The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done batchwise such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.

An automated apparatus for preparing a liquid bioprocess solution includes at least one mixing chamber having a lower port and an upper port for fluid to enter the at least one mixing chamber, an array of tubing for fluid flow within the system, a plurality of valves provided within the tubing, and a mixing controller configured to cause the automated apparatus to perform a series of sequential mixing steps causing the preparation of the liquid bioprocess solution from a dry ingredient. The series of sequential mixing steps include opening a first valve associated with the lower port to provide fluid to the at least one mixing chamber through the lower port, and after a predetermined amount of elapsed time, closing the first valve and opening a second valve associated with the upper port to provide fluid to the at least one mixing chamber through the upper port.

The present disclosure relates to a system, generator and method for generating nanobubbles or nanodroplets and treating a multi-component mixture, and in particular for treating biogas and wastewater. The method comprises using nanobubbles of a gas component, and wastewater, to form hydrates in a treatment vessel; removing residual dirt from the treatment vessel and melting the hydrates to facilitate release of clean water.

A fuel pump for a liquid fuel water injection system of a motor vehicle is provided. The fuel pump includes a low-pressure pump that mixes water from a water tank of the motor vehicle with liquid fuel from a fuel tank of the motor vehicle to a liquid fuel water emulsion and provides the liquid fuel water emulsion at a low pressure. A high-pressure pump is in fluid communication with the low-pressure pump and compresses the liquid fuel water emulsion from the low pressure to a high pressure for injecting the liquid fuel water emulsion into an internal combustion engine of the motor vehicle via an injection rail of the motor vehicle. A pump drive drives the low-pressure pump and the high-pressure pump synchronously with a pump frequency independently from an engine speed of the internal combustion engine of the motor vehicle.

The present invention relates to systems and methods for manipulating droplets within a high through put microfluidic system.

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

Provided herein are containerized liquid formulations comprising a plurality of agrochemicals. The formulations comprise a plurality of parallel liquid layers, wherein each layer is disposed within the container such that it is in contact with at least one adjacent layer at an interface. Also provided are methods of preparing, storing, shipping, and using the containerized liquid formulations.

A system for controlling an emulsification process including the steps of acquiring images such as micrographs of an emulsification process at preset intervals between a start and an end of the emulsification process; detecting selected droplet characteristics such as size and count using image segmentation such as a histogram-based technique; analyzing the measured droplet characteristics; comparing the measured droplet characteristics with a desired droplet characteristic specification; and terminating the emulsification process when said desired droplet characteristic is achieved.

Provided is a highly efficient pipe-type flocculation mixer, comprising: a feeding pipe, a mixing pipe, a discharging pipe and a mixer. The feeding pipe, the mixing pipe and the discharging pipe are disposed in parallel and sequentially communicated. The mixing pipe is a circular pipe and has two blind ends. The mixer comprises a driving motor, a mixing blade and a central shaft. One end of the central shaft is coupled to the driving motor, and another end of the central shaft is coupled to the mixing blade. The size of the mixing blade enables the mixing pipe to exactly accommodate the mixing blade. Also provided is a feeding-mixing device, wherein an agent can be introduced into a hollow central shaft via an agent feeding chamber, and be sprayed out from the central shaft into a mixing chamber; said agent feeding manner enables sufficient mixing.

A mixer apparatus for mixing a high-viscosity fluid has a mixer shaft with a plurality of blades affixed thereto, a hydraulic motor drivingly connected to the mixer shaft so as to rotate the mixer shaft, a hydraulic pump connected by a fluid circuit to the hydraulic motor so as to deliver hydraulic fluid under pressure to the hydraulic motor, an electric motor drivingly connected to the hydraulic pump, and a hydraulic fluid reservoir connected to the fluid circuit so as to supply hydraulic fluid to the hydraulic pump. The plurality of blades are pivotally mounted to the mixer shaft.
