Apparatuses and methods that reduce cavitation in interaction chambers are described herein. In an embodiment, an interaction chamber for a fluid processor or fluid homogenizer includes an inlet chamber having an inlet hole and a bottom end, an outlet chamber having an outlet hole and a top end, a microchannel placing the inlet hole in fluid communication with the outlet hole, wherein an entrance to the microchannel from the inlet chamber is offset a distance from the bottom end, and at least one of: (i) a tapered fillet located on a side wall of the microchannel at the microchannel entrance; (ii) a side wall of the microchannel converging inwardly from the inlet chamber to the outlet chamber; (iii) a top wall and/or bottom wall of the microchannel angled from the inlet chamber to the outlet chamber; and (iv) a top fillet that extends around a diameter of inlet chamber.

An improved method for the manufacture of an oil-in-water emulsion involves circulation of emulsion components between a first container and a second container via a homogenizer and/or via a microfluidization device. Usefully, all of the emulsion components from the first container are emptied before being returned.

A liquid sampling container with an internal mixer includes a sealed outer body configured to hold a sample multi-phase fluid obtained from a multi-phase fluid stream. An inlet line is attached to the outer body. The sample multi-phase fluid flows into the sealed outer body through the inlet line. A piston assembly is positioned within the sealed outer body. The piston assembly is sealed to the inner walls of the outer body to define a sample volume in which the sample multi-phase fluid is contained. A shear mixer is positioned within the sealed outer body. The shear mixer includes a rotor and a stator arranged to define a fluid passage and rotatable relative to each other. The rotor includes a rotary shear blade configured to shear the sample multi-phase fluid such that a homogeneity of multiple phases in the sample multi-phase fluid remains substantially constant.

The invention relates to a method for adding hops in beer manufacture, having the following process steps; a) separation of a sub-quantity (07a) of water and/or wort (07) and/or beer as an aqueous fluid, b) addition of hop extract (10) in liquid or pasty form to the separated aqueous fluid (07a), c) production of a macroemulsion (13) of the hop extract by emulsifying the hop extract (10) in the aqueous fluid (07a), d) increasing the pressure in the macroemulsion (13) of the hop extract to a feed pressure of in particular higher than 100 bar, e) production of a microemulsion (17) of the hop extract by feeding the pressurized macroemulsion (13) through a gap or a valve (16) or by feeding the pressurized macroemulsion against a baffle plate, f) at least partial return of the microemulsion (17) of the hop extract to the beer manufacturing process.
