A method in which a stream of dry cementitious powder from a dry powder feeder passes through a dry cementitious powder inlet conduit to feed a first feed section of a fiber-slurry mixer. An aqueous medium stream passes through at least one aqueous medium stream conduit to feed a first mixing section the fiber-slurry mixer. A stream of reinforcing fibers passes from a fiber feeder through a reinforcing fibers stream conduit to feed a second mixing section of the fiber-slurry mixer. The stream of dry cementitious powder, aqueous medium stream, and stream of reinforcing fibers combine in the fiber-slurry mixer to make a stream of fiber-cement mixture which discharges through a discharge conduit at a downstream end of the mixer.

Disclosed in an embodiment of the present application is a mixing apparatus, mixing machine, and cooking utensil. A mixing apparatus that can be fitted to an electric motor assembly. The electric motor assembly is able to drive the mixing apparatus to rotate for mixing food ingredients. The mixing apparatus comprises a connection part, stirring rods extended from the connection part and stirring bars. The positions at which the stirring bars are fitted to the stirring rods can be adjusted based on the type and quantity of food ingredients to increase mixing uniformity.

A mixing device includes a base, shaft, impeller sleeve, and impeller blades. The base can be constructed for releasable attachment to an opening of a container, such as a 55-gallon drum. The shaft extends from the base and is coupled thereto such that rotation can be transmitted to the shaft by way of or through the base. The impeller sleeve is mounted on the shaft and supports the impeller blades. Each impeller blade includes an attachment leg and a stirring leg extending from the attachment leg. The impeller blades are supported so as to transition from a collapsed position with the stirring leg proximal to a central axis of the shaft to an extended position with the stirring leg distal from the central axis when the shaft is rotated. Each impeller blade can be formed of a plastic, such as a glass-filled polypropylene or glass-filled nylon.

A mixing apparatus and system includes a hub, a plurality of blades, and a respective hinge for each blade to pivotally secure each blade to the hub. Each hinge including a lock having a tab and a detent to secure the respective blade in an operating conformation.

A bioreactor (30) for production and harvesting of microalgae is described, comprising a reactor basin (32) in the form of a tank arranged to receive CO2 and water as well as algae, and which is equipped with at least one outlet for harvesting of algal biomass, where the reactor basin (32) comprises a rotating beam (54) equipped with one or more tillable mixing grates (60) and harvesting grates (62).

A method of mixing a fluid includes at least partially unfolding a collapsible bag bounding a compartment, the collapsible bag containing in the compartment at least a portion of an elongated drive line or drive shaft and an impeller secured to the drive line or drive shaft, the impeller including a plurality of impeller blades that are pivotable relative to the drive line or drive shaft, at least one of the plurality of impeller blades being in a collapsed position. A fluid is delivered into the compartment of the collapsible bag. The drive line or drive shaft is then rotated so as to rotate the impeller within the compartment and mix the fluid therein, the at least one of the plurality of impeller blades pivoting from the collapsed position to an expanded position as the impeller is rotated within the compartment.

A folding impeller formed around a central hub. The folding impeller has a plurality of impeller blades each formed with a leading portion that is extended from a trailing portion, with the leading and trailing portions of the blade and including an obtuse angle therebetween. The trailing portion of each blade is mounted for tangential rotation about the hub between a folded state and a spread state, wherein in the folded state an axis of the hub lies within the angle included between the leading and trailing portions of each of the impeller blades, and wherein in the spread state each blades is tangentially extended from the hub with the included angle being arranged transverse of the axis of the hub, and wherein the trailing portion is arranged substantially parallel with the axis, and the leading portion forms an angle of attack therewith.

The present disclosure relates to a blender having blades whose orientation angle is changeable, even while the blender is in operation. The blender 100 includes a housing 110 with inlets (140a, 140b) to allow inflow of ingredients and an outlet (140c) to allow outflow of blended ingredients. The blender 100 incorporates an external shaft 122 with the blades 123 rotatably coupled to it, and an internal shaft 121 inside the external shaft 122. The blender 100 incorporates a first driving unit 130 to rotate the external shaft 122 and blades 123 about a direction along a length of the housing 110 to allow blending of the ingredients. The internal shaft 121 having engaging means coupled to back of the blades 123 such that a linear displacement of the internal shaft 121 using a second driving unit 121, enables change in orientation of the blades 123.

In a food processing device, an adjustable food processing tool includes a central hub having a fixed blade and an articulating blade extending outwardly therefrom. The articulating blade is adjustable relative to a pitch of the blade between substantially vertical and horizontal positions. An external adjustment assembly is disposed on a base unit of the food processing device for adjusting the pitch of the articulating blade, wherein the pitch of the articulating blade can be adjusted while a food processing procedure is being conducted. The adjustable food processing tool is configurable between a chopping configuration and a stir configuration, thereby providing for a single food processing tool that can be used for a multitude of food processing functions.
