Michina yekuisa chisimbiso chetray yakagadziriswa (MAP): Kutsiva Gas-Flush (G) vs Kutsiva Vacuum-Flush (V)

Zvivharo zvemazuva ano zveMAP tray zvinogona kuisa zvakananga musanganiswa wegesi inochengetedza ("air-flush") mutireyi kana kutanga zvaburitsa mweya wozozadza. Zvivharo zvedu zveWenzhou Dajiang (DJPACK) tray zvinoratidza zvakajeka sarudzo iyi: mamodheru anogumira naG ndiwomichina yekukwesha gasi, nepo avo vanogumira muna V varimichina yekukwesha vacuum. MAP (Modified Atmosphere Packaging) michina inozadza matireyi nemusanganiswa wegasi unodzorwa (kazhinji N₂, CO₂, O₂) kuchengetedza chikafu. Nekutsiva mhepo yakajairika nenzvimbo isina gasi, MAP inowedzera nguva yekushanda uye inochengetedza ruvara, kunaka uye magadzirirwo.

Zvivhariso zvematray zvinogona kubata midziyo yakasiyana-siyana (matray, makapu, ndiro) uye kuisa zvekudya zvitsva (nyama, zvirimwa, masaradhi, chikafu chakagadzirwa, nezvimwewo) zvisati zvavhara firimu. Semuenzaniso, DJL-370G (gas-flush) uye DJL-370V (vacuum-flush) zvakafanana zvivhariso zvematray kunze kwenzira yazvo yekukwesha. Muzvikamu zviri pazasi, tinotsanangura mashandiro anoita nzira yega yega yekukwesha, mashandisirwo ayo, uye mabhenefiti eimwe neimwe.

Kurongedza Kushambadza Kwemhepo (Air-Flush)

In kukwesha gasikurongedza, muchinainopinza zvakananga musanganiswa wegesi unodzivirira mutireyi kuti ibvise mhepousati wavhara. Mukuita, gasi risina simba rinoiswa mupakeji, richisundira mhepo yese kunze. Kana gasi reMAP rikapinzwa nekumanikidzwa kwakanyanya—kune simba rakapetwa kashanu kusvika katanhatu kupfuura mweya uri mukati metireyi—rinosvina mweya kubva muchirongo woutsiva negasi rinodzivirira. Tireyi inobva yavharwa nemhepo itsva iri mukati. Hapana nhanho ye vacuum inoshandiswa - tireyi inoramba iri padanho remhepo kana kuti pedyo nekumanikidzwa panguva yese yekuvhara.

Nzira iyi ndiyonekukurumidzapane kutsiva chimbuzi ne vacuum flush. Semuenzaniso,yedumhando yemhando yepasiDJL-370GSealer (yekuputira gas-flush) inogona kumhanya ma cycles angangoita 5-6/min mudzidziso, nekukurumidza zvakanyanya kupfuura ma cycles 3-4/min emodhi ye vacuum.Michina yekukwesha gasishandisawo nzira iri nyore (isina imba inorema ye vacuum kana pombi hombe), saka inoshandisa simba shoma uye inoreruka. (Chokwadi ndechekuti,DJL-370Ginorema 170 kg chete kana 265 kgDJL-370V, uye simba re2.4 kW vs 3.5 kW.) Izvi zvinoshandura mitengo yemidziyo yakaderera uye mutengo wekushandisa.

Zvakanakira zveMAP yekukwesha gas-flush zvinosanganisira:

1.Yakanakira zvigadzirwa zvisingade okisijeni yakaderera zvakanyanya:

Kunyanya nyama tsvuku dzakadai senyama yemombe, yegwayana, uye zvigadzirwa zvenhengo, izvo zvinoda mwero wakati weokisijeni mukati metireyi kuti dzirambe dzine ruvara rwakajeka uye chitarisiko chitsva.

2.Kushanda zvakanaka kwakanyanya:

Sisitimu iyi inobvisa danho refu rekupomba vacuum, zvichikonzera nguva pfupi yekutenderera uye kubuda kwepamusoro zvichienzaniswa nemamodheru ekutsiva vacuum.

3.Mutengo wemuchina wakaderera:

Sezvo pasina kamuri re vacuum kana pombi ye vacuum inodiwa, kuvaka kwacho kuri nyore uye kunodhura zvishoma, zvichideredza mari yekugadzira nekugadzirisa.

4.Kushandiswa kwesimba kwakaderera:

Michina yekukwesha gasi inowanzoda simba shoma remagetsi uye inogona kushanda pamagetsi akajairwa echikamu chimwe chete.

5.Kushanda zvakanaka kwekuchinjana magasi:

Maitiro ekukwesha gasi anogona kuwana mwero wekutsiva gasi unopfuura 99%, zvichiita kuti MAP ishande zvakanaka kune zvigadzirwa zvakasiyana-siyana.

Kurongedza kweVacuum Flush (Kutsiva Vacuum)

In kukwesha-kupukutaKurongedza, muchina unotanga wagadzira vacuum wozozadza negasi. Kunyanya, pombi yekuputira yemukamuri inobvisa mhepo yese kubva mutireyi yakavharwa. Kana vacuum yakasimba (pedyo nezero pressure) yasvika, sisitimu inopinza gasi rinodzivirira mukamuri netireyi. Pakupedzisira, tireyi inovharwa kana kumanikidzwa kwemukamuri kwagadziriswa.

Maitiro aya ane matanho maviri (vacuum then gas) anoita kuti pave neO₂ shoma yasara.- kazhinji≤0.5%. Munguva yekutora vacuum step, muchina unochengetedza kumanikidzwa kwakaenzana mukati metireyi nemukamuri, zvichiita kuti chigadzirwa chisakanganiswe nekusiyana kwekumanikidzwa. Mushure mekutora vacuum step, sisitimu inoisa musanganiswa weMAP gas mutireyi uye inoenderera mberi nekuvhara kupisa, ichipedzisa kutenderera kwese kwekurongedza.

Nekuti pombi inorema ye vacuum nekamuri rakavharirwa zvinodiwa,michina ye cleaner-MAPdzakakura, dzakarema uye dzakaoma kunzwisisa. Makamuri makuru ekuputira mvura anoda mapombi evacuum ane kumhanya kwakanyanya kwekupomba. Semuenzaniso, mumamodeli edu emhando yepasi, kugona kwepombi kunowedzera nehukuru hwemuchina. Modhi yakakura kwazvo, DJL-440V, ine pombi yevacuum ye100 m³/h. Magadzirirwo akagadzirwa anowanikwawo kana ukakumbira.

Zvichienderana nemutengo, mamodheru evacuum anoda mavharuvhu nemapombi anodhura, zvichiwedzera mutengo wemuchina. Zvisinei, vacuum-MAP inopa shanduko yepamusoro yegesi: bvunzo dzinoratidza kuti mhepo inosvika 99.5% inogona kubviswa.

Zvakanakira zveMAP yekukwesha gas-flush zvinosanganisira:

1.Mazinga eokisijeni akaderera zvakanyanya:

Masisitimu ekutsiva vacuum akanakira zvigadzirwa zvinoda kudzora zvakanyanya okisijeni yasara. Nekubvisa mhepo kutanga wozozadza nemusanganiswa weMAP gas, sisitimu inogona kuwana O₂ level yakaderera kupfuura masisitimu ekudzura gas. Izvi zvinobatsira zvikuru kune zvigadzirwa zvinonzwa zvakanyanya kuoxidation kana kukura kwehutachiona.

2.Kushandiswa kwegasi kwakaderera uye mutengo wekushandisa wese:

Kunyangwe zvakadaromichina yekukwesha gasi (G-type)Zvine mutengo wakaderera wemidziyo, masisitimu ekutsiva vacuum anogona kuderedza zvakanyanya mutengo wekushandisa nekushandisa gasi reMAP shoma.

Nemasisitimu ekukwesha gasi, gasi rinodzivirira rinofanira kuiswa muhuwandu hwakawanda kuti mweya uripo ubviswe mutireyi. Kuti ive nechokwadi chekuti mhepo iri kuyerera zvakakwana, gasi rekuwedzera rinodiwa nguva dzose, izvo zvinozokonzera marara.

Kusiyana neizvi, masisitimu ekutsiva vacuum anongoda gasi rakakwana kuti aenzane nekumanikidzwa kuri mukati metireyi mushure mechikamu chevacuum. Sezvo mhepo yakawanda yakatobviswa, gasi reMAP shoma rinodiwa kuti tireyi izadzwezve, zvichikonzera kushandiswa kwakaderera zvakanyanya.

Saka, vatengi vanowanzoongorora mutengo wemuchina uchienzaniswa nemutengo wegesi pavanosarudza pakati pemhando dzeG-type neV-type, vachisarudza sarudzo inopa kushanda kwenguva refu kusingadhuri zvakanyanya.

3.Inoshanda zvakanyanya kune zvishandiso zvinoda huwandu hwegasi hwakarurama kwazvo

Kune zvigadzirwa zvinoda okisijeni shoma yasara kana michina yakakura, kutsiva vacuum kunogona kushanda zvakanaka.

Nekuti masisitimu ekukwesha gasi anovimba nekuyerera kwegasi kwakananga kuti asundire mweya kunze, mamwe makona kana nzvimbo dzisina kurongeka dzetireyi zvinogona kuoma kuchenesa zvachose. Izvi zvinoita kuti zvive zvakaoma kusvika pahuwandu hwakaoma hwegasi kana kuti mazinga eokisijeni akaderera zvakanyanya.

Masisitimu ekutsiva vacuum haana muganho uyu. Sezvo mhepo ichibviswa zvachose isati yazadzwazve, musanganiswa wegasi reMAP unozadza tireyi zvakaenzana, zvichiita kuti pave nemhepo yakarurama uye inoenderana. Kazhinji, kutsiva vacuum kunowana chiyero chegasi chinodiwa nekukurumidza uye zvakakwana kupfuura nzira dzekutsvaira gasi.

Kupisa Kwegasi vs Kupisa Kwevacuum: Kuenzanisa

Mhedziso

Kusarudza pakati peGas Flush (“G” type) neVacuum Flush (“V” type) yemuchina wako weMAP wetray-type zvinoenderana nehunhu hwechigadzirwa chako, zvinokosheswa pakugadzira, uye kukoshesa mari.

• Kana chinhu chikuru kwauri kugadzira nekukurumidza uye uri kurongedza zvinhu zvisingade okisijeni yakasara yakaderera — zvakaita senyama tsvuku, zvinhu zve deli, kana zvigadzirwa zvine chitarisiko neruvara zvakakosha — modhi yeGas Flush (G) inowanzova sarudzo yakanakisisa. Inokupa nguva yekumhanya nekukurumidza, mutengo wakaderera wemidziyo.yezvigadzirwa zvako.
• Kune rumwe rutivi, kana chigadzirwa chako chichida okisijeni shoma yakasara, kana kuti uchida kuderedza kushandiswa kwegasi rinodzivirira, modhi yeVacuum Flush (V) inogona kupa mari yakawanda munguva refu. Pasinei nemutengo wakakwira wekutanga (vacuum pump, sealed chamber), kushandiswa kwayo kwegasi shoma uye kushanda kwayo zvakanyanya kunogona kuita kuti ive yakachipa kune mamwe mashandisirwo.

KuWenzhou Dajiang / DJPACK Machinery, matray sealers edu akagadzirirwa kutsigira mamodhi ese ari maviri — ingosarudza chivakashure "G" kana "V" paunosarudza modhi yako (semuenzaniso,DJL-440G or DJL-440V). Kuchinjika uku kunokutendera kuti uenzanise mutengo wemuchina, kumhanya kwekugadzira, kushandiswa kwemafuta, uye mhando yechigadzirwa kuti zvienderane nezvinodiwa nebhizinesi rako.
