Definitions

  • the present invention relates to the field of juice extraction from agricultural products and aims to provide a pressing method for controlling a press and an apparatus for performing this method.
  • these known pressing methods comprise several preset pressure levels. At the end of each pressure stage, the pressure is reduced and the materials are mixed. Nevertheless, pressing processes are also known in which several pressure increases can follow one another without intervening mixing. The various parameters of the press cycles of these known methods are determined experimentally by the operator of the press, then programmed and fully reproduced by the automatic press.
  • the object of the present invention is therefore to provide a pressing method in which the levels of the working pressure of the press are determined automatically, i.e. without user intervention, as well as the duration of these pressure levels, the possible connection of several pressure levels Execution of pressure reduction phases and the degree of mixing during the pressure reduction phases, that is to say, the entirety of the parameters which determine the course of a pressing cycle and this depends on the development of the pressing.
  • this process enables a juice of better quality to be obtained as well as better utilization of the pressed material by a type of process which is gentler on the pressed material.
  • a pressing process which enables the control and regulation of a press during a juice extraction process and which comprises at least one sequence of pressure increases for separating solid and liquid substances from agricultural products, such as grapes, berries, fruits and vegetables, by means of a pressing device , which can be driven in a container, characterized in that it is based on measuring the flow rate or the amount of liquid obtained before, during or after the pressing or the partially dried press material remaining in the press 1 after pressing and with a given Compare value, and the value that results from the difference between the values for the flow rate or the amount of liquid obtained and the given values for the flow rate or the amounts, or the amount of the remaining or partially dried pressed material in the press 1 ve to begin, continue, pause, modify, or terminate the juice extraction process, this process being at least partially programmed.
  • Another object of the invention is to provide a device for carrying out the automatic pressing process, characterized in that it essentially consists on the one hand of a programmable apparatus which in particular comprises a device for supplying the press with pressurized liquid and a motor which rotates the press tub and, on the other hand, a pressure transducer, which measures the pressing pressure, and a flow meter, which is arranged below the discharge opening for the liquid obtained, and finally a control panel, which above all enables the determination of the limited duration of a pressing cycle and the value of at least one factor, that decisively influences the cycle.
  • a programmable apparatus which in particular comprises a device for supplying the press with pressurized liquid and a motor which rotates the press tub and, on the other hand, a pressure transducer, which measures the pressing pressure, and a flow meter, which is arranged below the discharge opening for the liquid obtained, and finally a control panel, which above all enables the determination of the limited duration of a pressing cycle and the value of at least one factor, that decis
  • the pressing method is based on measuring and comparing the flow rate or the amount of liquid obtained before, during or after the pressing or the partially dried pressed material remaining in the press 1 after the pressing and with a given value and the value that results the difference between the values for the flow rate or the amount of liquid obtained and the given values for the flow rate or the amount of liquid obtained, or to use the amount of the remaining, if necessary partially dried, pressed material in order to start the juice extraction process , interrupt, change or terminate, this method being at least partially programmed.
  • S n denotes a sequence of any pressure increase in a pressing operation. This sequence S n may be preceded by a preceding sequence S n - 1 and possibly followed by a subsequent sequence S n + 1 .
  • P n denotes any pressure level of a sequence S n of any pressure increase.
  • the pressure stages P n - 1 and P n + i are pressure stages which may be lower or higher than pressure stage P n .
  • P n - 2 and P n + 2 optionally denote the pressure stages which are lower than P n - 1 or higher than P n + 1 .
  • P 1 denotes the first pressure level of a sequence S n of any pressure increase
  • P 2 , P 3 , P 4 , etc. the corresponding subsequent pressure levels.
  • the values of these pressure levels are always in the range between the lowest and the highest value of the pressing pressure which can be achieved and maintained by the press 1, the gradation and the total number of these sections being able to vary depending on the application.
  • At least one batch 4 of pressed material is pressed by means of a plurality of pressure increase sequences S n , which form a pressing cycle C.
  • the pressing or the pressure increase sequences S n are carried out during at least one specific pressure stage P n .
  • the pressing program is changed for the following pressure increase sequence S n or for the later pressure increase sequences S n .
  • the pressing or the pressure increase sequences S n comprise at least one pressure stage P n .
  • the first pressure stage P 1 of a pressure increase sequence S n can be adjusted with respect to its value and / or its duration.
  • the flow or the amount of liquid obtained is measured during a pressure stage P n with a constant pressing pressure.
  • the pressing pressure P is changed during a pressure stage P n on the basis of a flow or a quantity of liquid obtained.
  • the pressing pressure P is controlled as a function of the flow or the amount of liquid obtained during a pressure stage P n .
  • the pressing process is essentially based on continuously measuring at least one size during each pressure increase sequence S n , which size is directly dependent on the amount of liquid currently obtained and is variable during a pressing cycle c, in order to subsequently determine the size measured at specific times and / or to compare their relative fluctuations with the given values and then to continue or interrupt the current sequence S n depending on the result of the previous comparison or comparisons, possibly to repeat the preceding processes until the end of the pressing cycle C and finally, if necessary, emptying press 1 at the end of press cycle C.
  • the pressing method is based more precisely on the continuous measurement and increase in the flow of the outflowing liquid obtained during each pressure increase sequence S n , the subsequent comparison for each pressure level P n , which is achieved by the pressing pressure P, the value D n of the flow D, which is measured at a time t n , and / or the relative increase R n of the flow D, which results from the transition of the pressing pressure P from a lower pressure stage P.
  • the press 1 can be emptied in an automatic emptying cycle or manually by the user.
  • the pressing of a batch 4 of pressed material after loading the press 1 is only started when the flow D of the outflowing liquid of the press 1 is below a predetermined value Do, whereby free juice can flow off in a first phase.
  • the value Do depends on the press material and the size of the press used. For example, Do can preferably be set at 7,000 l / h for grapes and a press 1 with a capacity of 10,000 liters.
  • the determination of the filling quantity T is based essentially also on measuring at the beginning of a press cycle C the duration of the pressure fluid supply which is required to achieve the pressure level P n with the lowest value.
  • the membrane 3 or the movable press member of the press 1 is pressed against the batch 4 of the pressed material, the duration of the supply being proportional to the free volume of the tub 2 of the press 1. If the conditions of the liquid supply as well as the capacity of the tub 2 are known, a calculation of the filling quantity T is possible.
  • the determination of the filling quantity Tr is essentially based on the measurement of the weight fluctuation at the same height of the tub 2, which results from the loading of the tub with pressed material. If the volume of the batch 4 is known, it is consequently possible in principle to determine the filling quantity Tr for a tub 2 with a known capacity.
  • the method according to the invention is also based at the beginning of a pressure increase sequence S n of a pressing cycle C on increasing the pressing pressure P per stage and without delay in succession to a pressure stage P n for which the value D n of the flow D, measured at the time t n, is higher than or equal to a value D 1 which was determined automatically at the beginning of the pressing cycle C, primarily as a function of the measured filling quantity T r - (FIG. 2).
  • the pressing pressure P is therefore not maintained at the pressure stages P n which result in a flow D with a lower value, but after the result of the comparison between the value D n of the flow D at the time t n for each pressure stage P n and the value D 1 immediately increased to pressure levels with higher values.
  • the value D 1 also depends on the type of material to be pressed and the size of the press 1.
  • the value D 1 for grapes and for a press 1 with a capacity of 10,000 liters is preferably 400 I / h, 1,100 I / h and 1,700 I / h for filling quantities Tr equal to 10%, 50% and 100%, respectively linear interpolation enables the determination of all values D 1 depending on Tr.
  • the time t n of the measurement of the value D n of the flow D of the outflowing liquids obtained is calculated from the beginning of the pressure stage P n and can take, for example, 30 seconds from the beginning of the pressure levels P n , which are reached by the pressure P, are set.
  • the value of the first pressure stage P 1 of a pressure increase sequence S n is equal to the value of the first pressure stage P n of a preceding pressure increase sequence S n ⁇ 1 , for which the value D n of the flow D, measured at the time t n , higher or equal to the value D 1 ( Figure 2).
  • the various pressure increase sequences S n are consequently changed depending on the development of the increased pressing during the preceding pressure increase sequences S n - 1 and adapted to new pressing conditions.
  • the pressing pressure P is kept at the pressure stage P n until the flow rate D falls below a value D T which was previously calculated , then the pressure P is increased to a higher pressure level P n + 1 .
  • the relative increase R n of the flow D of the outflowing liquids obtained results from the transition of the pressing pressure P from a low pressure level P n - 1 to a pressure level P n from the following formula: where D M (n) is the largest value of the flow D increased during the pressure stage P n and D m (n-1) is the lowest value of the flow D which occurs when the pressing pressure P changes from the pressure stage P n - 1 the pressure stage P n lies between the values DM (n-1), the largest value of the flow D increased during the pressure stage P n - 1 , and D M (n) and is caused by the pressure P being present for a certain duration the value P n - 1 is held and not increased.
  • the selection criterion for a transition of the pressure P to a higher stage is the value R n , with the exception of the first stage with P n held , for the R n cannot be calculated, and there is no value D m (n-1) (FIG. 1).
  • the pressing method is also based on allowing the pressing pressure P to pass from a pressure stage P n to a higher pressure stage P n + i if the value of the flow D is higher than D 1 as soon as the pressure stage P n measured flow D has fallen below a value D T that was calculated for the pressure stage P n , and this if the relative increase R n of the flow D is greater than or equal to the corresponding predetermined value R.
  • R n is large and, above all, greater than a given value R, this means that the juice flows easily out of the pressed material and an additional increase in pressure is justified.
  • R n is small and, above all, smaller than a given value R, this means that the liquid is blocked in the mass of the pressed material. A renewed pressure increase is therefore useless and the pressure reduction phase with subsequent mixing of the pressed material is therefore appropriate.
  • the value R is preferably in the range of 5% for grapes, for example.
  • the value D T is preferably determined for each pressure stage P n using the following formula: where K is a factor between 0 and 1, which is determined before the start of the pressing cycle C.
  • the value D T therefore determines the duration for maintaining pressure P at a pressure level P n , for which D n is higher than D 1 and R n higher than R if the relative increase R n is measurable.
  • the factor K is determined by the user of the press before the start of a press cycle C, depending on the type of the material to be pressed and the speed of execution of the pressing and the desired drying of the batch 4.
  • a plurality of pressure increase sequences S n are generally carried out, which are interrupted by phases in which the pressure in the press 1 is reduced and the material to be mixed is mixed.
  • these pressure reduction and mixing phases are programmed either when the relative increase R n of the flow for a pressure stage P n is less than the given value R, or when the pressure P is the maximum pressure stage P n that can be reached by the press 1 has reached, and are executed after a delay depending on the change in the flow D during a current pressure stage P n .
  • the method is also based on controlling the pressure reduction of the press as soon as the flow D falls below a fractional value D F of the maximum flow rate D M that is reached during the corresponding pressure increase sequence S n , the fractional value D F depending on the factor K that was set before the start of the press cycle C.
  • G is the fractional ratio of D F / D M.
  • the mixing process of the pressed material after the pressure reduction of the tub 2 of the press 1 is based on rotating the tub 2 for a number of complete rotations T, the number of rotations T depending on the pressure stage P M , which was reached before the pressure reduction, and on the other hand from the measured filling quantity T, and finally from the value K, which was set before the start of the pressing cycle C.
  • the number of rotations T can thus be calculated using the following formula, for example: where Ti, T 2 or T 3 are parts of the number of revolutions T that depend on P M , K and T, respectively.
  • the following tables show examples of the changes in parts T 1 , T 2 and T 3 depending on P M , K and T r , respectively, as above for grapes and for a press 1 with a capacity of 10,000 liters:
  • the automatic pressing process also relies on interrupting a pressing cycle C when the maximum value D M of the flow D reached during a pressure increase sequence S n is less than one is critical value D c , which was determined at the beginning of the cycle C and mainly depends on the filling quantity T r and the capacity of the tub 2 of the press 1, or if the duration of the pressing cycle C exceeds a limit value T L , which is before the start of the Press cycle C was set. In the latter case, it is possible to carry out a further press cycle C with the same batch, the increased values of the last pressure rise sequence S n of the interrupted press cycle C being used, for example, to change the control of the factor K.
  • a further object of the invention is a device for carrying out the automatic pressing method described above, which is shown in FIG. 4 of the accompanying drawings, the device essentially comprising, on the one hand, a programmable apparatus 5, which primarily comprises a device 6 for supplying hydraulic fluid and a motor 7 controls, which sets the tub 2 of the press 1 in rotation, and on the other hand a pressure transmitter 8, which measures the pressing pressure P, and a flow meter 9, which is arranged below the discharge opening 10 for the liquid obtained and finally a control panel 11, which above all the determination of the limited duration T L of a press cycle C and the value of at least one factor K for the cycle C enables.
  • a programmable apparatus 5 which primarily comprises a device 6 for supplying hydraulic fluid and a motor 7 controls, which sets the tub 2 of the press 1 in rotation, and on the other hand a pressure transmitter 8, which measures the pressing pressure P, and a flow meter 9, which is arranged below the discharge opening 10 for the liquid obtained and finally a control panel 11, which above all the determination of the limited
  • the programmable apparatus 5 comprises a read-only memory 12 which contains the control program for the pressing process, as well as the reference tables which enable the values Do, Di, D F , T and D c to be determined depending on the factor K, which was determined before the press cycle C, and the values T r , D M (n), D M and P M measured at the beginning or during the press cycle C.
  • the programmable apparatus 5 also comprises a working memory 13 which, during a pressure increase sequence S n, enables the immediate treatment and storage of the various increased values for the flow D and the pressure P and, if appropriate, until the end of a pressure increase sequence S n Stores values that are necessary to determine the following section or sections in the current pressing cycle C.
  • the latter values can also be written into a magnetic tape storage with autonomous supply, so that the pressing can be resumed after a desired interruption if desired.
  • the device according to the invention can also include a control panel 14 which enables the user to empty the tub 2 of the press 1 and, if appropriate, also to clean it.
