Abstract:
We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid. The detergent can be used in a variety of high temperature and low temperature automatic warewashing machines including large multizone conveyor machines, or relatively small institutional machines that have a single washing chamber.
Abstract:
A flexible container and method for dispensing ready-to-use pesticide compositions utilize a flexible package filled with a thick, semi-solid flowable ready-to-use pesticide composition which may be manually gripped, oriented proximate a pesticide application area, and squeezed to controllably dispense the ready-to-use pesticide composition through an opening or dispensing port in the flexible package. Dispensing of the pesticide composition may be performed by a single hand with controlled and discrete product placement, thereby permitting pesticide composition to be applied in difficult to reach areas such as dark and cramped cracks and crevices.
Abstract:
The invention is a method of sanitizing and destaining ware, including silverware. In its most preferred mode the method comprises the steps of applying a sanitizing concentrate composition to silverware at a rate of 100 ppm to 2000 ppm, the sanitizing concentrate composition including from about 1 wt. % to 20 wt. % of peroxycarboxylic acid, from about 10 wt. % to 50 wt. % of carboxylic acid comprising a mixtures of acetic acid, and octanoic acid, said acetic acid and said octanoic acid present in a ratio ranging from about 10 to 1 to about 1 to 1, respecitvely, from about 3 wt. % to 35 wt. % of hydrogen peroxide, and a balance of carrier wherein said peroxycarboxylic acid comprises the reaction product of said acetic acid, octanoic acid, and hydrogen peroxide.
Abstract:
The invention includes compositions and methods for sanitizing ware without staining or spotting. In its most preferred mode, the method comprises the steps of washing the ware in an automated ware washing machine and rinsing the ware at either high or low temperatures with a sanitizing rinse composition. The destaining, sanitizing concentrate composition preferably comprises peroxyacetic acid, acetic acid, and hydrogen peroxide. The sanitizing rinse composition may preferably be used at a concentration ranging from about 600 ppm to 4,000 ppm.
Abstract:
The invention provides a urea based solid composition and a process for preparing a homogeneous, urea-based, solid cleaning composition. Cleaning compositions for use in warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, and the like, made by the method are also provided. The ingredients are charged into a heated mixing apparatus and when uniform are transferred into a mold or other packaging system for dispensing the detergent. The consistency of the composition ranges from that of a fused solid block to a malleable article.
Abstract:
A low product level detector is disclosed which utilizes a sensor comprised of an infrared emitter (103) and receiver (104) to project a beam of light (105) across a cavity/enclosure which contains a solid product (65). When the product reaches a level at which more solid product should be added, an alarm indicia means is triggered. The alarm indicia means is comprised of an audible horn (106) and a visually perceptible light (107). The low product alarm is utilized in a dispenser (10) for dispensing a wash chemical solution which has been created by dissolving a solid wash chemical in a diluent. By maintaining a predetermined amount of solid wash chemical in the dispenser, the wash chemical solution maintains a more constant concentration.
Abstract:
Ethylene oxide/propylene oxide block copolymers having high cloud points, when compared to conventional rinse agent materials, have surprisingly been found to be useful in the manufacture of effective low foaming rinse aids. The rinse aids are prepared by combining the high cloud point copolymer with an effective defoamer and a water miscible diluent. The rinse aid composition can achieve adequate rinsing at common aqueous rinse temperatures at a concentration of the block copolymer in water less than 500 parts of the block copolymer per million parts of water. A liquid rinse agent concentrate can take the form of a low viscosity liquid, a thickened pourable or semi-pourable aqeous liquids. A solid rinse agent concentrate can be a cast solid material packaged within a soluble or disposable wrapper or capsule or other water soluble package. The rinse aids can be dispersed in a variety of ways by dilution with water to an aqueous final rinse composition. The uniqueness of the invention relates to the fact that all components are not expected to be active as sheeting agents and are approved as food additives thereby eliminating any health concerns associated with residual deposits of the composition on cleaned ware.
Abstract:
A thermoplastic compatible lubricant concentrate containing alkylpolyglycoside suitable for use in lubricating conveyor belts in the transporting of thermoplastic article of manufacture. The hydrophobic group of the alkylpolyglycoside is a long chain alkyl group having 5 to 30 carbon atoms. The degree of polymerization of the saccharide units in the polyglycoside is less than 3.
Abstract:
An apparatus and method for dispensing solid rinse aids is disclosed. The dissolved solid rinse aid is dispensed from a dispenser (100) to a solution tank or reservoir (40) which uses the heat of a high temperature warewash machine (10) to prevent bacterial or microbial growth and degradation of rinse aid solutions held within the reservoir (40). The dispenser (100) is a solid rinse aid dissolving unit that is preferably a gravity feed device dispensing solutions to the solution tank (40) located within the warewash machine (10). The dispenser (100) is fed with hot tap water or final rinse water to dissolve the solid rinse aid.
Abstract:
A system for diluting and dispensing concentrated liquid products is disclosed. The system includes a dispensing device (10, 150) containing a removable variable proportioning means such as an aspirator assembly (40, 154). A concentrate pickup tube (114) attaches to the dispensing device and is in fluid communication with the aspirator assembly. The dispensing device can utilize a rigid outlet tube (20, 159) which is removably attached to nozzle tip (18, 158) for dispensing to large containers. Also disclosed is a method for diluting and dispensing chemical solutions using the dispensing device of the invention.
