Description
Technical field
The invention belongs to grain store field of engineering technology, and in particular to it is a kind of prevent grain heap wall condense silo and its
Application method.
Background technique
Grain is the grand strategy goods and materials to involve the interests of the state and the people, and China develops earliest as View of Grain Storage Technoiogy in the world
One of country, with being continuously increased for grain yield, the task of foodstuff preservation is increasingly heavy.It is counted according to agricultural sector, China
Grain post-harvest loss rate is more than 8%, wherein storage link loss late is up to 5%, thus efficient View of Grain Storage Technoiogy becomes outstanding
It is important.The biological factors such as the abiotic factors such as temperature, humidity, Tiny pore and microorganism, grain storage pest are to influence grain storage life
An important factor for state system.China's annual grain postpartum finds and disposes not in time initiation because moisture condensation occurs in storage
Entomophthora harm, causes heavy losses to grain.
The warehouse structure of silo is an important factor for causing grain heap to condense, and the wall of most building and the external world all have gas
Body exchange, i.e. ambient atmos are affected to close to the grain layer of silo wall surface, and grain is the non-conductor of heat, heat transfer compared with
Slowly, larger to condense close to humidity when outer temperature is lower than grain temperature.The existing scientific grain-storing bunker equipment in China is insufficient, skill
Art is backward and energy consumption of aestivating is higher, is not able to satisfy the demand of landlord, although family's agricultural production lesser for grain storage demand, falls behind
Grain storage technology also easily causes the loss and waste of grain.Traditional kiloton stockpile grain is excessively simple and crude, and there are constructions not to advise
Deficient demonstration, Duct design be not scientific safely for model, structure, it is not in place to protect grain measure, disengaging operation is dangerous, managerial experiences are immature
Etc. risks and hidden danger.Just because of grain storage equipment simple and crude so that managed during grain storage it is even more extremely difficult, cannot have one more
Properly solve the problems, such as that grain heap condenses with more efficient management method.Large-scale grain storage equipment does not have practical for peasant household
Property, it will increase the production cost of peasant household, waste of resource.
Application No. is CN 2017111428577, the patent of invention Shen of a kind of entitled grain storage freezer and storing grain method
A kind of grain storage freezer and storing grain method please be disclose, outdoor cold air is stored in freezer in winter, by storage when summer
Cold air is recycled in grain storage warehouse cools down to grain storage warehouse, and the patent of invention is using winter storage cold air come to grain
Cooling down, summer comes for silo cooling, but structure is complicated, and it is grain storage freezer operation and maintenance higher cost, complicated for operation, no
It is suitble to peasant household to use.
Summary of the invention
Goal of the invention: the deficiencies in the prior art are directed to, the purpose of the present invention is to provide one kind to prevent grain heap wall
The silo of wall moisture condensation.It is a further object to provide a kind of application methods of silo for preventing grain heap wall from condensing.This
Invention is extracted with draft type to grain heap surroundings wall using the cold heart of grain heap itself winter cold-storage storage, is realized effective balanced
Grain temperature reduces grain heap wall condensation trouble, can meet smallholder's production inventory demand, guarantee that grain security aestivates and saves energy
Consumption effectively realizes grain heap itself cold energy use and storage function.
