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:Even more than the assembly of their relatives and friends, the prisoners at the bar maintained the impassive mien of men who attach no disgrace to a sentence pronounced by a conquering race; they would take the penalty without a murmur, as one of the inevitable incidents of this life, which to them is but a stage, a passage to a higher existence.In a little alley of booths was a shop with no front show, and behind it a sort of studio full of carvers and artists working on sandal-wood boxes, ivory fans as fine as gauze, and wooden lattices with elaborate flower patterns, used to screen the zenana windows. And in little recesses workmen dressed in white, with small copper pots about them in which they had brought rice for their meals, were chasing and embossing metal with little taps of their primitive tools, never making a mistake, working as their fancy might suggest, without any pattern, and quite at home in the maze of interlacing ornament.

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:In the forecourt a cast-metal nymph presides over a sham-bronze fountain.
  • 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:At the back of the shops, which lie lower than the street, we could see men trampling in vats all[Pg 261] day long; they were stamping and treading on old woollen shawls, fulling them to take off the shiny traces of wear, to sell them again as new goods.And suddenly, emerging from the ruins, we came on a Moslem street with high walls, windowless, and waving plumes of banyan and palm trees rising above the houses.

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:The same ubiquitous terminus on a sandy plain, remote from everything; then a drive jolting through bogs, and we reached the dirty, scattered town crowded with people who had collected round a sort of fair with booths for mountebanks, and roundabouts of wooden horses.Outside the palace is a large garden, devoid of shade, with pools of water bowered in flowers and shrubs that shelter myriads of singing birds. At the end of the park is a tank full of crocodiles. A keeper called the brutes, and they came up facing us in a row, their jaws open to catch the food which the Rajah amuses himself by throwing to them.
  • 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.
