Pelleting Requirements of coffee pellet machine

In the coffee pellet fuel pelleting process, coffee residue raw materials usually pass through a cylindrical die hole.

The diameter of the die is generally not greater than 25 mm. The thickness of the die, that is, the length of the die hole, is not greater than 4 times its diameter.

There are usually three diameter sizes: 6mm, 8mm, and 10mm.

The moisture content requirement of raw materials is generally 12%~15%, and the particle size of raw materials is 1~5mm, which is most suitable for pelletizing.

Working Principle Of coffee pellet machine

Working Principle Of coffee pellet machine

The ring-die coffee pellet making machine is mainly composed of motor, distribution box, feeding mechanism, gear box, safety device, pressing roller, die, ring die and other components.

The raw materials are collected and crushed to a certain particle size, the moisture content of the raw materials is adjusted as needed, and then solidified and formed directly. Its molding mechanism is that the core part of the coffee residue, the pressure roller, squeezes the coffee waste recycling raw material with a certain particle size at normal temperature.

Under the action of high temperature and high pressure, the lignin in the raw material begins to soften, the bonding force increases, and the cellulose begins to Through extension and deformation, adjacent particles engage and recombine, and are finally pressed into shape.

The coffee waste pelleting technology only requires two steps: crushing and compression, it has the advantages of simple mechanism, small size, light weight, and low cost.

What’s coffee pellet?

coffee pellets

Coffee pellets are a new type of fuel, mainly using coffee shells, wood waste, etc. as raw materials. After processing, it can be used as a renewable energy source to provide fuel for drying fresh coffee fruits and tea leaves.

It can also be made into parchment paper for packaging green coffee beans.

According to the needs of different customers and the different types of coffee waste actually used, the uses of the granules will vary, and some customers will process coffee granules to process feed or organic fertilizer.

If this is also what you need, please visit our animal feed pellet machine and organic fertilizer pellet machine pages respectively to view product details.

This page will explain in detail the coffee pellet machine that processes coffee pellet fuel.

Why invest in coffee pellet production business?

coffee waste pellet fuel

More than 2 billion cups of coffee are consumed worldwide every day, and most of the coffee grounds are thrown away, with 6 million tons sent to landfills every year. Decomposing coffee grounds releases methane into the atmosphere, becoming a greenhouse gas with a global warming potential 86 times greater than carbon dioxide.

The original intention of producing coffee grounds and coffee shell pellet fuel is to allow coffee companies to reuse hundreds, thousands, or even tens of thousands of tons of coffee shell waste every production season. Coffee remains pelletizing also reduces volume by a 40 to 1 ratio, saving transportation expenses.

Coffee pellet fuel has the characteristics of high calorific value and high density, and is easy to store and transport. The solid and gas emissions after combustion are far lower than those from coal combustion. In recent years, as new energy fuels such as coffee grounds fuel pellets have become the mainstream of the energy market, the production and operation of coffee pellet fuel from coffee shell waste can further enrich the coffee industry.

Complete coffee pellet machine System Construction

The complete equipment process of the fuel coffee pellet production line includes: crushing, drying, granulating, cooling, and packaging. Generally speaking, in a simple coffee biomass pellet production line, 3-5 people can complete the process from crushing to packaging. Large-scale coffee pellets production needs to be determined based on the actual equipment configuration and degree of automation.

01 Coffee pellet production process design

The process of making coffee pellets in biomass pellet plant consists of the following steps.

  1. The moisture content of coffee residues should be from 10% to 15%. If it is more than this amount, you will first need to dry it to make pellets of high quality.
  2. Coffee ground is already in its grounded form so it generally does not need to be crushed. However, if you are using coffee husks you should crush it in a hammer crushing machine to reduce its size as much as possible. Crushing the raw material is necessary to make it suitable for the coffee pellet machine.
  3. Coffee pellet machine has two important parts called dies and rollers that play a crucial role in giving raw material a particular shape and size according to your demands and needs. You can create pellets of different diameters and lengths through this machine.
  4. After bearing lots of pressure, pellets that come out of the coffee pelletizing machines have a high temperature. This temperature must be reduced before these pellets are packed to be sold in the market. Temperature is either by spreading pellets in an open area or by using a cooler.
  5. Finally, pellets are packed either manually or through a machine. Packets used should have your brand name and logo. It is better to use waterproof bags or packets so that pellets do not get damaged by coming in contact with water.
