This is a Questions and Answers document for RFQ 1232SA26Q0928, a Request for Quotation issued by the USDA Agricultural Research Service for a commercial food-grade juicer with a shattering helical gear destined for the Plant Science Research Center in St. Paul, Minnesota. The document clarifies technical specifications and manufacturer requirements for potential vendors responding to the solicitation.

The equipment must feature counterrotating tapered twin screws with 0.1 mm separation, a 0.3-0.4 mm filtration screen, and minimum processing capacity of 60 kilograms of carrots per hour with at least 85% extraction efficiency. Power requirements are 220V, 750W, single-phase minimum 1 horsepower, with all food contact surfaces constructed of SUS-304 stainless steel and no plastic components. The unit must weigh less than 150 kilograms, be capable of processing unmasticated undiluted alfalfa during eight-hour operational shifts, and be delivered via lift-gate to 1535 Lindig Street, St. Paul. The Q&A confirms that factory-documented off-the-shelf twin-screw designs are required with no functional substitutes such as single-screw or pulping alternatives permitted, and any deviations from specifications will not be assumed as compliant. Vendors should note that any manufacturer, brand, model, or part number is acceptable provided all stated specifications are met. This is an unrestricted acquisition with a North American Industry Classification Standard Code of 333241 and a small business size standard of 500 employees.
