TWO:From Chin-kiang the steamer proceeded up the river. The account of what they saw was thus continued by the boys:
Classification by type of system
1natural circulation external heating pipe type
2natural circulation calandria type
3forced circulation type
4falling-film type
5rising film type
6jacket type
7coil type
Classification by method of operation
1single effect evaporator system
2multiple effect evaporator system
3auto-vapor mechanical compression system
4auto-vapor ejector compression system
5multistage flash system

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:My dear, he said, I am so glad you have let me come to you. You are in deep waters, poor girl.

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:You said, With Alice here too,. he said. Oblige me by telling me what you mean.Han-kow is a great centre of trade. Frequently the mouth of the Han is so crowded with junks that the river is entirely covered, and you may walk for hours by merely stepping from one boat to another. The upper Yang-tse and the Han bring down large quantities of tea, furs, silk, wax,[Pg 349] and other products, both for home use and for export. There are heavy exports of tea from Han-kow direct to England, and every year steamers go there to load with cargoes, which they take to London as rapidly as possible. Our friends were told that there was a large trade in brick tea, which was prepared for the Russian market; and as the boys were anxious to see the process of preparation, a visit to one of the factories was arranged. Frank made a note of what he saw and wrote it out as follows:
  • 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:He took his place at the wicket. The first ball was an easy one, and he managed to hit it fair and square to mid-on. Scarcely hoping for response, he called to the Clockwork man, and began to run. To his immense astonishment, the latter passed him half-way down the pitch, his legs jumping from side to side, his arms swinging round irresponsibly. It might be said that his run was merely an exaggeration of his walk. Arthur dumped his bat down quickly, and turned. As he looked up, on the return journey, he was puzzled by the fact that there was no sign of his partner. He paused and looked around him.
  • 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.
