Abstract
The invention discloses a production method for purple sweet potato entire powder, and relates to a food production method. The production method comprises the following steps of: cleaning, peeling and slitting fresh purple sweet potatoes; keeping the color; rinsing; cooking; mashing; refilling; drying; and sieving to obtain a finished product, wherein the drying is rotary flash evaporation drying. Compared with the prior art, the production method for purple sweet potato entire powder protected by the invention has the advantages of saving energy on one hand and improving the product quality on the other hand.
Description
Technical field
The present invention relates to a kind of foodstuff production method, the full powder producing method of particularly a kind of purple potato.
Background technology
Purple potato (formal name used at school: Solanum tuberdsm) cry black potato, purple sweet potato again, be meant that potato meat color is the sweet potato of purple.It also is rich in selenium element and anthocyanidin except the nutritional labeling with common sweet potato.Anthocyanidin has prevention and therapeutic action to more than 100 kinds of diseases, is described as the seventh-largest essential nutrients after water, protein, fat, carbohydrate, vitamin, mineral matter.Anthocyanidin is the disease preventing and treating found of present scientific circles, safeguard human health the most directly, the most effective, safest free radical scavenger, its ability of removing free radical is ascorbic 20 times, 50 times of vitamin E.
The full powder of purple potato is a kind of in the purple potato dehydrated products.With new light violet potato is raw material, through cleans, remove the peel, cut into slices, protect look, rinsing, slaking, smash mud, drying and must fine particulate, sheet consider shape to be worth doing or powdery product is referred to as the full powder of purple potato.
In the full powder production technology of purple potato, at present conventional employing be that drying room is dry, the energy that adopts the method to consume on the one hand is higher, causes the fewer full powder quality of purple potato of generation that makes of anthocyanidin content not high on the other hand owing to drying time is long.
Summary of the invention
the object of the present invention is to provide the full powder producing method of a kind of purple potato, and the full powder producing method of this purple potato can be saved energy consumption on the one hand, has more improved product quality on the other hand.
technical scheme of the present invention is: the full powder producing method of a kind of purple potato; Comprise following production stage: light violet potato cleans peeling, slitting, protects look, rinsing, slaking, smashes mud, backfill, drying, sieve, finished product, wherein said drying is a rotary flashing drying.
As preferred, the device that backfill mixes in the said backfill step adopts single shaft hammer bar formula homogenizer to stir
, and speed of agitator is 1300-1500 rev/min.
as preferred, and backfill is than being 1:1 in the said backfill step, and said backfill is than for from smashing the ratio of mud step products material that comes and the material that comes from the step products of sieving.
as preferred, said rotary flashing drying adopts Rotatingandflashstreamingdrier, and the direction of rotation and the hot-air flow of the drier stirring vane of this Rotatingandflashstreamingdrier are opposite.
as preferred, said rotary flashing drying adopts Rotatingandflashstreamingdrier, and the backgauge collar extension diameter of this Rotatingandflashstreamingdrier is 520mm.
as preferred, said rotary flashing drying adopts Rotatingandflashstreamingdrier, 7185 cubic metres of 130-150 degree centigrade of temperature of control during the pressure fan air-supply of this Rotatingandflashstreamingdrier, pressure 7610 handkerchiefs, air quantity/time.
as preferred, said rotary flashing drying adopts Rotatingandflashstreamingdrier, when 16100 cubic metres of 70-90 degree centigrade of temperature of control during the air exhauster exhausting of this Rotatingandflashstreamingdrier, pressure 4600 handkerchiefs, air quantity.
as preferred, said rotary flashing drying adopts Rotatingandflashstreamingdrier, and the rotating speed of the charger of this Rotatingandflashstreamingdrier is 25-30 rev/min.
Compared with prior art, beneficial effect of the present invention is:
1. mashed potatoes can be dried to water content in second at 10-15 be about 8% granule full powder, with the traditional heated air drying savings in comparison 20%-30% left and right sides energy consumption.
The purple potato product anthocyanidin content that produce
is high.
The purple potato product that produce
can be preserved 1 year at normal temperatures, and its mouthfeel after the rehydration, nutritional labeling are near the purple potato of slaking.
Description of drawings
Fig. 1 is a process chart of the present invention;
Fig. 2 is a rotary flash distillation machine overall structure sketch map of the present invention.
The specific embodiment
below will combine accompanying drawing that the present invention is described further.
Embodiment 1
are of Fig. 1, select new light violet potato, through cleaning, removing the peel, cut into slices, protect look, protect look and adopt color stabilizer (0.1% calcium chloride, surplus is the water drying, mass percent for 0.5% citric acid, 0.1% phytic acid).
protect look after rinsing, slaking, smash and get into single shaft hammer bar formula homogenizer behind the mud and stir the backfill mixing arrangement, and the mixer speed of agitator is 1300-1500 rev/min.
It is dry that the material that come out from mixer
gets into Rotatingandflashstreamingdrier; The Rotatingandflashstreamingdrier drying is as shown in Figure 2, and this Rotatingandflashstreamingdrier drying comprises pressure fan 1, heater 2, air distributor 3, mixer 4, charger 5, drier 6, backgauge collar extension 7, cyclone separator 8, discharger 9, sack cleaner 10 and air exhauster 11.The entering portion that the material that comes out from mixer gets into Rotatingandflashstreamingdrier is for being charger 5.Material dry 7-8 in Rotatingandflashstreamingdrier can be dried to water content in second be about 8% granule full powder.
The direction of rotation of the stirring vane 12 on
mixer 4 needs opposite with hot-air flow; Can make material and hot blast adverse current each other like this, can be not that viscous material causes conglomeration (referring to that material is together adhered to one another) because of the dry material of need when expansion drying like this.Backgauge collar extension 7 diameters are 520mm (backgauge collar extension 7 is a kind of clasfficiators), and the full powder moisture Control of discharging of discharging opening that makes drier 6 like this is in 8%.7185 cubic metres of 130-150 degree centigrade of temperature of control during pressure fan 1 air-supply, pressure 7610 handkerchiefs, air quantity/time, so just increased the pressure of blowing, solved that to be directed to purple potato granule full powder this than great, a sticking dry difficult problem.When 16100 cubic metres of control 70-90 degree centigrade of temperature, pressure 4600 handkerchiefs during air exhauster 11 exhausting, air quantity.Charger 5 adds a device for spiral, and the rotating speed of charger 5 is 25-30 rev/min.
The material that come out from discharger 9
is after sieving; A part of one-tenth finished product (sample thief A anthocyanidin content to be detected) entering bin storage after packing; Another partly returns the backfill mixing arrangement, and the inventory of returning can be less than 1 with the ratio of the inventory of coming from smashing the mud step products.
testing result sees the following form.
The comparative example 1
are (about 30 minutes drying times, longer than embodiment 1) except that drying adopts the drying room drying, and all the other technologies are identical with embodiment 1, and the water content of dry products also is about 8% granule full powder, gets finished product sample B anthocyanidin content to be detected.
[0026]
testing result sees the following form.
