The effect of construction and technological parameters on the efficiency of apple juice pressing

Abstrakt

The paper presents the results of the research concerning the efficiency of apple juice processing. In the tests apples of variety Idared were used. Two types of laboratory basket presses were applied. The first one was with perforated cylinder and solid bottom and the second one with perforated bottom and solid cylinder. Pressing was carried out in two modes, continuous and periodic. The yield of juice pressing and moisture content in pomace was determined. The yield of extraction was ranged from 52% to 60.7%. There was significant effect of the load mode on the yield of juice pressing. The yield of extraction in periodic mode was higher than in continuous mode for both of investigated presses. The relationship between the yield of extraction and the pressure of pressing was described by the power law equation. There was no influence of press construction on the pressing yield of apple juice.
