Smart Liquid Feeding Control System

The Smart Liquid Feeding Control System is a centralized automation platform designed to manage feed preparation, mixing, pumping, dosing and distribution in commercial pig farms.

The system combines industrial control hardware, touchscreen operation, weighing inputs, flow measurement, sensors and programmable feeding software. It can coordinate liquid feed tanks, water tanks, pumps, agitators, feed valves, dosing devices and distribution circuits as one integrated feeding process.

Modern computer-controlled liquid feeding systems can manage multiple animal groups, feed recipes and feeding cycles while recording production data and supporting accurate feed allocation. Sensor-based feeding functions can also adjust feed delivery according to trough conditions and predefined management strategies.

The control architecture can be customized for new pig farm construction, livestock equipment upgrades and steel structure building projects according to farm size, feeding strategy, pipeline layout and required automation level.

• Centralized Feed Control: Coordinates feed preparation, mixing, pumping and distribution from one control platform.
• Recipe Management: Supports multiple feed formulations for different production stages and animal groups.
• Automatic Weighing: Connects with load cells to monitor ingredient, water and mixed-feed quantities.
• Flow Monitoring: Compatible electromagnetic or other suitable flow measurement can monitor outgoing liquid feed or water.
• Sensor Feeding: Trough sensors can be used to evaluate feed availability and optimize subsequent feeding quantities.
• Variable Pump Control: Compatible frequency converters can adjust pump speed to maintain stable flow and reduce excessive pipeline pressure.
• Automatic Valve Management: Controls feed valves, water valves and routing valves according to the programmed feeding sequence.
• Data Recording: Stores feeding events, recipe information, consumption data, alarms and operating records according to software configuration.
• Remote Access: Compatible systems can provide real-time farm data and operating access through networked computers, tablets or mobile devices.
• User Access Management: Different operator permissions can be configured for farm staff, managers and service personnel.
• Expandable Architecture: Hardware and software modules can be expanded as the livestock project grows.
• Farm-Specific Programming: Feeding logic, recipes, alarm thresholds and system interfaces can be customized according to project requirements.

• Industrial Controller / PLC: Executes the programmed liquid feeding sequences and processes sensor signals.
• Touchscreen HMI: Provides graphical access to recipes, tank status, feeding groups, alarms and system settings.
• Control Cabinet: Houses power supplies, relays, contactors, variable-frequency drives, communication modules and protective devices.
• Load Cell Inputs: Receive weighing signals from mixing tanks, water tanks or ingredient storage vessels.
• Flow Meter Interface: Measures liquid feed or water flow independently of tank weighing where required.
• Level and Trough Sensors: Monitor ingredient availability, tank levels and feed conditions at animal feeding points.
• Pump Control Module: Starts, stops and regulates liquid feed pumps according to the feeding process.
• Valve Control Module: Operates automatic feed, water and routing valves.
• Communication Interface: Connects local controllers, remote terminals and farm management systems.
• Alarm and Safety Module: Monitors equipment faults, abnormal process conditions and selected system limits.

The operator creates or selects a feed recipe for the required animal group. The controller then calculates the required quantities of ingredients and water according to the programmed ration, animal numbers and feeding curve.

Ingredient conveyors, pumps or dosing devices are activated in sequence. Load cells, flow meters and other sensors provide feedback so that the controller can monitor actual quantities during preparation.

After mixing is completed, the system starts the liquid feed pump and opens the appropriate distribution valves. Feed is delivered through the selected pipeline circuit to the required feeding points.

Suitable variable-flow control can regulate pump speed according to pipeline conditions, helping maintain controlled feed velocity and reducing excessive pressure at nearby valves.

Where trough sensors are installed, the controller can evaluate remaining feed and modify future feed quantities according to the selected sensor-feeding strategy.

At the end of the feeding cycle, the controller can initiate pipeline rinsing, tank cleaning or residue-free feeding sequences where these functions are included in the project.

Control Cabinet Location: Install the main control equipment in a dry and accessible technical area protected from direct washing, excessive humidity and corrosive farm gases wherever possible.

Field Wiring: Connect load cells, sensors, flow meters, pumps, agitators and valves according to the approved electrical drawings. Power and signal cables should be routed separately where required to reduce electrical interference.

Network Setup: Communication between local control panels, remote terminals and farm management equipment should be tested before commissioning.

Process Calibration: Load cells, flow meters and dosing devices should be calibrated before normal production. Feeding quantities should be verified against actual farm requirements.

Software Commissioning: Configure animal groups, recipes, feeding curves, valve assignments, pump settings, alarm thresholds and cleaning sequences according to the project design.

Data Backup: Feed recipes, system parameters and production records should be backed up according to the farm management procedure.

Routine Maintenance: Inspect electrical terminals, touchscreen operation, communication modules, sensors, weighing signals and alarm functions at scheduled intervals. Software and system parameters should only be modified by authorized personnel.

In a commercial finishing farm, the controller can manage several feed recipes for different pig weight groups. Ingredient quantities are weighed into the mixing tank, mixed automatically and then distributed through programmed valves to the required houses.

For sow production, sensor-based feeding can be incorporated to evaluate trough conditions and adjust future feed allocation. Remote access can also allow authorized personnel to review feeding data and make permitted corrections directly from the livestock house.

For larger integrated farms, the control system can be expanded to manage multiple tanks, pumps and pipeline circuits while recording feed consumption, alarms and operating history for centralized production management.
