1.2 घरपालुवा जनावरको खाना र यसको प्रशोधन विशेषताहरूको वर्गीकरण

घरपालुवा जनावरको खानामा विभिन्न वर्गीकरण विधिहरू छन्, which can be divided into different types according to processing technology, water content, product form and use. ती मध्ये, according to the processing technology and water content, pet food is mainly divided into dry puffed products, semi-wet products, soft puffed products, wet canned products and snacks (or treats). Each type of pet food has its own unique processing characteristics and requirements for equipment, as follows:

1.2.1 Dry Puffed Products:

Dry puffed pet food is the most common type of pet food, with a water content of 10%-12%. Its main raw materials include meat meal, fish meal, cereal (corn, wheat, rice), soybean meal, भिटामिन, minerals and other additives. The processing process of dry puffed products is closely related to the puffing process, which requires the use of extrusion puffing equipment to process the raw materials into granular products with uniform size, crisp taste and good palatability. The characteristics of dry puffed products are long shelf life, convenient storage and transportation, and low production cost, which are suitable for large-scale production and popular among pet owners.

The key processing requirement of dry puffed products is that the raw materials need to be fully puffed, so that the starch in the raw materials is fully gelatinized, which is conducive to the digestion and absorption of pets. एकै समयमा, the product needs to have a certain hardness and crispness to meet the chewing needs of pets and help clean their teeth. This puts high requirements on the extrusion pressure, temperature and screw speed of the extruder.

1.2.2 Semi-Wet Products:

Semi-wet pet food has a water content of 25%-35%, which is between dry and wet products. Its raw materials are similar to dry puffed products, but more humectants (such as propylene glycol, sorbitol) are added to maintain the softness and moisture of the product. The processing process of semi-wet products also needs puffing treatment, but the puffing degree is lower than that of dry products. The product has the characteristics of soft taste and good palatability, which is suitable for pets with poor chewing ability (such as elderly pets, sick pets).

The processing difficulty of semi-wet products lies in the control of water content and the prevention of product deterioration. त्यसैले, in the processing process, it is necessary to strictly control the temperature and humidity of each link, र उत्पादनको शेल्फ जीवन सुनिश्चित गर्न उपयुक्त संरक्षक र humectants चयन गर्नुहोस्.

1.2.3 नरम पफ्ड उत्पादनहरू:

नरम पफ्ड पाल्तु खानामा पानीको मात्रा हुन्छ 15%-25%, जुन सुक्खा पफ्ड र अर्ध-गीले उत्पादनहरू बीचको उत्पादन हो. यसको प्रशोधन प्रक्रिया सुक्खा पफ्ड उत्पादनहरू जस्तै छ, तर उत्पादनलाई नरम र लोचदार बनाउन सूत्र र बाहिर निकाल्ने मापदण्डहरू समायोजन गरिन्छ. नरम पफ्ड उत्पादनहरूले सुख्खा र अर्ध-गीला उत्पादनहरूको फाइदाहरू संयोजन गर्दछ, राम्रो स्वाद र सजिलो पाचन संग, जुन विभिन्न प्रकारका घरपालुवा जनावरहरूको लागि उपयुक्त छ.

1.2.4 भिजेको डिब्बाबंद उत्पादनहरू:

भिजेको डिब्बाबंद पाल्तु खानामा पानीको मात्रा बढी हुन्छ 70%, मुख्यतया ताजा मासु प्रयोग, माछा, तरकारी र अन्य कच्चा माल, जसलाई खाना पकाएर प्रशोधन गरिन्छ, क्यानिङ, नसबंदी र अन्य प्रक्रियाहरू. अन्य प्रकारका उत्पादनहरू भन्दा फरक, भिजेको डिब्बाबंद उत्पादनहरूलाई पफिङ उपचारको आवश्यकता पर्दैन, र तिनीहरूको मुख्य प्रशोधन लिङ्कहरू खाना पकाउने र नसबंदी हुन्. उत्पादनमा समृद्ध पोषणको विशेषताहरू छन्, बलियो स्वाद र उच्च आर्द्रता सामग्री, जुन पानी पिउन मन नपर्ने वा पूरक पोषण चाहिने घरपालुवा जनावरहरूको लागि उपयुक्त छ.

भिजेको डिब्बाबंद उत्पादनहरूको प्रशोधनको कुञ्जी भनेको कच्चा मालको ताजापन र सुरक्षा सुनिश्चित गर्नु हो, र उत्पादनमा हानिकारक ब्याक्टेरियाहरू मार्न र शेल्फ जीवन विस्तार गर्न नसबंदी तापमान र समयलाई कडाइका साथ नियन्त्रण गर्नुहोस्।. एकै समयमा, यो सुनिश्चित गर्न आवश्यक छ कि खाना पकाउने र नसबंदी प्रक्रियाको समयमा उत्पादनको पोषण तत्वहरू हराएको छैन।.

1.2.5 पालतू खाजा (वा व्यवहार गर्दछ):

पाल्तु स्न्याक्स घरपालुवा जनावरहरूको लागि सहायक खाना हो, मुख्य रूपमा घरपालुवा जनावरहरूलाई पुरस्कृत गर्न प्रयोग गरिन्छ, तिनीहरूको मूड र पूरक पोषण सुधार. पाल्तु जनावर खाजा को प्रकार विविध छन्, पफ्ड स्न्याक्स सहित, सुकेको मासु खाजा, झटका खाजा, दाँतको खाजा, आदि. ती मध्ये, पफ्ड स्न्याक्स एक ठूलो अनुपात को लागी खाता, र तिनीहरूको प्रशोधन प्रक्रिया सुख्खा पफ्ड उत्पादनहरू जस्तै छ, तर सूत्र थप परिष्कृत छ, र अधिक स्वाद एजेन्टहरू र कार्यात्मक additives स्वाद र घरपालुवा जनावरहरूको कार्यात्मक आवश्यकताहरू पूरा गर्न थपिन्छन्।.

पाल्तु खाजामा स्वादको लागि उच्च आवश्यकताहरू छन्, उपस्थिति र कार्यक्षमता. उदाहरणका लागि, दाँतको खाजामा घरपालुवा जनावरको दाँत सफा गर्न र डेन्टल क्यालकुलसलाई रोक्न मद्दत गर्नको लागि निश्चित कठोरता र बनावट हुनु आवश्यक छ।; कपाल-सुन्दर स्न्याक्सले घरपालुवा जनावरको कपालको गुणस्तर सुधार गर्न मद्दत गर्न लेसिथिन जस्ता सामग्रीहरू थप्न आवश्यक छ।. यसका लागि एक्स्ट्रुडरसँग विभिन्न प्रकारका खाजाहरूको प्रशोधन आवश्यकताहरू पूरा गर्न राम्रो लचिलोपन र समायोजन योग्यता आवश्यक छ।.

यो ध्यान दिन लायक छ कि डिब्बाबंद उत्पादनहरु बाहेक, धेरै प्रकारका पाल्तु जनावरहरूको खाना पफिंग प्रक्रियासँग नजिकबाट सम्बन्धित छन्. पफिङ पाल्तु जनावरको खाना प्रशोधनको मुख्य भाग मात्र होइन, तर गुणस्तरमा पनि प्रत्यक्ष असर गर्छ, स्वाद, पाल्तु जनावरको खानाको पोषण र पाचन क्षमता. त्यसैले, सही बाहिर निकाल्ने उपकरण छनोट गर्ने र वैज्ञानिक निकासी प्रविधिमा निपुणता पाल्तु जनावर खाद्य प्रशोधन उद्यमहरूको लागि महत्त्वपूर्ण छ।.

2. पाल्तु जनावर खाद्य प्रशोधन को कोर प्रविधि: एक्सट्रुजन पफिंग टेक्नोलोजी

एक्सट्रुजन पफिंग टेक्नोलोजी एक प्रमुख प्रशोधन प्रविधि हो जुन मिश्रणलाई एकीकृत गर्दछ, घुट्ने, तताउने, बाहिर निकाल्ने र पफिंग. यो व्यापक रूपमा घरपालुवा जनावरको खानाको उत्पादनमा प्रयोग गरिएको छ किनभने यसको उच्च उत्पादन क्षमताको फाइदाहरू छन्, राम्रो उत्पादन गुणस्तर, कच्चा माल र व्यापक आवेदन दायरा बलियो अनुकूलन. पाल्तु जनावर खाना को प्रशोधन मा, एक्सट्रुजन टेक्नोलोजी मुख्यतया कच्चा मालको पफिंग महसुस गर्न प्रयोग गरिन्छ, स्टार्च जिलेटिनाइज बनाउनुहोस्, प्रोटीन विकृति, र उत्पादनको स्वाद र पाचन क्षमता सुधार गर्दछ. एकै समयमा, यसले कच्चा पदार्थमा भएका हानिकारक ब्याक्टेरियालाई पनि मार्न सक्छ, घरपालुवा जनावरको खानाको सुरक्षा सुनिश्चित गर्नुहोस्.

2.1 पाल्तु जनावर खाद्य कच्चा माल को विशेषताहरु र एक्स्ट्रुजन उपकरण को लागी आवश्यकताहरु

घरपालुवा जनावरको खानाको कच्चा माल मुख्यतया मासु उत्पादनहरू हुन् (जस्तै मासु खाना, fish meal, ताजा मासु), cereal, soybean meal, भिटामिन, minerals and other additives. ती मध्ये, मासु उत्पादन एक ठूलो अनुपात को लागी खाता, उत्पादन बलियो चिपचिपापन छ बनाउन. यो विशेषताले बाहिर निकाल्ने उपकरणको लागि विशेष आवश्यकताहरू राख्छ:

एकल-स्क्रू एक्स्ट्रुडरहरू घरपालुवा जनावरको खानाको आर्थिक उत्पादनको लागि उपयुक्त छैनन्. किनभने एकल-स्क्रू एक्स्ट्रुडरको साँघुरो कतरनी दायरा छ, खराब पम्पिङ क्षमता र कुनै आत्म-सफाई प्रभाव. मासु उत्पादनहरू जस्ता चिपचिपा सामग्रीहरू प्रशोधन गर्दा, सामग्री संचय गर्न सजिलो छ, एक्स्ट्रुडर ब्यारेलमा अवरोध र असमान मिश्रण, जसले उत्पादन क्षमतालाई मात्र असर गर्दैन, तर यसले उत्पादनको गुणस्तरलाई पनि अस्थिर बनाउँछ. साथै, उच्च-फ्याट र उच्च-प्रोटिन कच्चा माल प्रशोधन गर्दा एकल-स्क्रू एक्स्ट्रुडरमा उच्च ऊर्जा खपत हुन्छ।, जसले उद्यमहरूको उत्पादन लागत बढाउँछ.

ट्विन-स्क्रू एक्स्ट्रूडरहरू, अर्कोतर्फ, घरपालुवा जनावरको खाद्य उत्पादनमा स्पष्ट फाइदाहरू छन्. तिनीहरूसँग फराकिलो कतरनी दायरा छ, अधिक प्रभावकारी पम्पिङ प्रभाव र आत्म-सफाई प्रभाव, जसले प्रभावकारी रूपमा सामग्री चिपचिपापन र संचयको समस्याहरू समाधान गर्न सक्छ. जुम्ल्याहा-स्क्रू एक्स्ट्रुडरले समान मिश्रणलाई महसुस गर्न सक्छ, सामाग्री को घुट्ने र बाहिर निकाल्ने, उच्च बोसो र ताजा मासु सामग्री संग कच्चा माल प्रशोधन गर्दा पनि, यसले स्थिर उत्पादन र लगातार उत्पादन गुणस्तर सुनिश्चित गर्न सक्छ. त्यसैले, घरपालुवा जनावरको खानाको वास्तविक उत्पादनमा, जुम्ल्याहा-स्क्रू एक्स्ट्रुडरहरू घरपालुवा जनावरको खाना पफिंगको मुख्य माध्यम बनेका छन्, र व्यापक रूपमा सुख्खा पफ्ड उत्पादनहरूको उत्पादनमा प्रयोग गरिन्छ, semi-wet products, नरम पफ्ड उत्पादनहरू र पाल्तु जनावर खाजा.

2.2 स्क्रू एक्सट्रुजन पफिंगको कार्य सिद्धान्त

घरपालुवा जनावरको खानाको स्क्रू एक्स्ट्रुजन पफिंग प्रक्रिया एक जटिल भौतिक र रासायनिक प्रक्रिया हो, जसमा तापमान जस्ता धेरै कारकहरूको अन्तरक्रिया समावेश हुन्छ, दबाब, कतरनी बल र समय. विशेष कार्य सिद्धान्त निम्नानुसार छ:

पहिले, कच्चा माल पूर्व उपचार. एक निश्चित मात्रामा स्टार्च भएको पाउडररी कच्चा माल (भन्दा बढी 20%) सूत्र अनुसार समान रूपमा मिश्रित छन्, र त्यसपछि टेम्परिङ उपचारको लागि टेम्परिङ उपकरणमा पठाइयो. टेम्परिङको उद्देश्य सामग्रीको आर्द्रता र तापक्रम समायोजन गर्नु हो, ताकि सामग्रीहरू एक्स्ट्रुडरमा प्रवेश गर्नु अघि आदर्श स्थितिमा पुग्न सक्छ. सामान्यतया, टेम्परिङ पछि सामग्रीको आर्द्रता 10% -27% मा नियन्त्रण गरिन्छ, र तापमान 70 ~ 98 ℃ मा बढाइएको छ. tempering प्रक्रिया को समयमा, सामग्रीले समान रूपमा पानी अवशोषित गर्दछ, जुन स्टार्चको जिलेटिनाइजेशन र प्रोटिनको विकृतिकरणको लागि अनुकूल छ, र एक्स्ट्रुडर स्क्रू र ब्यारेलको पहिरन पनि कम गर्न सक्छ.

दोस्रो, बाहिर निकाल्ने र तताउने. टेम्पर्ड सामग्रीहरू फिडिंग उपकरण मार्फत स्क्रू एक्सट्रुजन गुहामा प्रवेश गर्दछ. स्क्रू एक्सट्रुजन गुहा पेंच र ब्यारेलबाट बनेको हुन्छ, र एक्सट्रुजन गुहाको भोल्युम बिस्तारै अक्ष दिशामा घट्दै जान्छ. जब पेंच घुम्छ, यसले सामग्रीहरूलाई निरन्तर अगाडि बढाउँछ, र सामग्रीहरू बिस्तारै स्क्रू र ब्यारेलको कार्य अन्तर्गत संकुचित हुन्छन्, र एक्सट्रुजन गुहामा दबाब बिस्तारै बढ्दै जान्छ. कम्प्रेसन अनुपात (फिडिङ अन्त्यमा सामग्रीको भोल्युम र एक्सट्रुजन अन्त्यमा भोल्युमको अनुपात) 4-10 सम्म पुग्न सक्छ, जुन पाल्तु जनावरको खानाको प्रकार र कच्चा मालको सूत्र अनुसार फरक हुन्छ.

स्क्रू द्वारा धकेलिएको र बाहिर निकाल्ने प्रक्रियाको क्रममा, सामग्रीहरू बलियो कतरनी बल र घर्षण बलको अधीनमा छन्. शियर बल पेंच र ब्यारेल बीचको सापेक्ष आन्दोलन द्वारा उत्पन्न हुन्छ, साथै स्क्रू उडानहरू बीच. यसले सामग्रीको कणहरू तोड्न सक्छ, कच्चा माल र additives थप समान रूपमा मिश्रण बनाउन, र स्टार्चको जिलेटिनाइजेशन र प्रोटिनको विकृतिकरणलाई बढावा दिन्छ. घर्षण बल सामग्री र ब्यारेल को भित्री पर्खाल बीच उत्पन्न हुन्छ, साथै भौतिक कणहरू बीच, जसले धेरै गर्मी उत्पन्न गर्न सक्छ, जो सामग्री को तताउन अनुकूल छ. साथै, प्रशोधन आवश्यकता अनुसार, पर्खालहरू बीचको सामग्रीलाई तातो बनाउन ब्यारेल ज्याकेटको माध्यमबाट स्टीम प्रवाह हुन सक्छ, ताकि बाहिर निकाल्ने गुहामा भएका सामग्रीहरू उच्च-तापमान र उच्च-दबावको अवस्थामा छन्. बाहिर निकाल्ने गुहा मा तापमान सामान्यतया 120 ~ 180 ℃ मा नियन्त्रण गरिन्छ, र दबाव 2～10MPa मा नियन्त्रण गरिन्छ.

तेस्रो, स्टार्च जिलेटिनाइजेशन र प्रोटीन विकृतीकरण. उच्च तापमान को कार्य अन्तर्गत, उच्च दबाव र कतरनी बल, सामग्रीमा रहेको स्टार्चले पानी सोस्छ र विस्तार हुन्छ, क्रिस्टल संरचना नष्ट भएको छ, र यो अनाकार अवस्था मा परिणत हुन्छ, जसलाई स्टार्च जिलेटिनाइजेशन भनिन्छ. स्टार्च जिलेटिनाइजेशनले घरपालुवा जनावरको खानाको पाचन क्षमता सुधार गर्न सक्छ, किनभने जिलेटिनाइज्ड स्टार्च घरपालुवा जनावरहरूको पाचन इन्जाइमहरूद्वारा विघटन गर्न सजिलो हुन्छ. एकै समयमा, जिलेटिनाइज्ड स्टार्चले सामग्रीको चिपचिपापन र बाध्यकारी बललाई पनि सुधार गर्न सक्छ, extruded उत्पादनहरु राम्रो आकार र बनावट बनाउन.

स्टार्च जिलेटिनाइजेशनको अतिरिक्त, 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. एकै समयमा, 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.

चौथो, 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, सामग्रीको तापक्रम र दबाब तीव्र रूपमा घट्छ किनभने तिनीहरू अचानक एक्स्ट्रुजन गुहा छोड्छन् र सामान्य वायुमण्डलीय वातावरणमा प्रवेश गर्छन्।. दबाब भिन्नता र तापमान भिन्नता को संयुक्त कार्य अन्तर्गत, सामग्रीमा पानी छिटो वाष्पीकरण हुन्छ, सामग्रीको मात्रा द्रुत रूपमा विस्तार हुन्छ (विस्तार दर 2～8 पटक पुग्न सक्छ), र सामग्रीहरू निर्जलित हुन्छन् र छिट्टै ठोस बनाइन्छ, कुरकुरा वा नरम पफ्ड उत्पादन.

डाइ प्वालबाट बाहिर निकालेपछि, पफ्ड सामग्रीहरू काट्ने यन्त्रद्वारा समान लम्बाइको छोटो कणहरूमा काटिन्छन् (रोटरी चक्कु) टाउको मा स्थापित. कणहरूको लम्बाइ विभिन्न प्रकारका पाल्तु खानाको आवश्यकताहरू पूरा गर्न रोटरी चक्कुको गति परिवर्तन गरेर समायोजन गर्न सकिन्छ।. उदाहरणका लागि, कुकुरको खानाका कणहरू साना र छोटो हुन्छन्, जबकि वयस्क कुकुरको खानाको कणहरू ठूला र लामो हुन्छन्.

पाँचौं, पोस्ट-प्रशोधन. बाहिर निकालिएको पफ्ड कणहरू सुकाउने जस्ता पोस्ट-प्रोसेसिङ लिङ्कहरू मार्फत जान आवश्यक छ, चिसो, मसला र प्याकेजिङ्ग अन्तिम पाल्तु खाना उत्पादन बन्न. सुकाउने भनेको कणहरूको पानीको सामग्रीलाई मानक दायरामा घटाउनु हो (10%-12% सुक्खा उत्पादनहरु को लागी), ताकि उत्पादनको शेल्फ जीवन विस्तार गर्न. कूलिङ भनेको सुख्खा कणहरूको तापक्रमलाई कोठाको तापक्रममा घटाउनु हो, उत्पादनलाई केकिंग र बिग्रनबाट रोक्नुहोस्. सिजनिङ भनेको स्वाद बढाउने एजेन्टहरू स्प्रे गर्नु हो, उत्पादनको स्वादिष्टता सुधार गर्न कणहरूको सतहमा आकर्षक र अन्य additives. प्याकेजिङ भनेको उत्पादनको सरसफाइ र सुरक्षा सुनिश्चित गर्न र भण्डारण र ढुवानीलाई सहज बनाउन मौसमी कणहरूलाई झोला वा क्यानहरूमा प्याक गर्नु हो।.

2.3 स्क्रू एक्सट्रुजन पफिङ प्रभावलाई असर गर्ने मुख्य कारकहरू

स्क्रू एक्सट्रुजन पफिंगको प्रभावले घरपालुवा जनावरको खानाको गुणस्तरलाई सीधा असर गर्छ. पफिंग प्रभावलाई असर गर्ने धेरै कारकहरू छन्, मुख्यतया कच्चा माल विशेषताहरु सहित, टेम्परिङ प्यारामिटरहरू, एक्सट्रुजन प्यारामिटरहरू र टाउको संरचना. यी मुख्य कारकहरू मास्टर गर्न र वैज्ञानिक समायोजनहरू पफिङ प्रभावको स्थिरता र उत्पादन गुणस्तरको स्थिरता सुनिश्चित गर्न सक्छ।.

2.3.1 कच्चा माल विशेषताहरु:

प्रकार, कण आकार, आर्द्रता सामग्री र कच्चा मालको पोषण संरचनाले पफिङ प्रभावमा ठूलो प्रभाव पार्छ. उदाहरणका लागि, कच्चा मालको स्टार्च सामग्रीले उत्पादनको विस्तार दरलाई प्रत्यक्ष असर गर्छ. स्टार्च सामग्री उच्च हुन्छ (एक निश्चित दायरा भित्र), पफिंग प्रभाव राम्रो, and the larger the expansion rate of the product. The particle size of raw materials should be uniform, generally 80-100 जाल. 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%. यदि नमी सामग्री धेरै उच्च छ, 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, टेम्परिंग समय र टेम्परिंग पछि नमी सामग्री. टेम्परिंग तापमान सामान्यतया 70 ~ 98 ℃ छ. यदि tempering तापमान धेरै कम छ, सामग्रीले समान रूपमा पानी अवशोषित गर्न सक्दैन, र स्टार्च जिलेटिनाइजेशन अपर्याप्त छ; यदि tempering तापमान धेरै उच्च छ, सामाग्री अग्रिम केक हुन सक्छ, पछिको निकासीलाई असर गर्छ. टेम्परिंग समय सामान्यतया छ 2-5 मिनेट, जसलाई कच्चा पदार्थको प्रकार र आर्द्रताको मात्रा अनुसार समायोजन गर्नुपर्छ. टेम्परिङ पछि आर्द्रता सामग्री 10% - 27%, जुन घरपालुवा जनावरको खानाको प्रकार अनुसार फरक हुन्छ. उदाहरणका लागि, टेम्परिंग पछि सुख्खा पफ्ड उत्पादनहरु को आर्द्रता को मात्रा सामान्यतया छ 15%-20%, जबकि अर्ध-गीला उत्पादनहरु को छ 22%-27%.

2.3.3 एक्सट्रुजन प्यारामिटरहरू:

एक्स्ट्रुजन प्यारामिटरहरू पफिङ प्रभावलाई असर गर्ने सबैभन्दा महत्त्वपूर्ण कारकहरू हुन्, मुख्यतया पेंच गति सहित, बाहिर निकाल्ने तापमान र बाहिर निकाल्ने दबाव. स्क्रू गति सामान्यतया दायरा बाट 100 को 600 आरपीएम. उच्च पेंच गति, सामग्रीले प्राप्त गरेको कतरन बल र घर्षण बल जति बढी हुन्छ, बाहिर निकाल्ने तापमान र दबाब उच्च, र पफिंग प्रभाव राम्रो. यद्यपि, यदि स्क्रू गति धेरै उच्च छ, बाहिर निकाल्ने गुहा मा सामाग्री को निवास समय धेरै छोटो छ, अपूर्ण स्टार्च जिलेटिनाइजेशन र असमान मिश्रणको परिणामस्वरूप; यदि स्क्रू गति धेरै कम छ, कतरन बल र घर्षण बल अपर्याप्त छन्, र पफिंग प्रभाव खराब छ.

बाहिर निकाल्ने तापमान सामान्यतया 120 ~ 180 ℃ मा नियन्त्रण गरिन्छ, जसलाई तीन खण्डमा विभाजन गरिएको छ: खुवाउने खण्ड, पिघलने खण्ड र homogenizing खण्ड. खुवाउने खण्डको तापमान कम छ (7090 ℃), 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. बाहिर निकाल्ने गुहामा दबाब मुख्यतया पेंच को कम्प्रेसन अनुपात द्वारा निर्धारण गरिन्छ, डाइ प्वाल आकार र स्क्रू गति. बाहिर निकाल्ने दबाव जति उच्च हुन्छ, पफिंग प्रभाव राम्रो, but if the pressure is too high, यसले उपकरणको ऊर्जा खपत र पहिरन बढाउनेछ; यदि दबाव धेरै कम छ, the puffing effect is poor, and the product is loose and easy to break.

2.3.4 टाउकोको संरचना:

डाइ हेड संरचनामा मुख्यतया संख्या समावेश छ, डाइ प्वालहरूको आकार र आकार. डाइ होलको आकारले पफ्ड उत्पादनको क्रस-सेक्शनल आकार निर्धारण गर्दछ, जस्तै गोलाकार, वर्ग, त्रिकोणीय र अन्य आकारहरू. डाइ प्वालको साइजले उत्पादनको प्रारम्भिक व्यास निर्धारण गर्दछ. डाइ होल साइज जति सानो हुन्छ, बाहिर निकाल्ने दबाब जति धेरै हुन्छ, र पफिंग प्रभाव राम्रो, तर उत्पादन क्षमता घट्नेछ. डाइ प्वालहरूको संख्याले उत्पादन क्षमतालाई असर गर्छ. डाइ होलको संख्या जति धेरै हुन्छ, उच्च उत्पादन क्षमता, तर दबाब वितरण समान छ भनेर सुनिश्चित गर्न आवश्यक छ, उत्पादनको असमान पफिंगबाट बच्न.
