Abstract

363,071. Pasteurizing milk &c. ENOCK, A. G., Dutch House, Raglan Gardens, Wembley Park, . Middlesex, and MORTON & CO., Ltd., R., Trent Works, Burton-on-Trent. Nov. 4, 1930, No. 33071. [Class 49.] In pasteurizing and subsequently cooling milk or other liquids enclosed in bottles or other containers by submersion in heating and then in cooling liquids, covers are provided to imprison air above the sealing discs or lightly attached caps of the bottles &c. during the treatment so that air can leak into the bottle during the cooling operation and the discs &c. are protected from contact with the liquid. In one form, Figs. 1 and 4, the bottles A are carried through the treatment apparatus by a conveyer G which carries on transverse rods air bells B in which the necks of the bottles are secured by springs b<1>. The bottles may be fed by hand or automatically to the bells, and are removed by hand or automatically by means of a rocking bar M which tilts the bottles on one side and a rocking bar M<1> which tilts them in the reverse direction and releases them, the bottles sliding on .to a pad mon an oscillating rod m<1> which pushes them on to a conveyer m<2>. The bells B may have springs b<1>, Fig. 9, which can be spread apart to effect release by pressing the bottle upwards and thus pushing up a disc b<4>. In other forms, Figs. 10 and 13 (not shown), the bells B are made to enclose the bottles, and have open bottoms and their lower portions, perforated and normally oval in shape to retain the bottle but capable of being squeezed to round shape to release it, or having a hinged or pivoted bar at the bottom to support the bottle. In another form, Fig. 7, bottle carriers E are mounted on transverse bars e carried by the conveyer and have springs b<1> which are made to engage and release the bottles by pushing on or removing detachable bells B. A hook, Fig. 3 (not shown), which engages hooks at the tops of the bells B and is operated by a cam or eccentric may be employed to release the treated bottle automatically from the conveyer. The bottles may be suspended by their necks by means of two parallel bars B<2>, Fig. 20, having an insertion opening for the bottle necks and enclosed by a bell B. The bottles may be carried through the apparatus in a crate F, Fig. 23, to which is attached a cover B<4> formed with air bells B, one for each bottle. In a modification, Fig. 25, one air bell B covers and carries a, group of crates which are supported therefrom by catches h<1>, the crates being released by moving levers h<2>, which operate toggle levers h attached to the catches h<1>. In other forms of the apparatus, a cap D, Fig. 14, having an air space d and a rim d<1>, which engages the neck of the bottle forming an air and liquid-tight joint, is provided to cover the closure disc a, the cap having a serrated lower edge so that air can leak from the chamber d past the disc a on cooling. Each cap D may be provided with springs b<1> which engage and support the bottle A, or cages, Figs. 15 and 19 (not shown), may be employed, for supporting one or more bottles, in which the caps are pressed into contact with the tops of the bottles by spring means attached to the caps or to the bottom supports for the bottles.
