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:In the middle of the town, which consists entirely of small houses carved from top to bottom, are two massive towers, joined by the remains of the thick wall that formerly enclosed the immensity of the sultan's palace and its outbuildings. The towers now serve as prisons; the stone lattice which screened the private rooms has been replaced by iron bars, the last traces of ornamentation covered up with fresh plaster. Behind the wall the ancient garden, kept green of old by legions of gardeners, is a mere desert of dust; a mausoleum in the middle, transformed into a court of justice, displays all the perfection of Indian art in two pointed windows carved and pierced in imitation of twining and interlaced branches; marvels of delicacy and grace left intact through centuries of vandalism.Captain McT's orderly appeared as soon as we stirred in the morning, shouldering armsthe "arm" an umbrella which the authorities allow as a privilege off duty to the Ghoorkhas, men from the high plateaux, who are very sensitive to sunstroke, and who wear only a cap without a pugaree. The umbrella solemnly resting against his right shoulder, this worthy stood at attention, serious and motionless, and very uprighta quaint figure, his age impossible to guess, with his Mongolian face, his little slits of eyes, and his figure, in spite of his military squareness, rather too pliant in the yellow khaki uniform.

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:At a goldsmith's I stood to watch a native making a silver box. He had no pattern, no design drawn on the surface, but he chased it with incredible confidence, and all his tools were shapeless iron pegs that looked like nails: first a circle round the box, and then letters and flowers outlined with a firm touch that bit into the metal. He had no bench, no shopnothing. He sat at work on the threshold of his stall, would pause to chat or to look at something, and then, still talking, went on with his business, finishing it quite simply at once without any retouching.
  • 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:The heat to-day has suddenly become stifling; the low clouds veil the colourless sun, and the flowers, which yesterday were still lovely, are now[Pg 278] withered and pallid, and only give out their scent in the evening, when it is cool again.

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:Wide strands of golden sand; here and there among the rice-fields the palms and bamboos are less crowded. In the moist air, that grows hotter and hotter, the daylight is blinding, hardly tolerable through the blue glass of the windows. Scorched, russet rocks stand up from the short grass, tremulous in the noontide heat. The cattle, the very birds, silent and motionless, have sought shelter in the shade; all the people have gone within doors. And then, towards evening, in an oasis of gigantic trees, amid bamboos and feathery reeds, behold the huge temples of Madura, in sharp outline against a rosy sky.
  • 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.
