Standard Specification for Vegetable Peeling Machines, Electric
ABSTRACT
This specification covers batch-type electric vegetable peeling machines of the following style: Style 1, Size A, and Style 2, Size A, Size B, and Size C. The cylinder or hopper shall be sheet aluminum or stainless steel, or cast iron. Machines intended for marine applications shall be furnished with a stainless steel cylinder. The inside surface of all cylinders shall be covered by silicon carbide or aluminum oxide. The disk shall be cast aluminum, formed stainless steel, or reinforced plastic. The cylinder covering ring shall be cast aluminum, spun sheet aluminum, or fiberglass-reinforced plastic. The supporting base of the flour mounted Style 2 machine shall be steel, aluminum, or stainless steel. The vegetable peeler shall comply to the specified physical requirements specified for the following: (1) cylinder or hopper, (2) disk, (3) vegetable outlet, (4) peel trap, (5) waste outlet, (6) water inlet and sprayer, (7) cylinder covering ring, (8) Style 1, counter mounted, (9) Style 2, floor mounted, (10) waste disposer, (11) electrical devices such as motors, wiring, timer, and switch, and (12) piping, tubing, fittings, and valves. The peeler shall meet the hazard protection requirements including switch guard and shall conform to the performance requirements which shall be tested by operational test.
SCOPE
1.1 This specification covers batch-type vegetable peeling 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 The following safety hazards caveat pertains only to the test methods portion, Section 9, of this specification: 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.
