The rice dryer has a high moisture content after harvesting. If you want the rice to meet the conditions for safe storage (not moldy), you must reduce the moisture content of the rice to a safe moisture content for storage (i.e. 12% is the safe level for rice storage). moisture), used to reduce moisture content.

According to the relative movement direction of grain and air flow, dryers can be divided into cross flow, mixed flow, forward flow, counter flow and forward and reverse flow, mixed and counter flow, forward mixed flow and other types. Today, let’s introduce the downflow dryer in detail.

Grain downstream dryers are mostly tower-type structures that combine a funnel-type air inlet duct and an angular box exhaust duct. It is different from a mixed-flow dryer that uses one main air duct to supply hot air, but consists of multiple (stages) ) The hot air duct supplies different or partially the same hot air. The number of domestic manufacturers is less than that of mixed flow dryer manufacturers.

The advantages of Dingli corn dryer are:

⑴The hot air temperature used is high, and the temperature in the high temperature section can generally reach 150~250℃;

⑵The unit heat consumption is low, which can ensure the quality of the grain after drying;

⑶ Dryers with three-stage downstream flow and above have the advantage of reducing large amounts of water and can achieve higher productivity;

⑷ During continuous drying, the precipitation range is large, generally up to 10% to 15%;

⑸Suitable for drying food crops and seeds with large moisture content.
