Abstract
The utility model discloses a solar energy drying device, belongs to the technical field of drying of agricultural products, and aims to overcome defects that a conventional manual drying method of agricultural products is higher in energy consumption, can produce certain pollution on the environment, is prone to produce quality failure and the like. The solar energy drying device comprises a fan, a static pressure box, a ventilation plate and a drying box, wherein a solar energy collector is obliquely arranged above the drying box and comprises a light transmitting plate, a hot air channel and an absorber plate; and the solar energy collector is fixed by a bracket, and one end of the hot air channel is communicated with an air inlet of the fan through an air pipe. The solar energy drying device is applicable to the area with sufficient sunlight during the harvesting period of agricultural products.
Description
Technical field
The utility model relates to a kind of Drying Technology of Agriculture Products, particularly relates to a kind of solar drying apparatus.
Background technology
The drying of agricultural product is the important steps in agricultural production, is also the important component part that realizes Agricultural Production Full Mechanization, still guarantees the key link that agricultural product quality is up to standard simultaneously.Agricultural product generally all contain a large amount of moisture when just results, can't for further processing or storages, but also very easily germinate, go rotten, cause the decline of quality and the loss on total amount.So agricultural product are once results, just should carry out in time drying and process, wherein moisture is removed. dryly can be divided into natural seasoning and the large class of artificial seasoning two by method.Adopt the natural drying method history of existing several thousand in the agricultural production of China, mainly to utilize sunshine solarization and natural wind to blow to make agricultural product reach dry purpose, need to take larger airing site area, and dry efficient is very low and will consume more labour, therefore, fewer employing now.At present, in the agricultural production of China, the drying to agricultural product is mainly to utilize the artificial seasoning of drying machinery and drying equipment.The advantages such as rate of drying is fast although artificial seasoning has, and the thermal efficiency is high, and homogeneous heating is saved the labour, and the occupied ground space is few; But, because drying machinery and drying equipment all must have heating equipment, consume more heat energy or electric energy; The most areas of China also with coal as thermal source, can be to some extent to environment; In addition, adopt the method for artificial drying, also easily because managing and operational error, cause baking temperature too high, rate of drying too fast and the quality of agricultural product is degenerated, the percentage of seedgermination reduction.
Summary of the invention
The purpose of this utility model is to provide a kind of solar drying apparatus, overcomes present drying to agricultural product and adopts the existing energy consumption of artificial seasoning higher, can cause certain pollution to environment, easily produces the deficiencies such as Quality Failure.
The utility model is achieved by following technical proposals.
The utility model comprises blower fan, plenum chamber, ventilative board and drying box, is provided with obliquely solar thermal collector above described drying box, and described solar thermal collector is comprised of light-passing board, hot-flow flue, absorber plate; Described solar thermal collector is fixed by support, and an end of described hot-flow flue is communicated with the air inlet of described blower fan by airduct.In the technical program, described solar thermal collector arranges obliquely.This is because China sentences the Northern Hemisphere, and most area is all to the north of the tropic of cancer, be subject to the area of sun direct projection seldom, and most of agricultural product all will even be gathered in the crops near the winter solstice after the summer solstice, the tilting purpose of described solar thermal collector is in order to make the angle of meeting to the one side of the sun and sunray as far as possible near 90 °, can to receive more illumination.Described light-passing board can adopt glass or transparent plastic sheet, and absorber plate adopts the not plastic plate of reflecting coating of outer coating black, and in a word, described solar thermal collector is because area is larger, so should adopt as far as possible light material.Simultaneously described support be connected the connection of solar thermal collector and want firmly, the windproof effect of keeping off the rain in addition except the heat of collecting sunshine of described solar thermal collector.
To absorb heat equably in order making through the whole described absorber plate plate face of the even cloth of the air flow energy of described hot-flow flue, between an end of described hot-flow flue and described airduct, surge tank to be housed.Adopted guide vane device of the prior art in described surge tank, made negative pressure that described airduct produces can be dispersed throughout more equably an end of described hot-flow flue.Outside at described absorber plate is provided with heat-insulation layer, can reduce the heat loss of the backward outside of described absorber plate temperature rising.
Against existing technologies, the beneficial effects of the utility model are:
Energy savings, free from environmental pollution; Low temperature drying can guarantee that the quality of agricultural product is unaffected.
Description of drawings
Fig. 1 is structural representation of the present utility model, and Fig. 2 is that the A of Fig. 1 is to view.In figure: 1, blower fan, 2 plenum chambers, 3, ventilative board, 4, drying box, 5, solar thermal collector, 6, light-passing board, 7, hot-flow flue, 8, absorber plate, 9, support, 10, airduct, 11, surge tank, 12, heat-insulation layer.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and the specific embodiment.
The utility model is one and has not only utilized the heat energy of the sun but also utilize the formed air-flow of natural air to the withering improved technique of agricultural product.In embodiment as shown in the figure: blower fan 1, plenum chamber 2, ventilative board 3 and drying box 4 are common equipment in present comparatively popular hot air type drying device; During enforcement, can auxiliary heat supplying and heat transmission equipment be set for the utility model, in order to overcast and rainy, evening or in particular cases use at other.The utility model should make every effort to allow the angle of sunray and light-passing board 6 near 90 ° for the angle of inclination of solar thermal collector 5 when mounted, can determine according to the geographical position of locality and the irradiating angle of required drying farm products sun harvest time.The utility model offers airflow kinetic energy by blower fan 1 in use.Natural air becomes thermal current after entering hot-flow flue 7 by an end of solar thermal collector 5 and absorb the heat that is distributed by the absorber plate 8 of the sun heat by light-passing board 6 in flow process, enter plenum chamber 2 by airduct 10, blower fan 1 after all being pressed by surge tank 11 again, be divided at last the tiny thermal current of one strand and enter 4 pairs of dry processing of agricultural product enforcement of hothouse through ventilative board 3.
