Description

Technical Field

[0001] The utility model relates to the technical field of black soldier fly processing, in particular to a drying device which can be stacked and fixed. Background Art

[0002] Black soldier flies are a kind of aquatic insects with high nutritional value, and are widely used in feed, food, medicine and other fields. However, the fresh state of black soldier flies is not stable and is easy to rot and deteriorate, so they need to be dried to extend the shelf life and improve product quality. Traditional drying methods usually use hot air drying, but this method is inefficient, time-consuming, and cannot guarantee that the nutrients of black soldier flies are not lost. Therefore, people have invented a drying device that can quickly and efficiently ensure the original nutrients of black soldier flies.

[0003] The black soldier fly drying device usually includes an oven, a drying tray, a drying rack, a heater and a control system. The oven provides a drying space, the drying tray holds the black soldier flies for easy drying, and the heater heats and dries the black soldier flies. The control system controls the power of the heater according to temperature feedback to achieve the best drying effect.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. During the drying operation, the existing black soldier fly drying device needs to place the baking tray on the baking rack inside the oven for drying. Since the spacing between the baking racks is large and they are fixed and cannot be adjusted, the space inside the oven is wasted and the drying output is low; 2. The general black soldier fly drying device uses a heating tube to directly irradiate and heat the baking tray. Since there are a large number of baking trays on the baking rack, the baking trays at different levels are heated unevenly, the black soldier fly drying effect is not good, and there is a semi-dry and semi-wet phenomenon, which affects the product quality.
