Okukulukuta kw’omukka (vacuum leakage) kwe kusinga okulemererwa ebyuma ebikaza firiigi mu makolero. Kijja kuleeta ebizibu omuli okukozesa amasannyalaze amangi, enzirukanya y’okukala okumala ebbanga n’okugwa kw’ebintu. Static pressure‐hold test y’enkola esinga okukola obulungi ey’okukebera okukulukuta nga tonnasindikibwa n’okulawuna buli lunaku mu kifo ky’ekkolero, ekiyinza okwekenneenya omutindo gw’okukulukuta okutwalira awamu awatali bikozesebwa bya bbeeyi eby’enjawulo ebizuula okukulukuta.
Enkola y’okukola mu bujjuvu: oluvannyuma lw’okukuŋŋaanya mu bujjuvu oba okuddaabiriza oluvannyuma lw’ekibinja, ggalawo bulungi oluggi lw’ekisenge. Tandika ppampu za vacuum era osika ekisenge wansi okutuuka ku vacuum enkomerero. Oluvannyuma lw’okutuuka ku muwendo gwa vacuum ogwateekebwawo, ggalawo ppampu zonna eziwunyiriza era oggale vvaalu za vacuum okwawula mu bujjuvu yuniti za vacuum. Tandika obudde era owandiike omuwendo gwa puleesa‐okulinnya munda mu kisenge mu bbanga erigere.
Emisingi gy’okukkiriza gyawukana ku yuniti ez’obunene obw’enjawulo. General reference for food‐grade industrial industrial freeze dryers: wansi w’embeera y’ebbugumu ery’ekisenge, oluvannyuma lw’okwawula ekibinja ky’obuziba, okulinnya kwa puleesa Okutono oba okwenkana 15Pa mu ddakiika 30 kitegeeza okukola obulungi ennyo; 15‐40Pa pressure‐rise egwa mu bbanga erikkirizibwa; okulinnya kwa puleesa waggulu wa 40Pa kiraga okukulukuta okweyoleka era okukebera ebifo ebikulukuta kulina okukolebwa.
Essira lisse ku bifo ebikulukuta emirundi mingi: 1 chamber‐door silicone sealing strip ne sealing contact surface, kebera oba ebifunfugu, enkwagulo, okukaddiwa & enjatika; 2 gaskets za buli kiyungo kya flange; 3 ebiyungo bya payipu za vacuum; 4 empeta ezisiba eza vacuum valves; 5 eddirisa ery’okutunuulira n’emyalo gy’okussa sensa ku bbugwe w’ekisenge.
Amagezi: Tokola pressure‐hold test ku hot chamber amangu ddala nga production run. Linda okutuusa ng’ekisenge kinnyogoga mu bujjuvu okutuuka ku bbugumu erya bulijjo, kubanga okugaziwa n’okukonziba kw’ebbugumu bijja kukyusakyusa okusoma kwa puleesa. Weewale okugezesebwa wansi w’empewo ey’amaanyi oba enkyukakyuka ensongovu mu bbugumu eritaataaganya ebivudde mu kukebera.
Okugezesebwa okukwata puleesa kuyinza okusalawo oba okukulukuta okutwaliza awamu kuliwo, naye tekusobola kulaga kifo kituufu eky’okukulukuta. Singa ekiva mu kukwata puleesa kiremererwa, kwata enkola ya spray‐leak‐detection okuzuula ebifo ebitongole ebikulukuta. Ddamu okukola pressure‐hold test oluvannyuma lw’okuddaabiriza okukakasa omuwendo ogulina ebisaanyizo. Okulawuna buli kiseera okukwata puleesa kuyamba okuzuula obulabe obukusike obw’okukaddiwa obw’okusiba ebitundu nga bukyali era kuziyiza okumenya okw’amangu nga okufulumya.
