Abstract

1,075,807. Evaporators; film-type. HENRY BALFOUR & CO. Ltd. Oct. 5, 1966 [Oct. 27, 1965], No. 45413/65. Addition to 1,038,204. Heading B1B. In an evaporator wherein liquid is evaporated from a liquid-film spread on the internal surface of an externally-heated cylinder shown in part by reference 36), the liquid being spread on the urface by curved wiper elements w which are loosely attached to a otor, in the manner laimed in Specificaion No. 1,038,204, the operative face of each element is recessed vith grooves G, the ide walls g of which are inclined to the longitudinal axis of the element. The line of contact WL of each element with the heated wall of the evaporator may be either inclined to the rotor axis RA, or the line of contact may be parallel to RA.
