MILLING

Efficient brewing starts with great milling. The design of CLE Brew Systems mills have been proven to help you get the most out of your grain by using optimized milled spiral fluting patterns on the rollers, with an easily adjustable roller gap to provide for different grain types. This ensures that the grain husk is conserved along with the optimal grinding of the endosperm. Our milling systems will help you get the most out of your grain by using technology to optimise sugar extraction from the grain, while maintaining the integrity of the grain husk for efficient lautering.

Performance through Efficiency

We can fulfill all of your milling requirements through our unique and customised design of milling equipment, from fully automated sequencing and monitoring to gravity fed grist from the mill to the mash tun.

Effective milling improves the extraction yield from the grain, increasing the efficiency of the milling process so you get more out of your grain. By adjusting the gap between the rollers you can optimise the crush of the different types of grains, such as using a larger roller gap for the more brittle crystal malts.

Consistently Great Beer

Great beer starts from using the freshest ingredients and the best equipment for these ingredients. CLE Brew Systems can provide you with excellent equipment that will give you high quality worts, from customised rollers to efficient grist hydrators. Our mills will crush the grain in such a way to ensure optimal extraction and subsequent leaching of the wort from the grain in the lauter.

CLE Brew Systems’ mills are ideal for providing high quality crushed grain with the flexibility of changing the crush type for the different types of malts. Thanks to our unique engineering, our mills will help you get the most out of your grains by providing the perfect shearing technology  that maximises the surface area of the endosperm for better sugar extraction without compromising the husk.

What makes our mills so great?

  • Hygienic design for easy cleaning and non-contaminating.
  • Grain weight recording in grain hopper
  • Grain mill timer
  • Optimized grist hydrator spray geometry to avoid mash balling and flotation
  • Grain feed to mill speed control
  • Precise and easy adjustment of the roller crushing gap
  • Automatic start-up and shut-down in sequence of milling equipment, from grain hopper to grist auger.
  • Dust free

WORT TREATMENT

Treatment of the wort obtained after lautering has a major influence on the final beer quality. The wort is boiled which enables many physical reactions to occur, such as the formation of hot break, removal of organisms and unwanted flavour compounds are boiled off, the hot temperature is required for the conversion of hop components so that they are dissolvable in the wort.

 

Efficient boiling technology

CLE brew systems kettles utilize strategically placed steam dimple pads or elements that provide a great rolling boil in your kettle which is needed to produce the required physical chemical reactions in the wort and to also get the best utilization out of your hops.

We have had many reports on caramelisation reactions on the high temperature elements in direct contact with the wort imparting the beer with a great and unique flavour.

Our kettle give you the right amount of evaporation each time. With CLE wort boiling technology you can be satisfied  your wort will get the best hot side treatment possible.

 

Whirlpool

After wort boiling, the wort is circulated around the vessel to assist in hot break removal. The whirlpool has a base design that is optimized for solid (hot trub) deposition and removal from the hot wort. The whirlpool effect is well known to remove the solids from a liquid and CLE brew systems used applied engineering technology to achieve this to its full potential taking into account person vessel design preferences, such as height limits and kettle/whirlpool combination vessels.

CLE Brew Systems whirl pools compromise technology that is based around the relationship between fluid dynamics and the properties of hot wort. When designing a whirl pool, CLE Brew Systems takes into account fluid flow dynamics and its relationship with the wort properties, vessel and the wort inlet and outlet geometry, as well as the arrangement of the wort outlets. By taking these into account, this means that our whirl pools help you create a really compact trub cone in the centre of the whirpool and this can be replicated time and time again with maximised hot wort recovery.

 

Wort cooling

Fast wort cooling is crucial after whirlpooling as that is when potential microbial infection is high. A high quality and easy to clean heat exchanger is crucial for fast and efficient wort cooling.

 

Power saving wort cooling

Not only is our heat exchanger one of the best, its cools your wort fast and efficiently while also providing you with hot water for your next brew and cleaning

Power saving and single-stage cooling

With our pre-heat exchanger filter you no longer have to worry about your heat exchanger having particulates collect on the walls and making the exchange of heat between your hot wort and cool water less efficient. Cold water is set to 1 deg C so that the wort is cooled with only one pass through the heat exchanger and wort cooling time is kept to a minimum.

MASHING

Gentle and Efficient

The quality of the mash is affected by many process parameters of the mash tun. Temperature, agitator design and speed and vessel wall temp all affect the biochemical and physical reactions of the mash and these reactions determine the mash quality and the end character of the finished beer.

Pure Innovative Engineering

The mashing process may seem simple, but there is a lot of important things going on in the mash tun that you cannot see. The impact of these factors on the conversions happening in the mash tun have considerable importance when designing a mash vessel and must be taken into consideration. When designing our mash tuns we make sure they have all the necessary features to meet optimal mash conversion requirements. This starts with equal temperature distribution in the mash, especially as it is hotter near the sides of the vessel. We specially engineer an efficient mash mixer with low shear capabilities along with efficient dimple pads to help with uniform heat distribution and transfer throughout the mash.

We used specially designed pumps for mash transfer from the lauter tun to minimise shear forces and the breaking up of particles, all which affect lautering efficiency.

LAUTERING

Your malt is one of the most expensive ingredients in the brewing process, so it is important that you get the most efficient use out of it. With a CLE Brew Systems lauter we will help you minimise your lauter time, maximise wort extraction and minimise cleaning times.

Our Lauter tun design is based on integrated lautering technology with expert skills in stainless steel fabrication, such as optimised wort draw off points, highly efficient raking machine  with mash discharge sweeper arm, maximised surface area of the wedge wire screen, plus automation of rake system which can include lowering and raising of the rake arm in response to differential pressure changes.

To assist with consistently clear and great quality wort, all of our lauter tuns contain a sight glass after the collection ports so that you can visually see the clarity of the wort before diverting to the kettle. This minimises recirculation times and helps with the reproducibility of recipes.

 

Optimised Extraction for Maximum Yeilds

Our lauter design is based on maximising sugar extraction while minimising the leaching of unwanted products from the grain. To help with this we mount our raking system on the top of the vessel which allows for a greater surface area and a more uniform filter screen. Wort run off channel placement is designed for uniform wort runoff and equal bed pressure. Our rakes consist of both cutting and lifting knives as well as bent knives for maximised mash mixing with minimised damage to the grain husk.

FERMENTERS/UNI TANK

All of our fermenters are design verified and comply with all relevant codes and regulations. Our fermenter design also features an unique adjustable racking arm that can change the position of the draw off point in your tank, sight glass on the end of the racking arm to analyze the clarity of the wort at the bottom of the cone, stainless steel fermenter bubblers for one-way hygienic gas release.

CIP SYSTEMS

Recoverable, portable and efficient cleaning system.

We know the importance of a great cleaning set up, especially one that guarantees no contamination of the product, is easy to use around the brewery, and cleaning product is contained and can be recovered. We will personally customise and make your own CIP system, from a complete portable CIP unit to a fixed vessel, taking into account environmental considerations and your own cleaning regime.

Detergent costs, water consumption and waste water requirements, as well as the brewing and cleaning procedures themselves can impact the cleaning regimes for the brew system. Cleaning of the brew system and tanks is done by the use of strategically placed spray balls. Cleaning solution can then be circulated around the tank for a full clean. This gives you consistently clean tanks and pipe work and ensures a high quality product.

BREW SYSTEM DESIGN CONSIDERATION

Some of the things we take into account when designing and planning a brew system are:

  • optimum and unique piping concepts, which focuses on flavour
  • stability during transfer.
  • designed for ease of access
  • pre-piped brew house for fast and easy installation.
  • minimal product stress and losses during transfer
  • low maintenance
  • incorporation into existing brewery processes
  • optimised valve placement
  • SEMI-AUTOMATIC CONTROL
  • CLE Brew Systems provides a unique automation system that can be incorporated into any brewery. A combination of our very own automation program along with automated valves makes brewhouse control and data recording very easy. This program controls the relevant processes; mashing, lautering, wort boiling, whirlpooling, heat exchange and fermentation and conditioning, and records and maps data for these processes in real time, such as fermentation temperatures. The interaction screen is very easy to use showing an optimised and easy to navigate placement of the vessels, valves and switches in the brew house, as well as process parameter monitoring, curve visualisation and brew reports.
