Selection worksheet
Model selection starts with the real production requirement.
Provide these engineering inputs so shelf area, condenser margin, loading and utility demand can be evaluated together.
Batch target
Container or tray format, loading quantity, units per batch and the required production rhythm.
Cycle basis
Freezing method, drying stages, known cycle duration, endpoint method and condenser demand.
Facility boundary
Room arrangement, door orientation, technical-area access, material flow and maintenance clearances.
Automation level
Loading, recipes, interlocks, alarms, trend records and interfaces with the wider production system.
Project evidence
Required drawings, material records, factory acceptance, training and qualification responsibilities.
Published model data
A scalable SHENSHENG product platform.
Values below are published references. Final performance, utilities and certificate scope must be confirmed in the project quotation.
| System module | Configuration basis | Typical scope |
|---|---|---|
| Material preparation | Product and recipe | Preparation, mixing, filling or tray loading |
| Pre-freezing | Loading method and cycle | Independent quick-freezing room or integrated freezing |
| Freeze-drying chamber | Shelf area and batch target | SSLY or SSFD production platform |
| Vacuum and condensation | Vapour load and cycle | Vacuum pumps, condenser and defrost arrangement |
| Controls and records | Operating and quality requirements | Recipes, interlocks, alarms and trend records |
| Downstream handling | Product and packaging flow | Unloading, transfer, packing and project interfaces |
Integrated lines are project-specific systems rather than fixed catalogue models. The final scope is confirmed in the engineering proposal.
Process-critical controls
What the system must control during the cycle.
These controls connect the equipment specification to actual process risk.
Freezing
Product structure begins hereReview shelf cooling, nucleation assumptions, fill depth and the temperature margin before primary drying.
- Shelf ramp and hold control
- Product probes by agreed scope
- Uniform loading pattern
Primary drying
Balance heat input and vapour flowChamber pressure, shelf temperature, condenser capacity and product temperature must remain within the process window.
- Vacuum-control strategy
- Condenser margin
- Endpoint method
Secondary drying
Reach the moisture targetControlled heating and hold time support desorption without exceeding the product temperature limit.
- Recipe repeatability
- Trend and alarm review
- Stoppering sequence
Utilities & interfaces
The chamber is one part of a production system.
Final requirements are calculated from model, cycle and site conditions. The proposal should clearly allocate every connection and responsibility.

Engineering review
Review the system with application and facility teams together.
A productive technical review includes the product, process, production target, engineering boundary, quality requirements and procurement scope.

Questions buyers ask before selection.
Short answers support early evaluation; project-specific decisions remain subject to engineering confirmation.
Which SSLY model is suitable for a pilot or production project?
Selection depends on container format, units per batch, shelf area, water load, loading method, utilities and documentation scope. A model code should only follow this engineering review.
Can the system include hydraulic stoppering?
The published SSLY range includes common and hydraulic stoppering configurations. The mechanism, pressure and applicable container system must be confirmed in the technical proposal.
What temperature and vacuum values are published?
Selected published SSLY data lists a no-load shelf setting range of −50°C to +70°C and ultimate vacuum of ≤5 Pa. Product performance and cycle conditions remain project-specific.
Can the system integrate with cleanroom loading and plant utilities?
Yes. Door arrangement, technical-area access, material flow, utilities, controls and documentation can be reviewed within the project system boundary.
