Making Charcoal Coconut Shell Briquettes Using High Pressure Machine

What is different between Conventional machine and High pressure Machine to make charcoal coconut shell briquettes?

In manufacture of coconut shell charcoal briquettes use conventional machines through first stages are preparing raw materials, screening, pulverized machines, mixers, blending machines, screw machine molding, conveyors and cutting, and oven machines. However, in manufacture of coconut shell charcoal briquettes that use high pressure machines there are differences in after blending stage, namely using a high pressure machine. High pressure machine is used so that briquette has a very smooth, tight, and compact shape. In addition, on conventional machines final result of coconut shell charcoal briquettes is like piece of knife cut. It means that every surface of coconut shell charcoal briquettes is not exactly smooth. When using high pressure machine all sides are exactly same. Following are the stages of making coconut shell charcoal briquettes using high pressure machines:

  1. Raw Material for Coconut Shell Charcoal; Raw materials determine the final quality of coconut shell charcoal briquettes. Quality raw materials will produce premium quality coconut shell charcoal briquettes. The raw material used is coconut shell charcoal with a maximum moisture maximum of 12% and ash content up to 3%.
  1. Sieve Machine / Screening (Rotary / Vibration); Sieve machine or screening there are 2 types of rotary and vibration. Both have same function, which is to separate dust from charcoal so that the next process is obtained only pure charcoal.
  1. Pulverized machine / crusher; The pulverized machine is used for smoothing and laying coconut shell charcoal. Mesh filters are most commonly used measuring 2-3 mm.
  1. Mixer Machine;  Mixer machines are used to mix charcoal, tapioca and water. Mixer machines can use hot water and use cold water.
  1. Blending Machine; Blending machines are used to unite the materials that have been processed in the mixer machine so that coconut shell charcoal briquettes can be more easily compacted and not too hot. (Ginanjar A, Mahmudi, 2018)
  1. High Pressure Machine; The aim using high pressure machine is to produce briquette  that has a very smooth surfaces, tight and compact shape. In addition, it can increase speed of production and it is not require a lot of employees, and it becomes more efficient. (JCEC,2015)
  1. Oven Machine;  Oven machines are used to dry coconut shell charcoal briquettes completely and it reduce water content in briquettes. (Ginanjar A, Mahmudi, 2018)
