Abstract: 358,220. Pasteurizing beer &c. GRAHAM, R. F., 29, St. Katherine's Way, Stepney, London. Sept. 5, 1930, No. 26550. [Class 49.] Apparatus for pasteurizing beer and other liquids and sauces, pickles and like materials enclosed in sealed containers comprises a carrier platform 3 for the containers 16 and a cam or other member 17 extending at an angle to the edge of the carrier 3 to engage the containers and cause them to move across the carrier 1 on relative movement of the carrier and cam, together with means for directing streams or a spray of pasteurizing liquid on the containers. In the construction described, the carrier 3, Figs. 1, 3 and 4, is ring- shaped and supported on rollers 4, 5 and rotated by the engagement, with a rack 6 thereon, of a pinion 7 on a shaft 8 driven through gearing 9, 10, 11 from an electric motor 12. The carrier 3 is constructed of plates 13, secured to a frame, between which are disposed plates 14 with narrow slots 15, Fig. 6, between. The plates 14 have their sides 14a bent down and are raised above the level of plates 13 so that they bear against the containers 15. Caps 60 may be slid into place over the plates 14 to reduce the space therebetween when smaller containers are being treated. The cam 17, Figs. 4 and 5, is supported by a stem 18 the upper end 19 of which slides in guides 20 extending across the carrier and'has bolted thereto a member 24 in which engages a screw 23 which, on operation of a clutch 31, can be driven through a star-wheel 30, engaged by a pin on the carrier, shaft 29 and gearing 27, 28 to move the cam 17 across the carrier. The cam 17 has one end adjacent the point at which the containers 16 are fed to the carrier and its length and angle are such that a container when in engagement therewith is moved across the carrier a distance equal to its diameter. In this manner a displacement of the containers across the carrier is obtained, the treated containers being removed at aperture 56. The containers may be fed to and removed from the carrier 3 automatically or by hand. The pasteurizing liquid is supplied from trays 32 having perforated buttons and divided into compartments 33 .. 36. Low temperature pasteurizing liquid, e.g. at 100-110‹ F., is supplied to the compartments 33, 34, which are interconnected, and 36 from a heater 37 through pipes 39, 40, 41, and perforated pipes 42, 43, the liquid being received by collecting tanks 48, 50, having connections 51, and returned through pipe 53 to the heater 37. Liquid at a higher temperature, e.g. 140‹ F., is supplied from a heater 38 to the compartments 35 through pipes 44, 45, 46 and perforated pipes 47, and is collected in a tank 49 and returned through a pipe 55 to the heater 38. Controlling valves are provided in the pipes. A greater number of compartments may if desired be employed together with other arrangements of piping, and mixing valves may be included. When it is desired to remove all the containers from the apparatus, the cam 17 is moved across the carrier 3 step-by-step by operating the screw 23, either by hand from the end 26 or by means of wheel 30 by operating clutch 31. The cam 17 may, in a modification, be disposed at the outer edge of carrier 3, the containers 16 being fed to the carrier at this edge and removed on the inside. Specification 329,733, [Class 49, Food &c.], is referred to.
