Pull-out Type Broiler Cage-semi automatic bird harvesting

1. PAINPOINT DRIVEN OPENING

Managing the endofcycle process for broilers is a critical bottleneck with significant financial implications. Manual harvesting is laborintensive, stressful on birds, and poses consistent challenges to both operational efficiency and animal welfare. Are you facing these issues?

High Labor Costs & Inconsistency: Manual catching crews are expensive, difficult to schedule, and their performance varies greatly, leading to extended downtime between flocks.
Elevated Bird Stress & Condemnation Rates: The process of manually entering cages, handling birds, and passing them through the house increases panic, injury, and deadonarrival rates, directly impacting your revenue.
Worker Fatigue & Safety Risks: Repetitive bending, lifting in a dusty environment, and handling live animals contribute to high worker turnover and potential compensation claims.
Extended Downtime for Sanitation: A prolonged harvest delays the critical cleaning and disinfection phase, reducing the number of cycles you can run per year.
Inconsistent Bird Weights: Stress during manual harvest can lead to uneven weight loss, affecting your yield uniformity and meeting processor contracts.

If these challenges are impacting your bottom line, a mechanized approach to bird removal warrants serious consideration.

2. PRODUCT OVERVIEW: Pullout Type Broiler Cage with SemiAutomatic Bird Harvesting

This system is a tiered cage designed specifically for broiler production that integrates a mechanized harvesting function. The core design principle allows entire cage tiers to be partially extended from the house structure, positioning birds directly adjacent to an external collection conveyor.

Operational Workflow:
1. Feed Withdrawal & Preparation: Following standard feed withdrawal protocols, the internal cage environment is prepared.
2. System Activation & Tier Extension: Operators activate the semiautomatic system from a central control point. Selected cage tiers sequentially unlock and slide outward on heavyduty rails.
3. Guided Bird Movement: As the tier extends, gentle sloping floors and strategically placed popholes guide birds toward the open side of the unit.
4. Controlled Transfer: Workers stationed at the external collection point gently guide birds from the cage edge onto a waiting conveyor belt system that transports them to the loading module.
5. System Reset: Once empty, the tier is retracted back into its housing position, locking securely for subsequent washing.

Application Scope & Limitations:
Scope: Optimized for largescale commercial broiler operations (>50,000 bird capacity) seeking to reduce labor dependency and improve harvest consistency. Ideal for new construction or comprehensive retrofit projects.
Limitations: Requires a compatible house design with adequate side access for the extending tiers and conveyor installation. The initial capital investment is higher than manual systems or static cages.

3. CORE FEATURES

Modular Tier Extension System | Technical Basis: Linear rail guidance with centralized hydraulic/pneumatic actuation | Operational Benefit: Enables sequential access to all birds without workers entering the cage stack | ROI Impact: Reduces required harvesting personnel by up to 60%, cutting direct labor costs per cycle.

LowStress Bird Guidance Design | Technical Basis: Graduated floor slope (<12 degrees) and controlled pophole sizing | Operational Benefit: Encourages natural bird movement toward light/air at harvest point, minimizing panic | ROI Impact: Field data shows reductions in pretransport mortality by up to 0.15% and bruising/condemnation rates by an estimated 0.3%, preserving yield value.

Centralized Control Panel | Technical Basis: Programmable Logic Controller (PLC) with manual override | Operational Benefit: Allows one supervisor to manage the sequence of tier extension from a single point | ROI Impact: Improves process control and reduces coordination errors, shortening total harvest time by an estimated 3040%.

HeavyDuty Galvanized Construction | Technical Basis: Hotdip galvanized steel wire and structural components | Operational Benefit: Withstands repeated washdowns with highpressure chemicals and constant mechanical operation | ROI Impact: Extends equipment service life beyond standard coatings, reducing longterm capital replacement costs.

Integrated Waste Management Tray System | Technical Basis: Removable trays beneath each tier aligned with pullout motion | Operational Benefit: Manure can be partially cleared prior to or after harvest without interfering with the process | ROI Impact: Contributes to a drier inhouse environment during catch and speeds up postharvest cleanout.

Safety Interlock System | Technical Basis: Physical and sensorbased locks prevent unintended movement during operation or housing phases | Operational Benefit: Protects both personnel working on the system and ensures cage stability during production cycles | ROI Impact Mitigates risk of catastrophic equipment failure or workplace injuryrelated downtime.

6. APPLICATION SCENARIOS

LargeScale Integrator Retrofit Project

Challenge: A major integrator faced volatile labor markets and inconsistent harvest times across its older farms using static cages combined with manual catching crews averaging over five hours per house.
Solution: Implementation of our Pullout Type Broiler Cagesemi automatic bird harvesting system across six houses as part of a scheduled renovation cycle.
Results: Postimplementation data showed average harvest time stabilized at two hours fifteen minutes per house using their own trained staff instead of contract crews—a predictable cost—and allowed sanitation crews earlier access.

HighDensity New Build Facility

Challenge: An investor building a new greenfield facility needed maximum throughput cycles per year but was concerned about local labor availability for intensive manual tasks like harvesting.
Solution: The new facility was designed around our Pullout Type Broiler Cagesemi automatic bird harvesting system as its core housing technology from inception.
Results: The facility achieved its target of seven full cycles in its first year—a goal considered unattainable with manual methods due to downtime constraints—and reported superior flock uniformity at delivery attributed partly to reduced endcycle stress.

Plant Manager Seeking Process Control

Challenge: A plant manager struggled with variable yields due to inconsistent handling during catch days between different contract catching teams.
Solution: Adoption of this semiautomatic system brought key parts of this final stage under direct management control.
Results: They achieved more uniform bird weights delivered within processor specifications while also reducing worker compensation claims related back injuries associated traditional methods.
