Definitions
- the invention relates to a plant for the production of powdered sugar according to the Preamble of claim 1.
- the eddy current mill shown in the brochure corresponds structurally and functionally essentially the mills according to DE-AS 23 53 907 or DE-196 03 627 C2.
- a detailed description of one developed by the applicant This type of mill can be found in German patent application 100 55 130.0 which is expressly referred to.
- Such mills have one on the inlet side Opening that allows the inflow of air.
- EP 0 007 037 a mill can be found a pneumatic opening into the collecting container Delivery line, air in and out and a filter arrangement.
- the destroyed crystal surface is the first amorphous.
- the amorphous sugar tends to get into the crystalline state reconvert.
- the amorphous surface is very hygroscopic and picks up even from relatively dry air, e.g. at a relative humidity of 10%, water on.
- the absorbed water lowers the activation energy, which leads to the initiation recrystallization is required.
- the higher the humidity the faster the Recrystallization.
- the moisture absorbed by the amorphous sugar exceeds the water absorption capacity of crystalline sugar. From the recrystallized Therefore, excess moisture is released. This leads to an increase the moisture content of the air in the spaces between one finely ground sugar is formed.
- the trapped air can be much wetter than the ambient air inside Storage room. Due to the increased moisture, the surface of the sugar crystals dissolved. This creates bridges between the sugar crystals, which after the Drying out of the sugar hardens, so that the crystals form lumps connect with each other.
- the invention has for its object a system according to the preamble of Claim 1 to create, in which the finely ground sugar in recrystallized form can be removed and stored and transported without further treatment is.
- the system according to the invention is by blowing water vapor into the pneumatic conveying line or creates an air humidity directly into the mill, in which the recrystallization time is shortened, so that the re-installation in Collection container takes place and is essentially complete when the maximum fill level is reached.
- the injection into the delivery line or directly into the Mill has the advantage that it takes place at a point where the fine-grained material is washed particularly intensively by the moist air.
- the finely ground sugar is recrystallized by compressed air jets are blown in at the bottom, loosened continuously or intermittently. It can the released excess moisture can escape unhindered and the finely ground sugar cooled by the evaporative cooling to room temperature become.
- the invention uses a mixing head which is in the Mixed technology has proven itself for a long time.
- a programmed control of the Compressed air supplied enables, in particular a compressed air supply in the form periodic air blasts at specified time intervals.
- a silo (not shown) is turned into a discharge device, e.g. one Cell wheel lock, taken from sugar, whose grain size is less than about 2 mm is.
- the sugar is fed in a steady flow through a conveyor, e.g. a Screw 1, fed via a feed box 2 to a mill 3, which is further below in individual is described.
- An air flow, the fresh air and in the cycle Recirculated air can contain a suction pipe 4 and Silencer 5 sucked into the inlet box 2, accompanies the sugar on the Path through mill 3 and transports the resulting fines through a pneumatic delivery line 6 in a collecting container 7.
- a nozzle 8 With a nozzle 8, the with a steam generator, not shown, is connected at a short distance behind the mill 3, dry steam is blown into the delivery line 6.
- the nozzle 8 can also be directed directly into the mill 3, in deviation from FIG. 1.
- the fine material is partly by gravity, partly by one housed in the cylindrical upper part 9 of the collecting container 7 Filter assembly 10 separated from the air stream.
- the one freed from the fines Clean air is drawn off by a radial fan 11 and at least partially via expelled a chimney 12 into the atmosphere.
- a motor driven actuator 13 By means of a motor driven actuator 13, a partial flow of clean air via a branch line 14 are returned to the intake pipe 4.
- the separated fine material forms a pile in the collecting container 7.
- a mixing head 15 which is at the bottom Edge of a truncated cone, narrowing downward lower part 16 of the Collecting container 7 is attached, at short intervals of e.g. 20 seconds Compressed air blown in intermittently, as with the pneumatic mentioned above Mixers known per se.
- the fines With each impact, the fines are loosened and on the Wall of the rotationally symmetrical collecting container 7 like a helix torn up. This creates a rotating dust fountain, which follows the Pressure surge breaks down. Before the fines become dormant again The next pressure surge follows.
- the required compressed air is supplied to the mixing head 15 via a compressed air line 17 a compressed air reservoir 18 supplied.
- the air supply is via an actuator 19 controlled, which by a control unit 20 according to a predetermined program is operated.
- the compressed air reservoir 18 is by a not shown Compressed air line or fed by a compressor.
- a second, in the drawing, not shown, is provided, which is also in the lower area is equipped with nozzle channels for blowing compressed air.
- the two collecting tanks can be separated by a pipe willow, not shown can be activated alternately, so that each of the one container from the Mill picks up incoming fines while the other is emptied.
- the mill 3 is mounted on a machine frame 21. It consists of one Housing 22, a stator 23, and a rotor 24.
- the housing 22 has one Bottom 25 and a cylindrical jacket 26 with a vertical cylinder axis.
- the Jacket 26 is provided with a discharge opening 27, which is tangent to the Jacket 26 connects the pneumatic delivery line 6.
- the stator 23 has the shape of a truncated cone tapering upwards. He sits like a lid on the housing 22 and is height-adjustable by means of screws 28. It is covered by an annular disc 29, which has a filling opening 30 for the grinds and encloses the sucked in air.
- the inner surface of the stator 23 is lined with a corrugated armor 31.
- a shaft 33 of the rotor 24 is in a bearing housing 32 fastened to the base 25 stored. It carries a pulley 34 at the lower end and is via a V-belt 35 driven by a motor 36 at high speed, which is next to the mill the machine frame 21 sits. The upper end of the shaft 33 is with the rotor 24 connected.
- This has a basic body consisting essentially of a Hub 36, a support ring 37 attached thereto, a cover plate 38 through a support cylinder 39 is supported on the support ring 37, a cylinder 40 on the underside of the support ring 37 is fixed, and an annular base plate 41, which is connected to the cylinder 40 and encloses the bearing housing 32.
- ribs 42 are attached to the underside of the base plate 41 fan blades 43.
- floor-like two ring-shaped tool carriers 44, 45 are fastened one above the other.
- intermediate ring 46 which is also connected to the cylinder 40 is.
- Base plate 41, lower tool carrier 45, intermediate ring 46, upper Tool carrier 44 and cover plate 38 are one above the other at equal intervals arranged.
- the outer diameters are the frustoconical stator 23 customized.
- Each tool carrier 44, 45 is provided with a plurality - e.g. thirty to forty-milling tools 47 equipped, both on the bottom and on the Top are arranged like a wreath at equal intervals on the circumference.
- each Grinding tool 47 has a rectangular one which rests against the tool carrier 44, 45 Base plate 48. On the two approximately radial, short sides is with the Base plate 48 each have a vertical grinding web 49 connected. The grinding webs 49 are rhomboid. The angle a between abutting edges is that Cone angle of the stator 23 adapted.
- the grinding tools 47 are in pairs Screws 50 immovably attached to the tool carriers 44, 45 so that everyone on the top seated grinding tool 47 on the bottom a grinding tool 47 is arranged exactly opposite.
- the outer edges of the grinding tools 47 form a narrow gap with the inner surface of the armor 31, the so-called Grinding gap.
- the width of the grinding gap is 28 using the set screws variable.
- FIG. 5 shows an annular mixing head 15, the only indicated frustoconical lower part 16 of the collecting container 7 is attached.
- the Mixing head 15 has an annular pressure chamber 52 which is rectangular in cross section and which via a connecting piece 53 or more evenly over the circumference Distributed such connection piece is connected to the compressed air line 17.
