Definitions

  • a malting vessel has a vertical tube set within it, with its ends spaced from the top and bottom of the vessel, and there is a feed screw or a gas stream active in the tube so that a circulation of contents may be set up throughout the vessel, at will. Air or other gas at controlled temperature, humidity and pressure can be injected into, the vessel at any time.
  • a feed screw it preferably has a special construction, with a conically flared lower end, the pitch of the screw in this region being progressively inversely proportional to its diameter.
  • a novel method of malting involves the setting up of a circulation of grain in a vessel in such a way that part of the grain batch is rising while another part is falling, gas being optionally injected at least into the part of the circulation where grain is falling.
  • the present invention on the other hand provides for a continuous or intermittent circulation throughout the batch in the vessel during times when control is required, and for the injection of gas or gases of desired temperature and humidity into the grain either during its circulation or when stationary so that all parts of the batch of grain are kept under the correct conditions during the process.
  • all parts of the batch get, over a period of time, an exposure to standardized and controlled malting conditions.
  • This invention has for an object the provision of apparatus and methods whereby the malting of any grain, particularly barley, may be carried out under controlled conditions with high efflciency, that is to say with great evenness of temperature and other conditions in and surrounding the grain being treated.
  • apparatus for malting grain includes a vessel containing an inner vertical tube having ends spaced from the top and bottom of the vessel, elevating means to move grain in opposite vertical directions inside and outside the inner tube and means for passing gas into the vessel.
  • the elevating means may be pneumatic, for example. a noz zle directed to discharge gas up the inner tube and served by a high-pressure gas inlet or may be mechanical, for example, a feed screw located within and coaxial with the inner tube, with control means for the temperature and humidity of the gas used for the pneumatic lift, if provided, and for the gait or gases passed into the vessel.
  • a rotatable agitator may be provided at the bottom of the vessel, and there may be further controllable inlets, erg. gas or additives.
  • aerating legs arranged to be served with gas at any desired temperature, humidity and pressure and to discharge it into the grain being treated.
  • the legs may extend over at least the greater part of the length of the inner tube.
  • Inwardly directed air nozzles arranged to discharge air into the grain to prevent arching or bridging thereof.
  • a feed screw preferably is formed around a central shaft which has a conical skirt at its base portion, the base portion of the screw being formed around the conical skirt and fitting within a corresponding conical flared portion of the inner tube.
  • the base portion ofthis screw may have a pitch which is progressively inversely proportional to the square of the diameter of the conical skirt.
  • I provide a method of malting grain which includes maintaining grain circulation in avessel by lifting part of the grain at one portion of the vessel and at messme time allowing part of the grain to fall in another to format circulation.
  • the method may include passing gas into the vessel during the circulation to enter at least that part of the grain which is falling in the vessel.
  • the vessel and method may be used either solely for the aerobic stage of malting or for any or all stages of any method of malting known to me.
  • a charge of barley may be placed in the vessel, may be steeped in the vessel and subjected to aerobic and/or anaerobic phases in the vessel, the circulation and aeration facilities of the vessel being used as required during the aerobic modification phase or phases or during both aerobic and anaerobic phases.
  • the malting vessel is a more costly piece of capital equipment than'the simple containers and vessels which would be required for steeping and/or initiating germination, the grain may be held in other vessels of a simpler construction during those stages and transferred to the present malting vessel only for certain other stages, e.g. its aerobic and/or anaerobic phases.
  • FIG. 1 is a diagrammatic side elevation of a first embodiment
  • FIGS. 2 and 3 are detail sectional views of parts of that embodiment.
  • FIG. 4 is a diagrammatic side elevation of a second embodiment.
  • the vessel is a closed-ended cylindrical drum set with its main axis vertical.
  • the vessel is made in three portions, the center portion 1 being a hollow open-ended cylinder having end flanges 2, 3, a top' closure 4 of the vessel being attached to flange 2 by a like flange 5, and a bottom frustoconical portion 6 of the vessel being attached to flange 3 through a hollow ring portion 7 which will be more particularly described later.
  • the bottom end of the frustoconical section 6 is closed by a closure plate 8.
  • the top closure 4 bears a mounting 9 for an electric motor 10 and also an inlet pipe 11 for grain and a narrower inlet pipe 12 for any additives that may be required to be used. There is also a wide gas outlet 13 fitted with a closure and release valve (not shown).
  • a valved outlet pipe 14 leading to a floater box for receiving dust and other solid matter which it may be desired to remove from the vessel, and a first gas gallery 15 which has a gas inlet 16.
  • a first gas gallery 15 which has a gas inlet 16.
  • the ring 7 forms a second gas gallery and has a gas inlet 20.
  • a sight glass 21 equipped with an internal wiper (and other sight glasses may be provided at suitable points over the whole of the ves sel), an arch-breaking air jet 22 and a discharge port 23 equipped with a power-operated openable closure door which is gastight when closed.
  • a bearing boss 24 receiving the lower end of a shaft which extends coaxially with the motor 10, a drain outlet 25 and a gas withdrawal outlet 26 which has a valved drain 27 in a branch.
  • a shaft 28 of the drive motor 10 is coupled through a flexible coupling 29 to a hollow shaft 30 which extends as far as the bearing boss 24 in the baseplate of the vessel.
  • the paddle 34 is offset from the axis of rotation of the screw to sweep outwardly any grain falling inside the conical skirt 32.
  • the conical skirt 32 terminates at the level of the lowermost revolution of the screw and reinforces its radially inner edge.
  • the paddle 34 joins the skirt 32 adjacent the shovel part 33 of the screw.
  • the screw 31, together with its portion which surrounds the conical skirt 32 works inside a stationary inner tube 35 which is supported within the vessel by stays and spacers such as 36, 37, and has at its bottom end (FIG. 2) an outwardly flaring tube part 38 which has narrow elongate slots 39.
  • the portion of the screw 31 which surrounds the conical skirt 32 has a conformation such that the pitch of the screw is at any one time inversely proportional to the square of the diameter of the skirt 32 which forms its inner boundary. This is to ensure that material, as it is drawn up outside the skirt 32 and inside the flared tube part 38, is not axially compressed as it progresses into regions of successively lesser diameter. We call this part of the assembly, the scroll. Along the length of the cylindrical part of the tube 35 the screw pitch is constant.
  • the shovel portion 33 of the screw 31 is reinforced on its radially inner side by the extreme bottom end part of the skirt 32 and on its outside it has an upstanding edge lip 40 so that it forms a shovel for scooping up grain lying on the bottom plate of the vessel.
  • This bottom plate has an upper perforated decking 41 which has narrow slits of a size to permit drainage of liquid downwardly without permitting grain to pass.
  • the perforations allow also for the passage of gas through the base.
  • the bottom of the conical part 38 of the tube 35 is spaced above the decking 41 of the baseplate 8, and the shovel 33 works within that spacing.
  • the paddle 34 displaces outwardly any grain which falls inside the radius of the shovel, and gas jets 2 are positioned around the perimeter of the upper decking 41, but in the outside wall of the conical portion 6 of the vessel, ready to be used should any bridging or cavitation occur in the region of the gap between the decking 41 or portion 6 and the tube portion 38.
  • a small nozzle 45 can be fed with gas or liquid through an inlet 46 in the bushing construction 24 so as to wash or blast off grain which might be in the area of the bottom portion of the shaft 30, and in the baseplate 8 there is a drainage outlet to permit flow-away of any liquid passing through the decking 41, and gas suction outlet 26 will be used to assist in the rapid displacement of one type of atmosphere by another when need be.
  • the outlet door 23 has a guillotine slide plate 47 powered by, for example, a hydraulic ram, which slide plate when closed forms a gastight seal with the bearings in which it runs.
  • the ring 7 which acts to secure together the part 1 and part 7 of the vessel and acts also as a gas gallery for the input of gas into the vessel.
  • the ring is generally of channel construction, the base 50 of the channel being a cylinder and its sidewalls 51 and 52 being parallel, horizontally disposed and bolted to flange 3 of the vessel 1 and the corresponding flange of the portion 6, respectively.
  • the mouth of the channel section which is thereby disposed inwardly of the vessel is covered by some foraminate covering 53 for permitting gas to pass freely but prevent grain from accumulating in the gallery.
  • air gallery 15 is similar insofar as a foraminate member is provided and an annular gas channel around the circumference of the vessel 1.
  • the hollow shaft may have perforations in it so that aeration of the grain may be continued even as it is being moved upwardly by the screw within the casing 35.
  • barley or other grain which may be as harvested or which may be in any suitable stage of the malting process is admitted through the charging pipe 11. It falls into the gap between the inner tube and the outer wall of the vessel and charging is continued until a desired amount of grain is in the vessel. The depth of grain in such a vessel is very considerable. Experimentally, I have worked with grain depths of 7 feet or more, and a charge of 2 tons weight (when containing its desired 44-50 percent of moisture.)
  • the grain was admitted in its harvested condition, it is steeped in the vessel, water being added through inlet 12 at a controlled temperature. Aeration during steeping may be carried out. A water circulation may be set up by using the drain outlet 25 and inlet 12. After the steep, an aerobic germination period follows, and during this phase the motor 10 drives the shaft 30 and hence the screw 31 in rotation in such a sense as to lift grain from the bottom of the vessel to the top.
  • the motor 10 may be of variable speed, and be controlled in its operation through a conventional control 42 by temperature or other condition sensing means 43 in the vessel.
  • a charge of 2 tons weight being circulated at a rate so that there is one complete changeover each 5 minutes will suitably be supplied with air at a rate of approximately 800- 1,000 cu. ft./min.
  • the vessel may also be used during an anaerobic phase or a resteeping process in which the rootlets are killed-the grain may be left static during this phase, the atmosphere inside being changed either actively or by virtue of respiration for one of CO or other nontoxic nonrespirable gas (or water in the case of resteeping), or the circulation of grain may be continued.
  • CO or other gas may be passed into the vessel through gas galleries 7, 15.
  • the circulation facility may be used at any stage. When it is used, it assists a controlled and evenly dispersed supply of gas to the grain.
  • malting additives may be provided, and water may be added in liquid form as well as by humidification of the gas.
  • the gas used is dependent on the stage in the malting at which it is used, and may be air and/or carbon dioxide, or may be a mixture of carbon dioxide and another nontoxic nonrespirable gas.
  • the second embodiment of the invention uses as elevating means, instead of the screw 31, an air current.
  • This embodiment is shown diagrammatically in FIG. 4.
  • the chamber 60 is fabricated in stainless steel and has a column about 10 feet high and 4 feet 6 inches in diameter, of generally cylindrical form, the lower part 61 of the chamber tapering inwardly.
  • an inner tube 62 Located vertically within the chamber and coaxial therewith is an inner tube 62 corresponding to casing 35, the bottom end 63 of which is about 9 inches from the bottom of the chamber and about 12 inches in diameter, while the top end 64 is about 2 feet from the top of the chamber and about 9 inches in diameter.
  • the inner tube is tapered in the bottom portion, the tapered part 65 being about 2 feet 6 inches to 3 feet long.
  • a deflector having upper 66 and lower 67 conical deflecting surfaces, and above this is an inlet 68 for the grain.
  • This is formed in the top wall of the chamber and is provided with means for ensuring an airtight seal.
  • a water inlet 12 having valve means to control the flow of water and a gas outlet 70, fitted with a pressure release valve that may be set to allow the escape of gas from the chamber at atmospheric or other predetermined pressure. Gas received by the outlet can be recirculated, as will be described.
  • Thermometers, pressure gauges and glass inspection windows are provided in the wall of the chamber where necessary.
  • Gas galleries 7, 15, are provided as before, the wall of the chamber being provided with grilles which constitute the inner wall of the galleries and permit gas to pass into the chamber.
  • the number and disposition of the galleries may be varied as required.
  • there may be gasifying legs consisting of a number of vertical tubes 75, blind at their lower ends and apertured along their length (the apertures may be larger or more frequent towards the blind end), arranged vertically approximately midway between the walls of the outer chamber 60 and inner tube 62.
  • the legs are connected via a gas-distributing ring 76 to an exterior gas supply through gas inlet 77.
  • Such gasifying legs may be provided in the first embodiment described.
  • a gas nozzle 78 is located in the middleof the bottom wall of the chamber and extends vertically up into and coaxial with the inner tube 62, the nozzle projecting about 12 inches into the lower end ofthis tube.
  • the nozzle is served with high-pressure gas (e.g. air at a pressure of the order of 3() psi.) from a suitable external s0urce'79 at a predetermined or controllable temperature.
  • high-pressure gas e.g. air at a pressure of the order of 3() psi.
  • the bottom wall 80 of the chamber has an aperture communicating with a closable discharge outlet 81, and above the bottom wall of the chamber there is a mechanical agitator 82 consisting of radially extending arms arranged to be rotatable by means 83 below the chamber and including a suitable source of power such as an electric motor, whereby the radial arms may be caused to rotate and sweep across the bottom of the chamber and facilitate movement of the grain.
  • the bottom wall of the chamber also is provided with an outlet 84 for liquor with a suitable control valve.
  • the gas nozzle 78 may be so mounted as to be adjustable in height relative to the lower end of the inner tube.
  • barley or other grain which may already have been steeped is charged through the inlet 68 onto the upper surface 66 of the deflector and is filled to the required extent.
  • Water at a desired temperature may be introduced into the chamber in a predetermined quantity for adjustment of the moisture content.
  • an aerobic phase gas at the desired temperature and pressure and which may be recycled from the outlet 70 is introduced through the ducting system via the upper and lower galleries 7, 15, to pass through the grilles into the body of the grain and out through the gas outlet.
  • the high pressure gas inlet to the nozzle 78 is opened and a current ofgas moving at the desired speed, pressure, and temperature passes up the inner tube 62.
  • Grain at the bottom tapered part 61 of the chamber 60 is forced radially inwardly as it falls under gravity so that it comes underneath the lower end 63 of the inner tube 62. where it is entrained by the gas stream from the nozzle and begins to be carried up the innertube, its place being taken by more grain passing in radially at the bottom, while the elevated grain is deflected by the lower surface 67 of the deflector at the top 64 of the inner tube so as to pass radially outwardly and fall upon the grain at the top ofthe chamber.
  • a circulation of the grain is thus built up and in a short time a steady rate of flow will have been obtained so that the grain is moving up the interior of the inner tube continuously and is deflected outwardly so as to fall down into and fill the space between the outside wall of the inner tube 62 and the wall of l the chamber 60. This continues until the chamber has been then recirculating down round the outside of the inner tube and is eventually again passed up the inner tube.
  • This recirculation may be continuous throughout a given phase of treatment of the grain, or may be interrupted.
  • the grain is thus subjected to various influences which will dissipate local rises in temperature.
  • the grain in the inner tube is being subjected to gas of a predetermined temperature served through the nozzle;
  • the falling grain is subjected to the passage of the gas from the grilles in the upper and lower gas galleries, whereby gas is caused to pass constantly through the body of the grain; and
  • the constantly moving grains are continuously mingled.
  • the agitator 82 may be employed further to mingle the grains. The first-mentioned of these is a facility not afforded by the first embodiment.
  • the outlet aperture in the bottom of the chamber is opened and if and when required the agitator is employed to assist efficient emptying of the vessel through the outlet aperture.
  • the agitator 82 may be a rake with upstanding teeth, or it may be of blade form.
