Brewing equipment review.

Vendors offer improved brewhouse, packaging and lab equipment for brewers large and small.

Custom stainless brewing equipment

Santa Rosa Stainless Steel specializes in steam-fired brewhouse equipment, which the company says provide "greater flexibility and more precise temperature control than direct-fired systems."

The company is ASME certified to manufacture pressurized fermentation, lagering and bright beer tanks. Santa Rosa also fabricates advanced design mash mixers and cookers to individual specifications. The company builds wort kettles with either steam jackets or coils in the kettle bottom for preheating the wort. For wort boiling, Santa Rosa reports the kettles feature internal, high efficiency tubular boilers. Designed for low or high pressure steam, the company says these internal cookers "deliver rapid heating and high evaporation rates with minimal foaming - and they are also designed for easy cleaning."

Santa Rosa has also developed equipment suitable for high performance lautering systems. According to the company, "Lauter tuns from Santa Rosa Stainless Steel ensure efficient, uniform leaching of extract over the entire lautering area. Minimal under-plate volume means less foundation water and dilution, The planar bottom is absolutely level, with a minimum of one wort outlet for each square meter of false bottom area, and a centralized wort collector, and full-cone sparge nozzles, for either continuous or batch sparging, ensure an even distribution of sparge water."

In addition to conventional machined slot designs, Santa Rosa also offers false bottoms of the wedge-wire type.

Spent-grain raking is accomplished with a specially designed system of rakes and plows for efficient lautering. The company says that its straight and zig-zag knives loosen the grain bed without disturbing it on the false bottom, "ensuring a smooth runoff of bright wort."

Santa Rosa's lauter tuns normally come with closed lautering systems, which the company says provide effective control, proper flow velocities, easy cleaning, minimal air pickup. All Santa Rosa brewhouse piping systems are designed to these same standards, the company reports. Technicians at Santa Rosa can pre-assemble systems, partially break them down for shipping and quickly reassemble them at a client brewery.

Santa Rosa Stainless reports that it can provide anything from a single uni-tank to a complete turnkey system, with 25- to 100-barrel knockout wort capacity.

Enerfab builds Pittsburgh brewhouse

Enerfab, Inc. of Cincinnati, OH, has been serving the brewing industry since 1901. One of the company's recent projects was replacement of brewkettles at the Pittsburgh Brewing Co. in Pittsburgh, PA. The company installed two new 600-bbl kettles, removing the old kettles one at a time so that the brewery could continue production. Enerfab removed and disposed of the old copper kettles and removed and reinstalled percolators and new copper stem coils. The company also furnished and installed a 36-inch diameter 304 stainless steel stack in the brewhouse, furnished and installed new CIP lines, added a new stainless steel insulation casing and polished the stainless to a number four finish. The new kettles, made of 304 stainless steel with copper internal coils, are now busily turning out Iron City beer.

Another recent project involved installing a new brewhouse at the Mendocino Brewing Co.'s Ukiah, CA, brewery. For that installation, Enerfab put in a mash mixer, lauter tub and brewkettle (see photo).

Enerfab provides a wide range of products and services for the brewing industry. The company's capabilities include designing, installing and starting 100-barrel or larger brewing systems, as new installations or as replacement for existing brewery equipment.

APV Heat Transfer Technologies

APV Americas produces deaeration plants for brewing industry applications. According to the company, APV can offer two types of package plants depending on the level of deaeration needed.

A single-stage plant is operated at ambient temperature and can produce oxygen levels as low as 0.5 ppm, depending on initial concentration. Typical standards vary from 3 to 200 GPM of product.

Two-stage systems are used to reduce the dissolved or entrained oxygen levels in process water. Operating at 50 degrees Fahrenheit, oxygen levels as low as 0.05 ppm can be obtained by injection of 0.25 volumes of carbon dioxide. Standards ranging from 8 to 400 GPM are ideal to meet the needs of brewery and soft-drink industries.

APV also reports that it can supply a single-stage system requiring steam heating for cases where thermal pasteurization of the process water is critical as the final oxygen content.

As APV notes, dissolved or entrained air can seriously affect product quality at all stages of the brewing process. In the brewhouse, oxygenated brewing and sparge water affects color, foam and taste. APV says that oxygen pick-up in beer can be reduced by using deaerated water in the diatomaceous earth filtration mix tank, precoat run and beer transfer lines. As well as being an essential ingredient in blending high gravity beer, deaerated water can be used to produce low-alcohol or alcohol-free beer by dialysis technology.

The APV two-stage deaeration process, originally developed by APV Rosista in Germany, provides a method of reducing dissolved or entrained oxygen levels in process water. Operating at 50 degrees Fahrenheit, oxygen levels as low as 0.05 ppm can be obtained by two-stage vacuum deaeration and injection of 0.25 volumes of carbon dioxide.

Meheen builds micro bottler

The Micro Master is a fully microprocessor automated, four-head filling and capping machine from Meheen Manufacturing of Pasco, WA. According to the manufacturer, the machine can produce 1200 bottles per hour with minimal air pick up.

The company says that it "is the only beer filler in the world which uses a microprocessor to actively manage bottle purging, pressures, fill levels and beer foaming." The company says the unit is reliable, easy-to-clean, portable and boasts automatic filling, sanitizing and cleaning.

Meheen says that all movement on the machine is accomplished using pneumatic cylinders - even bottle movement, eliminating the need for a conveyor. The bottle conveying system on the Micro Master uses a sloped table, and the bottles slide down by gravity to an indexing plate that pushes the bottles to the correct position. All other mechanical features are also pneumatic, including a tubing pinch valve to control beer flow, fill head movement and capping of bottles.

The unit does not include a pressure bowl, which the company says eliminates the need for CIP equipment and complicated cleaning procedures. The Micro Master uses a beer hose from the clear beer tank to the bottle, controlled by pinching the hose shut. Both cleaning and sanitizing can be accomplished using a small pump to move solution through the machine, Meheen says.

To reduce air pick up, the company says the Micro Master is a long tube filler with complete bottle purge. Filling and purge tubes reach near the bottom of the bottle and fill from the bottom up. "This filling configuration ensure complete purging of the atmosphere from the bottle and minimizes turbulence while filling," the company says.

Meheen says that the machine can achieve still pours and capping on foam by using its microprocessor to manage the pressures and a CO2 pulse into the beer. The CO2 pulse creates seed bubbles in the beer causing it to foam, and the foaming takes place while the bottles are moving from the filling head to the capping head, one bottle length away.

For more information, contact Meheen Manufacturing, Tel: (509) 547-7029.

"Micropub" brewing stations

Micropub Systems International has introduced a "Second Generation Micropub" brewing station. The company says it can provide complete installation support, brew training, and recipes to install a brewing station in 100 square feet. The company says it is "the most compact, affordable and simple brew system available." And Peter Psyllos, owner of the Distillery in Rochester, NY, offers a testimonial: "Having the [Micropub] system has increased our food sales 30% and we have seen a steady increase in beer sales."

Hilge Pumps

Shanley Pump & Equipment of Arlington Heights, IL, offers a full range of Hilge pumps for every brewing application: hot and cold water, mash, whirlpool, unfiltered beer and bright beer. The company also sells filling pumps for kegging and bottling and cleaning pumps for caustic and cleaning solutions.

The company says that Hilge pumps are made with a cold-rolled stainless steel case, providing a smooth and clean surface. In addition, Shanley says that the pumps incorporate "sensi-flow" design, for "gentle handling, and quiet transfer of your products, as well as an open, easily cleaned-in-place design."

The "Sensi-Flow" system uses long, hydrodynamically-shaped impeller blades and impellers to reduce velocity gradient and minimize shear. According to Hilge, the pump housings are designed so that liquid particles are smoothly engaged instead of colliding and the liquid only moves in streamlines.

The pumps include the Hygia Super (pictured) which is a single-stage, end suction, centrifugal pump, made using close-coupled construction in 316Ti stainless steel. The company says it is ideal for high-moisture laden areas for product feed, circulation or transfer.

For more information on Hilge pumps, contact Shanley Pump 7 Equipment, 2525 S. Clearbrook Drive, Arlington Heights, IL. Tel: (847) 439-9200.

Gusmer sells lab analyzer

The A. Gusmer Co. of Cranford, NJ, is now offering the Aber Series Lab Yeast Analyzer, produced by Aber Instruments of the United Kingdom. In common with the Aber Instruments on-line "yeast monitor", the company says the lab version measures the viable yeast cell concentration by capacitance and can be used for a range of brewery samples, including yeast slurries and fermenting wort. Samples of 15ml volume can be analyzed with high accuracy and repeatability, Aber says, without the need for dilution and manual counting under a microscope or the addition of dyes.

Aber says only viable cells are measured, so the lab yeast analyzer can be used on yeast slurry samples to allow the brewer to calculate accurately the amount of yeast to pitch at the beginning of fermentation and reduce some of the variability in fermentation time. Aber says that the instrument reading will not be affected by varying levels of trub in the slurry, a common source of error when estimating yeast cell concentration by centrifugation.

Aber says the lab yeast analyzer has been designed for use by lab staff and process operators and uses microprocessor technology.

For information, contact Jack Ehmann at A. Gusmer Co., Cranford, NJ. Tel: (908) 272-9400.

Malt Mills

HDP Brewing Systems of Canada is one of North America's leading malt mill producers, building low-profile units that can be mounted under storage or conveying structures. The company reports that its malt mills feature instant micro dial adjustment of roll gap settings, heavy-duty coil spring safety releases, lifetime bearings and central lubrication manifold and a sampling port for grist analyses during milling.

The mills include motors, belt and pulleys, intake hopper, hopper screens and hopper mounted magnets and slide gate shutoffs to govern flow.

According to HDP, the mills can help provide faster lautering, higher brewhouse yields, lower malt costs and "crystal clear lautering."

Pub Brewing Co. small-scale installations

The Pub Brewing Co. of Mahwah, NJ, offers 7, 10, 15, 20 through 125-barrel brewing plants, designed and installed by a staff of engineers, master brewers and fabrication experts.

The company reports that it has developed a two-stage single-vessel brewhouse, patent pending, for a modified decoction process. The company's larger micro-style brewhouses incorporate another design using a single hydraulic pump to operate all phases of the cycle.

"Our breweries are kept simple to allow brewers to continue processing product instead of waiting for a specialized technician to arrive to repair or replace a component," the company says. "The reason for this simplicity is the fact that we provide equipment to brewenes in remote regions - from China, to Russia, South America to Kazakhstan, we provide a simple, easy-to-maintain and operate turn-key brewery."

Pub says that its standard turn-key brewery uses basic electrical processes and heating components that can be repaired or replaced by general contractors using compatible local components.
