variables that affect the productivity of a recirculating batch grain drier like the Mecmar. This post will focus on the key variables in terms of crop properties and condition that will impact the productivity of a mobile grain drier: Continue reading ‘Mecmar batch grain drier productivity and performance’

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’

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’
