|Electric Brewery Controller- Single Vessel [EBC-SV]|
At the heart of the EBC-SV controller is the ubiquitous Auber PID Temperature Controller. The Auber PID is a high precision controller with features that include 0.02% accuracy, enhanced fuzzy logic stability control and a bright LED display that is easy to see. Programming the temperature could not be any easier to do, just press the up or down arrow buttons to set the target temperature on the lower green LED display. The readout from the temperature probe is then displayed on the upper red LED display. Once setup the PID controller does the rest, it energizes the heating element inside the kettle as needed to accurately maintain the target temperature.
|The Auber PID Temperature Controller|
The EBC-SV comes in both 110 volt and 220 volt models, making it the perfect brewing solution for every home brewer. Whether you install a new 220 volt 30 amp circuit, or use an existing one, you will have enough power to brew 10 gallon batches with ease. Built from high quality, readily available components, you can expect this eBIAB system to provide you with years of reliable operation. The temperature controller display comes preset to display in degrees Fahrenheit and using the controller to accurately maintain mash temperature is simple. Just press the up and down buttons to set your target temperature, add your mash water to the kettle and then turn on the Chugger pump.
|Wort Going To Spray Nozzle And Temperature Probe|
The wort is pumped from the bottom of the kettle, where the electric heating element is located, up to the spray nozzle mounted underneath the kettle lid. The threaded end of the spray nozzle screws into a tee fitting where the temperature probe is mounted. As liquid flows around the probe on it's way to the spray nozzle, the temperature data is fed back to and monitored by the controller. The controller then energizes the heating element as needed in order to maintain the mash set point temperature.
|The Round Knob Is Used To Regulate The Power Going To The Heating Element|
The round knob on the side of the controller adjusts the power output to the heating element. When turned fully clockwise the heating element receives the most power, this setting is used to quickly raise the temperature of the liquid in the kettle. Once the liquid reaches a boil turning the knob counter clockwise reduces the amount of power sent to the heating element. To prevent boil overs it is a good practice to reduce the power to the heating element, by turning the knob counter-clockwise, until the wort maintains a steady rolling boil.
|Gravity Primed Chugger Pump Setup|
The Chugger pump is not self-priming, instead the pump uses gravity to prime itself, as long as the inlet to the pump is positioned lower than the kettle valve. The orientation of the pump head can be changed by removing the four screws that mount the front of the pump head to the pump body. With the screws removed, the pump head can then be rotated as needed to position the inlet below the center line of the pump. To use the pump open the kettle valve then turn on the pump switch, the pump will prime and begin pumping almost immediately.
|Disassembling And Cleaning The Pump Impeller Shaft|
Chugger pump impellers rotate around a stationary shaft that is mounted to the pump body. The design uses very close tolerances between the shaft and the impeller bushing, for both maximum performance and quiet operation. If too much sticky wort builds up between the shaft and the impeller, the impeller will bind on the shaft stopping the pump. The magnetic drive on the pump motor turns the impeller. The magnetism used is also strong enough to stop the motor from turning when the impeller binds to the shaft. More detailed instructions on how to disassemble and clean a stuck Chugger pump impeller can be found here.
|Cleaning The Heating Element Maximizes Efficiency And Life|
At the end of the brewday the kettle, tubing, pump, chiller and spray nozzle is easily cleaned by mixing a spoonful of Oxi-Clean Free in 2 gallons of water and heating it to 140F. Add the water to the kettle then mix in the Oxi-Clean Free and run the pump with the controller set point temperature set to 140F. Use a bristle brush and sponge to clean any heavier buildup from the kettle and then empty the kettle and repeat the process using clean water. It is important to remove all debris from the system before it has time to dry and to then flush the system with clean water until it runs clear. Thoroughly clean the system after each use, to prevent the pump impeller from sticking, and to make sure it is always ready to go.
|Clogged Shut Off Type Disconnect (On Right)|
The HFC 35 Polysulfide High Flow Quick Disconnects that shipped with the system are easy to use and make connection changes a snap. Unlike metal disconnects that transfer heat quickly after hot wort has been run through them, polysulfide disconnects will not burn your hand when changing connections. The HFC 35s are rated for safe operation with liquid temperatures up to 280F. Their large easy to press thumb latches make them perfect for use in brewing systems, especially when used with high quality 1/2" ID food grade silicone tubing.
|Replace Shut Off Connectors With Straight Thru Connectors|
The shut off type connectors that came with the system are prone to clogging whenever a large enough piece of grain enters the tubing. With brew in a bag brewing grain can escape through a hole in the grain bag and then get sucked up by the pump. Once enough grain gets lodged inside the shut off valve the tubing will become blocked and wort circulation will stop. Replacing the shut off type connectors with straight thru type connectors will prevent the connectors from becoming blocked. To eliminate any chance of blockage the connectors can be positioned so the interior cross bars are aligned, providing the largest open area inside the connectors.
