Isla markaana, waa lagama maarmaan in la hubiyo in qaybaha nafaqada ee alaabta aan la lumin inta lagu jiro habka karinta iyo jeermiska.
1.2.5 Cuntooyinka Xayawaanka (ama daaweeya):
Cuntooyinka fudud ee xayawaanku waa cunto kaabayaal ah oo loogu talagalay xayawaanka rabaayada ah, inta badan loo isticmaalo in lagu abaalmariyo xayawaanka rabaayada ah, wanaaji niyadooda oo kaabi nafaqada. Noocyada cuntooyinka fudud ee xayawaanku waa kala duwan yihiin, oo ay ku jiraan cunto fudud oo bararsan, cunto fudud oo hilib la qalajiyey, cunto fudud oo qalafsan, cunto fudud ilkeed, iwm. Waxaa ka mid ah, Cuntooyinka fudfudud waxay ku xisaabtamayaan qayb weyn, nidaamkooduna wuxuu la mid yahay badeecooyinka qallalan ee bararsan, laakiin qaacidada ayaa ka sii sifaysan, iyo walxo dhadhamin oo badan iyo wax-qabadyo lagu daro ayaa lagu daraa si loo daboolo dhadhanka iyo baahiyaha shaqo ee xayawaanka rabaayada ah.
Cuntooyinka fudud ee xayawaanku waxay leeyihiin shuruudo sare oo dhadhanka, muuqaalka iyo shaqeynta. Tusaale ahaan, Cuntooyinka fudud ee ilkuhu waxay u baahan yihiin inay lahaadaan qallafsanaan gaar ah iyo qaabdhismeed si ay uga caawiyaan nadiifinta ilkaha xayawaanka iyo ka hortagga calculus ilkaha; Cuntooyinka fudud ee timaha qurxinaya waxay u baahan yihiin inay ku daraan maaddooyinka sida lecithin si ay u caawiyaan hagaajinta tayada timaha xayawaanka rabaayada ah. Tani waxay u baahan tahay daba-qaadaha si uu u yeesho dabacsanaan iyo hagaajin wanaagsan si uu u daboolo baahiyaha habaynta ee noocyada kala duwan ee cunto fudud.
Waxaa xusid mudan marka laga reebo alaabta qasacadaysan, Inta badan noocyada cuntada xayawaanku waxay si dhow ula xiriiraan habka bararka.

Waxaa si weyn loogu isticmaalay wax soo saarka cuntada xayawaanka sababtoo ah faa'iidooyinka waxtarka sare ee wax soo saarka, tayada alaabta wanaagsan, laqabsiga xooggan ee alaabta ceeriin iyo kala duwanaanta codsiga ballaaran. In habaynta cuntada xayawaanka, Tignoolajiyada extrusion inta badan waxaa loo isticmaalaa si loo xaqiijiyo buufida alaabta ceeriin, ka dhig istaarijka gelatinize, denateurka borotiinka, iyo hagaajinta dhadhanka iyo dheefshiidka alaabta. Isla markaana, Waxa kale oo ay dili kartaa bakteeriyada waxyeelada leh ee ku jirta alaabta ceeriin, hubi badbaadada cuntada xayawaanka.
2.1 Astaamaha Alaabta Ceyriin ee Cunnada Xayawaanka iyo Shuruudaha Qalabka Soo saarista
Maaddooyinka cayriin ee cuntada xayawaanku waa inta badan hilibka (sida cuntada hilibka, cuntada kalluunka, hilib cusub), badarka, cunto soybean ah, fitamiino, macdanta iyo waxyaabaha kale ee lagu daro. Waxaa ka mid ah, wax soo saarka hilibka ayaa lagu xisaabiyaa qayb weyn, samaynta alaabtu waxay leedahay viscosity xooggan. Dabeecaddani waxay soo bandhigaysaa shuruudo gaar ah oo loogu talagalay qalabka extrusion:
Extruders-ka-xiran kuma haboona wax soo saarka dhaqaalaha ee cuntada xayawaanka. Sababtoo ah bakhtiiyaha hal-boolaha ah wuxuu leeyahay kala duwanaansho cidhiidhi ah, awoodda bamgareynta liidata iyo wax saameyn ah oo is-nadiifin ah ma leh. Marka la warshadeynayo walxaha viscous sida hilibka, Way fududahay in la keeno alaab urursi, xannibaadda iyo isku dhafka aan sinnayn ee foosto extruder, taas oo aan saameyn ku yeelan wax soo saarka oo kaliya, laakiin sidoo kale waxay keenaysaa tayada alaabta oo aan degganayn. Intaa waxaa dheer, extruder-ka-bilaha ah ayaa leh isticmaalka tamar sare marka la farsameynayo alaabta ceeriin ee dufanka badan iyo borotiinka sare, taasoo kordhisa qiimaha wax soo saarka shirkadaha.
Twin-screw extruders, dhanka kale, waxay leeyihiin faa'iidooyin muuqda oo ku saabsan wax soo saarka cuntada xayawaanka. Waxay leeyihiin kala duwanaansho xiiran oo ballaaran, Saamaynta bamgareynta waxtarka badan iyo saamaynta is-nadiifinta, kaas oo si wax ku ool ah u xallin kara dhibaatooyinka maaddada viscosity iyo ururinta. Extruder-ga mataanaha ah ayaa ogaan kara isku darka labbiska, cajiin iyo ka saaridda alaabta, xitaa marka lagu farsameeyo alaabta ceeriin ee leh dufan badan iyo hilib cusub, waxay sidoo kale xaqiijin kartaa wax soo saarka xasilloon iyo tayada badeecada joogtada ah. Sidaa darteed, in wax soo saarka dhabta ah ee cuntada xayawaanka, Twin-screw extruders ayaa noqday habka ugu muhiimsan ee cunnada xayawaanka lagu dhaqo, waxaana si weyn loogu isticmaalaa soo saarista alaabada qallalan ee qallalan, wax soo saarka semi-qoyan, alaabo jilicsan iyo cunto fudud oo xayawaan ah.
2.2 Mabaadi'da Shaqaynta ee Screw Extrusion Puffing
Geedi socodka bararka daba-dheeraada ee cunnada xayawaanku waa nidaam jidheed iyo kiimiko oo adag, kaas oo ku lug leh isdhexgalka arrimo badan sida heerkulka, cadaadis, xoog xiirid iyo waqti. Mabda'a shaqada gaarka ah waa sida soo socota:
Marka hore, pretreatment alaabta ceeriin. Walxaha ceeriin budada ah oo ay ku jiraan xaddi istaarij ah (ka badan 20%) waa la isku qasan si isku mid ah iyadoo loo eegayo qaacidada, ka dibna loo diro aaladda dab-damiska si loogu daweeyo xanaaqa. Ujeedada xanaaqa waa in la hagaajiyo qoyaanka qoyaanka iyo heerkulka alaabta, si ay alaabtu u gaarto heerka ugu habboon ka hor inta aysan gelin extruder-ka. Guud ahaan, Maaddada qoyaanka ee alaabta ka dib heerkulka waxaa lagu xakameynayaa 10% ~ 27%, Heerkulkana waxa la gaadhsiiyay 70°98℃. Inta lagu jiro habka xanaaqa, Maaddooyinka ayaa si siman u nuuga biyaha, taas oo u sahlaysa gelatinization-ka xiga ee istaarijka iyo denaturation ee borotiinka, iyo sidoo kale hoos u dhigi kara xirashada furaha iyo foosto extruder.
Labaad, extrusion iyo kululaynta. Walxaha xamaasadda leh waxay ka soo galaan daloolka furka furka iyagoo sii maraya qalabka quudinta. Godka fur-fududku wuxuu ka kooban yahay fur iyo foosto, iyo mugga daloolka extrusion ayaa si tartiib tartiib ah hoos ugu dhacaya jihada dhidibka. Marka furku wareego, waxay u riixdaa alaabta si joogto ah, iyo alaabtu si tartiib tartiib ah ayaa loo cadaadiyaa iyadoo la raacayo ficilka furka iyo foosto, iyo cadaadiska godka extrusion si tartiib tartiib ah u kordho. Saamiga cadaadisku (saamiga mugga alaabta ee dhamaadka quudinta ilaa mugga dhamaadka extrusion) waxay gaari kartaa 4-10, taas oo ku kala duwan hadba nooca cuntada xayawaanka iyo qaabka alaabta ceeriin.
Inta lagu guda jiro habka lagu riixayo iyo ka saarista biraha, Qalabka waxaa lagu sakhraamo xoog xiiran oo xoog leh iyo xoog is jiid jiid. Xoogga xiiridda waxaa dhaliya dhaqdhaqaaqa qaraabada ah ee u dhexeeya furka iyo foosto, iyo sidoo kale inta u dhaxaysa duullimaadyada wareegyada. Waxay jebin kartaa qaybaha alaabta, samee alaabta ceeriin iyo waxyaabaha lagu daro si isku mid ah, iyo kor u qaadida gelatinization ee istaarijka iyo denaturation ee borotiinka. Xoogga is jiid jiidka ayaa ka dhex abuurma walxaha iyo gidaarka gudaha ee foosto, iyo sidoo kale inta u dhaxaysa qaybaha walxaha, kaas oo dhalin kara kulayl badan, kaas oo ku haboon kuleylinta alaabta. Intaa waxaa dheer, iyadoo loo eegayo baahida farsamaynta, uumi wuxuu ku dhex qulquli karaa jaakada foosto si uu u kululeeyo walxaha gidaarada dhexdooda, si alaabta ku jirta godka extrusion ay ku jiraan heerkul sare iyo heerkul sare. Heerkulka godka extrusion guud ahaan waxaa lagu xakameynayaa 120 180 ℃, waxaana lagu xakameynayaa cadaadiska 2～10MPa.
Saddexaad, Gelatin istaarijka iyo diidmada borotiinka. Hoosta ficilka heerkulka sare, cadaadiska sare iyo xoogga dhogorta, istaarijka ku jira maaddooyinka ayaa nuuga biyaha oo balaadha, qaab dhismeedka crystal waa la dumiyey, waxaana loo beddelaa xaalad aan caadi ahayn, kaas oo loo yaqaan istaarijka gelatinization. Gelatin-is-taagga istaarijku waxay hagaajin kartaa dheefshiidka cuntada xayawaanka rabaayada ah, sababtoo ah istaarijka jelatinized ayaa fududaanaya in ay burburiyaan enzymes dheefshiidka ee xayawaanka rabaayada ah. Isla markaana, the gelatinized starch can also improve the viscosity and binding force of the materials, making the extruded products have good shape and texture.
In addition to starch gelatinization, the protein in the materials will also undergo denaturation under the action of high temperature and high pressure. Protein denaturation refers to the change of the spatial structure of protein molecules without changing the primary structure, which can improve the solubility and digestibility of protein, and make the pet food have better palatability. Isla markaana, the denatured protein can also form a network structure, which can wrap the starch and other components, helping to maintain the shape of the puffed product.
Afaraad, puffing and shaping. When the materials in the high-temperature and high-pressure state are pushed to the die head by the screw and extruded from the die hole at a high speed, 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, biyaha ku jira maaddooyinka ayaa si degdeg ah uumi baxa, mugga alaabta ayaa si degdeg ah u fidiya (heerka balaadhinta wuxuu gaari karaa 2-8 jeer), and the materials are dehydrated and solidified quickly to form a porous, badeeco qallafsan ama jilicsan oo bararsan.
Ka dib markii laga saaro godka dhinta, the puffed materials are cut into short particles of uniform length by the cutting device (mindi wareeg ah) lagu rakibay madaxa dhinta. Dhererka qaybaha waxaa lagu hagaajin karaa iyadoo la beddelayo xawaaraha mindida wareega si loo buuxiyo shuruudaha noocyada kala duwan ee cuntada xayawaanka.. Tusaale ahaan, Qaybaha cunnada eygaaga ayaa ka yar oo gaaban, halka qaybaha cuntada eeyga qaangaarka ah ay ka weyn yihiin oo dheer yihiin.
Shanaad, ka dib habaynta. Walxaha bararsan waxay u baahan yihiin inay dhex maraan isku-xidhka habaynta ka dib sida qalajinta, qaboojin, xawaash iyo baakad si ay u noqdaan cuntooyinka ugu dambeeya ee xayawaanka. Qalajintu waa in la yareeyo biyaha ku jira qaybaha ilaa heerka caadiga ah (10%-12% alaabta qalalan), si loo kordhiyo cimriga alaabta. Qaboojintu waa in la dhimo heerkulka qaybaha la qalajiyey heerkulka qolka, ka ilaali badeecada in ay dhalaaliso oo ay xumaato. Xawaashku waa in lagu buufiyo walxaha dhadhanka, attractants and other additives on the surface of the particles to improve the palatability of the product. Packaging is to pack the seasoned particles into bags or cans to ensure the hygiene and safety of the product and facilitate storage and transportation.
2.3 Key Factors Affecting Screw Extrusion Puffing Effect
The effect of screw extrusion puffing directly affects the quality of pet food. There are many factors affecting the puffing effect, inta badan ay ku jiraan sifooyinka alaabta ceeriin, tempering parameters, xuduudaha extrusion iyo dhinta qaab-dhismeedka madaxa. Mastering these key factors and making scientific adjustments can ensure the stability of the puffing effect and the consistency of product quality.
2.3.1 Astaamaha Qalabka Ceyriinka:
Nooca, cabbirka walxaha, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Tusaale ahaan, the starch content of raw materials directly affects the expansion rate of the product. Inta badan waxa ku jira istaarijku (ilaa xad go'an), sida ugu wanagsan ee ay u yeelan karto cuncun, iyo korodhka heerka ballaarinta alaabta. The particle size of raw materials should be uniform, guud ahaan 80-100 mesh. Haddii cabbirka qaybuhu aad u weyn yahay, the materials are not easy to be mixed uniformly and plasticized fully, kaas oo saameeya saamaynta bararka; haddii xajmigu aad u yar yahay, 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%. Haddii qoyaanku aad u sarreeyo, the materials are easy to stick to the screw and barrel, saameyn ku yeelata bararka iyo bararka; haddii qoyaanku aad u yar yahay, the shear force and friction force between the materials are insufficient, iyo gelatinization istaarijku waa mid aan dhamaystirnayn, 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 daqiiqado, 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. Tusaale ahaan, 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 Qiyaasaha Extrusion:
Extrusion parameters are the most important factors affecting the puffing effect, inta badan ay ku jiraan xawaaraha isbiirsaday, heerkulka extrusion iyo cadaadiska extrusion. Screw speed generally ranges from 100 ku 600 rpm. Xawaaraha isbiirtadu wuu sarreeyaa, hadba sida ay u weynaato xoogga xiiraya iyo xoogga is jiid-jiidka ee ay heleen agabku, the higher the extrusion temperature and pressure, and the better the puffing effect. Si kastaba ha ahaatee, haddii xawaaruhu aad u sarreeyo, wakhtiga ay ku nool yihiin alaabta ku jirta godka extrusion aad buu u gaaban yahay, resulting in incomplete starch gelatinization and uneven mixing; haddii xawaaruhu aad u yar yahay, xoog-xiirid iyo xoog is jiid-jiidku kuma filna, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: qaybta quudinta, melting section and homogenizing section. Heerkulka qaybta quudinta ayaa hooseeya (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; heerkulka qaybta dhalaalidu waa dhexdhexaad (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.
Cadaadiska saarista guud ahaan waa 2 ~ 10MPa. Cadaadiska ku jira godka extrusion waxaa inta badan lagu go'aamiyaa saamiga isku-buufinta ee furaha, cabbirka godka dhinta iyo xawaarihiisa isku dhufashada. Cadaadiska extrusionka ayaa sarreeya, sida ugu wanagsan ee ay u yeelan karto cuncun, laakiin haddii cadaadisku aad u sarreeyo, waxay kordhin doontaa isticmaalka tamarta iyo xirashada qalabka; haddii cadaadisku aad u hooseeyo, Saamaynta fuudka ayaa liidata, alaabtuna waa dabacsan oo fudud in la jebiyo.
2.3.4 Dhimashada Madaxa Qaab dhismeedka:
The die head structure mainly includes the number, qaabka iyo cabbirka godadka dhinta. The shape of the die hole determines the cross-sectional shape of the puffed product, sida wareegto, afar geesle, saddex xagal iyo qaabab kale. 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.
