摘要:
A modular self-dispensing ice cream maker includes an open-ended chilling container which encloses a mixing chamber in which a dasher is mounted for bidirectional rotation. The container includes a cylindrical chamber which is at least partially filled with freezable solution for cooling ice cream ingredients. The open end of the mixing chamber receives a cover having a dispensing outlet. The ice cream maker is adapted for orientation in mixing and dispensing modes in which the container is respectively supported in generally vertical and horizontal orientations. The dasher includes blades configured to scrape an inner container wall during rotation in a first direction for mixing ice cream. Reverse rotation of the dasher advances ice cream toward the cover for dispensing.

The invention concerns a process to perform the alimentary mixtures pasteurization in apparatuses of the type comprising a refrigerating circuit provided with compressor, condenser, expansion valve and evaporator and at least one vessel to contain the alimentary mixture under conditions of thermal exchange with at least one coil. The process according to the invention is characterized in that it comprises the steps of:(a) heating the mixture contained in at least one vessel connecting the components of the refrigerating circuit and the coil to each other in the following order: compressor, coil, condenser, expansion valve, evaporator, compressor(b) cooling the mixture contained in the vessel connecting the components of the refrigerating circuit and the coil to each other in the following order: compressor, condenser, expansion valve, coil evaporator, compressor.The invention also comprises a pasteurizing apparatus to perform the process; said apparatus, of the aforesaid type, is characterized in that said evaporator of the refrigerating circuit comprises valve means to deviate the refrigeration fluid capable of connecting to the refrigerating circuit itself the coil of at least one vessel upstream the condenser or downstream the evaporator to heat or to cool respectively the content of the vessel itself.
摘要:
A household ice-cream machine has an annular container in which a blade driven by a geared motor is rotatable, the container being releasably supported within an annular vessel so as to define an interspace containing a measured quantity of a liquid with a low freezing point.The cooling system of the ice-cream machine includes an evaporator coil disposed in favorable heat-exchange relationship with the liquid in the said interspace.

A machine for making ice-cream and similar cold products is described, which has a freezing container insertable in and removable from a substantially cylindrical cooling chamber. The chamber is elastically-deformable and has a circular cross-section that is not completely closed on itself due to the presence of a passage. The passage is closed by a pair of shields and by a substantially bellows portion of elastically yielding and thermally insulating material. In this manner, a better thermal efficiency of the machine is obtained.

An ice cream-making apparatus is described wherein the freezer vessel is engageable in and disengageable from a cooling basket comprising two half-shell-like parts openable to receive the freezer vessel and to be clamped thereon. The cooling coil forming the basket is resiliently yieldable radially of the actual basket.In an apparatus of this kind effective contact is always ensured between the cooling coil and the freezer vessel, so that efficiency is very high.

A comestible freezer has a freezing barrel with a cold wall, an input end and an output end and a feeder therewithin having a ribbon auger flight helix and a stationary blending bar within the helix. A portion of the ribbon auger flight helix has an outward twist or skew diverging from a radial plane through the axis of the helix and outwardly toward the barrel wall whereby to exert a component of thrust on the comestible toward the cold wall. A portion of the ribbon also has an inward twist or skew diverging from the radial plane and inwardly toward the blending bar whereby to exert a component of thrust on the comestible toward the bar.

A torque-transmitting, torque-sensing system has a first rotatable shaft which can be shifted radially in two orthogonally-displaced directions to be precisely concentric with a second rotatable shaft, has a first coupling element which is rotatable with but which is movable axially relative to one of those rotatable shafts, has a biasing means which urges the first coupling element for movement axially in one direction relative to the one rotatable shaft, has a second coupling element which is rotatable with the other rotatable shaft, and has a surface on one of those coupling elements which coacts with a complementary surface on the other of those coupling elements to enable those coupling elements to transmit torque from that rotatable shaft which is the driving shaft to that rotatable shaft which is the driven shaft while permitting the first coupling element to respond to a predetermined increase in rotation resistance of the driven shaft to move axially in the opposite direction relative to the one rotatable shaft.
