Abstract: An automatic drying apparatus for drying vegetables and the like includes a support having at least three upstanding posts with lateral spaces between the posts for providing clearance for a conveyor extending from the dryer in at least one of three directions. The housing is suspended by a pendulum-type suspension from the support, the housing having an annular bottom wall, a side wall and a top wall with an opening therein. An open top basket is rotatably mounted in the housing, the basket having a cylindrical side wall and a conical bottom wall which is moveable along a vertical axis between a closed position wherein it engages the basket side wall and an open position wherein it is spaced appreciably below the basket side wall so that the contents of the basket can drop out of the basket onto a conveyor. The moving means for moving of basket bottom wall between its two positions are suspended below the basket bottom wall to minimize the height of the apparatus.

Abstract: An inexpensive portable ultra-filtration system for concentrating industrial waste fluids such as cutting coolant. The system is adapted for convenient use with standard storage containers. It is lightweight, portable, and reliable, and processes waste fluids in conformance with most local environmental regulations. Its low cost makes it ideal for small volume applications. The system operates by continuously recycling the waste fluid through a cartridge prefilter and then a carriage ultra-filter. It can process a fifty-five gallon drum of contaminated coolant to yield fifty gallons of clear permeate and only five gallons of concentrated contaminated mixture in about twenty-four hours. The clear permeate can be directly sewered in most locales. An inlet pipe may be used to keep the point of waste fluid intake above most of the heavy contaminants such as sludge, thereby lengthening the operating life of the filters.
