1 Claim. 1
This invention relates to a machinefor heating or chilling liquids.
In the processing of fluid dairy products it is desirable that the materials be heated quickly and cooled quickly so that harmful bacterial action in the product may be controlled. It is, therefore, an object of this invention to provide a heat exchange device which can be used to either heat or chill the materials to the desired temperatures in a' continuous process.
In the processing of oleornargarine it is desirable that the material be reduced to a relatively cool temperature below its normal melting point from its liquid emulsion state so that the product will congeal and may be worked and formed of convenient shapes and sizes for packaging. It is, therefore, an object of this invention to provide a heat exchange device which can be used to reduce the temperature of liquid margarine emulsion to the desired temperature and simultaneously work the cooled emulsion in a continuous process.
Another object of this invention is to provide an improved rotor engaging in a cylinder and having scraping blades mounted thereon in a manner whereby the adhering material will be scraped from the cylinder, and the blades being arranged in staggered relation along the length of the rotor will subjectthe material to be worked and mixed into a homogeneous mass.
Another object of this invention is to provide an improved rotor having scraping blades which will be centrifugally held in contact with the surface of the cylinder, the blades being loosely mounted in slots formed in the rotor which are of such shape that the rotor can be easily inserted into the cylinder from one end by swinging the blades radially inwardly into substantial contact with the inner sides of the slots.
Another object of this invention is to provide an improved rotor having scraping blades which are easily inserted onto the rotor and which are prevented from moving out of proper position and jamming between rotor and cylinder when rotor is engaged but motionless in cylinder by the proximity of the inner cylinder wall to the rotor.
Another object of this invention is to provide an improved mounting for the rotor.
With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specifications, and then more particularly pointed out in the appended claim.
In the drawings,
and I2.
Figure 1 is a detail end elevation of a chilling machine constructed according to an embodiment of this invention,
Figure 2 is a sectional view taken on the line 2-2 of either Figure 1 or 3,
Figure 3 is a sectional view taken on the line 33 of Figure 2,
Figure 4 is a detail side elevation of the device,
Figure 5 is a detail side elevation, partly broken away, of the rotary element embodied in this invention,
Figure 6 is a sectional view taken on the line 6-6 of Figure 2,
Figure '7 is a fragmentary transverse section showing the scraper blade mounting,
Figure 8 is a view similar to Figure 7, showing a modified form of rotor,
Figure 9 is a fragmentary transverse section showing another form of scraper blade and a modified form of rotor constructed according to an embodiment of this invention.
Referring to the drawings, the numeral I0 designates generally a cylinder which is adapted to be disposed in a horizontal position, and has secured to the opposite ends thereof heads II The cylinder ID has rotatably mounted therein a rotor generally designated as E4 which is formed of an elongated round body I5 having extending from the opposite ends thereof stub shafts l3 and I6.
The body I5 is formed with a plurality of longitudinally extending circumferentially spaced apart slots I'I within which scraper blades I8 are adapted to be loosely mounted. The slots I"! are substantially tangentially arranged so that the scraper blades I8 will be disposed on substantially a tangent to the circle of the inner surface of cylinder IO. By providing the slots I! the blades I8 may be mounted in these slots of the body l5, and the assembly then inserted into the cylinder In from one end thereof. When the rotor is inserted initially into the cylinder ID, the blades l8 are rocked inwardly with the inner edges as a fulcrum, and at this time they will freely pass into the cylinder ID.
The rotor I4 is rotated at a relatively rapid rate so that the blades I8 will be centrifugally forced outwardly into scraping contact with the inner surface of cylinder l0. Preferably, as shown in Figure 5, the blades are arranged in a staggered series so that these blades will serve as a mixing means to mix the material into a homogeneous mass.
The shafts I3 and I6 are journalled in bearing heads I9 and 20. respectively, which are secured to the heads II and 12 by fastening means 2|. The bearing heads l9 and 20 engage about the stub shafts l3 and 16 at a point outwardly from packing and sealing glands 22 and 23 which are carried by the end members II and I2 respectively. By providing the sealing glands inwardly of the bearings the lubricant used for lubricating the bearings I9 and 20 will be held against contact with any of the liquid material which is passing through the cylinder H1.
The body l of the rotor I4 is disposed in a po sition spaced slightly from the inner surface of the cylinder I0, as indicated at 24, thereby providing a restricted passageway through which the material is adapted to pass. The head l2 has secured thereto an intake pipe 25 for conducting the liquid material into the cylinder It at one end thereof, and at one end to the rotor M which is spaced from the inner side of the head 12, to provide an intake chamber 26. The material is exhausted from the cylinder [0 at the opposite end thereof, being exhausted through outlet pipe 27 communicating with end chamber 28 formed between the head i I and the adjacent end of the rotor M.
In order to provide a means whereby a heat exchange medium may be circulated around the material to be heated or cooled, I have provided a heat exchanging chamber 29 which is formed by positioning an inner jacket 30 about the cylinder I0. An outer jacket 3! is disposed concentrically about the inner jacket 30 and is heat insulated therefrom by heat insulating means 32. The two jackets 30 and 3! are secured to end members or heads 33 which are disposed about the cylinder l0 adjacent the opposite ends there of and which are adapted to be sealed in any suitable manner with respect to the cylinder ID.
The heat insulating casing formed by the jackets 30 and 3| and the insulating means 32 is communicated with a heat exchange medium by means of inlet pipe 34 which is adapted to be connected to a source of the heat exchange medium, and an outlet pipe 35 returns the heat exchange medium to the supply source.
Referring now to Figure 8 there is disclosed a modified form of rotor embodying a hollow rotor member Ma which is formed with longitudinal V-shaped channels Ila. Scraper blades |8a are loosely mounted in the channels Ha and are centrifugally forced outwardly upon rotation of the rotor- Me. It will be understood that a driving motor or driving member such as a pulley or the like may be secured to stub shaft I6 for rotating the rotor M at a predetermined speed of rotation.
Referring to Figure 9 there is disclosed another form of rotor embodying a hollow rotor member Mb which is formed with longitudinal rectangular slots i'lb. Scraper blades 1812 are loosely mounted in the channels lib and are free to swing radially inward to permit easy insertion of rotor into cylinder and centrifugally outward to make scraping contact with the inner surface of cylinder 10.
The blades l8b are formed with V-shaped outer scraping edges 36 so that these blades can be inverted when inserted into the slots I'Ib so that these blades cannot be incorrectly inserted.
In the use and operation of this device, the material, such as liquid oleomargarine emulsion, is discharged under pressure into the intake chamber 26 of cylinder l0. As rotor l4 rotates in the cylinder 10 and as the material passes lengthwise through space 24 between rotor l4 and cylinder I0, the scraper blades I8 will scrape the adhering material on the inner surface of cylinder [0 and will mix the material into a homogeneous mass. The material is forced under pressure through space 24 and is discharged through outlet pipe 21. A cooling medium is circulated through cooling chamber 29, the cooling medium entering chamber 29 through intake pipe 34 and exhausting through outlet pipe 35. With a structure as hereinbefore described, the material, such as oleomargarine, may be chilled in a continuous operation and may be kept in a sanitary condition through the medium of the inner packing glands 22 and 23 which are positioned inwardly from the bearings 19 and 20. I
I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.
What I claim is:
In a heat exchange means comprising a cylinder, a rotor in said cylinder and of lesser diameter to provide a fluid passage between said rotor and said cylinder, said rotor being formed with a series of staggered longitudinally extending slots, each inclined to the radii of said rotor in the direction of rotation thereof and each being divergent in the direction of the open end thereof and having an arcuate closed end, a blade loosely mounted in each slot and extending the full length thereof, the thickness of each blade being substantially equal to the width of the slot at its base and the base of each blade being arcuate conforming to the arcuate closed end of its associated slot to permit operating thereof under the influence of centrifugal force whereby the blade edge may engage the inner wall of said cylinder to scrape the same when the rotor is activated, and inlet and outlet means for said cylinder, said blade edge comprising a straight side and an inclined side, the inclined side being positioned away from the direction of rotation of said rotor.
