Trial the Screw Oil Press With Your Own Oilseeds
A buyer's guide to planning a screw oil press demonstration using the buyer's actual oilseeds, with practical checks for a request for quotation and acceptance test.
Ask the supplier to run the demonstration on your own oilseed lot, not a generic sample. Seed variety, moisture, cleanliness and oil content can change how a screw oil press behaves, so a trial on your material is the only meaningful comparison between candidate machines.
For the request for quotation, state the seed type, the condition in which you will deliver it, and the batch size you expect to run. Ask whether the demonstration will use a 7.5 kW or 11 kW main motor, and confirm the reference seed processing capacity of 3.5–4 t per 24 h is stated for material comparable to yours. During the trial, compare throughput, cake appearance and ease of adjustment across at least two settings. Agree in advance what sample quantity the supplier needs and who keeps the pressed oil and cake.
For an acceptance test, define measurable outcomes on your material and record the settings used.
Before requesting a quote, confirm with the supplier which oilseeds and condition the demonstration will use, whether your sample can be run, how the 3.5–4 t per 24 h reference capacity was established, and what documentation of the trial you will receive.
