Den foreliggende opfindelse angår en fremgangsmåde til kontinuerligt under tryk at hydrolysere de ved* f jerkræopartejdniiig opnåede biprodukter, .og et apparat til udøvelse af fremgangsmåden.The present invention relates to a process for continuously hydrolyzing the by-products obtained by ferrous cryoparticle and an apparatus for carrying out the process.
Por at få udnyttet alle indtægtskilder ef det nødvendigt- for slagterier at nyttiggøre biprodukterne i størst mulig udstrækning. Hidtil har praksis i fjerkræslagterier været meget varierende med hensyn til graden af udnyttelse af biprodukter fra fjerkræet. Sådanne biprodukter og affaldsprodukter ophobes i et slagteri og må sædvanligvis fjernes daglig. Opsamlelige ikke-spiselige biprodukter, såsom blod, fjer og indvolde, udgør op til 30$ af alt slagtet fjerkræs levende vægt.It is important to utilize all sources of income if it is necessary for slaughterhouses to use the by-products as much as possible. So far, the practice of poultry slaughterhouses has varied greatly in the degree of utilization of poultry by-products. Such by-products and waste products accumulate in a slaughterhouse and usually need to be removed daily. Collectible non-edible by-products, such as blood, feathers and viscera, make up to $ 30 of the live weight of all slaughtered poultry.
Det er kendt i praksis at opsamle sådanne ikke-spiselige biprodukter og ved hydrolytisk nedbrydning af de indeholdte proteiner omdanne dem til fordøjeligt foder til fjerkræ og andre dyr. Indtil nu har en sådan hydrolyee af fjerkræbiprodukter været langsom og kostbar og har ikke givet det bedst mulige udbytte. Mange slagterier har derfor bortkastet eller bortgivet deres fjerkræbiprodukter uden at få noget financi-elt udbytte af dem.It is known in practice to collect such non-edible by-products and, by hydrolytic degradation of the contained proteins, convert them into digestible feed for poultry and other animals. Up to now, such hydrolyze of poultry by-products has been slow and expensive and has not yielded the best possible yield. Many slaughterhouses have therefore discarded or disposed of their poultry by-products without any financial benefit from them.
De kendte fremgangsmåder til omdannelse af ikke-spiseligt f jerkræmateriale er i almindelighed blevet udført som en chargevis fremgangsmåde, hvor materialet holdes ved en temperatur på omkring 120°C og et damptryk på ca. 2 kg/cm^ i et tidsrum på 1-1¾ time eller længere til nedbrydning af de spiselige organiske materialer deri. Ea sådan chargevis fremgangsmåde er langsom, tidskrævende og kostbar, således at omdannelse af disse uspiselige produkter til foder kun er blevet udført på store slagterier i udpræget fjerkræavlende områder.; Ydermere er det nødvendigt at udelukke luft fra hydrolysekammeret, eftersom oxidation af materialet let kan finde sted ved de forhøjede temperaturer og tryk, og denne har en skadelig indflydelse på kvaliteten af det færdige foder. Desuden har det færdige produkt uensartet kvalitet.The known methods for converting non-edible poultry material have generally been carried out as a batch method, wherein the material is maintained at a temperature of about 120 ° C and a vapor pressure of approx. 2 kg / cm 2 for a period of 1-1¾ hours or longer to decompose the edible organic materials therein. Such a method of charging is slow, time-consuming and costly, so that the conversion of these inedible products into feed has only been carried out at large slaughterhouses in distinctly poultry farming areas; Furthermore, it is necessary to exclude air from the hydrolysis chamber as oxidation of the material can easily take place at the elevated temperatures and pressures and this has a detrimental effect on the quality of the finished feed. Furthermore, the finished product has uneven quality.

Fra USA patentskrift nr.3-295*982 kendes en fremgangsmåde, hvor man kontinuert "behandler slagteriaffald for deraf at udvinde dels fedt og dels et stærkt proteinholdigt kødmel.US Patent No. 3-295 * 982 discloses a method of continuously treating butchers' wastes in order to extract both fat and a strong proteinaceous meal.
Det anvendte slagteriaffald er et stærkt fedtholdigt materiale, der kontinuert føres til en med sluser i begge ender lukket, skråtliggende trykbeholder, hvori det indførte materiale af en transportsnegl føres op til beholderens udløbsende. Behandlingen sker under damp- og vandtilledning ved en temperatur på 150-175°C· Ved behandlingen smeltes fedtet ud af affaldet og flyder sammen med vand ud af trykbeholderens lavest liggende ende, medens affaldets fedtfrie bestanddele af sneglen føres op til beholderens højest liggende ende, hvorfra det ledes til et tørreapparat. Fra tørreapparatet ledes det tørrede produkt til en snegl, hvor det oversprøjtes med vand, der er udskilt fra den blanding af fedt og vand, som er flydt ud gennem trykbeholderens nederste ende. Formålet med denné kendte kontinuerlige fremgangsmåde er først og fremmest at få udvundet den fedtmængde, der findes i affaldet, og dette sker under vandtilsætning.The slaughterhouse waste used is a highly greasy material which is continuously fed to a sloping sealed container with locks at both ends, in which the introduced material of a conveyor auger is fed to the outlet end of the container. The treatment is carried out under steam and water supply at a temperature of 150-175 ° C · During the treatment the fat is melted out of the waste and flows with water from the lowest end of the pressure vessel, while the fat-free components of the screw are fed up to the highest end of the container, from which it is led to a dryer. From the dryer, the dried product is passed to a auger where it is sprayed with water which is separated from the mixture of fat and water which has flowed out through the bottom end of the pressure vessel. The purpose of this known continuous process is first and foremost to recover the amount of fat contained in the waste and this is done during water addition.
Formålet med den foreliggende opfindelse er at tilvejebringe en fremgangsmåde og et apparat, hvor man ved en kontinuerligt gennemført behandling får omdannet forholdsvis fedtfattigt fjerkræslagteriaffald, der blandt andet indeholder fjer, til et ensartet fordøjeligt foder.The object of the present invention is to provide a method and apparatus in which, through a continuous treatment, relatively low-fat poultry slaughterhouse waste containing, inter alia, feathers is converted into a uniform digestible feed.
Ifølge opfindelsen opfyldes dette formål af en fremgangsmåde og et apparat, der er af den i indledningen til krav 1 henholdsvis 2 angivne art, og som er ejendommelig ved det i krav l's henholdsvis 2's kendetegnende del angivne.According to the invention, this object is fulfilled by a method and apparatus which are of the kind specified in the preamble of claim 1 and 2, respectively, and which are characterized by the characterizing part of claim 1 and 2 respectively.
I sammenligning med det fra det ovennævnte amerikanske patent-skrift kendte gennemføres ved fremgangsmåden og apparatet ifølge ansøgningen behandlingen af det anvendte affald under iagttagelse af tre forhold, der alle er nødvendige for at opnå et fordøjeligt foder ud fra fjerkræslagteriaffald, men som ikke kendes fra det nævnte patentskrift.Compared to the prior art U.S. Patent Specification, the method and apparatus according to the application carry out the treatment of the waste used under consideration of three conditions, all of which are necessary to obtain a digestible feed from poultry slaughterhouse waste, but which are not known from it. said patent.

Det tilførte affald befries ved sammenpresning for luft, hvis tilstedeværelse i hydrolysekammeret ville være skadelig for hydrolysen, og desuden for en væsentlig del af sit væskeindhold.The waste is released by compression for air, the presence of which in the hydrolysis chamber would be detrimental to the hydrolysis, and in addition to a substantial part of its liquid content.
Det sammenpressede materiale findeles umiddelbart før det indføres i hydrolysekammeret, og derved sikres en gennemgribende hydrolyse. Den væske, der sammen med luft er udpresset af det tilførte affald, kan ledes i doseret mængde, således at den sammen med den tilførte damp kan tilvejebringe optimale hydrolysebetingelser i hydrolysekammeret.The compressed material is comminuted immediately before it is introduced into the hydrolysis chamber, thereby ensuring a thorough hydrolysis. The liquid, which is compressed with air by the feed waste, can be fed in a dosed amount so that, together with the steam supplied, it can provide optimal hydrolysis conditions in the hydrolysis chamber.

Hydrolysen kan udføres ved et tryk på ca. 4,9 kg/cm og temperaturer på ca. 185°C og derover. Det har vist sig, at ved tryk på 4,9 kg/cm^ og mere og ved den tilsvarende mætningstemperatur og mere, er kvaliteten af det protein, der fås ved hydrolysen, høj. Fremgangsmåden, ifølge opfindelsen og det dertil hørende apparat muliggør fremstilling af et produkt, der har et større indhold af protein og en bedre kvalitet af dette og andre næringsstoffer og med et mere nøjagtigt kontrolleret fugtighedsindhold end de produkter, der hidtil er blevet fremstillet af fjerkræaffald.The hydrolysis can be carried out at a pressure of approx. 4.9 kg / cm and temperatures of approx. 185 ° C and above. It has been found that at pressures of 4.9 kg / cm 2 and more and at the corresponding saturation temperature and more, the quality of the protein obtained by the hydrolysis is high. The process according to the invention and the related apparatus enables the preparation of a product having a higher protein content and a better quality thereof and other nutrients and with a more accurately controlled moisture content than the products hitherto produced from poultry waste.
Ved højere "kvalitet" af produktet skal forstås et højere protein- og kulhydratindhold og et lavere fiber- og celluloseindhold. Ved hjælp af fremgangsmåden ifølge opfindelsen kan fremstilles et foderprodukt med et ensartet proteinindhold på over 80$ og - afhængigt af udgangsmaterialet - eventuelt over 90$.Higher "quality" of the product means a higher protein and carbohydrate content and a lower fiber and cellulose content. By means of the method according to the invention, a feed product having a uniform protein content of more than 80 $ and - depending on the starting material - may be more than 90 $.

På tegningen betegner 10 et hydrolyseapparat til hydrolyse under tryk af fibrøst fjerkræaffald i form af fjer, blod, indvolde og lignende. Hydrolyseapparat et 10 har et indføringsorgan 12 (fig. 1, 2, 4 og 5) og et udføringsorgan 14, der hver er forbundet med en trykbeholder, der danner et hydroly-sekammer 16. Det fibrøse materiale, der skal behandles, indføres i en tragtformet fødebeholder 18 på enhver egnet måde, såsom ved hjælp af et transportbånd 19. Det fibrøse materiale kan være voluminøst affald fra et fjerkræslagteri, såsom fjer og indvolde. Disse materialer, som indføres i fødebehol-deren 18, indeholder en væsentlig mængde væske, især vand og blod, og udgøres desuden af en stor del luftfyldte hulrum.In the drawing, 10 denotes a hydrolysis apparatus for hydrolysis under the pressure of fibrous poultry waste in the form of feathers, blood, viscera and the like. Hydrolysis apparatus 10 has an insertion member 12 (Figures 1, 2, 4 and 5) and an embodiment 14, each connected to a pressure vessel forming a hydrolysis chamber 16. The fibrous material to be treated is introduced into a funnel-shaped food container 18 in any suitable manner, such as by means of a conveyor belt 19. The fibrous material may be bulky waste from a poultry slaughterhouse such as feathers and viscera. These materials, which are introduced into the food container 18, contain a substantial amount of liquid, especially water and blood, and are additionally made up of a large portion of air-filled voids.
Por at nedsætte indholdet af væsker og luft i de fibrøse materialer komprimeres de på egnet måde med en transportsnegl 20, der drives af en motor 21 over en passende drivrem 22.To reduce the content of liquids and air in the fibrous materials, they are appropriately compressed by a conveyor screw 20 driven by a motor 21 over a suitable drive belt 22.
I den viste udførelsesform er transportsneglen 20 af typen med varierende stigning med progressiv mindre stigning hen-imod dens afgangsende, hvad der medvirker til komprimeringen af det fibrøse materiale. Det komprimerede materiale forlader transportsneglen 20 og går ind i en indgangspassage 23, der fortrinsvis bliver bredere i transportringen. I denne passage 23 har det fibrøse materiale antaget form af en tryk-tæk prop 24, der i det væsentlige er fri for luft, og en stor del af væsken er presset ud af materialet og ledt væk fra bunden af fødebeholder en gennem en væskeafgang 25.In the illustrated embodiment, the conveyor auger 20 is of varying pitch type with progressively smaller pitch toward its exit end, which contributes to the compression of the fibrous material. The compressed material exits the conveyor screw 20 and enters an entrance passage 23 which is preferably wider in the conveyor ring. In this passage 23, the fibrous material has taken the form of a pressurized plug 24 which is substantially free of air, and a large portion of the liquid is squeezed out of the material and passed away from the bottom of the food container one through a liquid outlet 25 .
Den ønskede hydrolyse foregår hurtigere med små partikler end med store partikler, og der er derfor anbragt en opriv- 5 1415*21 nings-, blandinga- og skæringsdel 28, der Bplitter proppen 24 op i små partikler. Til dette formål indeholder oprivnings-og blandingsdele 28 et antal rot erbare knive 29, der føres tæt langs den indre væg af delens hus ved hjælp af en passende drivmotor 30 og drivrem 31, Eftersom proppen 24 udgør et tryklukke i indføringsorganet 12, kan oprivnings- og blandingsdelen holde et egnet tryk og en egnet temperatur til indledning af hydrolyseprocessen. Til tilvejebringelse af tryk og temperatur kan en afmålt mængde hydrolysemiddel, såsom damp, tilføres til det indre af oprivnings- og bl åndings del en gennem en egnet dampindsprøjtningsindgang 32. Desuden kan alle de væsker, der skal anvendes ved hydrolysen, såsom de væsker, der opnås fra væskeafgangen 25 ved bunden af fødebe-holderen 18, i afmålte mængder føres ind i oprivningsdelen.The desired hydrolysis takes place faster with small particles than with large particles, and therefore a tearing, mixing and cutting part 28 which splits the plug 24 into small particles is arranged. For this purpose, tearing and mixing members 28 contain a plurality of rotatable knives 29 which are guided closely along the inner wall of the housing by means of a suitable drive motor 30 and drive belt 31, since the plug 24 constitutes a pressure closure in the insertion member 12, and the admixture portion maintains a suitable pressure and temperature to initiate the hydrolysis process. In order to provide pressure and temperature, a metered amount of hydrolyzing agent such as steam can be supplied to the interior of the tear and breath part through a suitable steam injection input 32. In addition, all of the liquids to be used in the hydrolysis, such as the liquids which obtained from the liquid outlet 25 at the bottom of the food container 18, in metered quantities is fed into the tear-off portion.
28's trykkammer gennem en rørledning 54, således at der fås et ønsket og kontrollerbart fugtighedsindhold.28's pressure chamber through a conduit 54 so as to obtain a desired and controllable moisture content.
Knivene 29 i oprivnings- og blandingsdelen 28 kan danne vinkler med hinanden og være aksialt i forhold til hinanden forskudte excentriske skiver, der hver har en ydre bueformet overflade 2ga, der følger den indre overflade i kammeret.The knives 29 in the tearing and mixing portion 28 can form angles with one another and be axially offset from each other by eccentric discs, each having an outer arcuate surface 2ga following the inner surface of the chamber.
Hver kniv 29 kan desuden have konkave sidevægge 29b, der afsluttes af skærende kanter 29c. Et par skærme 29d (fig.5) uden for knivene 29 beskytter en pakningssektion 37 i oprivnings- og blandingsdelen mod faste partikler af det fibrøse materiale.In addition, each knife 29 may have concave side walls 29b terminated by cutting edges 29c. A pair of screens 29d (Fig. 5) outside the blades 29 protect a gasket section 37 of the tear and mixing portion against solid particles of the fibrous material.
Det opsplittede og skårne materiale falder på grund af tyngdekraften gennem en indgangsåbning 38 (fig. 4), der er udformet i bunden af oprivnings- og blandingsdelen 28, ind i indgangsenden af hydrolysekammeret 16 via en åbning 46.The fragmented and cut material, due to gravity, falls through an inlet opening 38 (Fig. 4) formed at the bottom of the tearing and mixing portion 28 into the inlet end of the hydrolysis chamber 16 via an opening 46.
Hydrolysekammeret 16 er en trykbeholder, hvori væsken og det fibrøse materiale underkastes den hydrolyserende virkning af varme og vanddamp. Det har vist sig, at når fugtig vanddamp ved et tryk på omkring 7 k^cm^, føres ind i hydro lys ekammer et 16 via oprivnings- og blandingsdelen eller 141521 6 om ønsket gennem passende dampindgange 47,fås en effektiv behandling af fjerkræmaterialer i løbet af ca. 6 minutter. Hydrolysekammeret 16 er forsynet med passende blade eller omrørere 49 til bevægelse af materialet deri for at opnå den hurtigste hydrolyse, og disse blade 49 er skråtstillet for at drive materialet fremad i det rør, der udgør hydrolysekammeret. Bladene 49 er anbragt på en roterende aksel 50, der drives af en motor med variabel hastighed over en drivrem 52. Regulering af opholdstiden for materialet kan derfor let foretages ved samstyring af kammerets udtømningshastighed og variation af bladene 491 s rotationshastighed.The hydrolysis chamber 16 is a pressure vessel in which the liquid and the fibrous material are subjected to the hydrolysing action of heat and water vapor. It has been found that when moist water vapor at a pressure of about 7 k 2 cm 2 is introduced into hydro light chamber 16 via the tearing and mixing portion or, if desired, through suitable steam inlets 47, effective treatment of poultry materials in over approx. 6 minutes. The hydrolysis chamber 16 is provided with suitable blades or agitators 49 for moving the material therein to obtain the fastest hydrolysis, and these blades 49 are inclined to drive the material forward in the tube constituting the hydrolysis chamber. The blades 49 are arranged on a rotating shaft 50 driven by a variable speed motor over a drive belt 52. Therefore, adjustment of the residence time of the material can be easily accomplished by controlling the discharge rate of the chamber and variation of the rotation speed of the blades 491.
Om ønsket kan en dampkappe 48 omgive kammeret 16 for at bevare eller tilføre varme.If desired, a vapor jacket 48 may surround the chamber 16 to retain or supply heat.
Ved afslutningen af hydrolyseprocessen føres det behandlede materiale bort fra hydrolysekammeret med en bestemt udtømningshastighed. Trykket må derved nedsættes til atmosfæretryk, damp må fjernes,og materialet må tørres til brug.At the end of the hydrolysis process, the treated material is moved away from the hydrolysis chamber at a specific depletion rate. The pressure must thereby be reduced to atmospheric pressure, steam must be removed and the material dried for use.
Udtømning sker gennem en passage 62, der fører til indgangssiden af en afgangspumpe 65, der drives af en motor 66 med variabel hastighed. Pumpen 65 tjener som måleanordning til at regulere afgangshastigheden fra hydrolysekammeret 16.Drainage is effected through a passage 62 leading to the inlet side of a discharge pump 65 driven by a variable speed motor 66. The pump 65 serves as a measuring device for controlling the discharge rate from the hydrolysis chamber 16.
Pumpen kan reguleres til at afgive materialet ved et ønsket tryk, der er lavere end fødetrykket på indgangssiden. Pumpen 65 afgiver materialet til en egnet ledning 67. Da materialets temperatur er høj og det rådende tryk formindsket væsentligt, vil noget, om ikke alt, af det vand, der er blandet med produktet, være i dampform. Materialet kan om ønsket føres ud gennem en dampseparator 68, som kan være af centrifugaltypen. Dampen føres ud gennem en dampafgang 70 og kan føres til en passende kondensator 71. Kondensatoren 71 kan naturligvis etablere et tilstrækkeligt vakuum, så at dampseparatoren 68 fører dampen ud ved under atmosfæretryk, hvad der bevirker en større omdannelse af den våde damp eller vand til damp. Kondensatoren, der er vist i fig. 1, er af den ba-rometriske kondensatortype, hvori kølevand tilføres gennem en vandindgang 72, og den kondenserede damp og vandet i for-The pump can be controlled to deliver the material at a desired pressure lower than the feed pressure on the inlet side. Pump 65 delivers the material to a suitable conduit 67. Since the temperature of the material is high and the prevailing pressure is substantially reduced, some, if not all, of the water mixed with the product will be in vapor form. If desired, the material may be discharged through a vapor separator 68 which may be of the centrifugal type. The vapor is discharged through a vapor outlet 70 and can be passed to a suitable capacitor 71. Of course, the capacitor 71 can establish a sufficient vacuum so that the vapor separator 68 discharges the vapor at under atmospheric pressure, causing a greater conversion of the wet vapor or water to vapor. . The capacitor shown in FIG. 1 is of the bathometric condenser type in which cooling water is supplied through a water inlet 72 and the condensed vapor and the water in the
