Cream separators

1. Scope and Applicability

This PCR covers manufacture of complete machines whose principal function is separation of cream from milk: manual, small electric and industrial bowl/disc equipment. Actual Janschitz manual and electric configurations counter an all-industrial stainless-skid assumption; H7C is industrial architecture evidence, not a category average. Exclude generic laboratory or mineral centrifuges, entire dairy plants, independently supplied parts and downstream milk-separation services. Record actual technology and material by delivered configuration; throughput, fat ratio and service life are not factory manufacturing factors.

2. Product Category Identity

3. Reference Flow

Field	Value
What	Manufacture deliverable cream-separation equipment
How much	1 kg net mass of accepted same-configuration machines; collection per accepted finished machine
How well	Conform to actual drawing, sanitary contact, drive and factory acceptance specifications; no category performance presumed
How long or cycle	One declared manufacture/acceptance period; no assumed service lifetime
reference_flow_link	finished_separator

Field	Value
Reference amount	1

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	model; same configuration; manual/electric; bowl/discs; material/contact state; make/buy; included motor, drive, controls, frame, sanitary modules; net mass/factory fill; acceptance; site/period

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.
contained_assay	physical material and species records	Mass	kg	Use own measured assay and wet/dry basis for each species; do not apply material assays to electricity or transport services.
utility_units	utility records	Energy/volume	kWh; MJ; m3	Retain raw meter units/conditions; convert with documented calorific value, density or enthalpy; rated power cannot substitute consumed electricity.

5. System Boundary

rule_id	Applies to	Rule	source_ids
factory_gate	all processes	Collect actual manufacture to accepted manufacturer gate including scrap, rework, factory lubrication and qualification. Operation at the dairy, installation, replacement and end of life are separate downstream stages.
make_buy	BOM interfaces	For every bowl, disc, drive, bearing, hygienic connection, housing, skid and control item record make/buy, supplied state, actual alloy/polymer/compound and included operations. Charge either upstream finished component plus local assembly, or raw input plus actual manufacture; never both.	tetrapak-h7c-2025; janschitz-separator-architectures
route_gate	actual route	Casting, forging, heat treatment, machining, forming, welding, passivation, anodizing, coating and polymer molding activate only on actual supplier/site route evidence. Product material does not prove its fabrication route; declared optional cards are not default recipes.	jrc-smitheries-foundries-2024; jrc-fabricated-metals-2020
extensions	actual exchanges	Anchor cards are conditional examples. Add each actual grade, chemical, gas, waste, utility and emission as its own specific exchange, including super-duplex, shaft steel, seals, belt, sensors, auxiliary box and oil if independently supplied. Missing identity is an explicit gap, never exclusion or zero.
upstream	external interfaces	Match provider geography, period, supply state and completed processes; add input transport and external waste treatment links. Cancel paired internal material/utility transfers without erasing their operating burdens. Incomplete upstream links prohibit an undisclosed complete cradle-to-gate claim.

Boundary Abstraction

Field	Value
declared_starting_condition	Actual supplied material or component with declared completed operations
starting_condition_role	Foreground supplier-state boundary
product_classification_scope	Complete cream-separation equipment; classification leaf is not fabrication evidence
recursive_input_rule	Bought same-category unfinished machine charged upstream once, subsequent local operations separate; paired internal transfers cancel
upstream_dataset_requirement	Match actual grade, formulation, state, technology, geography, period and supply interface; disclose gaps
disclosure	Delivered configuration, BOM, make/buy, test scope, stocks, allocation, uncertainty and exclusions

Make/buy and architecture matrix

Assembly	Rule
Bowl and discs	Bought finished versus actual blank processing; aluminium, duplex, super-duplex and stainless grades separate; do not infer forging from material
Manual drive or motor	Actual configuration only; embedded lubrication/electrical controls charged once; manual machine without motor has no motor input
Sanitary components and housing	Container, outlets, seals, connections, cast/molded part by drawing/material declaration; generic plastic/elastomer does not establish exact compound
Skid and control options	Actual supplied frame, sensors, PLC, auxiliary box and service kit; verify component inclusion and exclude unsupplied options

6. Process Inventory Structure

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
product_separation	configuration groups	Separate manual, small electric and industrial configurations before allocation. Allocate shared measured production burdens by documented causal machine time, heat demand or work orders; retain driver, total, recipient and uncertainty. Do not average across configurations.
scrap	external recovered material	Record actual scrap destination and retained oil/metal content. No automatic avoided virgin-metal credit; disclose any recycling model separately. Internal return is a paired transfer, not an external coproduct.
test_products	factory test outputs	Discarded test milk and wastewater are wastes. Useful test cream or skim milk requires measured quantity, quality, destination and causal separation before any coproduct allocation; no default sale, yield or dairy-process allocation.

cp_water	all applicable processes	measured exchange	foreground_record	water meter; input moisture; stock; evaporation; discharge; reaction; paired returns; assay; accepted units	Measure external water and every actual moisture/output term with paired circulation records; convert volume using measured density and conditions.	kg	each batch or interval	same declared production period	same configuration/site/process	attributable water / accepted machines	Calibration, matched samples, work orders, stocks, uncertainty and acceptance evidence
cp_waste	all applicable processes	measured exchange	foreground_record	waste lot; destination; measured mass; moisture; own metal/species assay; stock; paired return; accepted units	Use calibrated weighing and representative matched sampling for each stream; keep actual treatment and recycling destinations separate.	kg	each batch or interval	same declared production period	same configuration/site/process	attributable waste / accepted machines	Calibration, matched samples, work orders, stocks, uncertainty and acceptance evidence
cp_solvent	all applicable processes	measured exchange	foreground_record	solvent identity; fresh mass; concentration; opening/closing stock; recovered; retained; captured assay; destroyed; air/non-air releases; accepted units	Measure species-resolved solvent inventory and discharge/capture samples; retain air-flow integration and destruction reaction evidence separately.	kg	each batch or interval	same declared production period	same configuration/site/process	attributable solvent / accepted machines	Calibration, matched samples, work orders, stocks, uncertainty and acceptance evidence

cp_purchased_heat	utilities	purchased steam net delivered heat	foreground_record	delivered steam mass kg; own steam specific enthalpy MJ/kg; pressure; temperature; quality; separately measured condensate return mass kg; own return enthalpy MJ/kg; common enthalpy reference; calibrated heat meter; period; configuration; accepted count	Measure delivered steam mass and its own specific enthalpy at actual pressure, temperature and quality; subtract separately measured condensate-return mass times its own return enthalpy on the SAME enthalpy reference to obtain net delivered MJ. Alternatively use a calibrated net heat meter with return treatment recorded. Keep the same site period, accepted output and configuration; no assumed enthalpy, kg-to-MJ equivalence or simultaneous own-boiler fuel charge.	MJ	each interval	same declared production period	same configuration/site/process	attributable purchased heat / accepted machines	Calibrated mass/heat meters, state measurements, enthalpy derivation, return ledger and uncertainty

For the same configuration/period, Q is attributable period exchange including reject and rework burdens, N is accepted count, and M is summed calibrated accepted net mass/N. Obtain q_item=Q/N, then normalize_mass gives q_ref=Q/summed accepted net mass. Weigh actual shipped components and factory-retained fill, excluding drained test media, packaging and rejected mass; never average configurations.

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

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
configuration	all records	Same configuration, period, denominator and process coverage; unknown never becomes zero	Acceptance, BOM, work orders
traceable_balance	physical streams	Trace mass/species assays to actual samples and stocks; combined uncertainty guides investigation	Calibration, assays, transfer ledger
source_limit	methodology and providers	Product leaflet proves architecture, not every factory route or provider identity; supplement actual process/recipe records	Provider interface, route cards

9. Validation Rules

rule_id	Applies to	Rule	source_ids
identity	reference product and BOM	Verify one complete accepted cream-separation machine, actual configuration, calibrated net mass, delivered fill, manual/electric architecture and BOM make/buy interfaces. Exclude packaging, rejected machines and downstream milk throughput from denominator.
physical_mass	physical material streams	For the same configuration and period reconcile external inputs plus opening stock plus reaction addition with accepted product, rejects, scraps, slag/dross, sludge, wastewater, releases and closing stock. Pair each internal return by transfer id and quantity; no double counted recycle.
contained_species	contained metal and chemical species records	For each actual Al, Fe, Cr, Ni, Mo, carbon, fat or bath species, multiply each term by that term's OWN matched measured assay and wet/dry basis. Include accepted product, scrap, scale, dross, sludge, wastewater and emissions plus stocks, reaction sources/sinks and paired returns. Gross alloy mass is never contained-element mass; nominal feed alloy assay cannot stand for residue/product assay.
water_closure	physical water and moisture records	Reconcile supplied water and input moisture plus opening stock and reaction formation against product/fill moisture, wet scrap/sludge, liquid effluent, evaporation, reaction consumption and closing stock. Pair recirculation, rinses and condensate returns; Each wet input, product/fill, scrap, sludge, wastewater and opening/closing stock term uses its OWN measured moisture or water fraction, density where volume is converted, and matched wet/dry basis; gross wastewater is not its contained water.
solvent_closure	actual solvent-bearing material records	For each actual solvent reconcile fresh plus opening stock and generation against retained product, recovered external solvent, closing stock, air release, captured-media solvent, wastewater solvent and actual destruction/reaction products. Capture is transfer, not destruction; non-air residuals cannot default to air. Unexplained balance residual must not automatically be assigned to air, including unmeasured losses; investigate it using actual combined measurement, sampling, stock and allocation uncertainty.
utilities_closure	utility energy and service-media records	Reconcile all process loads and unassigned residual services to same-period site meters in matching units: purchased imports plus actual site generation plus opening storage/returns equal attributed loads plus exports, losses and closing storage. Allocate only unassigned residual; never add whole-factory imports atop submeters. Investigate negative residuals using period, unit and combined uncertainty; never clip.
emission_species	actual combustion and release species records	Fossil carbon balance does not determine CO or NOx. Keep measured NO, NO2 and NOx reported as NO2-equivalent distinct, with actual reporting convention and molecular-mass conversion; never treat an aggregate convention as an individual-species identity. Each claimed emission needs own measured species, actual compartment and sampling/flow integration; characterize wastewater species without treating external treatment as direct elementary discharge.
closure_uncertainty	physical balance residuals	Investigate closure residuals against actual combined scale/meter, sampling/assay, stock, reaction and allocation uncertainty and record corrective evidence. No universal tolerance, invented loss, default yield or balancing plug is permitted. Distinguish not_applicable with absence evidence, measured zero and unknown.
provider	external flow links	Verify exact flow type, reference property, unit, physical/chemical state and supply interface before binding any UUID; incompatible generic centrifuge, battery separator scrap or source-specific generated power cannot substitute. Resolve candidate identity and quantitative gaps before publication.
