Description

The USDA-ARS in Wapato, WA has a requirement for a Hot Water Spraying System as follows: The multi-disciplinary project will require procuring an in-line apple/pear washing system which uses a spray of water using high pressure spray nozzles (24) under 6 headers delivering at 70-130 psi each. The system will recycle water at a rate of 10-70 gpm. The temperature of the water sprayed on the fruit will be regulated between 20 and a maximum of 70 degrees C. A contact loop for decay organism control will consist of a 30 sec to 1 min exposure at a maximum 70 degree C. The plumbing will consist of corrosion free chlorinated polyvinyl chloride (CPVC) pipes. Rollers will consist of removable and interchangeable brushes to accommodate a wide variety of fruit types. A stainless steel catach pan will recover water sprayed on the fruit and transfer it to a screen box. The stainless steel screen box will automatically remove larage particles (stems, leaves, etc.) which would otherwise plug the equipment. The system will contain a 15 HP close-coupled high pressure pump with an ODP motor to recirculate the water from the bottom of the screen box through the high pressure manifold. The heating system will consist of a 250,000 BTU/Hr propane heater, 80 gallon heat mix tank, small circulation pump, and controls. The system will contain emergency water by-pass to divert water away from the spray manifold. The system will contain a spray manifold for application of detergent and fresh water rinse. Half of the existing dipping tank on the test pilot packing line will be modified to accommodate the spray manifold and rollers (or interchangeable brushes). The system will be attached to the test pilot packing line. The system will be no longer than 10 ft. 1.75 inches in length, 2 ft. in width, and 4 ft. in height at the roller/brush aspect. The system must allow for containment of the washing fluids and for emptying of the system following use. This system must meet OSHA and Oregon engineering and electrical codes. A solicitation is not available for this notice. Interested firms are encouraged to submit proposals containing descriptive literature of the products to the mailing address shown in this notice. "This Procurement is Set Aside for Small Business Concerns". See numbered Note 22.*****
