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.

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
150kg Ball Roaster
Ball Roaster with Bean Cooler & Exhaust Cyclones
Cylindrical Batch Roaster - Closed
Cylindrical Batch Roaster - Open
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.
Spherical (Ball) Roaster Capacities:
60kg and 150kg
PLC with recipe storage
Gas heater 70kW
Material in contact with product in Stainless Steel
Optional bean cooler available
Optional elevators available to load and unload beans
Classic look and design makes an excellent factory centerpiece
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.

Cocoa Bean Nibs from 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
Batch Knife Mill
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.
Stainless Steel Construction
Mechanical safety switch to protect operator
Includes automatic feeder to roll refiner
Low energy consumption
Easy transfer from pre-grinder to 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.

Chocolate Flakes from 5 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.
|Refiner Size||Refiner Capacities|
|10 cm x 20cm||20 to 30 kg/hr|
|20cm x 50cm||80 to 120 kh/hr|
|20cm x 80cm||100 to 150 kg/hr|
Roll position regulated mechanically between first, third, fourth and fifth roll
Chiller system included to cool the rolls
Speed controlled by digital drive
Scraper on fifth roll with easy adjustment
Easy removal of scraper for cleaning
Superb particle size reduction and distribution
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 Conche
Single Shaft Conche connected with 5 Roll Refiner
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.
Stainless Steel Construction
Single Shaft with Thouet Traditional Design provides clockwise mixing and counter-clockwise conching with shear force
Natural exhaustion by open cover/lid (grill)
Longitudinal Conche - Sideview
Chocolate Conching in Longitudinal Conche
Our longitudinal conches feature the classic look and design of yesterday, consisting of a flat bed upon which heavy rollers, attached to robust steel arms, move backward and forward. Additionally, JAF Inox’s equipment can be customized with color and logo, to make an excellent focalpoint in any factory.

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.
