DRYING

Q: What is drying?

A: Drying is the removal of excess water or moisture from grains.

 

Q: Why is drying important?

A: Drying inhibits pest infestation and fungal growth. In turn, this prevents the deterioration of grain quality.

 

Q: What is the GrainPro Collapsible Dryer Case™ (CDC™)?

A: The CDC™ is a low-cost solution for safe, effective and convenient drying of a vast range of agricultural commodities. It eliminates the need for fuel and electricity as it uses solar energy, which is the simplest and most economical drying method. Unlike other conventional drying methods, the CDC™ allows grain drying on almost any flat surface; it does not require a concrete or asphalt platform for installation. It also allows the drying of commodities right after threshing. In addition, it is easy to transport, maintain and repair. Its heavy-duty zipper makes it easy to close. GrainPro offers the CDC I™ and the CDC II™.

 

Q: What is the difference between the CDC I™ and the CDC II™?

A: The two differ in terms of material and wall type. The CDC I™ is made of black, heavy-duty reinforced polyvinyl chloride (PVC). It uses wooden pegs along the peg patch for its wall. The CDC II™ is made of woven coated polyethylene (PE). It has inflatable PE tubing for its wall.

 

Q: What are the available sizes for the CDC I™ and the CDC II™?

A: The CDC I™ and the CDC II™ come in the following capacities: 25 m2, 44 m2 and 75 m2.

 

Q: What commodities are not compatible with the CDC™?

A: None. The CDC I™ and the CDC II™ can be used for any sun-dried commodity.

 

Q: Do I need to fill the CDC™ entirely for it to work properly?

A: The CDC™ is designed to operate effectively when grains are dried under the recommended drying bed thickness. For paddy, maintaining a bed thickness not higher than 4 cm is a safe practice.

 

Q: During drying, how can I protect my commodity from anticipated rain?

A: In cases of anticipated rain or when drying will be continued the following day, move the grains to the lower side of the CDC™ (i.e., the side where there is no zipper cover). Use the upper side to cover the lower side by pulling the straps and close using the heavy-duty zipper.

 

Q: How often do I need to turn the grains during drying?

A: For optimum drying, turning the grains every 30 minutes is a safe practice.

 

Q: What tools can I use to turn the grains?

A: Wooden tools or accessories are recommended provided that they do not have sharp edges that may tear or puncture the liner.

 

Q: In case of damage, is CDC™ repairable?

A: Yes. For accidental tears or holes, use locally available packing tape. Cut a piece of tape that is big enough to cover the punctured area. Make sure that the patching tape has smooth edges (i.e., round corners) as sharp edges are prone to peeling off.

 

Q: Is the CDC™ reusable?

A: Yes.

 

Q: How should I store the CDC™ when it is not in use?

A: Clean the CDC™ after each use. Fold the CDC™ liner in such a way that the lifting straps are exposed. Keep the product in a place inaccessible to rodents.

 


HERMETIC STORAGE

Q: What is hermetic storage?

A: Hermetic storage, also known as airtight storage, is a pesticide-free alternative in protecting commodities against pest infestation and fungal growth. This technology is based on the principle of a modified atmosphere in a sealed container. The natural breathing process of grains, insects and fungi depletes the available oxygen and replaces it with carbon dioxide. The low-oxygen atmosphere kills pests and maintains the quality of the commodity.

 

Q: How do GrainPro storage products differ from other forms of storage?

A: GrainPro storage products, which are eco-friendly and cost effective compared to other forms of storage, can reduce storage losses to less than 1 percent annually without pesticide application. They can be installed with minimal infrastructure and within a few hours depending on the capacity. They also allow easy loading and unloading and have been tested under all climate conditions.

 

Q: What commodities can be stored in GrainPro storage products?

A: GrainPro storage products can safely carry a vast range of dry agricultural commodities (e.g., rice, corn, cocoa beans, coffee, barley and spices). Please note that GrainPro storage products are not recommended for storing fresh fruits, vegetables or medicine.

 

Q: How dry should a commodity be for it to be stored safely in GrainPro storage products?

A: GrainPro storage products work with commodities at or below the critical moisture content, which varies for each commodity. It is highly recommended to dry grains before storage. Please refer to the bulk density and moisture content guide for details, or contact GrainPro at This email address is being protected from spambots. You need JavaScript enabled to view it..

 

Q: What is moisture content and how do we measure it?

A: Moisture content (MC) is the amount of water present in the grain. It is usually expressed in percent. GrainPro offers a device called MM3 that is used to measure the MC of various commodities.

 

Q: If the commodity to be stored has already been infested by insects, should I fumigate it before storage?

A: No. The insects will die naturally in a matter of days when the commodity is stored in any GrainPro storage product.

 

Q: What storage products does GrainPro offer?

A: GrainPro offers the SuperGrainbag™, the GrainSafe™ and the Cocoon™.

 


SuperGrainbag™ (SGB™)

Q: What is the GrainPro SuperGrainbag™ (SGB™)?

A: The SGB™ is a bag made of multi-layered polyethylene (PE). Its water-resistant and gastight qualities help create a modified atmosphere. During the respiration process of grains, insects and fungi, the available oxygen is depleted and replaced with carbon dioxide. The low-oxygen atmosphere prolongs and preserves the germination capacity of stored seeds. GrainPro offers SGB™ IB, SGB™ III and SGB™ High Capacity (HC).

 

Q: What are the differences among SGB IB™, SGB III™ and SGB HC™?

A: The SGB IB™ and the SGB III™ differ only in their sealing method. The SGB IB™ is sealed with a set of cable ties while the SGB III™ is sealed with a dual groove ziplock and compatible slider. The SGB-HC™ is ideal for storing commodities in warehouses as semi bulk. Its liner comes with an outer bag made of polypropylene (PP).

 

Q: How many kilos of commodity can I store in the SGB™?

A: The SGB IB ™ and SGB III ™ come in 25 kg and 50 kg capacities that can be customized. The SGB HC ™ is available in 1 tonne capacity.

 

Q: Is it possible to use the SGB™ without an outer bag?

A: No. The SGB™ is used as an inner liner for ordinary PP or jute sack. The outer bag protects the SGB™ from rough handling and accidental tears.

 

Q: For the SGB IB™, what alternatives can be used for the cable ties?

A: Rope, rubber band or any knot can serve as alternatives. Make sure that the knot being used does not have sharp edges as these may damage the SGB™.

 

Q: Can the SGB™ be used outdoors?

A: The SGB™ is not for outdoor use because it is made of PE plastic, which is resistant to water but not to ultraviolet (UV) rays.

 

Q: How can I determine if the SGB™ is free from tears or holes?

A: The simplest way to examine the SGB™ is to inflate the bag and inspect for possible tears or holes.

 

Q: Is the SGB™ reusable?

A: Yes. The SGB™ can be used as long as the bag is in good condition.

 

Q: In case of damage, is the SGB™ repairable?

A: No.

Q: What is the difference between the GrainSafe II™ and GrainSafe III™?

A: The GrainSafe II ™, which is bulkstorage for commodities, can be set up on any elevated platform that allows unloading through the downspout located at the bottom. The GrainSafe III™, which is bagged storage for commodities, is usually set up on ground level such as concrete pavement or pallet.

 

Q: How many kilos of commodity can I store in the GrainSafe™?

A: The GrainSafe™ capacity is 1 tonne.

 

Q: Should the GrainSafe™ be installed indoors only?

A: No. The GrainSafe™ is designed for both indoor and outdoor installations.

 

Q: Is the GrainSafe™ reusable?

A: Yes.

 

Q: How should I store the GrainSafe™ when it is not in use?

A: Clean and dry the GrainSafe™ after each use. Fold the unit to a size that can fit in the carrying bag. Keep the product in place inaccessible to rodents.

 


Cocoon™

Q: What is the GrainPro Cocoon™?

A: The Cocoon™ is designed to protect dry agricultural commodities without the use of pesticides. By applying the principle of hermetic storage, it serves as a promising solution against pest infestation. It is made of made of white food-grade polyvinyl chloride (PVC), which makes it resistant to gas, water and ultraviolet (UV) rays.  GrainPro also offers Gas-Hermetic Fumigation  (GHF) Cocoon™ and MegaCocoon™.

 

Q: What is the GHF Cocoon™?

A: The GHF Cocoon™ has a built-in gas inlet welded at the bottom and an outlet cap at the top of the Cocoon™.  Carbon dioxide is flushed inside the Cocoon™ through the inlet port while oxygen is released through its outlet. It is an alternative to traditional chemical fumigation.

 

Q: What is the MegaCocoon™?

A: The MegaCocoon™ has the same material and technology as the basic Cocoon™.  It is used to store large volumes of bagged commodities.

 

Q: How many kilos of commodity can I store in a Cocoon™?

A: The Cocoon™ has the following capacities (based on wheat): 5 tonne, 10 tonne, 20 tonne, 50 tonne, 100 tonne, 150 tonne and 300 tonne. The MegaCocoon™ can carry 640 tonne and 1050 tonne.

 

Q: Can Cocoon™ be installed on bare ground?

A: In areas of high rodent activity, it is recommended to place the Cocoon™ on a concrete portion or on a layer of sand, ricehull and/or ricehull ash that is 5 cm thick.

 

Q: Should the Cocoon™ be installed indoors only?

A: No. The Cocoon™ is also designed for outdoor use, since the PVC material is resistant to ultraviolet (UV) rays and can withstand all types of climatic conditions. All types of Cocoon™ are supplied with GrainShade™ to reduce the temperature inside the storage unit when it is directly under the heat of the sun.

 

Q: How does the GrainShade™ work?

A: The GrainShade™ minimizes the heating effect of the sun by reflecting the sun’s solar rays up to 80 percent.

 

Q: How should the GrainShade™ be set up?

A: The GrainShade™ should be placed on top of the Cocoon™ with a clearance of at least 1 meter for proper ventilation.

 

Q: Can we store two or more different grains inside a Cocoon™?

A: Yes. Different grains can be stored in one storage unit provided they have the same moisture content.

 

Q: Do I need to fill The GrainPro Cocoon™ entirely for it to work?

A: No, as long as you completely pull up the slack at the bottom by means of the tension straps. However, it is recommended to fill the Cocoon™ with at least a three-quarter load to obtain full hermetic effect and full protection from pest infestation. Please take note that over capacity is better than under capacity.

 

Q: Can you add or withdraw commodity once the GrainPro Cocoon™ is filled and closed?

A: Yes. If the added items are infested, the insects will naturally modify the internal atmosphere and die eventually. However, it is not recommended to use the Cocoon™ for continuous in-out operations as the modified atmosphere will be disturbed. GrainPro recommends GrainSafe II™ for 1 tonne in-out of loose grain.

 

Q: Do I need to pump air out of the Cocoon™ or modify the air inside?

A: No. You do not need to pump out or change the atmosphere in any way. GrainPro storage products are hermetic; hence, the insects’ own natural metabolic functions use up the available oxygen and replace it with carbon dioxide. However, for commodities with high oil content like peanuts, it is advisable to flush carbon dioxide through the inlet valve. Do not wait for days to modify the gas concentration inside the system. GrainPro recommends GHF Cocoon™ and GHF GS III™.

 

Q: How will I know if the Cocoon™ is working?

A: The Cocoon™ is working when the oxygen level decreases as days pass.

 

Q: How fast is the drop in oxygen level after sealing?

A: Normally, if the stored commodity is sufficiently dried and heavily infested (except for coffee), the oxygen level can drop to 1-2 percent in 14 days. The drop in oxygen depends on the infestation level, moisture content, mold and other biological activity.

 

Q: What should I do when it is difficult to take oxygen readings?

A: First, check the flexible inlet valve if it is clogged or dirty. Clean the inlet to remove dirt and other impurities. Slightly flex the end of the inlet valve to create an opening for air to pass through. Refer to the Oxygen Analyzer Manual for further information.

 

Q: What should be done if the oxygen level starts going up?

A: If the oxygen level starts going up or does not drop in a span of seven days, examine the entire length of the zipper and search for possible openings. Inspect the top, bottom and all the sections for holes and tears. For assistance, contact GrainPro at This email address is being protected from spambots. You need JavaScript enabled to view it..

 

Q: Can rodents chew right through the PVC material when the Cocoon™ is erect?

A: Yes, but only if the sides have not been tightened sufficiently. Rodents can penetrate the smooth, slippery surface of a Cocoon™ if the sides have limited tension or by jumping down from an overhang, such as a low-hanging branch of a tree. In areas of heavy soils and with high rodent activity, it is recommended to install a Cocoon™ on a layer of ricehull, sand, gravel or ash that is 5 cm thick. However, concrete or paved flooring is the best option.

 

Q: In case of damage, is the Cocoon™ repairable?

A: Yes. Use the patching material and adhesive found in the repair kit included in the package.

 

Q: How can I patch a Cocoon™?

A: To patch a Cocoon™, simply follow this procedure: (1) clean the area to be patched using a damp cloth; (2) cut a patching material 1 inch larger than the hole or tear; (3) make sure that the edges are round to avoid peeling off; (4) make sure that the surface is clean before applying adhesive both to the area being patched and the patching material; (5) wait about 10 minutes until the adhesive has become sticky; and (6) apply the patch and press into place.

 

Q: I ran out of silicon spray, adhesive and PVC patch. Where can I buy new products?

A: These items are locally available in any hardware. WD-40 is a good replacement for the silicon spray. Contact cement is an alternative adhesive and binds PVC well.

 

Q: Is the Cocoon™ reusable?

A: Yes.

 

Q: How should I store the Cocoon™ when it is not in use?

A: Clean the Cocoon™ after each use and let it dry. Fold the unit to size that can fit in the carrying bag. Keep the product in a place inaccessible to rodents.

 

Q: How should I clean the Cocoon™?

A: Use water and ordinary soap to clean.

 

Q: What is the expected life span of a Cocoon™?

A: The Cocoon™ has a lifespan of at least 10 years when used outdoors.

 


Accessories

Oxygen Analyzer

Q: What is the oxygen analyzer?

A: The oxygen analyzer is a device that enables the monitoring of the oxygen level inside hermetic storage units.

 

Q: How can I activate the oxygen analyzer?

A: Activate the instrument by turning the OFF-ON/CAL. knob clockwise. The sensor is on when the green LED is lit. To start sampling, connect the hand pump to the inlet by inserting the tube from the white connector of the hand pump into the metal quick connector IN. The black connector in the hand pump indicates the suction side. It is extremely important to pump clean air into the analyzer and to calibrate before measuring concentrations.

 

Q: Why is it important to calibrate?

A: Failure to calibrate will produce distorted readings. .

 

Q: How is calibration done?

A: To calibrate, pump clean air into the monitor inlet and adjust the knob clockwise to its maximum. Continue pumping while turning the knob—this time, counterclockwise—until the display shows 20.9. The instrument is then ready for sampling.

 

Q: How do I operate the instrument to start sampling?

A: Insert the suction side of the analyzer tube into the gas sampling port of the storage structure. Continuously pump air into the analyzer to measure the oxygen level inside the storage structure. Press and hold the hand pump so that the lowest possible reading will appear in the display.

 

Q: During oxygen reading, the hand pump remains deflated. Why does this happen?

A: There are some possible reasons. The tube may not be connected properly or the hand pump tube and/or the flexible inlet valve of the Cocoon™ are clogged. Make sure to insert the white connector of the hand pump into the metal quick connector IN,  remove the dirt from the tube, and clean the inlet valve.

 

Q: When should I replace the sensor of an oxygen analyzer?

A: The sensor has a maximum life of one year and should thus be replaced on or after the 12th month. When the sensor degrades, it produces erratic readings. For sensor replacement, please contact GrainPro at This email address is being protected from spambots. You need JavaScript enabled to view it..

 

Q: When should I replace the battery?

A: Replace the battery when the battery status is empty or low. When this happens, the LCD screen shows LOW BAT.

 


Oxygen Absorber

Q: What is the oxygen absorber?

A: The oxygen absorber is a small packet that contains iron powder. The packet is made of a material that allows oxygen and moisture to enter but does not allow the iron powder to leak out. The oxygen absorber is safe to place on top of food; it will not contaminate the food as it comes in a sealed pouch.

 

Q: How does the oxygen absorber work?

A: The oxygen absorber performs its action through a chemical reaction. The iron powder reacts with the oxygen in the air causing the iron powder to rust. When all the iron powder has oxidized, the oxygen absorber is loaded and the absorbing action stops.

 

Q: When can I activate the oxygen absorber?

A: The oxygen absorber is activated automatically when it comes in contact with air. It keeps absorbing oxygen until the saturation point is reached.

 

Q: For what commodities can I use the oxygen absorber?

A: The oxygen absorber is recommended for dry agricultural grains and highly recommended for oily commodities like peanuts.

 

Q: How many oxygen absorbers should I use?

A: One sachet of GrainPro Oxygen Absorber can be used for at most 50 kg of grains. Make sure to press down the grains to remove excess air before sealing the bag.

 

Q: How will I know that an oxygen absorber is working?

A: The most obvious sign that an oxygen absorber is working is when it becomes warm.

 

Q: Is the oxygen absorber reusable?

A: No.

 


Rodent Guards

Q: What is the rodent guard?

A: The rodent guard is an inverted funnel-shaped plastic that restricts the pathway of rodents. It is made of smooth plastic resistant to ultraviolet (UV) rays. One set contains four pieces.

 

Q: Are rodent guards included in GrainPro product packages?

A: Rodent guards can be purchased separately but are included in the GrainSafes™ and the Cocoons™ packages.

 

Q: How do I install rodent guards?

A: One set of rodent guards can be installed on any platform legs with round or square leg perimeter of 22 cm (9 in) to 44 cm (17 in). Please refer to the Rodent Guard User Guide for complete installation procedure.
