The 500L Whiskey Mash Preparation System is designed for craft distilleries to efficiently process grains before fermentation and distillation. It integrates mashing, lautering, sparging, hot water preparation, wort transfer, cooling, oxygenation, and yeast pitching into a compact and sanitary production platform.This system is ideal for producing whiskey, bourbon, rye whiskey, grain vodka, and other grain-based distilled spirits. By ensuring precise starch conversion and high extract efficiency, it provides a stable and high-quality mash for fermentation, ultimately improving alcohol yield and product consistency. The 500L mash/lauter tun combines mashing, lautering, and sparging functions in a single vessel, helping distillers maximize sugar extraction while reducing labor and operating costs.

I. Applications

1.Whiskey Production

Suitable for malt whiskey, bourbon whiskey, rye whiskey, and other grain-based spirits. The system converts starches from malted barley, corn, wheat, or rye into fermentable sugars for subsequent fermentation and distillation.

2.Grain Vodka Production

Provides a highly fermentable grain wort that can be fermented and distilled into neutral spirits or vodka.

3.Experimental and Craft Distilling

Perfect for pilot distilleries, recipe development, educational institutions, and small-batch commercial production.

II. Main Components

1.500L Mash/Lauter Tun

The mash/lauter vessel combines mashing, lautering, and sparging operations. It features a steam-heated jacket, VFD-controlled rake system, removable wedge-wire false bottom, and efficient grain-out design.

1).500L working capacity

2).Steam-heated jacket for precise temperature control

3).SUS304 stainless steel construction

4).Variable-speed rake system

5).Wedge-wire false bottom for efficient filtration

6).Rotary CIP cleaning system

7).Sanitary polished interior

8).500L Hot Water Tank

Provides hot water for mashing, sparging, and cleaning operations. The insulated vessel maintains stable water temperatures while minimizing energy consumption.

2.Cooling System

A stainless steel tubular heat exchanger rapidly cools the mash liquor to fermentation temperature, helping protect flavor quality and reduce contamination risks.

3. Aeration Station

Introduces oxygen into cooled wort before fermentation to support healthy yeast growth and improve fermentation performance.

4.Yeast Pitching Tank

Allows sanitary inline yeast addition to ensure consistent fermentation results.

III. Technical Advantages

1.High Extraction Efficiency

The precision wedge-wire false bottom and optimized wort circulation design help maximize sugar extraction from grains.

2.Sanitary Design

All wetted parts are manufactured from food-grade SUS304 stainless steel with polished internal surfaces for easy cleaning and hygienic production.

3.Precise Temperature Control

Steam jacket heating enables accurate mash temperature profiles, ensuring efficient starch conversion and repeatable production results.

4.Easy Cleaning

Integrated CIP spray devices allow fast and effective cleaning between batches.

5.Flexible Grain Processing

Suitable for barley malt, corn, rye, wheat, and mixed grain recipes commonly used in whiskey and specialty spirits production.
