Erythritol Production Solution
Erythritol (also known as tetritol, molecular formula C₄H₁₀O₄) is a natural functional sugar alcohol with zero calories and low sweetness. Its sweetness is approximately 70% that of sucrose, earning it the name "zero-calorie sugar." It is the only purely natural, calorie-free sweetener among sugar alcohols. Erythritol is produced from starch or sugars such as corn and glucose through microbial fermentation.
We provide a full set of services from design (process, civil, electrical), manufacturing, installation, commissioning to after-sales service; accurate 3D design, constructing 3D solid model, showing every detail of the project intuitively, accurately ; advanced automatic control system, ensuring the automatic and smooth operation of the entire production line.
Process Description

01
Fermentation
Fermentation
Erythritol production employs an aerobic fermentation process, requiring continuous sterile air supply to maintain microbial metabolic activity. The core of fermentation lies in optimizing culture conditions, including:pH value、temperature control、substrate (dry matter) concentration、dissolved oxygen level、specialized nutrient formula (fermentation supplements).

Refining
Refining
The fermentation broth contains numerous impurities (e.g., microbial cells, proteins, polysaccharides) and requires multi-stage purification:
Microbial Cell Removal: Tubular ceramic membrane filtration is used to efficiently separate yeast cells.
Macromolecular Impurity Removal: Organic nanofiltration membranes remove residual protein peptides, polysaccharides, and other impurities, reducing broth viscosity and improving efficiency in subsequent processes.
Deep Purification: Processes such as desalting, evaporation concentration, crystallization, and centrifugal separation yield primary wet crystals.

Filtration and Decolorization
Filtration and Decolorization
The refined erythritol solution undergoes further purification through recrystallization:
Crystallization: Erythritol precipitates from the solution, forming high-purity crystals.
Separation and Drying: The crystals are separated via centrifugation and dried to obtain a standard-compliant final product.
Mother Liquor Reuse: A multiple mother liquor recycling process is employed to improve yield and minimize waste.
The final product is high-purity white crystals with minimal residual impurities.
