摘要： PURPOSE:To make installation cost and running cost small and to evaporate and concentrate water solution of a large boiling point rise by detecting the feed quantity of liquid to be concentrated to a heat exchanger and circulating the liquid to be concentrated from a liquid chamber through the heat exchanger to replenish the required quantity only in case of shortage of the feed quantity of the liquid to be concentrated. CONSTITUTION:Liquid to be concentrated heated and concentrated by heat exchangers 1a, 2a is evaporated in liquid chambers 1b, 2b of evaporator 1, 2 to separate evaporated steam. At this time, the feed quantity of the liquid to be concentrated to the heat exchangers 1a, 1b is detected by detecting means 9, 13 and if the detected quantity does not meet the one required for performing the prescribed heat exchange, the liquid to be concentrated in the liquid chambers 1b, 2b are circulated through the heat exchangers 1a, 2a by circulating means 10, 11, 14, 15 so that the feed quantity of the liquid to be circulated to the heat exchangers 1a, 1b may be the one required for performing the prescribed heat exchange.

摘要： PURPOSE:An electric motor and a steam turbine as an auxiliary are used to drive the mechanical compressor in an evaporative concentrator for dry milk production the exhaust steam from the turbine is used in sterilization and drying to produce powdered milk with largely saved power costs. CONSTITUTION:The evaporative concentrator 1 in the powdered milk production is composed of the electric motor 1, a steam turbine 11 which is concentrically connected with the motor 1 and is used as an auxiliary and the evaporator 2 and the vapor 5 from the evaporator 2 is sucked, raised in temperature and pressure and allowed to return back through pipe 6 into the evaporator 2, thus the fresh milk 8 which is taken out of the sterilizer 8 is evaporated and sent into the drier 10. The back pressure 17 of the steam turbine is detected, high- pressure steam 12 is controlled in its feed rate and pressure with the pressure controller 16 and a regulation valve 18 and fed into the turbine 11 in a needed amount. At the same time, the electric power corresponding to the remaining energy for the compressor 3 is fed to the electric motor 4 to drive the compressor 3, while the low-pressure steam after driving the turbine 11 is divided into two, one is sent to the sterilizer 7 to sterilize the fresh milk and the other is sent to the drier to dry concentrated milk into powdered milk.

摘要： PROBLEM TO BE SOLVED: To obtain further higher energy-saving effect by a method wherein steam generated from a reboiler is compressed to be supplied to a distillation tower, a reboiler is heated with the steam rising in the distillation tower, and simultaneously reflux is generated in the distillation tower to execute distillation operation. SOLUTION: Mixed solution in which a raw material is introduced at a specific proportion into a tower bottom solution of a distillation tower 5 and a reboiler part 4, is supplied to an upper part in a pipe (the reboiling part) 4 from a solution inlet 8, and steam generated from an inside of the pipe (the reboiling part) 4 is pressurized with a compresser 20 to be supplied to a tower bottom of an outside of the pipe (a distillation tower part) 5 from a steam inlet for outside pipe 10. Thereby, the outside of the pipe (the distillation part) 5 is operated at a pressure higher than that of the inside of the pipe (the reboiler part) 4, the inside of the pipe (reboiling part) 4 is heated with steam rising in the outside of the pipe (distillation part) 5, and reflux is generated in the outside of the pipe (the distillation part) 5 to execute specific distillation operation. Therefore, energy required for compression is extremely reduced, and distillation can be efficiently executed.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a fiber board which bears a least drying load in a raw material stage and a least drying load in a molding step when the fiber board is manufactured in the dry mode and enables installation cost and running cost to be reduced. SOLUTION: An aqueous polyisocyanate compound solution is added to a raw material used paper (split fibber) to obtain a raw material for the fiber board with a water content of 10-30 wt.% and a dry base polyisocyanate compound content of 5-15 wt.%. This raw material for the fiber board is heated and clamped in a hot press step until the polyisocyanate compound MDI) is cured and the water content is 5-10 wt.%. Thus the raw material is molded into the fiber board with a specific gravity of 0.6-0.8. In the hot press step, a clamping removal step to remove the pressing of a hotplate or lower a pressure to a level below a specified pressure is introduced into an interval between the clamping steps to press the hotplate to the raw material for the fiber board at a specified pressure.
