Opfindelsen angår et apparat til tørring af termolabile produkter med tendens til klumpning under anvendelse af et cylinderformet hvirvellagsapparat med tørrrerum og afkølet tilstrømningsindretning.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for drying thermolabile products with a tendency to lump using a cylindrical vortex layer with drying chamber and cooled inflow device.
Ved de i praksis kendte tørringsapparater har de vægge, som omgi-5 ver tørrerummet, tilstrømningsbunden i hvirvellagstørrere samt indbygninger i tørrerummet til mekanisk blanding i reglen en større temperatur end det materiale, som skal tørres. Ofte opvarmes tørrerens apparatdele ved igangsætningen op til indgangstemperaturen for tørringsmediet.In the practice of dryers known in practice, the walls surrounding the drying room, the flow bottom of fluidised bed dryers and the housings in the drying room for mechanical mixing generally have a higher temperature than the material to be dried. Often, the appliance parts of the dryer are heated up to the inlet temperature of the drying medium at startup.
10 Tørres der termolabile produkter, som desuden har tendens til klumpning, kan der som følge af berøring med de varme apparatdele fremkomme beskadigelser. Denne risiko er især akut under driften af tørringsanlæg, hvis tilførslen af det materiale, som skal tørres, som følge af forstyrrelser afbrydes eller mindskes stærkt eller såfremt dettes 15 indgangsfugtighed svinger stærkt.10 If thermolabile products are dried, which also tend to clump, damage may result from contact with the hot appliance parts. This risk is particularly acute during the operation of a drying plant if the supply of the material to be dried as a result of disturbances is severely interrupted or diminished or if its input moisture fluctuates strongly.
Ifølge DE-patentskrift 23.35.514 skal der med en speciel udformning af tilstrømningsbunden forhindres en berøring mellem denne og det materiale, som skal tørres. Under start eller i tilfælde af driftsforstyrrelser hindres en klumpning og en termisk beskadigelse af materia-20 let imidlertid ikke.According to DE-patent specification 23.35.514, with a special design of the inflow bottom, contact between the latter and the material to be dried must be prevented. However, during start-up or in case of operational malfunction, clumping and thermal damage to the material are not prevented.
Der kendes ingen tørrer, hvor temperaturen af de dele, som kommer i berøring med det materiale, som skal tørres, kan holdes vilkårligt under indgangstemperaturen for tørringsmediet, både under igangsætningen og under driften og ved driftsforstyrrelser.No dryers are known, where the temperature of the parts which come into contact with the material to be dried can be kept arbitrarily below the inlet temperature of the drying medium, both during start-up and during operation and in case of interruptions.
25 Termolabile materialer, som har tendens til klumpning, kan derfor ikke tørres uden en vis kvalitetsforringelse i de forhåndenværende apparater.Therefore, thermolabile materials which tend to clump cannot be dried without some deterioration in the quality of the existing apparatus.
I DE-offentliggørelsesskrift nr. 30. 25 924 afkøles støttebunden (tilstrømningsbunden) ved fordampning af en væske, som holdes på et be-30 stemt niveau, til beskyttelse af beholdervæggen, idet der fra den varme gas udtrækkes varmeenergi, som atter i hvivellaget tilføres det til tørring bestemte rislegods ved hjælp af varmevekslingsflader. Bortset - 2 -In DE Publication No. 30. 25,924, the support floor (the inflow floor) is cooled by evaporation of a liquid held at a determined level to protect the container wall by extracting heat energy from the hot gas which is again applied to the swivel layer. the dry goods destined for drying by means of heat exchange surfaces.

fra et kortvarigt anvendt, eksternt kølekredsløb, foreligger der ved normale driftsbetingelser ingen afkøling af det til tørring bestemte produkt, fordi der tilføres varmeenergi differentieret, trinvis og vel-doseret til det til tørring betemte produkt. Der forskydes varmeenergi 5 fra området ved støttebunden til hvirvellaget, hvorhos der fremtvinges tab.from a short-term external cooling circuit, under normal operating conditions, there is no cooling of the product intended for drying because heat energy is differentiated, incrementally and well-dosed to the product intended for drying. Heat energy 5 is displaced from the area at the support floor to the vertebral layer, forcing losses.
Målet med opfindelsen består i at udvikle et apparat til tørring, ved hvis benyttelse både under igangsætningen og under driften samt ved driftsforstyrrelser der forhindres en klumpning og en termisk beskadi-10 gelse af materialer, som har tendens dertil, og dermed en kvalitetsforringelse.The object of the invention is to develop an apparatus for drying, the use of which both during start-up and during operation as well as in operating disturbances, which prevents lumping and thermal damage of materials which tend to, and thus a quality deterioration.
Til grund for opfindelsen ligger den opgave at holde alle dele af tørreren, med hvilke det produkt, som skal tørres, kommer i berøring under tørringsprocessen, under den temperatur, som fører til klumpning 15 og til termisk beskadigelse.The object of the invention is to keep all parts of the dryer with which the product to be dried comes into contact during the drying process, below the temperature leading to lumping and thermal damage.
Dette gælder især for de vægge, som omgiver tørrerummet, for de i tørrerummet til mekanisk blanding tilstedeværende dele samt ved hvir-vellagstørrere tilstrømningsbunden ved igangsætningen, ved driftsforsty rrrel ser og delvis også under driften, hvor væggene og delene i ap-20 paratet næsten antager indgangstemperaturen for tørringsmediet.This is especially true for the walls surrounding the drying room, for the parts present in the drying room for mechanical mixing as well as for the fluidized bed dryers at the start-up, at operating controls and partly also during operation, where the walls and parts of the apparatus almost assume the inlet temperature of the drying medium.
Opgaven løses ifølge opfindelsen ved, at et apparat til tørring af termolabile produkter med tendens til klumpning under anvendelse af et cylinderformet hvirvellagsapparat med tørrrerum og afkølet tilstrømningsindretning er konstrueret således, at væggene i tørrerummet, ti 1-25 strømningsindretningen og en blandingsindretning er omgivet af rum,.som er udformet som hulrum eller som en indre ringformet samleledning, som føres stråleformet i en vinkel på 1° - 60° skråt opad til kanaler, som fører til en ydre samleledning, i form af stråleformet indefra og udad rettede dobbeltkanaler, som er ført parallelt med tilstrømningsbunderr, 30 og at hulrummene eller den indre, ringformede samleledning gennemstrømmes af et kølemiddel.The task is solved according to the invention in that an apparatus for drying thermolabile products with a tendency to clog using a cylindrical vortex layer with drying room and cooled inflow device is designed so that the walls of the drying room, the flowing device and the mixing device are surrounded by space. formed as a cavity or as an inner annular junction which is beamed at an angle of 1 ° - 60 ° obliquely upward to channels leading to an outer junction, in the form of beam shaped from the inside and outwardly directed double channels which are passed parallel to the inflow bottom, 30 and the cavities or the inner annular joint conduit flowed through a refrigerant.

og nedre åbning udad er forsynet med studse og en studs med et gennemstrømningsreguleringorgan, og at rummene har et lysmål mellem den ydre og den indre væg på mellem 5 mm og 50 mm og er opdelt i indbyrdes adskilte sektioner.and the lower opening outwardly is provided with studs and studs with a flow regulator, and the spaces have a light dimension between the outer and inner walls of between 5 mm and 50 mm and are divided into mutually spaced sections.
5 Det er kendetegnende for løsningen, at de stråleformet anbragte dobbeltkanaler munder således ind i et lodret, aksialt dobbeltrør, at de indre og ydre rør holdes sammen, og at der opstår et indre og et ydre rum, som er indbyrdes adskilte, samt at også de ydre kanaler hver rager ud over de indre kanaler og er lukket i deres øvre ende og åbne i 10 deres indre ende. Endvidere er apparatet udformet således, at det indre ved den nedre ende åbne rør i det aksiale dobbeltrør forneden rager u-den for det ydre, hvorhos den fremkomne ringspalte mellem det ydre og det indre rør i dobbeltrøret er lukket forneden, og at det ydre rør i dobbeltrøret ovenover sin nedre ende har åbninger og er anbragt indven-15 digt i en ringformet kanal. Mellem den øvre og nedre væg i kanalen og det ydre rør i dobbeltrøret er der anbragt en pakning.5 It is characteristic of the solution that the radially arranged double channels open into a vertical, axial double tube, that the inner and outer tubes are held together, and that an inner and outer space are formed which are mutually spaced, and that also the outer ducts each project beyond the inner ducts and are closed at their upper end and open at their inner end. Furthermore, the apparatus is designed so that the inner at the lower end open tube in the axial double tube below extends beyond the outer, where the resulting annular gap between the outer and inner tube of the double tube is closed below and that the outer tube the double tube above its lower end has openings and is arranged internally in an annular duct. A gasket is arranged between the upper and lower walls of the duct and the outer tube of the double tube.
Førend tørringsmediet og det materiale, som skal tørres, kommer ind i tørringsapparatet, ledes der et kølemedium gennem rummene, som omslutter væggene i og omkring tørrerummet. Gennem de rum, som omgiver 20 tørrerumsvæggene, strømmer kølemediet ind gennem den nedre studs og forlader det gennem den øvre. I de rum, som omslutter tilstrømningsindretningen, flyder kølemediet ind gennem studsene i den indre ringformede samleledning og ud gennem studsene i den ydre ringformede saml eled-ning. Kølemediet kommer endvidere ind i de rum, som omslutter frem-25 springene til mekanisk blanding, gennem studsene i den ringformede kanal, og det strømmer gennem de ydre rum i det lodrette, aksiale dob-beltrør, gennem de ydre rum i det stråleformet anbragte dobbelrør eller dobbelkanal er, deres indre rør eller kanaler og forlader dem atter gennem det indre rør i det lodrette, aksiale dobbeltrør. Volumenstrømmene 30 af kølemediet indstilles ved hjælp af gennemstrømningsreguleringsorganerne. Tilførslen af kølemediumstrømme afbrydes først, når der ikke mere befinder sig materiale, som skal tørres, i tørrerummet og der ikkeBefore the drying medium and the material to be dried enter the drying apparatus, a refrigerant is passed through the compartments which enclose the walls in and around the drying room. Through the compartments surrounding the 20 drying room walls, the refrigerant flows in through the lower studs and leaves it through the upper. In the spaces surrounding the inflow device, the refrigerant flows in through the studs in the inner annular junction and out through the studs in the outer annular junction. The refrigerant further enters the compartments which enclose the mechanical mixing projections through the studs in the annular duct, and it flows through the outer compartments of the vertical, axial double tube, through the outer compartments of the beam-shaped double tube. or duct, their inner tube or ducts, leaving them again through the inner tube in the vertical, axial double tube. The volume streams 30 of the refrigerant are adjusted by the flow control means. The supply of refrigerant streams is interrupted only when there is no more material to be dried in the drying room and no

Apparatet ifølge opfindelsen forklares ved hjælp af et udførelseseksempel, hvorhos den dertil hørende 5 fig. 1 viser en tørrer set forfra, og fig. 2 viser en snitgengivelse af fig. l.The apparatus according to the invention is explained by means of an exemplary embodiment in which the associated FIG. 1 is a front view of a dryer, and FIG. 2 is a sectional view of FIG. l.
Der tørres 250 kg/h rå, revne kartofler, som med ca. 60 masse-% fugtighed kommer fra en centrifuge, til 10 masse-% restfugtighed. Som 10 tørringsmedium anvendes 5000 m3/h luft med 403K indgangstemperatur og 0,001 kg vand/kg tør luft indgangsfugtighed. Luften køles ned til 333K og når en vandoptagelse på 0,038 kg/kg. Temperaturen af de revne kartofler måles til 328K i hvirvel laget. Diameteren i tørrerummet 1 andrager forneden 800 mm. Den udvider sig opad til 1600 mm ved 2500 mm høj-15 de.Dry 250 kg / h of raw, cracked potatoes, which with approx. 60 mass% moisture comes from a centrifuge, to 10 mass% residual moisture. As 10 drying medium, 5000 m3 / h of air with 403K inlet temperature and 0.001 kg of water / kg of dry air inlet humidity are used. The air is cooled down to 333K and reaches a water uptake of 0.038 kg / kg. The temperature of the cracked potatoes is measured to 328K in the vortex layer. The diameter of the drying room 1 is below 800 mm. It extends upwards to 1600 mm by 2500 mm high-15.
Ifølge opfindelsen opnås kølingen med vand på 293K således, at temperaturerne i alle vægge i og omkring tørrerummet forbliver langt under 343K - 348K. I dette temperaturområde begynder en klumpning af kartoflerne og derpå, fx. ved varmeophobning i tilstrømningsbunden, en 20 termisk beskadigelse. I rummet 2, som omslutter tørrerumsvæggen, strømmer. 0,3 m3/h kølevand gennem gennemstrømningsreguleringsorganet 13 og studsen 9. Det forlader atter dette rum gennem studsen 10. Med indstillet gennemstrømningsreguleringsorgan 12 føres 0,2 m3/h kølevand ind i rummet 3, som omslutter den mekaniske blander, først gennem studsen 7 i 25 den ringformede kanal 16, og derfra gennem åbningerne 17 ind i det ydre rum i det lodrette, aksiale dobbeltrør 18 og videre ind i de ydre rum i de stråleformet anbragte dobbelrør eller dobbeltkanaler 19. Det opvarmede kølevand forlader atter dette rum gennem det indre rør og studsen 8. Mellem den ringformede kanal 16 og det lodrette aksiale dobbeltrør 30 18 befinder der sig en nedre pakning 15 og en øvre pakning 14. Gennem rummet 4, som omslutter fremspringene til mekanisk blanding, strømmer der 0,1 m3/h kølevand gennem gennemstrømningsreguleringsorganet 11, - 5 -According to the invention, the cooling is achieved with water of 293K such that the temperatures in all walls in and around the drying room remain well below 343K - 348K. In this temperature range, a clumping of the potatoes begins and then, e.g. by heat accumulation in the inflow, a 20 thermal damage. In the room 2, which encloses the drying room wall, flows. 0.3 m3 / h of cooling water through the flow regulator 13 and the socket 9. Again, this space leaves through the socket 10. With the adjusted flow regulating means 12, 0.2 m3 / h of cooling water is introduced into the space 3 enclosing the mechanical mixer, first through the socket 7. in the annular duct 16, and thence through the openings 17 into the outer compartment of the vertical axial double tube 18 and further into the outer compartments of the radially disposed double or double duct 19. The heated cooling water again leaves this compartment through the interior pipe and the plug 8. Between the annular duct 16 and the vertical axial double pipe 30 18 there is a lower gasket 15 and an upper gasket 14. Through the chamber 4, which encloses the projections for mechanical mixing, 0.1 m3 / h of cooling water flows through the flow regulating means 11, - 5 -
