The SPTK-1 has a 'pre-infusion' technique that allows coffee particles to be extracted easily. With this function, the espresso is extracted smoothly without any clogging.
What is Pre-infusion?
Pre-infusion refers to the process of pre-wetting beans at moderate pressure for uniform extraction. Not only does it extract well, but it also gives you a richer crema. This pre-infusion technology is another factor that sets SPTK-1 apart from any other.
By preventing the partial flow of extraction, it is possible to extract the natural flavor of the beans at its best. SPTK-1 decomposes soluble flavoring oil to increase the efficiency of flavor extraction.
