description | Grain of high humidity, as a rule, is characterized by the excessive non-homogeneity of this indicator. (Purpose of research) Calculation and experimental verification of the handling capacity of the grain drying facility with the original unaltered humidity and the capacity of the binning bunker. In the dryer of continuous functioning uneven drying is not as large as in the dryer of periodic action, the dried grain is get mixed in the reloading and transporting devices. The degree of mixing, and hence the degree of equalization of the dried grain mass by humidity depend on the type and design of thesedevices, but the moisture content of individual grains is not equalized. (Materials and methods) It was noted that the mosteffective drying uniformity is achieved by recycling method. It is used in agriculture rarely, but circulation method is used often, especially in periodical drying. During circulating drying of grain in the over-drying bunker there is a bin, in which the moisture content of individual grains is leveled. Assuming that the moisture content is leveled by means of contact mass transfer, mathematical modeling of the grain drying process with higher initial unevenness is carried out. (Results and discussion) It was found that, when one dries grain with less homogeneous humidity, to obtain high quality grain, it isnecessary to reduce the input bandwidth of the plant or equip it with a bin with a higher grain capacity. (Conclusions) The input bandwidth capacity of the periodic plant for grain is a function of the capacity of the brew hopper, the speed of the contact mass transfer, the number of cycles and the unevenness of the initial moisture content of the grain. The capacity of the binning hopper is equal to the product of the initial irregularity of the drying, and the capacity of the drying chamber divided by the contact mass transfer. Business analysis of grain drying with unaligned initial humidity is done |
