TWO:Steaming over the transparent and intensely blue sea, we presently perceived an opaquer streak of sandy matter, getting denser, and becoming at last liquid, extremely liquid, yellow mudthe waters of the Ganges, long before land was in sight. Between the low banks, with their inconspicuous vegetation, a desolate shore, we could have fancied we were still at sea when we had already reached the mouth of the sacred stream. Some Hindoos on board drew up the water in pails to wash their hands and face, fixing their eyes in adoration on the thick sandy fluid. Enormous steamships crossed our bows, and in the distance, like a flock of Ibis, skimmed a whole flotilla of boats with broad red sails, through which the low sun was shining. The banks closed in, the landscape grew more definitetall palm trees, plots of garden ground, factory chimneys, a high tower. On the water was an inextricable confusion of canoes and row-boats flitting among the steamships and sailing barks moored all along the town that stretched away out of sight.

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:They were clad in colourless rags, matted and grizzled hair hung about their pain-stricken faces. The woman was the more delicate, her bones smaller and less knotted than those of the man, whose joints were gnarled, his scraggy knees forming thick bosses of bone above his shins. They threw themselves like hungry animals on some cooked grain which Abibulla brought out for them, and then, with scared looks all round, they went quickly away, as quickly as they could with halting, weary feet, without even saying thank-you.Another templecarved and pierced, and loaded and overloaded with ornament. In the crypt was a bas-relief representing the ceremony of marriage: the procession, the couple in front of the altar, the relations sitting round, all alike in the same crouching attitude, like toys set out by a little child. Then the model of a very famous temple elsewhere in India: columns, gateways, statues of the gods, all reproduced with microscopic exactitude down to the minutest details; and surrounding this tiny model a bas-relief of the most bewildering perspectivea plan of Satrunji with its fifty-two principal temples, its trees and sacred tanks; and as a pendant to this representation, a circular carving giving a bird's-eye view of the crowd, the same little doll-like figures[Pg 79] repeated again and again, coming to worship with arms and legs spread out, grovelling, as if they were swimming.

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:[Pg 94]
  • 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:

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: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.Deeply graven in the stone of one of the walls is the giant hand of Ali the Conqueror, the terrible, who came from the land of the Arabs, killing all on his way who refused to be converted to Islam. And he died in the desolate Khyber, where all who pass do him honour, and entreat his protection on their way.
  • 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.
