Problems solved by technology

[0007] Because most of the electric energy is converted into heat energy and ultraviolet rays that cannot decompose AFT, not only the energy utilization rate is low, but also the ozone generated by high temperature, ultraviolet rays and short-wave ultraviolet irradiation also damages the oil and affects the oil while removing AFT in edible oil. Improves the flavor and quality of the oil
In order to solve the problem of large heat generation of high-pressure ultraviolet mercury lamps, equipment with a large processing capacity-"HC20 type aflatoxin elimination machine" of Yantai Dongchang Machinery Manufacturing Co., Ltd. and "aflatoxin removal machine" of Shandong Luhua Group "The devices" are all equipped with cooling equipment, but this cannot fundamentally solve the problem. Problems such as low energy utilization, excessive local temperature of the lamp tube, and ozone generated by short-wave ultraviolet radiation still exist.

[0058] figure 1 The first embodiment of the device for removing aflatoxin of the present invention is shown. See figure 1 , The device includes a food-grade stainless steel cylindrical shell 10 and six quartz glass lamp tubes 12 installed inside the shell. One end of the cylindrical shell 10 serves as an inlet for food oil, and the other end serves as an outlet for food oil. Each quartz glass lamp tube 12 is equipped with a single-wavelength ultraviolet light source 120, and the wavelength of the single-wavelength ultraviolet light source 120 can be any value between 355nm and 375nm, preferably 365nm. Between the cylindrical shell 10 and the quartz glass lamp tube 12 is a closed interlayer 14. Food oil flows in the closed interlayer 14. The single-wavelength ultraviolet light source 120 irradiates the food oil in the interlayer 14 by the ultraviolet irradiation method to make the food oil The aflatoxin in it is decomposed.

Abstract

The invention discloses a method, a device and a system for removing aflatoxin, which is used for improving energy utilization ratio of ultraviolet rays to remove AFT, reducing the influence on edible oil flavor and quality in removing process. The technical scheme of the invention is as follows: the ultraviolet light source of a single wavelength is utilized in the method, grease is irradiated by an ultraviolet ray irradiation method to decompose the aflatoxin in the grease; and the wavelength range of the ultraviolet light source of the single wavelength is 355nm-375nm. The invention is applied to food oil processing.

Description

Technical field [0001] The invention relates to a food oil processing technology, in particular to a method, device and system for removing aflatoxin (AFT) in food oil. Background technique [0002] Among the many mycotoxins, aflatoxins are considered to be a class of strong carcinogenic mutagens that have the potential to be extremely harmful to humans. They are produced by the secondary metabolism of some Aspergillusflavus and Aspergillus parasiticus, and are a family of dihydrofuranophthalene derivatives with similar structures. Common AFT has several structures such as B1, B2, G1, G2, M1, M2, etc. Since B1 is the most toxic, the commonly referred to as AFT refers to B1. This toxin contains a macrocyclic conjugated system and has very good thermal stability, with a decomposition temperature of up to 280°C. [0003] Peanuts, corn and other crops are easily infected with AFT during the process of planting, harvesting and storage, and enter the edible oil during oil extraction, p...
