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.

The invention relates to a method for controlling at least one first circulation pump (17b, 17c) of a heating or cooling system (1) having a primary circuit (2, 2a) and a secondary circuit (4, 30a) coupled therewith at a transfer point (3, 29). The first circulation pump (17, 17b, 17c, 17b) conveys a heating or cooling medium in the primary circuit (2, 2a), and in the second secondary circuit (4, 30a), at least one second circulation pump (12, 17d) is located that conveys a heating or cooling medium in at least one partial area of the secondary circuit (4, 30a). The volume flow rate (formula I) of the first circulation pump (17, 17b, 17c, 17b) is controlled in functional dependence on the volume flow rate (formula II) of the secondary circuit (4, 30) behind the transfer point (3, 29). In this way, a demand based, and thus an energy-efficient control of the primary-side circulation pump is achieved. The invention further relates to a pump system, comprising the at least one first and the at least one second circulation pump for carrying out the method.

A fermentation and aging apparatus may include a tank, a fermentation container, an ingredient accommodator having at least a portion of ingredients for making a beverage accommodated therein, a pump, and a controller that controls the pump such that the portion of ingredients accommodated in the ingredient accommodator may be introduced into the fermentation container while the beverage is made. The controller may control the pump according to a primary fluid supply operation of turning on the pump to introduce fluid accommodated in the tank into the ingredient accommodator and to introduce the fluid and the portion of ingredients into the fermentation container, an operation of turning off the pump during a predetermined idle period, and a secondary fluid supply operation of turning on the pump to introduce the fluid accommodated in the tank into the ingredient accommodator and to introduce ingredients remaining in the ingredient accommodator and the fluid into the fermentation container.
