Cocoa Bean Cleaning & Classification

Cleaning and classification is the first step in cocoa processing, and involves inspecting and sorting beans to remove impurities.  Removal of items such as sticks, pulp, bags, spoiled beans, and other debris ensures that your product is safe for consumption. Consumer safety is a priority in any food production facility, which is why JAF Inox has designed its equipment with health and safety in mind.  All machine parts that handle product are constructed using AISI 304 stainless steel or food-grade plastic and are easy to clean.

Manual & Mechanical Classifer

Royal Duyvis Wiener’s cleaning and classification equipment helps you to select only the best beans for roasting.  JAF Inox offers a sorting table for manual classification, or mechanical and 3-stage classifiers for efficient sorting of larger volumes of beans.

Cocoa Bean Roasting

Cocoa Beans are roasted to further develop the chocolate’s true flavor. Roasting is all about finding the perfect balance between heat and time to release the full flavor of the cocoa beans.  Unlike coffee beans, which roast at very high temperatures, cocoa beans are more fragile and require lower temperature roasting. Some may be tempted This process also ensures that there is sufficient moisture removal so that the beans can be efficiently winnowed after roasting.

Cylindrical Batch Roaster

JAF Inox offers two types of roasters – a cylindrical batch roaster, and a spherical (ball) roaster – both of which are designed to provide you with full control of the roasting process. Set temperature and time, and store recipes advance your craftsmanship and bring out the desirable qualities of flavor beans. Temperatures can be set for consistency or modified for flexibility, and recipe control esures that you get consistent quality throughout batches.

The most valuable part of the cocoa bean is the cocoa nib, and the winnowing process is key to ensuring that removes the outer shell of the cocoa bean, as well as well as flat or broken beans from cocoa nibs. Winnowing yields cocoa ‘nib’, which can be ground into coarse liquor for further refining into chocolate.

Sequential Sieve Winnower

The principle of separation by winnowing depends on the difference in density between the nib and shell. The winnower takes roasted cocoa beans, which are fed into an adjustable feeder, and breaks them using a hammer mill. The resulting nibs are separated from the cracked shell with the aid of a vibratory sieve and variable suction.

Coarse Grinding / Pre-Grinding

Coarse (or pre-) grinding comes after winnowing and is the first step in the refining process. Nibs are ground until friction and heat reduces them to a thick paste known as ‘cocoa mass’ or ‘cocoa liquor’. This can be achieved using a Royal Duyvis Wiener Batch Knife Mill or Continuous Knife Mill.

Batch Knife & Continuous Knife Mill

JAF Inox offers options for either batch or continuous pre-grinding. The process begins when roasted nibs, along with other ingredients such as sugar and lecithin (oil or butter), are fed into the mill.  Blades then rotate and grind the mixture into a coarse, pumpable cocoa liquor, to be further refined using a 5-roll refiner.

Five Roll Refining

Further refining of chocolate liquor is essential to generate the fine, smooth texture associated with high quality chocolate.  Royal Duyvis Wiener offers 5-roll refiner technology to ensure optimal particle size and ideal rheological properties of the chocolate.

Five Roll Refiner

Roll-refiners are precision-made machines that consist of rolls mounted vertically. These rolls are slightly ‘crowned’ so that when the machine is working, the pressure exerted will ensure that a film of chocolate with even thickness is spread over the full roll surface.

Chocolate Conching

The conching process serves to homogenize chocolate and optimize flavor profile.  Royal Duyvis Wiener offers both single shaft and longitudinal conches, depending on customer preference.  Both machine options offer precise control over process time and temperature, and work effectively to enhance flavor, evaporate excess moisture and volatiles, and stabilize chocolate.

Single-Shaft Conches

The single shaft conche reduces moisture content of the chocolate batch while removing volatile and undesired flavors. The single shaft provides a good and permanent exchange of chocolate particles between the rotors to produce a chocolate with excellent rheological quality.

Chocolate Tempering

Proper tempering is essential in producing quality chocolate. Well-tempered chocolate has a higher melting point and increased shelf-life, as well as characteristics such as good ‘snap’ and glossy shine. JAF Inox offers several different options for tempering machinery, all designed to provide finished chocolate with these ideal characteristics.

Compact Batch Tempering Machine

JAF Inox’s Tempering Wheel offers the smallest footprint, with a capacity of 3 kg it is well-suited as a ‘tabletop’ machine for lab and culinary use.  For larger volumes, JAF Inox also offers a Compact Tempering Machine (8kg/batch or larger 50kg/batch option) and Flex Tempering Machine (30 kg/batch) which comes with a vibratory table, and can be accessorized with a Flex dropping tool or enrobing machine.
