Embodiment Construction

[0018] specific implementation

[0019] Embodiments of the present invention: the implementation of the present invention will be further described below in conjunction with the accompanying drawings. Accompanying drawing shows the extrusion cooking device of the starch syrup raw material that implements the extrusion cooking of the present invention and adds enzyme preparation. The first screw rod 1, the second screw rod 6 and the third screw rod 10 are sleeved on the main shaft 15 and rotate together. The speed is 30r / min-260r / min.

[0020] Among them, the starch syrup raw material before extrusion cooking is crushed and passed through a sieve with an aperture of 2-5mm, and the moisture content is adjusted to 20%-45%. At the same time, an appropriate amount of enzyme preparation is added to adjust the pH value to 4.2-7.2. The starch syrup raw material powder of the enzyme preparation enters the extrusion cooking device from the feeding port 3 (see the attached figure), and...

Abstract

The invention belongs to a processing method, a processing apparatus and saccharification method of starch sirup material of the extrusion cooking additive enzyme preparation in the starch sugar process. The main technical characteristics are: providing extrusion cooking apparatus of amylum sirup material of the additive enzyme preparation, the best parameter of the extrusion cooking system and glycation method of using the extrusion cooking starch sugar, smoothening the saccharification, and filtration of the saccharification liquid. Compared to present starch sirup production by using two kinds of enzyme not extrusion cooking starch sirup material, the invention reduces the saccharification time to 1 / 2 to 1 / 3 when achieving the same saccharification liquid DE value by not extrusion cooking starch sirup material.

Description

technical field [0001] The invention belongs to the technical field of a processing method, a processing device and a saccharification method of a starch sugar raw material which is extruded and cooked and added with an enzyme preparation in a starch sugar production process. Background technique [0002] At present, domestic and foreign scholars and enterprises use double enzyme method to produce corn starch syrup. The production process is: corn—cleaning (removing impurities)—soaking—wet separation of germ—separation of fiber—separation of gluten (isolation protein)—starch milk— Gelatinization and liquefaction (adding temperature-resistant α-amylase)—saccharification (adding glucoamylase)—syrup (Liu Yawei.
