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:Another grievance was the Ellton baby. Felipa adored it, and for no reason that he could formulate, he did not wish her to. He wanted a child of his own. Altogether he was not so easy to get on with as he had been. She did not see why. Being altogether sweet-humored and cheerful herself, she looked[Pg 182] for sweet humor and cheerfulness in him, and was more and more often disappointed. Not that he was ever once guilty of even a quick burst of ill temper. It would have been a relief.

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:Just at the edge of the rock stream there was an abandoned cabin built of small stones. Whatever sort of roof it had had in the beginning was now gone altogether, and the cabin itself was tumbling down. Through the doorway where there was no door, there showed a blackened fireplace. Once when a party from the post had been taking the two days' drive to the railroad, they had stopped here, and had lunched in the cabin. Landor remembered it now, and glanced at the place where Felipa had reclined in the shade of the walls, upon the leather cushion of the ambulance seat. She very rarely could be moved to sing, though she had a sweet, plaintive voice of small volume; but this time she had raised her tin mug of beer and, looking up to the blue sky, had launched into the "Last Carouse," in a spirit of light mockery that fitted with it well, changing the words a little to the scene.[Pg 279]Cairness, talking to one of the other men, who was mending a halter, watched him, and recalled the youth in spotless white whom he had last seen lounging on the deck of an Oriental liner and refusing to join the sports committee in any such hard labor as getting up a cricket match. It was cooler here in the Arizona mountains, to be sure; but it was an open question if life were as well worth living.
  • 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:Felipa held out her hand and showed a little brown bird that struggled feebly. She explained that its leg was broken, and he drew back instinctively. There was not a trace of softness or pity in her sweet voice. Then he took the bird in his own big hand and asked her how it had happened. "I did it with an arrow," said Diana, unslinging her quiver, which was a barbaric affair of mountain-lion skin, red flannel, and beads.Landor said that he had put in a requisition for kippered mackerel and anchovy paste, and that the commissary was running down so that one got nothing fit to eat. He was in an unpleasant frame of mind, and his first lieutenant, who messed with him, pulled apart a broiled quail that lay, brown and juicy, on its couch of toast and cress, and asked wherein lay the use of taking thought of what you should eat. "Every prospect is vile, and man is worse, and the sooner heaven sends release the better. What is there in a life like this? Six weeks from the nearest approach to civilization, malaria in the air by night and fire by day. Even Mrs. Landor is showing it."

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:"How do you know this?"
  • 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.
