Abstract: An apparatus for dispensing and agitating objects to be treated in a liquid is described in terms of the use of the apparatus in the processing of potato chips in cooking oil. The apparatus comprises an automated kettle rake (100) for use in the processing of potato chips or other objects (101) in a kettle (102) filled with cooking oil or other desired liquid (103), involving an agitation manifold (104) movably mounted above the kettle (102) and a dispersal manifold (106) positioned inside the kettle (102). The agitation manifold (104) disperses the chips or other objects by injecting fluid through at least one nozzle onto the liquid in the kettle (102) while passing over the length of the kettle (102). Optionally, the cooked chips or other objects may be swept onto a removal conveyor (110) after processing is completed.

Abstract: A faucet for dispensing flat malt beverage and a smooth, creamy and stable foam having a shiftable faucet shaft which in one position dispenses flat beer and in a second position provides an alternate flow path through restricted orifices which increase the velocity of the malt beverage so that it draws air into the faucet housing through orifices therein and incorporates the air into the foam to dispense a stable, creamy foam from the faucet discharge port.

Abstract: A beer foaming process and apparatus in which a smooth stable foam is formed by intimately admixing a nitrogen containing gas, preferably air, by a Venturi effect in a nozzle positioned on the beer tap. The nozzle has a mixing chamber with a perforated plate at its intake end to divide the flow of beer from the keg into smaller streams of higher velocity in the mixing chamber, intake ports in the side walls of the chamber for admitting gas into the chamber, and a screen of 30 to 200 mesh at the discharge end of the nozzle to form the stable foam discharged from the chamber.

Abstract: A new method for intensifying the inherent flavors of foods and for imparting other desirable organoleptic properties is disclosed. The method consists of adding to foodstuffs a flavor enhancing amount of a heat denatured concentrate of beer. There is also provided a process for producing the above described concentrate.

Abstract: In the brewing of beer, spent grain at about 90% moisture from a straining tank having no internal rotating rake is collected and pumped to a centrifuge which reduces the moisture of the spent grain to about 70% and provides spent grain liquor of about 2.0 to 4.5% or more of total solids. The spent grain liquor is stored in a tank at 165.degree. F. to 170.degree. F. and held until it is used up to 50% of the sparge liquid for a subsequent brew in the straining tank. The spent grains at about 70% moisture are directed to a large holding tank. Nutritious brewery waste streams are added thereby increasing the nutritional value.
