Description

Technical Field

[0001] The utility model belongs to the technical field of aquatic product processing; in particular to a hot air drying device for shrimp aquatic products. Background Art

[0002] Since seawater shrimps are not easy to survive and preserve after being caught, most of them are processed by rapid freezing preservation technology or drying and baking technology after being caught. Currently, the most common one is natural drying, which includes two methods: sunlight drying and air drying. Sunlight drying uses the heat energy generated by sunlight irradiation to evaporate the water contained in the product. At the same time, combined with the wind factor, the water vapor discharged from the aquatic product disappears into the air to achieve the drying effect of the aquatic product; air drying is to use the wind provided by nature to continuously blow over the surface of the aquatic product, taking away the water evaporated from the aquatic product to achieve the purpose of drying the aquatic product. This drying method is the most widely used drying method by people so far because of its almost zero cost. However, this method depends on natural climate conditions, has a low control level of drying conditions, cannot guarantee the expected effect of the product, and the product indicators change greatly after drying. Especially when the intensity of sunlight and air humidity cannot be controlled, the drying effect is extremely low. It not only cannot ensure the completion of drying on time, but also causes uneven drying effect or even deterioration of the product. In addition, the sanitary conditions of the product are also difficult to guarantee.

[0003] In addition, a hot air dryer is usually used for drying and baking seawater shrimps. Most hot air dryers use steam or electricity as heat sources, heat through a heat exchanger, the air is forced to circulate by a fan, and the hot air layer flows through the material to be dried to transfer heat and take away the moisture volatilized from the material, so as to realize the drying and baking of the material. This drying and baking method has a high cost, a limited drying area, a good drying effect near the drying area, and a poor drying effect and a high cost far from the drying area. Therefore, a new drying device is needed. Summary of the Invention
