39、Test Methods11.1 This test method measures the ability of a freezer tocontinuously produce frozen product at a given rate. If aproduction rate is not stated by the manufacturer, the freezershould meet the minimum rate of the appropriate ASTM size(see 4.3).11.2 Test Preparation:11.2.1 Ambient air tem
40、perature should be 75 to 80F (24 to27C) for air-cooled freezers. Inlet cooling water shall be 80F(27C) minimum for water-cooled freezers.11.2.2 Test mix formulations shall contain 32 to 37 % solidsfor softserve and 24 to 28 % solids for shake. Mix temperatureshould be 40 to 42F (4 to 6C) when put in
41、to the freezer.11.2.3 Finished product parameters for the capacity testshall be within this range:Softserve 18 to 20F (8 to 7C) 50 % max overrunShake, without syrup 26 to 29F (3 to 2C) 60 % max overrun11.2.4 The freezer shall be set up in accordance with themanufacturers instructions. Start the init
42、ial freeze down andallow the unit to cycle off. Draw approximately one pint ofproduct to start a refrigeration cycle. Begin the capacity testwhen the freezer cycles off.11.2.5 Draw product into an 8-oz (237-mL) container forSize 1 and 5 freezers. For all other freezers use a 16-oz(473-mL) container.
43、 Determine the draw rate by dividing 225by the manufacturers rating (finished volume gallons per hour(litres per hour) when drawing an 8-oz sample. Divide 450 bythe manufacturers rating (finished volume gallons per hour(litres per hour) when drawing a 16-oz sample. See Table 1 fortypical rating samp
44、les.11.2.6 Record finished product temperature and overrunpercentage in accordance with Table 2.11.2.7 The capacity test shall be conducted for one hour.Additional mix at 40 to 42F (4 to 6C) may be added to themix reservoir during the test.11.3 Precision and Bias:11.3.1 No statement is made about ei
45、ther the precision orbias of the test method in 11.2.5for measuring the gallons perhour (litres per hour) capacity since the result merely stateswhether there is conformance to the criteria for successspecified in the procedure.12. Inspection12.1 Inspection of the material shall be agreed upon be-tw
46、een the purchaser and the supplier as part of the purchasecontract.13. Rejection and Rehearing13.1 Material that fails to conform to the requirements ofthis specification may be rejected. Rejection should be reportedto the producer or supplier promptly and in writing. In case ofdissatisfaction with
47、the results of the test, the producer orsupplier may make claim for a rehearing.TABLE 1 Typical Rating ExamplesGallons per Hour Litres per Hour Sample Size, oz Seconds per Sample1 3.8 8 225519 4510 38 16 4515 57 16 3020 76 16 22.530 114 16 1540 151 16 11.25100 379 16 4.5F160402314.
