The KN-8828P-2 offers an automated 'set-and-forget' roasting solution, and is our recommended choice for users who prefer to program the roaster upfront, then sit back and let it take care of the rest as best as it can. The results are typically not quite as good as can be achieved with the KN-8828B but it doesn't have the steep learning curve either.

KN-8828P-2 at a glance...

An automated roasting solution which provides a very good roasted result.

  • 250-300g roast capacity
  • All programming is done before the roast commences for peace of mind during the roast
  • Nine memory locations for saving roast profiles
  • Very easy to edit, copy and paste existing programs

Limitations over other Models.
Limited program editing options once roast has commenced
No proportional heater control makes fine roast control very difficult if partial heater power is required (e.g. 50%)
Control system does not 'look ahead' which can lead to overshoot of setpoint and heater complete shut-off for 2-3 minutes while it recovers

Operation In Brief

Enter auto-eject time and temperature
Commence the roast
Adjust heater power and fan speed to build a profile as you roast
Eject the roast when ready
If desired, save the profile you created to a memory location
When you turn on the KN-8828B-2 you can roast in 'auto' mode or use one of three built-in memory locations. Once you have selected one you can enter what's called a 'target time' and 'target temperature'. We don't like the terms 'target' because it implies the controller is aiming for these settings which it isn't - these are simply points which, if reached, will cause the roast to be automatically ejected so we prefer to call them 'auto-eject' points. If you've got a roast profile well established you can use these if you wish but we prefer to set them to maximum (25 minutes and 220oC) so neither are ever reached and they don't interfere with our settings.

Having done that you press the Start button and the drum will commence pre-heating. Once the temperature in the drum reaches 75oC the controller will beep at you to advise you to add the beans to the drum. The control panel will now show time remaining, as well as current drum temperature, heater power setting and fan speed setting. You can cycle through these four settings and change any you wish at any point (on time and temperature you'll change the auto-eject points, not the current readings).

Safety Features

There are three safety warnings you may encounter during your roast which come into play when temperatures or temperature change rates may be too high:

If the drum temperature reaches 180oC within the first 8.5 minutes - the roast will continue but the control panel will beep at you and you must acknowledge this by pressing any button (other than eject) within 20 seconds or the roast will eject
Once the drum temperature reaches 210oC - the drum will keep rotating but the heater and fan will turn off while the control panel beeps at you. Again you have 20 seconds to push any button (other than eject) or the roast will eject
Once the drum temperature reaches 220oC the roast will eject. There is no override for this safety point
Completing A Roast

Once the roast is ready you can press the Eject button. The roasted beans will be ejected to the external cooling tray and cooled to ambient temperature within a few minutes. Once this has happened you must empty the chaff tray before commencing another roast, and will have the option to save the roast profile you created to a memory location.

Warranty / Repairs

All our coffee roasters are tested prior to shipment so we are confident they leave us in working order. A 12 month warranty applies on all Hottop roasters with the following conditions:

If you report a fault with your roaster to your retailer within 28 days of the date of shipment, the retailer will cover the cost of its return to us for inspection and the cost of freight back to you. If the unit is not faulty we reserve the right to request payment for the return postage prior to returning your roaster to you which they may pass on to you.
If you report a fault with your roaster to your retailer after 28 days of the date of shipment but within the warranty period, you are required to pay to ship the roaster back to us where we will inspect it, then we will pay to ship the roaster back to you.
If you report a fault with your roaster to your retailer outside the warranty period, you or the retailer need to pay shipping both ways.
Any components that we determine have failed in the course of normal use within the warranty period will be replaced at no parts or labour cost to you.
In the case of any repair, we reserve the right to charge a $49.50 (inc GST) inspection fee if:

a roaster under warranty does not test to be faulty or if the fault(s) are deemed to be outside the scope of the manufacturer's warranty (including, but not only: incorrect use, use outside the manufacturer's guidelines, the removal of any panel screws contrary to manufacturer's recommendations)
a roaster under warranty has been damaged by the user in a way which we believe has contributed to the occurrence of the fault
a repair quote chargable to the customer (e.g. an out-of-warranty unit or repairs outside the scope of the warranty) is quoted and not accepted by the customer
