Equipment and procedure for extraction of solids from contaminated fluids whose basic purpose is to obtain the crystallised solids from the contaminated fluids, without any type of rejection in order to valorize them and to obtain purified water in a single stage, all in a continuous adiabatic/sonic process with evaporation/crystallisation and with low energy consumption and where the procedure is characterised by being constituted basically by at least three circuits fully interconnected as a single piece of equipment where the first circuit, the principal circuit, is constituted by an inlet duct of the contaminated fluid to be treated (1) followed by a pre-filter (2) followed by a filter for fine particles (3), a heat exchanger of preheated contaminated fluid (5) in the heat exchanger (4), followed by a fluid feedback pump (6) to a nozzle formed by an injector (7) and an ejector (8), which introduce the fluid to an evaporation chamber (9), where the steam that exits is introduced into a closed-loop electromagnetic servomechanism (26), an saturated steam ejector outlet (32), driven to the heat exchanger (4), outlet (13) as purified water from the saturated steam (22).

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.

Embodiments of the present disclosure include, for example, systems, apparatuses, devices, and methods for producing a population of particles. In some embodiments, such particles include particles corresponding to an active, pharmaceutical ingredient.

Disclosed are apparatus and methods for sampling air-borne particles. According to one embodiment a nozzle is used to generate a jet of fog that includes a gas and liquid droplets of different sizes. The jet of fog is formed by the nozzle in a way to cause particles in the air surrounding the jet of fog to be drawn into the jet of fog and to further cause the particles to aggregate with the liquid droplets inside the jet of fog. A sample collecting surface is located opposite and spaced apart from an outlet of the nozzle. The sample collecting surface is preferably sloped so that the liquid sample can be forced by gravity off the collecting surface and into a vial or other liquid sample container. Inside the jet of fog and on the sample collection surface the liquid droplets merge with one another to form larger sized droplets that are collectable in the liquid sample container.

A rotary atomizer comprises an electric motor having a stator and a rotor, a vertical shaft, one or more porous gas bearings configured to provide frictionless radial and axial support to the shaft, and a rotating disc installed at a lower end of the shaft, said rotating disc configured to spray liquid into the form of fine particles. A gap detection system monitors a distance between the porous gas bearings and the vertical shaft. Bushings on the motor housing help to maintain precise alignment of the rotor during installation and maintenance.

An electrostatic spray dryer for drying liquid into powder including an elongated cylindrical drying chamber having an electrostatic spray nozzle at an upper end and a powder collection vessel at a lower end. The powder collection vessel includes a removable and replaceable filter collections sock made of filter material for receiving and collecting dried powder from the drying chamber. For cleaning residual powder from an inside wall of the drying chamber, a scraper member is provided that is coupled by magnetic attraction to a manually removable driver on the external surface of the wall.

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The methods include use of a reactor vessel to degum, rinse, and dissolve the silk fibroin protein from silk inputs to obtain a food grade silk powder. The reactor vessel may include a combination of inputs and outputs for introducing and removing different components used or generated during the process. The systems may include any combination of heat exchangers, holding tanks, filtration modules, and post-treatment equipment as necessary to obtain the silk powder. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.
