2-to-16 Head SUS316L Servo Piston Sauce & Chili Jar Fillers (±0.2%)

Fill 100–5,000 ml wide-mouth glass and PET jars with chunky pasta sauce, salsa, chili crisp, peanut butter, and curries at 14–80+ BPM and ±0.2%–0.5% accuracy.

Positive-Displacement Power for Thick Pastes & 20 mm Whole Particulates

When filling 95,000 cP sesame/peanut paste, fermented bean paste, or marinara loaded with 15 mm diced vegetables and mushrooms, gravity and centrifugal pressure do nothing—you need positive-displacement ball-screw servo piston suction and thrust. Inside sauce bottle and jar filling lines, our VK (4–16 head) and MIC-ZF12 / ZF20 (3,000–4,000 BPH) jar fillers combine wide-throat Ø28–38 mm three-way rotary spool valves with jacketed agitated U-hoppers.

Every cylinder stroke draws directly from the bottom of the mixed hopper without dead pipe bends where chili flakes or garlic dices can bridge.

Six-stage 85 °C hot-fill sauce jar line from pre-warm rinsing through rotary-valve piston filling, vacuum capping, cap inversion, and cooling
Tilting capped hot-fill bottles 90–180° for 20–30 seconds sterilizes cap headspaces using the sauce's own 85 °C thermal energy.

See how we prevent oil-solid separation in chili crisp, salsa, and chunky sauce lines.

Engineering workflow preventing oil-solid phase separation in chili crisp, chimichurri, and pesto jar filling
When exact solid-to-oil ratios are critical, dual-stage dosing deposits drained chili/garlic solids first and tops off exact oil weight second.

Sanitary Sauce & Hot-Fill Notes

  • Double Safety Interlock: No-Jar / Backup-Jam = No-Fill: Upstream entry counters + downstream backup photoeyes ensure pistons never cycle unless exact jar count is clamped squarely under diving tips.
  • Anti-Crush Flexible Silicone/PTFE Spool Clearance: For delicate whole black beans, corn kernels, or fruit chunks, relief-chamfered rotary valves shear cleanly without turning whole pieces into mush.
  • Heated Water/Oil Jacket + Scraper Blades: Thermostatically controlled double-wall hoppers with PTFE wall scrapers prevent caramelization or fat solidification on peanut/cheese sauces.
