Definitions

  • the invention relates to dietary fibers and more particularly to novel dietary fiber products and the process and apparatus for producing same.
  • Dietary fibers are used in a variety of food applications as both a means to reduce overall fat and calorie content for the ultimate food product and as a bulking agent replacement for products with reduced sugar or sweeteners.
  • dietary fibers are employed as a fat mimic, approximating the mouth feel and texture of fat while affording a lower calorie alternative.
  • dietary fibers are employed in efforts to reduce sugar and other sweeteners especially from baked goods such as snack food, cakes, pies and bread products. In such products when the sugar content is reduced a bulking agent is used to return the desired mass, texture and mouth feel to the product.
  • Dietary fibers are generally fibers derived from corn, wheat, cellulose, oats, or other natural grains. Generally a dietary fiber is high in insoluble (i.e. indigestible) fiber content, ideally low in calories and low in fat content. Most dietary fibers offer great promise as an improved dietary additive to food products, but there are also several drawbacks.
  • Dietary fibers tend to absorb many times their weight in moisture, requiring longer bake times for baked goods incorporating such fiber ingredients.
  • Newer dietary fibers derived from corn also provide very high calories, much the same as found in various starches.
  • Such abrupt pressure increases, or pressure shock waves are believed to transmit energy in three basic forms: high compression forces; heat via friction; cavitation.
  • Studies of cavitation show that the heat produced during a cavitation effect can be very high, if only for a short period of time.
  • pressure shock waves applied to a dispersion e.g. slurry containing dietary fibers can produce a modified form of dietary fibers through the effects of the heat energy caused by cavitation and the compressive forces produced by the pressure shock wave application.
  • Figure 1 is a diagrammatic illustration of the process for modifying dietary fibers in accordance with the invention
  • Figure 2 is an overall illustration of apparatus for carrying out the process of dietary fiber modification through pulse pressure treatment
  • FIG. 3 is a more detailed illustration of the piston component of the pressure treatment apparatus of Figure 2;
  • Figure 4 is a diagram of the baffled chamber component of the pressure treatment apparatus; and Figure 5 is a diagram of a baffle ring used in the baffled chamber component of the pressure treatment apparatus.
  • a treatment vessel 101 contains a fluid carrier material 103, e.g. water, to which are added raw dietary fibers 102. Agitation provided by a mixer 104 turns this mixture into a slurry in which the dietary fibers are dispersed throughout. Once properly mixed, the slurry dispersion is delivered to the pressure treatment device 106, whereupon a single pressure treatment may be applied to the fiber slurry. However, in some instances it may be preferable to provide multiple cycles of pressure treatment through a repetition of the treatment process. Such repetition is indicated by arrow 107.
  • a fluid carrier material 103 e.g. water
  • the pressure treatment consists of the application of a single, or continuously recurring pressure shock waves to the slurry 105.
  • the pressure treatment is measured in applied or compressive pressure as a function of the time period the pressure is applied to the slurry 105.
  • the pressure levels can be as low as 1 psi to as high as 90,000 psi from the equipment provided for test purposes. Time durations range from 0.001 to 1 full second, with most treatment time periods being in the range of 0.1 to 0.25 seconds.
  • Pressure is applied in the preferred embodiment via a piston pressure applicator as shown in Figures 2 and 3. However other designs are possible for the application of the pressure treatment, such as ones using multiple pistons for pressure application.
  • the pressure treated fiber slurry 108 exits the pressure treatment device 106 by being pumped and may be subjected to additional pressure treatments as illustrated in the re-cycle loop 107, or it may be directed to a filtration device 109 which acts to remove the solid, pressure treated particulates from the slurry, generally producing a wet cake 1 10 which is then delivered to the appropriate drying mechanism 1 1 1 to produce the dry powder, pressure treated dietary fiber product 1 12.
  • the drying device 1 1 1 may be an oven, spray drier, vacuum dryer, fluid bed dryer, flash dryer or any other mechanism which will remove the residual moisture 103 from the pressure treated fiber, resulting in a dry powder form 1 12.
  • FIG. 2 A preferred embodiment of apparatus suitable for modifying dietary fibers in accordance with the invention is shown in Figures 2, 3, 4 and 5.
  • the present starting material is conventional (commercially available) dietary fiber, the process is shock treatment, and the result is modified dietary fiber, exhibiting properties not previously obtainable.
  • the apparatus includes an air operated converted hydraulic pump 2 with a piston acting as the means for exerting a pressure pulse on the material which is pumped through the apparatus.
  • a reservoir 5 is placed at the input of the apparatus.
  • the reservoir 5 is usually not heated but may be in some cases by heating coils, not shown.
  • the reservoir 5 may also be stirred to allow the dietary fibers to be dispersed prior to passing through the apparatus.
  • the dietary fibers can be provided to the reservoir 5 in either of the following states: a) A heated mixture b) A mixture at ambient conditions c) A mixture or slurry containing dispersed particulates which are undissolved in a liquid carrier
  • a transfer conduit 6 leads to pressure applicator assembly 2.
  • Transfer conduit 6 may be heated with heating coils to maintain the temperature of the pre-mix 40 as it passes to and from the pressure applicator assembly 2.
  • valves 3 and 4 At opposite ends of the pressure applicator assembly 2 are placed valves 3 and 4, which may be solenoid valves, manually operated valves or an automatic check valve system.
  • Pressure assembly 2 consists of valves 3 and 4 on opposite ends of compression chamber 1 , connected to the fluid flow conduit channel 6.
  • pressure applying device 2 Connected to compression chamber 1 is pressure applying device 2 which has a movable piston 20 within housing 42, as seen in Figure 3.
  • Movable piston 20 is displaced within housing 42 by motor 22.
  • the motor 22 may be hydraulic, air powered or electrically or combustion powered.
  • the output transfer conduit 7 is connected to the exit valve 4 and leads to a separate baffled chamber 23. Pressure treated materials exit the compression chamber 1 , travel through the output valve 4 and encounter transfer conduit 7, which is of significantly smaller inner diameter that the input transfer conduit 6. This smaller inner diameter acts to develop a back pressure within the fluid flow which helps output valve 4 to stay closed longer, thereby helping to maintain the elevated pressure created within the compression chamber 1 to last for a longer period of time.
  • Transfer conduit 7 may be heated by a heating coil (not shown) to maintain the temperature of the treated mix.
  • a baffled chamber 23 Attached to the output transfer conduit 7 is a baffled chamber 23, shown in more detail in Figure 4.
  • a baffled chamber consists of a number of baffles 55 placed directly in the fluid flow, for the purpose of inducing turbulence in the fluid and adding to the back pressure effect within the transfer conduit 7 against the output valve 4.
  • the pressure applicator system 2 is a modified form of hydraulic pump which is air operated.
  • Compressed air 30 is delivered though an air conduit 8 into the air motor 22, passing through an air filter 9, a regulator 10, an air flow oil reservoir 12, a 1 /4 turn air valve 13, and an air inflow port 16 to the air motor 22.
  • the air filter 9 is used to drain water from the compressed air supply 30.
  • the regulator 10 controls the air pressure, which is displayed on the pressure gauge 1 1 . Minute oil droplets are introduced into the compressed air supply 30 as the air flows over an oil reservoir 12. This is used to lubricate the air motor 22.
  • the air motor cycles the piston 20 forward and backward as a result of the compressed air flow.
  • the number of strokes of a piston 20, as shown in Figure 3, is controlled by the 1 /4 turn air valve 13.
  • a dial is placed on the 1 /4 turn air valve 13 at a 90 degree incremental basis.
  • the valve is fully closed and no air flows to the air motor 22.
  • the valve is fully open and the full volume and force of the compressed air 30 is delivered to the air motor 22.
  • the air motor is off.
  • the motor 22 is at full speed.
  • the 1 /4 turn air valve 13 is therefore the speed controller of the pressure applying device 2, acting to cycle the piston 20 at its highest number of strokes.
  • Pre-mix 40 is passed through the apparatus illustrated in Figure 2 and is pressure treated as the piston 20 strikes downward during its up and down displacement cycle within the pressure applicator housing 2.
  • the valves 3 and 4 may be closed while the piston 20 is applying pressure to the pre-mix 40 trapped between the valves in the compression chamber 1.
  • the valve action may be adjusted to provide a semi-continuous flow, wherein check valves are used in both the inlet valve 3 and the outlet valve 4.
  • check valves are used in both the inlet valve 3 and the outlet valve 4.
  • both valves 3 and 4 may be closed for a period of time, allowing full pressure to build up within the compression chamber 1 .
  • the output valve 4 opens and the pressure within the chamber 1 causes the pressure treated pre-mix 40 to flow from the compression chamber 1 out of the device through the output transfer conduit 7, into the baffled chamber 23, finally exiting the system through exit conduit 24.
  • Figure 3 is a partly cut-away view of the piston pressure applying device 2.
  • Compressed air 30 enters the device at the air input port 1 6 and acts to force the piston 20 downward through a nose housing 42 into the compression chamber 1 .
  • pre-mix 40 has been delivered past the input valve 3 which is shown as a spring loaded check valve.
  • the pre-mix is trapped at this point between input valve 3 and output valve 4, which is a female outflow spring loaded check valve.
  • the piston 20 is forced downward by the air motor 22 it strikes the surface of the pre-mix 40 and generates a shock wave through the pre-mix.
  • a series of seals and gaskets are placed along the compression chamber to provide isolation of the pre-mix from the rest of the pressure applicator's assemblage. These are illustrated at 21 and 50 in Figure 3.
  • the output valve 4 In a conventional hydraulic pump, as the piston 20 drove downward, the output valve 4 would immediately open and allow the flow to move onward. In this case, the output valve 4 is designed to have higher tension on its check valve springs so that more pressure is required to force its opening. The result is that as the piston 20 comes downward into the compression chamber 1 , both the input 3 and output 4 valves are kept in a closed position. This allows the piston 20 to generate the shock wave as it hits the pre-mix 40. If solenoid valves are used, the timing of the opening and the closing of the valves, especially the output valve 4, is adjusted to maximize the generation of the pressure shock wave generated by the piston 20 action against the pre-mix 40. The time during which the pre-mix 40 is exposed to the pressure build up within the compression chamber 1 is determined by the opening of output valve 4 and this is tied to the stroke rate determined by the 1/4 turn air valve 13.
  • the treated material now called the "post-mix" 44, flows into a baffled chamber 23 and finally out of the system through an exit channel 24.
  • the baffled chamber 23 impedes the fluid flow enough for back pressure to build up against the output valve 4, keeping it closed even longer with just a step down in fluid flow channel diameters.
  • Figure 4 shows an embodiment of the baffled chamber 23.
  • the housing 54 of the chamber 23 is sufficiently long to allow turbulence to build up in the post-mix 44.
  • the length of the chamber may be varied to accommodate various treatment effects.
  • Pressure treated fluid (post-mix) 44 enters the chamber 23 through inflow nozzle 57 which is contained within the inner diameter 56 of the hollow chamber housing 54.
  • baffles 55 are placed along the interior length of the chamber 23 to further create turbulence as the pressure treated fluid passes through the chamber.
  • the baffles are actually a series of rings with projecting tabs as shown in the cross- section of Figure 5. These tabs stick from the rings into the fluid flow, acting like baffles, and creating enhanced turbulence and shear within the pressure treated fluid 44.
  • piston 20 acts to generate cavitation within the compression chamber 1 as the piston 20 generates its pressure shock wave effect.
  • the shock wave acts to liberate trapped gases within the pre-mix, thereby generating heat.
  • the heat energy so released is thought to be a major factor in the modification of the physical properties of the fiber material within the pre-mix 40.
  • the turbulence in chamber 23 also causes a back pressure effect upon the output check valve 4 shown in Figures 2 and 3.
  • This back pressure effect causes a delay in the opening of the output check valve 4 and thereby enhances the length of time that pressure is applied to the target sample.
  • the pressure treated fluid 59 exits the chamber 23 through outflow nozzle 58.
  • the inflow tubing leading to the chamber 23 is of smaller diameter than the outflow of the compression chamber 1 of the pressure applicator device 2. This step down in flow diameters helps to create the pressure shock wave effect within the compression chamber 1 by keeping output check valve 4 closed for a longer period of time.
  • the outflow from the baffled chamber 23 is carried from the apparatus through outflow channel 24, and can then be delivered to a collection tank, or directly to a drying apparatus.
