GrainPro®
Bubble Dryer™
Keeping contaminants away to safely and evenly dry commodities even in erratic weather conditions.
The GrainPro® Bubble Dryer™ is a tunnel-type dryer designed to dry agricultural commodities while protecting them against sudden rains and unpredictable weather. Using heated air, the commodities’ moisture content is vaporized and pushed out by ventilators through an exhaust port.
Using this solution, commodities can be dried at an average rate of 0.5% moisture content per hour (based on paddy and corn). However, with optimal conditions of high atmospheric temperatures, drying time is about 6 to 8 hours at a moisture content of 22% to 14%.

FEATURES
Faster drying time during fully sunny conditions over conventional sun drying
Installable on any flat surface, a multi-commodity dryer
Portable and easy to relocate
A cheaper option/solution relative to existing mechanical dryers
Protects commodities during drying to prevent post-harvest losses
Also provides protection from birds, fowls, and other animals
Prevents spillage & contamination with hazardous materials
The GrainPro® Bubble Dryer™ comes in two different model types:
(A) a solar model, operating solely through renewable solar energy, and
(B) an electric model that uses electric power from the grid. Both model types are provided with a rake mixer that can be used in all terrain and a tube mixer (optional mixing device) which provide undulating motion during the mixing operation.

ADD-ONS

Bubble Dryer Bed ™
This portable, inflatable dryer bed works perfectly with the GrainPro® Bubble Dryer™. It allows high-moisture commodities to be dried at a faster rate. This is possible through the additional airflow created due to the elevated bottom of the bed. It is made of UV-resistant PE mesh supported by pressurized PU tubes.

.. in addition to protecting the grains from animals, insects, contamination, and rain, the dryer also prevents losses due to spillage or cars running over the grains, which are traditionally spread to dry on roads.
