Coffee production moves from green bean handling to roasting, grinding, extraction, and packaging. Each stage uses its own equipment, and the final product decides which machines are needed. A roasted whole bean line is different from an instant coffee line or an espresso capsule line.
Green Bean Processing Equipment
Cleaning and Destoning
A cleaner and destoner removes impurities and stones from green coffee beans. Clean beans protect downstream equipment and support consistent roast results.
Size Grading
A grader sorts green beans by size. Uniform bean size helps the roast develop evenly and gives a more consistent final flavor.
Roasting Equipment
Drum Roasters
Drum roasters are common in coffee production. Hot air or direct heat drives Maillard reactions and other changes in the bean. These reactions create the flavor and color that define the final product.
Roast Degree and Flavor
Roast level determines the final flavor profile. A light roast keeps more origin character, while a darker roast brings out deeper, more bitter notes. The roaster setting should match the bean and the target market.
Grinding Equipment
Burr Grinder Types
Grinders use flat burrs or conical burrs. The burr type affects particle distribution and the flavor extracted during brewing. Burr condition also matters, since worn burrs give an uneven grind.
Grind Size Adjustment
Grind size can be adjusted to suit different brewing methods. Fine grinds work for espresso, while coarser grinds suit drip or French press. The grinder should hold its setting through a production run.
Extraction Equipment
Extraction Tanks for Instant Coffee
For instant coffee production, extraction tanks are a key unit. Hot water or another solvent extracts soluble solids from the roasted and ground coffee. Extraction temperature, time, and flow affect yield and flavor.
Espresso Machines
Espresso machines are used to make espresso. They force hot water through a compacted bed of ground coffee at pressure. The machine setting affects shot strength, crema, and consistency.
Packaging Equipment
Filling Machines
Fillers dose coffee product into packaging containers. The filling step should match line output and keep weight consistent from pack to pack.
Sealing Machines
Sealers close the package to protect product quality and shelf life. Common methods include heat sealing and screw capping. The seal must suit the package material and the product form.
Maintenance and Replacement Parts
Regular maintenance should cover grinder burrs, roaster drum seals, extraction tank valves, filler nozzles, and sealing jaws. Worn burrs affect grind consistency. A worn seal can cause leaks or let moisture into the product. When replacement parts are needed, Hansheng Automation can machine custom components such as grinder burr carriers, filler nozzles, conveyor parts, and sealing jaws to customer drawings.
Our precision custom machining capability is not limited to coffee production lines. Hansheng Automation also produces parts for yachts and RC cars, as well as non-standard components for tobacco packaging machinery, filling machinery, and medical devices. From single parts to small batch runs, we machine to customer drawings and deliver parts for assembly.
