Definitions
- the present invention belongs to the field of apparatus and processes for high pressure processing of substances known as "pumpable”, in particular but not limited to fluids such as beverages, cosmetics, etc.
- High pressure processing is a technology that manages to reduce the microbial load without altering the characteristics of the processed product thanks to the application of pressures higher than 4,000 bar.
- HPP equipment is based on the processing of the product previously arranged in flexible packaging, for example, bottles.
- the classic form of high pressure processing is done in batches, that is, by means of a discrete and non-continuous process. Initially, the products in their final flexible packaging are loaded into containers (made of rigid plastic) that are placed in a steel vessel, which is later filled with water. Once the vessel is filled, it is completely closed and high pressure water begins to be pumped through one or more high pressure intensifiers until reaching 4,000-6,000 bar. This pressure is maintained for a time that can vary between a few seconds and several minutes depending on what is called a recipe.
- a new way of processing high pressure liquids is based on applying pressure to the liquid inside a flexible bag or membrane located inside the treatment vessel.
- the steps of filling and emptying the bag are carried out without opening the machine, that is, without moving wedges or caps.
- An example of this technology is found in application PCT / ES2017 / 070600.
- the product to be treated is introduced and withdrawn through a single product cap.
- This cap has an inlet conduit for the product and another for a cleaning agent.
- the product passes into the bag or flexible membrane, which is located inside the chamber pressure or vessel, through a metal-metal seat valve.
- the air present in the vessel is evacuated through the aeration plug, which has a similar valve, but located in the upper part.
- the operating sequence of a bulk HPP equipment consists of the following stages:
- the filling stage can present problems for the integrity of the bag, since if the amount of liters introduced is not well controlled, it is possible to break the bag due to the pumping pressure itself. Predictably, breaks can also occur in the chamber depressurization stage. During this stage, pressurized water (which can be at 6,000 bar) is instantly released from inside the chamber by opening the discharge valves. For the pressure to equal the atmospheric one, it is necessary that as much water comes out as the one that has been introduced in the pumping stage.
- the bag leak detection system is based on the application of air pressure or any other gas on the outside of the bag once it has been emptied (stage 5) so that in case of breakage from the bag the pressure is detected in the product outlet line.
- the object of the present invention is to provide a device for the detection of ruptures in bags of high pressure processing apparatus that solves the aforementioned drawbacks.
- the invention has a device according to claim 1, provided with means to measure an electrical parameter (resistance, capacitance or current intensity, preferably) between the pressurizing water around the bag and the product inside it. Since the outside of the bag is in contact with the treatment vessel and there is a small amount of water between them, in the case of a connection point between the inside of the bag and the outside, the value of the electrical parameter measured between the pressurizing water and the product will vary if there is breakage. Through the Monitoring this parameter is therefore possible to detect whether or not there is breakage.
- an electrical parameter resistance, capacitance or current intensity, preferably
- FIG 1 shows the stages of HPP processing of pumpable substances in equipment according to the state of the art.
- FIG. 2 shows a diagram of the invention.
- FIG. 3 shows details of the invention.
- Figure 4 shows another variant of the invention in which a connector to the pre-existing bag is used to introduce the electrode into the bag.
- the invention in a high pressure treatment machine provided with a vessel and two caps that close it (5a and 5b), the invention comprises an elongated electrode 1 that partially extends inside the cap 5a in its proximal part and beyond, in its distal part, until it is introduced into the bag of product to be processed.
- the electrode extends through the fill plug 5a but could also be inserted into the vessel through the other plug.
- an electrical cable 13 connects it with a power source, said electrode acting as a cathode.
- the electrode is electrically isolated thanks to an insulator 2 (continuous coating or set of plastic pieces).
- the electrode is isolated both from the plug and from the pressurizing water 10.
- the electrode can have a greasing to ensure mechanical contact with the plug.
- a cap 7 is placed. on the electrode which pushes it causing the male cone shape of the electrode to seal against the female cone shape of the plug.
- the bag 6 where the product to be processed is located preferably but not necessarily, has a connector to the bag 9 through which the electrode enters (Fig. 3).
- the electrode can be introduced through the same pre-existing connector 14 of the bag to the filling cap (Fig. 4) thanks to an auxiliary connector 9 'that is associated with the connector of the bag 14, preferably but not necessarily by means of a coupling. central 15 that facilitates assembly.
- the final section of the electrode, which is inside the bag does not carry insulating material so it is in contact with the product to be processed.
- the connector 9 and cap 7 assembly is optionally provided with a flange 12.
- the flange 12 holds everything together for ensuring the tightness of the assembly during all stages of the process, avoiding communication between the pressurization water 10 and the product to be treated inside the bag, which would lead to contamination of the product.
- the connector 14 of the bag 6 to the product cap 5a has an auxiliary connector 9 ', which is preferably but not necessarily located in the central coupling 15, to introduce the part distal of the electrode, part that is not covered as previously said.
- Both the bag 6 and the connectors 9, 9 ', 14 and the central coupling 15 must be made of an electrically insulating material.
- the power supply to which the cable 13 and the electrode 1 are connected is between 6 and 60V, preferably about 24V of direct current.
- the electrode section must be greater than 1mm 2 . The more electrode section, the more accurate the system.
- the anode is constituted by a second electrode 13 'in electrical contact with the pressurizing water. In the most common case, the high pressure pressurization machine is made of metal, so it is enough to connect an electrode to the external part of the treatment vessel or even to the plug 5a, which are in contact with the pressurization water.
- the equipment has a single product filling and emptying conduit and a single valve whose male and female seats are made of metal. .
- a plastic membrane 3 is arranged in the distal area, the one closest to the bag 6; membrane connected through a stem that is made of an insulating material so that there is no electrical contact.
- the female connector of the bag 14 is made of plastic, so it is already an electrical insulator. Therefore, when the male seat 8 closes, it displaces the membrane 3 in its movement, since it is integral with it, and the bag 6 is electrically isolated from the male valve 8 and therefore from the pressurizing water 10.
- a non-return 5 which can be a plastic ball with spring return or a membrane .
- the non-return valve 5 must always be made of an electrically insulating material. The diaphragm, in combination with the non-return valve, prevents the generation of a current through the filling valve and keeps the electrical circuit open.
- the filling valve must also be isolated by means of the membrane and the non-return valve.
- the electrical parameter can be monitored throughout the pressurization cycle, although the most common will be to monitor it once the pressure cycle has been carried out and the pressurization product has been brought to atmospheric pressure and prior to emptying the bag. To do this, a voltage is applied to electrode 1.
- a voltage is applied to electrode 1.
- an electrical current would pass through the circuit, from the inside of the bag to the outside and through the pressurization water towards the vessel / stoppers until the circuit was closed, producing a current whose intensity can be measured. If the bag maintains its integrity, the electrical circuit remains open since it is made of insulating material, so even if a voltage is applied to the electrode of the cap, as the circuit is not closed, a current will not flow.
- the capacitance or resistance of said circuit can be measured.
- the device of the invention is capable of detecting small failures in the integrity of the treatment bag while it is full, which makes it possible to avoid contamination of the tank and the line of treated product in case of positive detection.
- the procedure is fast and does not penalize the cycle time like that of the state of the art. Also avoid false positives or negatives.
- it is compatible with existing systems, withstands the limitations of high pressure, and is easy to handle and install by the production operator during bag change.
