Peptide Skincare, Emulsified to a Standard: A Turnkey Production Line for a High-Growth Eastern Guangdong Brand — vacuum emulsification, stainless storage, and packaging integrated into one GMP-ready cleanroom, built for [200,000] ton

PROMAKE Case Study | Vacuum emulsifying line for peptide skincare · GMP-grade cleanroom · [4,000] L per batch | One-Stop ODM Delivery · A Partnership That Grows

Ask a growing skincare brand what is really holding it back, and you rarely hear "we need one more mixing kettle." You hear something closer to this: the formula works, the orders are coming, and when the line does not perform, nobody wants to own the answer.

Yutai, a Chinese peptide skincare brand, decided not to collect vendors. It handed the whole job to one company. PROMAKE designed and built the line on a one-stop ODM basis: process design, equipment engineering and fabrication, cleanroom coordination, installation and commissioning, operator training, and after-sales service — all inside one scope of responsibility.

This is how that delivery was structured, what it changed for the people running the plant, and why the project turned into a long-term relationship rather than a one-off purchase.

At a glance

• Client:Yutai — peptide-based skincare, China
• Scope:Vacuum emulsifying host, tank farm, hygienic pumps, operating platform, process piping, electrical and control system
• Capacity:[4,000] L per batch
• Build standard:GMP-grade cleanroom, mirror-polished product-contact surfaces, clean-in-place (CIP) ready
• Delivery model:One-stop ODM — one accountable builder from layout to handover, backed on site by local dealers and engineering agents

1. What "one-stop ODM delivery" actually means

The traditional route spreads a new line across four suppliers: the equipment maker, the piping contractor, the cleanroom panel supplier and the packaging vendor. Each one is competent. Each one also has a scope boundary, and the boundary is exactly where problems land. When something goes wrong, the discussion starts and the production schedule pays for it.

Under one-stop ODM delivery, PROMAKE is not a machine vendor bolted onto your project. It is the builder of the whole line:

• Before:line layout and equipment selection built around Yutai's formulation process and capacity target — not around a catalog.
• During:manufacture, transport, positioning and commissioning of the vacuum emulsifying host, the tank farm, hygienic pumps, the operating platform, process piping, and the electrical and control system.
• After:operator training, trial runs with real material, and after-sales maintenance.

One thing is easy to overlook: responsiveness on site usually comes from local people. PROMAKE works with its dealers and engineering agents in the region — they handle site coordination and routine inspections close to the plant. PROMAKE carries the technical responsibility for the line; the local partner carries the speed of response. Together, that is what a complete delivery looks like.

For Yutai, the practical result was a start-up date that could be committed to, acceptance criteria in writing, and exactly one party to call.

The PROMAKE Solution

Vacuum emulsifying heart of the line

At the center sits a PROMAKE vacuum emulsifier with top lifting, a high-shear homogenizer, and a scraper agitator. Under vacuum, the oil and water phases are mixed and de-aerated in one vessel — no open pouring, no trapped bubbles — which is exactly what stable, silky peptide serums require. Temperature, vacuum, and agitator speed are set from an integrated panel, so every batch reproduces the same texture (Fig. 3).

Storage and premix tank farm

A bank of mirror-polished stainless tanks sits on a raised platform for oil-phase and water-phase premixing, heating, and intermediate holding. Sanitary pumps and flexible hoses move phases into the emulsifier automatically, cutting manual handling and cross-contamination risk (Fig. 1–2).

Closed transfer and cleanable design

All product-wetted parts are sanitary stainless with clamp connections, and the high platform gives full access for inspection and CIP-style rinsing. Glossy epoxy flooring and marked walkways keep the room clean and auditable (Fig. 4).

Packaging end

Downstream, stainless workbenches and pass-through windows support filling and inspection, while a shrink tunnel and conveyor close out the line — taking the product from emulsification to finished pack in one connected flow (Fig. 5–6).

2. Installation: checked before arrival, proven before production

How a line is installed decides how it behaves for the rest of its life. PROMAKE manages installation as a project in its own right, not as "deliver and position."

Before anything ships, engineers verify the hall item by item: floor load capacity and protection of the finished epoxy coating, water, drainage and power interface positions, and whether cleanroom pressure differentials and air distribution match the layout drawing. Anything that does not match is corrected before the equipment arrives. The project does not start with an open question.

Installation then follows a fixed sequence: positioning and leveling → operating platform and guardrails → process piping and valve connections → electrical and control wiring → dry-run testing of individual units → full-line trial with real material.

Note that the trial run is not an empty spin. It validates the actual process — emulsifying temperature curve, vacuum level and homogenizing performance — against Yutai's targets. Only when the numbers hold does acceptance begin.

For Yutai, this is what removes the gray zone. There is no "we will see how it runs after it is installed."

3. Training: the whole process, not just the buttons

Whether a line produces good batches consistently depends half on the equipment and half on the people operating it. PROMAKE treats operator training as a required deliverable: hands-on, alongside the line, with a competency check before handover — not a manual left on the bench.

The training covers every step of a production batch:

• Pre-start checks and clearance:equipment condition checks, clean-in-place (CIP) and sanitizing routines, cleanroom gowning and conduct rules.
• Weighing and charging:pretreatment and charging sequence for the oil phase, water phase and peptide actives; when to add functional ingredients, and at what temperature.
• Parameter management:setting vacuum, emulsifying temperature, homogenizing time and speed; filling in batch records and handling deviations.
• Troubleshooting:what to do on the spot when vacuum will not pull, temperature drifts, the homogenizer sounds wrong, or discharge slows down.
• Daily maintenance:seal inspection, homogenizer head care, wear-part replacement intervals, and how to use the check sheet.

None of this costs extra production time. Yutai's operators started working alongside the engineers during the trial phase, so by the time the line was handed over, the team could already run the full sequence from charging to finished product on its own.

4. Quality built into the steel

Peptide actives are gentle and expensive. They dislike air and they dislike heat. Quality control therefore cannot be a final inspection step; it has to be designed into the equipment itself:

• Vacuum emulsifying and deaeration:oil and water phases are mixed, homogenized and deaerated in a single vacuum step, so the product does not entrain air or oxidize, and the cream stays fine and stable.
• Closed transfer:premixing, emulsifying, holding and discharge all move through hygienic piping and pumps. No open buckets, no microbial or foreign-matter risk from manual handling.
• Mirror stainless steel and hygienic connections:every product-contact surface is polished stainless steel with quick-clamp fittings. No cleaning dead spots, and CIP works.
• Centralized, recordable parameters:temperature, vacuum, agitation and homogenizing speed are set in one place and logged batch by batch, so variation between batches is squeezed down to the precision of the machine.
• Cleanroom co-design:equipment layout, air distribution, pressure differentials and the flow of people and materials are planned together. When an auditor walks in, the room explains itself.
• 5. Service that arrives before the breakdown

  For the people running a plant, "peace of mind" comes down to three simple questions: will someone answer when it breaks, can we actually buy spare parts, and can we add capacity without tearing the room apart. On the Yutai project, all three were addressed up front:

  • Designed to be serviced:wall-scraping agitators, homogenizer heads and seals are all built for easy inspection and removal. Quick-clamp connections mean routine cleaning and replacement need no special tools.
  • Service channels:PROMAKE offers both remote guidance and on-site engineer visits, and hands over a wear-parts list with the machine so a stop does not turn into a wait for a shipment. Local dealers and engineering agents can also be on site first and define the solution afterwards.
  • Scheduled follow-up:after start-up, regular visits track equipment condition and process performance, so developing issues are handled before they become failures.
  • Room to grow:the hall layout already reserves space and connections for a second emulsifying host. Adding capacity later means adding a machine, not rebuilding the line.

    6. Yutai's products — and the PROMAKE stage behind each one

    Every product format Yutai sells maps to a specific stage on the line:

    What Yutai sells	Typical products	The PROMAKE stage that handles it
    Serums and essences	Oligopeptide repair serum, hexapeptide firming essence	Vacuum deaeration with low-speed agitation in the emulsifier; closed holding in the tank farm
    Lotions and creams	Peptide revitalizing lotion, repair cream	Oil-phase and water-phase homogenizing in the emulsifier, with wall-scraping agitation holding temperature throughout
    Mask formats	Peptide ampoule media, wash-off masks	Premix and heating in the water-phase dissolving tank; closed transfer by hygienic pump
    Cleansers and body care	Amino-acid cleanser, peptide body care products	Blending in the tank farm at low speed and low foam, pumped to the packaging section
    Packaged goods	Serum bottles, tubes, carton packs	Inspection bench and pass-through window; shrink-wrapper and conveyor for cartoning

    Every stage in that table was designed and built by PROMAKE as one system, planned together with Yutai's cleanroom and building conditions. That is what "one-stop" means in practice: the client never has to translate its requirements between an equipment maker, a construction crew and a piping supplier.
    

    7. Growing together: the client, the local partner, and us

    One-stop delivery is only the starting point. What turns a project into a long-term relationship is that all three parties grow on the same job.

    For Yutai: the plant moved from small manual and semi-manual batches, with batch quality guarded by experienced hands, to a full vacuum emulsifying line running [4,000] L per batch, where consistency is carried by the equipment and its settings. When equipment capability rises, the product range has somewhere to go.

    For the local dealer and engineering agent: the team moved from mostly single-machine sales and ad-hoc installation to taking part in full-line selection, cleanroom coordination and local after-sales. Walking one turnkey project from start to finish changes a team's technical depth, its service radius and its standing in a negotiation.

    For PROMAKE: every delivery adds standardized modules, process parameter templates and training material to the library, which the local partners then carry into the next project. Stronger partners mean faster response for the next client.

    That is the shared growth the project was built around — from doing a bit of everything to doing one thing properly and precisely. Equipment depreciates. A partnership that grows together does not.

    Who	Where they started	What this project changed	What comes next
    Yutai (the client)	Small manual and semi-manual batches, batch quality guarded by experienced hands	A full vacuum emulsifying line running [4,000] L per batch, with consistency carried by equipment and settings	Add another emulsifying host inside the existing hall and push single-batch capacity toward [ ] L
    Local dealer / engineering agent	Mostly single-machine sales and ad-hoc installation	Took part in full-line selection, cleanroom coordination and local after-sales	Larger turnkey projects and spare-parts service
    PROMAKE	Supplied individual machines and equipment packages	Delivers whole-line design, process templates and training systems	Replicate the standard modules into more regions and industries

    The bottom line

    • Quality:air and heat are what ruin peptide actives — vacuum mixing, deaeration and closed transfer keep both out of the process.
    • Efficiency:one accountable builder and one set of acceptance criteria mean a start-up date you can plan a product launch around.
    • Support:training until your team can run the line alone, a wear-parts list in hand, and local partners who can reach the plant quickly.
    • Growth:the layout leaves room for a second emulsifier, so the next capacity step does not mean rebuilding the plant.

    In closing

    Installation with an owner, operators trained until they are confident, quality engineered into the structure, maintenance handled before it becomes urgent, and partners who grow with the project — that is the whole case for the way Yutai bought this line.
