China Rice Husk Paddy Grain Dryer

Brief Introduction of Grain Dryer
The grain dryer as vertical small grain dryer machine is mainly drying for wheat, corn, rice, beans and other rush in the harvest of food crops. Drying operation to adapt to different locations, different sizes designed specifications, multi channel wind capacity, needn't civil, meet large and small enterprises, access to millions of households. The new technology of drying cycle high moisture grain into the safe moisture one time have contributed for national food security and income increase of agricultural and rural farmers. The device is a powerful impetus to enterprise development, led the industry's technological progress similar products to drive the industry to optimize and upgrade products. Users can select different sizes of small grain dryer by the scale of agricultural production and grain drying capacity. Small grain dryer is mainly used for drying high moisture rice, wheat, corn, soybeans and other grains, suitable for farms, granaries, grain specialized households use.

Grain Dryer Features
1.Small grain dryer device is of simple structure, small in size, easy to operate without auxiliary equipment,
easy to transport and move.
2.Small grain dryer uses hot air as drying medium, adopts cyclic drying process, grain is uniform heating,
full raining, good quality after drying.
3.Small grain dryer use coal, rice husk or straw as fuel, after combustion and heat transfer the hot air into
a clean, pollution-free grain being dried.
4.The small grain dryer is low investment and working cost, can control the work process automatically, automatically shut down, simple effort to meet the needs of small and medium farms and farmers.
5.The grain dryer is equipped with automatic on-line temperature measurement, moisture measurement devices, high automatic level and good dry uniformity.
6.Cleaning is convenient,completely, not mixed seeds, particularly suitable for drying grain seeds.

Problems and Solutions

Unusual situationReasonSolutionsDry uneven
The remnant fragment dust waits for in excessively many drier parts to block does not circulate.Please try to eliminate the remnant fragment dust and so on. before the grain has not loaded the dryer, to screen first after the rougherThe rice, the wheat, the sorghum moisture is too high in the dryer the bridging. enters the valley by 1~2 window's quantity dry (on the one hand dry on the other hand to enter valley) dryBefore dry grain moisture deviation big (immature grain excessively many)If the initial period moisture has time 3~4% moisture difference, please distinguish dry, or the moisture high grain dry to when is the same with the low moisture, the only then may mixes in together dry or uses two section of dryness. when dry machine spends too longThe hot-blast temperature is somewhat lowPlease refer to the thermometer adjustmentArranges the wind moisture backflowThe exhaust duct must pull outside.Exhaust blower's air hose accumulates the dust or the orifice has the obstacle, causes the fan efficiency to be low.The elimination accumulates the dust and the obstacle.Before the dry moisture is excessively high.Please correct determination initial period moisture.The atmospheric humidity is high.When the atmospheric humidity surpasses above 90%, please raise according to the thermometer the hot-blast temperature approximately 2~3ºC.Arranges the wind eta path, the hot wind eta path cleaning mouth has not covered.Be good each cleaning opercula .Arranges the wind air hose to arrive at the strength very approximate amount of wind to be low.Please adjust the exhaust duct gusty area according to the regular application method.Torso cracks grain of and broken grain of very multi-Before dryness sheds skin, partly sheds skin many.The attention harvests when with threshing machine's rotation, the rice which partly sheds skin slowly do be please dry by the low temperature.Hot blast hyperpyrexiaPlease note the hot-blast temperature and invests valley measureAfter dry processing badCompletes after dry the grain cannot deliver the cold wind to cool immediately, and avoids contacting the moisture.Dry (has done) the water content to be lower than 12% excessivelyPlease often determine the moisture in the dryness, and pays attention to the blue rice the proportion, time cut-out's time setting do not have the errorBefore the dry, torso cracks excessively manyThe attention harvests the date, cannot harvest ripeCirculates badReversing valve blocking, please inspect the adjustment, particularly drier part.Humidity when 65%, the drying velocity is quickHumidity when 65%, the drying velocity is quick, asks to surrender low 3~4ºC hot-blast temperature dry itRemnant valley measure has not eliminatedLower part after the dry, elevator, on lower part the feeding screw, flows the valley tube base the remnant valley to clean.Elevator ladle attritionWhen ladle attrition must replace itHarvests the late rough riceAsks to surrender low 3~4ºC hot-blast temperature dry itThe few grain are dry by the long timeSurpasses are few when should avoid often circulating, please by low temperature interrupted cyclic dryingThe feeding screw rocks with the collection yard lumber contact.Pays attention to the feeding screw not to be possible with under yard lumber friction, if has the friction to try to adjustExcessively dryBefore the dry moisture difference is too bigAfter ventilating the circulation, dry the moisture difference is too again big when do not together dryBlue rice immature rice too muchAt the right moment harvests please to use two section of dry.
