Abstract

A whitening, sterilizing and disinfecting method for production of wheat flour features that after wheat grains are cleaned, screened and peeled, the aqueous solution of ozone, which is saturated approximately, is used to immerse peeled wheat grains as the strong oxidizing power due to its indefinite domain and big pi bond structure, which has the whitening, sterilizing and disinfecting action.

Description

The new method that brightens, sterilizes, sterilizes in a kind of flour production

The present invention relates to a kind of new method that brightens, sterilizes, sterilizes in flour production.

Cause pink colour band Huang because of the lutein face in the carotenoid that contains trace in the flour.Now, flour factory increases the market competitiveness for improving pink colour, and benzoyl peroxide (BPO) is extensive use of as brightening agent.GB GB2960-86 regulation, the addition of BPO must not surpass 3/10000ths.But because national health department is difficult to control, most of flour factory is merely for the competitive market with increase benefit, overproof use BPO.Though this has bleached flour, cause the residual of multiple harmful substances again, make flour can not eat wheat fragrance, long-term eating can be caused the harm of harmful substance to human body, and increased the cost of flour.

Task of the present invention provides the new method that brightens, sterilizes, sterilizes in a kind of flour production.

Scientific research proves that ozone is one of known strong oxidizer, and its molecular formula is O ₃, three V-shaped arrangements of oxygen atom.The central oxygen atom is taked SP ²Hydridization forms three SP ²Hybridized orbit (having 4 electronics), one of them hybridized orbit is that lone pair electrons are shared, two other unpaired electron respectively with the oxygen atom SP of both sides ²Unpaired electron forms two (SP on the hybridized orbit ²-SP ²) the σ key.The central oxygen atom has neither part nor lot on the P track of hydridization a pair of electronics, the oxygen atom of both sides has neither part nor lot on the p track of hydridization respectively an electronics, these P tracks that have neither part nor lot in hydridization are parallel to each other, overlap each other to have formed the big π key of the three center quadrielectrons perpendicular to planes of molecules.This big π key is the big π key of localization not, and promptly bonding electrons is not fixed between two atoms.The molecular structure of ozone has determined the strong oxidation of ozone.By experiment: when ozone contact flour or during the wheat after grinding skin, have efficient bleaching, sterilization, disinfective action, can effectively kill various bacteria and flour mite worm's ovum in the flour, residual agricultural chemicals in the oxidation Decomposition flour.And ozone finally generates oxygen after contact and acting on flour or grind the wheat of skin, without any the generation of chemical substance, has kept the original taste and the nutrition of flour.

A small-sized flour mill that produces 20,000 kilograms in flour daily if adopt benzoyl peroxide as brightening agent, presses addition 3/10000ths and calculates, and need 6 kilograms every day, and 28 yuan of per kilograms need 168 yuan of RMB.Produce calculating by annual 300 days, then need 50,000 yuan 04 hundred yuan.Adopt 1.5 ten thousand yuan of this phase technology one-time investments, can increase 3.5 ten thousand yuan of profits then.One the daily output 100,000 kilograms can gain 17.5 ten thousand yuan medium-sized flour mill year.Produce the large-scale flour mill more than 200,000 kilograms daily, year can gain more than 350,000 yuan.

The ozone that the present invention carried is easy to preparation:

1. original electrion process.

2. German voltolising method of inventing.

3. ozone lamp afterwards, i.e. the ozone generator of glass tubular type, this be before domestic method commonly used.

4. based on " high-frequency ceramic creeping discharge generate ozone " technology of modern electronic technology.Flaky pottery ozone generator kind is many, and volume is little, and the life-span is long, and the growing amount of ozone is very big.

Be described in further detail below in conjunction with specific implementation method:

Adopt " the high-frequency ceramic creeping discharge generates ozone " technology: the GW3500 type, every ceramic ozone growing amount is 3.5g/h, power is 60w.Wheat adopts dry type to grind the skin method of cleaning: after grinding skin, used nearly saturated Ozone Water wheat wetting two to four hours, can reach the purpose that brightens, sterilizes, sterilizes to flour.

Claims

The structures shape of ozone ozone have strong oxidation.When its contact flour or during the wheat after grinding skin, have efficient bleaching, sterilization, disinfective action, and finally generate oxygen, without any the generation of chemical substance or residual.It is characterized in that ozone is applied in the bleaching of flour, sterilization, the sterilization.
2. ozone according to claim 1 contact has efficient bleaching, sterilization, disinfective action when grinding wheat behind the skin, it is characterized in that wheat adopts the dry type method of cleaning, after grinding skin with the nearly full Ozone Water wheat wetting that closes.
