Drying is a millenary technique that has always represented a competitive advantage<\/strong> of great value within farms. Today on the market there are different models, but what are the criteria<\/strong> to take into consideration to choose the type of dryer that is best for you?<\/p>\n

Every agricultural business<\/strong>, whether small or large, can enjoy an enormous benefit<\/strong> from the use of a drying system: increasing productivity by spending the minimum.<\/p>\n

In this article, Mecmar<\/strong> wants to suggest the three most useful tips<\/strong> to guide you in choosing the best grain dryer for your business.<\/p>\n

# 1. Evaluate your company’s drying needs<\/h3>\n

To choose the most suitable type of dryers, it is essential to understand what kind of functionality<\/strong> your company needs: what type of cereal do you need to dry and how much for each season? How will the product be treated after drying (human, animal, seed …)?<\/p>\n

Each dryer has different drying capacities<\/strong>, which mainly depend on the size of the dryer<\/strong>. To always be able to obtain the best results, you need to have the most valid devices, which thanks to their capabilities will allow you to achieve the best results.<\/p>\n

In general, the rule that applies is the following: the greater the size of the dryer, the higher the level of hourly productivity<\/strong> obtained by the dryer will be. Generally, for low hourly productions a mobile dryer is better, while for important productions it is better to consider a continuous cycle dryer.<\/p>\n

To obtain a truly effective drying<\/strong>, it is necessary to define the correct drying temperature<\/strong>, which varies according to the type of cereal, bearing in mind that each cereal can withstand a maximum level of heat<\/strong> above which there is a risk of spoiling the nutritional principles<\/strong> of the harvested cereal.<\/p>\n

#2. Choose the type of drive<\/h3>\n

Grain dryers<\/strong> can be operated electrically or by tractor. This affects purchase costs and consumption costs. A tractor dryer<\/strong> can be moved and used anywhere, while an electrically operated dryer<\/strong> requires a constant and stable supply of electricity, suitable to support the dryer loads. An electric drive allows to include automation and independent management of the drying process.<\/p>\n

There are also dual drive dryers<\/strong> that, depending on the needs, can be operated by electricity or by tractor.<\/p>\n

#3. Consider several forms of warming<\/h3>\n

According to the needs, there are two main and different forms of heating<\/strong>: indirect or direct. In the case of direct heating<\/strong>, the combustion products are mixed with high volumes of clean air before coming into contact with the cereal to be dried. In the case of indirect heating<\/strong>, however, the products of combustion are physically detached from the products of combustion. Also in this case, the system and consumption costs are different.<\/p>\n

These costs have to be compared with the purchase costs of the various heating systems: for example, diesel, which seems the least convenient system from a consumption point of view, may be the heating system that costs less as well as the easiest to manage in logistical terms.<\/p>\n
