Description
Technical field
The invention belongs to food processing technology field, it is related to a kind of killing cereal microorganism and worm's ovum using superheated steam
System and method for.
Background technology
Containing more microorganism and worm's ovum after grain harvest, its product quality is influenced.
We to nearly 20 wheat samples analysis shows, the wheat of different sources and different cultivars, total plate count is equal
1 × 104More than, part even as high as 5 × 104.Meanwhile the worm's ovum in flour is also to influence flour quality and flour-made food product
An important factor for matter.
Since planting environment is more severe, surface microorganism content becomes apparent from higher than wheat buckwheat.Our testing result
Show the total plate count on buckwheat surface mostly more than 1 × 105, part even more than 6 × 105.The wheats class such as oat, barley, chick-pea,
All there are similar situations for the beans such as hyacinth bean.
In order to solve the problems, such as the microorganism in wheat flour and worm's ovum, many enterprises attempted ultraviolet-sterilization, ozone sterilization,
Infrared or irradiation, heating or the methods of peeling (stone roller is cut), but there are wheat albinism line it is impacted the problems such as (cuckoo, low bacterium
Wheat flour production key technology research, Nanjing University of Finance and Economics's Master's thesis, 2010, p5).The technology once promoted is also clear
Method is washed, but since water consumption is big, the contaminated wastewater environment after cleaning causes to be continuing with now substantially free from enterprise.
In order to solve the problems, such as the worm's ovum in wheat flour, most popular is high-speed impact machine.Using high-speed rotating
Rotor impacts killing worm's ovum repeatedly, but equipment energy consumption is higher, hence it is evident that increases cost.
With the development of overheat steam technology, superheated steam is more and more extensive in the application of food processing field, but these
Technology is chiefly used in drying, bake, for sterilize and deinsectization report there is not yet.Canada has scholar's research and utilization overheat to steam
Vapour kills the sickle-like bacteria in wheat, but processing time length, temperature height (since sickle-like bacteria is toxic, need high temperature and long time treatment
Could decompose), treated, and wheat is usually used as production bioenergy, without the concern for influence of the treatment conditions to its gluten.
Meanwhile the conveying-type material mode of movement that existing superheated steam processing system uses, treating capacity is smaller, the degree of automation is low,
Cereal lacks in processing procedure to be stirred, and causes to handle uneven.And this technology is directed to the cereal for food processing, it is right
It needs to be controlled as far as possible in the influence of gluten strength (Dough stability time), starch (gelatinization degree) etc..

The present invention is handled cereal using superheated steam, the content of microorganisms that can be substantially reduced after powder processed, is improved
Whiteness.
First, it is in tilted layout using roller sterilizing chamber 9, makes cereal side quilt using the centrifugal force and cereal dead weight of roller rotation
Throw side to discharge port move, and superheated steam from drawing mechanism 8 spray into roller in, come into full contact with cereal, ensure cereal by
Heat and the uniformity of sterilizing.The gradient that roller sterilizing chamber 9 arranges is bigger, and flowing velocity is faster under the effect of gravity for cereal, paddy
Object residence time in roller sterilizing chamber is shorter.
Meanwhile the rotary speed of roller sterilizing chamber 9 is the rotation speed by 5 variable frequency adjustment pinion gear of variable frequency drive motors
Degree, is fixedly mounted on so as to change in roller sterilizing chamber 9, and the rotary speed reality of installation transmission gear wheel 7 is engaged with pinion gear
Existing, the gradient for the roller sterilizing chamber 9 that cooperation rack changes with inclination-angle regulating device, thus it is possible to vary cereal throws amplitude and paddy
Object flowing velocity.
Thermal insulation layer 4 is wrapped in feed arrangement 2, drawing mechanism 8, roller sterilizing chamber 9 using the rock wool of resistance to 400 DEG C or more high temperature
With the outside of steam circulation pipeline 10, between 0.5~20cm, the heat that can effectively reduce superheated steam dissipates 4 thickness of thermal insulation layer
It loses, heat preservation energy-saving；And the surface temperature of constituent system components is reduced, prevents operating personnel from scalding.
The steam that steam generator 13 generates further is heated by heater 12, reaches the temperature of setting.Heater 12
It is arranged near drawing mechanism 8, thermal loss can be effectively reduced, ensure the temperature of superheated steam, reduce energy consumption.
Meanwhile wind turbine 11 is blasted the superheated steam in heater 12 in roller sterilizing chamber 9 using air blast mode, on the one hand
11 heat intensity of wind turbine is reduced, reduces energy loss, while also shortens the superheated steam after heating to roller sterilizing chamber 9
Fed distance.
The content of either microorganism or worm's ovum, wheat surface and ventral groove is far above inside wheat.Therefore we taste
Examination carried out wheat using superheated steam superhigh temperature (being more than normal pressure saturated-steam temperature) and at the short time (within 3 minutes)
Reason, to realize the purpose for reducing microorganism and egg counts simultaneously.
The experimental results showed that wheat content of microorganisms after treatment significantly reduces.
Influence of 1 superheated steam of the table processing to wheat yeast and mold
Influence of 2 superheated steam of the table processing to total plate count
The processing of 3 superheated steam of table is to the killing effect of bacillus
From the above data, it can be seen that superheated steam processing can kill most of microorganism within a very short time, even if
It is more heat safe bacillus, can also significantly reduces.
We may worry that the superheated steam processing of high temperature can generate unfavorable shadow to the color and luster and farinograph property of wheat flour
It rings.But result of study shows either whiteness or farinograph property, all makes moderate progress.But, it has been found that when the temperature is excessively high,
Processing time is difficult to control, and the problems such as wheat is charred denaturation easily occurs, influences its powder characteristic processed, therefore, when wheat is handled
Superheat steam temperature should be controlled within 180 DEG C.
We also indicate that the handling result of buckwheat, oat, barley, chick-pea and hyacinth bean, by 180 DEG C of superheated steam
120s is handled, bacillus does not detect after processing, and total plate count reduces by hundred times or more (by × 105It is reduced to × 103), and to it
The influence of starch burn degree is controlled within 3%, has identical processing characteristics with the miscellaneous beans of untreated coarse cereals.
It should be noted last that：The above embodiments are only used to illustrate and not limit the technical solutions of the present invention, although ginseng
The present invention is described in detail according to above-described embodiment, it will be understood by those of ordinary skill in the art that：It still can be to this
Invention is modified or replaced equivalently, without departing from the spirit or scope of the invention, or any substitutions,
It is intended to be within the scope of the claims of the invention.
