Product Description

The Servo rotor pump sauce sachet packing machine forms bags, fills, seals, and cuts viscous food products into stick packs and sachets in one continuous sequence. Ketchup, mayonnaise, chili sauce, jam, honey, salad dressing, chocolate sauce — products that contain pulp, fine particles, or vary significantly in viscosity across the range.

A servo-driven rotor lobe pump drives the fill. Rotor lobe pumps move product through low-shear rotation rather than high-pressure displacement — which is the relevant distinction for products containing pulp or particles, where a piston or gear pump at filling pressure would break down texture or fragment particles before they reach the sachet. Servo actuation controls rotor speed precisely rather than running at a fixed rate, which keeps fill volume consistent when product viscosity shifts between batches.

A servo film feeding system controls pouch length. One-touch adjustment changes bag length at the panel rather than through mechanical recalibration at the film feed — relevant when switching between a small condiment sachet and a larger sauce portion on the same line.

For temperature-sensitive products — honey, chocolate sauce, thick jams — an optional heated mixing hopper maintains product temperature and viscosity between refills. Ambient cooling between batches changes how the product flows through the pump; the hopper addresses that before the variation reaches the filling stage.

Custom sachet shapes and multiple sealing styles are available for operations where packaging format is part of the brand differentiation rather than a standard commodity specification.

Machine Features

Servo Rotor Lobe Pump Filling

The servo-driven rotor lobe pump provides gentle and accurate filling for high-viscosity food products, maintaining product texture while ensuring consistent filling accuracy.

 

Integrated VFFS Packaging

Automatically completes bag forming, filling, heat sealing and cutting in one continuous operation to reduce labor costs and improve production efficiency.

 

One-Touch Pouch Length Adjustment

The servo-controlled film feeding system enables operators to adjust pouch length directly from the touchscreen without mechanical changes, reducing setup time.

 

Optional Heated Mixing Hopper

The 50L U-shaped hopper can be equipped with mixing and heating functions to keep sauces evenly blended and flowing smoothly throughout production.

 

Multiple Sachet Styles

Supports back seal, three-side seal and four-side seal sachets, with customized cutting dies available for unique pouch shapes.

 

Precise Temperature Control

Independent temperature control for upper and lower sealing jaws helps achieve reliable seals across various laminated packaging films.

Machine Details

control panel of sachet filling machine
PLC Touchscreen Control

Filling volume, pouch length, production speed, and sealing parameters adjust from one interface without stopping the line. Saved recipes mean switching between a ketchup sachet and a honey stick pack — products with different fill volumes, pouch lengths, and optimal pump speeds — is a recall rather than a manual re-entry of every parameter from scratch.

Servo Rotor Pump

Compared with piston pumps, the servo rotor lobe pump transfers viscous food products more gently while maintaining stable filling accuracy. It is especially suitable for sauces containing pulp or soft particles and is easier to clean after production.

50L U-Shaped Hopper

The U-shaped base eliminates the corners where product accumulates in standard rectangular hoppers. Optional mixing and heating functions run during production. Mixing keeps particle-containing products — sauces with pulp, jams with fruit pieces — from separating between fill cycles. Heating maintains product temperature and viscosity for honey, chocolate sauce, and thick condiments where ambient cooling between refills changes how the product flows through the rotor pump.

Servo Film Feeding System

A servo motor precisely controls film movement for consistent pouch dimensions. Operators can change bag length through the control panel without replacing mechanical components.

Intelligent Heat Sealing

Horizontal and vertical sealing bars run under independent temperature control. Different seal orientations on the same sachet often require different heat settings — the vertical seal running along the length of the stick pack and the horizontal seals closing each end face different film thickness and tension conditions at the point of contact. Independent control removes that tradeoff — each bar holds its own setting regardless of what the other is doing.

Customized Cutting System

Interchangeable cutting molds produce standard sachet cuts, stick pack profiles, and custom shapes for promotional or brand-differentiated packaging. Format switches through mold replacement rather than machine reconfiguration — a standard condiment sachet and a shaped promotional pouch run on the same system, separated only by a tooling change.

How Does the Sauce Sachet Packing Machine Work?

  1. Food paste is transferred into the hopper.
  2. The servo rotor pump accurately meters each filling dose.
  3. Packaging film is formed into a sachet.
  4. The machine fills the product into the formed pouch.
  5. Heat sealing closes the package securely.
  6. The cutting system separates individual sachets.
  7. Finished sachets are discharged automatically for collection.

  • Improve packaging consistency
  • Reduce product waste
  • Increase production efficiency
  • Handle high-viscosity sauces smoothly
  • Support custom branded sachets
  • Lower labor requirements
  • Easy parameter adjustment
  • Suitable for small and medium batch production

Frequently Asked Questions

What products can this machine package?

It is suitable for ketchup, mayonnaise, honey, jam, peanut butter, chocolate sauce, salad dressing, cheese sauce, chili sauce and many other viscous food products.

 

Can it package products containing small particles?

Yes. The servo rotor lobe pump is suitable for many viscous products with soft particles or pulp, helping maintain product quality during filling.

 

Does it support different sachet styles?

Yes. It supports back seal, three-side seal and four-side seal sachets, with customized cutting dies available for special-shaped pouches.

 

Can the hopper be heated?

Yes. An optional heated mixing hopper is available to maintain product temperature and viscosity for materials that require gentle heating.

 

Is the machine suitable for different filling volumes?

Yes. The filling range can be customized according to your production requirements and product characteristics.

 

Can a date coder be integrated?

Yes. An optional date coding system can be added to print production dates, batch numbers or expiration dates directly onto the packaging film.
