Bulk loading • bottling • blending interfaces
Food manufacturing • commercial frying equipment
Equipment cleaning • wash-water supply • utility interfaces
Conceptual maps, not installation drawings. Product candidates are functional comparisons for review, not proven interchangeable replacements. No universal micron grade, yield improvement or shelf-life claim is implied.
Residual fruit solids can become bottle sediment and load a downstream filter. Treat sediment removal and residual-water management as separate acceptance questions, while preserving the intended sensory character of the oil.
Teal: filtration · Gold: verification. Conceptual treatment logic; pumps, valves and protective devices are not fully shown. Not an installation drawing.
Do not infer water-removal capacity from a particle rating. This guide does not specify bleaching or other refining treatments for virgin olive oil.
| Stage | Objective | PARSWOOD approach to evaluate |
|---|---|---|
| Feed control | Avoid overwhelming a polishing filter. | Measure residual solids after the installed separator. |
| Depth clarification | Evaluate sediment control without assuming an equivalent module. | Trial a lenticular grade with the actual oil and record pressure rise and throughput. |
| Acceptance | Preserve the product specification. | Compare moisture, appearance and sensory results before and after filtration. |
Oil category; upstream separation; suspended solids; moisture; viscosity and temperature; throughput; sensory acceptance.

A mechanically pressed oil may carry suspended seed material into storage. Set a product-specific sediment target and preserve the oil’s desired colour and flavour; a universal fine grade is not a useful starting point.
Teal: filtration · Gold: verification. Conceptual treatment logic; pumps, valves and protective devices are not fully shown. Not an installation drawing.
Confirm whether each oil is intended to remain unrefined. Changes in flavour, colour and useful constituents must be evaluated alongside clarity.
| Stage | Objective | PARSWOOD approach to evaluate |
|---|---|---|
| Bulk removal | Reduce the load reaching disposable media. | Review settling or other installed separation before adding finer media. |
| Particle control | Meet an agreed sediment specification. | Consider a compatible bag or lenticular medium and compare total batch performance. |
| Quality release | Retain the intended oil characteristics. | Use retained samples and the agreed analytical and sensory checks. |
Seed or fruit source; pressing route; batch size; residual solids; operating viscosity; intended label and quality targets.

Refining combines chemical and physical operations with distinct purposes. Filtration can separate solid treatment media or particles, but cannot be presented as a substitute for the entire refining train.
Teal: filtration · Gold: verification. Conceptual treatment logic; pumps, valves and protective devices are not fully shown. Not an installation drawing.
No verified PARSWOOD replacement for a hot bleaching-earth filter, refinery leaf filter or dewaxing system is established here. General PP elements must not be assumed suitable for these duties.
| Stage | Objective | PARSWOOD approach to evaluate |
|---|---|---|
| Identify the stream | Separate a bulk-solids duty from downstream polishing. | Review the refinery diagram and the installed filter’s specification. |
| Guard assessment | Determine whether a further stage is justified. | Obtain written materials, temperature, retention and vessel qualification before proposing an element. |
| Release | Protect the next operation. | Agree a carryover test and assess performance under the actual operating envelope. |
Upstream unit; solids identity; temperature and viscosity; flow; pressure; existing equipment; carryover limit.
No verified catalogue equivalent is established for this duty.

An accepted oil can pick up particles during storage or transfer. A final particle-control stage should address that specific risk while preserving the formulation and fitting the packing line’s flow requirement.
Teal: filtration · Gold: verification. Conceptual treatment logic; pumps, valves and protective devices are not fully shown. Not an installation drawing.
Clear oil is not evidence of sterility or absence of dissolved contaminants. Do not apply an aqueous membrane’s microbial claim to oil without application-specific validation.
| Stage | Objective | PARSWOOD approach to evaluate |
|---|---|---|
| Transfer risk | Identify likely contamination sources. | Review tanks, seals, hoses and line-changeover practices. |
| Final particles | Choose a defined retention requirement. | Evaluate a suitable bag or pleated cartridge and its seal arrangement. |
| Packing acceptance | Verify the finished product. | Record lot, element, pressure history and relevant release results. |
Oil or blend; formulation; fill rate; viscosity; particle target; line hygiene; contact time; packaging specification.

Food crumbs and fine solids accumulate during frying. Their removal is one maintenance duty; the oil’s chemical condition and suitability for continued use require separate checks.
Teal: filtration · Gold: verification. Conceptual treatment logic; pumps, valves and protective devices are not fully shown. Not an installation drawing.
No PARSWOOD hot-fryer filter equivalent has been verified. General process bags, PP cartridges and lenticular modules are not offered here as replacements for the fryer’s approved system.
| Stage | Objective | PARSWOOD approach to evaluate |
|---|---|---|
| Solid debris | Control accumulated food particles. | Retain the equipment-specific coarse capture stage. |
| Fine solids | Use media designed for the installed fryer system. | Confirm the full hot-oil operating and handling requirements. |
| Oil condition | Separate clarity from continued-use acceptance. | Use quality results rather than appearance alone for the return/discard decision. |

A high-flow cartridge does not by itself make water suitable for food contact. No liquid filter in this guide is presented as a sterile-air or steam filter.
| Stage | Objective | PARSWOOD approach to evaluate |
|---|---|---|
| Define the use | Distinguish utility and contact-water requirements. | Agree the receiving process’s water specification. |
| Particle control | Manage a measured solids burden. | Review a high-flow or pleated candidate and exact retention performance. |
| Acceptance | Check the complete treatment system. | Verify the specified chemistry and microbiological criteria where relevant. |

Candidate for clarification of conventional edible oils.
The listing explicitly includes edible oils and identifies cellulose-based sheet media with a PP support and several seal options.
Select the exact grade by trials. Obtain food-contact documentation, operating limits and evidence for any water-reduction claim; the product listing does not establish equivalent performance to another supplier’s module.
View product specifications →Candidate for suitable coarse or final particle-control duties in food oils.
The catalogue offers different media and ring constructions with nominal retention ratings.
Confirm food-contact suitability, oil compatibility, basket support, seals and viscosity-related pressure loss. A nominal rating does not establish a microbial barrier.
View product specifications →Candidate for a defined particle target in a compatible liquid.
A finer particle-control option to investigate after upstream solids loading is understood.
Request the exact grade’s efficiency test, food-contact documentation and flow data for the actual oil. Do not size from a clean-water flow figure alone.
View product specifications →Candidate for particle pretreatment in edible-oil plant water systems.
Several constructions and formats are available; identify the precise model before comparing it with an installed element.
This guide links this family for water duty only. It does not establish suitability for food-oil production, hot frying oil, air or steam.
View product specifications →Match the vessel to the selected element and hygiene requirements.
Review sealing, drainage, cleaning access, materials and the documented pressure/temperature envelope.
A housing family or stainless-steel description is not proof of hygienic design or food-contact compliance for a particular installation.
View product specifications →Request the exact grade’s retention evidence, food-contact declaration, materials and seal details, cleaning instructions, and pressure/temperature limits. Record oil identity, viscosity, feed condition, throughput and the agreed outlet-quality results. The links above are product listings; missing declarations and validation data must be requested.
