1. Different types of grains and rice should be dried in different ways. When the rice is overdue and has not been harvested, there have been popping or explosive waist varieties in the field, a large amount of cold-damaged rice, broken rice, and unrefined rice are mixed in the rice, and the drying speed should be set to "slower". "Slow" or low temperature range, 3-4 degree lower than the control temperature. For immature rice with a lot of green grains, use a grain dryer to increase the stop moisture setting value by 5-6 percent .
2. Nquag siv ziab kom qhuav thiab tu thaum tsis ua haujlwm. Ntxuav hauv lub sijhawm, ntxuav cov nplej seem, kaw qhov nkag thiab qhov hluav taws xob, thiab lwm yam, uas muaj txiaj ntsig zoo rau lub neej ntawm lub tshuab thiab txhim kho kev ua haujlwm kom qhuav.
3. Tus nqi ntawm cov nplej thauj khoom yuav tsum tau raws li qhov yuav tsum tau ua, tsis txhob ntau dhau lossis tsawg dhau. Kev thauj khoom ntau dhau yuav yooj yim ua rau txhaws; me me loading yuav tsis tsuas yog txo cov kev khiav hauj lwm efficiency, tab sis kuj cuam tshuam rau lub ziab kom zoo. Thaum tag nrho cov nyiaj mus txog, tseem muaj ib qho me me ntawm cov nplej uas tsis tuaj yeem ntxiv, nws tuaj yeem pub tsis pub dhau 1 teev tom qab pib ziab, thiab kev pub mis tsis pub dhau 1 teev yuav tsis ua kom tsis sib xws ntawm lub tshuab ziab khaub ncaws.
4. Thaum ziab nplej thiab cov nplej uas muaj cov dej noo tsis tshua muaj siab, txhawm rau tiv thaiv kev sib tsoo, tom qab cov khoom tau pub rau thawj lub qhov rais, nws yuav tsum tau voj voog - qhuav tam sim ntawd, uas yog, qhuav thaum pub mis. Tsis tas li ntawd, yuav muaj ntau yam mob hnyav uas cuam tshuam rau cov kab mob germination, yooj yim tev, lub sij hawm qhuav qhuav, roj noj, thiab xim tsis zoo tom qab ziab.
5. The impurity content of grains should not be too high. For example, wet grains and wheat mixed with a large amount of rice straw, wheat straw and other sundries will affect the flow of grains, make some grains unable to get a good circulation, cause uneven drying, and even ferment; at the same time, it will increase power consumption, oil consumption, and reduce efficiency. Therefore, it is necessary to roughly select the grain dryer before drying.
