Abstract: A liquid-feeding chip for feeding a liquid utilizing the action of centrifugal force and gravity by rotating the chip around an axis of rotation, includes a first storage tank (1-1) into which the liquid can be introduced when rotation of the chip is stopped, and two or more liquid-feeding units arranged in a plurality of levels adjacent to each other, each liquid-feeding unit (U-1, U-2, U-3) being composed of a first holding tank (10-1, 20-1, 30-1), a second holding tank (10-2, 20-2, 30-2) positioned in the direction of gravity with respect to the first holding tank, and a channel B(B-1, B-2, B-3) which extends from the first holding tank in the direction of gravity and which connects the first holding tank and the second holding tank, the first holding tank at a first level being connected with a channel A(A-1) which extends from the first storage tank toward an outer circumferential side. In the liquid-feeding chip, the adjacent liquid-feeding units are connected by a channel C (C-1, C-2) which extends from the second holding tank of the liquid-feeding unit at an upper level to an outer circumferential side during rotation, and which is in communication with the first holding tank of the liquid-feeding unit at a lower level.

Abstract: In a process of producing a sugar liquid from a woody biomass, the conventional techniques have such a problem that a specific component contained in the sugar liquid from the woody biomass remarkably deteriorates the filtration performance when the sugar liquid is filtrated through a microfiltration membrane and/or an ultrafiltration membrane. In the present invention, it becomes possible to improve the filtration performance of the sugar liquid through the microfiltration membrane and/or the ultrafiltration membrane, and it also becomes possible to produce the sugar liquid with high efficiency by hydrolyzing the woody biomass to produce a liquid component and then reacting the liquid component with a mannanase.

Abstract: Disclosed is a separating chip for separating an insoluble component from a suspension by using a rotating centrifugal force. The separating chip comprises a suspension holding bath, a separated liquid holding bath and an insoluble component holding bath, which are arranged sequentially in the recited order from the inner circumference side at the rotating time. The separating chip is constituted such that the suspension holding bath and the insoluble component holding bath are connected, such that the insoluble component holding bath and the separated liquid holding bath are connected by a narrow portion, and such that the portion of the insoluble component holding bath, as connected to the suspension holding bath, is positioned closer to the outer circumference side than the narrow portion.

The liquid-feeding chip comprises a first liquid-reserving bath (1-1) capable of introducing the liquid at a chip-rotation stopping time, and at least two liquid-feeding units (U-1, U-2 and U-3) individually including first holding baths (10-1, 20-1 and 30-1), second holding baths (10-2, 20-2 and 30-2) positioned in the gravitational direction of the first holding baths, and passages B (B-1, B-2 and B-3) extending in the gravitational direction from the first holding baths for providing the communications between the first holding baths and the second holding baths and arranged adjacently to each other in multiple stages such that the first holding bath of the first stage is connected to a passage A (A-1) extending from the first liquid-reserving bath to the outer circumference. The adjacent liquid-feeding units are connected by passages C (C-1 and C-2) extending from the second holding bath of the liquid-feeding unit of the upper stage to the outer circumference of the rotations and communicating with the first holding baths of the liquid-feeding unit of the lower stage.
