Problems solved by technology

The main performance is that plate and frame filtration is used in the filtration process, the filtration accuracy is low, and the quality of the filtrate is poor. During the filtration process, diatomaceous earth and other filter aids need to be added, which will cause great environmental pollution.

Abstract

The invention discloses a continuous production method of edible grade glucose. The method utilizes secondary spraying and other processes to prepare high-purity glucose from corn starch milk. The addition amount of liquefaction enzyme and saccharification enzyme in the process is small and the process is simple. As that corn is soak in the ferrous sulfite, the corn can be sterilized, the degradation of the starch in the corn can be promote, and the subsequent glucose production can be promoted to a certain extent; The method also adopts calcium hydroxide solution to adjust pH value of starchsolution before liquefaction and saccharification, and utilizes activation action of calcium ion on liquefaction enzyme to achieve the effect of promoting decomposition of starch, thereby improving utilization rate of corn starch milk; and the invention also adopts calcium hydroxide solution to regulate pH value of starch solution before liquefaction and saccharification to promote decomposition of starch; The invention adopts activated carbon and ultrafiltration membrane to carry out secondary decolorization treatment on glucose solution, and also adopts attapulgite rod to carry out secondarydecolorization treatment on glucose solution. Bacterial cellulose microspheres adsorb proteins, fats and small inorganic salts in glucose solution.

Description

Technical field [0001] The invention relates to the technical field of glucose production technology, in particular to a continuous production method of edible grade glucose. Background technique [0002] Glucose is a kind of polyhydroxy aldehyde and the most widely distributed monosaccharide in the world. Pure glucose is colorless or white crystals, not as sweet as sucrose, and easily soluble in water. Glucose has a very important position in the field of biology. It is the energy source of living cells and the intermediate product of metabolism, that is, the main energy supply material of biology. Plants can produce glucose through photosynthesis, which is widely used in candy manufacturing and medicine. [0003] At present, the industrial production of glucose uses starch as the raw material. The existing glucose production line adopts the double-enzyme production process, including liquefaction, saccharification, activated carbon decolorization, ion exchange, vacuum concentra...
