Automatic Pesticide Filling Machine for 50–1000 mL Bottles

Bring controlled dosing and coordinated bottle handling to your agrochemical packaging process. The Sierac filling solution combines eight filling nozzles with servo-driven piston metering, supporting bottle formats from 50 to 1000 mL. Each project is configured around the formulation, container and required production rate, with interfaces planned for downstream capping, labeling and case packing.

Product Overview

Engineered Around the Formulation, Bottle and Production Target

Agrochemical manufacturers need to balance output with fill control, cleaning requirements and packaging flexibility. A machine selected only by its maximum speed may not deliver the required results across different formulations and bottle sizes.

Sierac approaches filling as part of the complete packaging process. Product properties determine the suitability of the dosing system and wetted components. Bottle geometry determines nozzle access and handling requirements. The required finished-pack output provides the basis for coordinating filling with downstream operations.

This eight-nozzle configuration provides a starting point for automating small-format agrochemical bottle filling, with final specifications established through application review and sample testing.

Core Attributes

• Application: Bottled agrochemical liquids, subject to formulation review.

• Filling range: 50–1000 mL.

• Filling configuration: Eight nozzles with piston metering.

• Motion control: Servo-driven piston movement.

• Operation: PLC control with an HMI.

• Container formats: Round, flat and square bottles within the approved dimensional range.

• Line planning: Interfaces for upstream bottle feeding and downstream packaging equipment.

Functional Modules and Production Value

1. Servo Piston Metering — Control the Dose at Its Source

   The servo drive controls piston travel through a synchronous belt and twin-screw mechanism. Controlled displacement provides the basis for repeatable filling.

   For the factory, this supports a defined filling setup that can be checked against actual sample weights, helping manage variation and unnecessary product giveaway. Final accuracy must be established with the intended formulation under agreed test conditions.

2. Eight-Nozzle Filling — Match Capacity to the Pack Format

   Eight filling positions support automated bottle production across the specified volume range. Output depends on the time required to dispense the product and handle the container.

   Capacity planning should therefore use the intended pack size and formulation. This helps production teams balance the filler with capping, labeling and packing, reducing the risk of selecting downstream equipment against an unrealistic headline speed.

3. Cleaning Access — Support Controlled Product Changeovers

   The separable piston-cylinder arrangement provides access for product discharge and cleaning. Accessible wetted components help operators remove residual material before changing products.

   For facilities processing multiple formulations, the cleaning method, inspection points and acceptance criteria should form part of the production procedure. Mechanical access supports cleaning; verified cleaning results determine readiness for the next batch.

4. Bottle Format Matching — Define Compatibility Before Production

   Bottle compatibility depends on more than nominal volume. Container width, height, opening diameter and dimensional variation all affect filling access and handling.

   Reviewing physical samples before final configuration helps define the required guides, nozzle clearances and format adjustments. This gives production teams a practical basis for introducing approved bottle sizes.

5. Operator Interface — Organize Setup and Daily Operation

   The PLC and HMI provide the control platform for machine operation. Project-specific operating screens and adjustment permissions should be defined around the tasks performed by operators and maintenance personnel.

   A clear operating sequence helps make setup, production checks and fault recovery easier to follow.

Reference data is subject to final configuration. Output and accuracy depend on the formulation, container, supply conditions and test method. Electrical requirements are confirmed for the installation site.

Integration into an Agrochemical Packaging Line

The filling station can be considered within a broader packaging project covering:

• Bottle feeding and transfer.

• Closure feeding and capping.

• Sealing, where required by the packaging specification.

• Labeling and batch coding.

• Weight or vision inspection.

• Case packing and palletizing.

These are project-dependent integration options. Equipment selection, conveyor layout, accumulation requirements and control interfaces should be agreed against the required finished-product output.

What We Need to Configure Your Solution

To define the filling system and prepare a layout, provide:

• Product SDS, density and viscosity at the operating temperature.

• Foaming behavior and details of any suspended particles.

• Target fill volumes and required output for each format.

• Bottle and closure drawings, supported by physical samples.

• Cleaning requirements and product changeover frequency.

• Available floor space, utilities and downstream equipment details.

Wetted materials, seals and any explosion-protection requirements are selected through application assessment.
