Product Description

Spectra 70NB Stone Grinder - Chocolate Melanger | Cocoa Melanger | Cocoa Grinder | Chocolate Grinder | Nut Butter Grinder

The ideal Spectra 70NB Cocoa Melanger for cocoa processing and nut butter grinding processing and other multipurpose grinding needs. For long, a request from Chocolatiers had been the need for controlling the speed of the conching & refining process, and we listened. The newly developed stone cocoa grinder model with an electronic speed controller unit allows the drum rotation speed to be varied from zero to full speed, and at the same time also allows for the unit to be used worldwide. This 20 kgs capacity commercial chocolate grinder machine is the perfect companion to an enterprise. The classic Titling feature makes it unnecessary to have to lift the vessel or drum to pour out the contents. Simply tilt and pout it out and avoid straining yourself. Cleaning is a breeze..... simply pour water, run the stone grinder for a few seconds and pour out the water... it almost cleans itself. Solid Stainless Steel stand provides elegance, strength and durability. In addition, this cocoa melanger has all the features that make it stand out ... powerful motor, black granite stone for long life of 10 years or more and high quality internal and external components.

Tension of the granite stones can be adjusted to obtain different grades of shear at different stages of grinding and for different ingredients. Double granite roller stones that rotate over a granite base. This creates tremendous shear that reduces the cocoa nibs to fine chocolate liquor with a particle size of the order of less than 15 microns.

Spectra 70NB Cocoa Melanger with Speed Controller and Control Panel

Speed controller and control panel is provided as standard with the unit, and comes with built in electrical MCB protection. This unit helps you to set the chocolate melanger speed for different processing and adjust the quantity of ingredients. This is very much useful for you to differentiate your process from others, and make your recipe and processing unique to yourself.

The Spectra cocoa grinder machine works as a chocolate conching refining machine. The tension from the stones can be fully released for the conching cycle without grinding further, such that the cocoa liquor is continuously exposed to air without grinding it further and the volatiles are removed. All models have this feature and there is no need for a separate model or attachments to buy. There is no need to buy any additional add-on's or attachments, and all are included.


We are excited to give you the option of selecting Belt or Chain drives for this model. The belt or chain drive machines are identical in all respects and cost the same for either option. The main difference is that the chain is slightly noisier like you can imagine a fast bicycle chain, while the belt is very quiet in operation. The belt needs to changed out every 1-2 years, and the chain needs replacing every 3-4 years. The chain also needs to be cleaned and lubricated every 2 months. Replacement costs for spare belts or chains is not expensive and both are economical. Please select your preferred option before adding to cart.

CE OPTION: This model is available with CE rating if required as an option.
