# Automatic poultry dry-feed distribution equipment manufacture

## 1. Scope and Applicability

This PCR covers foreground manufacture of new complete automatic poultry dry-feed conveying and distribution equipment, specifically configured auger/tube/pan feeding lines and chain/trough feeding circuits. Record these configurations separately. A complete equipment set can be shipped as traceable sections for later site assembly, provided all specified feeding, drive, control and equipment-support components are delivered and factory acceptance limitations are disclosed. A partial spare-part shipment is not the reference product.

The semantic boundary is narrower than CPC 44194. Exclude drinking systems, nests and egg collection, manure removal, house ventilation/heating, incubators/brooders, slaughter/processing machinery and feed milling/mixing. Exclude external bulk storage silos, upstream transfer conveyors and house fabric unless a separately defined equipment reference includes them; this reference starts at the feeding equipment inlet. Exclude farm installation services, flock feeding, feed production/consumption, bird growth, mortality, manure emissions, farm cleaning/disinfection, maintenance and end of life. No per-bird productivity or lifespan equivalence is claimed.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Manufacture the stated complete automatic poultry dry-feed distribution equipment |
| How much | 1 kg net accepted complete equipment; per-machine collection converted with measured M |
| How well | Meets documented configured completeness, dimensional, drive, sensor/interlock and guarding factory acceptance criteria; site-only tests are disclosed |
| How long or cycle | One manufacture and factory acceptance cycle; no assumed farm life |
| reference_flow_link | finished_machine |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Poultry-keeping machinery `f1ec443d-7549-4c44-b840-802dc1d73c5c` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | manufacturer/model; order/serial and configuration revision; poultry dry-feed function; auger/pan or chain/trough architecture; line/circuit length and shape; tube/trough cross-section and coating; feed-point count, pan geometry/material and nylon grade; hopper/extension; auger or chain link specification; drive rating, phase, reduction and completeness; corner wheels and bearings; fixed or suspended support, winch/rope/guards; dedicated sensor/controller and wiring; supplier assembly boundaries; delivered sectional quantities; net M and packing tare; excluded silo/building/shared systems; factory acceptance and site-test gaps; site/period/gates; outsourcing and upstream coverage |

Declare every qualifier in metadata or reference-flow comments. M includes all delivered equipment components of the same configured set, including equipment supports, and excludes transport supports, packaging and test feed. For sectional delivery, retain calibrated net weighing and item-level completeness records for the whole set; an unverified catalog mass or feed contents is not M. Tube length, pan count, bird capacity and motor kW are not mass conversion factors.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | M = accepted net mass of one complete machine of the same configuration in kg; collect using cp_mass. |
| `meter_conversion` | utilities and length records | Mass; Net calorific value | kg; MJ | Use the row reference property. Verified energy unit-group conversion is 3.6 MJ/kWh. A length-based component record requires measured construction-specific mass per length; water volume requires measured density/reference conditions. A flow-property meanValue is not a generic density. |


## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Purchased specified sheet/strip/resin and finished components received at the equipment manufacturing site |
| starting_condition_role | foreground manufacturing module |
| product_classification_scope | Configured automatic poultry dry-feed equipment only; broader poultry machinery reference is qualified to this scope |
| recursive_input_rule | Record a bought-in same-category feeding module once with supplier completeness and property; count only added foreground work and exclude duplicate constituent purchases |
| upstream_dataset_requirement | Match supplied metal finish, polymer grade, component completeness, geography, period and reference property; disclose missing supplier links and any reviewed proxies |
| disclosure | State factory receipt-to-dispatch gates, in-house versus outsourced routes, transport coverage, utilities and missing upstream stages. This foreground module alone is not complete cradle-to-gate |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `boundary_actual` | all processes | Include actual operations, rejects/rework and factory tests attributable to the delivered configuration. Bought-in assemblies bypass their stock/molding operations; unlinked supplier manufacture and outsourcing remain explicit gaps. |  |
| `boundary_complete` | all inventory rows | Reconcile the entire configured BOM. Add omitted actual pigments, mold-release formulation, process lubricant, fasteners, legs, anti-roost wire, drive oil, guards, terminals, test-feed formulation, packaging and wastes as separate specific atomic cards. Unknown quantities are not zero; this list is not proof of absence. |  |
| `boundary_farm` | reference product | Separate manufacturing from poultry operation and installed farm services. No feed intake, animal yield or farm manure emission belongs to this equipment manufacturing reference. |  |


## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| `metal` | Sheet fabrication and auger forming | conditional | These operations actually occur at the reporting site. | foreground | one accepted configured machine, normalized using M |
| `molding` | Polymer part molding | conditional | Declared polymer parts are molded in the foreground; bought-in finished parts bypass molding. | foreground | one accepted configured machine, normalized using M |
| `mechanical` | Feed-distribution mechanical assembly | required | Each complete feeding-equipment configuration. | foreground | one accepted configured machine, normalized using M |
| `controls` | Dedicated controls and wiring integration | required | Each automatic feeding-equipment configuration; sensor/control architecture must be stated. | foreground | one accepted configured machine, normalized using M |
| `acceptance` | Factory acceptance and completeness reconciliation | required | Every accepted complete equipment set. | foreground | one accepted configured machine, normalized using M |
| `packing` | Dispatch packaging | conditional | Packaging crosses the defined factory dispatch gate. | foreground | one accepted configured machine, normalized using M |

Actual metal fabrication and molding feed mechanical assembly → dedicated controls → factory acceptance → conditional dispatch packaging. Finished purchased parts enter at their integration stage. These are equipment manufacture operations, not farm feed conveyance. Source links support configuration or candidate technique only; all amounts and actual route activation come from linked foreground protocols. No direct elementary release is assumed from product descriptions; add each demonstrated manufacturing emission by substance and environmental medium with measurement evidence.

### Process: Sheet fabrication and auger forming (`metal`)

Cut, punch and fold specified supplied galvanized sheet into hoppers or troughs; form a conveying spiral from specified strip only when made in-house. Do not assume tube production, galvanizing, welding or heat treatment at the assembly site. Finished purchased hoppers, troughs and augers bypass their corresponding stock operations. Internal parts transferred to assembly are not new purchases.

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `allocation_orders` | shared operations | Separate orders by line architecture and exact layout/BOM. Prefer directly measured stock, molding cycles and utility records. For a shared operation, collect and justify a causal order driver such as actual metered load or machine-hours, and allocate the attributable total in proportion to each order driver divided by the complete covered driver sum. Preserve all covered orders and unfinished stock; do not use unmeasured birds served as a driver. |  |
| `allocation_recovery` | regrind and waste | Reconcile internal resin regrind and metal returns without treating each circulation as fresh purchase. Exported offcuts/purge carry actual mass and destination; no automatic avoided-material credit is assigned. Separately identify any saleable co-product, first divide physical operations where possible, and review residual allocation with the collected basis. |  |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `normalize_mass` | all inventory rows | q_ref = q_item / M; q_item = exchange amount per one accepted finished machine; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

Obtain each attributable order amount from issued quantities minus returns with measured stock changes, waste/test records and documented shared-operation allocation. Divide by accepted complete sets to collect q_item, then normalize with measured same-configuration M. Include period rejects and rework in accepted-output burdens while disclosing unfinished stock. For variable net masses within one homogeneous configuration, use total attributable exchange divided by total accepted net mass with serial records. Separate unlike layouts rather than blending short and long lines under an invented standard line.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `quality_configuration` | all rows | Trace full layout, feed-point count, delivered sections, polymer grades, metal coatings and module completeness. Retain unresolved supplier material specifications as gaps rather than assuming a universal recipe. | drawings, BOM and supplier specifications |
| `quality_balance` | stock and utilities | Reconcile metal, polymer, purchased assemblies, accepted net mass, regrind, rejects, waste and stock change. Explain uncertainty and measured length/density conversions. Account for drive/control tests without counting farm power. | weighing, issues/returns, meters and waste transfer |
| `quality_coverage` | all processes | State site and continuous period, provider links and outsourced gates. Establish configuration-specific QA limits from measured records; these product descriptions provide no manufacturing intensity or net equipment mass range. Missing important amounts remain pending collection. | order coverage, calibration, boundary and gap list |


## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `validate_reference` | reference product | Require complete configured automatic dry-feed equipment, positive measured M and all declared delivered sections/supports. Reject incomplete spares and other poultry-keeping functions. Disclose unperformed site tests and exclude feed/packaging from net equipment mass. |  |
| `validate_identity` | all inventory rows | Require one atomic physical exchange and matching public flow identity, property, unit, polymer grade, metal finish and component completeness. Do not substitute generic resin for a finished part, galvanizing for sheet stock, or energy-property cable for cable mass. Resolve absent identities before releasing a fully linked dataset. |  |
| `validate_collection` | all inventory rows | Verify linked protocols, q_item/M normalization, same layout denominator, stock/rework allocation and utility meter coverage. Purchased complete modules and internal molding/fabrication transfers are not double counted; extend the inventory to every actual omitted atomic input/output. |  |
| `validate_release` | measured environmental releases | Add demonstrated manufacturing releases individually with substance, fossil/biogenic origin where relevant, receiving medium/subcompartment and measured quantity or verified applicable factor. Treatment wastewater is a technosphere outlet; poultry manure and farm dust are outside this manufacture gate. No inferred zero for unmeasured relevant releases. |  |

| excluded_use | Per-bird feed/yield comparison; installed house-service equivalence; drinking/manure/egg/climate/incubation proxy; complete cradle-to-gate without supplier linkage |
| required_metadata | Reference qualifiers; measured M; layout and sectional delivery completeness; supplier material grades and boundaries; factory/site-test evidence; actual route, period/gates, collection/allocation and background links |
| required_quality_disclosure | Missing identities/amounts, measurement uncertainty, inactive routes, untested site functions, source date/scope, outsourcing and upstream gaps |
