30、mbined machine machine combining two or more functions of pasteurizer, ageing vat, cream cooker, batch freezer 4 Performance characteristics 4.1 Loading of pasteurizer and cream cooker The machines shall operate at ambient temperature (see 5.3). The pasteurization tank of the machines shall be loade
31、d 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 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
32、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 shall 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
33、 declared by the manufacturer with the reference test mix at a temperature of 5 C 1 C . The machine shall work the time required for the reference test mix reaches the temperature 20 % discharged Quantity 80 % of the Total Load 4.3 Loading of combined machine The machine shall operate at ambient tem
34、perature (see 5.3). The machine shall be loaded with the 75 % of the maximum amount, expressed in kilogramme, indicated by the manufacturer of the reference 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 tem
35、perature expected (5.5.4). The machine shall work the time required for the reference test mix reaches the temperature 20 % discharged Quantity 80 % of the Total Load 4.4 Product temperature/Extrusion temperature The extrusion temperature of the reference frozen mix (Clause 6) depends on the adjusti
36、ng and setting of the freezing equipment and is directly related to the characteristics of the final product. The extrusion temperature of the reference frozen mix (Clause 6) affects the energy consumption of the batch freezer and combined machines. 4.5 Overrun Generally, during the freezing, the te
37、st 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 into 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 r
38、elated to the characteristics of the final product. The overrun of the product obtained with the reference mix (Clause 6) affects the energy consumption 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 ro
39、om 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 side wall, are designed to create an even, horizontal air flow within the test room. By convention, the distance separating these two technical side w
40、alls 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 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 thermal
41、ly 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) should be used for the building of a new test room. The floor shall be made of concrete or of thermally equivalent material and/or shall be sufficient
42、ly insulated to ensure that external climatic conditions do not affect the floor temperature. 5.1.2 Thermal characteristics An experimental evaluation of the test-room performances shall be carried out minimum once per year. Air temperature measured at different points shall not deviate from the rat
43、ed temperature of the test-room by more than 2 K. The test room shall be capable of maintaining values of humidity within 5 units of the relative humidity percentage figures of the rated humidity of the test room temperature class at the specified measuring points. BS EN 16754:2016EN 16754:2016 (E)
44、8 The surface temperatures of the walls shall remain within a tolerance of 2 K in relation to the air temperature measured in the test room.

Confirm (while the machine compressor(s) are energized) that the supply voltage is within 2,5 % of the operating voltage specified by the manufacturer. Record the test voltage for each test and indicate the value in the test report. 5.5 Test cycle 5.5.1 Pasteurizing Test Cycle The pasteurization cycles of the reference test mix is the following: start from “Stop”
