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:

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:The South Sea Company, with a folly of which extreme greed only is capable, endeavoured to put down these rival schemes and obtained an order from the Lords Justices and writs of scire facias against several of these new bubbles. It was like raising a wind to blow away the bubbles, forgetting that their own was a bubble too, and would go with them. The moment that the people began to distrust one they distrusted all. The panic became as great as the mania had been. The South Sea stock dropped in less than a month from one thousand to below six hundred. There was a simultaneous rush to sell out, and the shares must have sunk instantly to nil but for the gigantic exertions of the Company to raise money and buy in. The relief, however, was but temporary. The bankers and pawnbrokers who had advanced money on scrip broke and fled; merchants, goldsmiths, and speculators rushed away after them. Walpole was summoned in haste from Haughton to devise some means of staying the panic. He endeavoured to get the Bank of England to circulate three millions of South Sea bonds for a year; but the Bank, seeing that the case was desperate, declined it. This was decisive. The rage and despair of the swarming dupes were indescribable. They heaped[48] execrations not only on the South Sea Company, but on Ministers, the king, his mistresses, and the Royal Family, who had all been deep in the affair, and who had taken good care of themselves. George landed at Margate on the 9th of November, soon after which the South Sea stock fell to one hundred and thirty-five. On the 8th of December Parliament met, and promptly began to investigate the scandal.The news had the most instant effect across the Channel. All hesitation on the part of the French Court to enter into the treaty with the United States disappeared. The American Commissioners, Franklin, Deane, and Lee, were informed that the King of France was ready to make a treaty, claiming no advantage whatever, except that of trade with the States. It was intimated that this proceeding would, in all probability, involve France in a war with Great Britain, but that she would claim no indemnity on that score. The only condition for which she positively stipulated was, that America should, under no temptations, give up its independence, or return under the dominion of England. The two kingdoms were to make common cause, and assist each other against the common enemy. The Americans were to endeavour to make themselves masters of all the British territories that they could, and retain them as their rightful acquisition; the French to obtain whatever islands they could in the West Indies, and retain them. France did not venture to seek back the Canadas or Nova Scotia, well knowing that the Americans would not consent to have them there as neighbours. Neither country was to make peace with England without the other. Lee was to continue at Paris as the first American Ambassador there, and the treaty was to continue some weeks a secret, in order to obtain, if possible, the accession of Spain to it, which, however, they could not do then.
  • 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:[See larger version]Among the resources of Great Britain to which she is mainly indebted for her pre-eminence as a manufacturing nation, and without which she would not have been able to make anything like the progress she has made, or to bid defiance to foreign competition as she may always do, are her mines of coal and iron. The total produce of all the British ironworks was found, after a careful estimate, to be, in 1823, 442,066 tons; in 1825, 581,367 tons; in 1828, 653,417, and in 1830, 702,584 tons. In 1844 the quantity reached 1,500,000 tons. The quantity of tin produced in England in 1820 was 3,578 tons; in 1834 it was 4,000 tons. In addition to the quantities used at home, there was a considerable exportation of tin plates, the value of which in 1820 was about 161,000, and in 1840 it was more than 360,000. The produce of the copper mines in Cornwall was much greater than that of the tin mines; for while in 1820 it was only 7,364 tons, it had increased in 1840 to 11,000 tons. The increase during 60 years had been threefold, and the value annually raised exceeded 1,000,000 sterling. In the year 1820 the quantity of coals shipped from the port of Newcastle was more than 2,000,000 tons. In the year 1840 it had increased to nearly 3,000,000. From the port of Sunderland the quantity shipped in 1820 was considerably more than 1,000,000. In 1840 it was 1,300,000 tons. Large quantities were also shipped from the port of Stockton. The chief coal districts have naturally become the chief manufacturing districts; and as the coal is on the spot, it is impossible to estimate the quantities consumed in working the factories in Lancashire, the West Riding of Yorkshire, Nottingham, Derby, Birmingham, Wolverhampton, Leicester, Coventry, and Staffordshire. The town of Sheffield alone, it was estimated in 1835, required for manufacturing purposes about 515,000 tons of coals. Dr. Buckland, in his address to the Geological Society, in 1840, stated that "the average value of the annual produce of the mines of the British islands amounts to the enormous sum of 20,000,000, of which about 8,000,000 arises from iron, and 9,000,000 from coals."

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:FROM THE PAINTING BY F. X. WINTERHALTER IN THE NATIONAL GALLERY.[See larger version]
  • 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.
