1 Claim. l
The invention relates to cooking apparatus and more particularly to cookers for cooking various material by either the continuous or batch process and in which the material being treated is agitated during the cooking process.
The general object of the invention is to provide a cooker in which live steam may be introduced into the cooking chamber and a steam jacket surrounds the cooking chamber, and while the apparatus shown is particularly adaptable to the making of process cheese, it may be used for other cooking purposes. In such an apparatus problems of reinforcing the jacket space, anchoring the direct injection steam pipes, supporting the feed screw or screws and permitting of their ready removal, and securely clamping the top cover are present. Among the several features of the invention is a reinforcement for the lining and jacket comprising a stay bolt connection therebetween which allows freedom of movement between the lining and jacket when the rate of thermal expansion is not the same or when stresses occur in either.
Another feature of the invention is the anchoring of direct steam injection pipes to the lining at an angle to the cooker centerline and also at an angle to horizontal to assist in the movement of the material being treated and the connection of these pipes to the jacket by a flexible mounting.
Another feature of the invention is the mounting of the feed screw on a half sleeve bearing at one end and a bearing unit at the other end disposed outside the cooking area.
Another feature is the structure permitting' removal of the feed screw without disturbing the exteriorly located bearing and packing gland by a detachable coupling which also forms a section of the screw, with leakage around the shaft prevented by means of said packing gland.
Another feature of the invention is the means for clamping a removable cover in pressuretight relation with the lining and so that the cover may be mounted to swing from either side of the apparatus to meet installation conditions, it being noted that the sealing pressure is applied in the areas where the sealing surfaces are located and not on those parts of the cover where distortion might take place.
The invention consists in the above and other features hereinafter 'described and more particularly defined by claim at `the conclusion hereof.
In the drawings:
Fig. 1 is a side elevation view of a cooking apparatus embodying the invention, parts being broken away and parts being shown in section; l
Fig. 2 is a horizontal sectional View taken on the line 2-2 of Fig. 1
Fig. 3 is an enlarged detailed vertical sectional View taken on the line 3 3 of Fig. 1;

Fig. 9 is a vertical sectional view through an apparatus showing certain modifications.
Referring to the drawings, the numeral IIJ designates a frame in which the cooker and its drive mechanism are mounted. The cooker includes an outer jacket II formed of suitable sheet metal, such as stainless steel, with flanged tops I2 extending along its sides and a rounded bottom I3, this shell being connected, as by welding, at its ends to end plates I4 and I5, the end plate I5 having an opening I6 therein and being provided with spaced guides I1 for the mounting of a slidable valve plate I8 provided with a handle I9 and having an outlet opening 2Il therein to aline with opening I6. The lining is formed by a trough-like shell 2I of sheet metal, such as stainless steel, having side flanges 22 welded or otherwise suitably secured to the flanges I2 of the jacket shell and having either a single curved bottom in the case of a single screw, as shown in Figs. 1 to 3, or a double curved bottom, as shown in Fig. 9, in the case of a double feed screw, said lining being connected by welding to the end plates I4 and I5. The members forming parts of the frame I0 are welded or otherwise suitably secured either to the flanged portions of the jacket and lining or to the sides of the jacket. The jacket and lining or liner are reinforced by a plurality of stay bolt connections, one of which is shown in detail in Fig. 8 and comprises a plate 23 welded or otherwise xedly secured to the Outer side of the lining and carrying a U-shaped rod 24 whose transverse portion is slidably mounted in an opening 25 of a bolt 26 whose threaded shank 2l extends through the jacket and is held in tensioned engagement therewith by a washer 28 and nut 29 which parts are then welded together and to the outer surface of the jacket as indicated in Fig. 8. This type of reinforcing spacing means lbetween the jackets allows free movement between the lining and the jacket when the rate of thermal expansion is not the same and/or when stresses occur in either. l
Live'steamisfintroduced into' the liing'through steam "pipes '39, ea'ch 'of which 'projects down- Wardly at an angle to the center line of the cooker and forwardly at an angle to the horizontal, as shown in Figs. 2, 3 and 7, 'so`that the steam issues in a direction downwardly and toward the exit end of the machine which V"acts to assist in imparting a movemnttothe material in'etal f disks or-'plate's-SZ whose peripheral portion 3-3'is=`welde'd tothebuteriside of the-jacket seas -t'ofprovidea flexiblefmountingand allow movement between the lining and-tlfiejacket when vthe rate of thermal expansionI -isnot the 'same and/0r when stresses-'occur ineither. Each-of Ythe live fs'tearn'pipes`3`0 connect-supwith a steam supply fheader 35 through unioncouplings 'and branch pipe connections jSyeach branch -being provided with-a-shut off Avalve 31. llorheating the space' between the jacketand -thelninga steam pipe y'3'8"connect's throughv branches- 3'9with the interior of the I jacket and Jasimilar return connection 4!) provided. "The 4jacket steam is controlled Ithrough l'any suitable valve, Anot shown.
The cooker may be provided withon'e or -more rotatable 'feed screws-of thef'spiralight type 4l. The forward end of each feedfscre'wis 'journalled -a-half bearing-f42 carried byth'erear plate I 5. The front-vendiof-the'feedscrewhas a shaft portion 4"3 whichcarries -a coupling '44 having a f screw flight I E4E 'formed as 1 a '#part thereof. This Coupling isf' slidably morted on the A.Slaaf-t 43 ,5 but `may rbe securediin driving 'relation ltlierewith by a'taperfpinf'land isilike'wise secured lto a-proje'ct- Yingend 48 'of a drivenshaft by a taper pin 49, as "shown inFi'g. 4. The-'shaft `'48 is supported `vby bearings located iin -a bearing isupport 50 mo'unted on fran'ie l'. lieakag'efearoundf the shaft isrpreventedlby'fapaeking gland E l and sleeves 52 clamped against the gland 15| -by l bolts 153, Also 'as thepackingfglandl and the bearing fsuppoi't 50 are Vlocated-.outside of the f cooking chamber, they canbekept'eol,-clean, and do not have -to be disturbed in 'fthe removal of the vfeed screw. "The -s'haftl inf the caseof a single screw isv driven "from an 'electric Jmotor 554 connected 'to 1a gear lreduction C515 whoseishaft 756 vis connectedbya :chain and sprocketfdrivei'l with 4the-shaft 48. 4Where two feedlscrewsarefused; one ofthe screws 'is vdriven Yas just described'#andY the other has an intermeshing geared `connection -'(`not shown) with the-`shaft-48 buter-knownconstruction.
With the vrabove arrangement-removal of the pins 4l and 49 permits -Vth'e'coupling '44 to be slipped forwardly v"along the shaft 43 'so as to disengage it from'theshaft '4B-and thus permit lthewhole screw shaftlll 'to`be lifted upout'of the lining.
The' frontendof 'thec'ooking chamber is cov- "ered'by a feed hopper `58,"a`nd`the'remainder'of "thetop of the cooking chamber'is covere'dsb'y 'the'shetm'etal cover 58 whose central portion'at 'spaced intervals is provided with, upwardlyprojectingstuds' carrying nuts'Sl'by which cover frame members 62 are clamped to vthe 'top of the cover. The cover frame members at one end 62 extend down to provide an apertured ear adapted for mounting between spaced hinge ears 63, on either :side of 'the apparatus, these parts being secured together by a hinge pin 64. vThe ears 63 are provided with threaded shanks 5A'65 that prdtrude through `holes iin the flanges I2 "and 22 'anda flangedbr'acket Slsecured to the outer side of the jacket. The ear is clamped to `-the above named flanges by means of a nut 66 =or othersuitable means. The cover frame members 62 have cover 4clamping screws 68 adjustably Vmounted therein fand engaging the cover at D 'spaeed pointsover the anged sides I2 and 22 of 'the lining 'and jacket. These screws 68 are held:inpressurefengagement with the cover by a series of cover clamps, each comprising a bolt BShing'edly connected by the pin 'IG to the opposite set of ears 63 from that for the cover frame members 62-`and ada'ptedtobe swun'g'up between the 'forked end 51| o'f said :inem-ber 162 land 'be clamped to said member 62 in'this 'position by a nut 121 engaging awasher'l 3 and `provided with ahand'cr'ank extension '754. Asi noted above,lthe vapertured ends of ltheframemembers 62 and the bolts69 aire'interchang'eable with -eitherlset offe'ars 63,'solth-at-thecover may beanou'n'ted to swing -up'wardly toward 'fthe A right, Ia's Yshown in'FiglS, or by turninglthe arms L52 through one -hundredeightyLdegre'es'thel cover ma'ybe mounted `tofswing upwardly -to lthe left, as 'viewed in Fig. 3,2itbeing-noted@thatthe -studsil Vfare c'entrallyfdisposedrelative to the `screws BSian'dtlie Vears 63 on opposite sides 'of -the Tapp'aratus1.
