Coffee is popular among people in today’s age as a functional beverage that can replenish energy and boost vitality. However, the large amount of coffee consumed each year leaves behind a large amount of residues that are thrown away as garbage, such as coffee grounds and coffee husks.

In fact, these residues can be utilized in a way that promotes material recycling and alleviates the problem of tight energy supply. And making biomass pellets from coffee husks and grounds is a good way to deal with them.

A coffee pellet maker is ideal for converting the remaining coffee residue into pellets. This video shows the Coffee Pelletizer manufactured by RICHI Machinery. It consists of a reverse arch silo, a forced feeder, a Siemens motor and a pelletizing chamber.

The machine is capable of pressing all kinds of biomass raw materials into compact biomass pellets, which are used for heating in homes, schools and industries. The pellets produced are smooth on the outside and firm on the inside, which are very popular among customers.

Why make coffee pellets?

Coffee grounds and coffee husk pellets are a great biomass pellet fuel, and here are the benefits of coffee pellets as summarized by RICHI Machinery. I believe that after understanding this, you will understand why make coffee grounds and coffee husks into pellets!

  • Pellets are small and dense, easy to carry and transport. It can reduce and minimize the storage cost.
  • Coffee grounds pressed into pellets can increase the calorific value of the product, and will produce less ash when burned.
  • Turning waste into treasure, coffee grounds and husks have always been considered as garbage waste. Until the advent of pelletizing machines, which solidify them into usable biomass fuels, their utilization value has been greatly increasing.
  • Increase income for people. Coffee grounds and shells are abundant and cheap raw materials, and people only need to buy a pelletizer to press coffee residues into efficient and environmentally friendly biomass coffee pellets.
  • Coffee husk pellets and coffee residue pellets are a good raw material for biomass, with a high calorific value of 3900-4800 kcal/kg, and 7000-8000 kcal/kg after carbonization, which is suitable for use in large boilers.
  • Coffee pellets produce very little ash after combustion, which can greatly reduce the site for stacking cinder and reduce the cost of slagging.

Complete process of making pellets with coffee pellet machine

The process of making coffee pellets is generally: crushing – drying – granulating – cooling – packaging. Of course, the production process of customers with different needs will also be different. RICHI Machinery will reasonably customize a set of coffee pellet production line scheme according to customers’ raw materials, production conditions and production needs. Here are the steps to make coffee pellets:

process of making pellets from coffee husks and coffee ground

01 Crushing process: coffee crushing machine

If the raw material is coffee grounds, there is no need for a crushing plant. If the raw material is coffee shell, it must be crushed with 2-3mm powder for pelletizing.

02 Drying process: coffee dryer

This step also depends on the water content of the raw material. If the water content of the raw material is high, it is necessary to use the conveying equipment to transport the raw material to the dryer for drying. Because before making coffee pellets, it is necessary to ensure that the water content of the raw material is about 15%. Drying the raw material of the coffee shell or grounds to a suitable moisture content is essential for the production of high-quality coffee pellets. Of course, if the water content of the raw material is too low, water can be added, or the raw material with high water content can be mixed.

03 Pelletizing process: coffee pellet machine

The machine used to press coffee shells or coffee grounds into coffee pellets is a coffee pellet machine. There are usually two types of flat die and ring die. Flat mold coffee pellet machine is suitable for small volume pellet production. Its working principle is mainly through the relative movement of the press roller and the press die to clamp, compress and compact the raw material into the die hole, and form pellets through the die hole after cutting. The ring die pellet machine is suitable for a wider range, its output can reach 0.6-10T/h. Its main working principle is to rely on the extrusion of the ring die and the press roller, the raw material is squeezed into the ring die hole to form, and constantly extruded to the outer end and cut by the cutter device to the ideal length.

04 screening section: coffee pellet screener

Not all of the pellets produced are usable. The molding rate of the general pelletizer is more than 98%, which means that some pellets are unqualified. For example, some will break into small pieces or powder, which needs to be sifted into the pelletizer for the next batch of pelletizing. Of course, there will be some oversized coffee pellets, which need to go into the crusher for crushing, and then pelletizing.

05 cooling process: coffee pellet cooling machine

Freshly made coffee pellets leave the coffee pelletizing machine at very high temperatures and humidity. It needs to be cooled and dried. At this point, you can choose to air dry, or a faster and more efficient way – use a cooling machine.

06 Packaging process: coffee pellet packing machine

Once cooled, the coffee pellets are transported to a packaging machine for packing. This is the final step in making pellets. Here RICHI Machinery reminds customers that the pellets must be kept in a dry place, otherwise the pellets will absorb water in the air, expand, and cause losses to the manufacturer, which is of course, we are not willing to see the situation. Generally, coffee pellets will be packed into plastic bags, because this is an easy to carry size. Of course you can also take large bag packaging, bulk, or large silo storage.

FAQ about the coffee pellet machine

How does coffee pellet machine work?

 To understand how the coffee pellet machine works, let’s take a look at the composition and structure of the coffee pellet mill. The pellet machine mainly consists of power device, feeder, discharge port, press roll, ring die and so on.

Among them, the power plant is mainly driven by Siemens motor. The feeder is equipped with a variable frequency speed regulating motor, which can control the feeding speed and feeding amount of the granulator to achieve uniform feeding and make the material form more uniform. And can maximize the production capacity of the granulator.

During pelletizing, the crushed coffee shell or coffee grounds enter the coffee pelletizing machine through the feeder, and under the extrusion and friction of the ring die and press roll of the pelletizing machine, the raw materials are extruded from the ring die and form coffee pellets.

The pressed pellets are very dense and have a low water content, which allows the coffee pellets to be incinerated with a very high combustion efficiency.

Coffee pelletizer adopts advanced high-quality technical process, and its service life and wear resistance are 3-5 times higher than that of ordinary granulator. The machine has stable performance, good pressing effect and high forming rate. It is an ideal granulation equipment for turning coffee waste residue into treasure.

How much does a coffee pellet machine cost?

Coffee pelletizer prices vary greatly depending on machine features, output and brand. Generally, coffee pellet machine cost between $10,000 and $50,000. The price of different models of machines is not ventilated, and the price of the same model of machine with different output will also be different.

For example, the price of a 600-800kg/h coffee granulator is around $10,000 USD, while the price of a 10T/h granulator starts from $60,000 USD. Below I will introduce several factors that affect the price of coffee granulator.

Factors affecting the coffee pellet machine price

There are very many factors that affect the cost of a coffee pelletizer, the type of machine, the output, the brand, etc., all of which affect the price. Below is a list of some of the more obvious factors for you to consider, as listed by RICHI Machinery.

Types of Coffee Pellet Mills

Different types of pellet mills have different prices. Flat die pellet mills are usually cheaper, around a few thousand dollars. However, it has obvious disadvantages such as low output and low productivity. This is not good for mass production of coffee pellets. Ring die coffee pellet mills are usually more expensive, but they are more widely available and have high efficiency and production. The coffee pellets produced are superior in both appearance and quality.

Production Capacity of Coffee Pellet Machine

The output of a coffee pellet maker directly affects the price of the pellet machine. As with most machines, the higher the output, the higher the price of the machine. But larger output pellet machines have a wider range of applications, and they are certainly the best choice for large pellet production lines.

Choice of Coffee Pellet Machine Manufacturers

The price of pelletizing machines can vary from brand to brand and from manufacturer to manufacturer. This is closely related to the quality of their products, brand reliability, after-sales service, technical capabilities and so on. Maybe the cheaper machine is more attractive for people to buy, but the quality of the machine and the perfect after-sales service should be the most important thing to consider. We recommend that you can compare several granulator manufacturers and conduct on-site inspection of factories, and then make a choice.

Factors affecting the coffee pellet machine price

There are many other factors affecting the price of the coffee pelletizer, such as the shipping cost to different places and the tax may be different, which will also generate some prices. In addition, if you intend to build a coffee pellet production line, then in addition to the coffee pelletizing machine, you may also need to purchase a series of pelletizing equipment such as crushing equipment, cooling equipment, baling equipment, conveying equipment and so on according to your needs, and the costs of these machines need to be taken into account as well.

Overall, we should choose a coffee granulator from a long term perspective. The price of the machine will certainly affect the initial cost, but there will be corresponding operation and maintenance costs. The economic benefits generated by the operation of the machine is what we should consider most.
