A mixing unit includes a mixing body having mixing elements that are stacked in a stacking direction and that extend in an extending direction in which the extending direction is perpendicular to the stacking direction. The mixing elements have a plurality of through holes to form a flow path therein, and are arranged such that part or all of the through holes in one of the mixing elements communicate with through holes in the adjacent mixing elements to allow fluid to be passed in the extending direction in which the mixing elements extend. The mixing unit may be employed in an agitation impeller or an adhesive dispensing unit.

The occurrence of separation or reaggregation is suppressed in a suspension such as a battery electrode slurry. A battery electrode slurry distributing apparatus includes: a circulation pipe via which a positive electrode slurry is to be circulated; and a control unit that controls the supply of the positive electrode slurry to each of coaters. In a period in which either the coater is allowed to receive the supply of the positive electrode slurry, the control unit inhibits the supply of the positive electrode slurry to the other coater. The circulation pipe is structured in a polygonal loop. The coaters are connected to respective elbow portions formed in the circulation pipe via the pipes, respectively.

The invention relates to a method for manufacturing a liquid acid concentrate for hemodialysis machines, with the following steps. In a preliminary step a water source (120), an acid source (130), an electrolyte tank (140) containing a mixture of electrolytes in exactly the quantity needed for the manufacture of the liquid acid concentrate, and a sodium chloride source (150) are connected to a mixing tank (110). During Step a), the quantity of water needed for the manufacture of the batch of liquid acid concentrate is introduced into the mixing tank (110). At Step b), the quantity of acid needed for manufacture the liquid acid concentrate is introduced into the mixing tank (110), the solution is stirred until a homogeneous solution is obtained. Step c) is to repeat Sub-steps c1) and c2) until the electrolyte mixture contained in the electrolyte tank is completely dissolved. At Sub-step c1) part of the solution contained in the mixing tank (110) is transfered into the electrolyte tank (140) containing the electrolyte mixture, then at Sub-step c2) the solution contained in the electrolyte tank (140) is transfered into the mixing tank, leaving the still solid constituents in the electrolyte tank. At Step d) the quantity of sodium chloride needed to manufacture the liquid acid concentrate is introduced into the mixing tank (110). Finally, at Step e), the solution is stirred and recirculated by taking it from the bottom the mixing tank (110) and reintroducing it at the top of the mixing tank until a homogeneous liquid acid concentrate is obtained. Steps a) to d) can be performed in any order, Step a) preceding always Step c).
