Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically a rapid drying device for processing soybean products. Background Technology
[0002] As an innovative form of soy product, tofu balls play a diverse role in daily life, satisfying dietary needs while also possessing cultural and economic value. However, uneven drying of tofu balls can lead to several problems: uneven drying can cause some balls to be too dry (hard and cracked) or too wet (soft and sticky), affecting the overall consistency of taste. Excessive drying on the outside may form a hard shell, while residual moisture inside can cause the center to become sticky. Areas with high moisture content are prone to the growth of mold or bacteria (such as Aspergillus and Staphylococcus aureus), shortening the shelf life and even causing food safety issues. If the tofu balls contain oil, uneven drying may cause areas with low water activity to accelerate fat oxidation, resulting in a rancid taste. Therefore, proper drying of tofu balls is particularly important.
[0003] Currently, there is a lack of a device on the market that can achieve uniform heating of tofu balls and support multiple drying methods. Traditional drying equipment often relies on a single heat source (such as hot air or electric heating tubes), resulting in uneven heating of the balls, causing problems such as dry outside and wet inside or local scorching, which affects production efficiency and product quality. Utility Model Content

[0023] Please see Figure 1-5 This utility model provides a technical solution for a rapid drying device for processing soybean products: It includes a support block 1, and a baking assembly 2. An air blowing assembly 3 is fixedly connected to the outer wall of the baking assembly 2, and a rotating motor 4 is fixedly connected to the outer wall of the baking assembly 2. The baking assembly 2 includes an outer casing 22, with a feed inlet 21 fixedly connected to the top of the outer casing 22, a discharge outlet 23 fixedly connected to the bottom of the outer casing 22, a spiral blade 25 rotatably connected to the inner wall of the outer casing 22, an inner casing 24 fixedly connected to the inner wall of the outer casing 22, and a heating wire 26 fixedly connected to the inner wall of the outer casing 22.
