Description

Technical Field

[0001] The utility model relates to the technical field of fermented black beans processing, in particular to a fermented black beans sun-drying device. Background Art

[0002] Douchi is a traditional Chinese fermented bean seasoning. Douchi uses black beans or soybeans as the main raw materials. It uses the action of Mucor, Aspergillus or bacterial proteases to decompose soybean protein. When it reaches a certain level, it is made by adding salt, wine, drying, etc. to inhibit the activity of the enzyme and delay the fermentation process. Douchi has the effects of soothing the stomach, eliminating restlessness, and removing cold, and it is also helpful in reducing blood cholesterol and lowering blood pressure. Douchi is often used as medicine. Due to different processing methods, the effects are also different. The medicinal properties of Douchi made with Artemisia annua and mulberry leaves are cold; the medicinal properties of Douchi made with Patchouli, Perilla frutescens, Perilla frutescens, and Ephedra chinensis are warm; the medicinal properties of Douchi made without other drugs are very weak, and if it is to work, it still needs to rely on Ephedra chinensis and Perilla frutescens.

[0003] Select soybeans with full grains and no pests and diseases, and soak them in clean water. Depending on the season and climate, the soaking time is generally between 10-12 hours. The purpose of this step is to allow the soybeans to fully absorb water and swell, and prepare for subsequent steaming. Put the soaked soybeans into the steamer for steaming. The cooking time and temperature should be adjusted according to the variety and state of the soybeans to ensure that the soybeans are cooked and not rotten. After the steaming is completed, the soybeans are quickly cooled to maintain their original taste and flavor. The cooled soybeans are placed in a fermentation barrel, and appropriate amounts of microorganisms such as Aspergillus and yeast are added. The temperature and humidity are adjusted to allow the soybeans to ferment under suitable conditions. In this process, microorganisms will decompose the protein and sugars in the soybeans to produce the unique aroma and taste of fermented black beans. After the fermentation is completed, the fermented black beans are dried to a certain dryness and humidity and stored for sale. The drying time and degree will also affect the taste and quality of the fermented black beans. The aroma and taste of the fermented black beans that have been properly dried and stored will be more intense and unique.

[0004] After fermentation, the fermented black beans need to be air-dried to increase the storage time of the black beans. However, the air-drying process of industrial black beans is generally carried out by circulating high-temperature air. The circulating air can easily bring external dust and bacteria into the drying room, affecting the production quality of the black beans. The position of the high-temperature air drying vents is fixed, which can easily cause the black beans in the black bean drying tray near the vents to be over-dried, resulting in large deviations in batch production quality.
