State of the art

Specialists in the field of hydraulics and hydraulic engineering know

- 1 006420 that turbulent (with chaotic particle trajectories) flow of a fluid in a closed channel is always accompanied by the more intensive conversion of a part of the kinetic energy of the flow of such a medium to heat and its more intensive mixing and homogenization, the higher the actual Reynolds number in comparison with the critical value this number for a particular fluid;

that a turbulent flow can serve as a necessary prerequisite for cavitation;

that cavitation occurs when the continuity of a liquid is violated due to local pressure drops below a critical value that is practically equal to the saturated vapor pressure of this liquid at a specific temperature, and that spontaneous and unregulated turbulence and cavitation occur undesirably and are dangerous.

It is in this aspect that they are described in encyclopedic reference books (see, for example, the articles sauyabop, sauyabop sgoyop, sauyabop poschs and “1bLi1spss” in the vocabulary MsSgo ^ -NS, Ikbopagu £ 8είепыйспб Тсс11шса1 Тсгтз, 8пспспыспыспсспспсспсс, 8спс.

However, turbulence and, especially, cavitation, which purposefully excite and regulate, are practically useful.

In particular, cavitation in fluids is excited by ultrasound, the amplitude of oscillations and the power density of which can be smoothly and precisely controlled (see Polytechnical Dictionary - M .: Soviet Encyclopedia, 1976, article Ultrasonic Processing, p. 520).

However, in the food industry, ultrasonic dispersion of insoluble materials in fluids and heat treatment of the obtained homogeneous products to suppress microflora are traditionally carried out separately (patents 8I 438406 A; IL 25035 C1).

Obviously, with this processing procedure, the cost of acquiring equipment and production facilities and operating costs increase all the more noticeably, the higher the productivity of the production lines and the sterility requirements of the products obtained. Indeed, the output at many enterprises such as dairy or juice plants reaches tens or even hundreds of tons per day. At such a productivity, it is preferable to use devices with flow-recirculating circuits, because only two processes can continuously and simultaneously proceed in them: dispersion of insoluble materials in fluids, including, which is very important, associated hydromechanical destruction of microorganisms, and final thermal suppression of microflora at temperatures that, at least, do not impair the palatability of food emulsions or suspensions.

An example is a device that is known from the description and drawings (especially FIGS. 8 and 9) of Publication AO 98/42987 of international application PCT / IA 97/00003. It has a pump with a rotation drive and a vertical freestanding flow-through reservoir-heat accumulator. In particular, this tank is connected to the supply and outlet pipes, respectively, to the source of cold water and to consumers of hot water;

the bottom part - to the suction pipe of the pump through the recirculation pipe and the upper part - through the means of exciting hydrodynamic cavitation - to the outlet of the pump.

A means of exciting hydrodynamic cavitation is a pressure nozzle of a relatively large diameter with two symmetric bypass nozzles that are substantially smaller in diameter to select a part of the fluid from the pump discharge nozzle and return it to the main stream of the same medium in the form of disturbing jets.

Theoretically, this device can be adapted to the needs of dispersion and heat treatment of dispersions. However, the vertical position of the flow tank and the connection to its upper part of the outlet from the excitation means of hydrodynamic cavitation will complicate the dispersion of any materials in the liquid and the effective separation of the fluid into a fraction, which is fed to recirculation, and a sufficiently homogenized and heat-treated fraction, which is selected for consumption.

Therefore, it is desirable to carry out continuous physico-chemical processes of hydrodynamic processing of fluids so that, if possible, only that fraction of the fluid enriched in the dispersible material enters the recirculation process.

This principle is partially implemented in the device according to the utility model VI No. 9572, which is closest to the proposed device by its technical nature. The known device for hydrodynamic processing of fluids has a pump for continuous supply of fluid to the treatment, which has a suction pipe, in particular, connected to a source of fresh fluid, and a discharge pipe, means for turbulent flow of a hydrodynamically processed fluid, which is located in the flow channel on the outlet of the discharge pipe of the pump and is made, in particular, in the form of a cavitation nozzle, and means for continuous fractionation of the turbulent fluid flow medium per fraction

- 2 006420 enriched with dispersible material and to be recycled, and the fraction of the target product, allocated for consumption.

This tool has the form of a flow reservoir symmetrical about the vertical plane located above the pump with an inclined partition. The outlet opening of the cavitation nozzle is open under the partition. The cavity under the baffle is connected to the suction pipe of the pump by a recirculation pipe, and the cavity above the baffle is connected to the discharge pipe.

In the described device, continuous separation occurs in the Earth’s gravitational field and is based on the fact that relatively cold (and therefore denser) processed fluid accumulates in the bottom part of the tank, and relatively hot (and therefore less dense) processed fluid “floats” into the upper part of the tank.

This separation is sufficient for heat treatment (pasteurization or sterilization) of fat milk, which is accompanied by its homogenization, because coarse particles of fat are contained in a relatively cold part of the fluid flow.

However, in cases when it is dispersion of insoluble materials in the fluid that comes to the fore, and heat treatment of the resulting dispersion becomes a concomitant process, gravitational separation is ineffective. Indeed, if the density of the dispersible material is significantly lower than the density of the dispersion medium, then it will be prematurely removed from the flow-recirculation loop. Otherwise, the bottom of the tank will gradually become clogged with sediment of such material. This undesirable phenomenon is especially noticeable in the production of a product such as soy milk, and similar suspensions.

SUMMARY OF THE INVENTION

The basis of the invention is the task, by improving the means of continuous fractionation and its interrelations with the turbulization means and the pump, to create a device in which, when hydrodynamic processing of fluids, firstly, premature ablation of dispersible materials from the flow-recirculation loop or their deposition would be practically eliminated inside such a circuit, and secondly, the resistance of the resulting emulsions or suspensions to delamination and spoilage during long-term storage would increase substantially.

The problem is solved in that in a device for hydrodynamic processing of fluids, including a pump for continuously supplying fluid to the processing, which has a suction and discharge nozzles and is connected to a source of fresh fluid, means for turbulizing the flow of the processed fluid, which is located in the flow channel at the outlet of the discharge pipe of the pump, means for continuously fractionating the flow of turbulized fluid into a fraction enriched in a dispersible material and to be recycling, and the fraction of the target product, consumed for consumption, which is made in the form of a flow tank, is connected to the outlet of the turbulization means, connected by a recirculation nozzle to the suction nozzle of the pump and equipped with a discharge nozzle, according to the invention, the means of continuous fractionation of the turbulent fluid flow is made round in the cross section of the tank, the output of the turbulization means is tangentially connected to this tank near one of its ends, and the recirculation the outlet and outlet pipes are equipped with shut-off and regulating elements and are connected to this reservoir from the side opposite to the connection of the flow turbulization means respectively in the collection zone of the fraction enriched with dispersible material and in the collection zone of the target product fraction.

The spiral twisting, which is achieved by tangential supply of a turbulized fluid flow into a round tank, significantly enhances the efficiency of its separation into fractions. Indeed, in the emerging field of centrifugal forces, large particles of dispersible materials, whose density is less than the density of the dispersion medium, will tend to the geometric axis of the round tank, and large particles of dispersible materials, whose density is higher than the density of the dispersive medium, will be discarded to the side wall of the round tank.

Accordingly, in the homogenization and heat treatment of food products such as fat milk, a fraction that is enriched in coarse particles of fat (and in which a substantial portion of the microflora to be destroyed is usually concentrated) is selected for recycling near the geometric axis of the round tank, and in the manufacture, for example, of soy milk, in which the density of the solid material is higher than the density of water, a fraction with a high content of coarse particles, which are usually seeded with microorganisms, is recirculated tion round near the side wall of the tank.

Thus, premature entrainment or precipitation of dispersible materials is eliminated, microflora suppression is significantly accelerated, and a substantial increase in the resistance of the resulting emulsions or suspensions to delamination and damage during long-term storage is ensured.

A first additional difference is that said round tank is horizontal and has a central recirculation pipe and a tangential discharge pipe.

The second additional difference is that the specified round tank is located vertically and has a central recirculation pipe and a tangential outlet pipe.

These two particular embodiments of the invention are most effective for the hydrodynamic treatment of fluids such as fatty dairy products with the aim of homogenizing and pasteurizing them.

A third additional difference is that said round tank is horizontal and has a tangential recirculation pipe and a central discharge pipe.

A fourth additional difference is that said round tank is horizontal and has a radial recirculation pipe and a central discharge pipe.

A fifth additional difference is that said round tank is vertically arranged and has a tangential recirculation pipe and a central discharge pipe.

These three particular embodiments of the invention are most effective for the hydrodynamic treatment of fluids such as juices with pulp with the aim of homogenizing and sterilizing them and are acceptable in the production of soy milk.

The sixth additional difference is that

a) the specified round tank is equipped with a round cross-sectional chamber for temperature control of the treated fluid, which has central inlet and outlet openings, is located inside the round tank, communicates with the cavity of this tank through the central inlet and is adjacent to that end wall of this tank, near which is connected means for turbulizing the flow, and a thermostatic fluid degasser, which communicates with the thermostatic chamber through its outlet,

b) the outlet pipe of the target product is connected to the bottom of the specified degasser, and the upper part of this degasser communicates with the atmosphere.

Devices of this type are particularly effective in the hydrodynamic treatment of fluids such as fatty dairy products with the aim of deodorizing them and, in particular, removing so-called "feed" odors or to thicken the target product.

The seventh and eighth additional differences are, respectively, that the said round tank, thermostatic chamber and the degasser are located either horizontally or vertically.

Naturally, in both particular embodiments of the invention, the recirculation pipe, depending on the density of the dispersible material, can be connected to a round tank both near its geometric axis and near its side wall.

The ninth additional difference is that the specified round tank is located vertically, connected in the bottom to a recirculation pipe and has a built-in cyclone for thermostating and degassing of the treated medium, which is equipped with a perforated partition in the upper part, while the cavity of this cyclone is connected above the perforated partition - to the atmosphere, under the perforated partition - to the discharge pipe of the pump through its own tangentially oriented means of turbulization, and to the bottom oh part - to the outlet pipe.

Such a device is most suitable for the production of products such as soy milk or the recovery of ordinary milk from a powdered concentrate for the purpose of homogenization and heat treatment and, in addition, can be used to thicken these foods or to thicken juices.

It is clear that when choosing specific forms of devices for hydrodynamic processing of fluids, arbitrary combinations of these additional differences with the main inventive concept are possible and that the preferred examples of its embodiment described below in no way limit the scope of the invention.

Information confirming the possibility of carrying out the invention

A device for hydrodynamic processing of fluids can be manufactured in a wide range of design options, which differ in the number of functional units and parts and / or their relative position in space. However, regardless of the design, all devices according to the invention (see Fig. 1 -1 6) have a pump 1 in series in the hydraulic circuit for continuously supplying fluid to a hydrodynamic treatment, having not specifically designated suction and discharge nozzles and, usually indirectly, as further indicated, associated with the source of fresh fluid, at least one means 2 for turbulizing the flow of the processed fluid, which is located at the outlet of the discharge pipe of the pump 1, and means for continuously fractionating the turbulized fluid stream into a fraction enriched in a dispersible material and to be recycled, and a target product fraction allocated for consumption.

This last tool has the form of a circular flow tank 3, round in cross section, to which the outlet of turbulization means 2 is tangentially connected near one of its ends. The tank 3 can be located both horizontally (see Fig. 1, 5, 7 and 11), and vertically (see Fig. 3, 9, 13 and 15). The vertical position is preferable with limited available production space.

From the side opposite to the connection point of means 2, the tank 3 has in the collection zone of the fraction enriched in dispersible material a recirculation pipe 4, which is connected to the suction pipe of the pump 1 or directly serves as such pipe, and in the collection zone of the fraction of the target product there is a discharge pipe 5 to supply the resulting dispersions for bottling and capping or directly for consumption.

It should be noted that regardless of the equipment of the device according to the invention with additional means of influencing the selected fraction of the fluid, the collection zone of the fraction enriched in the dispersible material is usually located either near the geometric axis of the reservoir 3 if the density of the dispersible material is less than the density of the dispersion medium (therefore, in Fig. 1 and 2, 3 and 4 it is shown that the recirculation pipe 4 is introduced into the Central part of the cavity of the tank, and the discharge pipe 5 is connected to the wall of the tank 3); or near the side wall of the tank 3, if the density of the dispersible material is higher than the density of the dispersion medium (therefore, in Figs. 5, 6, 7, 8, 9, and 10 it is shown that the recirculation pipe 4 is connected to the wall and the outlet pipe 5 is inserted into the central part of the cavity reservoir 3).

Similarly, in FIG. 11-16, the recirculation pipe 4 is shown by solid lines for cases of selection of fluid for recirculation from the peripheral part of the cavity of the tank 3, and dashed lines as a continuation of the solid lines for cases of selection of fluid for recirculation from the central part of the cavity of the tank 3.

The supply pipe 6 for supplying fresh fluid to the hydrodynamic treatment can be connected either to the turbulization means 2, which in this case acts as an ejector, as shown in the drawings, or to the same turbulization means 2 for supplying at least one disturbing jet into the main flow of the recirculating fluid (in this case, the nozzle 6 can be equipped with a means of dividing the supply jet into at least two disturbing jets, the entry openings of which can be made either sequentially by flow, either concentrically, as described in the aforementioned international publication \ UO 98/42987), or to the recirculation pipe 4 (preferably before entering the pump 1 through such a shut-off-control element as a three-way valve or valve).

A hydraulic circuit, not particularly shown, is also possible in which the supply pipe 6 is connected to the turbulization means 2 and to the recirculation pipe 4 through a three-way shut-off element that is capable of shutting off the supply of fresh fluid in one of the

- 5 006420 directions, and smoothly regulate its flow in both directions.

All of these pipes 4, 5 and 6 are equipped with locking and regulating elements 7. Their design can be either the same or different. These elements 7 specialists can choose from among the cranes and / or valves available on the market. Naturally, using these elements 7 according to the rules that are known to specialists, to equip any of the devices according to the invention, a system for automatically controlling the hydrodynamic treatment of selected fluids can be constructed and used, which includes well-known means of measuring the temperature of a fluid at least at the inlet a circular tank 3 and inside it in the selection zone of the treated fluid.

Additional means of influencing the fraction of the fluid sampled at the output can serve as

a) thermostatic chamber 8 of the treated fluid and the degasser 9 of thermostatic fluid in communication with it (see FIGS. 11 and 12, 13 and 14), or

b) cyclone 10 for thermostating and degassing of the treated fluid (see Fig. 15 and 16).

In cases (a), a round tank 3 and a temperature control chamber 8, which has central inlet and outlet openings in the end walls and, if desired, perforations in the side walls are not shown in the drawings, can be arranged horizontally (Figs. 11 and 12) and vertically (Figs. 13 and 14). However, it is advisable that the recirculation pipes 4 are connected to the wall or to the central zone of the cavity of the tank 3 far from the central inlets of the temperature control chambers 8, the temperature control chambers 8 have horizontal perforated partitions 11 in the upper parts, the space above such partitions 11 is connected to the atmosphere through the pipes 1 2 with locking and regulating elements 7, and outlet pipes 5 with locking and regulating elements 7 were connected to the bottom parts of the chambers 8.

In cases (b), a round tank 3 and a cyclone 10 for thermostating and degassing of the treated fluid are usually arranged vertically. The cyclone 10 is provided in the upper part of the horizontal perforated partition 11. The cavity of this cyclone 10 is connected above the partition 11 through the pipe 12 with a locking-regulating element 7 to the atmosphere; under the partition 11 through its own branch pipe-coupler 13 with a locking-regulating element 7 and a tangentially oriented means of turbulence 14 - to the discharge pipe of the pump 1, and in the bottom to the outlet pipe 5.

Means 2 turbulization flow can be selected from the group consisting of

a) mechanical means, including either in the form of so-called "poorly streamlined bodies" that are rigidly fixed inside the channels for pumping fluids (see, for example, patents IL 8051 A and 17850 A, KI 2131094 C1, etc.), or in the form of generators of ultrasonic vibrations, whose sound ducts should be acoustically connected to the walls of the channels for pumping fluids (see, for example, patents 8I 1628994 A1 and IA 25035);

b) hydraulic (jet) means, for example, in the form of at least one hole in the channel wall for pumping the main fluid flow, which is open directly into the cavity of this channel and serves to supply a disturbing jet of the same or different chemical composition of the fluid at an angle to the direction of the main stream, preferably selected in the range from -60 to +45, (see, for example, Figs. 1-3, 5 and 6 and lines 06-38 on page 10, page 11 in full, p. 12 to line 37 inclusive and lines 02-16 on page 14 in publication AO 98/42987 of the same inventor ), And

c) combined means, for example, either in the form of a poorly streamlined body having a central hole, which is mounted on a hollow bracket in an axisymmetric channel to pump the main fluid flow, and an external fluid source to form a perturbing stream, which is fed through the hollow bracket and released towards the main stream through the specified central hole (see, for example, the book: Sedov LI Mechanics of a continuous medium, vol. 2, Moscow, 1976, p. 82), or in the form of a combination obvious to specialists at least one hole in the channel wall for supplying a perturbing jet and a sound duct brought into contact with this wall from the ultrasonic vibrations generator, or in the form of a combination of at least one poorly streamlined body installed inside the channel and the sound duct from the ultrasonic vibrations generator introduced into contact with the wall of this channel.

In specific devices for hydrodynamic processing of fluids, it is advisable to use preferably centrifugal (although other rotary) mechanical pumps 1 are also acceptable; preferably inkjet (usually from the number described in publication AO 98/42987) and / or made in the form of poorly streamlined bodies means 2 and 1 4 turbulization.

And finally, the nozzles 12 (see Fig. 11-16) can be, if desired, connected to the atmosphere through means of intensification of a suction type not well shown in the drawings, such as well-known to those skilled in the art and available on the market exhaust fans, water-jet and similar vacuum pumps in terms of performance .

The devices described above are used for hydrodynamic processing of fluids as follows.

- 6 006420

When starting the described device, regardless of the specific form of embodiment of the invention, first the shut-off-regulating element 7 on the outlet pipe 5 is closed (and for the devices according to FIGS. 11-16 and on the nozzle 12 for communication with the atmosphere), the pump 1 is turned on, the shut-off element 7 is opened on the supply pipe 6 and fill all the cavities of the device selected for processing fluid. Then, the shut-off-control element 7 on the supply pipe 6 is temporarily closed and in the recirculation mode through the pump 1, the turbulization means 2 and the round tank 3 bring the fluid to the required homogeneity and temperature in the zone of its selection for withdrawal from the device.

Then, almost simultaneously, the locking and regulating elements 7 are opened on the supply 6 and outlet 5 nozzles so that the supply of fresh fluid to the device and its flow rate for selection are balanced, and at least periodically controlling the homogeneity and temperature of the selected hydrodynamically treated fluid, the device is brought into stationary mode (naturally, in the devices according to Figs. 11-1 6, the locking-regulating element 7 on the pipe 1 2 is also opened for communication with the atmosphere).

A feature of the operation of the device in any of the possible particular embodiments of the invention is that the fluid flow tangentially leaving turbulence means 2 inside the circular tank 3 and interacting with its walls, is not only heated due to the conversion of part of the kinetic energy of the stream to heat, but also twists into a spiral (which is indicated either by a wavy line with an arrow on the odd, or an arcuate line with an arrow on the even figures).

With this movement of the hydrodynamically processed fluid inside the circular tank 3, not only the temperature field is leveled, but also a field of centrifugal forces arises. In it, when the supply of fresh and the selection of the treated fluid is equal in the autoregulation mode, there is a continuous fractionation of the flow in which a part of the processed fluid is enriched with dispersible material and continuously fed to recirculation through the pipe 4 to the pump 1 and then through the turbulization means 2 again to the round tank 3.

Indeed, as mentioned above, large particles of dispersible materials, whose density is less than the density of the dispersion medium, will tend to the geometric axis of the round tank 3, and large particles of dispersible materials, whose density is higher than the density of the dispersive medium, will be discarded to the side wall of the round tank 3. Moreover, almost every particle of the dispersible material remains in the flow-recirculation circuit until its size and mass become so small that it composes a homogenized and heat-treated (pasteurized or sterilized) fluid will be discharged into the outlet pipe 5.

The fractionation of hydrodynamically processed fluids described above takes place in the devices of FIG. 1-10 in the full volume of the round tanks 3, and for the devices according to FIG. 11-16 in that part of the volume of these tanks 3, which do not include means of thermostating and degassing.

It is understood that during hydrodynamic processing in the devices according to FIG. 1 -1 0 all impurities that are contained in dispersible materials and / or dispersion media remain in the target products.

The devices according to FIG. 11-16 allow you to stabilize the temperature selected through the outlet pipe 5 of the target products, significantly deodorize them and, if necessary, thicken to a pasty state.

Thus, the hydrodynamic treatment of fluids in the devices according to FIG. 11-14 provides for the passage of the fluid through the thermostatic chamber 8 and the degasser 9. Naturally, the part of the fluid entering the thermostat chambers 8 calms down and is kept in the zone of maximum temperatures for some time, because it is precisely on the periphery of such a chamber that part of the kinetic energy of the stream is converted fluid flowing out from the turbulization means 2, heat is released.

Then, the calmed and heated fluid enters the degasser 9, where under the influence of the atmosphere, volatile substances and vapors of the dispersion medium, which freely pass through the holes in the perforated partition 11, are intensively released through the nozzle 12, in particular, it is possible to effectively deodorize the milk products and soy milk.

In the devices of FIG. 15-16 thermostatic processes of the selected fluid at high temperatures and its purification from volatile impurities occur more intensively in one apparatus, namely in cyclone 1 0 integrated into the round tank 3. In this cyclone 1 0 part of the fluid is continuously taken in front of the main tool 2 turbulization, served through a branch pipe 1 3 and additional means 1 4 turbulization, which is usually set to cavitation mode.

The cavitating part of the fluid at the outlet under the baffle 11 in the upper wide part of the cyclone 1 0 is throttled, which contributes to the breakdown of cavitation and the intensive release of volatile impurities from the liquid dispersion medium and the evaporation of this medium.

Thus it is possible to achieve intense thickening of the target product, which is selected from

- 7 006420 the lower part of the cyclone 10 in the outlet pipe 5.

It is clear that the above examples of the constructive implementation of the inventive concept and examples of technological capabilities do not exhaust all the specific structures and all possible aspects of the industrial application of the device according to the invention and in no way limit the scope of rights of the inventor.

An invention in any form of implementing an inventive concept is implemented industrially using conventional means in mechanical engineering.

Accurate control of the concentration of dispersible insoluble materials in the part of the fluid continuously selected for recirculation allows one to practically eliminate the premature ablation of such materials from the flow-recirculation circuit or to settle in such a circuit and to ensure storage-stable emulsions and / or suspensions (including deodorized and substantially condensed).
