In the apparatus shown a radiant heating zone 22 is formed above the one or more burners 37 said zone varying in axial extent according to the intensity of heating utilized. Above the radiant heating zone the stream 34 of combustion gases flows through the annular channel 21 constituting a convection input passage to a plenum chamber 38 with an exhast gas outlet 39. The air and combustion gases may pass through the apparatus in countercurrent (as shown) or in cocurrent relation. An annular baffle 35 defines with the sleeve portion 25 a convection output passage 36, the sleeve portion 25 being provided with fins 42 extending into the convection input and convection output passages. The fins 42 may comprise longitudinal fins (as shown), helical fins (Figs. 2 and 4) or pin fins (Fig. 3).

Title: Improvements in or relating to the treatment of milk
Inventor: WEARMOUTH WILLIAM GARDINER
IPC: A23L5/30
Filed: 1955-09-19
Abstract: Ultrasonic vibrations are used to render milk free from fat separation when thawed after storage in the frozen condition.  The vibrations may be produced by a vibrating crystal and transmitted by means of a probe inserted into the milk.  The preferred range of frequency is 0.75-2.0 megacycles/sec.; using a power of 150-200 watts per gallon of milk, treatment times of 5-2 minutes are effective.ALSO:Milk free from fat separation when thawed after storage is obtained by subjecting the milk to vibrations at ultrasonic frequency and then freezing within an hour.  According to an example, milk is pasteurized and immediately treated for 5 minutes with ultrasonic vibrations at 1-1.3 megacycles/sec. and a power of 150 watts per gallon of milk; the treated milk is packed in polythene containers which are then heat-sealed and immersed in a refrigerant liquid at 4-5 DEG  F. so that complete freezing is achieved with 40 minutes.
