EN 16754:2016 (E) 4 1 Scope This European Standard specifies requirements and test conditions of machines for processing Artisan Gelato, ice cream and similar frozen desserts. It defines machines performance characteristics and energy consumption, measured under specified conditions and test methods, using a reference test mix. This European Standard applies to professional machines having a maximum capacity of 400 l, for thermal-treatment of Artisan Gelato, ice cream and similar frozen desserts listed as follows: — pasteurizers; — ageing vats; — cream cookers; — batch freezers; — combined machines. The machine can be factory assembled or field connected to a remote condensing unit. The machine can include separate remote refrigeration systems for the frozen product and fresh mix and can be either air-cooled or water-cooled. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 compression type machines machines where the cooling is performed by means of a refrigerant liquid at low pressure in a heat exchanger (evaporator), the steam thus formed becomes a liquid by a mechanical compression higher pressure and cooling in another heat exchanger (condenser) 3.2 condenser heat exchanger in which after compression, the vaporized refrigerant is liquefied, giving off heat to external cooling system 3.3 evaporator heat exchanger in which, after the reduction of pressure, the refrigerant is vaporized by absorbing heat from the medium which is cooled SIST EN 16754:2016



EN 16754:2016 (E) 5 3.4 condensing unit system assembled in factory to run part of the refrigeration cycle (compression and condensation), including one or more refrigerant compressors, condensers, liquid tanks, piping systems and ancillary equipment assembled on a common basis 3.5 pasteurization cycle cycle during which test mix is heated for a time fixed to different type of pasteurization and then immediately cooled to conservation temperature, to avoid the bacteria’s development 3.6 conservation temperature temperature below which the text mixture shall be kept 3.7 product temperature/extrusion temperature temperature of the frozen product immediately after extrusion 3.8 normal load load obtained when the machine is operating at ambient temperature at climate class declared by the manufacturer using the test mixture in the quantity and at the temperature specified by this standard 3.9 overrun percentage increase in volume due to the addition of air to frozen product whose calculation is the ratio between the liquid mix and the drawn frozen product 3.10 reference test mix mix specifically prepared for testing 3.11 frozen product product obtained after freezing test cycle of the reference test mix 3.12 climate class range of ambient temperature in which the machines are intended to be used 3.13 time of cycle time required by the machine to complete the foreseen cycle 3.14 artisan gelato self-made frozen dessert 3.15 pasteurizer machine used for mixing, heating, cooling ingredients in order to produce and store the mix for artisan gelato SIST EN 16754:2016
