The present invention refers to an interchangeable device comprising: a high-pressure pump unit (16002), a water intake (16003), and a lance (16005), characterized by a coupling system comprising: a shaped shaft (16001)-shaped hub (16007) coupling, an anti-rotation positioning element (16008), and a locking clamp (16009), wherein the coupling system allows a power generator of varying type (16006) to be coupled, rendering the device a high-pressure washer and/or a high-pressure sprayer.

An apparatus for converting a dry material into a liquid concentrate includes a mixing vessel having an outlet opening, a dispenser for dispensing a predetermined weight of a dry material at a predetermined drop rate onto a predetermined drop location within the vessel, an inlet pipe connectable to a source of liquid for introducing a liquid into the vessel; a sensor for sensing the volume of liquid within the vessel; a pump for supplying a pressurized flow of recirculating liquid to the vessel; and a first, a second and a third agitating nozzle mounted within the vessel. Each agitating nozzle is operative to produce a jet of liquid oriented in a predetermined direction within the vessel. The nozzles are cooperable to generate within the vessel a moving body of liquid into which a dry material dispensed into the vessel is able to dissolve or to disperse.

A batch preparation system for quickly and efficiently mixing materials with a fluid, such as to fill an agricultural reservoir tank. The batch preparation system generally includes a frame, a tank unit comprising a plurality of tanks connected to the frame, and a transfer system for mixing materials stored in the tanks with fluids being pumped from a fluid source. The tanks are interconnected to form a unitary tank unit which is positioned on the frame. The transfer system includes a manifold pipe which is fluidly connected to each of the tanks. An eductor is connected to the manifold such that the materials from each tank are drawn by suction through the eductor into a mixing conduit, where the materials are mixed with the fluid from the pump. The resulting mixture is dispensed through a transfer outlet, such as to a reservoir tank.

Devices, systems and methods for mixing and/or introducing agrochemicals, comprising a mixer including a mixing chamber in which a liquid is able to flow, and a delivery point located on the mixing chamber for delivering an agrochemical into the mixing chamber, wherein the mixer includes means for generating backpressure in the liquid and the agrochemical in the mixing chamber, and a mixer system including a mixer, an injector, and an agrochemical source, wherein the injector is adapted to receive an agrochemical from the agrochemical source, and a method including the steps of supplying a liquid into a mixing chamber of a mixer or mixer system, delivering an agrochemical into the mixing chamber, and generating backpressure to the liquid flowing through the mixing chamber to effect mixing of the liquid and the delivered agrochemical.

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.

There is provided a mixing device. The mixing device comprises a first branch (7) to provide a first substance from a source (3). The mixing device further comprises a reservoir (9) for storing a second, additive substance, the reservoir (9) comprising an inlet (18) for receiving the first substance from the first branch (7). The mixing device further comprises a swirl generator (18A) configured to impart swirl in the first substance entering the reservoir (9) from the first branch (7). The mixing device further comprises a second branch (5) to output a mixture of the first substance and the additive substance from an outlet (17) of the reservoir (9), or the reservoir comprising a vent outlet (17) to output a mixture of the first substance and the additive substance.
