Continuous mixing in a static mixer possible can be used to add one kind of particles (such as an enzyme granular product) in a small amount to a larger amount of a different kind of particles (such as a powder stream of detergent powder), even if the powder characteristics are substantially different, with substantially no damage to the enzyme particles and with a high degree of homogeneity.

Herein is reported a feed mixing device for adding feed solutions with a non-physiologically pH value to a cell cultivation vessel comprising a chamber for mixing the feed solutions prior to their addition to the cell cultivation vessel as well as its use. With the feed mixing device as reported herein feed components can be provided in solution at a pH value at which they have good solubility and/or good stability whereby the pH value can be clearly different from the pH value of the cultivation medium, i.e. different from the physiological pH value. This allows performing the cultivation with more flexibility compared to a cultivation in which the pH value of the feed solution is limited to a small range around the pH value of the cultivation.

Disclosed are various embodiments of a rocker-style treatment tank equipped with instrumentation. In one embodiment, a rocker treatment tank includes a dasher configured to oscillate within treatment liquid in the rocker treatment tank. The dasher includes a dasher shaft, one or more dasher arms coupled to the dasher shaft, and at least one dasher blade coupled to the dasher arm(s). The rocker treatment tank also includes one or more sensors configured to provide data directly or indirectly indicating a torque transmitted to the dasher to effect oscillation.

The present invention relates to a method and an arrangement for dissolving starch. Specifically, the present invention relates to a method for dissolving starch by introducing mechanical force to at least partially gelatinized agueous starch.

An exhaust gas turbine (30) for expanding exhaust gas, comprising a turbine housing (33) having an inflow housing portion (35) for exhaust gas to be expanded and an outflow housing portion (36) for expanded exhaust gas, a turbine rotor (34) received by the turbine housing (33), the turbine rotor (34) being rotatable about an axis of rotation, a metering means (42) for a reducing agent or a precursor substance of a reducing agent, wherein the reducing agent or the precursor substance can be introduced into the expanded exhaust gas via the metering device (42), and with a swirl atomizer (43), rotating together with the turbine rotor (34), for the reducing agent or the precursor substance, the reducing agent or the precursor substance being atomizable in the expanded exhaust gas via the swirl atomizer (43), the swirl atomizer (43) engaging the turbine rotor (34) at a downstream, hub-side portion of the turbine rotor (34). Downstream of the turbine rotor (34) in extension of the axis of rotation of the turbine rotor (34), an impingement body (44) is arranged for the reducing agent or the precursor substance introduced into the exhaust gas and atomized, wherein a distance of the impingement body (44) from the swirl atomizer (43) corresponds to at most 7 times a diameter of the turbine rotor (34).

A mixing assembly includes a main flow conduit having an inlet end and an opposite outlet, a source of pressurized air at the inlet end, a container of stucco in fluid communication with the flow conduit, and a source of water in fluid communication with the flow conduit between the outlet and the container. The pressurized air draws stucco from the container into the flow conduit, and also draws water into the flow conduit to form an atomized slurry.

Embodiments of the present application relate to compositions bupivacaine multivesicular liposomes (MVLs) prepared by a commercial manufacturing process with large particle diameter span.

The subject matter of this specification can be embodied in, among other things, a mixing system that includes a heating assembly configured to heat liquid, and a mixing assembly including a tank defining a cavity and configured to retain liquid, an inlet in fluidic communication with the cavity and configured to receive liquid from the heating assembly, a mixing impeller assembly configured to mix contents of the cavity, an actuator configured to actuate the mixing impeller assembly to mix contents of the cavity, and an outlet in fluidic communication with the cavity and having a valve configured to selectively prevent and permit egress of contents of the cavity.

A spray atomizing ozone water generating apparatus with gas storage ability includes a gas-water mixing chamber with atomizing water nebulizer, a delay circuit, as well as a tap water inlet valve and an ozone water outlet valve controlled by the delay circuit. Because the mixer has ozone storage ability, atomizing water nebulizer will atomize tap water sufficiently, ozone water generating apparatus according to the invention can thus produce super high concentration ozone water having a concentration more than 30 ppm.

Embodiments of the present application relate to commercial manufacturing processes for making bupivacaine multivesicular liposomes (MVLs) using independently operating dual tangential flow filtration modules.
