1、Designation:F214409An American National StandardStandard Test Method forPerformance of Large Open Vat Fryers1This standard is issued under the fixed designation F2144;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last r
2、evision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the energy consumption andcooking performance of large-vat open,deep fat fryers.Thefood service operator
3、can use this evaluation to select a fryerand understand its energy efficiency and production capacity.1.2 This test method is applicable to floor model gas andelectric fryers with 50 lb(23 kg)and greater fat capacity andan 18-in.and larger vat size.1.3 The fryer can be evaluated with respect to the
4、following(where applicable):1.3.1 Energy input rate(10.2),1.3.2 Preheat energy and time(10.4),1.3.3 Idle energy rate(10.5),1.3.4 Pilot energy rate(10.6,if applicable),1.3.5 French fry cooking energy rate and efficiency(10.9),1.3.6 French fry production capacity and frying mediumtemperature recovery
5、time(10.9),1.4 This test method is not intended to answer all perfor-mance criteria in the evaluation and selection of a fryer,such asthe significance of a high energy input design on maintenanceof temperature within the cooking zone of the fryer.1.5 The values stated in inch-pound units are to be r
