Máy rang cà phê Fresh Roast Sample Coffee Roaster SR800

The Fresh Roast SR800 is similar to the much-loved SR540 with increased chamber volume, advanced heater, improved internal electronics, and a heavy duty fan. What does that add up to? A larger, 8 oz batch size!
There is a single knob that controls heat, fan, and time - just push the knob to toggle between parameters. A quick turn of the knob to the right will display real-time temperature readings - no need to add a thermocouple to the roast chamber! There are now 9 levels of heat adjustment compared to having a Low, Medium, and High adjustment. We like the general design concept because it doesn't try to automate anything and allows direct user control.

The chaff collector works well and, although it doesn't have a smoke reducer, the top of the machine slows the flow of smoke so roasting under your oven's hood fan will eliminate most of the smoke. The stronger fan in the SR800 does a great job of agitating the beans and the new, wider roast chamber allows for a more even roast compared to the older SR500. Switching to "cool" in order to extend the roast is a good trick to help with roast control.
Please note: The chaff basket from earlier SR roasters will not fit on the new SR800 because the new roast chamber is much wider in diameter.

FreshRoast SR800 Tip Sheet
These tips are meant to supplement the Fresh Roast SR800 manual. Be sure to read the manual!
Use a stove hood or fan for ventilation. You can roast outdoors (in mild weather) or near a window, but cold temperatures can slow the roaster. Line voltage, extension cords, or power strips can also affect the amount of heat your roaster produces, so you may need to experiment.
Not letting the roaster cool to room temperature before starting will quicken a roast as well.
Never leave the room while you are roasting coffee, even when using an automated roaster.
The time between a dark roast and a fire is not as long as you think!
Batch Size: The manufacturer recommends using eight of the provided scoops. We found best results using 215g of beans, but you can roast up to 8oz (about 225g) per batch. We hit first crack about 6 minutes into the roast; City+ roast at about 8 minutes; second crack (Full City/Full City+) at about 10-12 minutes. Time is less important than color changes and listening for cracks.
Settings: Default settings are Fan 5, Heat 9, and Timer 6.0. We found best results come with keeping the heat on high (7-9) for the entire roast, and adjusting the fan speed for any profiling. We recommend resetting the default (directions in manual) to Fan 9, Heat 9, and Timer 20.
After the first 1-2 minutes of the roast, be sure to turn the fan speed down - if you keep the fan at 9, you may never reach first crack.
We recommend using a separate timer. The built-in countdown timer can be confusing.
Dry-process coffee has more chaff and raises roast temps, taking up to a minute off of your roast.
Pay attention to the process, especially towards the end of the roast as the FreshRoast brings coffee rapidly through the roast stages. Lock the roast chamber to the base unit! Even with the improved design, the 800 is tippy - be sure to remove the roast chamber and chaff collector before moving the roaster. Brush the chaff collector between roasts and soak it occasionally to remove built-up coffee oil. Oil left on the chamber is of no consequence unless it impedes visibility or becomes a fire hazard.
Wait a minimum of 4 to 24 hours after roasting before brewing. Coffee is best 3 to 5 days after roasting, and after 7 days starts to decline in flavor.
The newly designed roast chamber has a wider diameter and does a much better job of agitating the beans compared to earlier models. That said, try these techniques for a more even batch:
Green coffee is heavier than roasted coffee. Keeping the fan on high during the beginning will help to produce an even roast.
Small batches take longer to roast than large batches since a larger volume of beans traps more hot air. If your batch is too small, you may never reach first crack.
