Ma'aunin Dorewa na Pellet (PDI) shine ma'aunin da masana'antar ciyarwa ke amfani da shi don ingancin jiki na pellet. Idan aka auna shi ta hanyar jefa samfurin pellets a cikin na'urar gwaji ta yau da kullun (hanyar Holmen pneumatic ko Kansas State tumbling can) da kuma ƙididdige kashi na pellets ɗin da ke nan, PDI yana shafar ingancin abinci kai tsaye, aikin dabbobi, da gamsuwar abokin ciniki. Pellets ɗin da ke wargajewa yayin sarrafawa suna haifar da tarar - ƙananan ƙwayoyin da dabbobi ke rarrabawa da ƙin su a kan gadon abinci - suna ɓatar da abinci, suna ƙara farashi a kowace kilogiram na karuwar nauyi, da kuma lalata daidaiton abinci mai gina jiki da masana abinci masu gina jiki suka tsara. Wannan labarin yana bincika abubuwan da ke tasiri ga PDI kuma yana gabatar da dabarun da za a iya aiwatarwa don ingantawa.
1. Tattalin Arzikin PDI
Rashin ingancin pellet yana haifar da sakamako mai kyau na kuɗi:
- Sharar Abinci. Tarar da aka ƙi a wurin ciyar da abinci tana wakiltar asarar abinci kai tsaye. A ayyukan kiwon shanu, tarar da aka samu yayin jigilar kaya da yawa akan tituna marasa kwalta na iya kaiwa kashi 5-15% na nauyin da aka kawo lokacin da PDI ya faɗi ƙasa da kashi 90%.
- Rage Aikin Dabbobi. Tsuntsaye da dabbobin da ke rarraba abincinsu suna cin abinci mara daidaito wanda ya bambanta da tsarin abinci mai gina jiki da aka tsara, wanda ke rage yawan girma da ingancin canza abincin.
- Kula da Abokan Ciniki. Masana'antar ciyar da abinci ta kasuwanci da ke samar da ayyukan kiwon kaji ko masu samar da dabbobi masu zaman kansu suna fuskantar hukuncin kwangila da kuma rage darajar abokan ciniki idan PDI ta faɗi ƙasa da ƙa'idodin kwangila.
Wani bincike da aka gudanar a Hongyang a Kazakhstan ya nuna alaƙar a sarari: lokacin da PDI na abincin shanu ya inganta daga kashi 88.7% zuwa kashi 94.2% (ƙarin kashi 5.5%), ƙarfin aiki na yau da kullun ya ƙaru daga tan 130 zuwa tan 178—haɓaka kashi 36.9% na yawan amfanin gona wanda kuma ya samar da ingantaccen ingancin pellet [1].
2. Nauyin Ma'auni: Menene ke Haifar da PDI?
Binciken masana'antu ya tabbatar da kimanin nauyin gudummawar da za a iya samu ga manyan abubuwa guda biyar da ke shafar dorewar pellet:
Ma'ana: Tsarin ciyarwa (halayen ɗaure sinadari). Kimanin Gudummawa ga PDI: 40%.
Ma'ana: Gyaran jiki (tururi, danshi, zafin jiki, lokaci). Kimanin Gudummawa ga PDI: 20%.
Ma'auni: Niƙa (rarraba girman barbashi). Kimanin Gudummawa ga PDI: 20%.
Ma'auni: Takamaiman ƙayyadaddun matsewar zobe (rabobin matsi, ƙirar rami). Kimanin Gudummawa ga PDI: 15%.
Ma'ana: Sanyaya da bushewa. Kimanin Gudummawa ga PDI: 5%.
Waɗannan ma'aunin kimantawa suna da ƙima kuma suna da takamaiman amfani, amma suna nuna wani muhimmin batu: sama da kashi ɗaya bisa uku na PDI ana ƙayyade su ta hanyar sigogi waɗanda za a iya gyarawa a injin niƙa pellet - yanayin sanyaya, niƙa, da ƙayyadaddun bayanai - suna mai da PDI ma'auni mai sarrafawa ga injin niƙa waɗanda ke son inganta ayyukansu.
3. Tsarin Ciyarwa: Ma'aunin 40%
Tsarin halitta shine babban abin da ke ba da gudummawa ga PDI, amma galibi shine mafi ƙarancin tsari - masana abinci mai gina jiki suna tsara aikin dabbobi da farashi, ba juriyar ƙwayoyin ba. Duk da haka, a cikin iyakokin abinci mai gina jiki, gyare-gyare da yawa na tsarin suna inganta PDI:
Abubuwan da ke cikin sitaci. Gelatin sitaci yayin gyaran fuska da kuma gyaran fuska yana samar da babban hanyar ɗaurewa. Tsarin da ke da yawan sitaci (masara, alkama, sha'ir) galibi ya fi kyau. Tsarin da aka yi da masara tare da fiye da kashi 60% na yawan masara yana amfana daga ƙarancin matsi (tsakanin 1:5) wanda ke ba da damar gelatin na sitaci ba tare da taurare saman ba [2].
Ƙarin Mai/Mai. Kitse yana aiki a matsayin mai mai yayin yin pellet, yana rage gogayya da matsin lamba. Yayin da shafa kitse bayan pellet yana inganta ingancin pellet ta hanyar shafa saman pellet, kitse mai yawa a cikin mashin da aka riga aka pellet (sama da 3%) yana rage PDI sosai ta hanyar tsoma baki ga haɗin furotin na sitaci. Dokar aiki: kada a ƙara fiye da kashi 1-2% na kitse a cikin mahaɗin; a shafa sauran kitse bayan pellet.
Tushen Sunadaran. Abubuwan haɗin halitta kamar alkama da wasu gutsuttsuran abincin waken soya suna inganta PDI ta hanyar cire sunadaran da kuma haɗa su yayin aikin pelleting. Sabanin haka, yawan tushen sunadaran da ba sa ɗaurewa (kamar abincin auduga) na iya rage PDI.
Zare. Matsakaicin matakan zare (3–8%) suna inganta ingancin kwale-kwale ta hanyar samar da matrix na tsari. Duk da haka, matakan zare masu yawa (sama da 10–12%) suna rage PDI saboda ƙwayoyin zare suna tsayayya da matsi kuma suna haifar da rauni a cikin tsarin kwale-kwale.
4. Daidaitawa: Fa'idar kashi 20%
Gyaran jiki shine mafi kyawun abin da za a iya sarrafawa don inganta PDI. Manufar ita ce a cimma daidaiton zafi da danshi wanda ke kunna gelatinization na sitaci da kuma plasticization na furotin kafin kayan su shiga cikin mayafin.
Mafi kyawun Sigogi na Kwandishan:
Nau'in Ciyarwa: Abincin kaji (masara da waken soya). Danshi: 15–17%. Zafin jiki: 80–85°C. Lokacin Rikewa: 30–60 daƙiƙa.
Nau'in Ciyarwa: Ciyar da Layer. Danshi Abin da ake nufi: 15–16%. Zafin jiki Manufar: 75–80°C. Lokacin Rikewa: 30–45 daƙiƙa.
Nau'in Ciyarwa: Abincin Alade. Danshi. Manufar: 15–17%. Zafin jiki Manufar: 75–85°C. Lokacin Rikewa: 45–90 daƙiƙa.
Nau'in Ciyarwa: Abincin shanu (mai yawan zare). Danshi. Manufar: 14–16%. Zafin jiki. Manufar: 70–80°C. Lokacin Rikewa: daƙiƙa 60–120.
Nau'in Ciyarwa: Abincin Ruwa. Danshi. Manufar: 16–18%. Zafin Jiki: 85–95°C. Lokacin Rikewa: 90–180 daƙiƙa.
Tsawon lokacin riƙewa yana inganta daidaiton yanayin sanyaya. Na'urorin sanyaya shaft biyu ko na dogon lokaci waɗanda ke faɗaɗa riƙewa zuwa daƙiƙa 90-180 suna da matuƙar amfani ga PDI, musamman ga abincin ruwa inda daidaiton ruwa yake da mahimmanci.
Ingancin Tururi. Tururi mai cikewa (ba tururi mai danshi wanda ke ƙara danshi mai yawa ba, ko tururin da ke zafi sosai wanda bai iya canja wurin zafi mai kyau ba) yana da mahimmanci. Tururin da ke danshi yana ƙara gogayya a ramukan da ke mutuwa kuma yana iya rage PDI; tururin da ke da zafi sosai yana danne tururin.
5. Nika: Fa'idar kashi 20%
Rarraba girman barbashi yana shafar ingancin pellet ta hanyoyi guda biyu: yankin saman da ake da shi don ɗaure sitaci-protein da kuma yawan tattara barbashi a cikin ramin da aka mutu.
Girman Barbashi Mafi Kyau. Ga yawancin abincin kaji, matsakaicin diamita na barbashi na microns 600-800 yana ba da mafi kyawun daidaito na aikin PDI da aikin dabbobi. Niƙa mai kyau yana ƙara girman saman da ake da shi don ɗaurewa amma yana ƙara farashin kuzarin niƙa. Niƙa mai ƙarfi yana rage ƙarfin ɗaurewa.
Daidaito. Rarraba girman barbashi mai kunkuntar ya fi muhimmanci fiye da takamaiman girman da aka nufa. Rarraba mai faɗi yana samar da ƙananan ƙwayoyin cuta masu yawan ciki mai canzawa, yana haifar da rauni waɗanda ke rage PDI.
6. Ma'aunin Zobe: Ma'aunin 15%
Ma'aunin zobe yana shafar PDI ta hanyar sigogi uku:
Rabon Matsi. Babban rabon matsi yana samar da ƙananan ƙwayoyin cuta masu tauri tare da ingantaccen PDI—har zuwa wani matsayi. Bayanan gwaji kan abincin masara da waken soya sun nuna cewa taurin ƙwayoyin cuta yana ƙaruwa daga 85N a 1:5 zuwa 170N a 1:8, tare da raguwar ƙimar tarar da ta dace daga 12.3% zuwa 4.8% [2]. Duk da haka, bayan 1:7, ƙimar tauri tana raguwa yayin da fitarwa ta ragu. Dole ne a daidaita rabon matsi mafi kyau na PDI da buƙatun fitarwa.
Yanayin Ramin Mutuwa. Ramin mutuwa da ya lalace—wanda aka faɗaɗa kuma ya yi ƙarfi saboda lalacewar da aka yi masa—yana samar da ƙananan ƙwayoyin cuta tare da ƙarancin PDI saboda ingantaccen rabon matsi yana raguwa kuma matsin lamba na fitarwa ya zama mara daidaituwa. Bincike kan abincin gasasshen nama ya gano cewa yanayin mutuwa (sabo ko an sake gyara shi) ya shafi sinadarin ƙwayoyin cuta da crumble a masana'antar abinci ta kasuwanci [3].
Tsarin Ramin Die. Shigar da ramukan da aka toshe suna inganta kwararar kayan cikin na'urar, suna rage matsewa kafin a fara amfani da ita da kuma haɓaka samuwar pellet iri ɗaya. Tsarin ramuka madaidaiciya tare da isasshen fitarwa (zurfin nutsewa daga na'urar 2-3 mm) sune daidaitattun aikace-aikacen ciyarwa.
7. Nazarin Shari'a: Inganta PDI na Kazakhstan
Binciken shari'ar Hongyang Kazakhstan ya ba da tabbacin gaske game da waɗannan ƙa'idodi. Injin ya maye gurbin injin niƙa mai tsufa (shigar da shi a shekarar 2012, rayuwar zobe ta ragu zuwa awanni 600) da sabon sashin jerin Hongyang SZLH. Manyan shawarwarin tsari sun haɗa da:
