Available in Steam Power (Gas or Electric) and Enclosed Indirect-Fire (LP or NG)
The 4BBL Brewhouses are specifically designed for breweries with primarily onsite beer sales, or limited distribution.
– Fully insulated mash tun and brew kettle mounted on a modular, radius edge, and stainless steel under-frame, designed for easy and efficient installation in almost any structure
– Proprietary radius edge platform design that virtually eliminates trip hazards and gives the Portland Kettle Works Brewhouse one of the tightest footprints available on the market
– Stand-alone Hot Liquor Tank (HLT) that has twice the capacity of the brewhouse. Making daily double batching, clean-in-place (CIP), and keg washing all possible, while alleviating the costly delays created by waiting for hot water
– Flexible brew system configuration
– In-line design, where only the mash and kettle are accessible from the catwalk
– Available in a Triangular design, where all three brew tanks are accessible from the catwalk
– Mash tun designed to efficiently brew a wide variety of beers
– Grain out door is positioned at the optimal level for off-loading into standard 55-gallon drums, for easy and efficient clean up
With our 5BBL and 7BBL Brew Equipment, you will notice that your Portland Kettle Works brewhouse has valves and controls conveniently positioned in a thoroughly thought-out and ergonomically designed manifold, which is immediately adjacent to and within arms reach of the brewhouse electronics. This is in contrast to some competitive brewhouses with valves and electronics scattered aimlessly around the system, dead end piping runs and little apparent devotion to the process of craft brewing. The lack of redundancy, and bold innovations you will discover in our brewhouse reflect the attitudes and experience of the brewers that helped perfect them.
In the strictest sense of the meaning a calandria is a heating element used for evaporation. In brewing systems designed by Portland Kettle Works, the calandria is a heating element through which wort or water pass to be heated. Calandrias are only found on steam brewhouses.
External Calandria is standard equipment on all of our mash tuns. It allows the brewer to very precisely control the temperature of the mash bed by pumping wort through the External Calandria and heating it anywhere from zero to 20 (or more) degrees F. in a single pass. This craft system is unique and proprietary to Portland Kettle Works.
Internal Calandrias are found on all of our Boil Kettles and Hot Liquor Tanks. They add a powerful heating element to the brewers tool chest, and can be controlled very precisely by adjusting the amount of steam feeding into them.
Variable Frequency Drive
Variable Frequency Drive (VFD) units are an electronic speed control devices for motors. You can think of a VFD as a dimmer switch for any motor in your brewing system. Portland Kettle Works employs VFD’s on every motor in your system. Brewhouse pumps, Pumps on a Cart, Hot Liquor and Cold Liquor feed pumps, and Mixers, Rakes and Plough components are all equipped with VFD’s which allow their speed to be controlled very precisely.
The Variable Frequency Drive controls motor speed by limiting the Hz cycle to 3-phase motors, the lower the Hz the slower the motor runs. A quality VFD should allow for full torque at lower speeds, so power is not diminished, only the speed of the motor is reduced. The VFD’s used by Portland Kettle Works are compatible with single phase, 220 V, 3-phase 208-230 Volt and 3-phase 460 Volt electrical systems. We only need to know how you want it supplied.
Wedge Wire / V-Wire
Wedge Wire or V-Wire false bottoms represent the state-of-the-art in mash filtration technology for brew houses. Portland Kettle Works uses only true V-Wire false bottoms in all of our mash tuns. The principal behind the V-Wire is that there is a large surface area contacting the mash bed, while under the contact surface the filter is a triangle in cross section. The surface area away from the contact layer falls away very quickly, minimizing the risk of clogging the filtration screen, while allowing free flow of wort through the screen. Less efficient alternates to V-Wire are laser cut, drilled or punched plates of steel that reduce efficiency and do not employ the well-known advantages of V-Wire in your mash tun.
Conical Bottoms & Ultimate Drains
Conical Bottoms and Ultimate Drains are designs on all Portland Kettle Works brewery tanks. We have engineered a slight conical bottom on Mash Tuns, Boil Kettles, Hot Liquor and Cold Liquor Tanks, and Grants. Every one of these components is equipped with a center ultimate drain sized to accommodate rapid flush out and cleaning of the brew tank. Little differences in design like a conical bottom with ultimate drain define the difference between a great brew day and a struggle every day.
Certified Food Grade 304L Stainless Steel
Certified Food Grade 304L Stainless Steel, also known as A2 or 18/8 Stainless Steel is the Food Grade Sanitary Stainless component used in all Portland Kettle Works tanks. The steel is composed of 17.5 to 20% chromium and 8 to 11% nickel along with other compounds.
Interestingly the steel is comprised of not more than .08% Carbon. The material is generally non-magnetic, unless it has been highly machined. Its ease of use in forming operations and long-term stability make it the steel of preference for brewery equipment.
Clean In Place (CIP) refers to the ability to clean tanks semi-automatically without the need for hand cleaning. Portland Kettle Works has engineered CIP into all of its brew tanks so that the tanks and kettles of our systems essentially become something like a stand-alone dishwasher. The tools necessary for this operation to be carried out include hot water, a pump, an internal spray ball and cleaning chemicals.
Clean in Place systems save the brewer a huge amount of time and labor. Properly engineered CIP systems will efficiently and quickly sanitize your brewing system.
