• Filtration and thermal drying in one machine
  • High dry matter content in the filter cake can be realized
  • Saving of downstream drying processes / drying systems and thus comparatively low investment costs
  • Shorter cycle times, reduced drainage costs and low specific energy consumption


The hot filter press combines the standard process steps of a membrane filter press, (filtration, filter cake washing and squeezing), with the additional function of a thermal filter cake drying (TCD). As a result, all process steps are carried out in one plant, the hot filter press. Dewatering and drying of the resulting filter cake is thus done without a downstream drying process. Cost-intensive and time-consuming vacuum contact drying is therefore no longer necessary.

Construction and function of the filter press with the thermal-cakedrying - Hot-filter press



In the basic version, the technical design corresponds to a conventional filter press with a plate pack of membrane plates. Filtration, washing and pressing out are carried out as usual. In contrast to the conventional method, the system consists of membrane filter plates and heat exchanger plates, which are installed alternately in a filter press (see illustration). For thermal drying, hot steam and/or oil is applied to the working space behind the membrane and the filter cake is thermally dried accordingly. The advantage of this process is that a high dry matter content (DM content) of over 90% is achieved. On the one hand, the combination of membrane filter plate and heating plate reduces energy and dewatering costs at comparatively low procurement costs. On the other hand, experience has shown that it guarantees low residual moisture in the filter cake. Further information on the description of the high-temperature filter press can be found in the following press article.

schematic process of a hot filter press



The heating plates with heat exchangers consist of a plastic carrier coated with V4A stainless steel on the contact surfaces for heat transfer. The use of this material combination therefore allows for filtration and washing via the heating plate. After the filter press has been completely fed with the process medium, the resulting filter cake is pressed against the heat exchange plate using membrane technology and the heat exchange plates are subjected to saturated steam up to 120°C in a further process step. The steam front forming on the contact surface due to the rapid heat transfer escapes through the filter cake and removes the pore water still contained in the solid.

automatic plate shifter for filter press - working principle

The automatic plate shifter has the task of moving the individual filter plates or the filter plates connected to form a package for discharging the filter press. Experience has shown that this is done manually for smaller filter presses. With larger plate sizes, however, plate shifting is more difficult and requires a plate shifting system. This system makes handling much easier.

swivel plate - bombay doors - working principle

The swivel plate / drip plate for filter presses is used in automatic or manual design primarily to catch the filtrate escaping from the filter plates during filtration and thereby ensure controlled drainage of the dripping water into the filtrate discharge chute. These prevent drops from reaching conveyor belts or cake waste containers. The respective drip plates are mounted below the plate pack. Furthermore, the closed drip plates specifically drain off the cleaning water when cleaning the filter plates and filter cloths in the press. To empty the filter press, the drip plates must be swung open (automatically) / removed (manually) to expose the discharge chute for the filter cake.

filter cake washing - working principle

Filter cake washing, especially in combination with membrane technology, is an optional process step in filter cake post-treatment. This involves chemical/physical treatment of the filter cake or replacement of the filtrate still contained in the filter cake by a washing medium. The dewatering properties of the suspension determine the required filtration or washing pressure. In addition, the maximum permissible pressure depends on the following factors:

  • On the permissible operating pressure of the press frame.
  • From the permissible pressure and temperature stress on the membrane filter elements

core blowing and core rinsing - working principle

In a wide variety of filtration applications, filter cake may not be able to form completely in the turbidity channel (in the inlet area of the filter plates). Whereas in other applications, e.g. fully automatic filter presses, a solid filter cake in the turbidity channel is not desired. If a liquid slurry remains in the turbidity channel after filtration without core blowing, it escapes when the plate pack is opened, which can cause correspondingly serious problems. Soiled filter cloths or deposits on the lower edge of the filter plates are just a few of the undesirable effects. Poor filtration results and high mechanical loads for the fiter press are the consequences.

filter cake blow drying - working pronciple

Residual liquid in the finished filter cake and between the filter cake and filter cloth can never be completely excluded. This results in high and unnecessary disposal and transport costs. The filter cake is dried by compressed air. The compressed air from the pressure plate shoots through the filter cake to the washing plates. The residual water runs off via filtrate drains provided for this purpose. The compressed air forces part of the capillary water out of the filter cake. In this connection, the capillary water adhering between the filter cloth and the filter cake is reduced. This consequently leads to an improvement in the dissolving behavior and the dry substance content (DS content) in the filter cake.

The MSE 2FAST unloading technology significantly reduces the cycle times of the filter press. The unmanned high-speed unloading process results in a faster restart of filtration and thus increases the productivity of the machine.


  • Special design of the hydraulic unit of the filter press, which ensures the following:
  • Automatic electro-hydraulically controlled fast opening/closing of the filter press.
  • Minimization of unproductive dead time during unloading of the filter press -> low delay.
  • The fast opening/closing principle results in shorter cycle times as well as lower operating costs
  • Optimized control philosophy for simultaneous operation of the individual functions
  • Low maintenance requirements

With the versatile applications of a chamber filter press as well as membrane filter press, breakthroughs of the slurry can occur from time to time. To keep contamination of the environment as minimal as possible as a result, there are various options. In addition to a splash guard, a preliminary leakage test is used to check the filter plate package for leaks and preventively minimize damage. How does this work? Contact us!

Extension of the filter press with a spacer

The removable spacer is the ideal solution if you want to secure the possibility of expanding the capacity of your filter press in the future. In doing so, you are spared the need for another new purchase. Each new filter press is optionally and upon request expandable with a spacer for future plate expansions. If a larger capacity intake is required, the cylindrical spacer, which is attached to the hydraulic cylinder and the moving pressure plate, can be removed quickly and easily. The filter press can thus be supplemented by the additional filter plates. However, the maximum capacity expansion depends on the filter press architecture. We will be happy to advise you on this.

Based on the decisive properties of the flexible material, rubber coated filter presses are used primarily for the filtration of particularly aggressive slurrys, such as solvents or acids. In this context, conventional painting of the steel parts is no longer sufficient. In a complex process, the supporting filter press components are accordingly coated with a layer of 3mm thick rubber. In the case of the rubber-coated filter press, the hydraulic column, charging column, pressure plate and support bars are hard rubber-coated for this purpose, and smaller components are made of polypropylene. It is also possible to rubberize only the components that come into contact with the product, such as the charging column and pressure plate. The composition of the rubber coating depends on the special surface requirements of our customers.

Safety engineering filter presses

According to the „Test Laws for Chamber Filter Presses“, a filter press must be secured or made inaccessible not only on the operating side (by means of a safety light grid), but also on the rear side (safety technology for filter presses). Exceptions are non-automated filter presses of simple design, which, for example, do not have a plate transport for automatic filter plate displacement. These filter presses are designed with a 2-hand control, which precludes intervention while the hydraulics are working. In addition, MSE filter presses are equipped with an intervention protection at danger points (above and below the uprights).

For the protection there are 5 different basic variants:

  1. Safety light grid short incl. rear tread protection
  2. Safety light curtain long without rear guard
  3. Monitored sliding door
  4. Monitored automatic rolling door
  5. Monitored safety door

Conveyor belt for filter press

For filter cake transport, driven conveyor systems such as belt conveyors, screw conveyors or trough chain conveyors with hoppers can be used, which are adapted and connected directly under the filter press (erected on a platform). The discharged filter cake is thus transported directly to the corresponding storage. A distance of more than 60 meters in length and 10 meters in height can easily be realized. Depending on the customer’s requirements and the conveying task, it is possible to convey the filter cake horizontally, uphill or vertically. In addition, refinements or special designs, e.g. according to ATEX directives, are possible.
