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:"Did you ever publish it?" she asked, eagerly.

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:From Nara the party continued to Kioto, halting for dinner at Uji, which is the centre of an important tea district. Men and women were at work in the fields gathering the leaves from the plants, and other men and women were attending to the drying process which the gathered leaves were undergoing. They were spread out on matting, on paper, or on cloth, where they had the full force of the rays of the sun, and were frequently turned and stirred so as to have every part equally exposed to the solar heat. While the party was at Uji a shower came on, and then there was some very lively hurrying to and fro to save the tea from a wetting. During the afternoon the rain continued, and the rest of the ride to Kioto was not especially cheerful. Part of the route led along the banks of the river, which forms a navigable way for small boats between[Pg 288] the tea district and Osaka; and at one place, where the bank was broken, Frank had a narrow escape from an overturn into the water. The wheel of his little carriage sank into the soft earth and spilled him out, but, luckily, a friendly tree was in his grasp and saved him from falling down the steep slope of twenty feet or so. "A miss is as good as a mile," he remarked, as he brushed the mud from his clothes, and took his seat again in his vehicle.
  • 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:Top-side Galah!He had grown to detest the time after dinner passed in the plushy, painted drawing-room. Hitherto, in all these years of increasing prosperity, during which the conscious effort of his brain had been directed to business and money-making, he had not objected after the work of the day to pass a quiescent hour or two before his early bedtime giving half an ear to his wifes babble, which, with her brain thickened with refreshment, always reached its flood-tide of voluble incoherence now, giving half an eye to Alice with her industrious{291} needle. All the time a vague simmer of mercantile meditation gently occupied him; his mind, like some kitchen fire with the damper pushed in, kept itself just alight, smouldered and burned low, and Alices needle was but like the bars of the grate, and his wifes prattle the mild rumble of water in the boiler. It was all domestic and normal, in accordance with the general destiny of prosperous men in middle age. Indeed, he was luckier in some respects than the average, for there had always been for him his secret garden, the hortus inclusus, into which neither his family nor his business interests ever entered. Now even that had been invaded, Norahs catalogue had become to him the most precious of his books: she was like sunshine in his secret garden or like a bitter wind, something, anyhow, that got between him and his garden beds, while here in the drawing-room in the domestic hour after dinner the fact of her made itself even more insistently felt, for she turned Lady Keelings vapidities, to which hitherto he had been impervious, into an active stinging irritation, and even poor Alices industrious needle and the ever-growing pattern of Maltese crosses on Mr Silverdales slippers was like some monotonous recurring drip of water that set his nerves on edge. This was a pretty state of mind, he told himself, for a hardheaded business man of fifty, and yet even as with all the force of resolution that was in him he tried to find something{292} in his wifes remarks that could awake a relevant reasonable reply, some rebellious consciousness in his brain would only concern itself with counting on the pink clock the hours that lay between the present moment and nine oclock next morning. And then the pink clock melodiously announced on the Westminster chime that it was half past ten, and Alice put her needle into the middle of the last Maltese cross, and Lady Keeling waddled across the room and tapped the barometer, which a marble Diana held in her chaste hand, to see if the weather promised well for the bazaar to-morrow. The evening was over, and there would not be another for the next twenty-four hours.

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:"Are you looking at my clock?" enquired the Clockwork man, without altering his tone of speech. "I must apologise. I feel quite indecent."
  • 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.
