PROCESS KNOWLEDGE
Equipment Selection Guide.
Define the material, process target, capacity and installation before selecting a dryer, blender, microwave system, industrial oven or ozone package.
Begin with the process target
Start with what the process must achieve. A machine name alone does not establish capacity, cycle time or product quality. Define whether the duty is drying, blending, coating, milling, curing or ozone treatment before comparing sizes.
- Material: composition, physical form, particle size, bulk density, viscosity, incoming moisture and target moisture.
- Workpiece: usable loading dimensions, mass, arrangement, thermal mass and the coating or resin system.
- Capacity: distinguish kg/batch, continuous feed in kg/h and water evaporation in kg/h. State expected operating hours.
- Acceptance: define the moisture, uniformity, temperature, colour, shape or microbial endpoint, together with the test method.
Compare hot air, vacuum and microwave drying
Compare material temperature limits, drying mechanism and batch handling before comparing model sizes. A brochure temperature range describes an equipment configuration; it is not a recommended setting for every product.
- Hot-air tray ovens: evaluate the CT-C range for batch loads. Check heating utilities, airflow, layer depth, exhaust and cleaning. For continuous handling, compare DW belt dryers and SMH tunnel equipment.
- Static vacuum drying: compare FZG/YZG tray chambers where reduced-pressure drying suits the material. Define volatile components and condensation requirements. For foaming extracts, discuss whether MZG pulse control is appropriate.
- Rotary vacuum drying: SZG combines tumbling with vacuum drying. Assess flow behaviour, fill ratio, sticking and any solvent-recovery duty.
- Microwave vacuum drying: RHWZ configurations cover laboratory, pilot and production work. Material trials should establish power settings, loading, temperature and endpoints; microwave kW alone cannot determine hourly output.
Match the blender to material behaviour and cleaning
Vessel volume and usable loading volume are different. Litres cannot be converted into a loading mass without a defined bulk density. Include the sampling plan and uniformity criterion in the specification.
- For free-flowing powders and granules, compare the vessel motion and handling arrangements of YY, EYH, SYH, FH, VH and SZH.
- For damp material or liquid addition, evaluate agitator designs such as CH and WLDH alongside sticking, shaft sealing and cleaning requirements.
- For components with different densities or addition ratios, discuss whether a DSH twin-screw conical arrangement is suitable.
- Specify vacuum conveying, coating and milling as separate process steps, including conveying distance, screens, collection and dust handling.
Define the engineering inputs for ovens and ozone systems
Industrial heating starts with the load and thermal cycle. Ozone projects start with feed gas, the treatment medium and the dosing objective. Both require a clearly defined system boundary.
- Ovens and curing equipment: usable chamber space, maximum load, ramp and hold profiles, handling, utilities, exhaust and control interfaces.
- Special media: provide the composition, release rate and area-classification requirements. Review complete-machine suitability, ventilation, interlocks and certificate scope.
- Ozone generation: state required output, feed-gas purity and dew point, concentration and cooling conditions, plus the treatment medium, flow and target.
- Include monitoring, off-gas handling, personnel exclusion and post-treatment ventilation in the system specification. Agree how treatment results will be validated.
Prepare a concise enquiry brief
Use the sequence below. Mark unknown fields as “to be tested” or “to be confirmed” and include existing process records, material reports or site drawings where available.
- Project and location; material or workpiece; the intended processing step.
- Required capacity, batch or continuous operation, incoming condition and target condition.
- Temperature limits, vacuum or gas-supply conditions, special media and cleaning requirements.
- Electrical and heating utilities, water, compressed air, installation space and line interfaces.
- Quality criteria, trial arrangements and acceptance methods.
- Requested scope and timing. Price, delivery and service terms are established by the formal proposal and contract.
