TWO:The fog seemed to turn to solid smoke, impenetrably black, wrapping us in darkness which was suddenly rent by a red flash, blood-red, ending in a green gleam. The mist retained a tint of sulphurous copper for some time; then a second flash, and far away among the lurid clouds we had a glimpse of the Himalayas, pallid purple with green shadows against an inky sky. The[Pg 254] thunder, deadened by the masses of snow and very distant, rolled to and fro with a hollow sound, frightening the horses which struggled uphill at a frantic pace. And the dense fog closed round us once more, a dark green milkiness streaked with snow, which was falling in large flakes formed of four or five clinging together like the petals of flowers. Then it hailed, which completely maddened the horses, and then again snow, and it was literally night at ten in the morning when at last we reached this spot and the shelter of a bungalow.All round Domel there were fields of lilac lilies among the silky young grass, and the cliffs were[Pg 271] hung with a yellow eglantine exhaling a penetrating scent of almonds.

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:Then the sunset, in the furnace of heavy purple and red, reflected in the water in fiery copper-colour streaked with violet, till soon it all faded together, to gold, to lemon-colour; the mist rising from the river spread over all the country, and everything looked the same in the cloudless gloom. One quarter of the sky glowed faintly, through the haze a crimson globe rose into view, the moon appeared, and soon lighted up all the sky with a soft greenish glow, pallid but deep, lying on the tranquil Ganges in broad rippling sheets of gold and green, spangled with light where a fish leaped, or a white bird dipped its wing as it skimmed swiftly across without a sound. The gold grew cold and dead, the moon turned to steel against the intensely blue sky, to cold blue steel on the lustrous face of the waters.

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:The scenery was preposterous: red and green flowers growing on violet boughs, with forests in the background of pink and yellow trees; perspective views of streets, in which the houses were climbing over each other, and finally a purple cavern under a brilliant yellow sky.
  • 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:In every shop of the High Street jewellers are on the look-out for customers, hale them in, tease them to buy, and open for inspection little bags or cardboard boxes kept in safes, and containing the finest sapphires in the world. The day slips by in bargaining for the gems, in endless discussions and feigned departures. The indefatigable vendors return to the charge, run after the customer, wait for him at the door of a rival dealer, and drag him back again. Then there is a fresh dispute over prices, till irresistible argument at last brings down the estimates to a third or a quarter of what they were at starting.

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:In the native town the houses are lower and closer together, without gardens between. Down the narrow streets, between booths and shops, with here and there a white mosque where gay-coloured figures are worshipping, or polychrome temples where bonzes are drumming on deafening gongs, run tramways, teams of oxen, whose drivers shriek and shout, and hackney cabs, jingling and rattling. Among the vehicles there moves a compact crowd of every race and every colour: tall Afghans, in dingy white garments, leading Persian horses by the bridle for sale, and crying out the price; bustling Parsees; naked Somalis, their heads shaven and their[Pg 7] oiled black skins reeking of a sickening mixture of lotus and pepper; fakirs, with wild, unkempt hair, their faces and bodies bedaubed with saffron and the thread of the "second birth" across their bare breast; Burmese, with yellow skins and long eyes, dressed in silks of the brightest pink; Mongolians, in dark-hued satin tunics embroidered with showy colours and gold thread.There was not a sound, not a bird, excepting on the fringe of the forest. As we penetrated further there soon was no undergrowth even on the dry soil, between the ever closer array of trees; the creepers hung very low, tangled with clinging parasites; and between the stilt-like and twining roots and the drooping boughs, the path, now impracticable, suddenly ended in face of the total silence and black shade that exhaled a strong smell of pepper, while not a leaf stirred.
  • 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.
