A multi-stage floatation dispenser for carrying a ballast, which may be a non-water consumable dispersant and at least one water consumable dispersant wherein the weight of the water consumable dispersant decreases as the water consumable dispersant is consumed with the weight of water consumable dispersant and the non-water consumable coordinated with the flotation capacity of a flotation dispenser to provide for either a two stage or a three stage dispensing mode.

A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition, the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

A system for dissolving solid chemical may include three reservoirs positioned in a vertically stacked arrangement. A solid chemical reservoir configured to receive solid chemical to be dissolved may be nested in a solution generator reservoir into which water is introduced to erode the solid chemical. A dissolved chemical reservoir can be positioned under the solid chemical reservoir and the solution generator reservoir. The dissolved chemical reservoir can store solution generated using the system. In some examples, a recirculation circuit is used to recirculate water introduced into the solution generator reservoir until a solution having a target concentration of the chemical being dissolved is achieved. The recirculation circuit may include a recirculation line having an outlet aimed at the bottom wall of the solid chemical reservoir.

To provide method and apparatus for producing alkaline water, capable of preventing mixture of fine particles derived from a gas dissolving membrane device into hydrogen water. An apparatus for producing alkaline water for cleaning electronic device includes: a pH adjusting device 11 configured to adjust ultrapure water to be alkaline; a deaeration device 13 configured to deaerate the ultrapure water adjusted to be alkaline; and a gas dissolving membrane device 14 having a gas permeable membrane to dissolve functional gas into the deaerated ultrapure water.

A beverage dispenser (1) includes a cold water tank (20) for storing cold water (50), a carbonation tank (30) disposed with at least a bottom portion thereof being submerged in the cold water (50) in the cold water thank (20), the carbonation tank being configured to generate carbonated water (60) by adding carbon dioxide gas to the cold water (50) supplied from the cold water tank (20), a carbonated water outlet passage (35) for taking out the carbonated water (60) from the carbonation tank (30) and a heater (41) for heating the cold water (50) in the cold water tank (20). In order to sterilize the above beverage dispenser (1), the heater (41) is caused to heat the cold water (50) in the cold water tank (20) to a temperature higher than a predetermined temperature, thereby to sterilize the cold water tank (20) and the carbonation tank (30). After the carbonated water (60) in the carbonation tank (30) is taken out via the carbonated water outlet passage (35), hot/warm water (70) in the cold water tank (20) is cooled.

The invention relates generally to a mixing system for mixing a dry material with a liquid. The mixing system includes a supply of dry material and a supply of liquid. An infinitely variable metering device meters the dry material into the liquid. A sensor senses the ratio of dry material to liquid. The sensor is operatively connected to the metering device to control the metering device to obtain a desired ratio of dry material to liquid. The dry material is dispensed volumetrically by volume of liquid to form the desired ratio of dry material to liquid.

A grease and food particle trap for use with an oven shooter tube cleaning system that provides improved resistance to clogging and improved maintenance better matching the ability of the shooter tube cleaning system to provide complete cleaning and removal of grease and food particles is provided. An auxiliary heating system may provide improved energy efficiency and temperature control for cleaning operation by separately heating the cleaning solution upstream from the shooter tube prior to delivering a cleaning spray to the cooking volume.

The present invention discloses a methanol-mediated method for separating an alkaline solution of hemicellulose, and an ethanol-mediated method for separating an alkaline solution of hemicellulose, where methanol/ethanol is added into the alkaline solution in which hemicellulose is dissolved, and stirred thoroughly until the mixture is homogeneous, to destroy the hydrated layer effect formed between the hemicellulose and the alkaline solution through the methanol/ethanol-mediated hydrophobic effect, such that hemicellulose is precipitated from the solution system, and then the mixture is subjected to separation by sedimentation, centrifugation or filtration to obtain a precipitate of hemicellulose and an alkaline solution of methanol/ethanol; and by using the prompting effect of an alkaline condition on evaporation and gasification separation of methanol/ethanol from water, a reduced-pressure distillation (rectification) or gasification membrane is used to separate methanol/ethanol from the alkaline solution, and the obtained alkaline solution and methanol/ethanol are reused for dissolution and separation of hemicellulose. By the complete reuse of the alkaline solution and methanol/ethanol in the method of the present invention, it achieves efficient, clean and economical production of alkaline dissolution and separation of hemicellulose, and the separation and recovery efficiency of the hemicellulose dissolved in the alkaline exceeds 99%.

A method and apparatus for obtaining a product chemistry from a solid block is provided. The product is housed within a dispenser, which utilizes a liquid and a gas to erode the block and produce a concentrate solution. The liquid and gas characteristics can be adjusted in the field to achieve a predetermined concentrate level in the solution. The introduction of air into the dispenser saves water, while producing higher concentrate levels.

A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.
