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: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.Last year he and his brother had gone into the mausoleum of a Moslem saint with their shoes on; both had gone mad. The other brother died in a madhouse, where he was cared for; this one, incurable but harmless, went about the highways, followed by the dogs.

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:We could see the procession coming straight up a hollow ravine from the valley to the Dokma, a path that none but Parsees are allowed to tread;[Pg 31] eight bearers in white, the bier also covered with white, and, far behind, the relations and friends of the dead, all robed in white, two and two, each pair holding between them a square of white stuff in sign of union. They came very slowly up the steps of the steep ascent with a measured chant, in muffled tones, on long-drawn vowels. And from the surrounding trees, from far and near, with a great flutter of wings, the vultures flew to meet the corpse, darkening the sky for a moment.
  • 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:More temples, each more stupendous than the[Pg 41] last, and more halls hewn in the rifts of the hills, and over them monks' cells perched on little columns, which at such a height look no thicker than threads.At Roza, the plateau above the Hindoo sanctuaries, above a dozen of Moslem mausoleums are to be seen under the spreading banyans that shelter them beneath their shade, and sometimes hide them completely; the white objects are in a whimsical style of architecture, hewn into strange shapes, which in the doubtful starlight might be taken for ruins.

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:Down the middle of the Ganges a white bundle is being borne, and on it a crow pecking the body of a child wrapped in its winding-sheet.
  • 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.
