Lao Brewery – the brewery for country and people
The Lao Brewery, Vientiane/Laos with an annual output of 1.2 million hl beer has a market share of 99 percent in Laos. The lately installed state-of-the-art filling technology will be described in this contribution, which will also provide information on the Laotian beer market. With a per capita consumption of 20 liters per year it has quite a potential.
At the end of last year, the Dutch brewery Bavaria N. V. started using the prototype of a bottle cleaning machine which had been jointly developed by Krones and Bavaria Lieshout – the Lavatec KD 2005. With the new machine, it was hoped that the cleaned reusable glass bottles would leave the machine consistently sterile and ready to be filled with beverages, and that operating costs would be substantially reduced thanks to a simultaneous reduction in the consumption of energy, water and chemicals.
Installation of new filtration and pasteurisation technology, recentralising the brewery with a master plan for future expansion projects, building a new bottling hall housing three new lines for capacity upsizing and replacing older lines, new designs for bottles and cans, maximised modernisation and enhanced flexibility for end-of-the-line packaging: the Pilsner Urquell Brewery in Pilsen had set itself an ambitious programme over the past two years, and achieved it all in full. Thanks not least to responsive support from Krones.
Chlorine dioxide has proven to be an effective disinfectant for fighting undesired microorganisms in drinking water and processing water. Disinfection using chlorine dioxide also protects piping and surfaces against biofilm growth at very low concentration.
This contribution would like to draw attention to a fundamental change in application technology for cleaning up the water system as well as maintaining cleanliness and disinfection of machines and plants in the beverage industry. An Imeca® decontron plant has been in operation in Stiegl Brewery in Salzburg since March 2006. A year of commercial operation has confirmed the results that were presented in an earlier Brauwelt edition.
Chlorine dioxide is the most preferable disinfectant under the conditions of CIP cleaning. It is easily biologicaly degradable and has no ecologically critical byproducts. Broad clinical research has shown that there are no hazards neither for human beings nor animals caused by chlorine dioxide in its application concentrations. Using the DuoSept System, economic, ecologic and microbiological benefits could be proved in numerous bottling plants.
For some time, returnable goods have been at the centre of discussion by society at large. The focus is on aspects of process ecology, i.e. protection of the environment and resources. Extensive consideration has also been given to the economics of the returnable loop. The condition of stacking crates has, in the first instance, a major influence on safety in beverage operations and in the logistics chain. And there is also the risk of injuries to consumers due to defective crates.
Beer quality, in particular taste stability, is substantially influenced by oxygen pick-up during the production process. Numerous technological measures are taken to minimise pick-up. Also in pitching technology for large vessels, the doubling process, optimisation potential exists resulting from varying aeration and yeast addition operations.
The new KHS Innoclean SEC bottle washing machine provides outstanding cleaning results alongside ecological and economic advantages. The machine is compact in design and also fits easily into existing line equipment when substituting individual machines.
In the fermentation and beverage industries, plants are cleaned regularly using a CIP process in circulation. CIP cleaning can be done both as a stock cleaning process as well as a “run-to-waste” process. Both systems have advantages and disadvantages that will be explained below.
Horizontal and vertical cylindroconical tanks have become widely accepted during the past 40 years, both from a production point of view as well as in terms of acceptance by beer consumers. In order to guarantee production of high quality beers, scientists developed a series of quality criteria for cylindroconical tanks. This article addresses these tank criteria. Part 1 deals with tank and cooling surface sizing and Part 2, in a subsequent issue of Brauwelt International, will deal with enclosures of tanks.
