Double Head Servo Rotor Pump Filling Machine with Agitator Hopper for Sauce & Cream

Double Head Servo Rotor Pump Filling Machine for Sauces and Creams

This model combines two independent servo rotary lobe dosing pumps with one 40 L agitator hopper. Its main purchasing distinction is the combination of separate metering at each outlet and a shared moving product supply. The configuration is relevant to compatible creams, thick sauces, and soft-particle products whose filling behavior needs more attention than free-flowing liquid dosing.

The machine fills 10–1000 mL doses through two fixed nozzles. Combined output is 10–40 bottles per minute, subject to the actual filling duty. It includes conveying and filling, while replenishment pumps, bottle unscrambling, and capping are separate equipment decisions.

Evaluate the Complete Particle Passage

For a sauce containing soft particles, assess the whole product pathway. The narrowest or most restrictive point may be a nozzle or connection rather than the pump itself. Particle size, shape, firmness, concentration, and tendency to cluster all affect suitability.

Provide representative product rather than a liquid base without its normal solids. The trial should include the particles and the normal variation expected from production. Where particle appearance matters, compare samples before and after filling using the customer’s acceptance method.

No maximum particle size or particle-integrity guarantee is assigned to this configuration. The related guide to rotary lobe pump filling provides broader application context, while the final selection remains specific to the installed pathway and formulation.

Assess Quantity and Product Composition Separately

A correct total fill does not automatically establish identical particle content in every container. Particle-containing products introduce a second quality question: whether the filled portion contains an acceptable balance of liquid base and solids.

The shared hopper’s agitator helps move the product, but the required conditions depend on the formulation. Excessive agitation may be undesirable for fragile ingredients, while insufficient movement may allow uneven distribution. Establish the operating approach through representative trials.

For acceptance, define both the filled-quantity test and any composition or appearance checks. Sample across the run so the assessment includes changes as the hopper empties or receives additional product.

Check Both Filling Heads Independently

The two filling heads use separate servo-driven pumps. Setup should therefore include an individual quantity check for each outlet. A combined average can conceal a difference between heads if one delivers above the target and the other below it.

Record which outlet produced each test sample. Use the intended dose and product, and repeat checks after changes to the pathway or operating settings. The specified accuracy is ±0.5%; acceptance conditions should define how that performance will be measured.

The filling accuracy testing guide provides further context for sample collection and measurement. Where weight is used to assess a volumetric dose, establish an appropriate method for the actual formulation.

Plan the 40 L Hopper Around Replenishment

The hopper capacity describes available product storage, not the number of containers that can be produced without interruption under every condition. Usable product supply depends on the batch, residual material, and the conditions required to keep the pump inlets supplied.

For a sustained run, review where replenishment product will come from and how it will enter the hopper. Product added from an upstream vessel may differ in temperature, viscosity, or particle distribution if its preparation and holding conditions are not controlled consistently.

An external replenishment pump is optional. Selection should consider the product, transfer route, and replenishment rate needed by the filling operation. The pump selection guide can support that review.

A separate portable rotary lobe transfer pump is one equipment option to evaluate. Its suitability and control arrangement must be assessed for the actual replenishment duty rather than assumed from the shared pump name.

Compare the Pump and Hopper Arrangement with Adjacent Options

Head count alone is an incomplete comparison. The dosing mechanism, product supply, and required formulation handling should be considered together.

The comparison does not imply that either pumping method is universally preferable. Use representative product behavior and acceptance results to establish the appropriate arrangement.

Match Fixed Nozzles to the Container Opening

The filling nozzles operate at fixed positions rather than travelling with continuously moving containers. Bottle and jar presentation must therefore align each opening with the filling outlet.

The listed container-height range is 20–250 mm. Container diameter or width is not specified here, so compatibility must also include the final conveyor guides, spacing, opening size, and stability during stopping and release.

Wide-mouth jars and narrow-neck bottles can create different nozzle requirements even at the same dose. For particle products, the opening and nozzle passage should be reviewed together. A filling volume within 10–1000 mL does not by itself establish package compatibility.

Define the Automation Boundary Before Ordering

The included conveyor supports manual loading of empty containers. Suitable unscrambling equipment can supply compatible bottles automatically. These arrangements change the operator’s loading task, but do not remove the need for material replenishment, quality checks, and line supervision.

The filling machine does not include capping. Match the downstream closing process to the actual container and closure. A separate servo four-wheel screw capper can be evaluated for compatible threaded packages.

When connecting equipment, review container transfer, conveyor elevations, accumulation, and how production stops will be managed. Automatic replenishment controls and line communication should be defined in the agreed scope rather than assumed from the term automatic.

Consider Product Temperature Without Assuming Heating

The standard 40 L hopper includes agitation without heating. If a formulation becomes difficult to fill as it cools, this configuration does not independently maintain its temperature.

Define the product condition at the hopper and during the intended run. A short trial with freshly prepared warm material may not represent a longer production period. Include the expected holding conditions when assessing honey, creams, or sauces whose flow changes with temperature.

Where temperature maintenance is essential, establish a separately assessed process arrangement before purchase. Agitation should not be described as a substitute for heating.

Review Cleaning Access Across Both Product Paths

Two dosing pumps create two product pathways to inspect and clean. The shared hopper also needs attention around the agitator, outlets, and accessible connection points.

For production switching between sauces and cosmetics, assess ingredient carryover, cleaning-agent compatibility, and the facility’s segregation requirements. The machine’s ability to handle both product categories does not establish that they should share equipment without an appropriate cleaning and production plan.

The guide to cleaning access in process equipment provides further points for evaluating residue retention and component access. Automatic CIP or SIP capability is not specified for this configuration.

Build Capacity and Cost Comparisons Around Saleable Output

The rated combined output is 10–40 bottles per minute. It is not a per-head figure, and it should not be multiplied again when calculating potential production.

Saleable output also depends on filling acceptance, container supply, replenishment, downstream closing, cleaning, and changeovers. A faster filling cycle has limited value if another operation repeatedly stops the line.

The total cost of ownership guide helps organize equipment, labor, maintenance, and changeover factors without assigning unsupported savings or payback figures.

• Provide the formulation and its flow behavior at the intended filling temperature.
• Supply representative particles where the product contains solids.
• Identify target doses within the 10–1000 mL range.
• Provide actual bottle or jar samples and opening dimensions.
• Define quantity, particle-distribution, and appearance acceptance criteria.
• Specify manual or automatic container supply requirements.
• Agree on optional replenishment equipment and its control scope.
• Define downstream capping, cleaning, and changeover arrangements.
