[0002] Pet food often contains various seafood ingredients, such as salmon, shrimp, mussels, and crab meat, to increase pets' nutrition and palatability. In addition, meat, eggs, animal organs, grains, and other micronutrients are also added. Therefore, in the initial stages of pet food production, all ingredients need to be mixed and stirred. However, current mixing equipment lacks preservation devices, especially for ingredients containing seafood, where the umami flavor is retained for a very short time, easily becoming more fishy than fresh, resulting in a poor taste. Utility Model Content

[0004] This application provides a seafood preservation production device for preparing pet food, including a stirring pot with a circular cross-section. A discharge port is provided on the stirring pot along a tangential direction, and a discharge pipe extending along the tangential direction is fixedly connected to the discharge port. A discharge gate is rotatably connected to the discharge port. A rotating shaft is rotatably connected inside the stirring pot, and a stirring blade is fixedly connected to the rotating shaft. The pushing direction of the stirring blade is the same as the tangential direction of the discharge port. A lid is fixedly connected to the top of the stirring pot, and an air cylinder is fixedly connected to the center of the lid. The top of the air cylinder is located above the lid, and a modified atmosphere device is connected to the air cylinder. The lower part of the air cylinder passes through the lid and is located inside the stirring pot, with the bottom of the air cylinder open. The rotating shaft extends upward through the air cylinder, and a motor is connected to the top of the rotating shaft via a belt drive.

[0005] Furthermore, the rotating shaft is rotatably connected to the top of the air cylinder, and a driven pulley is fixed at the top of the rotating shaft. The motor is fixed on the outer surface of the mixing pot, and a driving pulley is fixed on the output shaft of the motor. A transmission belt connects the driving pulley and the driven pulley.

[0006] Furthermore, an air inlet is eccentrically located at the top of the air cylinder, and an air pipe is connected to the air inlet, which in turn connects to an atmosphere regulating device.

[0007] Furthermore, multiple air holes are provided on the side of the mixing pot.

[0008] Furthermore, an eccentric feeding gate is installed on the pot lid, and the feeding gate is hinged to the pot lid.

[0009] Furthermore, the lid is made of a transparent material.

[0010] Furthermore, a refrigeration device is installed at the bottom of the mixing pot.

[0011] The beneficial effects of this utility model are: This utility model combines modified atmosphere technology and low temperature preservation technology in the stirring device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 The illustrated seafood preservation production apparatus for preparing pet food includes a mixing pot 1, the inner wall of which is made of food-grade stainless steel. Figure 2 As shown, the mixing pot 1 has a circular cross-section. A discharge port is provided on the mixing pot 1 along the tangential direction. A discharge pipe 2 extending along the tangential direction is fixedly connected to the discharge port. A discharge gate 3 is rotatably connected to the discharge port. A rotating shaft 4 is rotatably connected inside the mixing pot 1, and a stirring blade 5 is fixedly connected to the rotating shaft 4. The stirring blade 5 stirs the ingredients inside the mixing pot 1 by rotating. The pushing direction of the stirring blade 5 is the same as the tangential direction of the discharge port. Therefore, during discharge, the rotating stirring blade 5 pushes the ingredients tangentially into the discharge pipe 2. The discharge gate 3 is rotatably connected to the side wall of the mixing pot 1 via a shaft. A micro motor is connected to the shaft, and the micro motor controls the opening and closing of the discharge gate 3. Figure 2As shown, the shaft is located at the discharge port. The discharge gate 3 is rotated counterclockwise until it is attached to the discharge pipe 2. At this time, it is in the open state, and the ingredients in the mixing pot 1 can enter the discharge pipe 2.

[0019] like Figure 1 As shown, a lid 6 is fixedly connected to the top of the mixing pot 1, and an air cylinder 7 is fixedly connected to the center of the lid 6. The top of the air cylinder 7 is located above the lid 6, and an air inlet 8 is eccentrically opened on the top of the air cylinder 7. Figure 3 As shown, an air inlet 8 is connected to an air pipe, which in turn connects to a modified atmosphere device 9. The lower part of the air cylinder 7 passes through the pot lid 6 and is located inside the mixing pot 1, with the bottom of the air cylinder 7 open. The modified atmosphere device 9 prepares a suitable mixture of nitrogen, oxygen, carbon dioxide, ethylene, and other gases. This mixture is released into the mixing pot 1 through the air cylinder 7, thereby preserving the seafood inside. Preferably, the modified atmosphere device 9 is a mixing valve connected to multiple gas generators; the various gases are mixed in the mixing valve and then introduced into the air cylinder 7. Preferably, detectors for multiple gases can be installed inside the mixing pot 1, and the gas volume or flow rate of each gas generator can be adjusted based on the detector results.

[0020] The rotating shaft 4 extends upward through the air cylinder 7 and is rotatably connected to the air cylinder 7 at the top. A driven pulley 10 is fixed at the top of the rotating shaft 4. The motor 11 is fixed on the outer surface of the mixing pot 1. A driving pulley 12 is fixed on the output shaft of the motor 11. A transmission belt 13 is connected between the driving pulley 12 and the driven pulley 10, thereby driving the rotation of the stirring blade 5 through the motor 11.

[0021] Multiple air holes 14 are provided on the side of the mixing pot 1. Excess gas can escape to the outside of the pot through the air holes 14 on the side of the mixing pot 1, thus ensuring the air pressure inside the mixing pot 1.

[0022] like Figure 3 As shown, an eccentrically mounted feed door 15 is installed on the pot lid 6, and the feed door 15 is hinged to the pot lid 6 by a hinge or other device. Lifting the feed door 15 upwards exposes the interior of the mixing pot 1, allowing food ingredients to be poured into the mixing pot 1.

[0023] Preferably, the lid 6 is made of transparent material, so that the food in the mixing pot 1 can be observed at any time to see if it is mixed evenly.

[0024] A refrigeration unit 16 is installed at the bottom of the mixing pot 1, along with a digitally displayed sensor to monitor the temperature inside the mixing pot 1. The refrigeration unit 16 is used to cool the food materials inside the mixing pot 1, keeping them in a slightly cool state to prevent spoilage and prolong freshness. The refrigeration unit 16 can be a vapor compression refrigeration device, a semiconductor refrigeration device, or an absorption refrigeration device, etc.
