1. Project Background

2. Client’s Full Production Workflow

Rice soaking → Steaming → Cool to 24–26°C → Mix with koji & water in tanks → 5–7 days open constant-temperature fermentation → Filter rice residues → Dilute & blend in mixing tanks → Final filling

3. Core Client Demands

1. Open aerobic fermentation space to grow natural lactic acid bacteria for Makgeolli’s signature sweet-sour balanced taste;

2. Even temperature distribution inside tanks to avoid inconsistent fermentation between batches;

3. Uniform stirring for rice mash without sedimentation;

4. Gentle sampling without disrupting active fermentation;

5. Automatic internal cleaning to cut manual labor and meet strict food hygiene standards.

4. Custom Tank Solution & Key Features

4.1 1000L Open-Top Fermentation Tanks (8 units, core equipment)

• Open atmospheric design: Creates mild aerobic environment to cultivate lactic acid bacteria for classic Makgeolli flavor;

• Agitation motor: Evenly mixes rice, koji and water to prevent solid sediment;

• Ice water cooling jacket + thick insulation layer: Eliminates internal temperature difference, stably maintains fermentation temperature;

• High-precision PT100 sensor: Real-time accurate temperature monitoring;

• Sanitary sampling valve: Takes tiny mash samples without disturbing fermentation environment;

• Built-in CIP cleaning ball: Full automatic inner wall cleaning, low labor cost.

4.2 1000L Mixing Tanks (2 units)

Specially for post-fermentation procedures. After filtering out rice dregs, workers add water to dilute raw wine and homogenize liquid inside mixing tanks before filling, ensuring consistent flavor of finished products.

5. Project Advantages & Outcomes

1. Process-oriented design, different from standard sealed beer fermenters, fully fit traditional Korean rice wine fermentation craft;

2. Integrated temperature control system stabilizes batch flavor consistency for summit-grade tribute wine;

3. Separated fermentation & blending tanks form a smooth continuous production flow;

4. All-in-one stirring, temperature control, sampling and self-cleaning functions greatly improve production efficiency and sanitation;

5. Independent 8 fermenters support parallel multi-batch production, flexible for capacity adjustment.

   
   

6. Why Choose Our Custom Fermentation Tanks

We tailor stainless steel tanks for rice wine, fruit wine and craft beverage manufacturers, instead of providing universal beer tank sets. Our team designs every component according to local fermentation techniques, temperature requirements and hygiene standards, with full pre-delivery testing and remote after-sales guidance for overseas clients.
