In addition to quality, reliability and financial benefits, Twin Filters added value is in the manufacture of custom-built products. At the same time, outdoor air is being drawn through the opposite heat exchanger “cassette” bank, returning the previous stored energy to the space, or process. When more air is exhausted than supplied, the effectiveness will be higher. No Freeze / No Defrost or Bypass Dampers Needed: With our REVERSE FLOW® capabilities, we self defrost on every exhaust cycle. Durable wood burning smoker cookers and charcoal grills for patio, competition and restaurant use. Reverse flow smoker baffle plate. As air is exhausted from a building or process, our two positional damper (which is the only moving part) directs the flow of air through one of the banks of pure 1100 aluminum alloy plates whose surface area has been maximized to capture energy from the exhaust air stream. Because of our REVERSE FLOW® design, our units are self-cleaning and most applications do not require filters. When the unit Reverse Flows, the intake of outside air does not form a single directional pattern, and air is drawn into the unit from all different directions. Not all Reverse Flow Smokers are created equal! Oklahoma Joe's Highland & Longhorn Smoker Mods, Accessories & Parts. 48"long by 24" diameter reverse flow square fire box right. It sears and sizzles on a hot clean griddle, thus pure magic. warming cabinet! The overall performance of the heat exchanger will also be affected as to large a surface area is as detrimental to performance as is to small a surface area. This is due to the air volume left in the cassettes, interconnecting duct and damper housing when the damper changes position. Best of all, the griddle is made of welded metal. If you've tried to do the math and build your own smoker, you've no doubt struggled! The principle of our Twin Plate Reverse Flow filter is a proven technology in a wide range of applications and suitable for batch filtration and fluids with a high dirt load. Check it … On exposure to air an oxide forms immediately on our high-grade aluminum plates. By simply changing the timing phases on our single two-position damper, or stopping it completely, we can control the amount of unwanted moisture retention as in a swimming pool environment or recapture exhausted moisture in the colder months, returning it to your facility. It should be noted that this stale air should be thought of as building air that never left the space. The same can be said of the larger, orifice plate based, MM meter. Saved by Orrin Fitzgerald. Reverse flow smokers allow heat to be evenly distributed across the cooking chamber of your BBQ smoker. Discover (and save!) 500 gal propane tank! As you can see, an orifice plate can be assumed as a hole in plate(with tapered exit)(This is done to minimize frictional losses). Due to the modular design, this system is ideal for both new and retrofit applications. The main objective of this paper is to study the reverse flow beneath a submerged plate by surface wave action in finite water depth. The heat is used twice in our reverse flow system, and in a Lang BBQ Smoker, the reverse flow baffle plate is fat searing on an all- welded griddle, sizzling and searing food to perfection with flavor and moisture beyond compare. The unit has been tested to temperatures down to -40 below zero. In normal situations this phenomenon is welcome because when the outside temperature is low, a ventilating system with a large amount of outside air has a tendency to dry out a building. When placed outside, this problem will not occur. 24" by 46" sq. The reverse flow baffle plate has the role of searing fat. (+- 5%) with our .402 static pressure drop range. It is very easy to blow the candle out at a distance of six inches, but when we try to extinguish the flame by inhaling it out from that same six inches it’s all but impossible. Because of the depth of our cassette units, 38” in all, a gradual heat transfer takes place assuring even energy dissipation into the incoming air stream, making for an extremely consistent return air temperature. In the Reverse Flow model the contaminated fluid is pumped into the filter through the center column, then evenly distributed to the plates for filtration after which the clean fluid flows into the tank and out a drain. If a variable air volume application is not properly managed, uncontrolled exhaust air moisture will collect within the heat exchanger and freeze at cold outdoor conditions. This allows the meat to be bathed in the smoke and keeps direct heat off the meaty goodness. The contaminated fluid enters the vessel and flows through the filter media towards the central outlet, where it is discharged. We are also able to control the sensible output for a VAV system when total energy recovery is unwelcome. Reverse flow inside a parallel plate channel can be achieved by placing an obstruction at the entry. The reason for the range is dependent upon the final size of these three sections when constructed, the timing of the damper switch point, and air velocity. Because the system is built around the individual cassette module, we have the ability to tailor the provided energy recovery equipment specific to the appropriate need. Outdoor air is now drawn through the newly energized cassette bank where the captured energy is released, returning it to the incoming air stream. The drier the outside incoming air is, the greater the latent recovery will be. The capability to manage these flow changes will greatly affect the overall unit performance through extreme weather conditions. Our patented technology is both simple and extremely effective. gravity feed double pan smoker plans. The smoke coming from the firebox is directed by an additional baffle plate to the opposite side of the smoker and then drawn back across the cooking grill on its way to the chimney. For the reverse direction, these boundaries were simply swapped so that the flow went from right to left. The inlet and outlet holes to the pelton wheel chamber are much different in size, so function poorly in reverse. Lid Gasket & toggle Latch Kits, Baffle Tuning Plates, Charcoal Baskets, and oem replacement parts & modifications for Oklahoma Joe offset bbq smokers. It can be installed where other systems can’t because of our ability to work with unique space requirements. The supply and exhaust air is guided alternately through these aluminum cassettes. Ring Plate Series (Reverse Flow) Description. With the growing need by engineers designing an effective system to vary the required amount of outside air, we have patented a unique methodology that allows for the same heat exchanger to flow varying amounts of outside air while still maintaining our high effectiveness. Segment clamp bolted or hydraulic operated quick opening covers. In the Reverse Flow model the contaminated fluid is pumped into the filter through the center column, then evenly distributed to the plates for filtration after which the clean fluid flows into the tank and out a drain. big pappa bill's beast! Because of the depth of our cassette units, 38” in all, a gradual heat transfer takes place assuring an even energy dissipation into the incoming air stream, making for an extremely consistent return air temperature. What is an Reverse Flow Offset Smoker you ask, it basically has the firebox off to the side of cooking chamber with a steel baffle plate that keeps the direct heat off of the meat. First lets cover some basic definitions: Baffle Plate– a plate of solid steel usually one quarter of an inch or greater in thickness which not only controls the flow of smoke and heat through the cook chamber but also … This system greatly reduces the need to humidify during the colder months. The principle of Twin Plate Horizontal Filters is a technology that has proven itself in a wide range of applications throughout the years. Many traditional offset cookers use tuning plates to baffle the heat in a similar way, but you don't get the reverse draw with the stack in the traditional spot at the other end of the chamber. Especially if you want consistent results for years to come. Any number of these cassette modules are enclosed in a double walled, 16 gauge, galvanized steel enclosure with a full 2” of insulation. The plate in a reverse flow will heat up as the smoke passes under it giving you a more even heat through out the cooking area. Construction Ring Plate and Vogue fans have a galvanised steel fan impeller and ring. The face velocity of the exhaust stream through the cassette is 350 to 546 FPM dependent upon sizing. The oxidation process stops under normal conditions or is drastically reduced in hostile “process” applications. When the outside temperature is 14° F or lower, approximately 70% of the absolute moisture is returned. Effectiveness of Sensible Energy Recovery: The effectiveness of the system is 80% summer 90% winter (+/- 5%). The heat shield affect you get from the plate helps to cut down on hot spots inside … The plate inside a reverse flow smoker acks like a heat shield as well as a smoke shield. This enables applications in industrial facilities, commercial office buildings, institutional settings (schools, colleges/universities), wherever fresh air and cost consciousness are at a premium. It sizzles and sears your food while maintaining the flavor, juiciness, and moisture and as your meat is cooking, most of the fat comes out, leaving you with the tastiest smoked food. The plates are installed parallel to each other with a 4mm gap between. Interior and Double Walled Exterior Units. The Reverse Flow Horizontal Plate Filter combines the advantages of horizontal plate orientation with clean filter tank operation. The shapes of the plates are designed to create airflow with a high-energy transfer capacity. Reverse Flow Smoker Plans; Offset Smoker Plans; Pipe and Rolled Steel Smoker Plans; Propan Tank and other Tanks Smoker Plans; Oval Oil Tank Smoker Plans; Santa Maria Grill Plans; Call Me; Shop For Smoker Parts. The high-grade aluminum plates are assembled in modules with 63 corrugated plates per “cassette” and are secured with a stainless steel frame and storm louvers. Cooking at temps below 300 then no problems. In colder months, heated indoor conditioned exhaust air passes over our previously cooled plates, condensation forms due to the large temperature variances. With our stationary design, REVERSE FLOW® and special plate technology we are able to size our energy absorbing cassette units to greatly enhance our ability to recapture the waste energy. An inspection every 5 years is recommended for normal operating conditions and if needed the cassettes are easily removed and can be power washed with soap and water or other mild cleansing solutions. Furthermore in order to prevent an increasing crossover contamination, we advise to place the cassettes directly against the outside wall when the unit is situated inside a building or use our multiple damper configurations. Realistically there is range between 2% to 4% of potential cross contamination generated from the standard energy recovery unit. When the system Reverse Flows this moisture is recaptured and returned to the conditioned space. The present work is carried out to study the influence of (i) splitter plates behind the flat plate obstruction at the front end and (ii) splitter plates placed at the rear end of the channel in tandem with the obstruction at the front. Flow is from left to right and the inlet and outlet boundaries are set 3D upstream and downstream of the plate accordingly. At 6.6 feet per second a single directional high speed exhaust stream would make the issue of the supply air mixing with the just exhausted air difficult at best, as the one second delay of the changing damper would push stale air away from unit. It took years of building smokers and using them to perfect our system. Our unique design also allows for high temperature heat recovery (450°F) generated from manufacturing processes. "As the meat cooks" the fat renders out. We guarantee sensible recovery effectiveness of more than 80% summer, 90% winter. When the outside temperature is higher than approximately 51° F, there will be no return of absolute moisture. Less than a .402” pressure drop is achieved with our guaranteed efficiency rates, compared to a competing product’s four size fits all application methodology that has greatly varying efficiency ranges and pressure drops totally dependent upon the CFM flowing through it. The modular design, also with minimal pressure drop, allows ultimate flexibility as both a new installation packaged unit or a retrofit utilizing existing fans. When more air is supplied than exhausted, the effectiveness will be lower. Remember that you also have the ability to configure the direction of the cassette banks so they are facing opposite each other to further reduce any chances of unwelcome stale air return. This makes it like a hot plate and helps distribute the heat throughout the cooking chamber. The original reverse- flow, off-set firebox design with the heavy, 1/4-inch plate steel construction sears meat with goof-proof perfection. The effectiveness is related to the balance between supply air and exhaust air. Parts and Accessories for Charbroil Ok Joe Grills. The horizontal position assures uniform precoat and an even cake distribution, without the danger of the cake dropping or cracking. The boundary conditions used assumed fully-developed flow at the inlet and hydraulically smooth pipe walls. big bull's smokin' bbq machine square firebox right side. The aluminum oxide that forms is a corrosion resistant self-protecting coating. When you truly need the energy recovery we are there working without going to an expensive bypass or defrost mode. Build A Smoker Diy Smoker Bbq Pit Smoker Bbq Grill Homemade Smoker Plans Custom Bbq Smokers Custom Bbq Pits Pit Bbq Smoke Barbecue. Probably the biggest advantage to reverse flow is evening out the temperatures across the length/width of the pit. As our damper changes position, (standard cycle is 70 seconds) the entire system works in REVERSE FLOW®. With our stationary design, REVERSE FLOW®, and special plate technology we are able to oversize our energy absorbing cassette units to greatly enhance our ability to recapture the waste energy. All this is built upon a full structural steel base frame. It has two energy accumulating cassette banks; each cassette consisting of specially designed plates made of 1100 aluminum. A simple illustration of what we are referring to would be the basic act of blowing out a candle. The problem with reverse flows, as i found out after i built mine, was the radiant heat from the plate under the cooking grates. Parker Hannifin Manufacturing Netherlands (Process Filtration) B.V. The reverse flow smoker has the chimney mounted on the same side as the firebox. I've crisped a few briskets by running to hot, which my plate is 1/8" thick and way over kill, but i'm running 325-350°. All cake or solids remain in the cartridge bundle. The recovery units must be sized according to the capacity of the ventilating system. Due to the horizontal position of the filterplates the filtercake can be subjected to as many consecutive processes as required, such as washing, extraction or drying. Yu and Dong (2001) numerically obtained downward and upward jets at the end of the plate and observed the formation firebox right side, w/ warming cab, and cart. The standard for damper change is 70 seconds but is adjustable for different environments. Heating or cooling jackets / therm plates. With our stationary design, REVERSE FLOW®, and special plate technology we are able to oversize our energy absorbing cassette units to greatly enhance our ability to recapture the waste energy. When our damper is in a fixed position we are truly in a free cooling “Economizer” mode to take advantage of free outdoor air conditions. We have spent years perfecting our design process. A Reverse Flow Smoker is a smoker which utilizes a “Baffle Plate” that is welded in solid in the “Cook Chamber” to control the flow of smoke and heat. Lang BBQ Smokers are the #1 BBQ stick burner smoker cookers. Reverse Flow Horizontal Plate Filter Reverse Flow Horizontal Plate Filter (RFHPF) The flow path through the standard HPF is into the vessel until pressure becomes sufficient to drive the filtrate down through the medium, onto the surface of the bottom side of each plate, out through each plate’s center ring, and down through the column created by the set of stacked center rings.
