Description

Technical Field

[0001] The utility model relates to the technical field of dried shrimp processing, in particular to a device for dehydrating and color-preserving dried shrimp. Background Art

[0002] Shrimp skin is a dried product of hair shrimp, which comes in two types: raw dried product and cooked dried product. At present, shrimp skin is mainly made from live shrimp through drying and other processes. In the processing of shrimp skin, drying and dehydration equipment is needed to dry the shrimp skin.

[0003] The utility model patent with authorization announcement number CN214903508U discloses a shrimp dehydration device, which includes a dehydration box, a working chamber and a dryer. A rotating mechanism is installed inside the dehydration box, and the rotating mechanism includes a rotating rod, a motor and a bracket. The rotating rod is installed at the middle position inside the dehydration box, and brackets are fixed on both sides of the rotating rod. A motor is installed at the bottom end of the working chamber, and a containing structure is provided inside the dehydration box. A condensation mechanism is installed on one side of the dehydration box, and a sealing door is movably hinged at one end of the dehydration box. The top of the dehydration box is provided with a working chamber; by providing a rotating mechanism, when drying, the motor is started, and the output shaft of the motor drives the rotating rod to rotate at a low speed, which in turn causes the rotating rod to drive the bracket to rotate, and the bracket causes the grid to rotate, so that the hair shrimp inside the grid can be evenly dried and dehydrated, thereby improving the dehydration efficiency.

[0004] Although the shrimp peel dehydration device improves the dehydration efficiency, the device still has the following problems when in use: when the device is drying the shrimp peel, the hot air moves from top to bottom, and in this process, the hot air will pass through multiple holding structures in sequence. Therefore, as the hot air continues to move downward, not only the heat of the hot air gradually decreases, but the wind force will also become smaller and smaller. This situation will cause the shrimp peel in the upper holding structure to bear more heat, while the shrimp peel in the lower holding structure will bear less heat, which will lead to uneven drying. It not only affects the dehydration quality of the shrimp peel, but also easily causes the shrimp peel in the lower layer to oxidize and discolor. In view of this, we propose an integrated dehydration and color preservation device for shrimp peel. Utility Model Content
