Hazvina mhosva kuti kunaka kwezvinhu zvakabikwa zvakadini, haugoni kuenzanisa mabheji akashandiswa nechinhu chero chipi zvacho! Vabiki vapeki vanopa mazano vasati vatanga kushandiswa kwekubheka mabhizimisi emiti, inofanira kupeta zvisikwa zvakasununguka (upfu, shuga yakasvibirira, kocoa) kuburikidza neupfu weefu. Sifted products haisi kungogadziriswa zviduku zviduku zvakadai semasaga uye zvipembenene, asi vanowanawo zvakaenzana, zvinokonzerwa neokisijeni uye zvinonyatsoyerwa. A sieve yekuchera furawa inokubvumira kuti uite hupfu hunotyisa, zvinoshamisa. Yakanga isiri yega yekuti mumazuva ekare echingwa, yakabikwa kubva muupfu hwakatsetseka, yainzi "sieve" uye yakanga inodhura kudarika "furry" chingwa, yakabikwa kubva muupfu hwakakwana.
Maswee akasiyana muhupamhi uye kukura kwemasero: maduku masero, kunyanya kuchenjerera chigadzirwa chikuru chinowanikwa. Uyewo upfu hwemazuva ano humwe hunosiyana mukuvakwa uye zvinhu kubva kwazviri.
Wood Sieve
Imwe nyuchi yemapuranga yeupfu ndiyo chigadziko chemagetsi. Iheeves yokutanga iyo yakanga iri rimiti yemapuranga ine grid yaive yakasungirirwa yefarasi, iyo yaiwanzonzi "sieve" muRussia. Zvishoma nezvishoma gira racho rakatsiviwa nesimbi yesimbi yakasungirirwa kubva pamatare akapfava, uye nekugadzirwa kwezvinhu zvakagadziriswa zvekugadzira mesh, tsvina dzenzou dzakatanga kushandiswa. Rimha inowanzoitwa yepurasitiki kana yesimbi. Kunyangwe vamwe vakadzi vemazuva ano vari kusarudza sieve dzemapuranga, vachifunga kuti midziyo yakadaro inowedzera kushamwaridzana.
Metal sieve
Mazuva ano masimbi eseves eupfu anogadzirwa kubva kumusoro kwepamusoro tsvina isina tsvina. Kuti zvive nyore, chigadzirwa chacho chinowanzogadziriswa nesabata rimwechete (se scoop) kana zvigadziro zviviri zvakaitwa zvepurasitiki kana epurasitiki.

Pamusana pekushandurwa kusina kushandiswa kwepasi, furasi inopfuura isinganonoki kuburikidza nemasero, sezvo mashizha anotsemura maruva, uye zvose zvisina kuchena zvekunze zvinoramba zviri mumambure. Kudzora kwegadziriro iri mumucheka we sieve. Paunenge uchifambisa kiyi, iyo michina yemagetsi esimbi, iyo shanduko inotenderera mumagetsi ekugadzirwa kweupfu, uye chigadzirwa chacho hachina kufanana. Chigadzirwa chacho chakashongedzwa nemabhandi maviri, anovimbisa kusimba, uye ane chiyero chekuyera.
Uniform sieving haibvumiri kudyara hupfu hwekubheka, asiwo kugovera zvidimbu zve nyama kana hove, uyewo kugovera poda kubva muhuga wehuga kana checoa pamusoro pezvipo , mafura, zvingwa nezvimwewo zvigadzirwa zvemabheka.
