1, grain storage safety problems

Early application of people believe that steel CangCang wall is too thin, temperature difference is big, easy condensation, doubts about the safety of grain storage. Through practice, prove by managing the wouldn't affect the quality of the food. The moisture of grain into the storehouse is a very important problem, we will strictly control warehousing grain moisture, generally no more than 13%, such as more than 13.5% will be after the transport by mechanical ventilation cooling and precipitation. After grain into the storehouse, although because of the warehouse wall thin, incoming outside temperature easily, but the food is very good insulation, only from the wall temperature changes within 300 mm of bread. At the same time it heat fast, heat faster. When in sunny day every day at 3 PM is the highest temperature commonly period, but basically the same until 7 PM. Granary internal temperature measuring device, can therefore very convenient testing in the control room. Once the food have change, can make appropriate processing. Steel CangCang top is influenced by the outside world, temperature difference is very big, easy to dewing, therefore in the warehouse on setting the exhaust pipe and installation of axial flow fan exhaust is necessary. Set up mechanical ventilation in the bottom of a warehouse, laying pipelines, ventilation using portable fan drum wind is an effective measure to secure food supplies. Has now developed a portable cooling blast device (artificial refrigeration method), is under low temperature for 5 ~ 15 ℃ storage of grain, its effect is also very good. Storage temperature according to the actual need to maintain between 5 ~ 15 ℃, the cooling power consumption for 4 ~ 6 ℃ / t grain. Grasp the food after the ventilation technology, combined with originally from some of the food processing technology such as cleaning, screening, grading, suction dust removal, as well as management on a set of mature and complete, as applicable, turn over the two system automatically within a warehouse, etc., can make the steel silo can safe grain storage.

2, use fixed number of year

In the past, people life of granary is generally only consider the physical life, without regard to technical life. In turn in the thinking of people today, in a shortened product update cycle. Warehouse according to the purpose, the life of a place and need different, generally considered 20 to 50 years. Therefore, the steel silo can meet the needs of the technology of life. In big cities also have occurred because of the change of planning, urban commodity granary need demolition, some of the reinforced concrete silo was bombed scrap, if use prefabricated steel silo, don't blow up can be easily torn down.
In order to prolong the service life of steel silo, make the life of more than 20 years, through long-term practice proof, using standard materials and to two-sided galvanized sheet surface heat treatment or other coating processing, will be able to meet the requirements of use fixed number of year. The galvanized plate pressure into corrugated shape, can greatly enhance the strength, strong and durable.

3, the problem of material

With the rapid development of iron and steel industry, steel production, quality and variety, etc all can meet the requirements of the position. The current steel silo is made of raw material has black steel plate, galvanized steel, lead plate, aluminum, chrome plate, composite steel plate, plastic coated steel plate, steel plate, glass coating enamel steel plate, stainless steel plate, etc., can adapt to different storage materials and the storage time and the requirement of use fixed number of year.

4, perfect supporting technology

In addition to silo, steel silo must have the corresponding perfect supporting technology. Such as mechanical equipment, electrical equipment, the attitude control system, detecting device, monitoring device, technical service and so on. Mechanical equipment include: food machinery, food machinery, weighing machine, cleaning machine, fan machinery, warehousing equipment. With these mechanical equipment, to complete granary technology required in loading and unloading, transportation, cleaning, weighing, etc.
Because steel silo is high, many warehouse top and the top of the tower building is open, some top mechanical equipment is placed in the open air, therefore, operating machinery and equipment of the high Gate valve Gate had better use the way of remote control. Detection device must be configured to be complete, also including raw grain quality detection device and quick test device, temperature measuring device, the material level, full measurement devices, etc.
With these form a complete set of technical equipment, must also be on the management to do a good job of technical services, spare parts supply and maintenance services.

Due to solve the problem of the above four, steel silo get rapid development. Germans, pudong in 1968 built spiral double edge type SM is special equipment for steel silo (hereinafter referred to as the PuCang). In Germany in 1969 built the first cmpetive board positions. Pujiang the p.a. 1972 hidden in the building permission to sell all over the world to 60 countries silo engineering company. In our country in 1984 bought PuCang building permission.
PuCang it has good sealing, the quality is very good, use fixed number of year is longer, less maintenance workload, but as a result of steel consumption, low production, management fees higher factor, so the total cost is a bit high. And the Assembly warehouse due to the industrialized production, so high production capacity, lower cost, the Assembly quality can satisfy completely the requirements of grain storage warehouse, gradually accepted and approved by the enterprise.
When steel silo as flour processing plant raw material storage, select 6 ~ 10 m in diameter, and should not be too big, because the need when wheat processing with wheat, and every number of wheat varieties to appropriate, so a single warehouse capacity shoulds not be too large, otherwise it will reduce the single warehouse utilization; And as the number of grain, short storage period of steel silo, due to the varieties of a single, quantity is big, so can choose single warehouse capacity big, such as low cost, diameter of 10 m and 30 m (height) at the same time the cost will vary a lot, grain companies use steel silo bottom best with cone form, do not use flat, because the factory out food every day, cone bucket with high efficiency.
