A microalgae powder conveying and sterilizing device

Abstract

A microalgae powder conveying and sterilization device, comprising a first agitating mechanism (1) and a first sterilization mechanism (2); the first agitating mechanism (1) comprises an agitating hopper (11), an agitating motor (12), an agitating shaft (13), an agitating screw (14), and an agitating feeding blower (15); the first sterilization mechanism (2) comprises a sterilization column (21), a sterilization feeding blower (26), a sterilization screw friction device and magnetrons (25); the sterilization column (21) is of a cylindrical structure, and the sterilization column (21) is internally provided with a sterilization chamber; a sterilization feeding pipe (212) is provided on the upper end of the sterilization column (21), and a sterilization discharge port (211) is provided on the lower end; the sterilization feeding blower (26) is mounted on the sterilization feeding pipe (212); the sterilization screw friction device is mounted in the central portion of the sterilization chamber; a plurality of magnetrons (25) are mounted on two sides of the sterilization column (21) from top to bottom; and an agitating discharge port (111) and the sterilization feeding pipe (212) are in communication with each other by means of a conveying connection pipe (5). The microalgae powder conveying and sterilization device has good sterilization effect and high sterilization efficiency, microalgae powders obtained therefrom contain no cancerogenic substance, and the nutrition of the microalgae powders is not lost.

Description

technical field [0001] The invention relates to the field of sterilization of microalgae powder, in particular to a microalgae powder delivery and sterilization device. Background technique [0002] There are many kinds of microalgae, and microalgae cells contain high-value nutrients and chemical raw materials such as protein, lipid, algal polysaccharide, β-carotene, and various inorganic elements (such as Cu, Fe, Se, Mn, Zn, etc.) . Microalgae are high in protein and are an important source of single-cell proteins (SCPs). Vitamin A, vitamin E, thiamin, riboflavin, pyridoxine, vitamin B12, vitamin C, biotin, inositol, folic acid, calcium pantothenate and niacin added to its value as an SCP . The content of carotenoids in microalgae is high, which has the function of coloring and nutrition, and can be used to prevent and treat cancer, anti-radiation, delay aging, enhance the body's immunity and other physiological functions. The chemical synthesis is all trans β-carotene,...

AI Technical Summary

Problems solved by technology

At present, the existing microalgae powder is generally sterilized by radiation, but the nutrients inside the microalgae powder will also be lost during the sterilization, which reduces the nutrients of the microalgae powder, and the sterilization effect is poor, low efficiency
