[0002] Aquatic products are a general term for animals and plants produced by marine and freshwater fisheries and their processed products. At present, the main aquatic products consumed in my country are fresh and frozen aquatic products. However, with the diversified development of the aquatic product consumption market, the demand for products such as cooked and dried products has shown a rapid development trend. In order to increase the storage time of aquatic products and facilitate processing and transportation, aquatic products are often washed and air-dried.

[0003] Chinese patent (CN215013177U) proposes an efficient air-drying and hanging device for aquatic products, including an air-drying box body, which is a box with a hollow left side, and pads are fixedly installed at the four corners of the bottom of the air-drying box body. A guiding device is arranged on the right side inside the air-drying box body, and the guiding device includes a blow hood, which is in a C-shape, and short connecting rods are fixedly installed on the upper and lower sides of the blow hood. The utility model places the aquatic product between the first plywood and the second plywood by setting a second plywood for pulling. The second plywood is deformed by a stretching spring to pull the second plywood, and the aquatic product generates a rebound force through the stretching spring so that the aquatic product is clamped and fixed under the clamping force of the first plywood and the second plywood.

[0004] The above scheme uses heating and drying as the main air-drying method. This method heats and dries the aquatic products for a long time, which will cause part of the aquatic products to be dried to a half-cooked state, affecting the quality of the product. The energy consumed by the long-term drying method is also relatively large. Utility Model Content

[0026] The utility model is further described below in conjunction with embodiments.

[0027] like Figure 1 - Figure 6 As shown, the utility model proposes an efficient air-drying and hanging device for aquatic products, comprising a support frame 3, an air-drying outer cylinder 1 installed on the support frame 3, an air-drying inner cylinder 2 rotatably installed in the air-drying outer cylinder 1, an air supply mechanism for providing hot air to the air-drying inner cylinder 2, a driving mechanism for driving the air-drying inner cylinder 2 to rotate, and a drainage mechanism for discharging accumulated water, and a hanging mechanism for hanging aquatic products is provided in the air-drying inner cylinder 2.

[0030] A number of evenly distributed air inlet pipes 404 are connected to the surrounding side of the air duct 401, the air inlet pipes 404 pass through the side wall of the air-drying outer cylinder 1 and are sealed to the air-drying outer cylinder 1, the air inlet pipes 404 are connected to the same heating box 405, the heating box 405 is connected to a positive pressure fan, and a number of evenly distributed air inlet holes 406 are opened at the bottom of the air-drying inner cylinder 2 within the range of the air duct 401.

[0031] A plurality of heating tubes 4051 are evenly arranged in the heater box 405 , and electric heating wires are installed in the heating tubes 4051 for heating the air passing through the heater box 405 .

[0032] The drainage mechanism includes leakage grooves 501 distributed circumferentially on the bottom edge of the air-drying inner cylinder 2, water holes 502 distributed circumferentially on the bottom of the air cylinder 401, and a water outlet pipe 503 arranged in the middle of the bottom of the air-drying outer cylinder 1. Water dripping from the air-drying inner cylinder 2 flows into the air-drying outer cylinder 1 through the leakage grooves 501, then flows to the bottom of the air-drying outer cylinder 1 through the water holes 502, and flows out through the water outlet pipe 503.

[0033] The driving mechanism includes two side bearings 601 arranged on the upper and lower sides between the air-drying outer cylinder 1 and the air-drying inner cylinder 2, which are used to support and stabilize the air-drying inner cylinder 2. A gear ring 602 is fixed in the middle of the air-drying inner cylinder 2, and a gear groove 603 is opened on one side of the middle of the air-drying outer cylinder 1. The gear groove 603 penetrates the cylinder wall of the air-drying outer cylinder 1. Mounting seats 606 are fixed on both sides of the gear groove 603.

[0034] The hanging mechanism includes a hanging frame 701 and a limit assembly for limiting the rotation of the hanging frame 701 relative to the air-drying inner drum 2. The hanging frame 701 is provided with a plurality of hanging platforms 702, and a plurality of evenly distributed hanging barrels 703 are fixed on each hanging platform 702.
