To produce bean sprouts (commonly known as "sprouted bean sprouts"), the following conditions should be considered: ① The formation of bean sprouts, that is, the whole process of sprouting bean sprouts requires completely dark environmental conditions, which are generally guaranteed by the containers of sprouted bean sprouts, but the places where the containers are placed should not be exposed to direct sunlight. ② The growth of bean sprouts needs a warm and humid environment, so the production site should have the ability to regulate and control the appropriate temperature and humidity, and at the same time, the airflow should be stable and convenient for ventilation. (3) In the process of sprouting bean sprouts, in order to radiate the breathing heat of bean sprouts and provide the water needed for growth, it is necessary to spray water for many times, which requires a large amount of water. Therefore, the production site must have clean and sufficient water sources and corresponding drainage capacity. (4) Because the growth cycle of bean sprouts is short, it is often repeated all year round. If it is poorly managed, it will easily lead to diseases such as rotten seeds and buds. In order to reduce diseases, the production site and its facilities must be conducive to cleaning and disinfection to prevent the breeding of miscellaneous bacteria and pests.
According to the above requirements, idle houses are generally used in production and appropriately transformed, but there are also a few "bean sprout houses" specially built according to the requirements. When determining the production area, we must pay attention to the matching with the production volume-the size and quantity of germination containers. For example, to produce 2 barrels of bean sprouts every day, there must be a place to put 14 barrels of germination containers and1~ 2 vats or plastic tubes for storing water and rinsing products.
