21 Feb SIEBENSTER 30 kg Coffee Roaster Installation in Jeonju
We installed a large SIEBENSTER 30 kg roaster in Jeonju.
After the first inquiry call, they said they wanted to test the machine, so the company’s CEO came to visit with two staff members, three people in total.
Since they had traveled a long way to get here, we hoped for good results so that the trip would not be in vain.
Well, in large machines our value for money is already in a league of its own, so we were confident, and as expected, we signed the contract on the very day of the test.
The client company’s CEO wanted to purchase three units in total.
A 30 kg roaster, a destoner, and a 1 kg roaster.
After some time had passed, the products arrived in Korea. Because the large and small machines are made at different factories, we decided to install the three 30 kg machines first.
So today we installed only the three large machines.
Jeonju is quite far from Paju, so we arrived around 3 p.m., and by the time all the installation was finished, it was night~
Worth all the long hours of hard work, it looks great and performs well.
It is late, but we still have to run the testing, don’t we?
Roasting goes extremely well.
Although it is a 30 kg manual machine, it packs a great many features as standard.
Listing just the standard options, they are as follows.
- Two inverters let you control the drum and cyclone speeds.
This is extremely important in roasting. The nuances of a roast change completely depending on convection and conduction.
- An airflow pressure gauge is installed.
As a standard option, you can choose either an airflow pressure gauge or a cyclone thermometer.
In my personal opinion, the airflow pressure gauge is useful when roasting different batch sizes.
Generally, the more coffee you load, the weaker the exhaust airflow pressure becomes, because the amount of green coffee acts as resistance to convection.
Therefore, by checking the gauge reading, you can match the level of convective heat when you need to roast different quantities.
- Auto time-off function
Normally, after roasting is finished, you wait for the machine to cool down to a certain temperature before shutting it down.
Because of this, leaving work is sometimes delayed.
SIEBENSTER provides the auto time-off function as standard on both manual and automatic models.
Fully automatic machines use a PLC, so they can be linked with the thermometer and shut down based on temperature; on manual machines this is difficult, so we currently use a timer. The machine shuts down automatically after a set time, so you can head home with confidence.
- Safety features
In SIEBENSTER roasters, the gas and electrical systems are separated.
Every spark is a potential ignition source, so it is best to keep sparks as far away from the gas as possible.
Design-level safety is a given, and several additional safety devices are provided.
First, the gas is automatically shut off if either the drum or the cyclone is not running.
Second, a flame rod is used, so the gas is automatically shut off if normal ignition does not occur.
If gas kept leaking without ignition having taken place, that would be a serious problem, wouldn’t it?
You may say, ‘Are there really machines like that?’ But… quite a few exist. Be sure to check.
- Changing the number of outlets for destoner use, or a rotating-cooler function
The machine installed this time was built with 3 coolers. Depending on requirements, however, we may also build it so that the cooler discharge direction itself can be rotated.
Because everything is built to order, we accommodate the customer’s requirements as far as possible and do not charge extra.
- Timer and roasting light
You might think, ‘Is that really an option?’ But… many machines have neither of these~
Of course, both are included as standard options.
The standard options are pretty impressive, aren’t they?
Then I should briefly explain the paid options too, shouldn’t I?
There is exactly one paid option.
.
- Full automation!
Everything else is completely free.
After the long installation and testing, I took one farewell shot as I left the factory.
May you hit it big with a SIEBENSTER roaster!
