19/04/2018: The malting business

by Cimbria, Denmark

Cimbria has been involved in the malting industry for over 40 years and is a leader in supplying cleaning, drying and conveying equipment for malting barley and dry malt processing equipment.

In the UK, there are five main malt production companies and they all have three or more sites producing malt for UK brewers and the distilling industry in Scotland. Last year, Cimbria equipment was installed on three projects in the malting sector in different areas of the malting process.

Starting at the beginning of the malting process – barley dressing
Crisp Malting Group needed to replace their old barley dressers and hoped to improve the sample at the same time; they chose the Cimbria Delta 116 for the project. The building was quite restricted in terms of space, but due to improvements in cleaner design they were able to get greater screen area and a more effective aspiration system to clean out the dust and barley awns more effectively with the new cleaner. Improved quality of malting barley going to steep was achieved at a capacity of up to 23 tph. A Cimbria Delta 145 for cleaning malt at 30 tph was also included within the scope of this project.

The dressed malting barley then goes to be steeped, changing the density and flow characteristics of the barley. Moisture content is increased to 45 percent with some germination already taking place.

Bairds at Witham, one of Cimbria UK’s longstanding malting customers, had a wet pumped blow line system for conveying steeped barley to the germination vessels that needed to be replaced. The Cimbria proposal was to use six Cimbria Contec screw conveyors of the type SUH 500, discharging the steeps at 90 tph using low flight speeds to reduce damage to the germinating malting barley. De-watering outlets remove excess water from the conveyors, whilst hinged lids allow the machines to be cleaned down manually by pressure washer between batches. The customer is pleased with the robust equipment. Discharge capacity has exceeded expectations and the system has helped improve germination yield of the malting barley.

Steeped barley then germinates in vessels to become green malt and is kiln-dried to become the final product – malt. The malt is de-culmed and dressed prior to going out to customers in bulk or bag.

Simpsons Malt wanted to upgrade its existing 20 tph malt dressing plant. The existing equipment was not fast enough, so Cimbria proposed 2 x 146 Combi Cleaners mounted back-to-back, which would easily give 60 tph dressing and polishing of the malt prior to bulk discharge for delivery to its customers. Cimbria continues to develop equipment for the malt production process and recognizes the importance of this sector to its business.
