Combined Hot Liquor/Mash/Laute Tank System For Brewhouse System

May 13, 2023

A combined Hot Liquor/Mash/Lauter Tank system is a common setup in a brewhouse. This system allows for the efficient production of wort, the liquid extracted from the mashing process, which is then fermented to produce beer. Here's how it typically works:

Hot Liquor Tank (HLT): The HLT function involves heating and storing hot water used in the brewing process. In a combined system, the vessel acts as an HLT section. It is equipped with heating elements or jackets to heat the water to the desired temperature for mashing.

Mash Tun: The mash tun is where the mashing process takes place. In a combined system, the vessel also functions as a mash tun. It is designed with features like mixing mechanisms, temperature control, and insulation to facilitate the mashing process. Hot water from the HLT section is mixed with malted grains, allowing enzymatic conversion and sugar extraction. 

Lauter Tun: The lauter tun is responsible for separating the liquid wort from the spent grain material after mashing. In a combined system, the vessel incorporates mechanisms like a false bottom or filter system for the lautering process. The vessel allows the wort to be drained or pumped out while retaining the grain material.

The combined hot liquor/mash/lauter tank system simplifies the brewing process by reducing the number of vessels required and optimizing space utilization. It allows for an efficient and continuous brewing operation in a compact setup. Once the mashing and lautering processes are complete, the liquid wort can be transferred to a separate vessel, such as a brew kettle, for boiling, hop additions, and subsequent fermentation.

It's important to note that the specific design and features of a combined hot liquor/mash/lauter tank system can vary among manufacturers and breweries. It's advisable to consult the equipment manufacturer or supplier for detailed information on a particular system's capabilities, specifications, and operation.

What capacity of brewhouse is suitable for combined Hot liquor/mash/laute tank system

The suitable capacity of a combined hot liquor/mash/lauter tank system for a brewhouse depends on various factors, including production volume, brewing frequency, and specific brewery requirements. Here are some general guidelines to consider when determining the capacity:

Space Constraints: Evaluate the available space in your brewery. A combined system offers space efficiency compared to separate vessels, but it still requires adequate room for operation, access, and maintenance. Ensure that the chosen capacity fits comfortably within your available space without compromising workflow or safety.

Brewing Frequency: Consider how frequently you plan to brew and the turnaround time between batches. If you have a high brewing frequency, you may need a larger capacity system to accommodate the volume and maintain a steady production flow. Conversely, if brewing is less frequent, a smaller capacity system might be sufficient.

Growth Potential: Factor in your future growth plans. If you anticipate an increase in production volume over time, it may be wise to invest in a system with a larger capacity than your immediate needs. This can help avoid the need for upgrading or replacing the system too soon.

Efficiency Considerations: Consider the efficiency of the brewing process. A combined system should have appropriate heating and mixing capabilities to achieve efficient mashing and lautering. Ensure that the chosen capacity allows for proper heat transfer, consistent temperature control, and efficient mixing of the mash.

Production Volume: Assess your target production volume per batch or brewing cycle. This could be based on your anticipated demand or business plan. The capacity of the combined system should be able to handle the desired volume efficiently. Common brewhouse capacities range for small-scale systems, such: 5bbl brewing sysem and 7bbl brewing system and 10bbl brewing system.  

What advantage for combined Hot liquor/mash/laute tank system for brewhouse system

The combined hot liquor/mash/lauter tank system offers several advantages for a brewhouse system. Here are some of the key benefits:

Space Efficiency: Combining the functions of hot liquor tank, mash tun, and lauter tun into a single vessel saves valuable space in the brewery. This is particularly beneficial for smaller breweries or those with limited floor space. By eliminating the need for multiple separate vessels, the combined system optimizes the use of available space.

Cost Savings: Investing in a combined system can result in cost savings compared to purchasing separate vessels for each function. It reduces the initial capital expenditure required for acquiring individual tanks, as well as the costs associated with installation, piping, and other associated infrastructure.

Streamlined Workflow: With a combined system, the brewing process becomes more streamlined. There's no need for transferring wort between different vessels, which saves time and reduces the risk of contamination. It simplifies the brewing process by consolidating mashing and lautering operations into a single vessel, promoting efficiency and productivity.

Improved Temperature Control: The combined system typically incorporates advanced temperature control mechanisms. These mechanisms allow precise temperature management during mashing, ensuring optimal enzyme activity and sugar extraction. Efficient temperature control contributes to consistent beer quality and repeatability of recipes.

Enhanced Efficiency: The integrated design of the combined system enhances overall brewing efficiency. It reduces heat losses during transfers, minimizes the risk of stuck mashes, and improves wort clarity during lautering. The system may also feature efficient mixing mechanisms to facilitate thorough mash hydration and extraction.

Ease of Operation and Maintenance: Operating and maintaining a combined system is generally simpler compared to managing multiple vessels. Breweries with limited staff or resources can benefit from the ease of operation, cleaning, and maintenance that come with a single vessel.

Flexibility and Adaptability: Combined systems are often designed to be versatile and adaptable to different brewing styles and recipes. They can accommodate various batch sizes and recipe variations, allowing for flexibility in production.

It's important to note that the suitability and advantages of a combined hot liquor/mash/lauter tank system depend on the specific needs and circumstances of each brewery. Considering factors such as production volume, space availability, and budget constraints can help determine if a combined system is the right choice for your brewhouse.

As for installation for combined Hot Liquor/Mash/Laute Tank System For Brewhouse System

Installing a combined Hot Liquor/Mash/Lauter Tank system for a brewhouse involves several steps. Here's a general outline of the installation process:

Plan and Design: Start by thoroughly planning and designing the system. Consider factors such as available space, utility requirements (electricity, water, steam), process flow, and safety regulations. Consult with professionals, such as brewery equipment suppliers or process engineers, to ensure the system meets your specific needs.

Prepare the Space: Clear and prepare the designated area where the system will be installed. Ensure it has adequate ventilation, proper drainage, and suitable flooring that can handle the weight of the tanks and associated equipment.

Obtain Necessary Permits: Check with local authorities or regulatory bodies to determine if any permits or approvals are required for the installation of the brewhouse system. Obtain the necessary permits before proceeding further.

Install Utility Connections: Depending on the specific system and your brewery's infrastructure, you may need to install utility connections such as water, electricity, and steam lines. Engage professionals or contractors with experience in brewery installations to handle these tasks safely and accurately.

Position the Tanks: Determine the optimal layout for your brewhouse system, considering factors such as space constraints, workflow efficiency, and accessibility for maintenance. Install the Hot Liquor, Mash, and Lauter tanks in their designated positions, ensuring they are properly leveled and securely anchored.

Connect the Tanks: Install the necessary piping and valves to connect the tanks together. The specific connections will depend on the design of your system, so follow the manufacturer's instructions or consult with a professional to ensure correct installation.
