Date Vinegar Making Equipment and Completed Production Line

Vinegar is produced through a two-stage fermentation process. In the first stage, yeast (typically Saccharomyces) converts fermentable sugars extracted from dates into ethanol. In the second stage, bacteria (typically Acetobacter) oxidize ethanol. Fermentation serves as the core process for date vinegar production. During fermentation, a wide range of volatile compounds, polyphenols, organic acids and other constituents are transformed via chemical and microbial activities.

PRODUCT DESCRIPTION

Description 

We can provide complete design, fabrication, installation, commissioning, on-site technical training for operators, and turnkey projects for alcohol processing equipment with an annual capacity ranging from 1,000 to 100,000 tons.

1. Tank Configuration

The inner liner of the fermenter is made of 304 Stainless steel. Polyurethane is used as the thermal insulation layer. Designed in accordance with international fermentation standards, multiple temperature control methods are adopted. The inner tank surface is mirror-polished. It fully meets the requirements of PLC and sterilization systems. Cooling jackets comply with international standards. Plates, arched plates and corrugated plates are available to satisfy diverse requirements for cooling technologies, coolants and pressure ratings.

2. Tank System

Rotary shafts and horizontal tanks are adopted, constructed from SUS316L. Both inner and outer surfaces are polished. Design pressure: 0.25 MPa; operating pressure: 0.01–0.07 MPa. Heat transfer is realized through inner liner sleeves. Large outer ring-type jackets are equipped. Special ports for safety ventilation, exhaust and sampling are fitted.

Agitation System: Mechanical agitation with double propeller blades. Speed control: timed forward/reverse operation, adjustable from 0 to 99 minutes.

Temperature Control: Cooling water at +5°C. Pt-100 temperature sensors and electrodes, fuzzy PID intelligent controller.

Aeration Flow: 0–1 VVM (measured by tachymeter). Equipped with 0.2 μm sterile air filter. Tank pressure: 0–0.3 MPa, indicated by pressure gauge and manually adjustable.

Uniform Inoculation & Mixing: Uniform inoculation is realized via seed culture and flame sterilization. During biochemical reactions, stable and homogeneous fermentation is achieved by mixing and crushing systems.

Sterilization & Fumigation: External steam supply with manual control. Mature vinegar grains are aerated directly by steam inside the fermenter. A special mixing system is installed to realize inoculation sterilization and fumigation.
