An apparatus for converting a dry material into a liquid concentrate includes a mixing vessel having an outlet opening, a dispenser for dispensing a predetermined weight of a dry material at a predetermined drop rate onto a predetermined drop location within the vessel, an inlet pipe connectable to a source of liquid for introducing a liquid into the vessel; a sensor for sensing the volume of liquid within the vessel; a pump for supplying a pressurized flow of recirculating liquid to the vessel; and a first, a second and a third agitating nozzle mounted within the vessel. Each agitating nozzle is operative to produce a jet of liquid oriented in a predetermined direction within the vessel. The nozzles are cooperable to generate within the vessel a moving body of liquid into which a dry material dispensed into the vessel is able to dissolve or to disperse.

Compounding apparatus and methods are provided for accurately compounding multiple source solutions in an efficient and automated manner. Liquids are transferred from their respective source solution containers to a common mixing chamber by pumps which are disposed between the source solution containers and the mixing chamber and fluidly connected to respective source solutions, and a controller which controls the pumps to operate in either fluid pumping mode or air pumping mode based at least in part on signals received from weight indicating devices associated with the tubing which extends between the pumps and the mixing chamber and/or weight indicating devices associated with the mixing chamber.

A method and an apparatus (1) serve for the automatic batch-wise production of a slurry containing a sugar component, i.e. sugar or a sugar substitute, for producing confectioneries. A liquid is fed into a weighing and mixing container (2) in a batch-wise and weight-accurate way. A sugar component as a dry material is fed into the container (2) in a batch-wise and weight-accurate way to produce a mixture. The liquid and the dry material are fed into container (2) and the mixture is mixed such that a slurry having a share of dry substance of at least 85% is produced. The liquid, the dry material, the mixture and/or the slurry is/are heated such that the slurry has a temperature of at least 70° C.

A method for blending dry material in a plant comprises automatically controlling fluidization of the dry material, transfer of the material, or both. In various embodiments, the automatically controlling comprises optimizing an amount of time that the dry material is fluidized prior to transfer, optimizing the transfer rate of the dry material, detecting and eliminating a developing plug of the dry material, estimating the weight of the dry material in the transfer line, minimizing dribbling during transfer of the dry material, and combinations thereof.

An automatic hybrid volumetric method of dispensing (HVD) improves on gravimetric dispensing and volumetric dispensing. The method dispenses ingredients for a mixture, according to pre-selected formulations, utilizing a supply of the fluid ingredients, an ingredient container, a power-driven plunger in the ingredient container, a mixture container, and a calibration weight scale. The plunger is movable to expel fluid in the ingredient container. The method includes several steps. The ingredient container is connected to the supply to receive a first ingredient in the ingredient container. The ingredient container is connected to the mixture container for the mixture container to receive ingredient expelled from the ingredient container by movement of the plunger. The method is calibrated by powering the plunger to move in the ingredient container a controlled distance, to expel ingredient to the mixture container, while weighing the increase in the weight of the mixture container, resulting in a calculated rate of weight dispensed per increment of movement of the plunger. The ingredients are dispensed according to the formulations in the weight amounts required by the formulations from the supply through the ingredient container to the mixture container, through calibrated movements of the plunger in the ingredient container.

An automated paint-batching system for producing paint cans of any size and color. The system includes a plurality of paint-batching cells, with each cell having a machine comprised of either one or two dispensing stations. When two dispensing stations are used, the two dispensing stations are: A first tint-station, where a small volumetric dispensing of the base, water-base or oil-base, of the paint is dispensed, in order to wet the bottom of the can, at which first station, thereafter, is dispensed all of the liquid colorants making up the formula of the paint can, at which the remainder of the base of the formula of the paint is dispensed, and a second base-dispensing station. Each of the first and second stations of the paint-batching machine of the invention has operatively associated therewith a weighing platform upon which rests the paint can during the dispensing at the respective station used in quality-control weighing of each dispensing. When only one dispensing station is used, all of the above-steps are performed at the one station. Each paint can has attached to it a bar-code label which represents a relocatable memory-address of the computer which stores the color-formula for that can and other infromation. The computer operating system controls the guidance of the particular paint can along its conveyance, so that the paint can is designated to one of a plurality of paint-batching cells of the system of the invention, with the bar-code of the paint can being read at a plurality of stations along the entire manufacturing process.

摘要:
The invention deals with continuous process mixing of pulverized solids and liquids. It offers a mixing process comprising:continuously introducing a liquid into a mixing container;continuously introducing a solid powder into said container at such a rate that specified proportions of solid and liquid in the mixture are maintained;rotating the products in the container in such a way as to establish a vortex;regulating the solid and liquid supply rate in such a way that a given level of filling of container is constantly maintained;continuously emptying the products mixture so that level of filling is maintained.It offers as well a mechanism to implement the process including a mixing container having an intermediate bottom and a runoff opening, a turbine mounted above the intermediate bottom, and mechanism for supplying a liquid and a solid. Advantageously, the liquid is used to wash down the walls of the mixing container and may be applied to parts of the turbine to avoid retention of solids in the container. It can be applied to hydraulic binders preparations and specifically to continuous process preparation of a plaster and water mixture.
