Write a separate requirement for each spice
A single powder-capacity figure is not a sufficient brief for a mixed spice business. List the whole spices or prepared ingredients, their expected condition, required fineness and daily quantity. State whether the plant makes individual powders, blended seasonings or both.
The spice powder processing plant proposal should identify cleaning, size reduction, sieving, blending and packing duties separately. Ask suppliers to state which preparation is required before material enters the grinder and which equipment is included in their scope.
Measure accepted powder rather than only feed rate
Agree the powder specification and method of checking it before a trial. Record the input mass, accepted powder, oversize material and other losses. If oversize material needs another pass, include that time in the reported output rather than counting it as finished powder.
For illustration, a 50 kg trial that produces 42 kg meeting the agreed specification has an 84% first-pass accepted yield. That example is not a prediction for any spice or machine. Its purpose is to show why two equal feed rates may produce different quantities of usable product.
Assess temperature and product condition
During trials, record feed condition and the powder condition at discharge using agreed measurements. Compare colour, aroma and handling characteristics against your reference sample. Ask how proposed operating settings will be documented so that the demonstration can be repeated during commissioning.
Do not accept a universal throughput promise across different spices without a written test basis. A supplier should explain any change of screen, feed preparation or operating arrangement needed between the products on your list.
Make cleaning and product changeover visible
Walk through access to the grinder, collection points, sieves, blender and transfer equipment. Ask which parts must be removed, who handles them and how the assembly is checked before restarting. Include flavour carryover and your site’s ingredient-control requirements in the cleaning brief.
Ask the site safety specialist to assess dust handling and the proposed collection arrangement. A general product article cannot establish whether a particular site or dust-control design is adequate. The quotation should nevertheless make the equipment boundary and buyer responsibilities clear.
Compare production schedules, not isolated demonstrations
Prepare a sample week showing the order of spices and blends. Include time for cleaning, screen changes, ingredient weighing and packaging. If the business changes products frequently, a fast grinder can still spend much of the shift waiting for changeover or packing.
- Input specification for each spice.
- Powder acceptance and sampling method.
- First-pass output and rework handling.
- Operating observations recorded during trials.
- Cleaning access and change parts.
- Dust collection, blending and packing scope.
Send a reproducible trial brief
Share representative ingredients and a reference powder with AREIUM, together with the proposed weekly schedule. Request separate equipment and utility schedules and an agreed method for recording trial results.
The equipment acceptance trial guide provides a record structure, while the quotation checklist helps separate included equipment from site services. Together they support a purchase based on the actual spice range.
