(Test Method)Standard Test Method for Performance of Conveyor Toasters
Standard Test Method for Performance of Conveyor Toasters
SIGNIFICANCE AND USE
The energy input rate test is used to confirm that the conveyor toaster is operating properly prior to further testing.
Preheat energy and time can be useful to food service operators to manage power demands and to know how quickly the conveyor toaster can be ready for operation.
Idle energy rate and pilot energy rate can be used to estimate energy consumption during non-cooking periods. In addition, a power saving mode (if applicable) will demonstrate energy savings during idle periods.
Production capacity information can help an end user to better understand the production capabilities of a conveyor toaster as it is used to cook a typical food product and this could help in specifying the proper size and quantity of equipment. If production information is desired using a food product other than the specified test food, the test method could be adapted and applied.
SCOPE
1.1 This test method evaluates the energy consumption and cooking performance of conveyor toasters. The food service operator can use this evaluation to select a conveyor toaster and understand its energy consumption.
1.2 This test method is applicable to gas and electric conveyor toasters.
1.3 The conveyor toaster can be evaluated with respect to the following (where applicable):
1.3.1 Energy input rate and preheat temperature profile (10.2),
1.3.2 Preheat energy consumption and time (10.3),
1.3.3 Idle energy rate (10.4),
1.3.4 Pilot energy rate (if applicable, 10.5),
1.3.5 Cooking energy rate (10.8), and
1.3.6 Production capacity (10.8).
1.4 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only.
1.5 This test method may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
