Description

Coffee Tech’s Destoner works on a gravity principle by using the relatively light weight of the coffee beans to detect other foreign objects that might be found, such as stones and metals.
De-stoner is equipped with an adjustable large volume air blower, creating a vacuum tunnel for separating the coffee beans from heavier weight foreign particles.
Consequently, we receive a clean product containing 100% pure coffee, without risking our customers or their equipment.

Coffee-Tech’s Destoners are built specifically to achieve such operation with the highest accuracy.
Thanks to its clever design and engineering, a correct ratio between the beans’ screen, their surface area and quantity of air is maintained, making the Destoner very sensitive to the smallest stones that might be found inside the coffee.
The user regulation interface is performed using a digital frequency inverter for consistency, repeatability and accuracy, and with a resolution of 0.1Hz you can be certain that your Destoner will perform its task to perfect guaranteed results.

Integration
The Destoner is fully integrated into your roaster, connected directly to the beans’ exit from the cooling pan.
Evacuating the cooled beans directly to the de-stoner without a middle stop in the process.
All you need to do is to open the cooling group door and push the De-stoner button.
The operation switch, de-stoner power alimentation and frequency inverter interface are all integrated into the machine and need no extra infrastructure or installation.

Small footprint
Like all our products, the Destoner excels in a small footprint to save floor space at your roastery.

User-friendly
We are always thinking about the roastery day-to-day routine and performance and how we can improve and achieve higher efficiency.
That’s why we integrated the Destoner’s operation from the main control panel of the roaster.
As a roast master, working at the roastery you would be multi-tasking all day long.
This includes operating the roaster, preparing the next batches, and making sure you are keeping your roaster working continuously.
These batches won’t be preparing themselves, so operating the gear from one central point is something that you will enjoy, without the need to move between different control boxes and switches.

Why you need a Destoner
From the moment the coffee beans are picked until they reach the consumer’s serving cup, it takes a long road with several stopping points where the beans need to be processed and sorted.
These processes include harvesting, picking, conveying, carrying, drying, washing, pulping, sorting, bagging, and transporting to the green beans’ warehouse.

Coffee, as with many other natural commodities, contains a minor percentage of such particles such as small stones, falling pieces of metal from machinery, wooden sticks, and similar.
Despite the sorting and bagging process, some foreign objects find their way into the coffee bag and the beans inside, and eventually end up in landing inside the coffee roaster’s drum.

All coffee beverages require roasting and grinding before preparation.

If a stone or a similar foreign object reaches the grinder, it might cause severe mechanical damage, or even complete dysfunction of the grinder itself.
Moreover, it can endanger the roastery’s reputation and harm the brand value in the eyes of the consumer.

The purpose of the Destoner is to separate these stones and particles from the roasted coffee, before the roasted beans are bagged or ground.

Coffee Tech Engineering guiding principles in the making of Silon ZR7:

• Advanced Thermodynamic Characterization: A tightly sealed and controlled ceramic combustion chamber design inspired by our extensive research into conductive and convective heat pathways.

• Robust and Accurate Drum Housing: Ensuring perfect alignment of drum spin throughout the product’s entire lifecycle. Greased hemispherical bearings, zero-tolerance precision dry-slide bearings, and a micrometric mechanism to adjust drum gap ensure the edge of the drum stays perfectly perpendicular to the front plate of the machine at minimal tolerance.

• Drum Proportion: Optimizing ratio of bean mass to metal contact area for a superb conductive thermal dialog.

• In-drum Variable Agitation: Designed for perfect bean stirring, greater heat conduction between metal and beans, effective chaff separation, and immediate evacuation of beans from the drum into the cooling group.

• Monitoring and Control: Monitoring of drum air and bean temperature. Digital control of drum revolution speed, drum blower speed, drum aspiration rate, and the fully modulated pre-mix turbo gas burner.

• Perfect Heat Dispersion: A sophisticated heat dispersion scheme involves thermal flow emanating from the heat source located at the bottom towards the top of the structure using secondary airflow propelled by well-calculated jets of air. Specifically designed perforation at the top front end of the combustion chamber allows air to flow in in precise ratio.

• Fully Modulated Pre-Mix Turbo Gas Burner: The Burner is fully controllable from low power to overkill with high frequency of infrared reflection towards the drum. Ultra low NOx specs in infrared flame screen achieve the cleanest, most efficient energy production. No soot accumulation in the drum or harmful CO emission.

a tool for baristas who craft their own beans, batch by batch. 

Featuring a New Generation of Roasting Drums:
An extensive research and development process has resulted in three distinctive tailor-made drum models for the Silon ZR7 line:

⭐️ Silon ZR7 T4 Drum - This solid mild steel drum was designed to produce an extensive aromatic range and high sugar levels during roasting with a higher degree of safe but daring heat conduction. This results in a superb roast for most styles, including blends roasted for espresso.
⭐️ Silon ZR7 Infrared Drum - This drum is designed to produce a stronger taste with higher levels of caramelized sugars and excels in rapid roasting times. Two separate layers of perforated mild steel, the inner one promoting an improved grip of the beans, ensuring advanced agitation and a larger contact surface area between the beans and the heating source. High frequency infrared radiation emanating from the advanced pre-mix turbo gas burner is applied to the beans via the perforated layers.
⭐️ Silon ZR7 Thermodynamic Drum - This is the most advanced drum available in today’s industry. Built from two layers of mild steel with a middle layer of pure copper, it has extremely high thermal absorption and heat conduction characteristics. In contrast to standard drums in which roasting is performed by direct, limited contact between the beans and the drum, the Silon ZR7 Thermodynamic Drum exhibits a unique scheme of sophisticated heat conduction applied to a wider contact surface between beans and drum. Heat is transferred via the copper layer creating a 1.4 mm gap between the heat and the beans, removing any risk of burn marks. This drum excels in producing an evenly roasted batch of superb beans, allowing a higher range of temperature operation, and writes its own new language in thermal dialog – just imagine, reflected heat conduction.

The Ghibli R30 Commercial Coffee Roaster is an adv The Ghibli R30 Commercial Coffee Roaster is an advanced roasting machine that allows perfect control over the roasting process, in order to meet the desired results and cup profiles. The Ghibli R30 enables roast masters to pre-define their desired calibration preferences.

🔥Next-Generation Vortex Roasting Drum:

The Ghibli R30 blasts an airstream in spiral motion into the drum and through the coffee bean mass, requiring a smaller amount of air to enter the roaster for a full effect. The longer spiral path across the drum and through the coffee bed is unlike the olden traditional roaster mechanisms, which had a perforated back plate allowing huge amounts of air into the drum in a short, straight path. With our Ghibli line, the beans are not stripped from their natural coffee aromas or taste. The energy of the airflow is also used to maintain the heat next to the exhaust. This innovative approach ensures a unique added-value for cost-effectiveness, energy optimization, and enhanced flavor. Lab tests have already shown a huge improvement in the coffee’s solids content and density, with amazing improvements in gas consumption, roasting time, and fume emissions.

⭐️ Advanced set of features:
• Advanced thermodynamic characterization.
• Smart Vortex drum, allowing 90% less air to alter the heating characteristics.
• Fully modulated burner, providing precise control with 100% burner power resolution.
• Option for two gas burners.
• Dual positioning option for the burner relative to the drum.
• Precision drum housing, to ensure the drum always spins “in line”, with a sturdy design.
• In-drum fluidizing paddles, designed to perfectly stir the beans.
• A high capacity, high pressure cooling blower provides a substantially shorter batch cooling time.
• LED-illuminated magnifying glass, for better trier sample viewing
• Enhanced visibility with three tempered glass lenses encircle the roaster. These lenses provide easy viewing into the combustion chamber, green hopper window, and into the drum to view your beans while roasting.
