Setting of the expeller:
- First stop outflow of seeds with a finger before the press cake outlet until a stiff roll of press cake appears - Start with open terminal adjustment bolt. Once the press cake comes out of the two openings the bolt can be tightened. - Turning of the crank at about 50 rounds per minute requires a reasonable force - oil clarifies after app. 24 hours at 50°C and will solidify after cooling.
