Spray washing

In one extractor (FMC Inc.), the fmit is located between two cups having sharp-edged metal tubes at their base. The upper cup descends and the many fingers on each cup mesh to express the juice as the tubes cut holes in the top and bottom of the fmit. On further compression, the rag, seeds, and juice sacs are compressed into the bottom tube between the two plugs of peel. A piston moves up inside the bottom tube forcing the juice through perforations in the tube wall. A simultaneous water spray washes the peel oil expressed during extraction away from the peel as an oil—water emulsion the peel oil is recovered separately from the emulsion. 

Microstrainers. Microstrainers are rotating steel screens with extremely fine stainless steel mesh (85—170 perforations per square centimeter (13—26/in. )). The flowing Hquid enters the open end of the dmm and passes through the mesh to the effluent end. The mesh traps soHd impurities and rotates with the dmm. A wash-water spray washes the trapped soHds into a hopper for final disposal. The mesh is washed with filtered effluent discharged from jets fitted into the dmm and then exposed to uv radiation to inhibit microbial growth. The mesh is washed with chlorine water at intervals of 7 to 28 days in order to control slime growth removal efficiencies are 30—55% of the appHed BOD and 40—60% of suspended soHds. 

Steel, unless adequately protected with a film of oil subsequent to rolling mill operations, has a tendency to form surface rust rather quickly. This rust on the surface of the metal prevents proper conversion coating. A traditional method of removing rust is an acid applied by power spray equipment. The spraying action cleans both by physical impingement and the etching action of the acid. The power spray action is followed by a brush scrub, which further removes soil loosened by the acid. The brush scrub is followed by a strong alkaline spray wash, which removes all traces of the acid and neutralizes the surface.1-5...

Ultrasonic systems using less harmful and corrosive materials have been successfully used as an alternative to vapor cleaning. For example, stainless steel, which used to be cleaned with distillate-spray wash and vapor rinse using 1,1,1 -trichlo-roethane, has been replaced by immersion in ultrasonic bath containing trichloro-trifluoroethane and methanol. Hence the beneficial substitution of one organic solvent by a more environmentally friendly cleaner is possible.

In Table 3.1 some factors are stipulated that should be considered in the decontamination of meat (European Union, 1996). Spraying with 1.5-2.5% organic acids such as acetic or lactic acid is effectively applied on red meat carcasses (Canadian Food Inspection Agency, 2004). Lactic and acetic acid solutions are commonly used by the red meat slaughtering industry as an antimicrobial spray wash on freshly slaughtered beef carcasses. These spray washes are used in the early steps of beef carcass processing, usually applied to carcasses after hide removal, before and after evisceration, but before chilling (Berry and Cutter, 2000). 

Safety concerns have intensified with regard to the potential implications of pathogen behavior and the microbial ecology of carcass decontamination with organic acid spray washes of meat. On beef decontaminated with lactic acid increases of nearly 3 logs within five days of storage at 10°C under air or vacuum have been recorded, whereas increases were only 1 log and virtually nonexistent on untreated beef. Meat-packing...

A buildup of sodium salts took place at the top of the scrubber, near the wet/dry interface where the flue gas enters the scrubber. It is at this location that the process liquor first contacted the flue gas. A substantial evaporation of water from the scrubbing liquor took place leaving the sodium salts behind. These sodium salts are rather soluble in water and can, therefore, be easily cleaned by a periodic spray wash.
