Spray Dried Coffee

Spray-dried instant coffee is a fine, free-flowing powder that gives up aroma quickly once exposed. High-barrier films, dry dosing paths and optional nitrogen flush protect solubility and taste. Single-cup sticks — often in 3-in-1 constellations — are the format that built the instant category. The difficulty on the line is not making the powder move; it moves readily. It is what happens around the movement. The particles are light, so they ride on the air displaced at each fill and drift toward the sealing area, and a few milligrams caught in a seal jaw leave a channel that lets moisture in later. The powder is also hygroscopic: an open dosing path in a humid room cakes on hopper walls and auger flights, and caking shifts the dose before anything becomes visible. Auger dosing is the usual answer for a spray dried coffee filling machine. A servo-driven auger meters by counted revolution rather than by a timed gate, and the uniform, free-flowing structure spray drying produces is what an auger repeats well at small doses. Where bulk density is stable and runs are long, volumetric cup dosing is a faster, lower-cost alternative; where the recipe changes between plain coffee and a 3-in-1 blend, the auger holds accuracy through the change. Dust extraction over the filling zone and a closed path from hopper to lane keep the seal area clean. The stick pack is the format the category was built on: one cup, one stick, nothing to measure, and a pack that fits a hotel tray, a vending unit or a pocket. A spray dried coffee stick pack machine is therefore the usual enquiry, most often for 3-in-1 and 2-in-1 blends beside plain coffee. Four-side-seal sachets are used where the dose is larger or the printed face has to carry more information — foodservice, catering, export private label. VFFS pillow bags cover refill and bulk presentations, and collate finished sticks into retail multipacks. Doses sit in the 1-3 g range. Output is cycle rate multiplied by lane count, and lane count follows pack width rather than the machine alone. On narrow sticks a CSM1200 runs 12 lanes and reaches up to 960 packs per minute; the same machine on a wider pack runs 6 lanes and gives up to 480 packs per minute. Lane counts across the range: CSM600 3-7, HSM 1-3, ARTISTICK 1-5, CSM1200 6-12, ISM400 2-5, SPM1200 7-12, SPM320 1-8, SPM800 4-12. Machines suited to spray dried coffee sachet packaging and stick filling: CSM600, CSM1200, HSM, ARTISTICK, ISM400, SPM320, SPM800 and SPM1200. Selection follows pack width, dose and required output. Typical buyers are instant coffee producers and roasters with a soluble line, 3-in-1 blenders, private-label co-packers serving retail chains, and suppliers to hotel, vending and foodservice channels, where the same stick format serves both domestic retail and export.
