Recess Filter Press

TRIMURTI FILTER PRESSES are well known for their up-to-date design, sturdy construction, and easy operation. These are largely used by chemical and Sugar factories and especially by OIL MILLING INDUSTRY for producing a first-class filtered oil and also saves an enormous loss of time and space required for the oil to settle down in tanks.

These are prepared in two types :
(1) Recessed Types
(2) Flush Plate and Distance Frame Type.

RECESSED TYPE

The plates in this type are recessed so that when two plates are closed together, a chamber is formed. Each plate has a center feed hole and the faces are cast with pyramid type indentations to increase the filtering area. Filter cloth is placed on each plate and fastened back to the plate with hollow clips. When the press is closed, the cloth forms a tight joint between the machined edges of the plates. The liquid to be filtered is pumped into the press to fill up the chamber formed by the plates. The liquid is then forced out through the cloth, to the passage at the base of the plate, and hence to a trough through bib cocks.

FLUSH PLATE AND DISTANCE FRAME TYPE

In this type, the machined edges are almost at level with the indentation surface. A separate form is used between them to form the chamber. The cloths are not fastened in any way to the plate, but only hang over the frame and nipped between the edges of the plates and distance frames, when these are closed together. The filter cloth is thus easily renewed for cleaning. The thickness of the frame determines the depth of the chambers. The type is recommended for filtering oils with the use of filter aids, such as fullers earth, Kieselguhr, or activated carbon.

STANDARD EQUIPMENT

These are supplied with suitable belt-driven on motorized pumps. Standard equipment also includes the necessary safety valve air vessel, pressure gauge, out, et cocks trough, etc. Filter cloth bags are supplied at extra cost.
