The Spectra 11 is the current model from Spectra. You can read a full review and see how it's different from the previous model.
In addition, if you are comparing any Spectra Melanger to a Santha Wet grinder (or melanger) you need to read this about BuyIndianKitchen:
The Spectra 11 used to refine your Chocolate (and nut butters). It will refine as little as 1 lb of chocolate up to about 9 lbs of chocolate. Once your cocoa beans have been passed through the Champion, this piece of equipment is used to reduce the grit from the sugar you will add. We have been experimenting, and have verified that if you get your nibs very clean, the Stone Melanger will also grind the nibs to liqueur, saving the Champion step. Personally I find it a bit tedious for a large batch because you can only add a few ounces at a time, but the choice is yours.
The Melanger has two 7.5# black granite “stone” rollers that rotates at 120 rpm on a granite slab and two scrapper arms. This creates tremendous shear and reduces the particles of sugar and cocoa to the smoothness we expect in modern chocolate, somewhere in the 10-20 micron range. Please read the Grinding section about how to use it and it’s limitations. Please note, the bowl is NOT dishwasher safe.
We are really pleased that Spectra has worked with us on this product, and continues to make improvements. All of the Melangers are supplied to run continuously and ventilated keep the motor cool.
There is a standard 1 year warranty for these units. Please see the complete Warranty for more details.
All prices include ground shipping (they are drop shipped from the manufacturer). Expedited shipping (Express, 3 Day , etc) is NOT applicable to Melangers if other items in your order are shipped faster than Ground. If you are offered ANY faster options in checkout they are a glitch and you should not choose them.
As delivery is made to many countries with different electrical plug standards, the standard 220v product may not suit your standard outlet and there may be instances when you may have to have the plug replaced to suit your conditions.
