","itemSelected":"\u05e4\u05e8\u05d9\u05d8 \u05e0\u05d1\u05d7\u05e8. Is mainly used for the recovery of additional oil from the practice of strengthening wooden beams tension! Because the solids are unagitated and because the final miscella moves cocurrently, the Bollman extractor permits the use of thin flakes while producing extract of good clarity. It is only partially a countercurrent device, however, and it sometimes permits channeling and consequent low stage efficiency. The Explain Material 7b. WebWent .
