Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor: fig. 1 viser i perspektiv et apparat ifølge opfindelsen, delvis gennemskåret, fig. 2 og 3 henholdsvis et aksialsnit og et radialsnit gennem det i fig. 1 viste apparat, og fig. 4 delvis opskåret og i perspektiv et udsnit af rotoren i fig. 2 og 3.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which: 1 is a perspective view of an apparatus according to the invention, partially cut away; FIG. 2 and 3 respectively an axial section and a radial section through the one shown in FIG. 1, and FIG. 4 is a partially cutaway perspective view of the rotor of FIG. 2 and 3.

Apparatet omfatter en beholder 11 med en cirkelcylindrisk sidevæg 12, som er lukket med endevæggen 13. Aksialt i beholderen 11 er lejret en roterbar radialvæg eller rotor 14, som strækker sig radialt ud mod sidevæggen 12 og støder op mod denne og endevæggene 13. Radialvæggens 14 kanter kan eventuelt være forsynet med et tætningsorgan, som sikrer tæt anlæg og hindrer gennemstrømning fra den ene side til den anden.The apparatus comprises a container 11 having a circular cylindrical side wall 12 which is closed by the end wall 13. Axially in the container 11 is mounted a rotatable radial wall or rotor 14 which extends radially towards the side wall 12 and abuts against it and the end walls 13. The radial wall 14 Optionally, edges may be provided with a sealing means which ensures tight abutment and prevents flow from one side to the other.

Radialvæggen 14 er lejret på en aksel 15, som omfatter to koncentriske rør, nemlig et ydre rør 15A og et indre centralrør 15B.The radial wall 14 is mounted on a shaft 15 comprising two concentric tubes, namely an outer tube 15A and an inner central tube 15B.

Det ydre rør 15A er lejret i hensigtsmæssigt tætte lejer 16 i endevæggene 15. Det er desuden ført ud gennem den øvre endevæg, hvor det bærer en remskive 17, eller et lignende koblingsorgan, og gennem den nedre endevæg, hvor det ved hjælp af en hensigtsmæssig glidekob-ling 18 er forbundet med et rør 19, som kan tjene som udløbsrør. Centralrøret 15B er på tilsvarende måde ført ud fra det ydre rør 15A ved beholderens 11 overside og med en glidekobling 20 forbundet med et rør 21 som kan tjene som indløbsrør. Rørenes 15A og 15B forbindelser med beholderens 11 indre er beskrevet nedenfor.The outer tube 15A is housed in suitably tight bearings 16 in the end walls 15. It is further extended through the upper end wall where it carries a pulley 17, or a similar coupling means, and through the lower end wall where it is supported by an appropriate slide coupling 18 is connected to a pipe 19 which can serve as outlet pipe. The central pipe 15B is similarly extended from the outer pipe 15A at the upper side of the container 11 and with a sliding coupling 20 connected to a pipe 21 which can serve as an inlet pipe. The connections of tubes 15A and 15B with the interior of the container 11 are described below.

Som det især fremgår af fig. 4 er radialvæggen 14 fremstillet med bølgestruktur eller korrugeringer i radialretning med vekslende render 22 og ribber 23, som strækker sig ind til akselen 15. Ved den viste udførelsesform er radialvæggen 14 fremstillet som et enkelt lag og ribberne på den ene side vil derfor danne render på den anden.As can be seen in particular from FIG. 4, the radial wall 14 is made with a wave structure or radial corrugations with alternating grooves 22 and ribs 23 extending to the shaft 15. In the embodiment shown, the radial wall 14 is made as a single layer and the ribs on one side will therefore form grooves of the other.

På den ene side af radialvæggen 14 findes en åbning 24 i det ydre rør 15A, som munder ud i bunden af hver rende 22 på denne side. Tilsvarende findes der på den modstående side åbninger 25 i centralrøret 15B ud i bunden af renderne 22 på denne side. Hulrummet mellem centralrøret 15B og det ydre rør 15A er tætnet mod denne side af radialvæggen ved hjælp af en aksialt og radialt fortløbende væg 26, som forbinder de to rør, idet radialvæggen er ført ind til og forankret i céntralrøret 15B. Renderne 22 på denne side er desuden dækket med en blænde 27, således at der dannes en udløbsspalte 28 med stigende bredde ud fra centralrøret 15B. Det er hensigtsmæssigt at dimensionere 3 148172 denne udløbsspalte således, at dens bredde er proportional med kvadratet af afstanden fra aksen.On one side of the radial wall 14 is an opening 24 in the outer tube 15A, which opens at the bottom of each channel 22 on this side. Similarly, on the opposite side are openings 25 in the central tube 15B at the bottom of the troughs 22 on this side. The cavity between the central tube 15B and the outer tube 15A is sealed to this side of the radial wall by an axially and radially extending wall 26 connecting the two tubes, the radial wall being inserted into and anchored in the central tube 15B. The gutters 22 on this side are additionally covered with an aperture 27 so that an outlet gap 28 with increasing width is formed from the central pipe 15B. It is convenient to size this outlet gap so that its width is proportional to the square of the distance from the axis.

I fig. 4 er der nederst vist en blænde 27', som efterlader radialt forløbende spalter 28*, som øges i tæthed og/eller bredde ud fra centrum. Også denne spalteudformning kan dimensioneres således, at man opnår proportionalitet mellem åbningsarealet og kvadratet af afstanden fra aksen.In FIG. 4, an aperture 27 'is shown at the bottom leaving radially extending slits 28 * which increase in density and / or width from the center. Also, this gap design can be dimensioned so as to obtain proportionality between the opening area and the square of the distance from the axis.

Remskiven 17 ved beholderens 11 overside står over en drivrem 29 i forbindelse med en motor 30.The pulley 17 at the upper side of the container 11 stands over a drive belt 29 in connection with a motor 30.

Beholderen kan desuden forsynes med udstyr for eksempelvis opvarmning, tilførsel af tilsætningsstof, tryk- og temperaturmåling.The container can also be equipped with equipment for, for example, heating, supply of additive, pressure and temperature measurement.

Virkemåden for apparatet er følgende:The operation of the device is as follows:

Der tilføres doseret mængde masse, såsom foderstoffer, som skal varme- og trykbehandles, gennem tilførselsrøret 21. En sådan masse vil i de aktuelle tilfælde, f.eks. ved formalet slagteriaffald, være tilstrækkelig flydende til at kunne pumpes. Bortførelsen af masse vil bevirkes og styres ved rotation af radialvæggen (fig·3). .Dosed amount of mass, such as feed which is to be heat and pressure treated, is fed through the feed tube 21. Such mass will, in the present case, e.g. for ground slaughterhouse waste, be sufficiently liquid to pump. Mass removal will be effected and controlled by rotation of the radial wall (Fig · 3). .

Radialvæggens 14 hastighed indstilles således, at en omdrejning svarer til råstoffets opholdstid. Eksempelvis vil et anlæg med kapacitet 1 m^/time råstof for opholdstid 30 min. kunne have et volumen på 0,5 nr5, og radial væggens hastighed være 2 omdrejninger/ time. Massens ophold i beholderen 11 er således lig med radialvæggens omløbstid, som er fastlagt af motorens 30 rotationshastighed og kraftoverføringens udveksling. Trykket i massen vil kunne styres ved hjælp af en ventil i udløbsledningen.The speed of the radial wall 14 is adjusted such that a rotation corresponds to the residence time of the raw material. For example, a plant with a capacity of 1 m 2 / hour raw material for residence time 30 min. could have a volume of 0.5 nr5 and the speed of the radial wall be 2 rpm. Thus, the residence of the mass in the container 11 is equal to the radial wall turn-around time, which is determined by the rotational speed of the motor 30 and the transmission of the power transmission. The pressure in the mass can be controlled by means of a valve in the outlet line.

Massens konsistens vil i de fleste tilfælde, hvor det er nødvendigt, kunne justeres ved tilsætning eller ekstraktion af væske, således at de ønskede driftsbetingelser opnås.In most cases, the consistency of the pulp will be adjustable by the addition or extraction of liquid so that the desired operating conditions are achieved.

Apparatet, som er beskrevet ovenfor, vil kunne modificeres på en række punkter, i første række med hensyn til radialvæggens udformning. I stedet for den viste korrugerede form kan den være opbygget med flere plane lag. Forudsætningener, at radialvæggen udformes således, at alle massepartikler efter tilførsel til beholderen forbliver i ro i beholderen, d.v.s. at der ikke sker nogen strømning i massen.The apparatus described above may be modified at a number of points, first and foremost with respect to the design of the radial wall. Instead of the corrugated shape shown, it may be constructed with several planar layers. Assumptions that the radial wall be designed so that all mass particles after application to the container remain at rest in the container, i.e. that there is no flow in the mass.

Endvidere er det muligt at variere proportionerne på beholderen og radialvæggen. Det er særlig aktuelt at gøre diameteren på det ydre rør 15B større, først og fremmest i de tilfælde, hvor der stilles strenge krav til ensartet behandling.Furthermore, it is possible to vary the proportions of the container and the radial wall. It is particularly relevant to increase the diameter of the outer tube 15B, especially in cases where strict requirements for uniform treatment are made.

Ved en alternativ udførelsesform kan tilførsel og bortførsel af 4 148172 masse ske fra samme ende af beholderen. Beholderen kan også forsynes med flere end In radialvæg, men tilførslen og bortførslen af masse vil da blive vanskeligere.In an alternative embodiment, feeding and removal of pulp can be effected from the same end of the container. The container can also be provided with more than In radial wall, but the loading and removal of mass will then become more difficult.

Et sådant apparat kan benyttes til en række formål ved behandling af nærings- og foderstoffer. Det er særligt aktuelt at benytte den som holdecelle, f.eks. ved pasteurisering og sterilisering af næringsmidler.Such an apparatus can be used for a variety of purposes in the treatment of nutrients and feed. It is particularly relevant to use it as a holding cell, e.g. by pasteurization and sterilization of foods.

Opfindelsen kan udnyttes i forbindelse med stoffer, som kan gøres pumpelige, og som skal holdes under et bestemt tryk, en bestemt temperatur, en bestemt pH-værdi eller under bestemte enzymatiske forhold en vis tid. Ved hjælp af organer, som roterer med radialvæggen kan enkelte af disse betingelser, såsom temperatur og pH-værdi, ændres i løbet af behandlingstiden.The invention can be utilized in conjunction with substances which can be made pumpable and which must be kept under a certain pressure, temperature, pH or under certain enzymatic conditions for a certain time. By means of means which rotate with the radial wall, some of these conditions, such as temperature and pH, can be changed during the treatment time.
