Fluidization Characteristics of Moist Food Particles
Changes in fluidization behaviour of green peas particulates with change in moisture content during drying were investigated using a fluidized bed dryer. All drying experiments were conducted at 50 + 2 0C and 13 + 2 % RH using a heat pump dehumidifier system. Fluidization experiments were undertaken for the bedheights of 100, 80, 60 and 40 mm and at 10 moisture content levels. Fluidization beha...
متن کاملMinimum Fluidization Velocities of Binary-Solid Mixtures: Model Comparison
An accurate prediction of the minimum fluidization velocity is a crucial hydrodynamic aspect of the design of fluidized bed reactors. Common approaches for the prediction of the minimum fluidization velocities of binary-solid fluidized beds are first discussed here. The data of our own careful experimental investigation involving a binary-solid pair fluidized with water is presented. The effect...
متن کاملThe Phagocytosis of Solid Particles
1. The rates of ingestion of quartz and carbon particles by leucocytes, when both are in suspension in serum, was compared with the availability of the two particles as predicted from the calculated chances of collision with the leucocytes, and it was shown that carbon is ingested about 4 times as readily as quartz. 2. The greater ease of ingestion of carbon was verified by a new method of meas...
متن کاملThe Phagocytosis of Solid Particles
The method of preparing the carbon suspensions was essentially the same as that already described for quartz. The carbon used was one of the charcoals prepared from coal during the war by the Chemical Warfare Service and activated by treatment with superheated steam. I t was washed repeatedly in distilled water during the process of removing, by means of the centrifuge, the particles too small ...
متن کاملExperimental investigation of minimum fluidization velocity of micron size particles in presence of an acoustic field
The fluidization behavior of silica gel was tested in a fluidized bed under different sound pressure levels and sound frequencies. It has been found that the particle mixtures can be fluidized smoothly with sound assistance at low sound frequency owing to the sound energy disrupting large size of agglomerates. The minimum fluidization velocity was found to decrease with increasing sound frequen...
