20、: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
21、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
22、 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 o
23、f 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
24、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
25、 heat from the medium which is cooled DIN EN 16754:2016-05 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 e

32、g of pasteurizer and cream cooker The machines shall operate at ambient temperature (see 5.3). The pasteurization tank of the machines shall be loaded with the maximum amount, expressed in kilogramme, indicated by the manufacturer with the reference test mix (see Clause 6) at 20 C 1 C. The machines
33、shall be operated as long as necessary so that the reference test mix reaches the heating temperature expected (5.5.1) and shall then proceed to the cooling cycle to the storage temperature 5 C. 4.2 Loading of batch freezer The machine shall operate at ambient temperature (see 5.3). The machine shal
34、l be loaded with the 75 % of the maximum amount, expressed in kilogramme, indicated by the manufacturer or with the average of the values min and max declared by the manufacturer with the reference test mix at a temperature of 5 C 1 C .

The machine shall be loaded with the 75 % of the maximum amount, expressed in kilogramme, indicated by the manufacturer of the refe
36、rence test mix (see Clause 6) at 20 C 1 C. The machines shall be operated as long as necessary so that the reference test mix reaches the heating temperature expected (5.5.4). The machine shall work the time required for the reference test mix reaches the temperature 20 % discharged Quantity 80 % of
37、 the Total Load 4.4 Product temperature/Extrusion temperature The extrusion temperature of the reference frozen mix (Clause 6) depends on the adjusting and setting of the freezing equipment and is directly related to the characteristics of the final product. The extrusion temperature of the referenc
38、e frozen mix (Clause 6) affects the energy consumption of the batch freezer and combined machines. 4.5 Overrun Generally, during the freezing, the test product (Clause 6) and air enter in the freezing chamber, where a beater assemblies scrapes ice crystals from the chamber walls and blends the air i
39、nto the test mix. The overrun of the reference frozen mix (Clause 6) depends on the adjusting and setting of the freezing equipment and is directly related to the characteristics of the final product. The overrun of the product obtained with the reference mix (Clause 6) affects the energy consumptio
40、n of the batch freezer and combined machines. 5 Energy consumption test 5.1 Test room 5.1.1 General design, walls, floor and radiant heat The test room shall be a parallelepiped space in which two of the opposite side walls, referred to as the discharge technical side wall and the return technical s

By convention, the distance separating these two technical side walls is referred to as the “length” of the test room. The minimum useful dimensions (length, width, height) of the test room shall be dependent on the
42、overall dimensions (length, depth, height) of the machine to be tested. The ceiling and the two non-technical side walls of the room shall be thermally insulated and shall be equipped with an inner metal skin. A minimum insulation level equivalent to 60 mm of rigid polyurethane foam = 0,03 W/(m K) s
43、hould be used for the building of a new test room.
