Abstract A solar drum dryer was designed and constructed for paddy drying, including a fixed outer inner perforated drum, which rotated at the desired rotational speed inside drum. The maximum capacity of 10 000 g. controlled. thermal energy required provided by absorber plate. performance examined three levels (0.21, 0.42 0.84 r.p.m.), slope (1°, 1.5° 2°) air velocity (1.7, 1.8 1.9 m.s−1). dia...

This paper proposed a new process control strategy for reducing banding artifacts in electrophotographic (EP) processes. EP banding artifact is shown to correlate to the fluctuation of the organic photoconductive (OPC) drum angular velocity. Improved regulation of the OPC drum rotational velocity under various process uncertainty and variations will significantly improve EP process stability an...

In order to solve the problems of high millet agglomerates rate, damage and undelivered net loss rate in process mechanized harvesting millet, a longitudinal axial flow-staggered flexible threshing device for was designed on basis existing device. The “staggered teeth” drum micro rotating circular tube concave screen work together realize low millet. pre experiment carried out first, factors th...

The chili pepper harvester has shown potential problems of low stem separation and a high damage rate. required additional labor, which consists separating the after harvesting. To improve sorting function harvesters, three-shaft four-shaft drum-type stem-separation devices were manufactured, performance tests conducted to assess these devices. In an attempt reduce rate, brush was used as teeth...

the objective of this study was to evaluate different pistachio hullers and determine the proper harvest time of pistachio nuts for hulling. three pistachio hulling machines (helical drum, helical- blade drum, rubber drum) at three harvest times and 15 days interval were evaluated. the hulling efficiency, percentage of damaged nuts, faulty hulled nuts and unhulled nuts were measured at each tim...
