PROBLEM TO BE SOLVED: To provide a display stand in which fresh fish and shellfish are subjected to freshness-keeping treatment with gas-liquid mixing treated water.SOLUTION: Nitrogen treated water in which treated water and a nitrogen gas are mixed or high-density oxygen treated water in which the treated water and an oxygen gas are mixed in high density is accommodated as the gas-liquid mixing treated water in a display tank for displaying the fresh fish and shellfish. The fresh fish and shellfish are displayed while being soaked in the gas-liquid mixing treated water.
Abstract:
PROBLEM TO BE SOLVED: To provide a mixing agitator which efficiently performs mixing and agitation to obtain a mixture.SOLUTION: A supply passage for supplying two or more kinds of fluid to be mixed and agitated is joined to a mixing agitating case which forms a mixing agitating chamber. A discharge passage for discharging mixed and agitated mixture is joined thereto. In the mixing agitating case, a rotary shaft joined to interlock with a rotating driving source is laid sideways, and a rotating side mixing agitating body is attached to the rotary shaft. A fixed side mixing agitating body is fixed to the mixing agitating case, to face the rotating side mixing agitating body, to form a mixing agitating flow passage extending in a meandering manner from a central part toward a peripheral part in a radiation direction between both mixing agitating bodies. An introduction port opened at a central part of the fixed side mixing agitating body communicates with the mixing agitating flow passage, and a deriving port formed between peripheral parts of both mixing agitating bodies communicates with the mixing agitating flow passage.
Abstract:
PROBLEM TO BE SOLVED: To improve permeability of dissolved CO into a piece of meat of fresh marine fish and shellfish.SOLUTION: The apparatus for producing smoke comprises a treated water supplying unit for supplying treated water as a solvent, a smoke supplying unit for supplying the smoke, a gas-liquid mixing treatment unit for mixing treatment of the treated water and smoke supplied from these supply units. The gas-liquid mixing treatment unit makes the gas-liquid mixed phase of the treated water and the smoke flow through a meandering channel, acts a high shearing force on the treated water forming clusters composed of some water molecules, produces modified treated water composed of the treated water with a smaller cluster size, and acting a high shearing force to the gas-liquid mixed phase of the modified treated water and the smoke to produce the smoke liquid by dissolving the smoke in the modified treated water which is a solvent.
