2.2 ຫຼັກການການເຮັດວຽກຂອງ Screw Extrusion Puffing
ຂະບວນການຂັດສະກູ extrusion puffing ຂອງອາຫານສັດລ້ຽງແມ່ນຂະບວນການທາງດ້ານຮ່າງກາຍແລະເຄມີທີ່ຊັບຊ້ອນ, ເຊິ່ງກ່ຽວຂ້ອງກັບການໂຕ້ຕອບຂອງປັດໃຈຫຼາຍຢ່າງເຊັ່ນ: ອຸນຫະພູມ, ຄວາມກົດດັນ, ແຮງຕັດແລະເວລາ. ຫຼັກການການເຮັດວຽກສະເພາະແມ່ນດັ່ງຕໍ່ໄປນີ້:
ທໍາອິດ, pretreatment ວັດຖຸດິບ. ວັດຖຸດິບທີ່ເປັນຝຸ່ນທີ່ມີຈໍານວນທີ່ແນ່ນອນຂອງທາດແປ້ງ (ຫຼາຍກວ່າ 20%) ແມ່ນປະສົມເປັນເອກະພາບຕາມສູດ, ແລະຫຼັງຈາກນັ້ນຖືກສົ່ງໄປຫາອຸປະກອນ tempering ສໍາລັບການປິ່ນປົວ tempering. ຈຸດປະສົງຂອງ tempering ແມ່ນເພື່ອປັບຄວາມຊຸ່ມຊື່ນແລະອຸນຫະພູມຂອງວັດສະດຸ, ເພື່ອໃຫ້ວັດສະດຸສາມາດບັນລຸສະພາບທີ່ເຫມາະສົມກ່ອນທີ່ຈະເຂົ້າໄປໃນ extruder. ໂດຍທົ່ວໄປ, ຄວາມຊຸ່ມຊື່ນຂອງອຸປະກອນການຫຼັງຈາກ tempering ໄດ້ຖືກຄວບຄຸມຢູ່ທີ່ 10% ~ 27%, ແລະອຸນຫະພູມແມ່ນເພີ່ມຂຶ້ນເປັນ 70 ~ 98 ℃. ໃນລະຫວ່າງການຂະບວນການ tempering, the materials absorb water evenly, which is conducive to the subsequent gelatinization of starch and denaturation of protein, and can also reduce the wear of the extruder screw and barrel.
ທີສອງ, extrusion and heating. The tempered materials enter the screw extrusion cavity through the feeding device. The screw extrusion cavity is composed of a screw and a barrel, ແລະປະລິມານຂອງຮູ extrusion ຄ່ອຍໆຫຼຸດລົງຕາມທິດທາງແກນ. When the screw rotates, it pushes the materials forward continuously, and the materials are gradually compressed under the action of the screw and the barrel, ແລະຄວາມກົດດັນໃນຮູ extrusion ຄ່ອຍໆເພີ່ມຂຶ້ນ. The compression ratio (the ratio of the volume of the material at the feeding end to the volume at the extrusion end) can reach 4～10, which varies according to the type of pet food and the formula of raw materials.
During the process of being pushed and extruded by the screw, ວັດສະດຸແມ່ນຂຶ້ນກັບຜົນບັງຄັບໃຊ້ shear ທີ່ເຂັ້ມແຂງແລະຜົນບັງຄັບໃຊ້ friction. ຜົນບັງຄັບໃຊ້ shear ແມ່ນຜະລິດໂດຍການເຄື່ອນໄຫວທີ່ກ່ຽວຂ້ອງລະຫວ່າງ screw ແລະ barrel ໄດ້, ເຊັ່ນດຽວກັນກັບການບິນລະຫວ່າງສະກູ. ມັນສາມາດທໍາລາຍອະນຸພາກຂອງວັດສະດຸ, ເຮັດໃຫ້ວັດຖຸດິບ ແລະ ທາດປະສົມປະສົມກັນຫຼາຍຂື້ນ, ແລະສົ່ງເສີມການ gelatinization ຂອງທາດແປ້ງແລະ denaturation ຂອງທາດໂປຼຕີນ. ຜົນບັງຄັບໃຊ້ friction ແມ່ນຜະລິດລະຫວ່າງວັດສະດຸແລະກໍາແພງພາຍໃນຂອງຖັງ, ເຊັ່ນດຽວກັນກັບລະຫວ່າງອະນຸພາກວັດສະດຸ, ເຊິ່ງສາມາດສ້າງຄວາມຮ້ອນໄດ້ຫຼາຍ, ທີ່ເອື້ອອໍານວຍຕໍ່ການໃຫ້ຄວາມຮ້ອນຂອງວັດສະດຸ. ນອກຈາກນັ້ນ, ອີງຕາມຄວາມຕ້ອງການຂອງການປຸງແຕ່ງ, ອາຍສາມາດໄຫຼຜ່ານກະເປົ໋າຖັງເພື່ອໃຫ້ຄວາມຮ້ອນຂອງວັດສະດຸລະຫວ່າງຝາ, ເພື່ອໃຫ້ວັດສະດຸຢູ່ໃນຮູ extrusion ຢູ່ໃນສະພາບທີ່ມີອຸນຫະພູມສູງແລະຄວາມກົດດັນສູງ. The temperature in the extrusion cavity is generally controlled at 120～180℃, and the pressure is controlled at 2～10MPa.
ທີສາມ, starch gelatinization and protein denaturation. Under the action of high temperature, high pressure and shear force, the starch in the materials absorbs water and expands, the crystal structure is destroyed, and it is converted into an amorphous state, which is called starch gelatinization. Starch gelatinization can improve the digestibility of pet food, because the gelatinized starch is easier to be decomposed by the digestive enzymes of pets. ໃນເວລາດຽວກັນ, 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, ທາດໂປຼຕີນໃນວັດສະດຸຍັງຈະໄດ້ຮັບການ denaturation ພາຍໃຕ້ການປະຕິບັດຂອງອຸນຫະພູມສູງແລະຄວາມກົດດັນສູງ. ທາດໂປຼຕີນຈາກ denaturation ຫມາຍເຖິງການປ່ຽນແປງໂຄງສ້າງທາງກວ້າງຂອງໂມເລກຸນທາດໂປຼຕີນໂດຍບໍ່ມີການປ່ຽນແປງໂຄງສ້າງຕົ້ນຕໍ., ເຊິ່ງສາມາດປັບປຸງການລະລາຍແລະການຍ່ອຍອາຫານຂອງທາດໂປຼຕີນ, ແລະເຮັດໃຫ້ອາຫານສັດລ້ຽງມີ palatability ທີ່ດີກວ່າ. ໃນເວລາດຽວກັນ, ທາດໂປຼຕີນຈາກ denatured ຍັງສາມາດປະກອບເປັນໂຄງສ້າງເຄືອຂ່າຍ, ເຊິ່ງສາມາດຫໍ່ທາດແປ້ງແລະສ່ວນປະກອບອື່ນໆ, ຊ່ວຍຮັກສາຮູບຮ່າງຂອງຜະລິດຕະພັນ puffed.
ສີ່, puffing ແລະຮູບຮ່າງ. ເມື່ອວັດສະດຸທີ່ຢູ່ໃນອຸນຫະພູມສູງແລະຄວາມກົດດັນສູງຖືກດັນໄປຫາຫົວຕາຍໂດຍສະກູແລະ extruded ຈາກຮູຕາຍດ້ວຍຄວາມໄວສູງ., 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. ຕົວຢ່າງ, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
ທີຫ້າ, post-processing. The extruded puffed particles need to go through post-processing links such as drying, ຄວາມເຢັນ, 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. ການຫຸ້ມຫໍ່ແມ່ນການຫຸ້ມຫໍ່ອະນຸພາກລະດູການໃສ່ຖົງຫຼືກະປ໋ອງເພື່ອຮັບປະກັນສຸຂະອະນາໄມແລະຄວາມປອດໄພຂອງຜະລິດຕະພັນແລະສະດວກໃນການເກັບຮັກສາແລະການຂົນສົ່ງ..
2.3 ປັດໃຈສໍາຄັນທີ່ມີຜົນກະທົບ Screw Extrusion Puffing Effect
ຜົນກະທົບຂອງ screw extrusion puffing ໂດຍກົງຜົນກະທົບຕໍ່ຄຸນນະພາບຂອງອາຫານສັດລ້ຽງ. ມີຫຼາຍປັດໃຈທີ່ມີຜົນກະທົບຕໍ່ຜົນກະທົບຂອງ puffing, ຕົ້ນຕໍລວມທັງຄຸນລັກສະນະວັດຖຸດິບ, ຕົວກໍານົດການ tempering, ຕົວກໍານົດການ extrusion ແລະໂຄງສ້າງຫົວຕາຍ. Mastering ປັດໃຈສໍາຄັນເຫຼົ່ານີ້ແລະເຮັດໃຫ້ການປັບຕົວທາງວິທະຍາສາດສາມາດຮັບປະກັນຄວາມຫມັ້ນຄົງຂອງຜົນກະທົບ puffing ແລະຄວາມສອດຄ່ອງຂອງຄຸນນະພາບຜະລິດຕະພັນ..
2.3.1 ລັກສະນະວັດຖຸດິບ:
ປະເພດ, ຂະໜາດອະນຸພາກ, ຄວາມຊຸ່ມຊື່ນແລະອົງປະກອບທາງໂພຊະນາການຂອງວັດຖຸດິບມີຜົນກະທົບຢ່າງຫຼວງຫຼາຍຕໍ່ຜົນກະທົບຂອງ puffing. ຕົວຢ່າງ, ເນື້ອໃນທາດແປ້ງຂອງວັດຖຸດິບມີຜົນກະທົບໂດຍກົງຕໍ່ອັດຕາການຂະຫຍາຍຕົວຂອງຜະລິດຕະພັນ. ປະລິມານທາດແປ້ງທີ່ສູງຂຶ້ນ (ພາຍໃນຂອບເຂດທີ່ແນ່ນອນ), ທີ່ດີກວ່າຜົນກະທົບ puffing, and the larger the expansion rate of the product. The particle size of raw materials should be uniform, ໂດຍທົ່ວໄປ 80-100 ຕາຫນ່າງ. 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%. ຖ້າຄວາມຊຸ່ມຊື່ນສູງເກີນໄປ, 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 ນາທີ, 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. ຕົວຢ່າງ, 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 ຕົວກໍານົດການ Extrusion:
Extrusion parameters are the most important factors affecting the puffing effect, ສ່ວນໃຫຍ່ລວມທັງຄວາມໄວ screw, ອຸນຫະພູມ extrusion ແລະຄວາມກົດດັນ extrusion. Screw speed generally ranges from 100 ກັບ 600 rpm. ຄວາມໄວຂອງ screw ສູງຂຶ້ນ, ຫຼາຍແຮງ shear ແລະແຮງ friction ທີ່ໄດ້ຮັບໂດຍວັດສະດຸ, the higher the extrusion temperature and pressure, and the better the puffing effect. ແນວໃດກໍ່ຕາມ, ຖ້າຄວາມໄວຂອງ screw ແມ່ນສູງເກີນໄປ, ເວລາທີ່ຢູ່ອາໄສຂອງວັດສະດຸໃນຮູ extrusion ແມ່ນສັ້ນເກີນໄປ, resulting in incomplete starch gelatinization and uneven mixing; ຖ້າຄວາມໄວຂອງສະກູຕໍ່າເກີນໄປ, ແຮງ shear ແລະແຮງ friction ບໍ່ພຽງພໍ, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: ພາກສ່ວນການໃຫ້ອາຫານ, melting section and homogenizing section. ອຸນຫະພູມຂອງພາກສ່ວນການໃຫ້ອາຫານແມ່ນຕ່ໍາ (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; ອຸນຫະພູມຂອງສ່ວນ melting ແມ່ນຂະຫນາດກາງ (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. ຄວາມກົດດັນໃນຮູ extrusion ສ່ວນໃຫຍ່ແມ່ນຖືກກໍານົດໂດຍອັດຕາສ່ວນການບີບອັດຂອງ screw ໄດ້, ຂະຫນາດຂຸມຕາຍແລະຄວາມໄວຂອງ screw. ຄວາມກົດດັນ extrusion ສູງຂຶ້ນ, ທີ່ດີກວ່າຜົນກະທົບ puffing, but if the pressure is too high, ມັນຈະເພີ່ມການບໍລິໂພກພະລັງງານແລະການສວມໃສ່ຂອງອຸປະກອນ; ຖ້າຄວາມກົດດັນຕໍ່າເກີນໄປ, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 ໂຄງສ້າງຫົວຕາຍ:
ໂຄງສ້າງຫົວຕາຍສ່ວນໃຫຍ່ແມ່ນປະກອບດ້ວຍຈໍານວນ, ຮູບຮ່າງແລະຂະຫນາດຂອງຮູຕາຍ. The shape of the die hole determines the cross-sectional shape of the puffed product, ເຊັ່ນ: ວົງ, ສີ່ຫຼ່ຽມ, triangular and other shapes. The size of the die hole determines the initial diameter of the product. ຂະຫນາດຂຸມຕາຍນ້ອຍລົງ, ຄວາມກົດດັນ extrusion ຫຼາຍ, and the better the puffing effect, ແຕ່ກຳລັງການຜະລິດຈະຫຼຸດລົງ. ຈໍານວນຂຸມຕາຍຜົນກະທົບຕໍ່ກໍາລັງການຜະລິດ. The more the number of die holes, ກໍາລັງການຜະລິດສູງຂຶ້ນ, ແຕ່ມັນເປັນສິ່ງຈໍາເປັນເພື່ອຮັບປະກັນວ່າການກະຈາຍຄວາມກົດດັນແມ່ນເປັນເອກະພາບ, so as to avoid uneven puffing of the product.
3. Extruders ຂອງພວກເຮົາ: Advantages and Product Series for Pet Food Production
