摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing substances to be removed from fluid and a sludge separation and recovery device which can recover recyclable materials from sludge and reduce the operation costs of the apparatus.
SOLUTION: A magnetic material and a coagulant are continuously supplied to raw water 1 to be stirred, thereby generating magnetic flocs 10. The magnetic flocs 10 are collected in a sludge recovery tank 11 by a magnetic separation and purification device having a mesh 6' having an aperture through which the magnetic flocs 10 cannot pass, a magnetic field generation means 8 for magnetically attracting the magnetic flocs 10, and a scraper 9 for recovering the flocs. 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 provide a method for producing SHOCHU (a popular spirit made from a sweet potato or rice) good in flavor by which furtural causing the deterioration in quality is prevented from producing by instantaneous heating and evaporation. CONSTITUTION: This method for producing SHOCHU is to use a centrifugal thin-film evaporator capable of carrying out the instantaneous heating and evaporation in the former stage and use a distillation column in the latter stage. The apparatus is operated under conditions of =100Torr operating pressure and =100 deg.C heating temperature. Thereby, impurities can efficiently be removed and ingredients deteriorating the quality are prevented from producing to afford the SHOCHU good in flavor.

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.

摘要： PURPOSE:To provide the subject device having a specified structure, capable of sampling a liquid having the same physical properties as those of a liquid in a vessel during operation from the vessel in an airtight state without interference with airtightness and operation and capable of washing remaining liquid in the valve. CONSTITUTION:An airtight valve 3 designed so as to keep the airtightness of the inside of a vessel 1 and to enable passage of a very small quantity of liquid and a grooved screw valve 6 capable of sending a very small quantity of liquid are initially attached in a valve box 2 so that they may be independently operated. The liquid in the vessel is allowed to flow into the grooved screw valve 6 by opening the airtight valve 3 and the liquid is then discharged through the outer periphery part of the grooved screw valve 6 to the outside of the system by turning the grooved screw valve 6. The shape of the grooved screw valve 6 is preferably a (reverse) cone shape or a cylindrical shape.
