Abstract:
The invention describes a low temperature extrusion process and a respective device for an energy-optimized and viscosity-adapted microstructuring of frozen aerated systems like ice cream. Therewith a very finely dispersed microstructure is reached under optimized balance of viscous friction based mechanical energy dissipation and transfer of dissipation heat and additional phase transition (freezing) heat to a refrigerant up to very high frozen water fraction at very low temperatures. With this new process and device aerated masses are continuously frozen and optimally micro-structured under minimized/optimized mechanical energy input. The microstructure of this-like treated masses supports on the one hand preferred rheological properties which lead to improved shaping, portioning and scooping properties, even at very low temperatures, and on the other hand leads to an improved shelf life (heat shock stability) and mouth feel (e.g. creaminess, melting behavior).
Abstract:
A method for freezing a food product comprising the steps of: (a) contacting the food product with a freezing surface, the freezing surface having a temperature of from −10° C. to −50° C.; and (b) removing the food product from the freezing surface, characterised in that in step (a) a layer of a frozen aqueous solution is present between the food product and the freezing surface, the solution having a Tg′ below −60° C. and a solute concentration of from 0.001 to 20% by weight.
Abstract:
A plant for continuous flow freezing of edible ice products is built up in a freezing section (100) with a tray conveyor (8), the drive chain of which leads trays carrying the items to be frozen from an entrance to the freezing section (100) and around a conveyor support frame (10), and where by means of at least one fan or blower (26), a flow of freezing air from at least one freezing aggregate (24) is brought to pass across the items to be frozen during passage along the conveyor support frame (10). With the view to achieving a maximum speed of the flow of freezing air in relation tot he average speed of the air flow across the items, and compact construction while still providing easy access for maintenance and cleaning, there is disclosed an embodiment comprising at least two conveyor support frames (10) placed at the side of each other, and where the frames (10) in all comprise at least one freezing aggregate (24) and at least one fan or blower (26) for driving the flow of freezing air.
Abstract:
An ice cream machine for cooling liquid ice cream into frozen ice cream includes an evaporator system with a secondary evaporator. The evaporator system includes a cooling chamber having an ice cream input and an ice cream output. A valve can be placed at the ice cream input to achieve dry freeze operation. The valve can prevent the cooling chamber from being completely filled.
Abstract:
A method for processing food product includes detecting non-metallic equipment fragments or pieces in the food product during processing by employing processing equipment or components fabricated of a material which comprises a non-metallic primary constituent and a detectable particulate metal constituent interspersed substantially throughout the primary constituent such that no substantial adverse effect on the formability, during manufacture, or structural integrity, during use, of the piece part results, and such that a fragment or piece of the composite material is detectable by use of means for detecting the particulate metal constituent
Abstract:
An ice cream machine for cooling liquid ice cream into frozen ice cream includes an evaporator having an automatic expansion valve, a temperature control circuit, and an accumulator/heat exchanger. An auxiliary tank or section of the evaporator can ensure that a cooling chamber is surrounded by liquid refrigerant during normal operation. The flooding of the cylindrical cooling tank, the expansion valve, the temperature control circuit, and the accumulator/heat exchanger provide more efficient and even cooling in an interior cooling chamber. The more efficient cooling allows the ice cream machine to utilize a smaller compressor, thereby reducing the cost and energy consumption of the ice cream machine. The auxiliary tank can be a coil of tubing, a cylindrical container positioned above the cylindrical cooling tank, or a portion of the cylindrical cooling tank.
