Standard Specification for Bun Slicing Machines

ABSTRACT
This specification covers commercial, electrically operated, bun slicing machines. These slicing machines are classified by type, class, size and style. These machines have three types: Type I is electrically operated with single knife, Type II is electrically operated with dual knife, and Type III is a cluster-bun slicing machine, electrically operated with dual knife. They are also designated into three classes: Class I with a fixed chute, Class II with a adjustable chute, and Class III with automatic/conveyor feed. In terms of size, they come in three kinds: Size I (small), Size II (medium), and Size III(large). In terms of style, they can be classified into three kinds: Style I which is counter top or bench-mounted, Style II which is floor-mounted, and Style III which is portable. Bun slicing machines shall be delivered assembled, ready for mounting, connection to electricity, and use as applicable. The bun slicing machine shall be simple to disassemble and reassemble without special tools or equipment. Requirements for power supply, motor, motor controller, and cutting knife shall be discussed. All components and assemblies of the dough divider and rounder shall be free from dirt and other extraneous materials, burrs, slivers, tool and grind marks, dents, and cracks. Castings, molded parts and stampings shall be free of voids, sand pits, blow holes, and sprues. External surfaces shall be free from kinks, dents, and other deformities. Forming and welding shall not cause damage to the metal and shall be done neatly and accurately.
SCOPE
1.1 This specification covers commercial, electrically operated, bun slicing machines.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
