The effect of anti-mould and anti-moth is played in reason, wheat wetting processing, the setting of UV treatment and packaging bag damp-proof layer.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
A kind of anti-mould and anti-moth storage method of flour, including following operating procedure:
(1) ozone treatment: wheat is transferred in closed container, and ozone gas is passed through into closed container, maintains container
In ozone concentration it is constant, after treatment recycles ozone to container vacuum-pumping, then wheat is produced；
(2) wheat wetting: wheat wetting processing is carried out to the wheat after treated by ozone, wheat wetting is controlled with sodium chloride is dissolved in clear water
Wheat water content is in 14-18%；
(3) it is milled: being milled, including 5 shellings, 5 reductions, 2 sizing, 2 tail rolls, 5 clear powder, obtain to wheat
To the flour of granularity 80-140 mesh；
(4) low temperature drying: made flour is added in roller drier, and low temperature dewatering is to flour at Yu Wendu 50-60 DEG C
Water content is down to 10% or less；
(5) dispense: flour progress pocket type is filling, and packaging bag is worked out using polythene material, is sealed after filling；
(6) it stores: setting the temperature of storage room in 15-25 DEG C, relative humidity in 60-70%, flour is placed in storage room
In, the shelf life up to 12 months.
The ozone concentration is in 50-100mg/L.
The ozone temperature is at 25-35 DEG C.
The ozone treatment time is in 8-12h.
The content of sodium chloride is in 0.5-1.5wt% in the clear water.
In order to further increase the storage quality of flour, the present invention is also mounted with quartz burner in storage room, specifically
Technical solution is as follows:
A kind of anti-mould and anti-moth storage method of flour, including following operating procedure:
(1) ozone treatment: wheat is transferred in closed container, and ozone gas is passed through into closed container, maintains container
In ozone concentration it is constant, after treatment recycles ozone to container vacuum-pumping, then wheat is produced；
(2) wheat wetting: wheat wetting processing is carried out to the wheat after treated by ozone, wheat wetting is controlled with sodium chloride is dissolved in clear water
Wheat water content is in 14-18%；
(3) it is milled: being milled, including 5 shellings, 5 reductions, 2 sizing, 2 tail rolls, 5 clear powder, obtain to wheat
To the flour of granularity 80-140 mesh；
(4) low temperature drying: made flour is added in roller drier, and low temperature dewatering is to flour at Yu Wendu 50-60 DEG C
Water content is down to 10% or less；
(5) dispense: flour progress pocket type is filling, and packaging bag is worked out using polythene material, is sealed after filling；
(6) it stores: setting the temperature of storage room in 15-25 DEG C, relative humidity in 60-70%, and in storage indoor location
Quartz burner, installation number are 2-4/100m2, every the quartz burner of unlatching in 7-10 days, the opening time is in 8-
Flour is placed in storage room by 12h, and the shelf life up to 12 months.
The wavelength of the quartz burner is in 240-280nm, and power is in 80-120W.
Damp-proof layer is equipped with outside the packaging bag.
The damp-proof layer by aqueous epoxy resin emulsion AB-EP-20, curing agent H228B and moisture-proof filler mix after through spraying
It applies, damp-proof layer thickness is at 60-80 μm.
The mass ratio of the aqueous epoxy resin emulsion AB-EP-20, curing agent H228B and moisture-proof filler is 15:1:3.
The moisture-proof filler is modified by coating by mesopore molecular sieve to be made, preparation method are as follows: by mesopore molecular sieve in
100-110 DEG C roasts in 450-500 DEG C after drying to constant weight, after naturally cool to polyanion fiber is added after 125-135 DEG C
Element and isopropyl palmitate, and the insulated and stirred at 125-135 DEG C, then -5 DEG C or less are down to the cooling rate of 5-10 DEG C/min
Heat preservation is stood, and particle most is made through broken afterwards.
The mesopore molecular sieve, polyanion cellulose, isopropyl palmitate mass ratio be 10:0.5-5:0.5-5.
The beneficial effects of the present invention are:
(1) present invention efficiently kills the germ carried in wheat and worm's ovum by ozone treatment, is not influencing wheat food
Germ and the worm's ovum is avoided to destroy wheat under conditions of safety；Ozone is recycled simultaneously, prevents ozone leakage from causing
Problem of environmental pollution.
(2) present invention effectively kills the germ carried in clear water and worm's ovum by the addition of sodium chloride when wheat wetting, and
The actuating quantity of sodium chloride can not only be improved to substitute salt with sodium chloride, but also is avoided that its in salt in addition to sodium chloride
He adversely affects wheat component.
(3) present invention reduces the water content of wheat by low temperature drying, and high temperature drying is on the one hand avoided to influence wheat quality,
On the other hand wheat mould growth due to the moisture absorption is avoided by controlling water content.
(4) present invention guarantees the storage quality of flour by controlling temperature and the relative humidity of storage room, and passes through storage
The control in time limit is deposited to guarantee the edible quality of flour.
(5) present invention prevents during storage mould and insect pest to flour by the installation of quartz burner in storage room
It invades and harasses, and UV treatment is highly-safe.
(6) design of the invention by damp-proof layer increases face to prevent the moisture in external environment from entering inside packaging bag
The water content of powder, which is bred in turn for mould, provides condition, and the damp-proof layer itself has certain moisture absorption ability, and to moisture
Good barrier property；In the preparation of moisture-proof filler, mesopore molecular sieve is wrapped using polyanion cellulose and isopropyl palmitate
It covers, the moisture pick-up properties that polyanion cellulose itself has absorbs partial moisture, and when water absorption reaches maximum, moisture penetrates into
Inside mesopore molecular sieve, continued to absorb moisture by mesopore molecular sieve, to play better dampproof effect to flour.
