Problems solved by technology

[0005] 1. The utilization rate of ozone is very low, only about 10%;
[0006] 2. The remaining unused ozone will harm the environment, and further damage treatment is required;
[0007] 3. The concentration of existing ozone water used for harmless treatment is low, and the sterilization and decomposition of pesticide residues are not thorough enough;
[0008] 4. When treating food by soaking and cleaning, since a large amount of pollutants on the surface of the food are dissolved in water, a large part of the ozone originally dissolved in water for food harmless treatment will be consumed by the pollutants in the water, resulting in ozone Low utilization rate and poor efficiency

Embodiment 1

[0047] Embodiment 1 carries out harmless treatment to 50 tons of fresh lychees

[0048] 1) conventional ozone machine (can prepare 1kg O per hour) by gas inlet pipe 11 3 ) prepared containing 10% O 3 and 90% O 2 The mixed gas continues to flow into the mixing tower 12, and at the same time, the purified water treated by secondary reverse osmosis is also continuously introduced into the mixing tower 12 through the pure water inlet pipe 10, and the mixed gas and pure water pass through the built-in molecular sieve in the mixing tower 12 13 processing, generated containing O 3 aqueous solution and containing O 3 , O 2 The mixed gas; among them, containing O 3 O in aqueous solution 3 The concentration is about 20mg / L; the ratio of the mixed gas to pure water is 1L of pure water to 200mg O 3 gas.

[0049] 2) 50 tons of lychees to be processed are stacked near the four walls in the sealed box 1, then the mixed gas and aqueous solution obtained in step 1) are continuously int...

Embodiment 2

[0053] Example 2 Harmless treatment of 50 tons of raw pork

[0054] Process and method are the same as embodiment 1, the difference is:

[0055] The ozone machine used can produce 2kg O per hour 3 ;

[0056] The ratio of mixed gas and pure water prepared by the ozone machine is 1L pure water to 400mg O 3 gas;

[0057] The number of ultraviolet lamps 5 arranged in the sealed box is between 60 and 80;

[0058] Step 3) The number of ultraviolet light lamps used to process the recovered gas is also between 60 and 80.

[0059] During the above-mentioned treatment process, about 2kg O was prepared in total by the conventional ozone machine. 3 ; After gas recovery in the treatment process, through 185nm ultraviolet treatment to obtain about 2kgO 3 ; Recycle about 20 tons of pure water; calculated based on this, to process 50 tons of raw pork, only 80mg O per kilogram is used 3 Harmless treatment has been realized.

Embodiment 3

[0060] Example 3 Harmless treatment of 50 tons of fresh shrimp

[0061] Process and method are the same as embodiment 1, the difference is:

[0062] The ozone machine used can produce 2.5kg O per hour 3 ;

[0063] The ratio of mixed gas and pure water prepared by the ozone machine is 1L of pure water to 500mg O 3 gas;

[0064] The number of ultraviolet lamps 5 arranged in the sealed box is between 80 and 100;

[0065] Step 3) The number of ultraviolet light lamps used to process the recovered gas is also between 80 and 100.

[0066] During the above-mentioned treatment process, about 2.5kg O was prepared in total by the conventional ozone machine 3 ; After gas recovery in the treatment process, about 2.5kg O was obtained after 185nm ultraviolet treatment 3 ; Recycle about 25 tons of pure water; calculated based on this, to process 50 tons of fresh shrimp, only 100mg O is used per kilogram 3 Harmless treatment has been realized.

Abstract

The invention provides a harmless processing method of raw and fresh food. The method comprises the following steps: mixing a mixed gas containing O3 and O2 which is prepared by a conventional ozonizer with purified water, and spraying the obtained mixture on surfaces of the raw and fresh food to be processed in a gas spray form. The mixture is made by adding 200-500mg of the O3 gas to 1L of the purified water. The method has the advantages of high efficiency and low cost in processing the raw and fresh food and the like, and is applicable to industrialized implementation.

Description

technical field [0001] The invention relates to a method for harmless treatment of food, in particular to a method for harmless treatment of fresh food. Background technique [0002] Fresh food, such as raw meat, aquatic products, fruits and vegetables, etc., often has a lot of harmful substances such as bacteria, viruses or organic pesticide residues on the surface. As people pay more and more attention to the issue of food safety, the market has higher and higher requirements for the harmless treatment of fresh food before sale. [0003] The US FDA has long advocated the use of ozone for the harmless treatment of harmful substances left in food, because ozone, as a strong oxidant, can remove a wide range of harmful substances compared with other purification methods, and the removal speed is fast, The effect is good. But so far, the related method of using ozone to harmlessly treat food is still in a state of high cost and low efficiency, and has not been industrialized....
