MECMAR: GRAIN DRYERS SPECIALISTS SINCE 1958

Mecmar’s product range includes the following types of products: mobile dryers (with capacities ranging from 7 to 75 tons), tower dry ers for large-scale drying plants, roasters for soy and other cereals, electric roasters for soy and other cereals, cogeneration biological dryers and special systems for drying a wide variety of products.

When considering the purchase of a grain dryer (whether new or used), Mecmar recommends that you do not limit yourself to a comparison of the capacity (in tons) of the various mobile dryer models on the market. In fact, it is also advisable to compare the hourly productivity (ton/h) of the different dryers. Dryers of different brands also have different hourly productivity, even though they have the same capacity at standstill. The hourly productivity, therefore, provides a common parameter for comparing dryers and is also a clear indicator of the machine’s performance during operation.

If a dryer looks good, it is already more likely to have been kept in good service and maintenance condition. In any case, more specific components to check are:

• Control panel and burner. Check for water seepage, rust, and possible modifications that may have been made on site. Are all the machine components original? Regardless of the age of the dryer, the control panel and burner should always remain in good condition.
• Center tube and augers. Inspect the center tube along its entire length, looking for areas that may have holes or old repairs. Also inspect the auger coil reinforcements-the thickness indicates how much longer they can last before needing to be replaced.
• Mechanical transmission components. The best indicator of the condition of the gearbox, which moves the center auger, is the oil in it. Check the belts and that the mixer is aligned correctly.
