Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying equipment, in particular to an abalone processing and drying device. Background Art
[0002] Abalone, a prized seafood delicacy, is beloved by consumers for its tender texture, high nutritional value, and delicious flavor. Dried abalone is typically processed into dried abalone, a naturally fermented meat product. During processing, large protein and fat molecules are enzymatically broken down into small peptides and fatty acids, creating its unique flavor. This process is also significantly affected by the uncertainties of weather.
[0003] Traditional drying methods include natural air drying and hot air drying. Natural air drying is significantly affected by weather, is labor-intensive, and requires extensive experience. Drying abalone requires a low temperature and low humidity environment, which takes a long time and makes it susceptible to mosquito bites and flies. Rainy days can also cause the product to mold and deteriorate.
[0004] Existing abalone hot air drying devices have slow drying speeds and are easily affected by ambient temperature during the drying process. Furthermore, hot air drying alone typically requires high temperatures, takes a long time, and is prone to surface hardening and cracking. During this hot air drying process, the dried abalone remains in contact with oxygen for a long time, leading to fat oxidation and Maillard reactions, resulting in a loss of active ingredients and a poorer taste quality than natural drying. Utility Model Content
[0005] In order to solve the problems in the background technology that the existing natural air-drying method of abalone is time-consuming, greatly affected by weather, and difficult to control the quality, and the taste and quality of dried abalone by hot air drying is inferior to that of natural air-drying, the utility model proposes an abalone processing and drying device.

The smoke extraction pipe is a tubular structure that is transparent from top to bottom. The smoke extraction pipe is located to the right of the left and right holding trays. A funnel pipe is detachably connected to the top of the connecting pipe. The funnel pipe is a funnel-shaped structure that is larger at the top and smaller at the bottom. An exhaust fan is provided on the top of the funnel pipe.
[0010] The bottom of the top plate of the drying box is fixed with an infrared lamp tube and an ultraviolet lamp tube;

[0031] In order to allow the hot air to pass through the holding tray 9 and directly blow hot air to heat the abalone subsequently placed on the holding tray 9 in an all-round manner, the plate body of the holding tray 9 in this embodiment adopts a breathable structure made of steel wire mesh, and this breathable structure also facilitates the heated abalone oil to drip downward to the bottom of the drying box 1 to avoid accumulation in the holding tray 9.
[0032] A hot air generating device 10 is fixedly provided on the top of the drying box 1. The hot air generating device includes a shell and a fan and a heating coil installed in the shell. The fan in this embodiment is a variable speed fan with adjustable speed, and the heating power of the heating coil is adjustable.

The lower end of the air supply duct 11 extends into the drying oven 1 and is located to the left of the leftmost receiving tray 9. The right side wall of the air supply duct 11 is provided with a plurality of exhaust ports 12 spaced vertically within the drying oven 1. The lower end of the air supply duct 11 is sealed. To prevent oil-laden air from backflowing into the air supply duct 11 during shutdown, thereby affecting its air supply efficiency, a one-way air valve is provided at the exhaust port 12 in this embodiment.
