Description
Technical field
The invention belongs to farm equipment field, particularly relate to a kind of grain-drying storage system equipment.
Background technology
In recent years, country attaches great importance to agriculture project, and grain dry is always the major issue in agricultural production, but is a weak link in cereal postharvest treatment process at rural area grain dry.The way of airing that what traditional grain dry adopted is all; not only need large quantities of airing places, and ageing due to grain dry, need very large manpower and materials; take time and effort, have a strong impact on the scale process of agricultural production and the adjustment of the structure of rural undertaking.
Grain dry is the key in process of grain processing, has tremendous influence to grain quality.Cereal general water content when gathering in the crops is all higher, if can not dry in time, heating can go bad very soon, cause heavy losses, at memory period, cereal moisture percentage height determines the respiratory intensity of cereal, especially adopts seal-packed cereal, once moisture content is higher, respiratory intensity obviously strengthens, accelerate the nutrient consumption of cereal self on the one hand, under air-proof condition, anaerobic respiration occurs on the other hand, within very short time, the vitality of cereal will be lost.Due to the material that cereal is a kind of thermal sensitivity, the too fast or quick-fried waist of the improper easy generation of Selecting parameter of rate of drying, causes particle surface to produce microfissure, and this, by broken rice rate when directly improving cereal husk rice, affects its output and economic worth.Sum up, arrange the successful experience of domestic and international grain dry technology, for instructing grain dry operation, research and development New drying equipment tool is of great significance.
Under crop dryer is mainly used in two kinds of situations: the first situation: during grain harvest, because weather reason cannot be shone by natural track, the germination of cereal can be caused to go bad as carried out drying not in time, now apply crop dryer and drying is carried out to cereal, make the water content of cereal reach short time safety storing requirement, until natural drying bar is assorted possess after carry out natural drying again.The second situation: before cereal packaging, the moisture in cereal is reached can be preserved safely for a long time, and ensure that cereal keeps the condition of the good vitality in gallery.At this moment, natural seasoning cannot make the moisture in cereal be reduced to such degree.Drying need be carried out with crop dryer.
Facts have proved, its metabolism can be made to carry out slowly through fully dry cereal, thus extend the cereal life-span, keep higher germination percentage, there is desinsection simultaneously, suppress the effect of microorganism, make cereal more stable at duration of storage.
Current, be applied to developing of the large-scale drying equipment of common grain dry many, because the industrialization level of past cereal is very low, the equipment specially for grain dry development is little.Along with the raising of grain industry degree, also increasing to the demand of crop dryer.In order to meet the demand of wide farmers and small-sized corn processing, manufacturing and designing grain drying and there is very important realistic meaning.
Summary of the invention
The object of solar heat pump grain-drying storage system of the present invention is the problem taken time and effort to solve the airing of conventional grain storage, there is provided a kind of solar heat pump grain-drying storage system, the mode combined by solar facilities and air source heat pump equipment carries out extensive dry process to the cereal in grain storage tower.
To achieve these goals, the technical solution used in the present invention utilizes solar air heat collection case to dry the cereal in storage tower the mode that grain storage tower dry gas stream heats, then assist system with air source heat pump.When night or cloudy solar energy deficiency, air source heat pump can be opened.
Solar heat pump grain-drying storage system of the present invention, comprise solar air heat collection case, air source heat pump, air supply duct and grain storage tower, it is characterized in that: solar air heat collection case and air source heat pump pass through together with air supply duct integrated installation, air source heat pump is installed in parallel on air supply duct, and the heat exchanger of air source heat pump is installed in air supply duct; Solar air heat collection case gas outlet is by the blast pipe of air supply duct UNICOM grain storage tower bottom; In the blast pipe of grain storage tower, breeze fan is installed.
Described solar air heat collection case and air source heat pump are movable equipments, and air supply duct connects detachably with the blast pipe of grain storage tower, and one group of drying plant is equipped with the grain storage tower of more than.
Described grain storage tower is the foodstuff preservation equipment possessing air ventilation function.
The integral movable type equipment that described solar air heat collection case is made up of one group of solar energy air heat collector, solar energy air heat collector quantity increases by exporting demand adjustment.
The invention has the advantages that and use solar energy heat collection box and air source heat pump as heater means, structure is simple, energy-conserving and environment-protective, production cost be low.And temperature and humidity is all the data that can measure in the grain-drying storage intake air temperature of tower and tower, drying plant can carry out according to the ecosystem characterization of cereal and drying curve the temperature that intelligentized control method dries air-supply, 24 hours steady temperatures, elevator cycle operation can be utilized, cereal thermally equivalent can be made, realize full intelligentized control method completely.And in process of production, solar air source Drying unit is packaged type, is connected one by one with grain storage tower, carries out grain-drying drying.
Beneficial effect of the present invention is: energy-conserving and environment-protective, reduces production cost low, can dry on a large scale, accelerate industry restructuring.
