Twin-Tank Liquid Feed Mixing System

The Twin-Tank Liquid Feed Mixing System is a high-capacity automatic feeding solution designed for commercial pig farms that require rapid preparation and distribution of multiple liquid feed recipes.

The system uses two mixing tanks that can operate in coordinated cycles. While liquid feed is being prepared in one tank, a completed batch can be distributed from the second tank. This parallel operating concept reduces waiting time between batches and provides high feeding performance for large sow, piglet and finishing units.

Dry and liquid feed ingredients are weighed, mixed with water or suitable liquid components and processed into a pumpable homogeneous ration. The prepared feed is then transported through ring lines or branch lines and accurately dispensed through individual feed valves.

The system can be engineered as part of a complete feed kitchen for new pig farm construction or integrated into suitable existing livestock buildings. Tank capacity, weighing equipment, pumps, agitators, pipelines, valves, cleaning equipment and control functions are customizable according to project requirements.

• Parallel Mixing and Feeding: One tank can prepare a new batch while liquid feed from the second tank is being distributed.
• High Feeding Capacity: The two-tank operating concept is suitable for large pig populations and projects requiring multiple feeding cycles.
• Flexible Recipe Management: Different dry and liquid ingredients can be combined according to feeding stage, animal group and nutritional program.
• Accurate Ingredient Weighing: Compatible load-cell weighing systems can measure feed components and mixed feed according to programmed recipes.
• Homogeneous Mixing: Motor-driven agitators keep solid and liquid components uniformly mixed before and during distribution.
• Automatic Feed Distribution: Pumps and controlled feed valves deliver calculated portions to individual pens or feeding groups.
• Multi-Phase Feeding: Suitable control systems can prepare different recipes for piglets, growers, finishers or breeding animals.
• By-Product Utilization: Suitable configurations can incorporate liquid ingredients such as whey and compatible food-industry by-products.
• Residue-Free Feeding Options: Ring-line, branch-line and compatible flushing concepts can be selected according to hygiene requirements.
• Automated Hygiene Functions: Tank and pipeline cleaning can be integrated into the control sequence.
• Modular Expansion: Pumps, valves, ingredient storage and feeding circuits can be configured for small or large production units.
• Farm Management Integration: Feeding data, recipes and operating parameters can be managed through compatible computerized control systems.

• Mixing Tank A: Weighs and mixes dry and liquid feed components into a homogeneous pumpable ration.
• Mixing Tank B: Alternates with the first tank to support simultaneous preparation and feed distribution.
• Agitator Assemblies: Motor-driven mixers maintain uniform distribution of solids within the liquid feed.
• Weighing System: Load cells or suitable weighing modules measure ingredients and tank contents.
• Feed Pumps: Transfer prepared liquid feed from the mixing tanks into the distribution network.
• Ingredient Inlets: Allow water, dry feed, minerals, liquid components and other suitable ingredients to enter the mixing tanks.
• Feed Distribution Manifold: Directs liquid feed to selected feeding circuits.
• Feed Valves: Automatically dispense programmed quantities into troughs or feeding locations.
• Ring or Branch Pipelines: Transport liquid feed from the feed kitchen to the livestock houses.
• Rinse Water System: Optional fresh-water or weighed rinse-water equipment supports cleaning and residue control.
• Cleaning Devices: Tank sprinklers, flushing circuits or other hygiene components can be integrated.
• Sensors: Level, weight, pressure, flow and trough sensors can be included according to automation requirements.
• Control Cabinet and Feeding Computer: Coordinates ingredient dosing, mixing, pumping, valve operation, feeding schedules and cleaning cycles.

The feeding computer selects the required recipe and calculates the quantities of water, dry feed and other approved ingredients required for the next batch.

Ingredients are transferred into the first weighing and mixing tank. The agitator operates according to the programmed sequence to create a homogeneous liquid feed mixture. Once the target recipe and batch weight have been reached, the prepared feed becomes available for distribution.

The feed pump transports the mixture through the selected feed circuit. Automatic feed valves open according to the feeding program and dispense the calculated quantity to individual pens, animal groups or troughs.

While feed is being distributed from one tank, the second tank can simultaneously prepare the next batch. The tanks alternate between preparation and distribution, significantly reducing idle time when several recipes or large numbers of animals must be supplied.

After feeding, optional rinsing and cleaning sequences can flush pipelines and clean the tank surfaces. Depending on the project design, rinse water may be recovered and used during preparation of a subsequent ration.

Feed Kitchen Planning: Determine daily feed demand, number of recipes, animal groups, feeding times, transport distances and available building space before defining tank and pump capacities.

Foundation: Mixing tanks, pumps and related equipment should be installed on a level and load-bearing concrete base designed for the operating weight of the complete system.

Tank Installation: Tanks should be positioned with adequate access for agitator service, load-cell inspection, cleaning and maintenance.

Pipeline Layout: Pipe diameter, route, elevation differences and valve positions should be engineered to maintain reliable feed transport and simplify cleaning.

Weighing Calibration: Tank load cells and ingredient weighing equipment should be calibrated after mechanical installation and before normal feeding operation.

System Commissioning: Test ingredient dosing, agitator rotation, pump direction, feed valves, sensors, recipe control and cleaning sequences before introducing feed to animals.

Daily Hygiene: Mixing tanks and feed pipelines should be cleaned according to the feeding strategy, feed ingredients and farm hygiene program.

Routine Maintenance: Periodically inspect agitators, pumps, load cells, valves, sensors, seals, pipelines and electrical components. Wear parts should be replaced according to operating conditions and preventive maintenance schedules.

In a large finishing farm, the twin-tank system can alternate between multiple feed recipes throughout the day. While one tank distributes a completed ration, the second tank prepares the following batch, allowing feeding to continue with minimal interruption.

For integrated sow, nursery and finishing projects, different recipes can be prepared for different production stages. Separate feed circuits or controlled valves distribute each ration to the designated livestock house or animal group.

Reference two-tank liquid-feeding systems can also be configured for residue-free distribution through ring lines or branch-line concepts. This helps improve feed hygiene and reduce carry-over between different recipes.

Final system engineering should be based on animal numbers, daily feed requirement, ingredient availability, dry matter content, feed transport distance, barn arrangement and required level of automation.
