Silo Insulation
In cooling storage system, the grain cooler is not enough to keep the low temperature condition inside the silo, the cool energy could be lost within a few days, we must insulate the silo and that's why Alminco has developed insulation system. After time to time, Alminco keeps improved the insulation and obtain the patent. However, Alminco has given-up the patent and allow everyone using it on their silos, we feel proud of the way we are doing it because we believe this technology should bring benefits to all the users. The silo insulation has an bonus, the user can use the same color like the factory or put the logos and names on the insulation sidewall, it has excellent effect to use as an commercial advertisement. There are 3 parts of silo that should be taking care of, the roof, the sidewall, and the bottom. For the round silo, Alminco use PU spraying under the roof sheets for insulation (left photo). For the rectangular bins, because it has the insulation sheets on the top of bins (right photo), so there is no need to use PU anymore. The sidewall should be covered by insulation sheets, for the round silo, it needs to add extra frames so the insulation sheets can be screwed on the frames, the it helps the structure of sidewall to be more stronger. The sidewall of rectangular bins has frames already, so the insulation sheets can be screwed on directly. Only the hopper bins need to do the insulation. Alminco use special PU to spray on the hopper, and it would be better if the ducting can be covered by PU also.
Cooling Storage
Before the time of cooling storage, there are many problems in storage, so the storing period can not be long. Therefore, Alminco has cooperated with Taiwanese Government and agricultural experts to develop cooling storage system, which helps to improve the grain quality and store longer period. The advantage of cooling storage:1)Keep grains in good quality and fresh. In practical use, the paddy can be safely stored more than 3 years.2)Reduce the heat from grain itself, and prevent deterioration.3)Restrain propagation of insects and bacteria, from pratical experiences, there is no aflatoxin in the corn for 3 month in cooling storage.4)Eliminate thermal energy and maintain the quality of grain.5)Avoid condensation water inside the silo.6)Get rid of musty smell.7)Restrain paddy lipase. 8) Store in the condition that you desire, the humidity and temperature can be adjusted for different kind of grain for different purposes. The heart of cooling storage system is the grain cooler (chiller), the left photo is the water cooling type, it needs a water tower to cool down the machine, the advantage is low noise. The right photo is the air cooling type, the machine has exhaust fans to cool down the machine, the advantage is that air cooling type can be moved to use as long as there is power. Specification of Grain Cooler: (The chillers are tested in Taiwan, the performance could be changed due to different conditions at site; Alminco also reserves the rights to change specification without further notice.)

Besides, it can control the constant temperature and moisture to ensure the air condition is under control. The panel has some push button and indicator lights, the main control is done on the touch screen. It's easy to operate and it has emergency stop if the operator makes mistakes on controlling. The ducting plays an important character although it looks simple in the system. The most of the cooling energy would be wasted more than 15% if the ducting is not doing properly; therefore, it's better to insulate the ducts with PU or some insulating materials. For the ducting control, Alminco supply the close type valve with wheel handle. It's easy to open and close, there is indicator marks to show how much you can open. No matter it's hopper bottom or flat bottom, the aeration system must meet the needs of air volume to give best performance. The roof vents are also part of aeration system. Alminco supply different kinds of roof vents. When the cooling air is coming from the bottom aeration, the roof vents allow the hot air exhausting to outside, to prevent the hot air stay under the roof and become condensation. Alminco has more than 15 years experience in cooling technology, and we have reliable quality of cooling machines. Except for the local support, We also export the coolers to overseas.

Rectangular Bin Flat Bottom
The rectangular flat bottom bins are likely the rectangular hopper bins, it's more suitable to store variety kind of grains with small capacity. Each bin can be done with capacity from 50 tons to 200 tons. The rectangular bins are connected to each other to build more strength, each bin has vertical stiffeners and bracings to give maximum supports. Because there is no legs and hopper, so the total height can be shorter, which helps the structure to meet the earthquake requirement, the maximum strength can reach 7.0 on the Richter Scale. Alminco's rectangular flat bottom bin has unique design, which allows the grain discharge by natural gravity. There is another unique design that cleans up the remaining grain 100%, the user does not have to go inside and clean up anymore. Alminco retangular flat bottom bins can stand against wind load 120MPH. The bins are covered by insulation sheets, which can prevent sunlight heat, also prevent raining and water leaking. IMPORTANT FEATURE: The photo is in black & white to show the feature. There is support structure under roof sheets to support the weight of catwalk, chain conveyor, and other accessories. On the bins, there is enough room for conveyor and human service, which is save to walk. The bin has vertical stiffeners and several bracings to give maximum strength. It helps to reduce deforming after loading the grains, and also to stand against the earthquake. All the parts are connected by 8-degree galvanized bolts and nuts, to avoid rust by welding. The material of bin is made of high tension steel with painting, Alminco also supply the choice of using galvanized steel or stainless steel. The flat bottom design helps to stand against earthquake. The unique discharging design can clean out the grain, no more labor cleaning inside the bin. The flat bottom bin has full floor aeration system, which gives best performance.
