A device for mixing liquid material which a user shakes by hand up and down or left and right is provided. The device includes: a container that includes a space on an inner side extending in the longitudinal direction, and a grip shape on an outer side of the container; an opening-closing member; and a coil spring which has a constant winding diameter and moves freely inside the container in the longitudinal direction. Liquid material and the coil spring are contained in the container, the liquid material being obtained by mixing a material to be dispersed and liquid. A silencer is provided at the end of the coil spring. The device includes: a coil spring abutting part that abuts against and supports 80% of a planar spread formed by one winding of an end of the coil spring relative to the one winding; a first vertical wall and a second vertical wall which are two vertical walls which are perpendicular to the coil spring abutting part and also perpendicular to the coil constituting the coil spring, and are provided at limiting positions where the coil spring of the coil spring abutting part abuts; and a cylindrical wall that extends vertically opposite to the coil spring of the coil spring abutting part, and has an inner diameter set to be the outer diameter of the coil spring, wherein the first vertical wall and the second vertical wall each have two holes through which a coil constituting the coil spring can pass arranged side by side in a direction in which the coil spring extends.

With a method for heating in particular milk or milk foam, in which the milk or the milk/air mixture is conveyed through a passage opening and hot steam is conveyed through at least one steam line transversely into this passage opening. The passage opening and the at least one inlet opening opening transversely into the steam line, the steam pressure in this and the pressure and the pressure in the passage opening with flowing milk or milk/air mixture are so coordinated that the hot steam at the at least one transverse inlet opening condenses in the passage opening directly on contact with the milk or the milk/air mixture. Consequently the additional energy produced by the phase change from steam to condensate water is transmitted directly as heat to the heat in the milk or the milk/air mixture.

An apparatus includes a housing with an inlet for a pasty product to be aerated and an outlet for the aerated product. The apparatus includes at least a first set of a rotor and a stator and a second set of a rotor and a stator. The apparatus further includes a gas injector for injecting, upstream of the first set of the rotor and the stator, a gas into the pasty product to be aerated. The apparatus further includes an intermediate mixing chamber provided in the housing between the first and the second sets of the rotor and the stator . A secondary product introduction member protrudes into the intermediate mixing chamber so as to issue into the intermediate mixing chamber. A method for aerating a pasty product is also provided.

A gas-saturated liquid generator having a vessel of the generator, a hollow bell in its upside down position located with a tube for gas supply, and a mixer situated in the area for saturated liquid covered by the bell is disclosed. The entire bell is submerged below the surface of the saturated liquid. On a shaft projecting from a driving equipment, the mixer provided with a foaming spring is situated. The mixer provided with a magnetic carrier seated rotatably on the protrusion formed by a bulge in the bottom part of the generator vessel may be used.
