Provided are methods and devices for dissolving solid protein compositions, such as solid compositions comprising fibrinogen, in an aqueous solvent. The methods comprise use of a closed container containing a volume of solid fibrinogen composition and a head space wherein the pressure within the headspace is sub-atmospheric. Aqueous solvent is introduced into the container while maintain the sub-atmospheric pressure, and subsequent to addition of the solvent, the size of the headspace is decreased to bring the pressure to atmospheric pressure. The devices are suitable for use in the disclosed method.

Systems for managing abrasive media in cavitated fluid include a set of sensors in communication with cavitated fluid in a processing tank and a processor coupled to the set of sensors. The processor is configured to determine a density of an abrasive media in the cavitated fluid in the processing tank and facilitate maintaining the density of abrasive media in the cavitated fluid in the processing tank at a level that is greater than or equal to a threshold level of abrasive media. The processor is further configured to command the abrasive media addition device to add the recycled abrasive media to the processing tank to increase the density of abrasive media in the cavitated fluid in response to determining that an average density of abrasive media is less than the threshold density of abrasive media.

An agricultural incline conveyor having belt guards extending longitudinally through a curvilinear portion from a tail inlet to a head outlet. The belt guards protect linear edges of a belt within the curvilinear portion during mixing operations. A plurality of mixing baffles positioned within the curvilinear portion induce turbulent backflow of a metered stream of seed being transported through the curvilinear portion. The longitudinal guards prevent the loss of transported seed from entering between the belt and a trough of the curvilinear portion.

A vacuum assembly includes a vacuum portion having a vacuum source with an inlet and an outlet and a tank portion. A three-way inlet valve fluidly connects the inlet to the vacuum source with the tank portion when in a first position and fluidly connects the inlet to the vacuum source with an inlet to a surrounding environment when in a second position. A three-way outlet valve fluidly connects the outlet of the vacuum source with an outlet to the surrounding environment when in a first position and the outlet of the vacuum source with the tank portion when in a second position.

A dual chamber assembly for continuously injecting slurry into a wellhead by displacing it from chambers with pressurized clean fluid.
