The invention discloses a high-purity fishy smell and foreign odor-free fish collagen protein peptide and a preparation method thereof. The preparation method comprises the following steps: cleaning fish skins, and then cutting into blocks and mincing; performing stirring treatment with NaCl solution; centrifugally degreasing to remove paraprotein; adding water to regulate the pH value of initial slurry to be 8.0-8.5; performing combined gradient enzymolysis on alkali protease and neutral protease; deactivating enzyme after the enzymolysis is ended; performing adsorption bleaching by activated carbon; and then performing rough filtration, fine filtration, evaporation concentration and spray drying to prepare the high-purity fishy smell and foreign odor-free fish collagen protein peptide. The high-purity fishy smell and foreign odor-free fish collagen protein peptide disclosed by the invention has a simple process and is easy to industrial production; fishy smell, foreign odor and non-collagen proteins are fully removed in production; the low-temperature biological enzymolysis technology is adopted, and other substances are not added, thereby, the product quality is improved; an obtained fish collagen protein peptide powder has the characteristics the content of amino acid hydroxyproline is not less than 9 percent, and the average molecular weight is lower than 1000Dal; no fishy smell or foreign odor cannot generated, and obvious fishy smell or foreign odor also cannot be generated through heating treatment under the acid conditions. The high-purity fishy smell and foreign odor-free fish collagen protein peptide can be widely applied to processing of various foods and cosmetics as a green functional ingredient.

The device for debonding and cleaning fish oosperm is characterized in that a debonding agent trough (19) is provided with a water inlet pipe (18); the bottom of the debonding agent trough (19) is provided with a discharging agent pipe (14) and an aerator (15); the bottom of the debonding and cleaning trough (19) is provided with a material discharging pipe (4) and an aeration ring (3); the upper edge of the debonding and cleaning trough (19) is provided with a screen ring (20) and the periphery thereof is provided with an overflow ring trough (22); the bottom of the overflow ring trough (22) is provided with a water inlet pipe (2); the upper opening of the screen ring (20) is provided with a oosperm inlet (21); an oosperm collecting internal trough (7) is provided with an arc-shaped bottom; the upper periphery is provided with a screen (5); an oosperm collecting external trough (6) is a provided with a conical bottom (10), the center of which is connected with a drainage pipe (11); a sieve pore shelf (9) is provided with the aeration ring pipe (8); and the discharging agent pipe (14) of the debonding agent trough (19) is connected with the debonding and cleaning trough (1) at high attitude by a water pump (13), and the lower part thereof is connected with the upper opening of the oosperm collecting trough by the material discharging pipe (4). In the invention, standardization of the debonding and cleaning procedure of the oosperm can be ensured, the automation can be realized, the damage rate of the oosperm can be reduced, the labor intensity can be decreased and the water can be saved.

A fish cleaning device includes a base having an upper surface and a lower surface, one or more arms, each having a first and second end. The first end of the arm is pivotally attached to the base. A clamp-securing member is pivotally attached to the second arm end and a clamp is attached to the clamp-securing member. The device allows for the cleaning of both sides of a fish with decreased handling of the fish. The device is used by securing the fish to the clamp, cleaning one side of the fish, pivoting the arms relative to the base, thereby flipping the fish, and cleaning the second side of the fish.

The invention relates to a preparation method for baking Salmon food on slow fire, which comprises the following steps: selecting fresh Salmons as raw materials; soaking the Salmons in 3-5 percent salt water for 3-5 minutes; taking out, leaching and cutting the Salmons into fish sections; placing the cut fish sections in 3-5 percent salt water to clean for 1-3 minutes; taking out, leaching and putting the cleaned fish sections in sauce for impregnating and favoring for 2-3 hours, wherein the sauce comprises the following components in percentage by weight: 0.5-2 percent of monosodium glutamate, 1-3 percent of salt, 5-10 percent of sugar, 5-10 percent of sorbierite, 40-55 percent of chili sauce and 20-35 percent of water; putting the favored fish sections in an oven, controlling the temperature between 180 and 200 DEG C and baking for 3-5 minutes; and carrying out low-temperature quick cooling treatment on the baked fish sections till the central temperature reaches 0-5 DEG C, and packaging and sterilizing the treated fish sections to obtain finished products. The Salmon food baked on slow fire does not damage mostly of nutrient substances, is soft and tender fresh quality, strong baking favor, proper salt degree and delicious. The preparation method has simple and reasonable process, feasible operation and easy realization of industrial production.

The invention discloses a self-cleaning fish tank which comprises a fish tank body. A cavity is formed in the fish tank body. A water outlet pipe is arranged on the fish tank body. A cavity is formed in the right side wall of the fish tank body and forms a cavity part. A supporting block is arranged on the inner wall of the cavity part. A ball is arranged on the right side wall of the supporting block and connected with a push piece in a rotating mode. The lower end of the push piece extends into the water outlet pipe. A spring is arranged between the right side of the push piece and the inner wall of the cavity part. A gas bag is arranged on the upper side face of the supporting block. The gas bag and the push piece abut against each other. The upper end of the gas bag is connected with a gas inlet pipe. The left side of the gas bag is connected with a gas outlet pipe. A semicircular groove is formed in the gas outlet pipe. A rotating shaft is arranged on the inner wall of the gas outlet pipe and connected with fan blades. The lower end of the rotating shaft is fixedly connected with a circular connection plate. Bristles are arranged on the lower side face of the circular connection plate. Stop rods are arranged in the circumferential direction of the rotating shaft and provided with connection pieces. During water changing, the bottom face inside the fish tank is automatically swept.
