Definitions
- the invention relates to a method for control or Regulation of the pressure in the solid-liquid separation of Press material by means of a during a pressing process a pressure increase at least one press cycle exercising press.
- the material to be pressed is in the form of filled in individual, separate batches and emptied.
- the presses are therefore considered discontinuous designated.
- discontinuous, in Batch operation filter presses known. they are as piston presses, chamber filter presses, tank presses, Packing presses, basket presses, etc. executed, the Press pressure build-up via plates, pistons or membranes hydraulic, pneumatic or mechanical pressure media he follows.
- the invention is therefore based on the object Process for controlling or regulating the pressing pressure of the Specify above type, which of the above Avoids disadvantages.
- this object is achieved achieved that the outflow of the liquid phase from the Press is measured directly or indirectly and that from the time course of the discharge behavior of this phase
- the point in time at which the further pressure rise is determined is limited to a constant value, this being Time for each press cycle in a time interval lies, which begins at the beginning of the drain and after The end of a period of time which is the same double the time between the start of the drain and Entry of the maximum mean flow rate of the liquid phase.
- Fig. 1 shows schematically a horizontal Filter piston press of known type. It comprises one Press jacket 1, which can be released with a pressure plate 2 connected is. The pressure plate 2 is opposite inside the press casing 1, the second pressure plate 3, which via a plunger 6 on a piston rod 13 is attached. The piston rod 13 is in one hydraulic cylinder 12 movably mounted and leads over the plunger 6 from the pressing operations. Between the Printing plates 2 and 3 are lockable Filling opening 14 introduced the material to be pressed 7, through which a plurality of drainage elements 5 extends.
- the drainage elements 5 guide the during the pressing process liquid phase of the pressed material 7 in collecting chambers 8 and 9, which are arranged behind the pressure plates 2 and 3.
- the pressed material can be fruit and the liquid phase around fruit juice.
- the liquid phase comes out of the Press material 7 via the collecting chambers 8, 9 in drain lines 10, 11 outwards.
- the press force is in the generated hydraulic cylinder 12, being between the front pressure plate 2 together with the press jacket 1 and the Cylinder 12 a non-positive Connection exists. After the pressing process is finished Emptying of the press by loosening and axial displacement of the press casing 1 from the pressure plate 2.
- Fig. 2 shows for the known known Process sequence the line course of the pressed Liquid quantities Q1, Q2 and Q3 per stroke of the plunger 6 for three consecutive press cycles.
- everyone shown press cycle begins after the end of previous outflow with that on the time axis t designated piston return stroke R1 to R3 with tearing and Loosen the pressed material 7, followed by one Piston advance V1 to V3 with pressing of the Amounts of liquid Q1 to Q3.
- Piston advance V1 to V3 with pressing of the Amounts of liquid Q1 to Q3.
- For better visibility 2 begins in each press cycle Liquid quantity Q1 to Q3 with the value zero, although for add these quantities Q1 to Q3 throughout the pressing process are.
- Fig. 3 is now known for only one press cycle in addition to the amount of liquid Q squeezed out also the temporal course of the pressing pressure P during a Piston return stroke R and the subsequent piston advance V shown more precisely over the time axis t.
- Time-delayed sets at time t3, the flow Q of the liquid phase.
- this example shows the further increase in Pressing pressure P ends when a pressure threshold P4 is reached and limited to the constant value P4 (solid Curve P).
- the pressing pressure P turned off (see above under "pressing process") and with a Piston return stroke initiated another press cycle (not shown).
- FIG. 5 also shows how the time profile of the pressing pressure P and the amount of liquid Q squeezed out for a single pressing cycle with pressing stroke.
- the times t1, t2, t3, t4 have the same meaning as in FIGS. 3 and 4.
- the time t5 at which the pressure rise in curve P ends and is limited to P3.1 is the same in this process variant by reaching a maximum value of the current drainage capacity dQ / dt ⁇ Qpoint the amount of liquid Q.
- This process aims for an optimal combination of yield and performance with a low wet sweat content. Compared to the procedure according to 4, this results in a faster increase in the pressures P3.1.
- FIG. 6 illustrates the processes in a method according to the invention in which the further pressure rise ends at a time t6 and is limited to a value P3.1 as soon as the mean discharge capacity Q / t ⁇ Lm the amount of liquid Q reaches a maximum value.
- the course of Lm is shown in FIG. 6 by an interrupted curve.
- the time t6 of the maximum value of Lm has been measured since the beginning of the return stroke, i.e. from the zero point.
- the value of Q at time t6 is designated Q3.1, so the maximum value of Lm at time t6 is Q3.1 / t6. Therefore, t6 in FIG. 6 can be determined graphically as the time value of the point of contact of the tangent T from the zero point to the curve Q.
- FIG. 7 shows the processes in an exemplary embodiment of the pressing method, in which the further pressure rise ends at a time t7 and is limited to a value P3.1 as soon as the mean discharge acceleration Q / (t 2nd ) ⁇ Bm the amount of liquid Q reaches a maximum value.
- the designations illustrated in FIG. 7 result in the maximum value from Bm to Q3.1 / (t7) 2 . Therefore, t7 in FIG. 7 can be determined graphically as the time value of the point of contact of the tangent T L from the zero point to the curve Lm of the mean flow rate Q / t.
- the method according to FIG. 7 leads to an optimal pressing result with regard to yield and performance, since above all the average juice acceleration is characteristic of a rapid, gentle drainage of the juice from the capillaries in the fruit material.
- FIG. 8 shows the processes.
- This method has special measurement requirements, since in practice the curves of the quantity of liquid Q (t) often run restlessly and have to be smoothed out to form a differential.
- the formation of the quantities dQ / dt, Q / t or Q / (t 2 ) required for the further method variants is therefore expediently carried out on corresponding signal functions using means of analog or digital signal processing.
- Fig. 9 shows a diagram of a plant for performing a the control method according to the invention or Regulation of the pressing pressure.
- the line 10 outflowing amount of liquid Q is indirectly via the the return chamber of the hydraulic cylinder 12 discharged Hydraulic oil measured using an oil counter 20.
- the on the pressing material 7, the pressing pressure P exerted by the pressing piston 6 is by means of a pressure sensor 21 for the hydraulic oil in the Hydraulic cylinder 12 measured.
- the pressing processes are controlled a hydraulic 22 of a known type by means of therein Valves, pumps and oil pan together with one Pressure control valve 23.
- the output signals from oil meter 20 and pressure sensor 21 are via lines represented by broken lines fed to a process controller 24 together with a pressure controller.
- Process controllers 24 take place in relation to FIGS. 4 to 8 described required signal processing and Time determinations.
- control commands for the control or regulation of the Pressing pressure for the hydraulic cylinder 12 generated and on transmit the hydraulics 22.
- the start of the pressing processes, as well as other automatic The process is an electrical control 25 provided which controls the hydraulics 22.
- the method according to the invention enables Separation behavior of the pressed material adapted, depending on Objective to achieve optimal pressure limits for a press from Press stroke to press stroke. Except for the chosen tax or Control procedure, no setpoint specifications are required. Disruptive setpoints or empirical values can avoided and product data is not required.
- the press is in a process of self-optimization at the pressures and times when the pressure increase is to be limited.

- Ein weiterer Nachteil bekannter anpassender Verfahren liegt darin, dass die angestrebte Optimierung in der Praxis nicht erreicht wird und dass bei Vergleichversuchen mit Verfahren mit vorgegebenen Erfahrungs- Parametern mit solchen Verfahren sogar bessere Ergebnisse erzielt werden.
- Schliesslich lassen sich die Optimierungsziele mit den wirtschaftlichen Zielen nicht vereinbaren.
