Please download our maintenance list then follow procedures.
In the beginning of a roasting day, the machine is totally cold and needs to be heated up. PRE-HEAT option automatically heats your machine up and keeps the temperature on a certain level for a time period, so that the heat is equally distributed on your machine.
In order to run PRE-HEAT; open the main roasting screen, click on “PRE-HEAT” and then enter your target temperature.
At the end of a roasting day, the machine is hot and needs to be cooled down (Drum must rotate while cooling down, otherwise the drum may be damaged due to heat). END-DAY option automatically cools your machine down and you may end your roasting day faster.
In order to run END-DAY; go to main roasting screen and just click on “END-DAY”.

Buzzer is a temperature warning system that starts in various conditions.
For Manual Machines, there is 1 case that the buzzer starts to work:
– 2 Celsius degrees before reaching up to the safety temperature that is defined in settings (Default safety temperature is 350 Celsius degrees)
Buzzer is a temperature warning system that starts in various conditions.
For Automatic Machines, there are 3 cases that the buzzer starts to work :
– PRE-HEAT : When temperature reaches to target temperature defined while running the PRE-HEAT mode.
– PRE-HEAT : When waiting period at the target temperature finishes. (When counter is off)
– PROFILE REPEATING : When you make an automatic roast with a saved profile, buzzer starts 10 Celcius degrees below the final temperature of the saved profile.
NOTE : Buzzer starting range may be adjusted on Settings screen
Buzzer is a temperature warning system that starts in various conditions.
For Full-Automatic Machines, there are 5 cases that the buzzer starts to work :
– DRUM DOOR : When Drum door is opened.
– HOPPER DOOR : When Hopper door is opened.
– PRE-HEAT : When temperature reaches to target temperature defined while running the PRE-HEAT mode.
– PRE-HEAT : When waiting period at the target temperature finishes. (When counter is off)
– PROFILE REPEATING : When you make an automatic roast with a saved profile, buzzer starts 10 Celcius degrees below the final temperature of the saved profile.

There may be various reasons for the burner fault. Please check the following respectively:
– Check the gas supply. There may be no gas in the line/bottle
– Check the gas pressure. Gas pressure may be out of the recommended limits.
– Check electrical supply and the grounding. In order to work, machine must be grounded properly.
– If you have a monophase (220V) machine, switch your plug direction (Change the matching of socket holes and plug forks)

– Make sure your computer drivers are up to date.
– Make sure the correct connection is made from machine to computer.
– Change the cable which is using connect computer to machine.
– Make sure you select the correct machine type.
– Configure your computer Static IP adress. Static IP adjustment description file is available in the ‘Documents’ area. (Only Automatic and Full Automatic)
– Check the drawer, if it is full clean it up.
– Check the chaff collector, if it is full clean it up
– Check the pipe which is connect the cyclone to drum, if it is full clean it up

Yes, the incoming gas quality and pressure fluctuation can affect your roast results. Because, these factors are able to change burner’s efficiency and power output.
Therefore, control the gas pressure before your first roast of the day.
J type and 3 mm diameter thermocouples are used in the Besca machines
Yes, if the drum’s rpm is not calibrated in recommended range,coffee beans will rest against the drum wall too long during each cycle of the drum which increases the risk of the tipping and scorching

The time from the starting of the first crack until the end of a roast batch.
A curve representing the change in the bean temperature per unit of time during coffee roasting on the other words the derivative of the bean temperature respect to time
The period of the time over which data points are averaged to create an ROR curve ( Besca’s automatic and full automatic machine have Delta Span settings, the users can change it from the software settings)
Weight loss calculation provide immediate feedback about roast development and consistency. The %weight loss formula is shown below.
((Green Weight – Roasted Weight) / Green Weight)x100 = %Weight Loss
To make sure that the thermocouple measures the temperature correctly, heat a glass of water until it boil (100 C) then immerge the thermocouple inside the glass and check the temperature display of the machine. If the value correct, there is no problem on thermocouple. In case of opposite scenario, firstly clean the thermocouple with wet fabric and try to measure to the hot water temperature again. If the problem still exist, get in touch with Besca Roasters technical support team via “Help Desk (Ticket”).
The function of the destoner is to separate and collect foreign objects that may be in the roasted coffee.
Use only High Temperature Food Grade Grease (The grease should be resistant minimum 200 C). Hardware store or automotive types of grease can be toxic and are not to be used in the proximity of food products.
