Re: Solar Autoroast and Torrefattore 2kg discussion thread

Hey Chris,
Any more news about the Torrefatore? Delivery date, finalised cooling design, expected price?

Re: Solar Autoroast and Torrefattore 2kg discussion thread

Hi,

New model Torrefattore 2kg is in production and I expect out orders arent too far of completion. I dont have the final pics yet as they are on a couple of weeks leave with Italian holidays.

All I can say at this point is that they have used a 6inch flat blower for the outer cooling design. It will be very good as expected. The initial machines will be at a launch special for CS members significantly under what they will retail for which will be in line with the Solar 2kg RRP.

I am just holding off the final specs and taking orders until I have the pics as I know if I dont questions will follow that I may not be able to answer. If the initial interest is good and dollar stays strong we may extend the special price so as to be fair to everyone that has already put their names down with myself, Chris or Den. Coffee Craft in Adelaide will also be retailing them.

Cheers, Mark

Re: Solar Autoroast and Torrefattore 2kg discussion thread

Hi guys,

New pics of the Torrefattore 2kg Manual.

6inch blower has been used for the in drum cooling option instead of the 4inch in the Solar (sorry I mentioned for outer in the above but got confused over the information supplied to me). Outer cooling is also included. I have been told the in drum should cool within 5 minutes with the bigger blower or you can drop earlier to the outside cooling unit if wanting to drop another roast.

Manual airflow control as well as option to program the airflow automatically (time and pulse intervals)

PID controller for accurate temp control and stability as well as control over the elements. To enable more subtle temp application (slower roasting) if required.

Bean sampler included.

Introductory offer to CS member is: $9990 inc GST after which the price will move to in line with the Solar 2kg at $11,990 inc GST. We are expecting stock in about 4-5 weeks and will be taking orders now. So far we have 4 units on there way in the initial batch but will extend the offer if we get orders for more than these 4 by the time they get here. We understand that purchasing or placing a deposit on the machines without seeing them in action bares a risk so to alleviate your concerns here anyone placing initial orders will have a 14 days returns policy should they not be happy with the equipment after they receive it. Full 12 month warranty is provided will all spare parts stocked locally.

You can contact myself at Coffee Roasters Australia, Talk Coffee or Cuppacoffee to place orders or contact myself for any questions you may have on sales@coffeeroasters.com.au.

Cheers, Mark

Great looking machine and a nice offer...

Now if any one trades in their old 1kg machine I might be..... Say again; just might be in a position to consider it

Hi Mark,

can you just clarify that is a conventional sampler to the right of the door? Also does the door have a clear panel as well?

Yes and yes to both these questions.

Re: Solar Autoroast and Torrefattore 2kg discussion thread

Few more questions.
Did the external cooling get upgraded?
Is the idea to reset the PID during course of roast to adjust profile or just to set target/finish temp?
PID works off bean mass or enviro sensor?
Would an additional temp monitoring probe be able to be fitted easily?

Re: Solar Autoroast and Torrefattore 2kg discussion thread

Did the external cooling get upgraded?

No, they upgraded the internal cooling as otherwise they would have needed an additional motor and exhaust vent making the design different and adding to the cost of the unit in production (and exceeding cost of the Solar). This way the cost can be kept lower as the chassis design can be mass produced for use with the Solar as well. You can complete cooling in either the drum or external...the drum has the advantage of clearing the smoke and chaff from the finished roast and ideal agitation. I dont think the cooling is going to be a problem...it doesnt effect the quality in the Solar so I doubt it will in this too. You have a 6 inch blower vs 4 inch so a fair bit more power there. I demo and roast on the Solar all the time and cooling has never been a problem for me with quality of roast, the outer cooling actually finishes it off quite quick and it roasts very evenly.

Is the idea to reset the PID during course of roast to adjust profile or just to set target/finish temp?

You need to adjust the PID during the roast as you would adjust a commercial roasters gas flame or temp controller. It is not like the Solar.

PID works off bean mass or enviro sensor?

More so enviro sensor as you are controlling the heat in the drum. Trying to control heat via a bean sensor is not ideal as it doesnt give you a good indication of what heat you are applying to the bean and is not as reactive as beans hold their thermal energy. If we set up roasters for temp control automation of the burners we prefer to use the enviroment in the drum as the source. Bean temp is more a guide for profiling smoother curves, indicating changing temps of the beans and points like 1st crack/2nd crack, stalling etc but doesnt let you know what temp is being applied to the beans. For example you can cut the heat off and a bean probe will probably still climb or hold after yellow for a while even though you have dramatically reduced the temp of the environment.

Would an additional temp monitoring probe be able to be fitted easily?

Yes...CS profiler can easily be fitted. We can do that prior to delivery if you wish. It would be a good addition to the unit and would enable computer profiling. We would do for $100 inc GST extra, fitting and supplying the datalogger. Otherwise if you already have a CS logger we could pre drill and tap the hole prior to delivery.

Hope this helps...cheers

Re: Solar Autoroast and Torrefattore 2kg discussion thread

in regards to the drum cooling

do you have to use it at all?

can you just dump beans to external cooling, and then cool drum empty for next roast (if you need to cool it)?

or is it a "have to use drum bean cooling" style thing?

these are neewb questions..... and was a bit confused on the cooling of the beans as i was concerned that dumping the beans out may have a detrimental effect on the roaster?

Re: Solar Autoroast and Torrefattore 2kg discussion thread

No it doesnt have to be used but will cool a lot quicker and take the initial smoke and remaining chaff away if you start cooling inside. You also have the good agitation in the drum but you can cool inside for a couple of minutes then drop outside to finish them off while you start the next roast. The machines get up to temp very quick so there is not a lot of waiting around and with the manual control you can easilly manage various roast times to suit your style or what you want to achieve. As the drum is perferated the chamber temp is reached quicker so you dont have the same times required for heating sealed drums and consistency difficulties between you 1st roast of the day and the next.

One of the huge advantages is that you can have individual roast profile settings for the airflow, program it in and you get the consistent air application each time (you can also run manual via the air switch as well if you want). You have such great control over differnt applications of heat to the roast via conductive, convective or radiant. Its, one of the advantages of using a blower vs neumatic air application and being electric as it gets around all the gas laws in relation to having to have some airflow while the gas burners are on for certification standards. Plus you dont have all the other additional costs for gas installation and approvals. You can even use the blower and heat to roast like fluid bed if you want. I dont know of any machine that you would be able to do all this.

Re: Solar Autoroast and Torrefattore 2kg discussion thread

I couldnt find any pics or info on coffee-techs website or google.
Have these machines been released elsewhere yet?

Not yet off the production line from what I understand. The best shots or info I have found anywhere is what Mark has mentioned or posted here.

Re: Solar Autoroast and Torrefattore 2kg discussion thread

Can any one give me feedback/review on Solar automatic 2kg roaster? What are the good points and bad? I know there is less control on profiles, having this limitation does it roast a good coffee with both hard and medium beans. My understanding is you only have control over temp. Does this greatly reduce the quality of the roast?

Thanks Chris

Look up Chris ^^^^^^^^^^^^^^

The search tab would have returned a heap of hits and saved creating a new thread too. Why not give it a shot?

Sounds like the Torrefactore 2kg might suit you.
