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 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 does not solve the problem fundamentally. 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 A 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 casing 10 is used as an inlet for food oil, and the other end is used as an outlet for food oil. Each quartz glass lamp tube 12 is equipped with a single-wavelength ultraviolet light source 120. 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 an airtight interlayer 14, the food oil flows in the airtight interlayer 14, and the single-wavelength ultraviolet light source 120 irradiates the food oil in the interlayer 14 by ultraviolet irradiation, so that the food oil The aflatoxin in 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 (Aflatoxin, AFT) in food oil. Background technique [0002] Among the many mycotoxins, aflatoxins are considered to be a strong carcinogenic mutagen with the most prominent potential hazards to humans. They are produced by the secondary metabolism of some Aspergillus flavus and Aspergillus parasiticus, and are a family of dihydrofuran anaphthalene derivatives with similar structures. Common AFTs have several structures such as B1, B2, G1, G2, M1, and M2. Since B1 is the most toxic, AFT is usually referred to as B1. This type of toxin has very good thermal stability due to its macrocyclic conjugated system, and its decomposition temperature is as high as 280°C. [0003] Peanuts, corn and other crops are easily infected with AFT during planting, harvesting and storage, and enter the edible oil during oil extraction, posing a th...
