When ester hydrolyzes into acid, is oxidized or polymerized under high temperature, the quality of oil will deteriorate in the procedure frying. Because, if heated, the acidic and peroxide values of the edible frying oil will increase. In recent years, many factories attempt to decrease the acid value through chemical method of filtration, but at last the effect was not very satisfied. Sunshine food and packaging Co., Ltd works as a pioneer to make it into reality that restrain the increase of the acidic values in physical method of filtration.

The hydrolysis of oil into acid is mostly based on a center of particles. If the tiny particles and impurities suspending on the surface of frying oil have been removed, the reaction will have nothing to center on and the speed for hydrolysis will be slowed down greatly. If the catalyst, which attends in the oxidation and hydrolysis of the peroxide and mixes high polymer, has been removed, the deteriorating speed for the quality of oil will reduce greatly, another school considered.

Sunshine LF edible frying oil filter series can get at least -0.06MPA vacuum. The fried oil will be sucked into filtering room by this vacuum, then filters above 5μimpurities through filter sheet and filter compound respectively, till goes to oil tank or returns to oil fryer directly.

The pivotal filtering compound and filter sheet are specially manufactured for all kinds of food fried oil with 120~200℃ filter medium by Sunshine food and packaging Co., Ltd.. The filtering compound has lots of advantages such as possessing strong surface active, dynamic positive charge, and dissociated fatty acid, peroxide colloid, and tiny corpuscule impurities in adhesion frying oil, etc.. At the same time, filter sheet makes the lipin go across freely and separates from the impurities upwards 5μ.

The filtering compound and filter sheet of Sunshine brand are both accredited by Food Sanitation Inspection government. It is our important item to filter the impurity, and develop the Sunshine LF edible frying oil filter successfully undergoes a series of scientific researches.

It has been widely applied in many instant noodle, yam, fried shrimp and fried food factories around 25 provinces and cities all over the country and USA, Australia, Indonesia, Russia and Vietnam and others. It was widely welcome because of its outstanding effectiveness and been praised as a fresh equipment for bringing the low-cost and high quality.
