Information As the water proportion and hardness of green beans
changes, the color of green beans changes. Input of exact color
information is the beginning of the accurate roasting. 1. Roasting
can be started only after the drum temperature reaches to the
preheat temperature which is set in the machine. For accurate
roasting, drums preheating temperature should be reset by seasons
and green beans storage temperature. 2. Basic components of new
program are green beans weight green beans category(color) roasted
coffee color. By the selection of this information, computer
calculates the basic values such as 1st and 2nd crack temperature
and display on the screen. You can make your own specific programs
just by modifying these values little by little. Just with
adjustment each temperature setting 1~2 , you can get distinctive
roasting result. 3. Green beans weight is the basic information to
set the 1st crack temperature. In auto-mode, you can roast 1kg and
1.2kg. If the weight is not exact, the roasting result may quite
different. In manual mode, you can roast from 100gr at rates of
100gr. 4. Bean Type is divided in 7 levels according to its color.
(dark green, green, light green, medium, light brown, brown, and
dark brown) As the category is selected by its color, computer in
the machine automatically calculates each crack temperature and
last temperature. 5. Roast color Select roasted bean color among
light, medium, dark and pitch dark, and computer calculates 1st and
2nd crack temperature and last temperature according to this color
information. Coffee beans roasted by PRO1 are with darker inside
color than surface compared to coffee beans roasted by other
machines. So it is not needed to roast in Pitch Dark color for
special purpose. 6. Exact Bean Type and Roast Color selection is
the basis for accurate roasting programming. Slide 10 10 Basic
Information on Operation For the safety, read below attention
points before installation. 1. Taking out the cooling basket. Grab
the knob on the front side of cooling slider and pull the cooling
slider forward. 2. Opening & Closing the Chaff Drawer Grab both
chaff drawer knobs with both hands, and turn to the
counterclockwise at once to open them. (Clockwise for Closing) 3.
Opening & Closing the Hopper Grab the knob under the hopper and
pull forward to open door. Hopper door is tightly fixed to the
machine to make smoke does not leak through the hopper door. If you
want smooth door opening and closing, loosen 4 bolts around hopper
using hexagon wrench. ========================= =================
If green beans are ready in the hopper during preheating, some
beans get hot and this may cause inaccurate roasting. Do not load
beans on the hopper until POUR BEANS message is displayed.

All temperature settings(Drum, Bean crack and last temperature) are
calculated by the computer and displayed on the screen based on the
accurate green bean color and roast color selection. These
temperature settings can be adjusted during each roasting step. In
case of Pitch Dark (PT DARK) roasting, a little smoke might be.
There are 4 kinds of Roast Colors(roasted coffee color), and the
color selection is pre-requisite for accurate roasting. Press after
Roast Color selection, and (*) is moved to Weight option. Lower the
temperature a little when you want dark roasting and a lot when you
want light roasting. Slide 17 17 Roast : As Roast Color is
selected, the basic temperature settings(1st crack temperature, 2nd
crack temperature, last temperature) are calculated by the
computer. These temperature settings also can be adjusted by user
during setting and roasting. In case you set the new temperature,
use buttons. The coffee roasting theory IMEX adapted is to measure
the bean temperature when crack sounds and decide the roasting
method upon the bean temperature change. Even though the bean
species is same, crack temperature is different depend on the
moisture and hardness of beans, preheating temperature, roasting
environment condition and storage temperature etc. Just with the
proper crack temperature and time setting, you can roast your own
specific tasted beans. Generally high crack temperature setting
makes coffee with good body taste(oily) and low crack temperature
setting makes coffee with clean taste. 1st crack : 1st crack
temperature(ex.178 ) is set taking in a consideration of the time
from 1st crack(ex.175 ), and this tip can be your roasting secret.
Press buttons and set 1st crack temperature. 2nd crack : 2nd crack
is the bean temperature after making it lower after 1st crack.
Proper 2nd crack temperature is 10~12 higher than 1st crack
temperature. Set the 2nd crack temperature using buttons. Remark
Remark Press after Roast Color selection to change screen to Save
Mode. 6. New Setting Mode Bean Temperature Mode Last bean
