A reactor arrangement for performing, by means of at least one solid reaction member(s), a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media in a continuous process. The arrangement comprises at least one reactor with a cylindrical reaction vessel (11) in which at least one reactor a transformation device (100) has been mounted. The vessel (11) comprises at least one inlet port (30) in the vicinity of its bottom wall (18) and at least one outlet port (40) arranged in the vicinity of its upper end portion. Each inlet port (30) is connected to a fluid supply member (300) configured to be submerged below the fluid surface level in a pool or a pond. The fluid supply member (300) comprises at least one inlet opening (301) configured to continuously supply a fluid from the pool or the pond to the vessel (11). Each outlet port (40) is configured to continuously let out the fluid from the vessel (11) to the pool or the pond via the outlet port (40). Further a method of using the reactor arrangement is provided.

A storage vessel assembly for storing chemical includes a storage vessel, a frame for housing the storage vessel, an agitation device disposed in the storage vessel, a temperature control system coupled to the storage vessel, and a controller configured to operate the agitation device and the temperature control system.

A blending apparatus for coating product in flavouring is provided. The blending apparatus comprises a product dispenser configured to dispense a falling stream of product, a flavouring dispenser configured to dispense a falling stream of flavouring, and a deflection surface. The deflection surface is configured to deflect at least one of the falling stream of product and falling stream of flavouring, thereby bringing the falling stream of product and the falling stream of flavouring together. A method for coating product in flavouring is also provided. The method comprises the steps of dispensing a falling stream of product from a product dispenser, dispensing a falling stream of flavouring from a flavouring dispenser, deflecting the falling stream of product and the falling stream of flavouring using a deflection surface so as to bring the falling stream of product and the falling stream of flavouring together, thereby coating the product in the flavouring.

The invention relates to a preparation process of a modified polyamide wax for coatings and a formed coating. The coating includes 0.5-5 parts by weight of modified polyamide wax; the preparation process of the modified polyamide wax for coating includes the following steps: S1, ratio of raw materials:raw materials include water-based polyamide wax, water-based polyurethane, polyoxyethylene monostearate, the first composite modifier, organic amine, organic solvent, the second composite modifier, deionized water; S2, prepare the first complex; S3, add organic amine, organic solvent and the second composite modifier is evenly mixed, and the temperature is raised to 100-120 C. until the water-based polyamide wax is completely dissolved to obtain the first intermediate modifier; S4, deionized water is heated up and slowly added to the first intermediate modifier in the process. The coating system prepared by the invention has good leveling, stability and sag resistance.

An impeller assembly for a solid-liquid mixing device, and a solid-liquid mixing device using the impeller assembly. The impeller assembly comprises an impeller. The impeller comprises a truncated conical body. Multiple mixing blades are formed from top to bottom on an inclined surface of the body. The impeller assembly further comprises at least one blocking plate provided on an outer side of a lower portion of the body. The mixing device further comprises: a housing; at least one solid supply apparatus; at least one liquid supply apparatus; a mixing chamber defined by corresponding portions of the body and the housing; and a dispersion chamber provided between a flow channel outlet at a lower portion of the mixing chamber and a discharging apparatus.

A production method for a treatment solution for forming an insulating coating. The method includes mixing a solution A containing, on a PO.sub.4.sup.3 basis, 0.20 mol/L or more and 10 mol/L or less of at least one of (i) phosphoric acid and (ii) a phosphate salt, and containing, on a metal basis, less than 0.50 mol/L of one or more particulate metal compounds, and a solution B containing, on a metal basis, 0.50 mol/L or more and 20.0 mol/L or less of the one or more particulate metal compounds, and containing, on a PO.sub.4.sup.3 basis, less than 0.20 mol/L of at least one of (i) phosphoric acid and (ii) a phosphate salt, and stirring with a turbine stator-type high-speed stirrer such that a peripheral speed of a turbine reaches 10 m/s or more within 60 seconds after starting the mixing of the solution A and the solution B.

An impeller assembly for a solid-liquid mixing device, which includes an impeller body, multiple mixing blades which are evenly distributed on the inner side of the impeller body and extended outwards from the shaft of the impeller body, and at least two baffle plates being disposed on the outer side of the impeller body along a radial direction thereof outwards and disposed in the circumferential direction of the impeller body. At least one pair of adjacent two baffle plates satisfies following conditions: curves projected by two opposite surfaces of each of adjacent baffle plates on a cross section of the impeller at any height are smooth curves, and at least one of the curves is not fully included in a circle with the center of the shaft as its center.

With a method for digesting starch, an aqueous slurry of the starch is treated with steam in a cooking vessel and in this case exposed to shear forces, wherein the starch-containing slurry is heated to a temperature of between 85 C. and 110 C. in the cooking vessel by introducing steam, and the digestion step is implemented until the desired degree of digestion has been reached. Also described is a cooking vessel that can be used when the method for digesting starch is being carried out.

A stirring device of thin-film rotation type includes a tubular portion whose lateral surface has: a band-shaped first region extending circumferentially of the tubular portion and including holes penetrating in a inward-outward direction; and a band-shaped second region extending circumferentially of the tubular portion and including no hole or holes penetrating in the inward-outward direction, where the second region has a smaller aperture ratio than the first region. The first region is located to include a middle of the tubular portion in a height direction The second region ranges from the upper edge of the first region to the upper end of the tubular portion and also from the lower edge of the first region to the lower end of the tubular portion.
