Mature processes and coordinated equipment
Clear, mature process routes, coordinated equipment and simple layouts, with a small footprint and low investment requirements.
Corn Starch Sugars
Maltose syrup
Maltose syrup is used for food browning/coloring, moisture retention and taste. Typical concentration is about 75%, with syrup types differentiated by mono-, di- and trisaccharide composition.

Product overview
- Two jet-cooking stages and heat exchange connect liquefaction with saccharification.
- Includes activated-carbon decolorization, bag filtration, ion exchange, evaporation and condensate reuse; steam supply is marked 1.0 MPa.
Starch sugars include glucose, maltose and fructose syrups. Glucose syrup is generally used for fermentation; maltose syrup for food browning/coloring, moisture retention and taste; fructose syrup as a beverage sweetener.
Complete route with additions, filter residues, condensate and off-spec returns.
Figures & advantages
Low-consumption production
Low steam, electricity, acid/alkali and water consumption per unit of product. Uses mature maltose and fructose production technology.

Process notes and text version
01Complete main line
- Corn starch milk
Starch milk: food-grade NaOH and thermostable amylase; reuse of ion-exchange sweet water/condensate.
- First jet cooking
First jet: 1.0 MPa steam supplied through a steam filter.
- Second jet cooking
- Heat exchanger
Add heat-resistant amylase at the heat exchanger.
- Saccharification
Saccharification: HCl and fungal amylase/β-amylase.
- Filtration
Filtration: add diatomite and separate protein residue.
- Heat exchanger
The heat exchanger recovers liquefaction flash steam.
- Decolorization
Decolorization: activated carbon added and spent carbon separated.
- Bag filter
- Heat exchanger
- Ion exchange
Ion exchange: compressed air; spent resin and wastewater to treatment.
- Bag filter
- Evaporation
Evaporation: sterile air supply; the diagram marks off-specification return points.
- Bag filter
- Product tank
02Condensate reuse
- Evaporator condensate
- Condensate tank
- Bag filter
- Process reuse
