Automatic Salt Doypack Packing Machine

Application:

Tailored for packaging granular and free-flowing products such as salt, sugar, rice, nuts, grains, and similar fine particles into premade doypacks (including stand‑up pouches, zipper bags, three‑side or four‑side seal formats). Commonly used in food production lines where precise metering and consistent sealing are essential..

Kindly Reminder:

We have experienced team of R & D engineers who can customize packaging solutions according to your product characteristics.

Features:

1. Rotor Volumetric Cup Metering: Uses rotating cups for highly accurate portion control—reliable, cost-effective for granular products like salt and sugar .

2. PLC + Touch-Screen Interface: Advanced PLC with intuitive touch-screen operation delivers stable performance, easy adjustments, and fast troubleshooting.

3.Full Automated Workflow: Z‑type elevator for automatic product feeding; Vertical bag pick-up, ribbon coding, zipper opening; Dual sealing operation ensuring airtight packaging; Finished product discharge conveyor

4. Two-Stage Sealing for Enhanced Integrity: Ensures airtight, secure sealing with double pass heat seal process—ideal for moisture-sensitive goods.

5. Material-Grade Construction: Machine body: 304 stainless steel in product areas; carbon steel with anti-corrosion finish on frame—GMP-compliant, food-grade quality.

6. Automatic Error Detection & Save Function: Features sensors to detect absent or improperly opened pouches, no-fill or no-seal events—halts operation to prevent waste and reuses pouches.

7. Modular & Customizable Design: Compatible with extra functions like date/ribbon coding, gas flush, RFID, perforation, punch holes, or handles through add‑on modules.
