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:Little beggar-girls with a depraved look, artful little hussies, pursued us coaxingly: "Give something, sahib, to pretty Cingalee girl, who wants to go over sea to where the gentlemens live."

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:Presently all the company is assembled, robed in long white tunics. The bridegroom, likewise dressed in white, has a chain of flowers round his neck; orchids, lilies, and jasmine, falling to his waist. In one hand he holds a bouquet of white flowers, in the other a coco-nut. A shawl, neatly folded, hangs over one arm.
  • 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:A road between ancient trees and green fields which are perpetually irrigated leads to Sicandra-Bagh. Here, at the end of a wretched village of huts and hovels, is the magnificence of a stately portal of red stone broadly decorated with white; and then, through a garden where trees and shrubs make one huge bouquet, behold the imposing mass of the tomb of Akbar the Great. The mausoleum is on the scale of a cathedral. There are two stories of galleries in pink sandstone crowned by a marble pavilion with lace-like walls; and there, high up, is the sarcophagus of white stone, covered with inscriptions setting forth the nineteen names of Allah.Huge vultures were prowling about the place.[Pg 222] At our approach they flapped a little away, and then perching on a heap of stones preened their feathers with clumsy, ungraceful movements.

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:On our way back through the temple-quarter a sudden wild excitement possessed the worshippers and priests; out of a side street rushed a large troop of monkeys, grey, with black faces. They galloped past in a close pack and fled to the trees, shrieking shrilly. One, however, lagged behind, bent on stealing some rice that had been brought as an offering to a plaster image of Vishnu. A Brahmin stood watching the monkey, and tried to scare it away with a display of threatening arms, but he dared not hit the beast sacred to Hanuman, the god of the green face. The creature, never stirring from the spot, yelled aloud, bringing the rest of the pack back on to the roof of the neighbouring pagodas. Then the ringleader, with a subdued, sleepy, innocent gait, stole gently up to the tray of offerings. He was on the point of reaching it when the priest raised his arm. This was a signal for the whole tribe to scream and dance with terror, but without retreating. The performance seemed likely to last; the bazaar and the temples were in a hubbub of excitement; the doors of the shops and the sanctuaries were hastily shut, till, at the mere sight of a man who came out[Pg 299] with a long bamboo in his hand, the whole pack made off and appeared no more, and Hardwar relapsed into its somnolent sanctity.In this Peshawur the houses are crowded along narrow, crooked alleys, and there is but one rather wider street of shops, which here already have a quite[Pg 242] Persian character, having for sale only the products of Cabul or Bokhara. The balconies, the shutters, the verandahs and galleries are of wood inlaid in patterns like spider-net. The timbers are so slight that they would seem quite useless and too fragile to last; and yet they are amazingly strong, and alone remain in place, amid heaps of stones, in houses that have fallen into ruin. In the streets, the contrast is strange, of tiny houses with the Afghans, all over six feet high, superb men wearing heavy dhotis of light colours faded to white, still showing in the shadow of the folds a greenish-blue tinge of dead turquoise. Solemn and slow, or motionless in statuesque attitudes while they converse in few words, and never gesticulate, they are very fine, with a fierce beauty; their large, open eyes are too black, and their smile quite distressingly white in faces where the muscles look stiff-set. Even the children, in pale-hued silk shirts, are melancholy, languid, spiritless, but very droll, too, in their little pointed caps covered with gold braid, and the finery of endless metal necklaces, and bangles on their ankles and arms.
  • 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.
