- Description
- (i) This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; prices are being requested and a written solicitation will not be issued. (ii) This solicitation number RFQ-037-4384-04 is issued as a request for quotation. (iii) The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 01-24. (iv) This procurement is unrestricted. The NAICS code is 333294, Food Product Machinery Manufacturing. The small business size standard is 500 employees. (v) CLIN1 - Extruder, 1 each. CLIN 2 - Additional charge for extruder being designed for installing other external extrusion devices such as on line rheometer, slot dies, dies for the production of tubes or blow films, or die face pelletizing devices, 1 each; CLIN 3 - Additional charger for extruder being designed ready for/or capable of installing devices for running food products under supercritical carbon dioxide; CLIN 4 - Additional charge for extruder being designed for fast barrel assembly and reconfiguration; CLIN 5 - Additional charge for extruder having capability of operating at continuous die pressures of at least 2000 PSI. (vi) BACKGROUND - Twin screw extruders are considered cutting edge technology in the production of a variety of snack type and ready to eat foods from grains, vegetables and other food materials and ingredients. The requested Laboratory/Pilot Plant size extruder is to be utilized in studies by the USDA ARS Food Science Research Unit leading to add value to food ingredients derived from vegetables, especially sweetpotatoes. These studies will develop breakfast cereals, snack foods, functional ingredients and other extruded products from sweetpotatoes and other vegetables and their ingredients. The extruder will also be used in investigating the hydrolysis of starches/flours from new cultivars of industrial-type sweetpotatoes being developed by the breeding programs for starch derivatives, syrup and alcohol production. This will support the efforts on increased utilization of underutilized sweetpotatoes and other vegetables through development of new processing technologies. Specifications for a Twin-Screw Cooker Extruder: (1) The twin screw extruder shall have minimum screw diameter of 18mm and maximum of 32 mm. (2) Screw speed shall be operable over the range of 0 to 1,200 RPM and able to provide constant torque over the range of 1200 RPM down to 120 RPM. (3) Extruder shall have a drive AC motor of 10 to 30 HP. Constant torque/speed range 100:1. 460 V, 3 Phases electric power shall be supplied for installation. (4) Gearbox shall be equipped with anti-friction type thrust bearings, splash lubricated, and water-cooled. (5) Motor shall be directly coupled to the gearbox with preferable nominal screw speed up to 1200 RPM. (6) Screw shafts shall be splined and made from high-strength alloy steel and guaranteed to be non-corrosive. (7) Barrel Sections shall be up to 200 mm long and electrically heated. Each barrel section shall be equipped with thermocouples to determine both barrel and product temperature. Barrels shall be internally cored for water-cooling. Also, barrels shall be designed for adding sensors on each barrel and in the die assembly to measure pressure or melt. (8) The extruder shall have a minimum of six barrel sections and a minimum of a L:D ratio of 24:1 with options for additional barrel sections. Also, the extruder shall be pre-wired for future barrel extension. (9) The feeder-barrel section shall be able to be water-cooled. (10) Extruder shall contain removable barrel sections and they shall be able to be arranged in the sequence desired. Also, extruder shall contain a minimum of three barrel sections with ports for feed additions and/or venting of gases. Covers or contoured plugs shall be included. Discharge pressure shall be monitored and protected from pressure overload. (11) Extruder shall contain a minimum of five independent temperatures controllable, heating and cooling, zones. The heated zones shall be able to reach at least 300oC. (12) Extruder shall have an alarm system alert and both mechanical and electrical torque overload protector. The torque limiter shall be capable to disengage when screw shaft torque exceeds 110% of rated value. (13) The extruder shall contain a die plate holder with die pressure and die temperature outputs. Different types of dies including co-extrusion die should be available in various shapes including chips, sticks, bars and co-extruded products. (14) The extruder shall have co-rotating, intermeshing screw elements with fully self-wiping profiles. Right and left handed screw elements and two and three lobe kneading blocks shall be available. (15) The extruder shall have a loss-in-weight gravimetric or volumetric feeder and other necessary accessories such as pumps and face die cutter. The extruder shall accept feed stock in the form of powder, pellet, chip, melt, paste and solutions, through a hopper. (16) The extruder shall be able to produce representative products with output of 1 kilograms per hour, to above 50 kilograms per hour. (17) The extruder shall be constructed for use with food products and suitable for starchy food research. Information on the use of this extruder in food research shall be provided by means of references in extensive research publications from nationally and internationally recognized scientific journals. (18) The extruder shall have a control cabinet with available controls and appropriated indicators for power on-off, screw RPM, torque, die pressure, die temperature, barrel and product temperatures. Information collected shall be transferred to an automatic data collection system, Windows-based software and computer supplied by the contractor. (19) Products developed in the extruder shall be scalable to large production model extruders. (20) The contractor shall have existing pilot plant facilities in the U.S. where scale-up test can be run on larger commercial scale food grade extruders. (21) The contractor shall provide with the extruder, screw elements typically used in food R & D application. Length of supplied screw elements shall cover the whole length of the screw shafts. Additionally, the screw configuration shall be supplied according to user?s specifications for processing starchy materials, fruit and vegetable purees, snack foods, bars with filling, and high moisture extruded products. (22) The contractor shall deliver the extruder within 270 days after receipt of purchase order with complete technical specifications. A schedule for delivery that would be convenient for USDA-ARS will be arranged.
