Filters are made of stainless steel, ensuring excellent durability and corrosion resistance. In addition, they maintain a high degree of filtering accuracy through continuous long-term use. Features A range of filters between 1 micron and 200 microns is available to suit different applications   MS filters can be used in a wide range of fields from microfiltering of pharmaceuticals, ultrapure water, biochemicals, and so on, to large-volume filtering such as micro-straining of seawater. The slits are finished to a highly degree of uniformity. The slits are extremely fine and uniform. You can select a size of slit that meets your filtering requirements, thus realizing more accurate filtering. Excellent pressure resistance The simple and tough construction of these filters enables them to withstand pressures of more than 1.0Mpa {10 kgf/cm2}. Consequently, you can use them to filter a wide range of fluids from low viscosity to high viscosity. Back flushing completely restores filtering performance. The particles trapped in the filter are removed by applying a reverse jet consisting of a mixture of liquid and compressed air, thus restoring the initial performance of the filter. In back flushing, pressure is applied uniformly to all parts of the slits, leaving no part unflushed. (In the case of a conventional filter, the pores become gradually clogged even if back flushing is carried out, preventing stable operation over a long period. The MS filter completely eliminates this problem.) Heat resistance MS filters withstand temperatures as high as 300. Even highly viscous oils can be smoothly filtered at high temperature. Corrosion resistance The standard material of the MS filter is SUS316L, enabling a wide range of liquids to be filtered. We can also manufacture filters made of titanium or cupronickel. Mechanism of filtering and back flushing   filtering The unfiltered liquid that enters the filter unit from the bottom of the housing is filtered when it passes through the slits from the outside of the filter to the inside. Sometimes, the filter is pre-coated with an filter-aid such as diatomaceous earth. As filtering proceeds, a cake is formed on the surface of the filter, and its diameter becomes large. Recovering the liquid remaining inside the housing At the end of filtering, compressed air is introduced from the top of the housing, and any unfiltered liquid remaining inside the housing is filtered by a horizontal filter plate installed at the bottom and recovered. At this stage, the cake on the MS filter adheres to the MS filter, so this process ends in a short time. Removing the cake, and dehydration The cake adhering to the filter is dropped onto the horizontal filter plate by passing a very small quantity of water and compressed air through the MS filter from the inside to the outside. The cake is then dehydrated by compressed air. Recovering the cake The dehydrated cake is recovered by compressed air after the horizontal filter plate has been released. (The cake contains only a small percentage of water.) Back flushing The water and compressed air introduced into the back flushing tank are flushed in the opposite direction to the filtering direction. As a result, the pipes and the housing are washed and the filter is back-flushed. Normally, this operation is performed two or three times. If necessary, it is possible to sanitize the filter by steam cleaning or washing with disinfectant, for example. Applications Refining liquid foodstuffs such as beer, wine, table vinegar, seasoning, whisky, syrup and juice Refining alcohol and, petrochemical products, and filtering oil and other non-aqueous liquids Filtering and recovering the cake in a chemical process Apparatus Schloker This is a sanitary filter unit fitted with a dehydration mechanism. There is little loss of processing liquid, and a cake containing relatively little water is obtained, thus facilitating post-processing. Permits highly accurate and efficient filtering. Back flushing is complete, enabling preparations for changing over the processing liquid to be performed in a short time. The remaining liquid can be completely recovered. The unit is of sanitary construction, enabling CIP (Cleaning in place) to be performed in a short time. Compact and can be easily moved. The low water content cake can be removed.     Fully automatic filter unit A large volume of liquid can be filtered in a small space. Unmanned operation is possible using automatic sequence control. Any increase in the filtering differential pressure and also the amount of liquid being filtered is detected, enabling the unit to be automatically washed. The unit is completely sealed, preventing liquid leakage or unpleasant odors. Back flushing is completed in a very short time.
