Liquid Feeding Controller

The Liquid Feeding Controller is the central automation and management unit for computer-controlled liquid feeding systems used in commercial pig production. It coordinates ingredient dosing, mixing, weighing, pumping, feed distribution, valve operation, rinsing and process monitoring from one integrated control platform.

The controller can manage different feed recipes and feeding curves for sows, piglets, growers and finishing pigs. Ingredients are prepared according to programmed formulations, mixed into a pumpable feed and distributed in controlled quantities to individual feeding valves or animal groups.

Reference liquid-feeding systems allow the controller to compare target and actual feed quantities, automatically correct valve delivery, manage multiple recipes and record farm production data. Graphical interfaces simplify operation by displaying system status, recipes, feed curves, alarms and process information in an easy-to-read format.

The controller can be integrated into new pig farm construction, feed kitchens, steel structure livestock buildings and existing liquid feeding system modernization projects according to farm size and automation requirements.

• Automatic Liquid Feeding Control: Coordinates ingredient dosing, mixing, pumping and distribution without continuous manual intervention.
• Recipe Management: Multiple liquid feed formulations can be stored and assigned to different animal groups or production stages.
• Feed Curve Management: Feeding quantities can be adjusted according to animal age, production stage and programmed nutritional strategy.
• Individual Valve Control: Compatible systems can control individual feed valves and automatically correct delivered quantities.
• Target / Actual Comparison: Compares programmed feed quantities with measured delivery data to improve process control.
• Weighing Integration: Can process information from mixing tank load cells, rinse-water tank load cells and other compatible weighing equipment.
• Process Visualization: Touchscreen HMI displays tanks, pumps, valves, pipelines and active process steps graphically.
• Automatic Cleaning Control: Can coordinate pipeline rinsing, tank cleaning and residue-free feeding cycles according to system configuration.
• Alarm Management: Detects defined operating faults and can provide local or remote alarm notifications.
• Production Data Recording: Feeding data can be recorded for analysis of feed consumption and farm management.
• Remote Management: Compatible systems can support remote monitoring, data transfer and backup through farm-management software.
• Modular Expansion: I/O, communication modules and controlled equipment can be configured according to project requirements.

• Touchscreen HMI: Provides graphical process visualization, parameter entry, recipe management and alarm information.
• PLC / Industrial Controller: Executes programmed feeding sequences, calculations and interlocking logic.
• Digital Input Modules: Receive signals from level sensors, position switches, pressure switches and other field devices.
• Digital Output Modules: Operate solenoid valves, pumps, motors and related actuators.
• Analog Input Modules: Receive weight, pressure, flow or other proportional measurement signals.
• Communication Modules: Connect controllers, farm computers, remote I/O and compatible external equipment.
• Power Supply: Provides stable control voltage to automation components.
• Motor Protection Components: Circuit breakers, contactors, overload relays and optional variable-frequency drives protect connected equipment.
• Emergency Stop Circuit: Provides rapid shutdown of selected feeding equipment when required.
• Control Cabinet: Protects electrical components and provides organized wiring for field equipment.

At the beginning of a feeding cycle, the controller identifies the programmed animal group, recipe, feed curve and required quantity. It then activates the corresponding ingredient valves, augers, pumps or dosing devices.

Solid and liquid ingredients are introduced into the mixing tank according to programmed target quantities. Load cells or other measuring devices provide continuous feedback so that ingredient dosing can be stopped when the required amount is reached.

After mixing, the controller starts the liquid feed pump and operates the required distribution valves in sequence. Feed is transported through the pipeline and delivered to the corresponding pens, feeding stations or animal groups.

Compatible controllers can compare the set quantity with the actual delivered amount and automatically compensate for deviations during subsequent feeding cycles.

After feed distribution, the controller can initiate pipeline rinsing or residue-free cleaning functions, manage recovered rinse water and record process data for farm analysis.

Controller Location: Install the touchscreen controller and main automation cabinet in a dry technical area or corridor wherever practical, away from direct washing, excessive humidity and aggressive barn gases.

Electrical Installation: Power, motor, sensor and communication wiring should be separated and installed according to local electrical regulations and the approved project drawings.

Field Device Connection: Confirm correct wiring for load cells, level sensors, feed valves, pumps, mixers, pressure sensors and other controlled devices before commissioning.

Software Configuration: Enter tank capacities, feed ingredients, recipes, feed curves, valve assignments, feeding times and cleaning parameters according to the actual farm layout.

Commissioning: Test each motor, valve and sensor individually before running a complete automatic feeding cycle. Verify weighing calibration and emergency stop functions.

Data Backup: Periodic backup of recipes, system settings and production data is recommended where supported by the selected control platform.

Routine Maintenance: Keep the cabinet ventilation system clean, inspect terminals and wiring, test alarms and emergency stops, and verify sensor signals and weighing accuracy at scheduled intervals.

In a commercial finishing farm, the controller can manage ingredient dosing into a weighed mixing tank, operate the mixer and pump, and distribute different recipes through multiple feed valves according to programmed feeding curves.

For sow and piglet production, a single control platform can be configured to manage several production groups with different recipes, feed quantities and feeding times.

In residue-free feeding projects, the controller can coordinate feed transport, pipeline flushing, rinse-water recovery and subsequent recipe preparation to improve system hygiene and feeding efficiency.

Final system design should be based on animal numbers, number of recipes, tank configuration, pipeline layout, valve quantity, required feed accuracy and preferred farm-management functions.
