This research is to design and implement a new kind of agitators called differential agitator. The Differential Agitator is an electromechanic set consists of two shafts. The first shaft is the bearing axis while the second shaft is the axis of the quartet upper bearing impellers group and the triple lower group which are called as agitating group. The agitating group is located inside a cylind...

import of 2000 tons of butter that meets parts of domestic need equals over100 million dollar per year. also we can produce butter flavouring in the product using encubation of di-acetyl mesophillic starter and yoghurt thermophillic starter  in skim milk (water phase). the sample that is produced with mesophillic starter had a better aroma in %5 level than imported lactic butter and has little ...

The effect of agitation on tho rate of acid formation by the microaerophilic organism Lactobacillus delbrueckii was studied. Fermentations xwre conducted at constant temperaturo and pW, and with the continuous addition of a nutrilite source. The range of agitator speeds was from 85 t o 720 rev/min. The acid formation rate was found t o increase with increasing agitator speetIB and dcrrease with...

Further agglomeration tests were conducted in a series of tests designed todetermine the effects of various parameters on the size and structure of the agglomeratesformed, the rate of agglomeration, coal recovery, and ash rejection. For this series oftests, finely ground Pittsburgh No. 8 coal has been agglomerated with i-octane in a closedmixing system with a controlled amou...

Blast furnace ironmaking is one of the most serious carbon dioxide emission processes. To reduce energy consumption and CO2 emissions, fluidized bed technology with hydrogen as a reducing agent has attracted more attention. An inclined agitator was added to reactor address sticking issue in conventional process. In this research, numerical simulation used examine impacts gas composition agitati...

Highly rapid and selective vortex-assisted liquid-liquid microextraction based on solidification of organic drop has been used for determination of cobalt ion. 2-Nitroso-1-naphthol (2N1N) was used as a selective complexing agent to form stable cobalt-2N1N complex which can be extracted with 1-undecanol at a short time by the assistance of vortex agitator system followed by its determination usi...

Biodiesel as an alternative and renewable fuel could be applied in diesel engines in order to reduce air contamination and dependence to fossil fuels. So far, various processes were prepared for biodiesel production, but using transesterification method via base catalyst in batch reactors could result in a reasonable yield of biodiesel. At the present study, a batch tank reactor equipped to a h...
