“She would forget our brief encounter”- Who said and about whom? What is the ‘brief encounter’ referred to here? Why did the speaker think so? Answer: In Ruskin Bond's 'The Eyes Have It', the narrator said "She would forget our brief encounter" and here 'She' is referred to the girl companion. The lively, light-hearted conversation between the narrator and the girl regarding the beauty of the hills of Mussoorie in October and about the view of landscape from the train’s window between Rohana and Saharanpur has been described as the brief encounter. When the speaker informed the girl that her station will arrive soon, she felt quite relieved. On the contrary, the speaker was ready to sit in the compartment for any length of time just to hear the girl talking. The journey that was cherished by him was of little importance to her. This differing emotion made the speaker feel that the girl would forget their brief encounter.

SPRAY DRAYER Principle: ü The feed solution consisting of dispersed core in coating solution is sprayed through an atomizer (produces fine droplets) from the top of the spray chamber. ü As the liquid feed moves downward, it interacts with circulating hot air. ü Thus solvent present in droplets gets evaporated, as a result of which dry microcapsules are formed. ü Drying is achieved in a very short time i.e., even before the droplets, reach the bottom of the drying chamber (usually 2-3 seconds). ü Spraying the droplets of sufficient smaller size and subsequent interaction with hot air is the important step in whole process. Construction: ü Spray dryer consists of a spray chamber and a separating chamber (cyclone separator). ü They are interconnected by means of a narrow pipe. ü An atomizer is fitted at the top of the spray chamber which sprays the feed as droplets. ü An inlet for hot air (or gas) is present at the top. ü The entire ...
Planetary mixture Principle It operates on the principle of shear that develops in between the stationary wall and rotating blade. The blade moves around its own axis and also around the central axis which makes it reach every part of the vessel, due to which efficient mixing is achieved. The blade also consists of plates that are slightly sloped in order to enable in the upward movement of the material, thereby inducing tumbling motion. Construction It consists of a C-shaped hard metal body provided with a flat bottom and a gear box along with motor at the top. A vessel is placed on the flat bottom, into which a blade is suspended. The blade is connected to the gear box with the help of a shaft. A support is fitted at the center of the body for holding the blade shaft. The equipment is constructed in such a manner that the vessel and the blade (along with shaft) can be easily removed by slightly raising the blade shaft. The speed of...
FBD Principle: In fluidized bed dryer, hot air (gas) is passed at high pressure through a perforated bottom of the container containing granules to be dried. The granules are lifted from the bottom and suspended in the steam of air. This condition is called fluidized state. The hot air (gas) is surrounding every granule to completely dry them. Thus material or granules are uniformly dried. Construction: Two types of bed dryer are available, vertical fluid bed dryer and horizontal fluid bed dryer. The construction of vertical fluid bed dryer is shown in the picture. · The dryer is made up of stainless steel. · A detachable bowl is placed at the bottom of the dryer, which is used for charging and discharging. · The bowl has a perforated bottom with a wire mesh support for placing material to be dried. · A fan is mounted at the uppe...
