PRO Engineering and Manufacturing Outlines the Tunnel Pasteurization Process

Milwaukee, WI – December 30, 2020 – The tunnel pasteurization process consists of taking liquid-filled bottles and cans, then running them through a tunnel constructed of stainless steel where hot waters sprayed onto the finished product, then cooled to extend shelf life.

This process is called Tunnel Pasteurization This process is an ideal way to pasteurize beverages for mass consumption.

Excerpt from a news article just released by Pro Engineering and Manufacturing:

TUNNEL PASTEURIZATION PROCESS

Pasteurization was developed by Louis Pasteur around in 1864 and has been used in the beer industry since the nineteenth century. It refers to the reduction of microorganisms in beer or other foods by heating to a regulated temperature for a specific time in order to minimize the effect on physical stability and flavor while maximizing biological stability (1).

Various organisms in beer are not pathological but affect the taste of beer (2). Draft beer is kept refrigerated and usually consumed in a short period of time, however, can and bottle beer is pasteurized for a long shelflife (1,3,4).

The shelf-life of beer has become a critical issue since it is one of the most consumed fermented beverages in the world (5). Beer’s shelf-life is determined by several factors including its microbiological, foam, colloidal, color, and flavor stabilities (6). Several months are possible if common contaminants are inactivated (7,8).

This requires a pasteurization process at a time temperature of around 60°C (140°F) for about 20 minutes as stated in the book “Brewing: Science and Practice” by Briggs, Boulton, Brookes, & Stevens (9). Heat treatment of beer is currently done by flash pasteurization, batch pasteurization, or by tunnel pasteurization in the form of bottles and cans already sealed (10). Tunnel pasteurizers are an important procedure in the brewery packaging line (11).
