Standard Specification for Dough Divider and Rounding Machines

ABSTRACT
This specification covers commercial hand operated dough divider machines and semiautomatic and automatic, electrically operated, dough divider and rounding machines with or without interchangeable heads. Dough dividers and dough divider/rounding machines are classified by type, class, size, and styles: Types I, II, III, and IV; Classes I, II, and III; Sizes 1, 2, and 3; and Styles 1, 2, and 3. Operational test and performance test shall be performed to conform with the specified requirements.
SCOPE
1.1 This specification covers commercial hand operated dough divider machines and semiautomatic and automatic, electrically operated, dough divider and rounding machines with or without interchangeable heads.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

through S9),
5.1.7 When specified, the purchaser shall be furnished certification that samples representing each lot have been either tested
or inspected as directed in this specification and the requirements have been met. When specified, a copy of the test results shall
be furnished.

thereof.
6. Material
6.1 General—Dough divider, and dough dividing and rounding machines shall conform to NSF/ANSI No. 8 or BISSC Basic
Criteria and Standard No. 8. Materials used shall be free from defects that would affect the performance or maintainability of
individual components or of the overall assembly. Materials not specified herein shall be of the same quality used for the intended
purpose in commercial practice. Unless otherwise specified herein, all equipment, material, and articles incorporated in the work
covered by this specification are to be fabricated using materials produced from recovered materials to the maximum extent
possible without jeopardizing the intended use. None of the above shall be interpreted to mean that the use of used or rebuilt
products are allowed under this specification unless otherwise specified.
6.1.1 Stainless Steel: Stainless steel shall conform to the 300 series of Specification A167 or A240/A240M as applicable.
7. Design and Construction
7.1 General—Dough divider and rounding machines shall be delivered assembled, ready for mounting, connection to electricity,
and use as applicable.
7.2 Dough Divider—The Type I machine shall consist of a base, an operating handle, a manually operated dough dividing
mechanism (cutting head with stainless steel knives or other material meeting NSF/ANSI No. 51 or BISSC Basic Criteria and
Standard No. 8 requirements, and pressure board meeting the same material requirements), a yoke or support, and a removable
dough pan. The base of the Type I machine shall be provided with bolt holes for mounting. The overall dimensions of the machine,
1 1
excluding operating handle, shall fit into a 17 in. (423 mm) by 18- ⁄2 in. (470 mm) square area, 22- ⁄2 in. (565 mm) in height, 63
in. (76.2 mm) for each dimension.
7.2.1 Pan—The Type I machine shall be provided with a circular dough pan of one piece, deep drawn stainless steel or other
material meeting NSF/ANSI 51 or BISSC Basic Criteria and Standard No. 8 requirements. The pan shall be readily-removable and
shall have not less than one handle.
7.3 Dough Divider and Rounder—The Type II machine shall be semiautomatic consisting of a floor mounted support or stand
with integral housing, a manually operated dough divider mechanism (cutting head with stainless steel knives or other material
meeting NSF/ANSI No. 51 or BISSC Basic Criteria and Standard No. 8 requirements, and pressure board meeting the same
material requirements), an electric motor operated rounding mechanism (rounder plate), a yoke or support, and a removable work
pallet. The Type II machine shall divide the dough by manual operation and shall round the dough by an automatic operation. The
handle shall be fully depressed manually to engage the rounding mechanism for the rounding operation. The return of the handle
shall disengage the rounding mechanism. The Type III machine shall be similar in operation to the Type II machine with the
exception that the Type III machine is completely automatic, dividing and rounding dough automatically. The base of the Type II
and III machines shall be provided with bolt holes for floor mounting. The overall dimensions of the Type II and III machines
excluding operating handle, shall fit into a 27 in. (686 mm) by 27 in. (686 mm) square area, 59 in. (1499 mm) in height, 62 in.
(51 mm) for each dimension.
7.3.1 Rounder Plate and Work Pallets—Type II and III machines shall have a rounder plate and four work pallets constructed
of stainless steel or other material meeting NSF/ANSI No. 51 or BISSC Basic Criteria and Standard No. 8 requirements. The
rounder plate shall be attached to and driven by an electric motor as specified herein. The pallets shall have recesses of a number
corresponding to divider head assembly divisions, embossed on each work pallet for forming the rolls during rounding operation.
The pallet design and recesses shall meet NSF/ANSI construction requirements or BISSC Standard No. 8 requirements, or both.
Each pallet shall have one handle and shall rest in a fixed position on the rounder plate during operation. Work pallets shall be
removable.
7.4 Electrical Requirements:
7.4.1 Nominal Input Power—Unless otherwise specified (see 5.1.4), the machine shall be designed to operate on one of the
following:
7.4.1.1 120 V, 60 Hz, single phase,
