Problems solved by technology

However, in the process of wheat flour production, when the wheat is treated with ozone gas dry method, the detoxification effect of low-concentration ozone is average, and the emission of ozone gas is a new problem when high-concentration treatment is used; In a high-moisture airtight environment, the accelerated decomposition of ozone water cannot continue to oxidize and detoxify. According to relevant research findings (see attach

Example Embodiment

[0055] Example 1:

[0056] Sample pretreatment: Weigh 2kg of wheat A, and remove impurities and stones in the wheat sample with an experimental grain sieve and destoner.

[0057] Deoxynivalenol in wheat A was treated by the above system and method.

[0058] Conditioning method: According to "NYT 1094.1-2006 Wheat Experimental Milling Part 1: Equipment, Sample Preparation and Conditioning", the moisture content of the wheat sample was adjusted to 16 wt%.

[0059] Wherein, after scab polluted wheat A is cleaned up with a vibrating sieve and a stone remover, the concentration of ozone water produced by the ozone water generating tank is 20mg / L, and the moisture of the wheat A is sprayed with water to moisten the wheat for 24 hours to reach 16wt% moisture. The feed inlet of pulverizer 4 feeds the ozone gas of 60mg / L.

Example Embodiment

[0060] Example 2:

[0061] Sample pretreatment: Weigh 2kg of wheat B, and remove impurities and stones in the wheat sample with an experimental grain sieve and stone remover.

[0062] Deoxynivalenol in wheat B was treated with the system and method described above.

[0063] Conditioning method: According to "NYT 1094.1-2006 Wheat Experimental Milling Part 1: Equipment, Sample Preparation and Conditioning", the moisture content of the wheat sample was adjusted to 16 wt%.

[0064] Among them, after the scab-polluted wheat B was cleaned with a vibrating screen and a stone remover, the concentration of 5mg / L ozone water was produced by the ozone water generation pool, and the moisture of the wheat B was sprayed with water to moisten the wheat for 24 hours to reach 16wt% moisture. 20mg / L of ozone gas is fed into the feed port of the leather mill system of the Le Mill.

[0065] The content of deoxynivalenol in Example 1 and Example 2 is detected, and the results are shown in Table...

Abstract

The invention discloses an ozone treatment system and method for degrading deoxynivalenol in wheat. The system comprises an ozone water generation tank, spraying dampening equipment, a wheat wetting bin, a flour mill, a centrifugal deduster, a centrifugal fan and an ozone generator. According to the ozone treatment system and method for degrading the deoxynivalenol in the wheat, a synergistic effect of wetting the wheat by high-concentration ozone water and conducting ozone gas negative pressure conveying on flour is adopted, a procedure of washing the wheat with the ozone water is eliminated,not only is the DON toxicity effectively eliminated, but also a general wheat dry-method cleaning technology in the present industry is not changed, on one hand, easy conversion of the deoxynivalenolis promoted, and on the other hand, no sewage is discharged according to the method. In a closed internal circulation process of ozone, a water-dissolved ozone concentration detector is installed onthe ozone water generation tank, an ozone gas concentration detector is installed on an break flour mill inlet in which ozone gas is introduced, by monitoring ozone water and ozone gas concentrationsin a production process, the yield and output of the ozone generator can be precisely adjusted, and DON degradation through the ozone is controllable.

Description

technical field [0001] The invention belongs to the technical field of microbial treatment, and more specifically relates to an ozone treatment system and method for degrading deoxynivalenol in wheat. Background technique [0002] Deoxynivalenol (hereinafter referred to as DON) is mainly produced by Fusarium graminearum and Fusarium pink, and Fusarium is the main pathogen of wheat head blight, wheat head blight is also known as Fusarium wilt (FHB), which is a worldwide disease, is one of the most destructive diseases of wheat and other cereals grown in warm and humid regions of the world. The damage is severe. Wheat head blight and wheat stripe rust and powdery mildew have formed The world's three major diseases that damage wheat. [0003] DON has a high degree of stability, is not easily decomposed by heat, and also has a high degree of heat stability and acid stability. DON can interfere with the activity of ribosomal peptidyltransferase in cells, thereby hindering the c...
