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:The man, still running, dodged from the road and started across country. Cairness wheeled and followed him. It was open ground, with not so much as a scrub oak or a rock in sight. The thick darkness offered the only chance of escape. But Cairness had chased yearlings in nights as black, and had brought them back to the herd. Down by the creek where the trees were thick, there would have been a good chance for escape, almost a certainty indeed, but there was little here. The man dodged again. It was just to that very thing that the pony had been trained. Habit got the better of stampede with it. It, too, dodged sharply.

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:She laughed scornfully. "It ain't me that asked them to take me in," she said; "I'm as glad to go as they are to have me." She wore a calico wrapper that Cairness had bought for her, and other garments that had been gathered together in the town. Now she put a battered sombrero on her head, and told him she was ready.
  • 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:It was not until they all, from the commandant down to the recruits of Landor's troop, came to say good-by that she felt the straining and cutting of the strong tie of the service, which never quite breaks though it be stretched over rough and long years and almost [Pg 291]forgotten. The post blacksmith to whom she had been kind during an illness, the forlorn sickly little laundress whose baby she had eased in dying, the baker to whose motherless child she had been good—all came crowding up the steps. They were sincerely sorry to have her go. She had been generous and possessed of that charity which is more than faith or hope. It was the good-bys of Landor's men that were the hardest for her. He had been proud of his troop, and it had been devoted to him. She broke down utterly and cried when it came to them, and tears were as hard for her as for a man. But with the officers and their women, it rose up between her and them that they would so shortly despise and condemn her, that they would not touch her hands could they but know her thoughts.They glanced sideways at the big Englishman, who appeared to be one of themselves, and at the little minister. On him, more especially on his hat, their eyes rested threateningly. They had heard of him before, most of them. They answered his genial greeting surlily, but he was quite unruffled. He beamed upon the room as he seated himself at one of the tables and ordered supper, for which, in obedience to a dirty sign upon the wall, he paid in advance.

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:
  • 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.
