Nekuenderera mberi kwekusimudzirwa kweindasitiri yezvekudya munyika, zvinodikanwa zvezviratidzi zvekudya pellet zviri kuwedzera, hazvisi izvo zvemukati zvinodiwa chete zvinofanirwa kuve zvakanaka (sekuita kwekudya kunovaka muviri, kudzivirira zvirwere, kuchengetedzwa kwenzvimbo yeindasitiri, nezvimwewo) , asiwo zvinodiwa zvehutano zvekunze zvinowedzera kuwedzera (zvakadai semuvara, kunhuhwirira, ukuru uye kureba kwemapellet ekudya, kurasikirwa kwemvura mumvura, nezvimwewo).Nekuda kwenzvimbo yekugara yemhuka dzemumvura, chikafu chinofananidzwa chinoda kugadzikana kwemvura kudzivirira kupararira nekukurumidza, kuparara uye kurasikirwa.Nokudaro, kugadzikana kwemvura yezvokudya zvemvura indekisi yakakosha kuti ive nechokwadi chehutano hwayo.Zvinhu zvinokanganisa kugadzikana kwekudya kwemvura mumvura ndezvizvi:
Chekutanga, saizi yepellet yezvinhu mbishi
Iyo pellet saizi yezvinhu zvakasvibirira inosarudza nzvimbo yepasi yekuumbwa kwekudya.Iyo yakatsetseka saizi yepellet, iyo yakakura nzvimbo yepasi, inosimba kugona kutora unyoro muutsi isati yaita granulating, iyo inobatsira pakudziya uye kuumbwa kwepellet, kuitira kuti chikafu chepellet chive nekugadzikana kwakanaka mumvura, uye zvakare inogona kurebesa nguva yekugara. muzvipfuyo zvemumvura, kunatsiridza kunyudza, uye kuderedza kusvibiswa kwemvura.General fish feed rew materials inofanira kupfuura nepa40 target standard sieve mushure mekukuya, 60 target standard sieve content ≤20%, uye shrimp feed rew materials inogona kupfuura 60 target standard sieve.
Chechipiri, chigayo chepellet chinofa
The compression reshiyo yemhete mold (inoshanda gomba kudzika / hole saizi) inewo imwe pesvedzero pakugadzikana kwechikafu chemvura mumvura.Iwo mapellet ekudya anogadzirwa nemhete mold kudzvanya neyakakura compression reshiyo ichave yakanyanya kuomarara, yakaomesesa chimiro uye yakareba kuramba mvura nguva.Yakajairika compression ratio yemvura mhete kufa ndeye 10-25, uye shrimp feed ndeye 20-35.
Chechitatu, kudzimwa uye kushatirwa
Chinangwa chekupisa ndeichi: 1. Nekuwedzera mhepo yekunyorovesa zvinhu, yakawanda yepurasitiki, inobatsira kune extrusion kuumba, kuitira kuti uvandudze kugona kwepellet yemuchina wepellet;2. Kuburikidza nekuita kwehydrothermal, starch muzvokudya inogona kuve yakazara gelatinized, mapuroteni anogona kuchinjwa, uye starch inogona kuchinjwa kuva makhahydrates akanyunguduka kuti avandudze kudya uye kushandiswa kwechiredzo;3. Kuvandudza kuwanda kwepellets, kutaridzika kwakanaka, kwete nyore kuderedzwa nemvura, kuwedzera kugadzikana mumvura;4. Mhedzisiro yepamusoro yekushisa kwemaitiro ekupisa inogona kuuraya mabhakitiriya anokuvadza akadai seEscherichia coli uye Salmonella mukudya, kuvandudza kushanda kwekuchengetedza uye kunobatsira kune hutano hwezvipfuyo zvemvura.
Ina, inonamira
Adhesives akakosha ekuwedzera ayo anoita basa rekubatanidza uye kuumba mumvura yekudya, iyo inogona kukamurwa kuita zvinhu zvakasikwa uye makemikari ekugadzira zvinhu.Iyo yekare inogona kugoverwa kuva shuga (starch, gorosi, chibage chekudya, nezvimwewo) uye mhuka yemhuka (pfupa glue, ganda guru, hove pulp, nezvimwewo);Chemical synthetic substances is carboxymethyl cellulose, sodium polyacrylate, etc. Mukugadzira chikafu chehove, huwandu hwakakodzera hwebinder hunowedzerwa kuvandudza kugadzikana kwekudya mumvura.
