The DFF8 series supplied by Wenzhou T&D Packing Machinery Factory is a semi-automatic two-nozzles liquid & paste spout pouch filling machine (semi automatic two nozzles liquid and paste spout pouch filling machine), an upgrade of the DF8 dual-nozzle stand-up pouch liquid filler platform: it fills both liquid and paste on the same machine and comes standard with a 30 L stainless steel hopper. Material is gravity-fed from the hopper and metered by a piston volumetric system, covering water, juice (no particles), edible oil, liquid detergent, sauce, cream/lotion and other liquids and semi-fluids in one run. The machine uses Airtac (Taiwan) pneumatic components and full-pneumatic drive — explosion-safe, simple to operate, and easy to maintain. Two filling nozzles work simultaneously; both filling volume and filling speed are adjustable; the bottom-close positive-shutoff nozzles keep drips off the pouch mouth. The DFF8-5000 tier delivers a filling range of 5–5000 ml, accuracy within ±1%, and speed 20–60 times/min; air pressure 0.4–0.6 MPa, air consumption 1.1–2.2 m³/h, voltage 220 V 50/60 Hz, semi-automatic grade. Contact parts are food-grade 304 stainless steel (316 optional), N.W. 80 kg, G.W. 100 kg, packing size 129×69×48 cm. Suitable for stand-up pouches, spout pouches and Doypack pouches. Aside from the liquid & paste 2-in-1 + 30 L hopper differences, all other specifications are identical to the DF8 series.

4.2 Frequently Asked Questions (FAQ)
Q1. What is the difference between DFF8 and DF8 series?
A. Only two differences: DFF8 can fill both paste and liquid (2-in-1) and comes standard with a 30 L hopper; DF8 only fills free-flowing liquid and does not include a hopper. All other specifications (two nozzles, piston volumetric filling, within 1% accuracy, full-pneumatic drive, etc.) are identical. Choose DF8 if you only fill liquid — lighter and simpler; choose DFF8 if you need both paste and liquid.
Q2. What kinds of paste can the DFF8 fill?
A. Suitable for flowable pastes and semi-fluids: sauce (chili sauce, tomato sauce, thin sauce), cream, lotion, honey, jam, liquid cream, etc. Material is gravity-fed from the hopper and metered by the piston. For high-viscosity, non-flowing pastes (e.g. very thick cream), please provide a sample of the material's viscosity/flowability to the factory for confirmation.
Q3. Does the DFF8 need an air compressor?
A. Yes. DFF8 is fully pneumatically driven and must be connected to an air compressor. Working pressure 0.4–0.6 MPa, air consumption 1.1–2.2 m³/h — please size the compressor against the upper limit of air consumption.
Q4. Does the machine need to be connected to electricity?
A. 220 V 50/60 Hz power is required (as listed in the quotation). Drive is fully pneumatic; electricity is only used for the auxiliary control section.
Q5. How do semi-auto and auto modes switch?
A. The piston filling supports foot pedal operation or auto-timer cycle, and can be transferred between semi-automatic and automatic modes. Semi-auto suits sampling and small batches; auto-timer suits continuous batch production.
Q6. Does the ±1% filling accuracy include the pouch itself?
A. ±1% refers to the machine's own volumetric filling accuracy; it does not include pouch tolerance, pouch expansion, or operator handling error. For higher overall accuracy, please verify with calibrated sample pouches.
Q7. How to choose the nozzle diameter?
A. Nozzle diameter is optional within 3–12 mm. Small diameters suit low-viscosity liquids; larger diameters suit pastes / high-viscosity materials. The diameter must also match the pouch mouth inner diameter. Before ordering, please provide the material viscosity and pouch mouth size, and the factory will recommend the right diameter.
Q8. Which pouch types are supported?
A. The machine is professionally adapted to stand-up pouches, spout pouches, and Doypack pouches and other flexible packaging. The special filling head drive allows the filling head to rise and fall automatically, following the pouch mouth during filling.
Q9. What are the options for sealing components?
A. Standard silicone O-ring, 200 °C rated, food safety compliant. For anti-corrosion products (e.g. corrosive daily chemicals, chemical liquids) a rubber sealing ring can be selected. Please choose based on material properties when ordering.
Q10. What is the warranty policy?
A. One-year warranty on the whole machine. During the warranty period, damage caused by normal use per the manual is covered by free repair or free spare-part replacement (freight from China to the customer's location borne by the customer). If an engineer is required on site, the customer's travel expenses are borne by the customer. Lifetime repair service is provided after the warranty period.
Q11. What is the MOQ and lead time?
A. MOQ 1 set, lead time within 10 days, trade term EXW Wenzhou. For the latest price and payment terms, please contact our sales team.

6. Workflow
6.1 Operator Workflow (Per Shift)
- Air source check — confirm the air compressor is on, the pressure is stable at 0.4–0.6 MPa, and the air source can meet 1.1–2.2 m³/h consumption
- Material preparation — pour liquid or paste material into the 30 L hopper; for thicker pastes, confirm the material can flow down by gravity
- Power on — connect the air source and 220 V power, select foot pedal / auto-timer mode
- Adjust volume — adjust the piston stroke to set the filling volume based on the pouch specification, and adjust the filling speed if needed
- Select nozzle — replace the nozzle with one of matching diameter (3–12 mm optional) according to the material viscosity and the pouch mouth inner diameter: small nozzle for thin material, large nozzle for thick material
- Test fill — perform 3–5 test fills; weigh and verify the filling volume is within the ±1% target range
- Formal production — the operator places the pouch under the filling head; the filling head auto-rises and falls to align with the pouch mouth and triggers the fill; two nozzles fill two bags at once
- Mid-run sampling — re-weigh every 30–60 minutes to confirm accuracy has not drifted; check the nozzles for any liquid hang and clean if necessary
- End-of-shift cleaning — rinse the hopper and material path with clean water or a suitable cleaning agent (paste products must be cleaned thoroughly), wipe down the machine body, and shut off the air source and power
6.2 Buyer Decision Workflow (Reference)
