Definitions

  • the present disclosure relates generally to methods of extracting lactose from whey.
  • FIG. 1 is an embodiment of an apparatus suitable for use with the present disclosure.
  • the present disclosure relates to methods of extracting lactose from whey. Such methods may be used to obtain whey or whey solids with reduced amounts of lactose. High levels of lactose may be problematic to some individuals, such as those suffering from lactose intolerance.
  • the methods described herein may be used to produce whey or whey solids that are suitable for ingestion by those with lactose sensitivities. Methods disclosed herein may also be used to isolate lactose. Products formed by these methods are also disclosed herein.
  • whey is broadly used to refer to liquid byproducts of the manufacture of cheese or other dairy products.
  • whey may refer to liquid remaining after milk has been curdled and strained.
  • solids content refers to the proportion, by weight, of non-volatile material in the whey over the total amount of material in the whey. Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints.
  • a sample of whey is initially obtained in any suitable fashion, such as by straining milk that has been curdled.
  • Whey typically includes lactose, a disaccharide sugar.
  • lactose may be a solute in a sample of whey.
  • the sample of whey may be heated and slowly cooled. During the cooling stage, lactose may precipitate out of solution.
  • lactose may crystallize as the sample of whey is cooled.
  • the solid (e.g., crystallized) lactose may be removed from the liquid in any suitable manner.
  • the heterogeneous mixture formed upon cooling is centrifuged to pellet the solid lactose.
  • the liquid whey may then be decanted, thereby separating the solid lactose from the liquid.
  • Water may be removed from a sample of whey (e.g., processed or unprocessed whey).
  • a sample of whey may be placed in an evaporator and heated to evaporate off water in the sample.
  • Water may be removed from the sample to achieve a predetermined concentration of solids. For example, in some embodiments, water is removed until the whey has a solids content of between 10% and 80%, between 10% and 50%, between 10% and 30%, between 30% and 80%, between 50% and 80%, between 25% and 60%, or between 35% and 50%.
  • the sample of whey may be cooled.
  • Evaporation of water and subsequent cooling of the sample of whey may result in further precipitation of lactose. Stated differently, evaporation and subsequent cooling may cause lactose crystals to form.
  • whey that has been concentrated by the removal of water may be further processed to separate precipitated lactose from a liquid portion of the whey.
  • the precipitated lactose and the liquid portion of the whey may be placed on one or more filter screens.
  • the screen(s) include a plurality of apertures that are sized to allow liquid to pass through the screen(s) while retaining precipitated lactose as a retentate on the filter screen(s). In this manner, an operator may obtain both a lactose-enriched retentate on the filter screen(s) and a lactose- depleted filtrate.
  • a plurality of filter screens may be used to filter the lactose from the liquid portion of the whey.
  • a plurality of filter screens are arranged in a stacked configuration. More particularly, the filter screens may be arranged such that screens of increased porosity (i.e., having relatively large apertures) are disposed above screens of decreased porosity (i.e., having relatively small apertures). In this manner, as the concentrated whey mixture is placed on the top screen of the plurality of screens, the whey mixture may pass through the screens, with each screen removing smaller lactose-enriched aggregates than the screen directly above it. In this fashion, lactose aggregates (e.g., crystals) of various sizes may be collected.
  • lactose aggregates e.g., crystals
  • screens of differing porosities may be used to filter solid lactose from a liquid portion of a whey concentrate.
  • pore size may vary from 900 microns to 20 microns.
  • a first (e.g., top) screen may have a porosity of 900 microns
  • a second screen may have a porosity of 500 microns
  • a third screen may have a porosity of 300 microns
  • a fourth screen may have a porosity of 200 microns
  • a fifth screen may have a porosity of 00 microns
  • a sixth screen may have a porosity of 50 microns
  • a seventh (e.g., bottom) screen may have a porosity of 20 microns.
  • one or more screens may shake or vibrate as the concentrated whey mixture is filtered. Vibrating the one or more screens may cause the mixture to move on the surface of the screen. Such movement may decrease clogging of the pores of the filter screen, allow different portions of the mixture to contact the surface of the filter screen, and/or increase the speed of filtration.
  • one or more high-frequency vibrating screens may be used.
  • between 50% and 95%, between 50% and 80%, between 50% and 65%, between 65% and 95%, between 80% and 95%, or between 65% and 80% of the lactose in the concentrated whey mixture may be recovered on the filter screens.
  • the lactose precipitate e.g., lactose crystals
  • the lactose precipitate that is recovered as retentate on the one or more filter screens may be between 80% and 95% dry solids (i.e., have a water content of between 5% and 20%). Due to the relatively low water content of this lactose retentate, further drying may be accomplished in a cost- effective manner.
  • the filtering system 100 may also be referred to as a rotary vibrating sieve, sieve shaker, or vibro separator.
  • the system 100 incorporates circular unitary gyratory filter screens used to separate mass composition of solids from solids, and liquid from solid, and for gradation of materials as per particle size. This is accomplished by vibrating the screens in three different planes along the vertical axis by means of a specially designed vibration electric motor 78 having off-centered weights at the top and bottom end of a motor shaft.
  • the system 100 includes a shield 102 or top cover with a feeding inlet 104.
  • the shield 102 may be coupled to a first housing 106 through use of a clamp 108.
  • a first outlet 1 10 communicates with a first interior 1 12 defined by the first housing 106.
  • a first filter screen 1 14 separates the first interior 1 12 from a second interior 1 16 which is defined by a second housing 1 18.
  • a second outlet 120 communicates with the second interior 1 16.
  • a second filter screen 122 separates the second interior 1 16 from a third interior 124 which is defined by a third housing 126.

  • the above-recited elements rest on a platform 170 which is coupled to a plurality of springs 172.
  • the springs 172 are coupled to a base 174 which supports the system 100.
  • a motor housing 176 is coupled to the platform 170 and supports the vibration electric motor 178.
  • the vibration electric motor 178 vibrates the screens 1 14, 122, 130, 138, 146, 154, and 162 in three different planes along the vertical axis.
  • the motor 78 includes a top weight 180 which causes vibration in the horizontal plane and causes the material to move across the screen towards the periphery.

  • the whey mixture is introduced into the inlet 104, and the whey mixture passes through the filter screens 1 14, 122, 130, 138, 146, 154, and 162.
