Multi-Lane Powder Stick Packing Machine

Feature

The LTC Multi-Lane Powder Stick Packing Machine is designed for high-speed, contamination-free packaging of dry powders, nutraceuticals, and instant beverage mixes. Utilizing individual servo-driven auger screws for each lane, it ensures exceptional dosage accuracy (±1%) even at high cycle speeds. Compatible with various heat-sealable films, it delivers sleek, leak-proof, and easy-to-open stick pouches that comply with international food and pharmaceutical standards.

Working Process 

1. Film Unwinding & Slitting: Master film roll is unwound with constant tension control and precision-slit into multiple strips.

2. Tube Forming: Each film strip is shaped around a stainless steel forming tube.

3. Vertical Sealing: Heated vertical seal bars seal the rear overlap of each stick.

4. Auger Dosing: Servo augers dispense precise powder charges into each formed tube.

5. Horizontal Sealing & Cooling: Cross seal jaws seal top/bottom seams and apply tear notches.

6. Cutting & Discharge: Flying knives or die-cut punches separate sticks onto the discharge conveyor.

Applications 

• Food & Beverage: Instant coffee 3-in-1, milk powder, matcha tea, matcha latte, electrolyte mix, cocoa powder.

• Health & Nutraceuticals: Collagen powder, probiotic powders, dietary fiber, vitamin mixes.

• Pharmaceuticals: Herbal powder extract, cold medication powders, oral rehydration salts.

FAQ

Q1: How does the machine ensure consistent filling accuracy across all lanes?

A: Each lane is powered by an independent servo motor driving its own precision auger screw. Unlike mechanical multi-lane linkages, individual servo control allows independent parameter micro-adjustments via the touchscreen, guaranteeing dosing accuracy within ±1% across all lanes simultaneously.

Q2: How do you prevent dust from contaminating the seal area during powder filling?

A: We integrate three synchronized dust-control mechanisms:

1. Extended filling tubes that insert deep into the stick pouch before discharging.

2. An integrated negative-pressure dust extraction vacuum hood around the sealing zone.

3. Pneumatic cut-off shut valves at the auger tip to eliminate powder trailing.

Q3: Can the machine handle hygroscopic, sticky, or poorly flowing powders?

A: Yes. For sticky, non-free-flowing, or static-prone powders (e.g., instant coffee, protein powders, herbal extracts), we equip the hopper with continuous horizontal agitation, pneumatic bin vibrators, and electrostatic discharge (ESD) bars to eliminate product bridging and wall cling.

Q4: How long does cleaning and material changeover take?

A: The material hopper and auger tooling feature tool-less quick-disconnect clamps. A full dry clean and material changeover can be completed in approximately 15 to 25 minutes, minimizing downtime between product batches.

Q5: Can I pack different stick widths and lengths on the same machine?

A: Stick length is adjusted digitally on the touchscreen PLC in seconds. Stick width is determined by the forming tube assembly and slitting cutter spacing; changing the stick width requires replacing the dedicated multi-lane forming set, which typically takes under 45 minutes.

Q6: What packaging films are compatible with this powder stick packer?

A: The heating and sealing system handles a wide variety of heat-sealable laminated barrier films, including PET/AL/PE, PET/PE, Paper/PE, and emerging eco-friendly mono-material recyclable films (such as MDO-PE/PE).
