Abstract:
There is disclosed herein a frothing assembly (21) to froth milk in a container (11). The assembly (21) includes: a body (25); a motor (33) fixed to the body and having an output shaft (34) that is rotatably driven about a longitudinal axis (35) of the shaft (34); a frothing device (36) rotatably driven by the shaft (34) and to be submerged in the milk in the container (11); and a perforated member (43) at least partly surrounding the frothing device (36) and spaced from the frothing device (36) by a clearance (44), wherein rotation of the frothing device (36) causes movement of milk in the clearance (44) and movement of milk through the perforated member (43) to be circulated back through the container (11) and the clearance (44) to cause frothing of the milk.
Abstract:
A milking claw for efficiently drawing milk is disclosed. The milking claw includes a claw top and a claw bottom. The claw top includes a pair of front inlets, a pair of rear inlets, and an outlet. The front inlets and the rear inlets extend upwardly from a top surface of the claw top and are spaced on opposite sides of a longitudinal axis of the claw top. The outlet includes an air channel along a direction parallel to the longitudinal axis and a flow passage disposed below the air channel. The flow passage includes a horizontal portion and a vertical portion. The claw bottom is disposed below the claw top and includes a dividing wall, a sump, and a raised knob disposed within the sump.
Abstract:
In a method for deaerating a liquid the liquid is pressurized to a pressure above atmospheric, after which it is guided to an upstream end of a nucleation valve. A low pressure resides on the downstream end of the nucleation valve and as the liquid passes the valve, bubble nucleation is initiated, forming the first step in a deaeration process. According to the method the temperature and pressure on the downstream side of the valve is controlled such that the static pressure is above the saturation pressure, while the lowest pressure as the liquid passes the valve is below or equal to the saturation pressure.
Abstract:
The invention relates to a device for preparing milk froth that can be optionally hot or cold, or for dispensing optionally hot or cold milk (1), said device comprising a milk container (4) that can be removed from the device, a milk inlet which connects the milk container (4) to a cold froth device via a milk valve section, said cold froth device being activatable by means of an air valve section, and comprising an outlet line (15) that is located downstream of the cold froth device and comprises an outlet (16). The milk container (4) can be inserted into the device (1) in a guided manner and the base (4a) of said container is equipped with a milk snap-in valve (17). A complementary receiving section (17a) for the milk snap-in valve is fixed in the device (1) and is formed as a milk inlet directly on the milk valve section. When the milk container (4) is inserted, the milk snap-in valve (17) engages in the complementary receiving section (17a) for the snap-in valve and is locked therein.
Abstract:
A process for producing milk foam includes pumping milk through a milk line with a milk pump having an adjustable speed for adjusting the capacity of the milk pump. Milk from the milk line and air are mixed inside a first mixing chamber to produce a milk foam. Properties of the milk foam, including a consistency of the milk foam, are a function of the speed of the milk pump. A device for producing the milk foam includes a milk container; an outlet; a milk line connected between the milk container and the outlet; a first mixing chamber installed in the milk line to mix milk and air to produce milk foam; and a milk pump having an adjustable speed coupled into the milk line.
Abstract:
Tunnel is provided for conditioning of food products, especially for sterilization of food in containers or vessels of the heat-sealed type, in which the conditioning unit has: 1) an active temperature and pressure control system provided in at least one magnetron supported heating stage, which provides for balancing of the pressure within the heat-sealed vessels or containers; 2) a conveyor which conveys the heat-sealed vessels or containers through the stages along the conditioning unit which contains mechanisms that move the conveyor outside of the conditioning tunnel, and 3) doors operating like check valves that separate the conditioning stages, but still provide for continuous linear feed of products through conditioning tunnel. Movement of the magnetron electromagnetic field and/or conveyor is controlled by software which utilizes the temperature and/or density measurements in a closed loop process to ensure uniform heating of the products.
Abstract:
Disclosed are apparatus for delivery of a gas, e.g., carbon dioxide and/or chlorine dioxide, and methods of its use and manufacture. The apparatus includes a sachet constructed in part with a hydrophobic material. The sachet contains one or more reactants that generate a gas in the presence of an initiating agent, e.g., water. The apparatus can also include a barrier layer and/or a rigid frame. In another embodiment, the apparatus is combined with a reservoir that can be used to deliver a gas to the reservoir and, optionally, a conduit. In another embodiment, the apparatus is incorporated into a fluid dispersion system that includes a dispersion apparatus, e.g., a humidifier.
Abstract:
An method for processing a fluid, having a vacuum chamber having an associated heater, to heat a condensable gas therewithin, a spray nozzle to atomize a cool fluid, having a non-condensible gas dissolved therewithin, a vacuum line to maintain reduced pressure in the vacuum chamber and remove non-condensing gas, and a control, for maintaining steady state conditions in the vacuum chamber by controlling pressure and temperature conditions. Gases condenses on the atomized droplets to release a latent heat of vaporization.
