About this file
This document is a specification sheet for a commercial food-grade juicer required by the USDA Plant Science Research Unit (PSRU) greenhouse in St. Paul, Minnesota.
The juicer must be manufactured entirely from food-grade stainless steel (SUS-304) with a 220V, 750W, 1-horsepower minimum motor operating at 1,450-1,750 rpm. Key performance requirements include processing 60 kilograms of carrots per hour with an 85% or greater grinding/extraction rate, utilizing dual counter-rotating tapered screws with 0.1mm tight tolerances, and employing a 0.3-0.4mm screen for liquid filtering. The device must accommodate continuous 8-hour shifts without cool-down periods, handle non-masticated, undiluted fibrous material such as alfalfa herbage, and weigh less than 150 kilograms. Critical design features include all moving parts enclosed with safety covers, no plastic components in the sample pathway, slow high-torque rotation to minimize heat buildup, easy disassembly without special tools, separate juice and pulp collection guides, automatic motor overload shutdown with switchable manual reverse mode, and an integrated stand with casters. The juicer must be an off-the-shelf, standardized item with readily available replacement parts rather than custom-built or one-of-a-kind equipment. Delivery to the USDA-PSRU-greenhouse at 1535 Lindig Street, St. Paul, Minnesota 55108 requires a city delivery truck equipped with a lift gate due to the absence of a loading dock at the facility.
