Embodiment 1
[0009] The preparation method of the special starch syrup for QQ sugar in this embodiment includes the following steps: (1) pulping and liquefaction: use deionized water to adjust the cornstarch milk to 17.5Bé, adjust the pH value to 5.5, and prepare the prepared cornstarch Add high temperature resistant α-amylase 0.4kg / tds to the milk, the first spraying temperature is 105°C, the first flashing temperature is 100°C, the second spraying temperature is 132°C, the second flashing temperature is 85°C, after liquefaction DE value is 17%; (2) High-temperature filtration: After liquefaction, the feed liquid is kept at 85°C and directly enters the SEDICANTER® S 6E double-cone decanter screw separator to separate and remove large solid particles such as flocculation protein. ≤25m 3 / h, the rotating speed of the drum is 3650 rpm, the differential speed between the screw and the drum is 29.6 rpm, the temperature of the separation medium is 0°C, and the pH value is 4; (3) Low temperature...
