提高烘干機(jī)產(chǎn)量的方法有：
1.物料在烘干機(jī)滾筒內(nèi)不會作“往復(fù)運(yùn)動”。所以滾筒內(nèi)的物料很快就會被風(fēng)抽走，結(jié)果滾筒內(nèi)物料的儲存量過低，造成物料與熱風(fēng)的動態(tài)和靜態(tài)接觸面積降低。
2.為了限制物料向烘干機(jī)出口方向的流動速度，所以只有將滾筒的轉(zhuǎn)速限制的很低，這樣滾筒內(nèi)物料被揚(yáng)起的次數(shù)也大大降低。因此造成了物料與熱風(fēng)的動態(tài)接觸次數(shù)大大減少。
3.為了提高產(chǎn)量烘干機(jī)滾筒做的過長；直徑做的過大；不能充分利用；造成熱能流失；設(shè)備占地面積大。
4.為了提高產(chǎn)量進(jìn)口溫度過高；出口溫度過高；造成能源浪費(fèi)。同時(shí)也造成了被烘干物料品質(zhì)下降；物料色澤嚴(yán)重變黑；甚至糊料很多。
5.滾筒內(nèi)風(fēng)速過低，造成物料與熱風(fēng)的動態(tài)和靜態(tài)接觸力度松弛，從而造成烘干設(shè)備效率低下。
6.烘干機(jī)只有順流烘干，且干燥過程中飽和的水蒸氣又不能及時(shí)排出，這樣水蒸氣在滾筒內(nèi)運(yùn)行距離過長，造成水分被干物料重新吸收。
按以上的方法操作，烘干機(jī)的產(chǎn)量必能提高。

Improve drying machine output method:
1 The material in the dryer drum does not make" reciprocating motion". So the material will soon be the wind away, the roller material storage quantity is too low, causing the material and hot air dynamic and static contact area decreased.
2 In order to limit the material to the dryer outlet direction of the flow velocity, so only the roller speed limit is very low, so the roller material is raised greatly reduces the number of. Thus causing the material and hot air dynamic contact time is greatly reduced.
3 In order to improve the yield of dryer cylinder do long diameter; excessive; unable to make full use of; causing heat loss; equipment occupies large area.
4 In order to improve the yield of high temperature high temperature of import; export; causing energy waste. At the same time also caused a decline in the quality of the materials to be dried; serious material color black; many even paste.
5 The wind speed is too low, resulting in material and hot air and the static and dynamic contact force relaxation, resulting in low efficiency of drying equipment.
6 Only the downstream dryer drying, and the drying process of saturated water vapor and water vapor can be discharged in time, so in the long distance running, causing the material to be dried to absorb moisture.
According to the above method operation, the output will increase the drying machine.
