Description
Technical field
The utility model relates to a kind of drying system, particularly relates to a kind of multifunctional far infrared drying system.
Background technology
Infrared Radiation Technology is the branch of Modern Optics Technology, and utilize infrared radiation drying crops to be nearly new technologies just grown up for 20 years, its cardinal principle carries out drying in the mode of infrared radiation heat transfer to thing to be dried.
Infrared radiation drying crops have following characteristics: 1) uniformity; Heat transmission is directly carried out in the mode of infra-red radiation, and do not need through any medium, thing to be dried is heated evenly; 2) absorbability is good; The eigentone of different material is different, therefore also different to ultrared absorbability.All moisture content is higher for crops general, the general 5-15um of the wavelength that water easily absorbs, and the wavelength of infrared radiation heat transfer is just in this scope, and the heat of radiation can be absorbed greatly; 3) firing rate is fast, proves through experiment, and the temperature forced convertion heating reached through the infrared radiation material of 60S generally wants 10-20min; 4) avoid the loss causing thing nutritional labeling to be dried because of non-uniform temperature, and high-temperature heating is uneven and cause the rotten of thing to be dried; 5) in the process of drying, the effective killing pathogenic bacteria of energy, through the crops of infra-red drying, in the process stored, seldom can go mouldy; 6) through the crops of infra-red drying, various nutritional cost is effectively retained.
China is traditional large agricultural country, and crop products market scale reaches trillion, but China is in stable state of development to the dry technology of crops always, and at present, the dry technology of crops mainly exists following problem:
1, in the rural area that China is vast, mainly sunlight is relied on to the drying of crops, in the harvest season of crops, once it is overcast and rainy to run into continuous print, crops cannot obtain drying, the method sun to be had piled up can only be taked to be carrying out drying, often in this process, crops are gone mouldy, even goes bad and scrap;
2, conventional so far drying equipment, as pneumatic conveying drying, spraying dry, fluidized bed drying, rotary flashing drying etc. dry drying equipment, the form of heat is given in main operational principle many employings forced convertion, these drying equipments are adopted to carry out drying, mainly there is following problem: 1) longevity of service, energy consumption cost is high; 2) owing to adopting the form of forced convertion to carry out heat trnasfer, thing to be dried is heated uneven, often occur that the local aridity that heat is many is better, the place that temperature is low does not complete drying; 3) time due to drying is longer, is heated uneven, very easily causes the loss of the important nutrition of dry thing or rotten.
3, China Patent Publication No. 201310296135.2 discloses a kind of infrared drier, it adopts infrared lamp as infrared emitter to carry out drying, but according to correlation theories such as Planck law and minute surface emissivity, radiant heat transfer is subject to the impact of specular reflectivity, specular reflectivity is larger, the temperature accepting radiation by focus is also larger, and vice versa.So, although it be main forced convertion is auxiliary mode of heating that the program have employed infrared radiation heat transfer, there will be thing to be dried and to be heated unequal situation, often occur from the thing temperature to be dried close to heat-generating pipe too high and cause its nutrient loss or rotten.
4, current, the temperature in all oven dry checkout equipments mainly still relies on the mode of temperature probe to carry out, and the temperature that temperature probe records is the temperature of forced convection heat transfer in equipment.And in infrared radiation heat transfer to be main forced convertion be auxiliary heat drying mode; the heat that the heat major part that thing to be dried absorbs passes over for infra-red radiation; so often there will be thing temperature to be dried also do not reach this temperature considerably beyond the air themperature in drying equipment during setting value; there is this situation; the light then nutrient loss of thing to be dried can be made; heavy then burned scrapping occurs, great loss can be caused.
