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:It is of interest to trace some of the practical results which followed Beccarias treatise during the thirty years that he lived after its publication; that is, from the year 1764 to 1794.The aim of punishment is not to torment sensitive beings.

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:
  • 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 same may be said, though for a different reason, where there are several accomplices of a crime, not all of them its immediate perpetrators. When several men join together in an undertaking, the greater its[163] risk is, the more will they seek to make it equal for all of them; the more difficult it will be, therefore, to find one of them who will be willing to put the deed into execution, if he thereby incurs a greater risk than that incurred by his accomplices. The only exception would be where the perpetrator received a fixed reward, for then, the perpetrator having a compensation for his greater risk, the punishment should be equalised between him and his accomplices. Such reflections may appear too metaphysical to whosoever does not consider that it is of the utmost advantage for the laws to afford as few grounds of agreement as possible between companions in crime.Why then did Pietro Verri not write it himself? The answer would seem to be, out of deference for the position and opinions of his father. It was some time later that Gabriel defended the use of torture in the Milanese Senate, and Pietro wrote a work on torture which he did not publish in his fathers lifetime. It was probably due also to the fathers position that Alessandro held his office of Protector of the Prisoners, so that there were obvious reasons which prevented either brother from undertaking the work in question.

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:CHAPTER XI. OATHS.
  • 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.
