The invention relates to a phycocyanin extraction method, which belongs to the technical field of biological medicine. The invention provides the phycocyanin extraction method for solving the current problems of long wall breaking period and large environmental pollution. The method comprises the following steps: adding phycocyanin-containing fresh algae or pre-immersed algae powder in ice powder at -50 to -10 DEG C, controlling the stirring speed at 1000r / min-3000r / min for wall breaking treatment to obtain a wall breaking liquid containing phycocyanin; separating and purifying the wall breaking liquid containing the phycocyanin, and drying to obtain the finished product phycocyanin. The method has the advantages of short wall breaking period and long friendly environment, and the product has the advantage of high purity.

The invention discloses a capsule beverage brewing device which comprises a water supply device and a brewing mechanism. The water supply device and the brewing mechanism are arranged in a casing. The water supply device comprises a water storage container and a heat dissipation device. The water storage container comprises an accommodating cavity and a heating device. The heating device heats water in the accommodating cavity to a set temperature. The heat dissipation device comprises cooling fins and a cooling fan. The cooling fins are arranged around the accommodating cavity, heat energy of the accommodating cavity is conducted to the cooling fins, and the cooling fan drives air flow to pass across the cooling fins. When the temperature in the accommodating cavity is lowrered to the set temperature, the cooling fan stops working, and at the time the heating device works discontinuously. Through arrangement of the cooling device, the water for brewing a capsule can achieve the sterilization effect and is always maintained at an optimal temperature, and it is guaranteed that the hygiene requirements and brewing effect in the capsule brewing process are met.

A disclosed centrifugation jet apparatus applied to sewage processing comprises a sewage inlet port, a throat port, a self-oscillation chamber, a throat path, a mixing chamber and a mixed-water outlet pipe which are successively connected from left to right; the internal diameter at the left part of the throat port is larger than the internal diameter at the right part; a position, close to a water inlet, at the left end of the throat port is provided with an air inlet, and the sewage inlet port is connected with the water inlet at the left end of the throat port; the self-oscillation chamber is in the shape of a concave body inverted to the right side, and a water inlet at the left side of the self-oscillation chamber is connected with the throat port; the middle part of the right side of the self-oscillation chamber is connected with one end of the throat path, and the other end of the throat path is connected with a water inlet of the mixing chamber; an ozone water inlet port is arranged beside the water inlet of the mixing chamber; and a water outlet at the right side of the mixing chamber is connected with the mixed-water outlet pipe. According to the centrifugation jet apparatus, a high-speed fluid is utilized to entrain a low-speed fluid for realizing supercharging and mixing processes, full uniform mixing of ozone water and sewage is guaranteed, and then the mixed water enters a reaction chamber for reaction, so that sterilization effect is realized, and the centrifugation jet apparatus is simple in structure and easy for operation.
