A device for pastillating a flowable product, in particular a melt. The device has a revolving belt and a drop former, and the drop former deposits product drops on an upper run of the belt. The product drops, in the course of transportation on the upper run of the belt, solidify to form pastilles, and an arrangement for wetting the belt with a liquid release agent is provided upstream of that region in which the product drops are deposited on the belt. The release agent prevents or reduces the adhesion of the product drops to the belt, and a proportional metering pump is provided for continuously mixing the release agent from at least two liquid components during the operation of the device.

A dilution control device and method of operating the same. The dilution control device can include a structure for dispensing concentrate and diluent fluid in a desired dilution ratio utilizing volumetric dosing. In some embodiments, diluent fluid drives a wheel or compresses a pliable concentrate bag in order to dispense concentrate in the desired ratio with the diluent fluid. In some embodiments, one or more floats can be used to drive a pump or actuate a valve to dispense concentrate at a particular rate proportional with the flow rate of the diluent fluid. In some embodiments, a rocker is responsive to the flow of diluent fluid to pump concentrate. In some embodiments, the dilution control device can be operable to automatically modulate the dispense rate of concentrate when the diluent fluid flow rate is varied in order to maintain a predetermined dilution ratio.

A fluid arrangement (10) for continuous delivery of volumetrically proportioned gases or like fluids includes a valve assembly (11) and a volumetric fluid storage bank (143), which has first and second sets (144, 151) of fluid storage chambers (145, 148, 152, 155). The valve assembly (11) alternately supplies a consumer with a blend of gases from the first set (144) of fluid storage chambers while charging the second set (151) of fluid storage chambers from pressurized gas sources (158, 159), and, upon a threshold depletion of gases from the first set (144) of chambers, supplies the consumer with a blend of gases from the second set (151) of fluid storage chambers while charging the first set (144) of fluid storage chambers from the gas sources (158, 159). The valve assembly (11) again supplies mixed gases from the first set (144) of chambers while charging the second set (151) of chambers.

Aspects of the disclosure provide methods, apparatuses, and systems for providing variable strength mixtures of fluids. In an aspect of the disclosure, a fluid combining device allows for the relative volume of a first liquid to be varied with respect to a total volume of fluid being delivered to a user (such as a combination of two or more liquids), which in turn changes the fluid ratios.
