Description

Technical Field

[0001] This utility model relates to the field of fresh food preservation equipment technology, and in particular to a soaking device for preserving Yadong salmon fillets. Background Technology

[0002] In the processing of Yadong salmon fillets, preservation is a crucial step determining the product's shelf life and quality. Immersion is widely used due to its ability to evenly coat the fillets with preservatives and its relatively low operating costs. Currently, most fillet immersion devices on the market are static tanks, some equipped with simple stirring mechanisms. In practical applications, static immersion devices often suffer from uneven immersion due to the stacking of fillets, especially in batch processing, where fillets in the central area fail to fully contact the preservative solution, leading to localized preservation failure. Some stirring devices use paddle agitators, but the speed control precision is insufficient, easily causing damage to delicate fillets like Yadong salmon, affecting product appearance. Furthermore, the sealing performance of traditional devices varies, and frequent opening of the tank lid for observation or liquid replenishment can easily introduce external contaminants, disrupting the stable preservation environment inside the tank. The inlet and outlet structures are also relatively simple, often only equipped with basic drain ports, requiring separate equipment for pretreatment, increasing the number of fillet transfers and operational steps, resulting in low overall processing efficiency. In addition, as a specific species, the Yadong salmon has higher requirements for the stability of the preservation environment and the uniformity of soaking than ordinary fish fillets, and existing general-purpose soaking equipment is difficult to fully adapt to its processing needs.

[0003] Currently, there is an urgent need in the market for a soaking device for preserving Ya-Dong salmon fillets. This device has been optimized and upgraded through structural designs such as "rotating drum + lifting plate", "sealing cover + observation window", "spray pipe + drain valve" and stable support of bearing seat, and finally formed a special device suitable for preserving Ya-Dong salmon fillets. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a soaking device for preserving Yadong salmon fillets. This device achieves thorough soaking while minimizing mechanical damage to the fillets. By combining a sealed environment with spray pretreatment, it further ensures the freshness and commercial value of the Yadong salmon fillets. It also allows for the rapid discharge of waste soaking liquid after soaking, simplifying the subsequent cleaning process. The spray pipe and several spray holes on the upper part of the tank's inner wall allow for the pre-rinsing of the fillets with clean water or pretreatment liquid through the inlet valve before soaking, improving overall efficiency.

[0005] This utility model also provides a soaking device for preserving Yadong salmon fillets, including a tank body, a closable sealing cover on the top of the tank body, a roller rotating around a horizontal axis inside the tank body, a motor inside the roller, the motor being electrically connected to the roller, and a drain port at the bottom of the tank body, the drain port being connected to a drain valve.

[0006] According to the present invention, a soaking device for preserving Yadong salmon fillets is provided, wherein the motor is electrically connected to a reducer, the output shaft of the reducer is connected to a coupling, the coupling is fixedly connected to a rotating shaft, and the rotating shaft horizontally passes through the center of both sides of the drum and is fixedly connected thereto.

[0007] According to the present invention, a soaking device for preserving Yadong salmon fillets is provided outside the rotating shaft, and the outer wall of the bearing seat is fixedly supported on the side wall of the tank.

[0008] According to the present invention, a soaking device for preserving Yadong salmon fillets is provided, wherein the sealing cover is fixedly connected to a hinge, the hinge is fixedly connected to the tank body, and an observation window is provided on the sealing cover.

[0009] According to the present invention, a soaking device for preserving Yadong salmon fillets is provided, wherein a spray pipe is fixedly installed on the upper part of the inner wall of the tank, the spray pipe has a plurality of spray holes, and an inlet valve is fixedly connected to the input end of the spray pipe, the inlet valve being located inside the tank.

[0010] According to the present invention, a soaking device for preserving Yadong salmon fillets is provided inside the drum, wherein multiple lifting plates are fixedly arranged inside the drum and distributed around the drum along its outer wall.

[0011] Beneficial effects:

[0012] 1. The drain port at the bottom of the tank, in conjunction with the drain valve, allows for the rapid discharge of waste soaking liquid after soaking, simplifying the subsequent cleaning process. The spray pipe and several spray holes on the upper part of the inner wall of the tank allow for the pre-rinsing of fish fillets by introducing clean water or pretreatment liquid through the inlet valve before soaking, or the addition of preservatives during the soaking process. This achieves an integrated operation of "spray pretreatment - soaking preservation - drain cleaning", reducing the steps of transferring fish fillets and improving the overall processing efficiency.

[0013] 2. The top of the tank is equipped with an openable and closable sealing cap, which can be easily opened and closed via a hinge. When closed, it can form a good sealing environment, reducing the risk of outside air and impurities entering the tank and contaminating the soaking solution and fish fillets. The observation window added to the sealing cap allows staff to observe the soaking status of the fish fillets in the tank in real time without opening the sealing cap. This avoids the problem of frequently opening the cap and damaging the sealing environment, and improves the convenience of operation, meeting the requirements of "less intervention and low pollution" in food processing.
