Roasting with the Sonofresco Commercial Coffee Roaster allows you to offer a high quality product and display a truly unique feature to your customers. The Sonofresco coffee roaster is an automatic hot air roaster designed to evenly heat coffee beans in a roasting chamber, monitor the roasting process, roast to a desired “roast level”, and cool the roasted coffee beans all in a seventeen to twenty minute...
Depending on the degree of darkness of the roasted coffee and the type of green coffee bean, it should take between seventeen and twenty minutes to roast and cool two pounds of coffee. In a ten hour day, you can easily roast fifty five to sixty pounds of high quality coffee with just one of Sonofresco Coffee Roaster.
Installation and Accessories Before installing the coffee roaster, unpack the appliance and read the installation and operation manual. Locations For your Roaster - Basic Requirements We believe the roaster will prove most valuable to your business if its located where your customers can see it in operation. You may or may not be able to do that, but there are a few essential requirements for the installation of the roaster.

Venting options include placing the roaster under an existing ventilation hood such as in a commercial kitchen, venting directly into a steel vent pipe, or the Sonofresco vent hood. We recommend the dedicated vent hood shown in Figure 1. The vent hood will allow the roaster to be vented greater distances and will eliminate the possibility of back pressure and wind affecting the roaster associated with direct venting.
Page 9
The Sonofresco Vent Hood also incorporates a halogen light aimed at the roast chamber to highlight the roasting process. The basic hood installation is shown below.
It is important to know that not all green coffees are equal. While most green coffee will roast well in your roaster, some poorly processed coffees may not. Sonofresco maintains a good variety of excellent specialty grade green coffees that have been tested for suitability for your coffee roaster.
5. Filling The Roaster and Component Assembly Remove Roast Chamber/Chaff Collector Assembly Lift handle to raise smoke box assembly. (The smoke box will rise approximately 3/4”.) Remove roast chamber/chaff collector by lifting straight up and back. Caution: The roast chamber is able to with- stand much higher temperatures than the roaster is capable of producing.
Page 13
Assemble the Chaff Collector Chaff wall ends After adding the correct volume of beans to the roast chamber, assemble the chaff collector and place it on the roast chamber. The chaff wall ends seal to the chaff collector base and screen grooves to prevent air and chaff from escaping from the roaster.
6. Control Board Functions Roaster Controls: The roaster is controlled by an electronic control board that monitors the roasting process based on information provided by the temperature sensor (RTD) and allows the coffee to roast to a predetermined temperature based on the roast level setting selected by the user.
Page 15
The Sonofresco Advanced Definition Roasting Control Board can connect to an optional Sonofresco Roast Profile Development Software package via a blue Bluetooth enabled PC or MAC. Please contact Sonofresco regarding up- grade options for your roaster. By default, all six profiles contain the Sonofresco default ideal roast profile. General operation The Sonofresco Coffee Roaster Control Board is designed to operate independent of the Sonofresco Roast Profile Application.
7. The Roasting Process Once the start button is pushed, the roaster will start roasting automatically and the following will be ob- served during the process: The blower will immediately turn on and the beans will bounce (fluidize) around in the roast chamber. ...
8. Coffee Basics Coffee Descriptions: We recommend reviewing our Green Been Page at www.sonofresco.com for brief descriptions for each of our single origin and Sonofresco blended coffees. Please let us know if you require additional information. Roast Temperatures: It is important to understand that different varieties of green coffee beans, whether a single origin or blend, will roast differently from another at a given temperature.
9. Preparing for the Next Roast After the last roast is completed, the roaster components will need to be cleaned prior to starting the next roast to ensure that each roast will be consistent with the previous batches. The following is a de- scription of the fundamental operation and the maintenance required between roasts.

10. Detailed Chaff Screen Cleaning The chaff screen consists of a wire mesh screen held in place by an aluminum outer ring. The mesh screen is simply wires woven together to create a wire grid. Each of these wires collect chaff and oil from the beans during the roasting process and must be cleaned to allow air to flow freely.
11. Roast Chamber Maintenance It is important that the roast chamber be cleaned after every roast to prevent the build-up of oils on the glass surface as well as the bottom plate. Oil build-up is not only unsightly, it will also affect the roaster performance if the build-up becomes excessive.
12. Daily Maintenance Daily maintenance is important to keep the roaster operating and looking its best. A maintenance rou- tine at the end of every roasting day will allow the roaster to begin operation the next morning without delay. The daily maintenance includes: Clean the chaff collector assembly as you would between ...
Page 23
The two most important items to properly maintain are the screen and the temperature sensor. The Sonofresco coffee roaster incorporates an improved hard mounted stainless steel temperature sen- sor which allows for more robust cleaning methods. The sensor will accumulate oils during the course of roasting, it is important to remove these oils on a daily basis to prevent excessive build up that can degrade the performance of the roaster.

The roaster control board readout is a segmented single digit display, error codes are cycled to the dis- play in series as follows: An error code “...
