TWO:Trees shut in the flat, interminable road, and it was midnight before we reached Srinagar, where I found, as a surprise, a comfortable house-boat with inlaid panels, and a fragrant fire of mango-wood smelling of orris-root.>At the top of Malabar Hill, in a garden with freshly raked walks and clumps of flowers edged with pearl-shells, stand five limewashed towers, crowned with a living battlement of vultures: the great Dokma, the Towers of Silence, where the Parsees are laid after death, "as naked as when they came into the world and as they must return to nothingness," to feed the birds of prey, which by the end of a few hours leave nothing of the body but the bones, to bleach in the sun and be scorched[Pg 30] to dust that is soon carried down to the sea by the first rains of the monsoon.

After taking into consideration of the physical and chemical property of solutions, the desired design conditions, and available utilities, we select the most suitable type of system by utilizing our years of experience and excellent results.
In addition, we can offer designs and manufacturing services that take into careful consideration compactness, energy-efficiency, and automatization.

THREE:Inside, after going through a long array of rooms filled with sham European furniturehandsome chairs and sofas covered with plush, Brussels carpets with red and yellow flowers on a green groundwe came to the throne-room, an enormous, preposterous hall, which, with its rows of cane chairs and its machine-made Gothic woodwork, was very like the waiting-room or dining-room of an American hotel.

While standard calandria type evaporation systems are widely used as the typical concentration evaporator by the various food and chemical industries, we have delivered many of those systems as finishing concentration evaporators especially for sugar solutions and starch syrups.

THREE:After breakfast a party of jugglers appeared in front of the hotel; they performed on a little carpet spread under the shade of a banyan tree. Acrobatic tricks first, human ladders, feats of strength; then nutmegs were made to vanish and reappear; and finally they conjured away each other in turn, in little square hampers that they stabbed with knives to prove that there was nobody inside;[Pg 11] and to divert the spectators' attention at critical moments they beat a tom-tom and played a shrill sort of bagpipe.
  • Enables flexible operation with little influence from variations in load and raw solution concentrations because of an adequate amount of solution being held within the system. These systems are also suitable for batch type burning evaporators.
  • Concentrations can be controlled within product specifications by the cascade control using the concentrations of concentrated solution and the raw solution supply and also by the arithmetic control of raw solution concentrations, etc. (Result for sugar solutions: 75±0.2wt%)
  • High-viscosity solutions and solutions that may crystallize can also be utilized by installing a propeller in the evaporator as a forced circulation system.
THREE:As we stood up there the caravan for Cabul came in sight on the road below, and slowly disappeared wrapped in dust, with mechanical steadiness and[Pg 250] without a sound. After that came the other train of travellers from Peshawur, singing to the accompaniment of mule-bells, every sound swelled by the echo. Children's laughter came up to our ears, the scream of an elephant angry at being stoppedeven at a distance we could still hear them a littleand then silence fell again under the flight of the eagles soaring in circles further and further away as they followed the caravan.And again ruins. Under an archway still left standing on piers carved with lilies and foliage, lay a whole family of pariahs covered with leprosy and sores.

This is a process example of a device that continuously and simultaneously concentrates two types of waste liquid with a single high-efficiency steam compressor.

THREE:
  • By evaporating the steam using a mechanical compressor and reusing it, almost no heating steam is alomost required except the time of start-up, so large energy savings can be expected.
  • By combining with a thin film falling heat exchanger that does not raise the boiling point due to the liquid depth, it is possible to utilize the temperature difference of the compressor at the maximum.
  • Since the residence time and heating time are short and the holding amount is small, starting and stopping can be performed in a short time.
  • It will prevent scale adhesion in the can that the evaporator is divided into two parts, and that the supply of the undiluted solution is alternately switched over a fixed period of time to perform heat concentration.
