Le feabhsú leanúnach ar chaighdeáin mhaireachtála na ndaoine agus an bhéim mhéadaithe ar chomhluadar peataí, d'fhorbair an tionscal bia peataí domhanda go tapa le blianta beaga anuas. De réir a chéile breathnaítear ar pheataí mar bhaill thábhachtacha den teaghlach, agus tá a sláinte aiste bia agus cáilíocht bia anois mar fhócas d'úinéirí peataí. Chuir sé seo uasghrádú leanúnach ar theicneolaíocht agus ar threalamh próiseála bia peataí chun cinn, ceanglais níos airde maidir le sábháilteacht a chur ar aghaidh, cothú, blas agus cuma bia peataí. Táimid tiomanta do easbhrúiteoirí gairmiúla a sholáthar atá saindeartha le haghaidh táirgeadh bia, le taithí shaibhir i bpróiseáil bia peataí, agus is féidir leo réitigh phróiseála spriocdhírithe a sholáthar do chineálacha éagsúla bia peataí, cabhrú le fiontair éifeachtacht táirgthe a fheabhsú, cáilíocht an táirge a chinntiú, agus buntáiste a fháil sa dian-iomaíocht mhargaidh.
Díreoidh an t-alt seo ar réimse an bhia peataí, mionsaothrú ar theicneolaíocht próiseála bia peataí, prionsabal oibre puffing easbhrúite scriú, na buntáistí a bhaineann lenár easbhrúiteoirí, agus cur i bhfeidhm sonrach trealaimh easbhrúite i dtáirgeadh bia peataí. Forlíonfaidh sé paraiméadair theicniúla mhionsonraithe freisin, sonraí próisis agus pointí pian tionscail chun an t-ábhar a shaibhriú, freastal ar riachtanas líon na bhfocal de 3000-4000 focail, agus tagairt chuimsitheach agus ghairmiúil a sholáthar d'fhiontair agus do chleachtóirí ábhartha sa tionscal bia peataí.
1. Forbhreathnú ar Thionscal an Bhia Peataí agus Tréithe Próiseála
1.1 Staid Reatha agus Treocht Forbartha Thionscal an Bhia Peataí
Le blianta beaga anuas, tá treocht fáis seasta léirithe ag an margadh bia peataí domhanda. Tiomáinte ag fachtóirí cosúil leis an méadú ar líon na peataí, coincheapa tomhaltais peataí a uasghrádú, agus feabhsú na gcónaitheoirí’ cumhacht ceannaigh, an t-éileamh ar ardchaighdeán, tá méadú leanúnach ag teacht ar bhia peataí cothaitheach agus feidhmiúil. De réir staitisticí sonraí ábhartha, sháraigh méid an mhargaidh bia peataí domhanda 100 billiún dollar SAM, agus táthar ag súil go gcoimeádfar ráta fáis de 5%-8% sna blianta atá romhainn. Ina measc, bia peataí tirim puffed, mar an cineál táirge is príomhshrutha, cuntais ar feadh níos mó ná 60% den mhargadh bia peataí iomlán, ina dhiaidh sin táirgí stánaithe fliuch, táirgí leathfhliucha agus sneaiceanna peataí.
Léirítear treocht forbartha an tionscail bia peataí go príomha i dtrí ghné: ar dtús, cothú agus sláinte. Tugann úinéirí peataí aird níos mó agus níos mó ar chomhdhéanamh cothaitheach bia peataí, agus táirgí le nádúrtha, saor ó bhreiseáin, feidhmiúil (mar áilleacht gruaige, cothú boilg, rialú meáchain) tá tréithe níos mó tóir; dara, éagsúlú cineálacha táirgí. Le saibhriú cineálacha peataí agus riachtanais aonair úinéirí peataí, d'fhorbair bia peataí de réir a chéile i dtreo deighilt, cosúil le bia peataí d'aoiseanna éagsúla (coileáin, madraí fásta, madraí scothaosta), pórtha éagsúla, agus coinníollacha fisiceacha éagsúla; sa tríú háit, faisnéis agus éifeachtúlacht na teicneolaíochta próiseála. D'fhonn freastal ar an éileamh táirgeachta ar scála mór agus cobhsaíocht chaighdeán an táirge a chinntiú, Tá fiontair phróiseála bia peataí ag tabhairt isteach trealamh próiseála chun cinn agus córais rialaithe cliste i gcónaí chun éifeachtacht táirgthe a fheabhsú agus costais saothair a laghdú.
I gcoinne an chúlra seo, teicneolaíocht puffing easbhrúite, mar chroí-theicneolaíocht próiseála bia peataí (táirgí puffed tirim go háirithe), tar éis éirí an eochair chun cáilíocht bia peataí agus iomaíochas na bhfiontar a chinneadh. Forbraítear ár n-easbhrúiteoirí gairmiúla do tháirgeadh bia peataí mar fhreagra ar shaintréithe an tionscail agus éileamh an mhargaidh, is féidir leis na pointí pian i bpróiseáil bia peataí a réiteach go héifeachtach agus cabhrú le fiontair táirgeadh ardchaighdeáin agus éifeachtach a bhaint amach.
1.2 Aicmiú Bia Peataí agus a Thréithe Próiseála
Tá éagsúlacht modhanna aicmithe ag bia peataí, is féidir a roinnt i gcineálacha éagsúla de réir na teicneolaíochta próiseála, ábhar uisce, foirm agus úsáid an táirge. Ina measc, de réir na teicneolaíochta próiseála agus ábhar uisce, Tá bia peataí roinnte go príomha i dtáirgí puffed tirim, táirgí leath-fhliuch, táirgí puffed bog, táirgí stánaithe fliuch agus sneaiceanna (nó déileálann). Tá a saintréithe próiseála uathúil féin ag gach cineál bia peataí agus ceanglais maidir le trealamh, mar seo a leanas:
1.2.1 Táirgí Puffed Tirim:
Is é bia peataí tirim puffed an cineál bia peataí is coitianta, le cion uisce de 10%-12%. I measc a phríomh-amhábhar tá béile feola, béile éisc, arbhair (arbhar, cruithneacht, rís), béile pónaire soighe, vitimíní, mianraí agus breiseáin eile. Tá dlúthbhaint ag próiseas próiseála táirgí puffed tirim leis an bpróiseas puffing, a éilíonn úsáid a bhaint as trealamh puffing easbhrúite chun na hamhábhair a phróiseáil i dtáirgí gráinneach le méid aonfhoirmeach, blas briosc agus blastacht maith. Tá seilfré fada ag saintréithe táirgí puffed tirim, stóráil áisiúil agus iompar, agus costas táirgthe íseal, atá oiriúnach le haghaidh táirgeadh ar scála mór agus tóir i measc úinéirí peataí.
Is é príomhriachtanas próiseála táirgí puffed tirim ná go gcaithfear na hamhábhair a puffed go hiomlán, ionas go mbeidh an stáirse sna hamhábhair geilitínithe go hiomlán, rud a chabhródh le díleá agus ionsú peataí. Ag an am céanna, ní mór cruas agus crispness áirithe a bheith ag an táirge chun freastal ar riachtanais coganta peataí agus cabhrú lena gcuid fiacla a ghlanadh. Cuireann sé seo ceanglais ard ar an mbrú easbhrúite, teocht agus luas scriú an easbhrúiteora.
1.2.2 Táirgí Semi-Fliuch:
Tá cion uisce ag bia peataí leathfhliuch 25%-35%, atá idir táirgí tirime agus fliuch. Tá a amhábhair cosúil le táirgí puffed tirim, ach humectants níos mó (mar glycol próipiléine, sorbitol) a chuirtear leis chun bog agus taise an táirge a chothabháil. Tá gá le cóireáil puffála freisin i bpróiseas próiseála táirgí leathfhliucha, ach tá an chéim puffing níos ísle ná mar atá i dtáirgí tirime. Tá tréithe blas bog agus blas bog ag an táirge, atá oiriúnach do pheataí le cumas coganta bocht (cosúil le peataí scothaosta, peataí tinn).
Is é an deacracht a bhaineann le próiseáil táirgí leathfhliucha ná rialú a dhéanamh ar ábhar uisce agus cosc a chur ar mheathlú an táirge. Dá bhrí sin, sa phróiseas próiseála, is gá rialú docht a dhéanamh ar theocht agus ar thaise gach nasc, agus leasaithigh agus taiseoirí cuí a roghnú chun seilfré an táirge a chinntiú.
1.2.3 Táirgí Bog Puffed:
Tá cion uisce ag bia peataí bog puffed 15%-25%, is táirge é idir táirgí tirim puffed agus leath-fhliuch. Tá a phróiseas próiseála cosúil le próiseas táirgí puffed tirim, ach déantar na paraiméadair fhoirmle agus easbhrúite a choigeartú chun an táirge a dhéanamh bog agus leaisteach. Comhcheanglaíonn táirgí bog puffed na buntáistí a bhaineann le táirgí tirim agus leath-fhliuch, le blastacht maith agus díleá éasca, atá oiriúnach do pheataí éagsúla.
1.2.4 Táirgí Stánaithe Fliucha:
Tá ábhar uisce níos mó ná bia peataí stánaithe fliuch 70%, go príomha ag baint úsáide as feoil úr, iasc, glasraí agus amhábhair eile, a phróiseáiltear trí chócaireacht, canning, steiriliú agus próisis eile. Difriúil ó chineálacha eile táirgí, ní gá cóireáil puffála do tháirgí stánaithe fliuch, agus is iad na naisc phróiseála lárnacha atá acu ná cócaireacht agus steiriliú. Tá tréithe cothaithe saibhir ag an táirge, blastacht láidir agus cion ard taise, atá oiriúnach do pheataí nach maith leo uisce óil nó a dteastaíonn cothaithe forlíontach uathu.
Is í an eochair do phróiseáil táirgí stánaithe fliuch ná úire agus sábháilteacht na n-amhábhar a chinntiú, agus an teocht steiriliú agus an t-am a rialú go docht chun baictéir díobhálacha a mharú sa táirge agus an seilfré a leathnú. Ag an am céanna, is gá a áirithiú nach gcailltear comhpháirteanna cothaitheacha an táirge le linn an phróisis chócaireachta agus steiriliú.
1.2.5 Sneaiceanna Peataí (nó Déileálann):
Is bia cúnta do pheataí iad sneaiceanna peataí, a úsáidtear go príomha chun luach saothair a thabhairt do pheataí, feabhas a chur ar a n-giúmar agus cothaithe a fhorlíonadh. Tá na cineálacha sneaiceanna peataí éagsúil, lena n-áirítear sneaiceanna puffed, sneaiceanna feola triomaithe, sneaiceanna jerky, sneaiceanna fiaclóireachta, srl. Ina measc, sneaiceanna puffed cuntas cuid mhór, agus tá a bpróiseas próiseála cosúil le táirgí puffed tirim, ach tá an fhoirmle níos scagtha, agus cuirtear níos mó gníomhairí blaistithe agus breiseáin fheidhmiúla chun freastal ar riachtanais blas agus feidhmiúla peataí.
Tá ceanglais ard ag sneaiceanna peataí maidir le blas, cuma agus feidhmiúlacht. Mar shampla, ní mór cruas agus uigeacht áirithe a bheith ag sneaiceanna fiaclóireachta chun cabhrú le fiacla an pheata a ghlanadh agus calcalas fiacla a chosc; Ní mór do shneaiceanna áilleachta gruaige comhábhair cosúil le lecithin a chur leis chun cabhrú le cáilíocht gruaige an pheata a fheabhsú. Éilíonn sé seo go mbeadh solúbthacht agus inchoigeartaithe maith ag an easbhrúiteoir chun freastal ar riachtanais phróiseála cineálacha éagsúla sneaiceanna.
Is fiú a thabhairt faoi deara ach amháin i gcás táirgí stánaithe, tá dlúthbhaint ag formhór na gcineálacha bia peataí leis an bpróiseas puffing. Ní hamháin go bhfuil puffing mar chuid lárnach de phróiseáil bia peataí, ach freisin tionchar díreach ar cháilíocht, blas, cothaithe agus digestibility bia peataí. Dá bhrí sin, tá sé ríthábhachtach d'fhiontair phróiseála bia peataí an trealamh easbhrúite ceart a roghnú agus máistreacht a dhéanamh ar an teicneolaíocht easbhrúite eolaíoch.
2. Croí-theicneolaíocht Próiseála Bia Peataí: Teicneolaíocht Puffing Easbhrúite
Is príomhtheicneolaíocht phróiseála é teicneolaíocht puffing easbhrúite a chomhtháthaíonn meascadh, ag caoineadh, téamh, easbhrúite agus puffing. Tá sé in úsáid go forleathan i dtáirgeadh bia peataí mar gheall ar a buntáistí a bhaineann le héifeachtacht táirgthe ard, caighdeán maith táirge, inoiriúnaitheacht láidir d'amhábhair agus raon feidhme leathan. I bpróiseáil bia peataí, úsáidtear teicneolaíocht easbhrúite go príomha chun puffing na n-amhábhar a bhaint amach, a dhéanamh ar an stáirse gelatinize, an dínádúr próitéine, agus feabhas a chur ar bhlastacht agus ar dhíleáchas an táirge. Ag an am céanna, is féidir leis baictéir díobhálacha a mharú sna hamhábhair freisin, sábháilteacht bia peataí a chinntiú.
2.1 Saintréithe Amhábhair Bia Peataí agus Ceanglais maidir le Trealamh Easbhrúite
Is táirgí feola iad amhábhair bia peataí den chuid is mó (ar nós béile feola, béile éisc, feoil úr), arbhair, béile pónaire soighe, vitimíní, mianraí agus breiseáin eile. Ina measc, is ionann táirgí feola agus cuid mhór, rud a fhágann go bhfuil slaodacht láidir ag an táirge. Cuireann an tréith seo ceanglais speisialta ar aghaidh maidir le trealamh easbhrúite:
Níl easbhrúiteoirí aon-scriú oiriúnach do tháirgeadh eacnamaíoch bia peataí. Toisc go bhfuil raon lomadh caol ag an easbhrúiteoir aon-scriú, cumas caidéalaithe bocht agus gan aon éifeacht féin-ghlanadh. Agus ábhair slaodach cosúil le táirgí feola á bpróiseáil, tá sé éasca a bheith ina chúis le carnadh ábhar, bac agus meascadh míchothrom sa bairille easbhrúiteora, rud a chuireann isteach ní hamháin ar éifeachtacht táirgthe, ach freisin mar thoradh ar chaighdeán táirge éagobhsaí. Ina theannta sin, tá tomhaltas ardfhuinnimh ag an easbhrúiteoir aon-scriú nuair a bhíonn amhábhair ard-saill agus ard-próitéine á phróiseáil, rud a mhéadaíonn costas táirgthe na bhfiontar.
Easbhrúiteoirí dhá-scriú, ar an láimh eile, buntáistí soiléire i dtáirgeadh bia peataí. Tá raon lomadh níos leithne acu, éifeacht caidéalaithe níos éifeachtaí agus éifeacht féin-ghlanadh, ar féidir leo na fadhbanna a bhaineann le slaodacht agus carnadh ábhar a réiteach go héifeachtach. Is féidir leis an easbhrúiteoir cúpla-scriú an meascadh aonfhoirmeach a bhaint amach, kneading agus easbhrúite ábhar, fiú nuair a dhéantar amhábhair a phróiseáil a bhfuil cion ard saille agus feola úra iontu, féadfaidh sé freisin táirgeadh cobhsaí agus cáilíocht táirgí comhsheasmhach a chinntiú. Dá bhrí sin, i dtáirgeadh iarbhír bia peataí, tá easbhrúiteoirí cúpla-scriú anois mar phríomh-mhodh puffála bia peataí, agus úsáidtear iad go forleathan i dtáirgeadh táirgí puffed tirim, táirgí leath-fhliuch, táirgí puffed bog agus sneaiceanna peataí.
2.2 Prionsabal Oibre Puffing Easbhrúite Scriú
The screw extrusion puffing process of pet food is a complex physical and chemical process, which involves the interaction of multiple factors such as temperature, brú, shear force and time. The specific working principle is as follows:
Ar dtús, raw material pretreatment. The powdery raw materials containing a certain amount of starch (níos mó ná 20%) are mixed uniformly according to the formula, and then sent to the tempering device for tempering treatment. The purpose of tempering is to adjust the moisture content and temperature of the materials, so that the materials can reach the ideal state before entering the extruder. Go ginearálta, the moisture content of the materials after tempering is controlled at 10%～27%, and the temperature is raised to 70～98℃. During the tempering process, the materials absorb water evenly, rud a chabhródh le geilitíniú stáirse ina dhiaidh sin agus dínádúrú próitéine, agus is féidir freisin caitheamh an scriú easbhrúite agus bairille a laghdú.
Dara, easbhrúite agus téamh. Téann na hábhair tempered isteach sa chuas easbhrúite scriú tríd an bhfeiste beathaithe. Tá cuas easbhrúite an scriú comhdhéanta de scriú agus bairille, agus laghdaítear méid na cuas easbhrúite de réir a chéile feadh an treo aise. Nuair a rothlaíonn an scriú, cuireann sé na hábhair ar aghaidh go leanúnach, agus déantar na hábhair a chomhbhrú de réir a chéile faoi ghníomhaíocht an scriú agus an bharaille, agus méadaíonn an brú sa chuas easbhrúite de réir a chéile. An cóimheas comhbhrú (an cóimheas idir toirt an ábhair ag an deireadh beathú agus an toirt ag an deireadh easbhrúite) in ann 410 a bhaint amach, a athraíonn de réir an chineáil bia peataí agus foirmle na n-amhábhar.
Le linn an phróisis a bheith á bhrú agus easbhrúite ag an scriú, tá na hábhair faoi réir fórsa lomadh láidir agus fórsa cuimilte. Gineann an ghluaiseacht choibhneasta idir an scriú agus an bairille an fórsa lomadh, chomh maith le idir na heitiltí scriú. Is féidir leis cáithníní na n-ábhar a bhriseadh, déan na hamhábhair agus na breiseáin a mheascadh go haonfhoirmeach, agus geilitíniú stáirse agus dínádúrú próitéine a chur chun cinn. Gintear an fórsa frithchuimilte idir na hábhair agus balla istigh an bharaille, chomh maith le idir na cáithníní ábhar, is féidir a ghiniúint go leor teasa, rud a chabhródh le téamh na n-ábhar. Ina theannta sin, de réir na riachtanas próiseála, is féidir le gaile sreabhadh tríd an seaicéad bairille chun na hábhair idir na ballaí a théamh, ionas go mbeidh na hábhair sa chuas easbhrúite i stát ardteochta agus ardbhrú. Go ginearálta rialaítear an teocht sa chuas easbhrúite ag 120 ~ 180 ℃, agus tá an brú á rialú ag 2～10MPa.
Tríú, geilitíniú stáirse agus dínádúrú próitéine. Faoi ghníomh teocht ard, brú ard agus fórsa lomadh, súnn an stáirse sna hábhair uisce agus leathnaíonn sé, tá an struchtúr criostail scriosta, agus déantar é a thiontú ina stát éagruthach, ar a dtugtar geilitíniú stáirse. Is féidir le geilitíniú stáirse feabhas a chur ar dhíleáchas bia peataí, toisc go bhfuil an stáirse geilitínithe níos éasca a dhianscaoileadh ag einsímí díleácha peataí. Ag an am céanna, is féidir leis an stáirse geilitínithe freisin slaodacht agus fórsa ceangailteach na n-ábhar a fheabhsú, rud a fhágann go bhfuil cruth agus uigeacht mhaith ar na táirgí easbhrúite.
Chomh maith le geilitíniú stáirse, déanfar an próitéin sna hábhair a dhínádúrú freisin faoi ghníomh teocht ard agus ardbhrú. Tagraíonn dínádúrú próitéin d'athrú ar struchtúr spásúil móilíní próitéine gan an struchtúr bunscoile a athrú, is féidir a fheabhsú tuaslagthacht agus digestibility próitéine, agus a dhéanamh ar an mbia peataí a bhfuil blas níos fearr. Ag an am céanna, is féidir leis an próitéin dínádúraithe struchtúr líonra a fhoirmiú freisin, is féidir a wrap an stáirse agus comhpháirteanna eile, ag cuidiú le cruth an táirge puffed a choinneáil.
Ceathrú, puffing agus múnlú. Nuair a bhíonn na hábhair sa stát ardteochta agus ardbhrú á bhrú go dtí an ceann bás ag an scriú agus easbhrúite as an bpoll bás ag luas ard, the temperature and pressure of the materials drop sharply because they suddenly leave the extrusion cavity and enter the normal atmospheric environment. Under the combined action of pressure difference and temperature difference, the water in the materials evaporates rapidly, the volume of the materials expands rapidly (the expansion rate can reach 2～8 times), and the materials are dehydrated and solidified quickly to form a porous, crisp or soft puffed product.
After extrusion from the die hole, the puffed materials are cut into short particles of uniform length by the cutting device (rotary knife) installed at the die head. The length of the particles can be adjusted by changing the speed of the rotary knife to meet the requirements of different types of pet food. Mar shampla, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Cúigiú, post-processing. The extruded puffed particles need to go through post-processing links such as drying, fuaraithe, seasoning and packaging to become the final pet food products. Drying is to reduce the water content of the particles to the standard range (10%-12% for dry products), so as to extend the shelf life of the product. Cooling is to reduce the temperature of the dried particles to room temperature, prevent the product from caking and deteriorating. Seasoning is to spray flavoring agents, attractants and other additives on the surface of the particles to improve the palatability of the product. Is éard atá i bpacáistiú na cáithníní seasoned a phacáil isteach i málaí nó cannaí chun sláinteachas agus sábháilteacht an táirge a chinntiú agus chun stóráil agus iompar a éascú.
2.3 Príomhfhachtóirí a Bhfuil Tionchar acu ar Éifeacht Puffing Easbhrúite Scriú
Bíonn tionchar díreach ag éifeacht puffing easbhrúite scriú ar chaighdeán bia peataí. Tá go leor fachtóirí ann a dhéanann difear don éifeacht puffing, go príomha lena n-áirítear saintréithe amhábhar, paraiméadair faghartha, paraiméadair easbhrúite agus struchtúr ceann bás. Má dhéantar na príomhfhachtóirí seo a mháistir agus coigeartuithe eolaíocha a dhéanamh, is féidir cobhsaíocht an éifeacht puffing agus comhsheasmhacht chaighdeán an táirge a chinntiú.
2.3.1 Tréithe Amhábhar:
An cineál, méid na gcáithníní, tá tionchar mór ag cion taise agus comhdhéanamh cothaitheach na n-amhábhar ar an éifeacht puffing. Mar shampla, the starch content of raw materials directly affects the expansion rate of the product. The higher the starch content (within a certain range), the better the puffing effect, and the larger the expansion rate of the product. The particle size of raw materials should be uniform, generally 80-100 mogalra. If the particle size is too large, the materials are not easy to be mixed uniformly and plasticized fully, which affects the puffing effect; if the particle size is too small, it is easy to cause material blockage and increase energy consumption. The moisture content of raw materials before tempering should be controlled at 8%-12%. If the moisture content is too high, the materials are easy to stick to the screw and barrel, affecting the extrusion and puffing; if the moisture content is too low, the shear force and friction force between the materials are insufficient, and the starch gelatinization is incomplete, resulting in poor puffing effect.
2.3.2 Tempering Parameters:
Tempering parameters mainly include tempering temperature, tempering time and moisture content after tempering. The tempering temperature is generally 70～98℃. If the tempering temperature is too low, the materials cannot absorb water evenly, and the starch gelatinization is insufficient; if the tempering temperature is too high, the materials may be caked in advance, affecting the subsequent extrusion. The tempering time is generally 2-5 nóiméad, which should be adjusted according to the type of raw materials and the moisture content. The moisture content after tempering is 10%～27%, which varies according to the type of pet food. Mar shampla, the moisture content of dry puffed products after tempering is generally 15%-20%, while that of semi-wet products is 22%-27%.
2.3.3 Extrusion Parameters:
Extrusion parameters are the most important factors affecting the puffing effect, mainly including screw speed, extrusion temperature and extrusion pressure. Screw speed generally ranges from 100 chuig 600 rpm. The higher the screw speed, the greater the shear force and friction force received by the materials, the higher the extrusion temperature and pressure, and the better the puffing effect. Mar sin féin, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete starch gelatinization and uneven mixing; if the screw speed is too low, the shear force and friction force are insufficient, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: alt bheathú, melting section and homogenizing section. The temperature of the feeding section is lower (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; the temperature of the melting section is medium (120～150℃), which is mainly to promote the melting and plasticization of the materials; the temperature of the homogenizing section is higher (150～180℃), which is mainly to ensure the uniform mixing and full gelatinization of the materials.
Extrusion pressure is generally 2～10MPa. The pressure in the extrusion cavity is mainly determined by the compression ratio of the screw, the die hole size and the screw speed. The higher the extrusion pressure, the better the puffing effect, but if the pressure is too high, it will increase the energy consumption and wear of the equipment; if the pressure is too low, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 Die Head Structure:
The die head structure mainly includes the number, shape and size of die holes. The shape of the die hole determines the cross-sectional shape of the puffed product, such as circular, square, triangular and other shapes. The size of the die hole determines the initial diameter of the product. The smaller the die hole size, the greater the extrusion pressure, and the better the puffing effect, but the production capacity will be reduced. The number of die holes affects the production capacity. The more the number of die holes, the higher the production capacity, but it is necessary to ensure that the pressure distribution is uniform, so as to avoid uneven puffing of the product.
3. Our Extruders: Advantages and Product Series for Pet Food Production
We have long been engaged in the research, development and production of food-grade extruders, and have developed a series of twin-screw extruders specially suitable for pet food production according to the characteristics of pet food processing and the needs of enterprises. Our extruders have the advantages of low operating cost, wide application range, advanced technology and reliable process control, which can meet the processing needs of various types of pet food and help enterprises improve production efficiency and product quality.
3.1 Main Advantages of Our Extruders
3.1.1 Low Lifetime Operating Cost:
We focus on the durability and economy of the equipment, and adopt high-quality materials and advanced manufacturing technology to ensure that the extruder has a long service life and low operating cost.
