1.2 Klasifikasi Panganan Pet lan Karakteristik Pangolahan
Panganan kewan duwe macem-macem cara klasifikasi, sing bisa dipérang dadi macem-macem jinis miturut teknologi pangolahan, isi banyu, wangun produk lan nggunakake. Antarane wong-wong mau, miturut teknologi pangolahan lan isi banyu, panganan pet utamané dipérang dadi produk puffed garing, produk semi-wet, produk puffed alus, produk kaleng udan lan cemilan (utawa nambani). Saben jinis panganan pet duwe karakteristik pangolahan lan syarat khusus kanggo peralatan, kaya ing ngisor iki:
1.2.1 Produk Kering Kering:
Panganan pet sing garing yaiku jinis panganan pet sing paling umum, karo isi banyu saka 10%-12%. Bahan baku utama kalebu panganan daging, panganan iwak, sereal (jagung, gandum, beras), dhaharan kedhele, vitamins, mineral lan aditif liyane. Proses pangolahan produk puffing garing ana hubungane karo proses puffing, sing mbutuhake panggunaan peralatan puffing extrusion kanggo ngolah bahan mentah dadi produk granular kanthi ukuran seragam, rasa asri lan palatability apik. Karakteristik produk puffed garing yaiku umur beting sing dawa, panyimpenan trep lan transportasi, lan biaya produksi sing murah, sing cocok kanggo produksi skala gedhe lan populer ing kalangan pamilik pet.
Syarat pangolahan utama produk puffed garing yaiku bahan mentah kudu diisi kanthi lengkap, supaya pati ing bahan mentahan wis kebak gelatinized, sing kondusif kanggo pencernaan lan panyerepan saka pets. Ing wektu sing padha, prodhuk kasebut kudu nduweni kekerasan lan crispness tartamtu kanggo nyukupi kabutuhan ngunyah pets lan mbantu ngresiki untune. Iki ndadekake syarat dhuwur ing tekanan ekstrusi, suhu lan kacepetan meneng saka extruder.
1.2.2 Produk Semi Basah:
Panganan pet semi-udan nduweni isi banyu 25%-35%, kang antarane produk garing lan udan. Bahan bakune padha karo produk kembung garing, nanging luwih humektan (kayata propylene glycol, sorbitol) ditambahake kanggo njaga kelembutan lan kelembapan produk. Proses pangolahan produk semi-udan uga mbutuhake perawatan puffing, nanging tingkat puffing luwih murah tinimbang produk garing. Produk kasebut nduweni ciri rasa alus lan rasa enak, sing cocok kanggo pets karo kemampuan chewing miskin (kayata pets tuwa, pets lara).
Kesulitan pangolahan produk semi-udan dumunung ing kontrol isi banyu lan nyegah rusak produk. Mulane, ing proses pangolahan, iku perlu kanggo strictly ngontrol suhu lan asor saben link, lan pilih preservatives cocok lan humectants kanggo mesthekake urip beting prodhuk.
1.2.3 Produk Soft Puff:
Panganan pet puffed alus nduweni isi banyu 15%-25%, yaiku produk antarane produk puffed garing lan semi-udan. Proses pangolahan padha karo produk puff garing, nanging rumus lan paramèter extrusion diatur kanggo nggawe produk alus lan elastis. Produk puffed alus nggabungake kaluwihan produk garing lan semi-udan, karo palatability apik lan gampang dicerna, sing cocok kanggo macem-macem pets.
1.2.4 Produk Kaleng Basah:
Wet canned pet food has a water content of more than 70%, mainly using fresh meat, fish, vegetables and other raw materials, which are processed by cooking, canning, sterilization and other processes. Different from other types of products, wet canned products do not need puffing treatment, and their core processing links are cooking and sterilization. The product has the characteristics of rich nutrition, strong palatability and high moisture content, which is suitable for pets who do not like drinking water or need supplementary nutrition.
The key to the processing of wet canned products is to ensure the freshness and safety of raw materials, and strictly control the sterilization temperature and time to kill harmful bacteria in the product and extend the shelf life. Ing wektu sing padha, perlu kanggo mesthekake yen komponen nutrisi produk ora ilang sajrone proses masak lan sterilisasi.
1.2.5 Cemilan Pet (utawa Ngruwat):
Cemilan kewan minangka panganan tambahan kanggo kewan, utamané digunakake kanggo ganjaran pets, nambah swasana ati lan nutrisi tambahan. Jinis cemilan kewan macem-macem, kalebu jajanan kembung, jajanan daging garing, cemilan dendeng, cemilan dental, lsp. Antarane wong-wong mau, cemilan puffed akun kanggo proporsi gedhe, lan proses pangolahan padha karo produk puffed garing, nanging rumus luwih olahan, lan luwih akeh agen perasa lan aditif fungsional sing ditambahake kanggo nyukupi rasa lan kabutuhan fungsional pets.
Cemilan pet duwe syarat dhuwur kanggo rasa, tampilan lan fungsi. Contone, cemilan dental kudu duwe kekerasan lan tekstur tartamtu kanggo ngresiki untu kewan lan nyegah kalkulus dental; hair-beautifying snacks need to add ingredients such as lecithin to help improve the pet’s hair quality. This requires the extruder to have good flexibility and adjustability to meet the processing needs of different types of snacks.
It is worth noting that except for canned products, most types of pet food are closely related to the puffing process. Puffing is not only the core part of pet food processing, but also directly affects the quality, taste, nutrition and digestibility of pet food. Mulane, choosing the right extrusion equipment and mastering the scientific extrusion technology are crucial for pet food processing enterprises.
2. Core Technology of Pet Food Processing: Extrusion Puffing Technology
Extrusion puffing technology is a key processing technology integrating mixing, kneading, dadi panas, extrusion and puffing. It has been widely used in the production of pet food due to its advantages of high production efficiency, kualitas produk apik, daya adaptasi kuwat kanggo bahan mentahan lan sawetara aplikasi sudhut. In the processing of pet food, extrusion technology is mainly used to realize the puffing of raw materials, make the starch gelatinize, the protein denature, and improve the palatability and digestibility of the product. Ing wektu sing padha, it can also kill harmful bacteria in the raw materials, ensure the safety of pet food.
2.1 Characteristics of Pet Food Raw Materials and Requirements for Extrusion Equipment
The raw materials of pet food are mainly meat products (such as meat meal, panganan iwak, daging seger), sereal, dhaharan kedhele, vitamins, mineral lan aditif liyane. Antarane wong-wong mau, meat products account for a large proportion, making the product have strong viscosity. This characteristic puts forward special requirements for extrusion equipment:
Extruders sekrup tunggal ora cocok kanggo produksi ekonomi panganan pet. Amarga extruder siji-screw duwe sawetara geser sing sempit, kapasitas pumping miskin lan ora ana efek reresik dhewe. Nalika ngolah bahan kenthel kayata produk daging, iku gampang kanggo nimbulaké akumulasi materi, blockage lan campuran ora rata ing tong minyak extruder, sing ora mung mengaruhi efisiensi produksi, nanging uga nyebabake kualitas produk sing ora stabil. Kajaba iku, extruder siji-meneng nduweni konsumsi energi dhuwur nalika Processing dhuwur-lemak lan dhuwur-protein bahan mentahan, sing nambah biaya produksi perusahaan.
Twin-meneng extruders, ing sisih liyane, duwe kaluwihan sing jelas ing produksi panganan pet. Dheweke duwe jangkoan geser sing luwih akeh, efek pumping luwih efektif lan efek self-cleaning, sing bisa ngatasi masalah viskositas lan akumulasi materi kanthi efektif. Extruder sekrup kembar bisa nyadari pencampuran seragam, kneading lan extrusion saka bahan, malah nalika ngolah bahan mentah kanthi kandungan lemak dhuwur lan daging seger, uga bisa njamin produksi stabil lan kualitas produk konsisten. Mulane, ing produksi nyata panganan pet, extruders kembar-meneng wis dadi sarana utama puffing pangan pet, lan digunakake digunakake ing produksi produk puffed garing, produk semi-wet, produk puffed alus lan cemilan pet.
2.2 Prinsip Kerja Screw Extrusion Puffing
Proses puffing ekstrusi sekrup panganan pet minangka proses fisik lan kimia sing kompleks, sing melu interaksi sawetara faktor kayata suhu, tekanan, gaya geser lan wektu. Prinsip kerja tartamtu kaya ing ngisor iki:
Pisanan, pretreatment bahan baku. Bahan mentah bubuk sing ngemot pati tartamtu (luwih saka 20%) dicampur seragam miturut rumus, banjur dikirim menyang piranti tempering kanggo perawatan tempering. Tujuan tempering yaiku nyetel isi kelembapan lan suhu bahan, supaya bahan bisa tekan negara becik sadurunge ngetik extruder. Umume, isi Kelembapan saka bahan sawise tempering dikontrol ing 10% ~ 27%, lan suhu mundhak dadi 70 ~ 98 ℃. Sajrone proses tempering, bahan nyerep banyu kanthi merata, sing kondusif kanggo gelatinisasi sabanjure pati lan denaturasi protein, lan uga bisa nyuda nyandhang saka meneng extruder lan tong minyak.
Kapindho, extrusion lan dadi panas. Bahan tempered mlebu rongga ekstrusi sekrup liwat piranti pakan. Rongga ekstrusi sekrup kasusun saka sekrup lan tong minyak, lan volume rongga ekstrusi mboko sithik mudhun ing arah sumbu. Nalika meneng muter, iku nyurung bahan maju terus-terusan, lan bahan sing mboko sithik teken ing tumindak meneng lan tong minyak, lan tekanan ing rongga ekstrusi mboko sithik mundhak. Rasio kompresi (rasio volume materi ing mburi dipakani kanggo volume ing mburi extrusion) bisa tekan 4~10, sing beda-beda miturut jinis panganan pet lan rumus bahan mentah.
Sajrone proses di-push lan extruded dening meneng, bahan kasebut kena gaya geser lan gaya gesekan sing kuwat. Gaya geser digawe dening gerakan relatif antarane meneng lan tong minyak, uga antarane flights meneng. Bisa ngilangi partikel bahan kasebut, nggawe bahan mentahan lan aditif nyampur luwih seragam, lan ningkatake gelatinisasi pati lan denaturasi protein. Gaya gesekan digawe antarane bahan lan tembok njero tong minyak, uga antarane partikel materi, sing bisa ngasilake panas banget, sing kondusif kanggo dadi panas saka bahan. Kajaba iku, miturut kabutuhan pangolahan, uap bisa mili liwat jaket tong minyak kanggo panas bahan antarane tembok, supaya bahan ing rongga extrusion ana ing suhu dhuwur lan negara tekanan dhuwur. Suhu ing rongga ekstrusi umume dikontrol ing 120 ~ 180 ℃, lan tekanan dikontrol ing 2 ~ 10MPa.
Katelu, gelatinisasi pati lan denaturasi protein. Ing tumindak suhu dhuwur, tekanan dhuwur lan gaya geser, pati ing bahan nyerep banyu lan ngembang, struktur kristal wis numpes, lan diowahi dadi negara amorf, kang diarani gelatinisasi pati. gelatinisasi pati bisa nambah pencernaan panganan pet, amarga pati gelatinisasi luwih gampang diurai dening enzim pencernaan pets. Ing wektu sing padha, pati gelatinized uga bisa nambah viskositas lan pasukan naleni bahan, nggawe produk extruded duwe wangun lan tekstur apik.
Saliyane gelatinisasi pati, protein ing bahan uga bakal ngalami denaturasi ing tumindak suhu dhuwur lan tekanan dhuwur. Denaturasi protein nuduhake owah-owahan struktur spasial molekul protein tanpa ngganti struktur primer., sing bisa nambah kelarutan lan digestibility protein, lan nggawe panganan pet duwe rasa sing luwih apik. Ing wektu sing padha, 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.
Kaping papat, 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, 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. Contone, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
kaping lima, post-processing. The extruded puffed particles need to go through post-processing links such as drying, pendinginan, 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. Pendinginan yaiku nyuda suhu partikel sing garing nganti suhu kamar, nyegah prodhuk saka caking lan deteriorating. Bumbu yaiku kanggo nyemprotake agen penyedap, attractants lan aditif liyane ing lumahing partikel kanggo nambah palatability prodhuk. Packaging yaiku kanggo ngemas partikel sing wis dirasakake menyang tas utawa kaleng kanggo njamin kebersihan lan safety produk lan nggampangake panyimpenan lan transportasi..
2.3 Faktor Kunci Ngaruhi Screw Extrusion Puffing Effect
Efek saka ekstrusi sekrup puffing langsung mengaruhi kualitas panganan pet. Ana akeh faktor sing mengaruhi efek puffing, utamane kalebu karakteristik bahan mentah, paramèter tempering, paramèter ekstrusi lan struktur sirah mati. 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 Karakteristik Bahan Baku:
Jinis, ukuran partikel, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Contone, 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, umume 80-100 bolong. 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%. Yen isi Kelembapan dhuwur banget, 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 menit, 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. Contone, 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 kanggo 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. Nanging, yen kacepetan meneng dhuwur banget, wektu panggonan saka bahan ing growong extrusion cendhak banget, resulting in incomplete starch gelatinization and uneven mixing; yen kacepetan meneng banget kurang, gaya geser lan gaya gesekan ora cukup, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: bagean dipakani, 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, ukuran bolongan die lan kacepetan meneng. Sing luwih dhuwur tekanan ekstrusi, the better the puffing effect, but if the pressure is too high, bakal nambah konsumsi energi lan nyandhang peralatan; yen meksa banget kurang, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 Struktur Kepala Die:
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. Sing liyane nomer bolongan mati, luwih dhuwur kapasitas produksi, nanging perlu kanggo mesthekake yen distribusi tekanan seragam, supaya supaya ora puffing ora rata saka prodhuk.
