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.

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:Sir Henry Hardinge, the new Governor-General of India, whom Sir Robert Peel recommended to the Board of Control, had been in the army since he was thirteen years of age. He had followed Wellington through all the battles of the Peninsular war, and had won all the military glory that could be desired, so that he was not likely to follow the example of Lord Ellenborough in opening fresh fields for the gathering of laurels in India. The Chairman of the East India Company, giving him instructions on his departure, cautioned him against following the example of Lord Ellenborough in appointing military officers as administrators in preference to the civil servants of the Crown. He reminded him that the members of the Civil Service were educated with a special view to the important duties of civil administration, upon the upright and intelligent performance of which so much of the happiness of the people depended. He expressed a hope that he would appreciate justly the eminent qualities of the civil servants of India; and that he would act towards the Sepoys with every degree of consideration and indulgence, compatible with the maintenance of order and obedience. He urged that his policy should be essentially pacific, and should tend to the development of the internal resources of the country, while endeavouring to improve the condition of the finances.CHAPTER II. THE REIGN OF GEORGE III. (continued).
  • 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 year 1743 opened with a mighty struggle on the subject of gin. In 1736, as we have seen, the awful increase of drunkenness, which was attributed to the cheapness of gin, induced a majority of the House of Commons to pass an Act levying twenty shillings a gallon duty upon the liquor, and charging every vendor of it fifty pounds per annum for a licence. Walpole at the time declared that such an attempt to place gin beyond the reach of the poor consumers would fail; that it would fail equally as a source of revenue, for it would lead to wholesale smuggling and every possible evasion of the law. The event had proved Walpole only too correct in his prognostications. So far from checking the use of gin, the Act had stimulated it enormously. The licences, so preposterously high, were wholly neglected; no duty was paid, yet the destructive liquid was sold at every street corner. Ministers now saw that, by attempting too much, every thing in this case had been lost. They were sacrificing the revenues only to sacrifice the well-being of the people. They determined, therefore, to reduce the licences from fifty pounds to one pound per annum, and at the same time to retain a moderate duty on the liquor. By this means the fatal compound would remain much at the same price, but the vendors would be induced to take out licences, and the revenues would be greatly improved, whilst the whole sale of the article would be more under the restraints of law and police. A Bill was framed on these principles, and passed rapidly through the Commons; but in the Lords it encountered a determined opposition. It was, however, carried entire, and, says Smollett, "we cannot help averring that it has not been attended with those dismal consequences which the Lords in the Opposition foretold."

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:The next person to attempt the impossible in the vain endeavour to keep the vessel of the old French monarchy afloat with all its leaks and rottenness, was the Archbishop of Toulouse, Lomnie de Brienne. He had vigorously opposed Calonne; but there was no way of raising the necessary revenue but to adopt some of the very proposals of Calonne, and tax the privileged classes, or to attempt to draw something still from the exhausted people. As the less difficult experiment of the two, he was compelled to cast his eyes towards the property of the nobles and the Church; but he found the nobles and the clergy as ready to sacrifice him as they had been to sacrifice Calonne. When one or two of the more pliant or more enlightened members of those classes ventured to remark on the vast amount of untaxed property, and particularly of tithes, there was an actual tempest of fury raised. Tithes were declared to be the voluntary offerings of the piety of the faithful, and therefore not to be touched. As further loans were out of the question, some one ventured to assert that the only means of solving the difficulty was to assemble the States General. "You would convoke the States General?" said the Minister in consternation. "Yes," replied Lafayette, who was bent on revolutionising France, as he had helped to revolutionise America"yes, and something more than that!" These words were taken down as most exceptionable and dangerous. All that the Assembly of Notables could be brought to do was to confirm the abolition of the corve, and to pass a stamp act. They would not move a step further, and they were dismissed by the king on the 25th of May, 1787. The Parliament, or Chief Court of Justice, adopted a similar course, and it also was dismissed. The king then promulgated a new constitution, but it fell hopelessly to the ground.
  • 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.
