Lemon Juice Membrane Filtration Technology for Clarification
Traditional lemon juice clarification using diatomaceous earth and plate-frame filters often loses natural flavor and consumes large amounts of filter aids. Cross-flow membrane filtration achieves low-temperature clarification of lemon juice, intercepting pulp, pectin and macromolecular impurities while preserving vitamins and aroma substances. Two mainstream membrane types, hollow fiber membrane and ceramic membrane, are available. The skid-mounted system supports automatic CIP cleaning, delivering stable clear filtrate with longer shelf life. Lab trials can be conducted to confirm performance before industrial deployment.
Basket Centrifuge vs Rotor-Type Laboratory Centrifuge for Liquid-Solid Separation
This article compares experimental basket centrifuges and conventional rotor-type laboratory centrifuges in principle, separation performance and application scenarios. The basket centrifuge adopts filter separation, which can directly trap solids inside the perforated basket and obtain filter cake with low moisture. In contrast, rotor laboratory centrifuges only realize solid sedimentation in centrifuge tubes, and the sediment still retains high water content. Experimental basket centrifuges are more suitable for lab trials of plant extraction, protein and beverage clarification requiring solid recovery, while rotor centrifuges fit small-volume simple sediment tests. The comparison helps researchers and purchasers select the right lab solid-liquid separation equipment according to their target products.
Wine Clarification: Ceramic Membrane VS Diatomaceous Earth Filtration
Wine clarification is vital to guarantee wine clarity and shelf life. Diatomaceous earth (DE) filtration has long been the mainstream clarification method for wineries, yet it suffers from disposable consumables, solid waste, unstable filtration and loss of wine aroma. Ceramic cross-flow membrane filtration serves as an advanced alternative. This article compares the two technologies and introduces the advantages of ceramic membrane, including stable clarification, reusable membrane elements, less flavor loss and automatic operation. It helps wineries select proper wine clarification equipment.
