A grain food product washing and hydrating system includes a mass-flow designed vessel. The vessel includes an upper wash section in the form of a cylinder. The wash section receives the grain food product and mixes the same with a fluidized liquid in a turbulent flow. Excess fluid is recycled. The washed grain food product then moves towards a frustoconical-shaped hydration section, where a treated liquid hydrates the grain food product. The shape of the hydration section allows for the mass-flow movement of the grain food product, which ensures continuous flow and enough residence time to hydrate the grain food product, before metering out the same for further processing.

A modified distiller's, a preparation method thereof, and a use thereof are provided, which relate to the field of composite material preparation. Coupling agents with different reactive groups and hyperbranched resins with different terminal reactive groups are used, and through synergistic effect of the coupling agent and the hyperbranched resin, the surface of distiller's grains powder is regulated. This approach solves problems of poor interfacial compatibility between the distiller's grains powder and the biodegradable resin, as well as agglomeration of the distiller's grains powder due to strong hydrogen bonding. As a result, the compatibility and interfacial bonding strength between the distiller's grains powder and the biodegradable resin are enhanced, leading to the production of a high-performance fully biodegradable green composite material.
