Why are legumes<\/strong> considered high<\/strong> energy<\/strong> foods<\/strong>? Because they consist of 50% starch<\/strong>, an important carbohydrate. However, despite the high nutritional value typical of legumes, they are also known to contain antinutritional factors: antitriptics. The presence of these reduces the bioavailability of various components, thus lowering the digestibility of proteins<\/strong> and the absorptionof<\/strong> minerals<\/strong> naturally present in legumes.<\/p>\n

How can these antinutritional factors<\/strong> be removed<\/strong> from freshly harvested legumes? There are several methods<\/strong>, such as cooking<\/strong>, roasting<\/strong> or extrusion<\/strong>. All of these bring the grains to sufficiently high temperatures to transform the antinutritional factors and break down their effectiveness.<\/p>\n

The cereal roasting<\/strong> phase – following the drying phase – is the process that allows these elements to be definitively neutralised<\/strong>. If drying<\/strong> enables every farmer to secure his harvest<\/strong>, roasting<\/strong> improves the quality<\/strong> of the grain<\/strong>, increasing its palatability and taste.<\/p>\n

To find out in detail how Mecmar’s dryers and roasters work<\/strong>, and to discover how these plants eliminate antinutritional factors from legumes, continue reading!<\/p>\n

Curb the aflatoxin problem with Mecmar solutions<\/h3>\n

Aflatoxins<\/strong> are one of the most dangerous categories of mycotoxins for your livestock<\/strong>. If ingested through feed, they can compromise the health<\/strong> of animals and the quality<\/strong> of food products derived from them. Therefore, in order to avoid this, it is essential to dry and storage cereals<\/strong><\/a> immediately after harvesting.<\/p>\n

During the drying process, excess water that impregnates the grain is expelled from the grain<\/strong>. Once this stage is complete, the grain will leave the mobile<\/a> or tower dryer<\/a> dry and clean, with a moisture content of no more than 13-15%<\/strong>, thus ensuring maximum safety during storage.<\/p>\n

If the slow drying process<\/strong> removes toxins (carcinogenic elements) from the grain, thus preventing contamination of the grains<\/strong>, it is then finally possible to move on to the roasting<\/strong> stage. It is through this that the grain is heated to a temperature of 110 \u00b0C<\/strong>. This results in a cereal with a crunchier texture<\/strong>, which is therefore more appreciated by both humans and animals.<\/p>\n

Did you know that with Mecmar’s range of electric roasting<\/a> machines you can roast and cool the grain in the same plant<\/strong>? The output<\/strong> product<\/strong> is roasted<\/strong> (antinutritional factors are completely eliminated) and<\/strong> already<\/strong> cooled<\/strong> to a temperature set at 20\u00b0C, ready for storage or further processing.<\/p>\n

A wholesome meal for your farm: remove the antinutritional factor from soya<\/h3>\n

The high nutritional value of soya – due to the presence of oils and derived proteins – makes this seed<\/strong> particularly valuable<\/strong>. In order to effectively process the soya bean immediately after its harvest, it is freed<\/strong> from all those antinutritional factors that can compromise its quality<\/strong>.<\/p>\n

An example of an antinutritional factor contained within soya is the enzyme urease<\/strong>. How to remove it effectively? Through roasting! Through this process, the antinutritional components<\/strong> are reduced<\/strong>, while the best nutrients<\/strong> and fats<\/strong> are maintained at stable levels.<\/p>\n

Mecmar<\/strong> roasters<\/strong> also allow the soya bean to remain intact<\/strong>. In this way, less soya is needed to obtain the same calories in the diet of the animal to be fed.<\/p>\n

Which roaster model should you choose to remove the antinutritional factor from your cereals?<\/h3>\n

All Mecmar<\/strong> roasting machines<\/strong> ensure uniform treatment of all types of grain<\/strong>. Speed<\/strong> and safety<\/strong> are two distinctive traits that characterise Mecmar’s grain roasting plants. But specifically which path does the grain<\/strong> follow inside the plant?<\/p>\n

The grains enter\u00a0<\/strong>the roasting machine still at room temperature\u00a0<\/strong>(approximately 20\u00b0C) and then encounter a flow of hot air, which, by heating the grains, makes it possible to obtain a perfectly homogenous roasting process<\/strong>, without the risk of damaging the treated grain.<\/p>\n

Depending on the type of animal (cattle, pigs, poultry), size and number to be fed Mecmar has the right roaster for you: there are 5 models of roasting machines<\/strong> you can choose from. The T5<\/strong> and<\/strong> T10<\/strong> versions<\/strong> are suitable for small to medium-sized farms<\/strong>, while the T20<\/strong>, T50<\/strong> and<\/strong> T100<\/strong> models are ideal for medium to large farms<\/strong>, as they can roast up to 6 tonnes of product per hour.<\/p>\n

Diesel or electric grain roaster? Which one should you choose?<\/strong> We discuss this in our article dedicated to the Mecmar electric cereal roaster<\/a>.<\/p>\n

Choosing Mecmar machines with the aim of eliminating the most harmful antinutritional factors from cereals means relying on some of the most innovative roasting solutions<\/strong>. The maximum efficiency of these roasting machines is guaranteed by their compact design\u00a0<\/strong>and the fact that the equipment is mounted on a mobile frame<\/strong>, which allows the machine to be easily positioned as required.<\/p>\n

In conclusion<\/h3>\n

In this article, we have looked at the main aspects that characterise Mecmar dryers<\/strong> and<\/strong>, above all, roasters<\/strong>. It is precisely the latter that represent the solution that will allow you to remove the antinutritional factors present in legumes after the harvesting and drying phase<\/strong>. Although this is the main reason why more and more farmers are choosing Mecmar equipment, it is not the only reason why it is important to roast cereals<\/strong>:<\/p>\n
