2013 Sonundan bu yana, açık renkli lager Miller Lite, Cervecería Hondureña tarafından üretilmektedir. GEA Biracılık Sistemleri, San Pedo Sula'daki (Honduras) tesiste teknik değişiklikler gerçekleştirdi.
Honduras'taki tek biracılık tesisi Cervecería Hondureña, 1935 yılında Compañía Industrial Ceibeña (1915) ve Cervecería Unión (1928) mergeri sonrasında kuruldu.
The brewery can produce up to 1.5 million hectoliters of beer and has a market share of 95 %. In 2001, it became part of the world’s second largest brewery group SABMiller.
The special challenge in this project for GEA was to integrate an almost completely automated process in a manually operated cellar. The contract scope included the engineering, the components (valves, pumps, instrumentation, electrical hardware), electrical and mechanical site management, software and commissioning.
GEA Brewery Systems took over the overall project management of the companies involved, namely Cervecería Hondureña, GEA Westfalia Separator and Pentair. The excellent cooperation of these parties was the key to a very positive project execution.
Soğuk proses alanında son teknoloji
Miller Lite konseptinin teknik gereksinimlerini karşılamak için, mevcut fermantasyon ve depoda bazı değişikliklerin yapılması gerekiyordu. Mevcut boru çiti, Miller Lite'ın özel biracılık prosesi için gereken yönlendirmeyi sağlamak için döner bükümlü panellerle donatılmıştı.
Furthermore, four dosing units were installed, including one for Tetra hops. In addition, a centrifuge, a beer cooler and a trap filter were integrated into the process.
The capacity of the water deaeration equipment in San Pedro Sula was not sufficient for the production of Miller Lite. Therefore, a new water deaeration tank was connected to the existing system via a distribution matrix with GEA double seal valves and pumps.
Sensitive measuring equipment is used in the whole process. The product is very sensitive to oxygen, so it was important to avoid oxygen uptake.
Process control technology from the specialists
Another key to success was the process automation. The Miller Lite production process required modifications in the existing process flow of the brewhouse, fermentation and storage cellar including CIP system, water deaeration system up to the filter including filtrate CIP. Especially for the integration of filtration system, the entire experience, flexibility and individuality of the GEA automation specialists was required. In the area of the fermenting room, the first operator PC was installed and put into operation, because so far there had been only a control panel for the CIP system.
After only four months of installation, commissioning and production time, the first Miller Lite beer was ready for bottling. For tasting and approval of the first Miller Lite, two SABMiller specialists came from the U.S. to the brewery in San Pedro Sula. Everyone was eagerly waiting for the judgement of the experts. Their statement decided whether the beer would be bottled or had to be destroyed. There was a big sigh of relief when a loud “That’s great!” was heard.
