syrup making process

2018-08-27 /

Our syrup preparation machine and technology used for the glucose syrup, high fructose syrup and maltose syrup production, material usually starch or raw grains which with higher starch content. Our syrup making process also can use the rice powder to produce syrup directly, guarantee high quality of the syrup products. The syrup making process is a complete production line from starch preparation to the finished syrup produced.

Syrup making process

Below is the syrup making process introduction:
1. Material(starch / rice power) feed:
Material quality requests: contain starch (dry basis) ≥ 80%, water content ≤ 14%, then can be turned into next process.

2. Mixing and liquefaction:
Mixing starch with water, then adjust the concentration of 18Be, PH value 5.6-6.0, then add high temperature α-amylase, send it to the jet liquefier and steam to 100~108°C for liquefaction of starch. This syrup making process adopt equipments are mixing tank, jet cooker and saccharification tank.

3. Protein filtration: The liquefied hydrolyzed dextrin solution (about 20 DE value) is sent to the plate&frame filter press for protein separation and filtration, and the separated protein after washed, dried, pulverized and sieved, get protein cake, then packaging and storage, protein cake is a good animal feed, this syrup making process can get a good add-value for syrup production factory.

4. Saccharification: The dextrin hydrolyzate after separating the protein is sent to a saccharification tank for saccharification. At this time, the temperature was adjusted to 60 °C, and the pH was about 4.2 to 4.8, and a certain amount of saccharification enzyme was added for about 36 to 50 hours. Although the enzyme method for syrup making process time cost is a little large, but syrup obtained by enzymatic hydrolysis is pure, light in color, has no bitter taste, and has high quality, which is beneficial to the full utilization of syrup liquid.

5. Decolorization: The saccharification solution with the DE value of 97 or higher is heated to 75 ° C, and the activated carbon is added to the activated carbon for adsorption treatment for 0.5 to 1 hour in syrup making process, and then sent to a plate and frame filter for decarbonization and decolorization. Light rate should be ≥95%

6. Ion exchange: The decolorized solution is cooled to 40-45 ° C and sent to an ion exchange column for anion-cation exchange, and the conductivity of the solution is less than 20 ppm.

Finished syrup

7. Pre-evaporation: The pre-concentrated sugar liquid is pre-concentrated to 77.5 Bx, which is the finished syrup.

8. Storage and filling: The syrup is sent to the finished product tank for storage, and if necessary, it is pumped into the filling tank and quantitatively loaded into the packaging container.This is the last part of syrup making process.
