Introduction
This booklet pertains to the North American, 120-Volt, version of the Quest roasters. A version is also
available for 220-Volt mains; we’ve made mention of the differences where practicable. There are only
two models, the M6, the M3, and a sub-model, the M3s. Moreover, they are all based on the same
platform. So, this handbook was conceived as “seen one Quest, seen them all.” But that isn’t true. The
Quest roasters are all hand-built, with many changes made and innovations added over the years.
Therefore, this handbook is of necessity not necessarily definitive for any particular roaster.
We’ve tried to include all the information found in the information sheets that come with Quest
roasters.
The temperatures herein are in degrees Celsius (see Annex for a Celsius to Fahrenheit conversion
table)
.
The Quest roasters are small versions of a commercial drum roaster. They can continuously roast back-
to-back batches with no cooling cycles required between roasts using a standard 120-Volt, 15-Ampere
electrical outlet. The original version (M3) and its successor (M3-Mk-2) were predominantly
conduction roasters. The current versions (M3s) and (M6) are hybrid conduction/convection roasters.
The operation of Quest roasters is manual. They have only three controls, an on/off/timer switch, a
heater power control, and a blower speed control. There is no proprietary hardware and no software.
They are easy to take apart using standard metric hand tools for cleaning, repair or modification.
There are no monitoring provisions beyond an ammeter that displays the heater current, a sight-glass
through which to view the roast, a trier, and ports for probes, if installed, to monitor bean temperature
(BT) and environmental temperature (ET). The roasters come with one analogue thermometer, which
will fit into either port. Optional K-type thermocouples are available.
There is no inbuilt smoke suppression on any of the Quest roasters nor provision for venting to the
outside. However, due to the simple design, many owners have been able to add ventilation.
What one receives may vary depending upon the supplier. The M3 roaster comes in a standard package
from the factory or the Quest dealer in the United States, Coffee Shrub. At the time of writing, the M6
roaster sold by Coffee Shrub comes complete with a rectangular bean collection tray that will fit into
the cooling chamber (but which is too small to handle a full load) and an external fan-driven cooler
(which is more than adequate for a full load). An M6 purchased from the factory does not include the
rectangular bean collection tray nor the external fan set. These are options that the buyer must specify
upon ordering.
