Production Process
Transparent pathways from nature to ready-to-export. We ensure that every coconut charcoal briquette is produced with international quality standards for stable and clean combustion results.
01. Incoming Raw Materials Acceptance and Storage
CV Java Mandiri Indonesia has its own warehouses to keep incoming raw materials separated by labelling codes based on supplier sources (Sumatera, Sulawesi, and the local) area for each stacking of raw materials.
​
Checking Quality: A sampling of the incoming materials is performed based on company procedure, and after that, the samples through checked for ash content, Ash Colour, burning test, and moisture.
Checking Quantity: A manual scale checks the quantity of material or weight before storing it in the warehouse.
02. Screening Process by Rotary Selection Screen and Manual
The Company uses two screening processes: a manual selection and a rotary screen to filter incoming raw materials for Physical Dust Disposal from Coconut Shell Charcoal and sort the raw materials from impurities.
03.
Crushing
After sorting, the selected raw material was crushed into 2-3 mm. Then, the crushed material takes into woven bags.
04.
Mixing
The crushed coconut shell charcoal is mixed with tapioca flour (5% of the total weight of coconut shell charcoal) and water gradually.
05.
Blending
An extruder machine performs the blending process around twice to get a homogenous half-product. Then, before moulding, those products shall cool for a while.
06.
Molding & Cutting
The blended half product is moulded and cut according to the size requirement of the buyer.
07. Drying in Oven
Briquettes dried at 40oC - 65oC in a drying oven for around ±72 hours, depending on the product types, until the temperature returned to the initial temperature.
08. Colling & Weathering
All Final Products are taken out from the oven and put in the open and dry area until reaching ambient temperature, then inserted into temporary sacks and continue to cooling and weathering process. The process takes a minimum of 14 days in total before shipment. The company conducts temperature checks and records of post-production process/cooling and weathering process and the tine before the final packing, as advised by the auditor.
09. Final Inspection & Testing
The final inspection and testing process is the last in checking the quality of the product before packaging, both qualitative (Smoke, Drop Test, Ash Colour, Sparkling, Smell, And Burning Test) and quantitative (Ash Content, Moisture Content, and Weight Checking of the product) The final external inspection consists of a vanning inspection, proximate test, and selfheating test carried out by an independent surveyor. The Company applies retained samples, which represent every individual shipped container. The samples are stored for three months in the factory to anticipate complaint handling and re-testing.
10. Packing & Warehouse
The final product is packed in Master Box with an inner plastic box by a manual selection process. The Company checks the temperature of the post-production process before the final packing. The final packed product is kept in the finished goods storage, and when the stuffing is carried out, the Company requests a third party to conduct a vanning inspection during the stuffing to the container shipment.
