Define the product envelope
List viscosity, particles, pH, fat, protein, sugar, heat sensitivity, foaming, abrasive ingredients, and expected cleaning difficulty.
Process Design
How to specify pilot plant equipment without wasting months
A strong pilot plant inquiry defines the product, the process target, the validation data, and the installation constraints. This guide turns vague requirements into an RFQ brief.
Outcome
A clearer scope for equipment configuration, quotation, commissioning, and scale-up validation.
Specification Workflow
Five decisions that shape the final system
Most delays happen when a buyer asks for a machine before defining what the process must prove. Work through these decisions first.
Set the process window
Define flow rate, batch size, temperature targets, holding time, pressure, shear, sampling points, and acceptable product loss.
Choose the validation evidence
Decide which data must be captured: temperature trace, flow, pressure, valve state, cleaning return, alarms, recipe, and batch report.
Confirm installation limits
Review power, steam, chilled water, compressed air, water quality, floor space, drain, ventilation, operator access, and cleaning chemical handling.
Plan scale-up translation
Define how pilot data will inform production heat exchanger choice, hold time, homogenizer pressure, CIP strategy, and sample protocol.
Package the inquiry
Summarize product, trial objective, target capacity, modules needed, utilities, documentation expectations, timeline, and contact details.
Utilities and Interfaces
Premium equipment still depends on practical site details
A pilot line can be beautifully engineered and still perform poorly if utilities, drains, or operating space are not aligned with the process.
Thermal utilities
Steam, electric heating, chilled water, glycol, cooling water, and heat recovery targets affect both thermal performance and installation cost.
Hygienic utilities
Water quality, CIP chemical storage, drain capacity, compressed air, and sterile barriers shape the cleaning and sample handling plan.
Control interfaces
Recipe control, operator permissions, alarms, data exports, batch reports, and remote service access should be scoped before procurement.
Physical layout
Skid footprint, service access, operator side, sample points, tank height, caster or fixed frame, and maintenance clearance matter early.
RFQ Brief
Minimum information for a useful configuration
Copy these categories into your internal request before asking for a quotation. Better inputs produce better equipment decisions.
| Category | Information to provide | Why it matters |
|---|---|---|
| Product | Product family, ingredients, viscosity, particles, heat sensitivity, pH, and target package | Defines product path, pump choice, heat exchanger type, and cleaning risk |
| Process | Thermal target, flow rate, holding time, homogenization pressure, cooling target, and filling method | Shapes module sequence, instrumentation, controls, and utility demand |
| Operation | Batch frequency, operators, cleaning method, data records, sample size, and changeover expectation | Determines automation level, CIP design, documentation, and ergonomics |
| Site | Power, steam, water, air, drains, floor space, door size, and installation restrictions | Prevents late redesign and avoids over-specifying equipment that the site cannot support |
