IPA: /ˈpʌlpər/
KK: /ˈpʌlpər/
A machine that crushes or grinds materials, such as roots or coffee berries, into a soft, pulpy substance.
The factory uses a pulper to process the coffee beans before roasting them.
Pulper → It is formed from "pulp" (from Latin *pulpam*, meaning soft or fleshy part) and "-er" (meaning a person who). A pulper is a person or machine that processes or reduces something to pulp, typically in the context of food or paper production.
Think of someone who turns things into a soft, mushy state ('pulp') — that's what a pulper does.
