Our malting and brewing pilot plants
and process teams offer a range of services to help develop and improve your product, and optimise production costs. We can help with
new product development - including the use of speciality malts,
new variety trials (for which our micromalting services are particularly useful), safety evaluations and process optimisation.
Amongst the many aspects of the brewing process that we can help to optimise are
dissolved gas levels, beer filtration, and
These pilot scale-based services can help you to achieve significant cost savings on time and increased flexibility in
the scope of your project. In addition, you will also gain an advantage from working with our consultants on developing your ideas and solving
problems. Our state-of-the-art facilities offer a high degree of flexibility and accurate process control.
Other pilot plant services we offer include:
It is fully quality management system accredited to ISO 9001:2008. The brewery is used for research into process and
health and safety issues, new product development, training, process technology development and appraisal and raw materials assessment.
The brewhouse comprises a mashing station, stirred mash conversion vessel and cereal cooker, wort separation by lauter
or Meura mash filter, stirred kettle and trub separation by whirlpool or hop back.
Fermentation is in 100 litre cylindro-conical fv's which can also be used as unitanks.
We have many special features installed in the brewery, including:
- carbon dioxide and nitrogen bulk gas tanks
- a gas blender enabling mixed gas products to be produced with increased ease and efficiency
- an hydrophobic gas control rig was installed for the production of de aerated liquor and for
- carbonation/nitrogenation of beer
- flash pasteurization for the production of small scale marketing trials
Packaging methods include bottling, canning and kegging using carbon dioxide or mixed gas applications.
This plant was built to bridge the enormous gap between conventional micro malting systems and the real world. It is
capable of producing malts of commercial quality and flavour which are suitable for brewing. It is fully quality management system accredited to
Steeping and germination are carried out in malting drums but the kilning takes place in dedicated units which accurately
simulate modern deep bed kilning systems.
The whole maltings is automated and can operate over a very wide range of temperature and humidity. This enables it to
mimic the many different conditions found in malting plants all over the world. The plant is used for research into process, health and safety
issues and training. It can also be used for new product development.
- control of water temperature
- control of aeration
- control of air-rest ventilation
- in-line dosing is possible
- single pass or recirculation air
- variable temperature and moisture profiles
- spray additive system
- adjustable auto-turning regime
By control of kiln recirculation by relative humidity set points above the kiln bed reproducibility of processing is
greatly enhanced which allows us to control colour and flavour. The pilot kilns can therefore produce a range of malts covering distilling malts,
white malts , Vienna and Munich style malts, therefore producing a range of colour from 2 - 100 EBC.
A roaster has been manufactured for the production of speciality malts. It is capable of producing crystal and patent
malts (chocolate and black malts and roasted barley). This extends our colour range from 2 - 1500 EBC. Products of these two plants together,
can therefore, encompass the whole range of malts seen in the commercial world.
The roaster has been successfully used for new product development eg Cara-Gold which is now widely used commercially.
Both the roaster and the pilot maltings have been used to study the use of other cereals as brewing raw materials eg wheat, oats, rye and
The pilot maltings operates on a 50 kg batch size and the roaster on a 3 kg batch size. Both plants are available for
commissioned work through our contract service system.
Campden BRI's pilot scale roaster is available for the production of speciality malts. These may be used for brewing or
as ingredients in food manufacture. The roaster is particularly useful for new product development and has already been used to develop
'Cara Gold'which is now commercially available.
Micromalting is available on 3 scales, dependent on requirements:
It can be used for a variety of purposes, such as:
- New variety trials
- Process optimisation
At Campden BRI we offer state-of-the-art expertise in current dissolved gas
control technology, with a flexible service with keg-sized volumes processed at Campden BRI and small
BBT volumes processed on-site. Our response is rapid and we offer professional back-up services in areas
of dispense and sensory to provide a complete package.
- Application of dissolved CO2/N2 combinations and oxygen removal for product enhancement
- Expertise in the use of hydrophobic membranes for the control of dissolved gases (CO2/O2/N2)
- A pilot scale gas control facility, incorporating a hydrophobic membrane
Dissolved gases case study
An international brewer was keen to develop a nitrogenated product but needed much more information on optimised dissolved gas levels.
A small number of kegs of the base brand were prepared at Campden BRI with a range of nitrogen and carbon dioxide levels. Small scale market testing by the brewer established the optimum.
The new brand has since been produced to a specification established by Campden BRI.
Beer filtration and separation
Beer and wine provide their own specific filtration, separation and flocculation
issues. These can be optimised or problem-solved with our range of facilities and expertise. Facilities
such as particle size analysis and beer and wort analysis enable us to provide a range of services to
support the processing industries
- Our "Haze Identification Service" enables troubleshooting of filtration problems caused by the product.
- Commercial appraisal of :- Novel filter aids or stabilisers, The performance of membrane filters, Current filter aid brands, Flocculant
- Measurement of the concentrations of particles as small as 0.4 μm in rough beer and assessment of the consistency of the rough beer feed
- The best available technologies for characterisation of process aids such as kieselguhr
- Photon Correlation Spectroscopy (PCS) enables unprecedented information on filter clarifying performance and therefore should enable direct
financial savings to be made in multi-stage filtration (e.g. for "cold-filtered" products)
- A definitive filter aid screening protocol, developed at Campden BRI, enabling not only the quality of filter aids to be assessed, but also
- A selection of laboratory test equipment for quick and easy assessment of the overall filterability of beer samples or simulation full-scale
filtration on the laboratory scale. The optimum filter aid regime for a given brand may be identified
In particular, if you produce membranes for crossflow microfiltration, then we can evaluate them.
Crossflow microfiltration membrane evaluation
Brewers are looking for a better, and more environmentally acceptable alternative to filter aid filtration. Crossflow
microfiltration is the best candidate to fulfil this role. Do you think your membranes are fit for the job? Yes? Then let us provide that
essential link between you and the brewing industry.
Campden BRI has considerable expertise in crossflow filtration. Comprehensive evaluations of crossflow membrane modules
for their potential use at different stages within the brewing process include:
- Optimization of operating and cleaning procedures
- Pore size effects e.g. on flux and beer quality
- Flux enhancement techniques e.g. backflushing
- Filtrate quality analysis
- Taste profiling (flavour stability)
- Long term storage (shelf-life) trials
Energy saving in wort boiling with PDX
PDX Wort Heater technology is a recent innovation that has demonstrated energy savings, typically 10% of an entire brewery's energy usage.
At Campden BRI we have a PDX Wort Heater system available in the Pilot Brewery. The system is able to assist brewers by:
- Demonstrating that the client's key brands are amenable to PDX Wort Heater technology
- Demonstrating the impressive energy savings that are possible
- Enabling guidance as to the process specifications on scale-up, shortening commissioning times in the client's brewery
