Flow Chart

1. Raw material inspection and feeding: purchased rice (or starch), quality request containing starch ≥80% (dry basis), moisture≤14%, there is no yellow through mildew grain of rice, which is putting into elevator geosynclines.

2. TS: rice (or starch) is lifting via elevator into the steel silo for temperate storage.

3. Cleaning destining and milling: the rice in the TS silo is elevated to the cleaning sieve and destonner to remove the impurities, then milling to fine powder with the particle size<60mesh.

4. Slurring and liquefaction: mixing the rice flour with water to make the slurry with density of 18Be, PH Value 5.6~6.0, then adding the high temperature resistance α-amylase and pumping the slurry into Jet liquefier with steam heating to 100 ~ 108 ℃ for amyloid liquefied hydrolysis.

5. Protein filtration: pumping the qualified dextrin solution (DE value about 20 or so), to the plate and frame filter for protein separation, filtering. Protein isolated from the water washing, drying, crushing, sieving, after inspection, packing and warehousing.

6. Saccharifiction: after removing the protein, the dextrin is pumped into saccharifying pot for saccharification. At this point adjust the thermostat to 60 ℃, PH value is about 4.2 ~ 4.8, add a certain amount of saccharifying enzyme, keeping about 36 ~ 50 hours.

7. 1st decoloration: heating the saccharified liquid with DE value above 97 to 75℃ to inactive the enzyme then adding the active carbon keeping 0.5~1h for absorption, then delivery to the board and frame filter for decololoring and  removing carbon. now the Light transmittance of the solution should be no less than 75%.

8. Iron exchange: Pump the solution after cooling off to 40 ~ 45 ℃ or so into the ion exchange column for anionic-cationic ion exchange process, the electrical conductivity of solution at this time to less than 20 PPM.

9. Pre-evaporation: pre-evaporating the Iron-Exchanged solution to 45Bx.

10. Isomerism: 45  Bx concentration of sugar solution will add magnesium sulfate and sodium metabisulfite, mix with sodium carbonate adjust to PH7.5 ~ 8.0 then go into heterogeneous column, after adjusting the heterogeneous column feed flow rate, the outlet of fructose content around 42 ~ 44.

11. 2nd decoloration: adding the active carbon into the material after ISO and keeping 0.5~1h then pumping to the filter to remove carbon and decoloration, now the Light transmittance of the solution should be no less than 95%.

12. 2nd Iron Exchange: after cooling the 2nd declaration solution to 30~35℃ or so, is pumping into the ion exchange column for anionic-cationic ion exchange process, the electrical conductivity of solution at this time to less than 15 PPM.

13.  F42 evaporation: concentration the solution after 2nd Iron exchange to 71Bx that is final F42 syrup. Concentration part solution to 60Bx then pumped to chromatographic separation.

14. Chromatographic separation: F42 fructose syrup after separation tower, the separation of glucose and fructose; glucose goes back to the pre evaporation and fructose goes in and mixing with F42 from the second Iron exchange and go to the next working procedure after mixed to 55.

15. Mixing bed: mixed F55 syrup goes into mixed bed, the solution should be 97% or greater light transmittance and conductivity less than 15 PPM.

16. Evaporation: after mixing bed F55 fructose syrup concentration to 77.5 Bx, namely F55 fructose syrup for finished products.

17. Filling storage: store F42, F55 into finished product tank and pump into the filling tank, quantitative loading packing container while need.
