プレスを提供することを目的とする。The conventional filter press for heating the dehydrated cake during the dehydration treatment is capable of improving the processing capacity and decreasing the water content. The filter cloth is interposed, and if the filter cloth is interposed, the heat transfer efficiency from the heating plate to the cake is poor and it takes time to dry. Further, since the resinous filter cloth is weak against heat and is pressed by the diaphragm filter plate, the folds of the filter cloth are crushed and the performance is deteriorated and deteriorated at an early stage. Further, since both sides of the cake are in contact with the filter cloth, the peelability of the cake is poor.
This invention is an improvement of the above-mentioned conventional drawbacks, in which the heating plate is brought into direct contact with the cake without interposing a filter cloth,
An object of the present invention is to provide a heating type filter press with improved heat efficiency and cake peeling property.
