This is a very rugged cast iron roasting frame and roasting contact clearances with the machine.  It is just plain solid and does not move under long or extended use.  Double wall drum means that the heat is all designed to go through the center of the roasting chamber, not "onto" the drum exterior.  Total true convection.  Not only is this the same style from the old Gothot & Barth Roaster days, but even better as the shaft design so that bearings are externally mounted and additionally are air cooled for long life and trouble-free control.  Even the side panels or product flights have a longer curve positioning more product flow into the hot air stream resulting in a slightly more rapid roast with more even bean interior and expansion that frankly leads the industry.  Bottom line is this roaster simply is quieter than anything on the market. Thermal insulation with the highest quality of fiber for low gas consumption and digital temperature control.  The cyclone is separate.  The cooler, being totally separate, also has the largest air collection area of any roaster made allowing for total ambient cool coffee in 3-4 minutes or less.  Add to this package a loader or your choice of destoners and even your choice of control methods. . . See below for details.

Note: a detail floor plan of your space allows Joper to issue location and space drawings specific to your installation during the official quote listing of all options and construction estimates at the same time.

Information about the Profile Roast Control

Using a roasted lot, or other previously created and stored in the BRIGUS data base, it is possible to define a new profile.  BRIGUS offers all the information: green coffee beans, weight of green bean to be roasted, stored information and a graphic with bean temperature profile lines, burner power (gas valve) and fan speed (air flow). Each line has 10 anchor points. By dragging and dropping these points, you can draw desired profiles.

When roasting in manual or automated mode, BRIGUS will register bean temperature information, burner level and fan speed, each second. Consequently, when that roast is called from the data base in order to create a profile, BRIGUS designs the curves similar to the real ones, being able to be manipulated in order to fit.

 The roast master does not need unnecessary parameters such as PID controllers (Proportional Integral Derivative) or others, in order to calculate deviation or error within a measured value and the value you which to obtain in order to produce a correcting action that will adjust the process.

Choose a desired profile for your roast. The chart will show dashed lines for bean temperature, burner and fan. After the roast is started, the solid lines evaluate, allowing the verification of the evolution of the roast process second to second. At any moment, it is possible to select what (burner and/or air flow) control in manual or automated mode.

Before, during or afterwards roasting, important information as green beans type and lot, environmental conditions, events (instantaneous and related to bean temperature), notes (free text), roasted coffee definition and color, can be introduced.

All information from each roast and their profiles will keep be kept in the BRIGUS data base, which allows a detailed analysis of the roast process, lot by lot or by comparing lots. BRIGUS helps understand coffee, eliminating unpredictable results and producing the desired cup.
The standard color is black with silver but you can customize it to your hearts content using the colors below. When selecting the color for your Roaster Body these RAL colors are all available.   Your local automotive paint shop will also have examples of the same. Choose and it will be done!  There is a small charge for custom RAL paint colors.
