MIXING DEVICE
A device for the mixing fluid media. The device is a bladeless mixer. The device comprises a hollow body with at least a single inlet opening in its bottom and at least a single outflow region in its side. The device is rotated at a speed at which the media due to centrifugal forces enters the device's hollow cavity via the inflow opening or unit. The media is discharged from the cavity through one or more outlet units or openings in the sides or in the top of the device. During mixing the media does not rise above the level of the undisturbed media.
1 . A method for mixing biological components, the method comprising:
a. receiving at least one first ingredient and at least one second ingredient in a vessel with a mixing body disposed within the vessel; and
b. mixing the at least one first ingredient and the at least one second ingredient by spinning the mixing body, wherein the mixing body comprises at least one inlet, at least one outlet and a cavity, and wherein in response to spinning the mixing body, the at least one first ingredient and the at least one second ingredient enter the cavity via the at least one inlet, and exit the cavity via the at least one outlet thereby mixing the at least one first ingredient and the at least one second ingredient.
2 . The method according to claim 1 , wherein the at least one inlet has a filter.
3 . The method according to claim 1 , wherein the at least one second ingredient is dispersed higher in the vessel when the body has a first portion having a first diameter and a second portion having a second diameter and the diameter of the second diameter is greater than the first diameter.
4 . The method according to claim 1 , wherein in response to spinning the mixing body a vortex is created in the body.
5 . The method according to claim 1 , wherein prior to mixing, in step a, the at least one first ingredient and at least one second ingredient have a first height and wherein during the mixing step in step b, the at least one first ingredient and at least one second ingredient also have a first height.
6 . The method according to claim 1 , wherein prior to mixing, in step a, the at least one first ingredient is in the cavity, in the at least one inlet, and in the at least one outlet and the at east one second ingredient is the at least one inlet and not in the cavity or in the at least one outlet.
7 . The method according to claim 1 , wherein during the mixing step, step b, the at least one first ingredient is in the cavity, in the at least one inlet, and in the at least one outlet and the at least one second ingredient is in the cavity, in the at least one inlet, and in the at least one outlet.
8 . The method according to claim 1 , further comprising removing a sample of the mixed at least one first ingredient and at least one second ingredient from the vessel.
9 . A mixing device for mixing biological components, comprising:
a rotatable body, the body comprising at least one first portion and at least one second portion adjacent the first portion, wherein the second portion has a circumference greater than the first portion, the body having at least one wall defining a cavity;
the at least one first portion having an end with an inlet opening coaxial with an axis of rotation for the rotatable body and communicating with the cavity for introducing at least one first ingredient into the cavity;
the at least one first portion having an array of spaced-apart first peripheral openings that communicate with the cavity;
the at least one second portion having an array of spaced-apart second peripheral openings that communicate with the cavity,
wherein the rotatable body is configured during rotation while at least partially submerged to draw in the at least one first ingredient through the inlet opening and into the cavity, creating a flow through the cavity and out through the first and second peripheral openings.
10 . (canceled)
11 . The mixing device of claim 9 , wherein the inlet opening is configured to receive the at least one first ingredient and at least one second ingredient into the cavity, and the first and second peripheral openings are configured to expel a mixture of the at least one first ingredient and the at least one second ingredient from the cavity.
12 . (canceled)
13 . The mixing device of claim 11 , wherein the at least one second ingredient is more dense, heavier, more viscous and combinations thereof than the at least one first ingredient.
14 . The mixing device of claim 9 , wherein the at least one first ingredient does not change.
15 . The mixing device of claim 11 , wherein at a first time point the at least one second ingredient is at a first level and at a second time point the at least one second ingredient is at a second level, wherein the second level is higher than the first level.
16 . A mixing device for mixing biological components, comprising:
a rotatable body, the body comprising at least a first portion having a first diameter, at least a second portion having a second diameter and at least one wall defining a cavity, wherein the second portion is adjacent the first portion and the second diameter is greater than the first diameter;
the at least one first portion having at least one inlet communicating with e cavity; and
the at least one second portion comprising spaced-apart peripheral openings and respective non-radial passages that communicate with the cavity,
wherein the rotatable body is configured to be positioned with at least the inlet submerged in liquid and caused to rotate, thereby drawing the liquid through the inlet and into the cavity, and expelling the liquid from the cavity through the non-radial passages and the peripheral openings.
17 . The mixing device of claim 16 , wherein the first portion further comprises at least one outlet for communicating with the cavity.
18 . The mixing device of claim 16 , wherein the cavity further comprises baffles.
19 . The mixing device of claim 16 , wherein the body comprises a lid.
20 . (canceled)
21 . The mixing device of claim 16 , wherein the at least one outlet is positioned at about a 5-175° angle with the at least one inlet.
22 . The mixing device of claim 16 , wherein the mixing device is formed as a single piece.
23 . The mixing device of claim 9 , wherein the first peripheral openings and the second peripheral openings are aligned with each other in a longitudinal direction.
24 . The mixing device of claim 9 , wherein the first peripheral openings comprise three peripheral openings that are equally spaced from each other in a circumferential direction.
25 . The mixing device of claim 9 , wherein the second peripheral openings comprise three peripheral openings that are equally spaced from each other in a circumferential direction.
