Cocoa bean processing equipment includes a roasting machine, conveyor belt, cooling belt, peeling machine, elevator, roller classifier, etc. This production line can process cocoa beans into cocoa nibs, which are the raw materials of cocoa powder, chocolate, snack making. With the characteristics of a high degree of automation, simple operation, stable performance, and high product quality, the production line is an ideal choice for cocoa nibs processing.

Working flow of cocoa bean processing plant
This plant consists of roasting, cooling, peeling, classifying steps. The raw materials of this plant are fermented cocoa beans. After cocoa pods are picked from the trees, farmers need to use a cocoa pod cracking machine to break them. And the cocoa beans inside the shell are sticky. So these cocoa beans need to be fermented and sun-dried before further processing.
- Dimension: 4.5m×2.9m×1.75m
- Motor power: 5.5kw
- Electric furnace power: 112.5kw
- Output: 500kg/h
- Temperature: 0-300 degrees
The electric cocoa bean baking oven is a new type of high-efficiency and energy-saving roaster developed by Taizy Machinery based on the company’s many years of production experience. It mainly applies in the food processing industry, beans, nuts, such as peanuts, almonds, chestnuts, broad beans, etc. to reduce moisture to dry and roast cooked products.
This machine uses an electric heating tube as a heat source, adopts a rotary rolling cage, heat conduction, heat radiation principle, and is equipped with an automatic temperature control device. Use hot air as a drying medium, and apply heat energy to the raw materials. The roasted object is continuously advanced by the propelling device in the cage, forming an uninterrupted cycle, so that it is heated evenly, and the roasting quality is effectively guaranteed.
Conveyor belt before the rosting machine
The conveyor belt is fixed on the front of the toaster. So after cocoa beans are roasted, it can conveyors the beans into the cooling belt. During the baking process, there is no need to start the conveyor belt in front of the furnace. When the baking machine is discharged, it is opened in advance, and it can be closed after the conveying is completed. Long-term use will cause the bearings and chains to be short of oil. Appropriate addition of lubricating grease can reduce wear.
- Size: 10mx0.7mx1.5m
- Power: 1.5kw
- Speed: 14m/min
The conveyor belt adopts a square tube welded ladder-type bracket, which greatly enhances the carrying strength. It has a stainless steel mesh belt surface. Cooperating with baffle, it can realize lifting and conveying. It has the characteristics of small size and high conveying efficiency.
- Dimension: 13mx1.2mx2.6m
- Conveyor power: 1.5kw
- Cooling blower power: 0.55kwx6
- Cooling suction fan power: 2.2kwx4
The cooling zoon is connected to the conveyor belt in front of the furnace. The transmission motor adopts an electromagnetic speed-regulating motor. According to the discharging characteristics of intermittent baking, the material on the uniform mesh surface can be conveyed at a high speed, and then the temperature is quickly cooled down after a period of static. Finally, the material is slowly conveyed out with the speed of the subsequent peeling processing equipment.
The cooling belt adopts a square tube welded ladder-type bracket, which greatly enhances the carrying strength. The permeability of the stainless steel mesh belt surface, combined with the air blowing and negative pressure suction of multiple fans, makes the room temperature wind penetrate the material layer and carry away the residual heat of the material, resulting in effective cooling.
Note: For the electromagnetic speed control motor, the pointer of the governor must be restored to the zero position after the machine is turned off. So as it will not burn the governor when next time it is turned on.
Cocoa Bean Peeling Machine
- Power: 2.2kw
- Fan power: 2.2kw
- Output: 1000kg/h
- Size: 2mx1.1mx2.1m
This machine is the special equipment for peeling cocoa beans, peanuts, and other nuts. It has the advantages of a high degree of automation, high peeling rate, low noise, and no pollution, etc. The vacuum cleaner of this machine can suck off the peeled cocoa shell so that the separated cocoa nibs are uniform and beautiful. Less material consumption It is an ideal choice for the food processing industry.
The raw material is squeezed by three rubber rollers and divided in half by differential motion. During the vibration conveying process, the detached skins are separated by a low-pressure fan.
- Size: 2.6Mx0.88mx2.5m
- Power: 0.75kw
- Transport volume: 1000kg/h
The stainless steel screw elevator is composed of a hopper, a conveying tube, a screw auger, and a transmission motor, all made of stainless steel, suitable for granular and powdered food. The material in the hopper enters the bobbin through the inlet lower than the connection with the bobbin, and passes through the high-speed rotation of the spiral blades, and moves upward along the customs clearance to achieve the purpose of lifting.
Cocoa Bean Sorting and Grading Machine
- Size: 4mx0.8mx1.3m
- Diameter: 600mm
- Power: 0.75kw
- Output: 1000kg/h
The drum classifier is composed of a sieve bucket, a supporting device, a collecting hopper, a transmission device, and a frame. The meshes on the sieve barrel are arranged in order from small to large. The sieve bucket is inclined at a certain angle. When the sieve bucket rotates, the material rolls in the direction of the outlet. It can fall out through the appropriate sieve.
This classifying machine can also apply to cocoa nibs, peanuts, pine nuts, and other nuts.
The size and shape of the screen mesh can be determined according to the specific requirements of the user, and the materials are classified from small to large. It is suitable for grading round materials such as various nuts, mushrooms, horseshoes, grapes, etc. according to different sizes and specifications, and the grade is 4-5.
After the processing steps, cocoa beans could enter into the next cocoa powder production line or be packaged into bags.

Advantages of cocoa bean processing machines
- Simple automatic operation
These machines can connect to form an automatic production line, and workers can easily process cocoa beans.
- Large output
Every roasting oven can process roughly 100kg of raw materials per hour. And it usually connects 5 or more ovens to be a large roasting machine.
The cocoa nibs processed by this production line can be packed to sell or be the raw materials of cocoa powder making.
