High fructose corn syrup introduction:
High fructose corn syrup is called HFCS for short. The saccharified liquid from enzymic method saccharified starch isomerizes part of glucose into fructose through the isomerization effect by glucose isomerase. It is a kind of mixing syrup which consists of glucose and fructose.
High fructose corn syrup can replace cane sugar. Just like cane sugar, it can be widely applied in food and beverage industry. Especially in beverage industry, it has better flavor and taste and lower price than cane sugar. Its usage has outstanding advantages in food and beverage industry.
Technology introduction for high fructose corn syrup production line:
Dry method low fat corn flour—first, we process corn with dry method by peeling, germ extracting, fat and protein removing. The whole process doesn’t touch water, and has no sewage discharge. It processes corn albumen into low fat corn flour with 70-80 meshes, and then can reach the technology requirements for producing high fructose corn syrup.
After size mixing to the suitable concentration, the low fat corn flour enters into the section of liquidation spraying. After high temperature liquidation, under the catalysis action by amylase, the seriflux with starch is converted into dextrin. Saccharifying enzyme can catalyze dextrin into glucose. Glucose can form fructose by isomerization of glucose isomerase. To get high fructose syrup with higher sweetness, we usually separate the glucose from the mixture , make it have repeated isomerization and form fructose so as to improve fructose content in the mixing syrup.
Size mixing and liquidation→saccharifying→liquid glucose decolorizing→super membrane filtration→ion exchange→isomerization→syrup refining→F42 high fructose corn syrup
Detailed information for technological process:
Size mixing and liquidation: low fat corn flour is mixed with water to about 17-19。Be。. PH is adjusted 5.0-6. After size mixing, it is added high temperature liquefying enzyme, and then reaches spraying liquidator through slurry pump. The temperature after spraying is controlled at 100--110℃, and the time for heat preservation is 60min, then the second spraying temperature is 120-125℃, for 5min. Flash evaporation reduces temperature to about 96℃ and the time for heat preservation is 2 hours. After destroying the enzyme activity, it removes the fat.
Saccharifying: it utilizes saccharifying enzyme, and saccharifies when the mash temperature reaches 58-60℃, and the saccharifying time is 24-48 hours. It goes to the next section upon reaching the required DE value.
Liquid glucose decoloration: after once and twice active carbon decoloration device, it can remove fat, protein and coloring matter in the liquid glucose.
Super membrane filtration: after decoloration, when the clear liquid passes inspection, it can enter into the membrane filtration system to remove the soluble protein in the liquid glucose and reduce the protein content.
Ion exchange: it adjusts the liquid glucose temperature and PH value and cools temperature before exchange. The liquid glucose pumps into ion exchange system for desalination and remove the ash on the liquid glucose.
Concentration: after desalination, under vacuum conditions, the liquid glucose is heated for evaporation. When the liquid glucose concentration reaches the range that the technology requires, then it cools the temperature and enters into the next section.
Isomerization section: after adjusting acidity, concentration and the microelements of the syrup, it enters into the heterogeneous column. Under the immobilization isomerase effect, it isomerizes glucose into fructose and produces 42% original syrup.
Syrup refining: we process the original syrup by secondary decoloration, refining exchange, secondary concentration, compound preparation, and temperature adjustment, then pump it into the end products tank for storage. This is end products F42 high fructose corn syrup.
High temperature ejector, bundle dryer, ion exchange column, second effect evaporating tower, candle filter, wet mill.
1. It adopts high temperature liquefying enzyme and two sections of spraying and liquidation technology. It controls the temperature by segmentation. It damages enzyme activity by high temperature to make enough starch liquefacation and complete albuminous degeneration without retrogradation. DE value is controlled 10-17%，and it has high starch yield rate.
2. It adopts flash vaporization and separates starch and the bran under high temperature. More than 90% of protein, fat and liquid glucose is completely separated.
3. Twice reverse-flow active carbon decoloration technology has long time of absorption and bleaching. It has strong absorption capacity for liquid glucose, residual fat, color and ash after layer filtering. It also has strong removing ability to liquid glucose organic impurity, which can furthest reduce the impact on the liquid glucose by protein fat color to ensure end products color and warranty period.
4. Second level ion exchange column and liquid glucose refining technology, removes low fat corn flour ash content sufficiently, raises the temperature for sugaring off and reduces discoloration problem.
5. There has Residual heat recovery design for the water and gas of the whole production line. The liquidation secondary steam recycle, ion exchange and water replacement, plate in exchange for water and evaporation condensation water recycle can save energy and reduce cost.
6. There has no wastewater discharge. The environmental protection cost is low and it conforms to the national industry policy.
7. The total investment is only 1/3 of the traditional wet method.
