Indoor grain silos are structures used for storing agricultural products such as grains, seeds, nuts, coffee, and beans. They are large container-like structures with a robust build to keep the materials safe and protected. Here are some of the most widely used types of indoor grain silos:
Bin or Vertical Steel Silo
Indoor grain bin silos have a cylindrical shaped structure and a flat bottom that makes them 30 to 90 feet tall. The walls of these steel grain bins are constructed with galvanized steel sheets. Of the available options, galvanized steel sheets are the most resilient and longest-lasting materials. Indoor grain bin silos are also constructed with wall inserts, which act as a supplemental internal support system and provide extraordinary insulation.
Concrete Towers or Bunkers
Usually, tall, vertical concrete towers function similarly to grain bins but on a much larger scale. Concrete bunkers resemble large boxes with concrete walls. Also, both of them have the capacity to hold great volumes of grains and are primarily used for industrial-level storage.
Flexible Fabric Silos
Fabric silos are made of heavy-duty fabric and can be collapsed for transportation or expanded for use. In addition, these silos are easy to install and offer a cost-effective storage solution for indoor grain storage in comparison to other options.
Hybrid Silos
They combine materials, such as concrete and steel, to optimize the benefits of indoor grain storage. For instance, a hybrid silo might have a concrete base for stability and steel for corrosion resistance.
Adjusted Silo
It combines traditional silo design with modern technology, like aeration systems and monitoring equipment, to improve grain quality and facilitate better management of the stored produce.
Jumbo Bagfor Granar
A jumbo grain bag is a sizable, flexible bag designed for the storage of grains and other agricultural products. It is produced from durable, UV-treated polyethylene material and comes in various sizes, usually with a capacity of up to 2 tons to 3 tons per bag.
Indoor silos for grains come in various sizes and shapes to fit specific needs. They're usually made of strong metals or plastics that won't let moisture in. The doors and feeding/storage pipes are very secure, so animals can't get in or out. Usually, the silos can be about 1 meter wide up to 10 meters, and they stand tall, even up to 6 meters or more, because the more vertical space there is, the more grains can be stored indoors. There are special gadgets inside like augers, pneumatic pumps, or conveyors that save time and energy by automatically moving the grains. Silos also come equipped with temperature sensors and humidity monitors that can be checked online through a smartphone or other gadget, letting people know if the grains are still good or not. Furthermore, indoor grain silos can be fitted with anti-insect and anti-weevil fumigation systems. An optional dust collection system can also be fitted to remove any residues from grains or legumes stored inside the silo. The structure itself is made of food-safe materials, and all parts are easy to clean to prevent any cross-contamination. What's more, some modern silos include RFID technology so that farmers and grain merchants can have a foolproof inventory, thereby, simplifying grain tracking from point to storage, point, and even the delivery point.
Indoor grain silos need regular checks, cleaning, and repairs to keep them in good shape and their grains safe. Inspection should be done monthly by looking for signs of corrosion, rust, or damage, especially on the walls and ceilings. The grain bin can be vacuum cleaned to remove leftover debris, or a cleaning brush can be used to get rid of dirt. When making repairs, the same dirt- or debris removal technique can be used to make for a long-lasting repair. Grains must not be allowed to pile on the floor, thereby, reducing the space on the floor that can be cleaned up. Indoor grain silos should be painted regularly to protect the metal surface from rusting. Only non-toxic paints should be used, and all the paint should be allowed to dry up before any grain is stored in the silo. Silos with insect fumigation systems should be inspected regularly too, so the grains can be protected. Moreover, entry points for pests and dampness should be sealed off properly. Silos with humidity and temperature sensors should be monitored frequently, so any grain spoilage can be detected early.
An indoor grain silo serves various industry scenarios, primarily storing grains and other bulk materials. Here are some common industry scenarios in which indoor grain silos are used:
The following tips can help farmers and business grain buyers to choose the proper indoor grain storage silos for their needs.
Determine the grain storage capacity needed
Indoor grain silos have different storage capacities. Buyers should evaluate their current and future grain storage needs. They should consider factors like the volume of grains, the height of available storage space, and the frequency of grain intake and withdrawal. Buyers can calculate the total bushels or tons of grain they store annually and project any future increases in storage needs. This will help them determine the ideal silo size for their situation.
Choose a material with appropriate durability and maintenance requirements
The most common indoor grain silo materials are steel, fiberglass, or concrete. Buyers should consider the durability, maintenance needs, and resistance to pests of each material. For example, galvanized steel has a long lifespan, but it needs regular maintenance to prevent corrosion. Also, consider how well the silo material protects grains from external elements.
Look for advanced features to improve efficiency and reduce operating costs
Many indoor grain silos now come with technological options to enhance storage management. These features include automatic grain handling systems, integrated inventory tracking, cloud-based monitoring, and remote access capabilities. While Silos with these options may have a higher upfront cost, they can significantly improve a business's storage efficiency. They can also reduce the time and labor expenditure that grain management requires. Buyers should consider investing in silos with such advanced functionalities depending on their budget and storage demands.
Assess the costs and ROI of different silo designs and providers
Several options exist for indoor grain silo design. They range from small bin systems to large silo structures. Their costs also differ depending on the design and the manufacturer. Buyers should evaluate the cost of each silo design and compare it to the benefits they will offer in terms of grain preservation, management efficiency, and durability. Buyers should also consider the reputation, service network, and support of the silo provider. They should go for providers that have a proven track record and offer excellent customer service.
