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:A revolution of a similar character took place in France within a month of the fall of Ripperda in Spain. The Duke of Bourbon had exhibited a gross incapacity for governing France under the young king. He was replaced by Cardinal Fleury, whose pacific designs harmonised with those of Walpole. Thus Fleury's accession to power only strengthened the English alliance with France. As for Spain, notwithstanding the fall of Ripperda, Philip continued the same course of policyclinging firmly to the Emperor, and employing Palm, the envoy of the Emperor in London, through bribery to the Duchess of Kendal and the king's Hanoverian Ministers, Bothmar and the rest, who were averse from the Treaty of Hanover, as in their estimation too exclusively calculated for British interests. They even produced a strong feeling of this kind in the mind of George, and they managed to detach the King of Prussia from the British alliance. On the other hand, Sweden was won over, by British gold and diplomacy, from Russian interests. The Dutch also, with their usual slowness, came into the Hanover Treaty. Several British fleets were at sea during the summer, watching the different points of possible attack. One under Admiral Wager sailed to the Baltic to overawe the Russians, which it did effectually. Admiral Jennings, with another squadron, having on board some land troops, scoured the coasts of Spain, kept the Spaniards in constant alarm, and returned home safe before winter. A third fleet, under Admiral Hosier, was not so fortunate. He was ordered to sail to the West Indies, and the shores of the Spanish Main, to obstruct or capture the galleons; but he was attacked off Porto Bello by the yellow fever, and lost a great number of his men.On the Rhine, the war was carried on quite into the winter. The King of Prussia did not stay longer than to witness the surrender of Mayence; he then hurried away to look after his new Polish territory, and left the army under the command of the Duke of Brunswick. Brunswick, in concert with Wurmser and his Austrians, attacked and drove the French from their lines at Weissenburg, took from them Lauter, and laid siege to Landau. Wurmser then advanced into Alsace, which the Germans claimed as their old rightful territory, and invested Strasburg. But the Convention Commissioners, St. Just and Lebas, defended the place vigorously. They called forces from all quarters; they terrified the people into obedience by the guillotine, Lebas saying that with a little guillotine and plenty of terror he could do anything. But he did not neglect to send for the gallant young Hoche, and put him at the head of the army. Wurmser was compelled to fall back; Hoche marched through the defiles of the Vosges, and, taking Wurmser by surprise, defeated him, made many prisoners, and captured a great part of Wurmser's cannon. In conjunction with Pichegru, Dessaix, and Michaud, he made a desperate attack, on the 26th of December, on the Austrians in the fortified lines of Weissenburg, whence they had so lately driven the French; but the Duke of Brunswick came to their aid, and enabled the Austrians to retire in order. Hoche again took possession of Weissenburg; the Austrians retreated across the Rhine, and the Duke of Brunswick and his Prussians fell back on Mayence. Once there, dissatisfied with the Prussian officers, he resigned his command, he and Wurmser parting with much mutual recrimination. Wurmser was not able long to retain Mayence; and the French not only regained all their old positions, before they retired to winter quarters, but Hoche crossed the lines and wintered in the Palatinate, the scene of so many French devastations in past wars. The French also repulsed the enemy on the Spanish and Sardinian frontiers.

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:[See larger version]
  • 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:

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.
