Long period storage of materials:
Caused for silo is made of steel, and for its thin wall is less than thermal capacity , the thermal conduction
and storage are affected by environment.Generally say the storage period of materials are not more than
2 months, this also limits the long period of steel silo to store material In view of these above problems,
adopt insulation combined with refrigeration way which is use of the thermal conductivity of materials
(rock wool) covered on outer-ring of steel silo and using refrigeration equipment to inlet cold air blast
to silo. This method generates results basically comparable with the concrete silo , but the cost is
effective than traditional one with long storage time.Thermal storage project is mainly used in grain
depot, farm, seed processing plants, food processing enterprises, the clients ,who use this thermal
insulation technology are effectively to control the effect caused by the changes for the external
temperature both in silo and gain temperature, delay the storehouse of grain quality, thermal
insulation effect is remarkable, in favor of steel silos and storage grain safety, greatly
promoted the development of low temperature grain storage.
Soybean storage:
Soybean is a byproduct of soybean in the extraction of soybean oil,Because of its irregular
fragmental, and its moisture content is usually slightly higher than other materials, so it is
poor in fluidity and easy to arch (part easy to become to gelosis and obstruct flow? So
we generally uses the storehouse of soybean meal, but the clearance work is intensity,
and don’t conform to the scientific development of the productive forces.
Soybean meal in the steel silo of arch and blockage problem has been plagued
by domestic and foreign designers and users, although has taken many measures,
but the effect is not ideal.
Conventional storage of rice:
Principle of keeping rice is "dry, low temperature, closed". Inatani Hide generally
widely used conventional storage method, also can use "double low" storage or
"three low" storage method. We need to use ventilation storage or low temperature
storage method before don't fully dry , in which rice conventional storage includes
the following six major measures.
1.To control the moisture of grain
Strictly control the storage of paddy moisture, make it accord with safe water
standards, safety standards of rice grain moisture changes with species,
seasonal and climatic conditions. And in order to maintain germination rate
for the seeds, the moisture which during the summer should also be lower
than the safety standard one percent.
2.Clear impurities of rice
The former requires wind , sieving or mechanical impurity, to reduced the
impurity content to improve the storage stability of rice. Usually the impurity
content of rice decreased to below 0.5%, it can improve the storage stability
of rice
3.Rice grading storage
Storage of rice need hierarchical storage, namely according to the varieties,
good times, new Chen, wet and dry, no insect insect stacked separately,
classified storage.
4.Rice ventilation cooling
Rice after storage, especially the early, mid-season , it is easy to cause feve
casued by high grain temperature, vigorous physical activity, and difficult to
distribute inner heat to leading to heap table surface condensation, mildew,
bud, and casue the lossing. Therefore, the rice storage time after cooling
and ventilation, to prevent condensation. In SEP - Oct, Nov-Dec and
Jan- Feb take advantage of the night cold air and mechanical ventilation,
will make the grain temperature from 33 to 35 degrees Celsius, at last
below to 10 degrees celsius.
5.Prevention and control of rice insect pests
After storage, especially the early, mid-season ,It is easy to infect
grain pests. Therefore, It need to take effective measures of
comprehensive control of pests after the store. Usually using
protective agent or fumigants to control.
6.Closed grain
We need to adopt effective measures to cove the surface of the
grain and keep the storage airtight while the lowest temperature
in late winter and early spring before the rising in temperature ,
inorder to keep the grain heap at low temperature (15 degrees
Celsius) or quasi low temperature (20 degrees Celsius)e.
Methods: a full closed bulk grain storehouse, plastic film cover closed.
After at last 10 years engineering practice from yongli's steel silos ,
which according to the needs ofmaterials storage cycle , had
developed a series of rice materials such as storage, actived
in exploration and research in the material circulation and
storage fieldsf , who can provide a comprehensive project
for various of materials , planning of the construction and
management of training, we are willing to work with all
customers to share experience and promote the development
of the industry inorder to enjoy a great future.
