Product Description

Wine Membrane - Designed Specifically for Brewing Processes

Technical Principle

The wine membrane is a tubular composite membrane with an asymmetric structure, consisting of a support layer made from high-purity inorganic materials such as aluminum oxide and zirconium oxide, produced through high-temperature calcination. The separation layer is a dense membrane prepared from functional inorganic crystals. The membrane surface is smooth and defect-free, with uniform thickness. The bond between the separation membrane and the support layer is strong, providing excellent resistance to fouling and a long lifespan, typically exceeding 5 years.

Membrane Separation Process

Recovery of Aromatic Compounds from Yellow Water

Main Functions:
* Recover aromatic and flavorful substances from yellow water, with a recovery rate exceeding 80%.
* Retrieve alcohol from yellow water with an alcohol recovery rate of over 90%.
* Capture substances such as amino acids, proteins, peptides, polysaccharides, lactic acid, and lactose from yellow water.

Enhancement of Secondary Wine Quality

Main Functions:
* Enrich aroma, reduce self-acidity, allowing ethyl acetate to concentrate by 1-fold, and reducing lactate by 1-fold.
* Remove impurities, preventing the occurrence of turbidity when alcohol content drops below 5 degrees.
* Intercept harmful substances like plasticizers and heavy metal ions, achieving a removal rate of 99.9%.

Production Process for Non-Alcoholic/Low-Alcohol Beer

Main Functions:
* Effectively remove alcohol, reducing alcohol content to below 0.01%.
* Preserve original flavor and substances.
* Recover removed alcohol with a rate exceeding 98%.

Production Process for Non-Alcoholic/Low-Alcohol Grape Wine

Main Functions:
* Effectively eliminate alcohol, lowering alcohol content to below 0.01%.
* Retain original flavor and substances.
* The removed alcohol can be used for making brandy.

Technical Features

 

1). Aroma Enrichment: Extracts soluble aromatic compounds from the liquor, enhancing its fragrance.
2). Clarification and Impurity Removal: Effectively separates alcoholic and non-alcoholic substances, contributing to the clarification and purity of the liquor.
3). Reduced Undesirable Alcohols and Oils: Effectively lowers the content of impure alcohols in the base wine or Baijiu.
4). Mitigation of Harshness: Accelerates maturation, resulting in a smoother profile and reduced harshness in new liquor.

5). Food Safety Assurance: Efficiently removes harmful substances such as saccharin, plasticizers, heavy metals, and EC (ethyl carbamate).

6). Pioneering Membrane Method: The first-ever use of membrane technology (non-high-temperature distillation) for producing high-alcohol spirits, a global first (unique innovation).

7). Room Temperature Operation: Preserves heat-sensitive substances and avoids thermal decomposition products present in the original liquor.

8). Zero Waste Production: Yields 100%, with no loss of any materials, generating no waste by-products.

9). No Additional Substances: Operates without adding any extra substances, including pure water.

10). Safest Liquor: Enriched liquor (high-alcohol spirits) is touted as one of the safest types of liquor, reflecting the enhanced safety achieved through this process.
