摘要： PURPOSE:To surely remove the solvent or the low boiling point component in the product solution and to attain the improvement of the product recovery rate by heat-evaporating the solvent with a heat evaporator, subsequently discharging into a tank, etc., at a lower pressure than a pressure in the heating evaporator and removing the solvent. CONSTITUTION:The hexane solution of a high molecular compound is steam- heated in the centrifugal film evaporator 1 under an atmospheric pressure and a residual rate of hexane in the high molecular compound is reduced and it is discharged into a evacuated tank 11 with an intermediate pump. As a result, the solvent or the low boiling point component in the product solution of the high boiling point compound or the high molecular compound, etc., is surely removed and the major part of the solvent or low boiling point component can be condensed in a high pressure state, so the recovery rate is high and the total cost can become advantageous.

In a sludge decomposition tank 12, hydrochloric acid 13 is added to the magnetic flocs 10 to be stirred, thereby decomposing the magnetic flocs. The treated liquid containing the decomposed magnetic flocs is subjected to gravity separation in a sedimentation tank 14, and the treated liquid containing magnetic powder and the coagulant is recycled.

摘要： PROBLEM TO BE SOLVED: To provide a movable-vane thin-film evaporator by which the abrasion powder of the material of the sliding part of a vane is prevented from being mixed in a processing soln. to contaminate it. SOLUTION: This evaporator is composed of a groove 11 by which the abrasion powder generated from a sliding part is collected and not leaked outside (on the processing-soln. side) and a guide 12 into which the abrasion powder is easily introduced. Since the abrasion powder, if generated, is collected in the groove and not leaked outside, a pure treated material which is not contaminated is obtained.

摘要： PURPOSE:To prepare a concentrated soap with optimum residual moisture content and properties for the production of a solid soap, by using a centrifugal thin-film evaporator in producing a soap by drying a neat soap. CONSTITUTION:Raw mterial is fed into a centrifugal thin-film evaporator 1 under atmospheric or elevated pressure and concentrated by externally heating with steam. The concentrated material is then flushed into a bottom tank 2 in a vacuum to effect self-evaporation. Since the concentration is performed in two steps, i.e., under a pressure and through self-evaporation by flushing, the throughput of the material per unit heat transfer area of the evaporator is increased to thereby provide an economic advantage. In addition, because of the temperature fall due to self-evaporation, the concentrate is obtained in a solidified state and can be preserved in a state in which it is suitable for the production of soap.

摘要： PURPOSE:To remove liquid to be treated (high viscous liquid) attached to and retained on the inside of a vessel and the upper part of a screw and to prevent quality deterioration by installing a spiral screw without an axis and a shank over an extruding screw. CONSTITUTION:A sbiral lead-in screw 3 having a small clearance with the conical part of the vessel 1 is connected in the axial direction to a rotation axis 6 of an extrusion screw 4. The lead-in screw 3 has no central axis nor central part. Liquid 2 to be treated falling from a centrifugal thin film evaporator flows down within a falling range 7 of the liquid 2 above the lead-in screw 3 and flows down on the lead-in screw 3 and the conical part of the vessel 1. The liquid 2 is pushed out to the peripheral part of centrifugal force due to the rotation of the lead-in screw 3 and then pushed downward by the lead-in screw 3. The liquid pushed downward is led to an extruding screw 4 where its pressure is raised to discharge it to the outside of the system through a discharge nozzle 5.
