Cocoa Shell Pellet Mill

Brief Introduction

The cocoa shell pellet mill is a specialized biomass pelletizing equipment developed specifically for the characteristics of cocoa shells: thin, flexible, lightweight, fluffy, and difficult to compact. Cocoa shells are relatively light and have fine, soft fibers, which can lead to problems such as feeding bridging, loose pellets, and low output in ordinary pellet mills. The cocoa shell pellet mill addresses these issues by optimizing the feeding structure, finely adjusting the die compression ratio, and incorporating a flexible rolling system to specifically meet the pelletizing requirements of cocoa shell materials. This mill can process waste cocoa shells and cocoa peels from food processing plants into high-density, easily stored, and highly utilized biomass pellets in batches. The equipment is stable in operation, has low energy consumption, and is highly adaptable, making it ideal for cocoa processing enterprises, agricultural and forestry solid waste recycling plants, and biomass fuel processing plants.

Working Principle

The cocoa shell pellet mill employs a purely physical, flexible, high-pressure extrusion molding process, requiring no adhesives throughout. After simple crushing and moisture conditioning, the cocoa shell raw material is fed into the pellet mill's forming chamber. The equipment uses a multi-stage, uniform-speed rolling structure to comb, compact, and polymerize the lightweight cocoa shell fibers. Utilizing the inherent interwoven fibers and lignin properties of the cocoa shell, the material solidifies and forms under high-pressure friction. The material is evenly extruded through precision die holes, automatically cut to length by a cutter, and cooled to form compact, regular cocoa shell pellets. The entire process is automated, resulting in a high forming rate and zero material waste.

Suitable Raw Materials

TThe cocoa shell pellet mill is designed to process various waste cocoa shells, cocoa peels, and cocoa processing scraps. It is also compatible with lightweight, fluffy biomass raw materials such as rice husks, peanut shells, finely chopped straw, sawdust, and fruit shells. Raw material moisture content of 12%–20% is sufficient for direct production; material pretreatment is simple, and deep crushing is unnecessary before pelletizing.

Application Areas

Cocoa shell pellet mill produce cocoa shell pellets that burn without smoke, have a stable calorific value, and are considered clean biomass fuel. These pellets can be used for industrial boiler heating, factory heating, and biomass heat energy utilization. Cocoa shell pellets can also be used as horticultural organic substrates and organic fertilizer additives, achieving green recycling of waste. Simultaneously, they completely solve the problems of accumulated fruit peels and shells, waste pollution, and high processing costs in cocoa processing plants, effectively realizing the resource-based recycling of agricultural, forestry, and food waste.

Details

1. HUIXIN Gearbox: Heavy-duty HUIXIN gearbox provides adaptive torque to cope with variable extrusion resistance of grease-containing cocoa shell particles.

2. Rotating bracket: Reinforced rotating bracket suppresses vibration caused by uneven granular cocoa shell feeding.

3. Reducer: Precision matched reducer guarantees stable power transmission under long-cycle operation with oily shell material.

4. 304 stainless steel dust cover: 304 stainless steel dust housing resists oil adhesion, fine dust abrasion and mild corrosion.

5. Internal lifting knife: Built-in internal lifting knife breaks compacted shell piles and prevents sticky material bridging inside the pelletizing cavity.

6. Adjustable blades: Adjustable blades control feed thickness specially for fine cocoa shell particles to keep stable throughput.

Unique Advantages

1. Mill assembly: Modified ring die and roller set with anti-stick and wear-resistant treatment, tailored for oily cocoa shell instead of ordinary wood material.

2. HUIXIN gearbox: Reinforced HUIXIN heavy-duty gearbox with excellent heat dissipation, stable against torque fluctuation during continuous cocoa shell production.

3. Stainless dust cover: Integrated 304 stainless dust shield instead of painted carbon steel, not easy to stick greasy cocoa shell powder.

4. Bottom feeding reducer: Optimized under-feed reducer prevents cocoa shell particles from compacting and sticking at the feed inlet.

5. Cooling system: Directional circulating air cooling removes residual heat and surface grease stickiness, lowers pellet breakage and adhesion rate.
