A process for producing a seed slurry (SSY) in a seed slurry apparatus (SSA) from solid seed particles (SSP) is disclosed, the seed slurry apparatus (SSA) comprising an input zone (IZ) and a heating zone (HZ), the input zone (IZ) feeding the heating zone (HZ) and the heating zone (HZ) comprising a heating arrangement (HA), said process comprising the steps of feeding the solid seed particles (SSP) from the input zone (IZ) into the heating zone (HZ), the solid seed particles having a seed composition, the seed composition comprising triglycerides, heating said seed composition in said heating zone (HZ) by means of said heating arrangement (HA) to obtain a seed slurry (SSY) at least partly on the basis of partly melted seed composition, wherein said heating involves measuring a seed slurry temperature representation of the seed slurry and said heating is at least partly controlled on the basis of the measured seed slurry temperature representation. Furthermore, a seed slurry apparatus (SSA) and use of a seed sl
