[0002] Selenium is an essential trace element for the human body. Selenium can improve the immune function of the human body, prevent cancer, prevent cardiovascular and cerebrovascular diseases, protect the liver, etc. Therefore, scientific selenium supplementation can prevent hypertension, heart disease, hyperglycemia, etc. The common ways of selenium supplementation are through eating selenium-containing foods and selenium-containing health foods. The latter is a more simple and convenient way. At present, there are various categories of selenium products. Among them, selenium capsules are a common type. During the production of selenium capsules, the raw materials need to be dried. The common drying method is vacuum drying. Compared with ordinary drying methods, the oxygen content is less during vacuum drying, reducing the oxidation of the dried items.
