1. INTRODUCTION
The GrainPro® Solar Bubble Dryer™ 50 (SBD50) is a collapsible,tunnel-type dryer with 1.0 metric ton
(1,000kg) drying capacity designed to protect the agricultural commodity from intermittent/sudden rains
during drying, and to prevent spillage and contamination. Drying performance is dependent on the solar
radiation, relative humidity of the ambient air, and moisture content of concerned agricultural
commodity. The SBD50 consist of a transparent cover made of UV-resistant polyethylene film connected
to the black reinforced PVC drying floor by a heavy-duty zipper. Through the transparent top cover, solar
radiation enters the drying chamber and heats up the agricultural commodity being dried. Moisture
content is then vaporized and pushed by the ventilators out from the drying chamber.
The SBD50 technology makes drying possible even during unpredictable weather conditions. It can dry
grains and seeds at an average drying rate of 0.5% per hour based on paddy and corn. However, during
full sunny conditions drying time is about 6 to 8 hours on a moisture content of 22% to 14%. It is a multi-
crop dryer that can be used to dry paddy, corn, coffee, and others.
There are two GrainPro SBD50 commercial models, namely: SBD50-Solar which operates purely on solar
energy to dry the commodity and run the ventilators. While the SBD50-Electric uses electric power from
the grid to run the ventilators and solar energy to dry the commodity. There is a rake mixer that can be
used in all terrain and a tube mixer (optional mixing device) which provides undulating motion during
mixing operation.
1.1. FEATURES:
1.1.1. Collapsible dryer can be installed on any flat surface, a multi-commodity dryer.
1.1.2. Protects the commodity being dried from sudden rains, spillage, and contamination.
1.1.3. Protects the commodity from fowls, birds, and other animals.
1.1.4. Protects the commodity from unhealthy and hazardous contaminants.
1.1.5. Designed to address the effect of climate change.
1.1.6. The SBD50-Solar doesn’t use fossil fuel that contributes to greenhouse gases.
1.2. PRODUCT GUARANTEE:
1.2.1. In accordance with the terms and conditions herewith, GrainPro, Inc. fully guarantees the quality of this
product provided it is used according to the instructions in this manual.
1.2.2. Please read and understand the manual thoroughly before using the Solar Bubble Dryer50.

5. ASSEMBLY AND OPERATING PROCEDURES
5.1. SITE SELECTION
5.1.1. In selecting the site, look for:
a. A level ground away from standing or
running water.
b. Open area for maximum absorption of
solar radiation.
5.1.2. Preparing the selected site (about 4m x 30m) by:
a. Clear away all sharp and/or pointed objects (stones, broken glass, nail, etc.) which might puncture
the SBD50 drying floor. In addition, refrain from smoking while working because hot ashes may
damage the SBD50 materials.
b. Make sure there is sufficient space around the SBD50 for pulling the “Tube Mixer”on both sides of
the dryer.
c. The positioning of the SBD50 and solar panel should be on a location where maximum exposure to
solar radiation can be obtained.
5.2. INSTALLATION
5.2.1. Set-up/installation:
a. Unfold the SBD50. Take note of the folding
pattern while it is being unfolded. This
unfolding sequence should be followed in
reverse when preparing for proper
storage.
b. Pull the other end to get rid of the folds
before laying to the ground. Make sure
that the drying floor is properly stretched
at two meters wide (for the drying area)
along the full length of the SBD50. This will
ensure that the drying floor will stay flat
when using the “Tube mixer”.
5.2.2. Ventilator and supporting structures:
