Abstract
The invention relates to storage of radishes, in particular to freeze drying of the radishes. The purpose is that part of moisture in cytoplasm, especially in vacuoles, is removed through a method with lower energy consumption, water between cellulose molecules are maintained, then freezing and sublimating are carried out, radish powder is prepared, and the flavor and rehydration capacity of the radishes can be maintained.
Description
The present invention relates to the preservation of radish, particularly relate to the freeze drying of radish, belong to the energy-saving preparation method of a kind of radish freeze-dried powder.In the radish freeze-drying process, the freezing of radish is that whole strain is freezed, the freezing of whole cell.The radish converted products has many kinds, and the freeze-drying radish is one of them important classification.Freeze-drying radish product form comprises bulk, sheet, powdery, granular.The processing of present freeze-dried powder radish is that the radish raw material is carried out pretreatment, quick-frozen, and in the radish cell, moisture forms ice, will ice distillation, and cell dehydration forms the freeze-drying radish, then the pulverizing of freeze-drying radish is obtained the freeze-dried powder radish.The maximum characteristics of various freeze-drying radish have rehydration preferably exactly.This be because the freeze-drying radish in process, the moisture of radish is removed in the mode of ice distillation, thereby has guaranteed that in radish tissue fibers molecule, moisture is overflowed, but the gap also exists.The reconstitution process of freeze-drying radish is namely that moisture reenters radish tissue fibers molecular gap.
Patent of the present invention is completed like this: 1, select fresh radish to clean, process.2, killing cyanines processes.3, will kill that the radish that cyanines processed is pulverized, making beating, fine grinding, the radish fine grinding requires fineness between the 600----900 order.4, the radish slurry is placed in inspissator and carries out Vacuum Concentration: radish slurry thickening temperature requires to carry out reduced pressure concentration between 50----65 degree centigrade; The drier that radish slurry method for concentration adopts band to stir; In concentrated radish slurry, require solid contents at 35----65%.5, will through concentrated radish underflow sabot, carry out fast frozen.6, the radish underflow of having freezed enters vacuum chamber, first carries out preheating, makes it near boiling point, then vacuumizes and make the ice distillation.7, it is block that the material of having sloughed moisture is, and meets the requirements of fineness through pulverizing, is the manufactured goods of powder radish.
Embodiment 1:
1. take radish some, through arranging, cleaning, use chlorine dioxide antiseptic, obtain clean radish..
2. kill cyanines with boiling water.Killing the cyanines method is that radish is dropped into the container that fills boiling water, after radish is dropped into, controls 96----98 degree centigrade of water temperature, keeps 60----75 second, takes out radish and drops at once in cooling water, makes it be down to normal temperature, takes out, and drains the moisture on surface.
3. radish is pulverized.Be that coarse crushing and fine powder are broken in two steps.Fineness is between 750--900.Coarse crushing is first cut, is pulverized with shearing crusher, obtains containing the radish slurry of coarse fiber bundle.
Fine powder is broken, above-mentioned radish slurry is carried out fine powder with micronizer more broken, obtains the fineness that needs.
4. the radish slurry is concentrated.Radish slurry after pulverizing, its solid contents is 5.5% left and right, it is concentrated, and thickening temperature 55-60 degree centigrade, reduced pressure concentration makes its solid contents reach 35-45%.5. freeze.To concentrate radish Juice and carry out sharp freezing, and the centering solidification point to be not more than-12 degrees centigrade.
6. ice distillation.Vacuum freeze drying.Require material dewatering, to moisture content be below 10%.
7. the material after freeze-drying is bulk bulk, through pulverizing sieve on the 20th, obtains the freeze-drying carrot powder.。
Claims (4)
1. the energy-saving preparation method of radish freeze-dried powder, is characterized in that: select fresh radish to clean, process.
2. killing cyanines processes.
3. will kill that the radish that cyanines processed is pulverized, making beating, fine grinding: the radish fine grinding requires fineness between the 600--900 order.
4. the radish slurry is placed in inspissator and carries out Vacuum Concentration: radish slurry thickening temperature requires between 50--65 degree centigrade, the drier that radish slurry method for concentration adopts band to stir; In concentrated radish slurry, require solid contents at 35----65%.
