Description
Technical field
The present invention relates to the slow dry storage system of ventilating of the full end, a kind of whole storehouse.
Background technology
Along with social progress, China tradition farming practices are just progressively to mechanization, intensive, scale transition, but store up processing mode in early stage taking airing as main grain, still restrict so far the development in an all-round way of agricultural revolution.
It is harvesting, airing, storage that the grain drying of China's agricultural is stored up management mode.If the harvest season is at a time when rainy season or successive cloudy days, the frequent Moisture high UCL of grain of purchase or too high, grain depot must pass through redrying processing, otherwise very easily goes mouldy after warehouse-in, easily causes the grain damage of whole storehouse.Airing and oven dry to this traditional method.
Airing just needs enough places and fine weather condition, utilizes solar energy that grain moisture content is converted into gaseous state.Former peasant household disperses, under the condition of small-scale production and small depot keeping, to adopt the method to have some superiority.But along with soil falls sharply, labour reduces, can be fewer and feweri for place and the labour of airing, Geng Duo peasant household directly sells the high-moisture grain of mechanical harvest, has increased the burden of storing up with processing enterprise.Therefore storing up with processing enterprise generally adopts dryer mode to reduce moisture.
Dryer processing method is one of effective method the most at present.It is to utilize special equipment that the heat of higher temperature is provided, and cement out the moisture of grain within a short period of time.
Concrete operations are that grain flows in dryer, and by concentrated thermal energy transfer, to grain, making the water transform in grain grain is that gaseous state is discharged.Its application needs certain professional knowledge: strictly control the bake out temperature of grain different humidity, several main grain kinds are had to different baking temperatures and technological requirement, must be equipped with a large amount of auxiliary equipment; Dryer can be processed high-moisture grain more in enormous quantities (several tons to tens of ton/skies), and precipitation range is larger, drops to 13% left and right from 30%; But need supporting technology personnel, special place, large-scale grain transporting equipment and conveying people, every day, dry tens of tons were to hundreds of tons, careless manipulation will dry grain overdrying, even be charred, each dry amount is few, and every day, the number of turnover and frequency were higher, had increased labour intensity and pollution intensity, because precipitation range is large, speed is fast, is difficult to ensure the quality of grain: one-level rice rate lower (only having tens percent), the grain of rice is easily broken.
Drier method is in China's initial stage extensive style batch production, processing speed is fast, quality requirements is not high, prevent that grain from damaging, in storage warehouse-in, really play a significantly greater role fast, but long-term storage also exposes a lot of deficiencies, each dry degree difference, after warehouse entry, add that force ventilation has dead angle, the large and moisture of the temperature difference is poor easily to be caused mould to grow and goes mouldy even rottenly, is the very large hidden danger of Downstream processing enterprise safety operation existence.
Have at present a kind of grain with regard to the slow dry technology in storehouse, be at grain from producing, the mechanization of harvesting, dry, storage overall process, realize grain-production to " not the landing " of circulating.After grain purchases, first adopt large-scale dryer to be dried or flash baking reduction portion of water, then warehouse-in.Air themperature is raise 5～8 DEG C and utilizes force ventilation that moisture is slowly dropped to below safety line, and this technology is called as with regard to the slow dry technology in storehouse, and the moisture in grain is slowly cemented out, and drying effect is of little difference with airing, has kept grain quality completely.But the provision price of processing is like this high.
China is engaged in the dry research experiment of grain during procedure of storing grain more than 40 years, and obtain rich experiences, but it is more to have problems, because the main flow storehouse type of China is chamber storehouse, ventilation equipment carries out design configurations by the requirement of Grain Ventilation cooling, dead corner region is many, thus cause for many years with regard to storehouse mechanical ventilation drying technology rest on higher moisture processing stage, distance is applied still far away.
Research both domestic and external shows, in storehouse grain heap high become with regard to the bottleneck of storehouse mechanical ventilation drying, just because of this, for many years, China, East Bloc and the similar country taking chamber storehouse as main storehouse type, the mode that large high moisture grain of direct buying new results from field is put in storage, all takes careful attitude.It is crucial is exactly to lack high-moisture grain to carry out the extensive effective technology means of processing.
Along with growth in the living standard, people more and more pay close attention to the safety of grain, are returned goods because of mouldy in sitotoxismus, Grain and Cooking Oil Processing Factory, and the aflatoxin event such as exceed standard is grain drying to a great extent, hide some dangers in storage and cause.
For the present situation of drying generator, " the slow ozone sterilization drying equipment of silo low temperature " and the dry technology once developed, i.e. " dry in storage " form, evenly be distributed into grain heap by ventilation duct, utilize drier gas to pass into grain heap and displace the grain heap gas that moisture content is high, a kind of precipitation method that causes grain moisture content to decline.This method is to process under the condition of having put in storage at grain.In the higher area of humidity, adopt and add hot-air and mildewproof sterilized, ensure grain security and the quality of dry run.The method changes the pattern of storing up of China's grain, causes a kind of brand-new grain drying and grain and stores up management mode, has realized not landing from grain harvest to storage overall process.
But in actual mechanical process, because pipeline is more, if reserves are the horizontal warehouse of 6000 tons, the pipeline total amount of use reaches more than 1,400, installation period long (10 groups of complete equipments being installed, one week of need), stringing labour intensity is large.
