The invention relates to a continuous process for the preparation of a flavor or fragrance delivery system, wherein the presence of two heat exchangers operating respectively an evaporation and a cooling step, allow to optimize the quality and yield of the final product.

Continuous process for the incorpation of a flavor or fragrance ingredient or composition into a carbohydrate matrix

Disclosed is a mobile sealant material apparatus comprising a frame adapted for vehicular movement and bearing a scraped-surface, indirectly-heated jacketed vessel for housing heated, fluid sealant material Heated fluid heating media is heated in heating unit and pumped by a pump for recirculating through the jacket of the vessel in heat exchange relationship for heating sealant material housed therein and back to the media heating unit A sealant material outlet line is attached to the vessel for withdrawing heated sealant material from the vessel The sealant material in the outlet line also is being indirectly heated by the recirculated heating media from the media heating unit Finally, sealant material pump is attached to the outlet line for selectively applying heated sealant material, eg applying crack sealant to cracks in roadways

A product is continuously processed by passing it upwardly through a vertical heat exchange cylinder while continuously scraping the inner surface of the cylinder free of any product which may adhere thereto. This cylinder is surrounded by upper and lower outer cylinders to form upper and lower annular spaces through which respective heat exchange media are circulated, whereby the product can first be heated and then promptly cooled while passing through the heat exchange cylinder. To allow for different rates of expansion and contraction of the cylinders, a double expansion joint is provided between the two outer cylinders; and a temperature sensing device protrudes through this joint and into the heat exchange cylinder to measure the temperature of the product as it passes from the heating section to the cooling section of the heat exchange cylinder.

A system for making ice cream is provided herein. The system includes a pod, a whisking component, and a freezing component. The pod contains a mixture having powder mixture, flavoring liquid, and a stabilized fluid. The whisking component is attached to the pod and is configured to whisk the mixture and produce a whisked, aerated mixture. The freezing component freezes the whisked mixture and produces ice-cream. The whisking component includes a plurality of designs. In an embodiment, it is attached to the lid the pod or the body of the pod. In another embodiment, the whisking component may be a free moving whisk ball or a built in powder capsule.

sO', A vertically extending heat exchanger is provided in which an elongated dasher (16) is rotatably mounted within an upright cylindrical chamber (11). The exterior surface of the dasher coacts with the interior surface of the chamber to form a product flow passage (P). The opposite side of the chamber interior surface (H) is in contact with a heat exchange medium. The dasher is selectively movable longitudinally of the chamber between operative and inoperative modes. When in the operative mode, the dasher is fully assembled within the chamber and is supported at opposite ends by upper (12) and lower (13) endwall assemblies, the latter being mounted, respectively, on the upper and lower exterior end portions of the chamber. The dasher is movable to the inoperative mode when the lower endwall assembly is disassembled from the chamber and the dasher is lowered through the lower end portion of the chamber. The upper endwall assembly includes a static seal section (24) disposed in an encompassing nonrotating relation with an upwardly projecting axial segment of the dasher, and a dynamic seal section (48) encompassed by said static seal section and in sealing engagement therewith. The dynamic seal section encompasses the dasher axial segment and is rotatable therewith as a unit and moves longitudinally with the dasher when the latter is moved between operative and inoperative modes. The dasher axial segment has a portion protruding upwardly from the dynamic and static seal sections and is drivingly engaged by an exiernal drive unit only when the dasher is in the operative mode. The dasher axial segment portion automatically engages with the drive unit (47) when the dasher moves from the inoperative mode to the operative mode.

Vertically extending heat exchanger

Many products and other materials may be continuously processed by the vertically oriented swept surface heat exchanger described herein. The vertically oriented cylinder in which the processing takes place has an upper head assembly including a power drive and a lower head assembly containing a bearing in one embodiment and including a pump integral therewith in a second embodiment. A pump is included with the lower head assembly, for the preparation of ice cream or other aerated comestibles. A rotor extends the length of the unit and includes a drive shaft extending through an upper end plate to engage the power drive. This rotor supports wiping blades which sweep the inner surface of the cylinder. The wiping blades may include nozzles along the length thereof and are affixed to the end of blade pins which extend radially from the rotor. When removing or replacing a rotor in the heat exchange cylinder, the rotor is supported and moved vertically by a releasable latch mechanism until a hydraulic elevator integral with the heat exchanger is moved into place.
