Looking to start or expand a coffee roastery? One important aspect to consider is energy requirements. Does your facility meet basic requirements for electrical, fuel, water, and compressed air? Determining these values early in the planning process will eliminate costly corrections during equipment installation and allow the machinery to operate efficiently. These values can also be used to forecast facility energy costs. BURNS will provide a General Arrangement Drawing with equipment utility requirements early in the planning process so facility owners can determine their own Industrial Coffee Roaster Energy Requirements and prepare the site accordingly.
BURNS will provide specific manufacturer electrical requirements for purchased equipment. This will allow facility owners to determine power requirements, circuit sizes, and distribution panels for entire system. Standard power requirement for BURNS roasters is 480 VAC / 60 Hz / 3 Phase. If alternate voltage or frequency is required, this must be known early in the planning stage so BURNS Engineers can accommodate into the design package. An electrical schematic is provided with equipment. Electrical connections must be installed in accordance with local codes or in the absence, the latest edition of the National Electrical Code.
What type of fuel will be used for roasting? Natural gas is standard for BURNS Roasters but can also operate with other fuels such as LPG (Liquified Petroleum Gas). If LPG is to be used, the heating value (calorific value) must be specified so the burner components can be properly sized. The gas supply line must be of the appropriate size adequate for the gas volume required by equipment. It cannot be emphasized enough that the sizing of the gas supply line must be properly sized to provide enough volume of fuel gas at the minimum pressure required. Insufficient volume of fuel will result in poor burner performance. Be sure to account for all building appliances supplied by the same incoming gas line.
BURNS Roasters require 1-psig minimum and 5-psig maximum natural gas pressure at the gas train inlet connection. Incoming gas pressure must be verified prior to operation. A pressure regulator may need to be supplied on the incoming line. Gas piping installation must conform to the applicable city, county, and/or federal codes or in the absence, NFPA 54 latest edition must be followed.
The BURNS Roaster has the ability to stop the bean roasting process by spraying water onto the coffee beans. This requires that the water pressure, flow, and quality must be adequate for the specified roaster. Consult with a Burns representative for specific roaster details.
Compressed Air Requirements
The last item on our list of Industrial Coffee Roaster Energy Requirements is Compressed Air. Compressed air is used for pneumatically operated components. A standard BURNS Roasting, Cooling, and Destoning System requires 60 psig and 4 cfm compressed air. Customers must take into account if their compressor and line sizes are adequate to operate all building pneumatic components.
