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.

1.3. COMMENTS, COMPLAINTS, AND/OR CLARIFICATIONS:

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:
