Product Overview

The Lauter Tun Wort Recovery System is a high-efficiency auxiliary solution designed for modern brewing processes to minimize extract loss and maximize mashing yield. Positioned at the critical stage of wort separation and sparging, this system optimizes the lauter bed fluid dynamics and enhances rinsing efficiency through precise automation.

By recovering residual fermentable sugars trapped within the spent grain, it helps breweries achieve higher extract efficiency. This system is an essential upgrade for craft breweries and industrial production lines looking to scale operations, lower raw material consumption, and maintain strict flavor consistency.

Key Functions

Maximize Sugar Extract Recovery: Effectively extracts residual sugars from spent grain, increasing brewhouse efficiency by 1% to 5%.

Optimized Wort Clarification: Filters out fine particulates efficiently, ensuring excellent wort clarity before boiling.

Automated Runoff and Sparging Control: Matches the sparge water inflow with the wort runoff rate automatically to maintain optimal liquid levels.

Channeling & Blockage Prevention: Monitors bed resistance to eliminate channeling effects, ensuring every part of the grain bed is evenly rinsed.

Advanced System Components

Premium Lauter Vessel: Heavy-duty vessel featuring optimized geometry, complete with thermal insulation jackets.

Precision False Bottom: Micro-milled, laser-cut triangular wire screen panels that provide excellent open area ratios and prevent grain passage.

Raking & Cutting Assembly: Variable-frequency driven raking blades with automated height adjustment to loosen the grain bed smoothly.

Advanced Sparging Manifold: Multi-nozzle spray ring designed for uniform water distribution without creating preferential flow paths.

Sanitary Valve & Instrument Matrix: Equipped with magnetic flow meters, digital pressure transmitters, and pneumatic sensory valves for precise fluid control.

Final Inspection & Documentation
Each unit is inspected before shipment and delivered with complete technical documents, including test reports, material certificates, and operation manuals.

Working Principle & Process Flow

The system engineered for sugar extraction operates through a controlled, multi-stage recovery process:

Mash Transfer & Bed Formation: The mash is gently transferred into the lauter tun, allowing the spent grains to settle and form a uniform, natural filtration bed.

Controlled Wort Drawing: The high-density false bottom ensures uniform wort collection across the entire vessel floor, preventing channeling.

Smart Sparging: The automated sparging system introduces temperature-controlled hot water through optimized spray nozzles, evenly rinsing the remaining sugars without disturbing the grain bed structure.

Dynamic Flow Regulation: Real-time differential pressure and flow monitoring prevent vacuum compaction or bed collapse, ensuring a continuous, clear wort runoff.

FAQ

Q: Can this recovery system be integrated into an existing older brewhouse setup?

A: Yes. The system is designed with flexible piping configurations and adaptable PLC control interfaces, enabling seamless integration with existing lauter tuns, hot liquor systems, and wort transfer pumps. It can be retrofitted into most traditional or semi-automated brewhouse layouts with minimal modification requirements.

Q: How does the system prevent the grain bed from becoming stuck during rapid recovery?

A: The automation system continuously monitors differential pressure across the grain bed in real time. When pressure rises above a pre-set safety threshold, the system automatically adjusts the wort recovery flow rate. If necessary, the rake arms are activated or repositioned to gently loosen the grain bed structure, ensuring stable lautering and preventing blockage or channeling.

Q: Is the system capable of handling high-gravity brewing or heavy adjunct grains (like oats and wheat)?

A: Yes. The system is specifically engineered for demanding brewing conditions such as high-gravity wort production and high adjunct grain formulations. The variable-speed raking mechanism, combined with a precision-engineered false bottom, ensures stable filtration performance even with sticky or dense grain beds commonly associated with oats, wheat, rye, and other specialty malts.
