摘要:本文分析了原料粒度對(duì)消化率、營(yíng)養(yǎng)平衡、顆粒質(zhì)量等的影響，提出水產(chǎn)飼料    的粒度要求；建議通過(guò)粉碎設(shè)備的正確選用、粉碎作業(yè)的合理安排及規(guī)范粒度檢測(cè)制度等措施來(lái)保證水產(chǎn)飼料的粒度質(zhì)量。

1. 粒度對(duì)消化率的影響<o:p></o:p>
1.1 粒度與消化率
飼料被水產(chǎn)動(dòng)物食入后，在齒嚼、腸胃蠕動(dòng)等機(jī)械力作用下破碎并和消化液攪拌混合。消化液浸潤(rùn)并水解飼料，使其中的蛋白質(zhì)、淀粉、脂肪等大分子營(yíng)養(yǎng)物質(zhì)成為可吸收利用的小分子。
飼料被消化,首先得和消化液接觸。增加飼料粒子的表面積，就增加了飼料和消化液的直接接觸面積，同時(shí)也加快了消化液滲透到飼料粒子內(nèi)部的速度。飼料粒子表面積不容易直接測(cè)得，但可由以下公式計(jì)算飼料粒子總表面積：
<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><v:imagedata o:title="" src="file:///C:/DOCUME~1/work_1/LOCALS~1/Temp/msoclip1/01/clip_image001.wmz"></v:imagedata> 
式中：At：粉料粒子總表面積（cm2）<o:p></o:p>
      φS：表面積形狀系數(shù)，球形φS=π<o:p></o:p>
      w：總質(zhì)量（g）<o:p></o:p>

飼料粉碎越細(xì)，粒度越小，表面積越大，和消化液接觸面越大，消化液浸透飼料所需的時(shí)間就越短。蝦和部分魚(yú)的消化道很短，更有必要增加粒子表面積，以縮短飼料消化所需的時(shí)間，提高飼料消化率。
1.2 水產(chǎn)飼料原料粒度標(biāo)準(zhǔn)
各種水產(chǎn)動(dòng)物及不同生長(zhǎng)期的同種水產(chǎn)動(dòng)物對(duì)飼料的粉碎粒度要求不同。在我國(guó)2003年前的水產(chǎn)行業(yè)標(biāo)準(zhǔn)中對(duì)此提出的指標(biāo)如表1。

以撞擊力為主的固體粉碎機(jī)極少能將飼料粉碎到粒徑小于50μm。根據(jù)表4-1-6的要求，必須采用特殊的方法進(jìn)行微囊飼料的原料粉碎。膠體磨等用于食品、制藥、化工等行業(yè)的濕料粉碎設(shè)備成為制作微囊飼料的必備工具。但要得到粒度小于10μm的粉碎物，在目前仍是微囊飼料加工中的一項(xiàng)技術(shù)難點(diǎn)。對(duì)某些組份選用可溶性原料。溶解后，使其以分子狀態(tài)混入其它組分，從而提高均勻分布性。
用于飼料粒度檢測(cè)的標(biāo)準(zhǔn)篩，篩孔尺寸不小于45μm。當(dāng)篩孔尺寸小于45μm時(shí)，篩理過(guò)程極難正常進(jìn)行。對(duì)于微囊飼料原料的粒度測(cè)定應(yīng)采用顯微鏡法、氣流分級(jí)法等進(jìn)行。
3. 粒度對(duì)制粒質(zhì)量的影響<o:p></o:p>
3.1．粒度與調(diào)質(zhì)
水產(chǎn)飼料加工中的調(diào)質(zhì)是對(duì)原料的水熱處理過(guò)程。當(dāng)蒸汽與飼料原料接觸時(shí)，熱量和水分同時(shí)作用于各個(gè)粉粒的表面并向粉粒內(nèi)部傳遞。熱量的傳遞依靠粉粒內(nèi)部分子振動(dòng)按溫度梯度從表及里快速進(jìn)行。而水分的傳遞則通過(guò)粉粒中存在的毛細(xì)管慢慢向內(nèi)滲透。圖1中的兩條曲線，一條表示粉粒周邊由水包裹時(shí)，粉粒中心水分由12%達(dá)到30%所需的時(shí)間；另一條曲線為粉粒周邊溫度為95℃時(shí)，粒心溫度由室溫達(dá)到90℃所需的時(shí)間。

<IMG height=228 src="http://www.cnm51.com/images/News/20060531_hglfnaub.gif" width=325 border=0>
圖1的試驗(yàn)結(jié)果反映出，熱量的傳遞速度遠(yuǎn)遠(yuǎn)快于水份的傳遞速度。既然調(diào)質(zhì)是對(duì)物料的水熱處理，只有在水分和熱量同時(shí)作用于物料時(shí)才會(huì)達(dá)到應(yīng)有的效果。水分傳遞所需時(shí)間長(zhǎng)將影響調(diào)質(zhì)中的水熱處理效果。只有減短水分完全濕潤(rùn)粉粒所需的時(shí)間，才能增加水分和熱量共同作用于全部飼料的時(shí)間。
粉粒的粒度減小，可增加水分進(jìn)入粒子內(nèi)部的通道和減小水分達(dá)到粒心的距離，是縮短滲透所需時(shí)間的有效措施。因而在一定范圍內(nèi)減小原料粒度是提高調(diào)質(zhì)效果的常用手段。
從單個(gè)粉粒來(lái)看，粒子越小，被蒸汽完全濕潤(rùn)所需時(shí)間越短。但在水產(chǎn)飼料生產(chǎn)中，并非所有徑微粉碎的物料都能在很短的時(shí)間內(nèi)達(dá)到理想的水分分布。隨著粒度的減小，飼料的流動(dòng)性變差，易于結(jié)團(tuán)。在蒸汽質(zhì)量遠(yuǎn)低于粉粒質(zhì)量的調(diào)質(zhì)條件下，常形成內(nèi)干外濕的料團(tuán)。一些實(shí)驗(yàn)中出現(xiàn)粉碎越細(xì)，調(diào)質(zhì)效果越差的結(jié)果，粉料結(jié)團(tuán)可能是主要原因。改良調(diào)質(zhì)器的蒸汽進(jìn)入方式、增大槳板轉(zhuǎn)速及調(diào)整槳板偏角等措施，能在某種程度上減小細(xì)粉物料團(tuán)的直徑。
圖1 顯示的水分傳遞時(shí)間曲線與二次方程曲線相吻合，即濕潤(rùn)粒心所需的時(shí)間隨粒徑的二次方增加。當(dāng)粉粒粒徑較大時(shí)，其增量很可觀，但在粉粒粒徑很小的情況下，再減小粒徑，濕潤(rùn)粒心所需時(shí)間的絕對(duì)量減少就意義不大了。所以，實(shí)際生產(chǎn)中反映出，在粒徑的一定范圍內(nèi)，調(diào)質(zhì)效果最為理想。
3.2．粒度與耐水性
硬顆粒壓制中，在壓輥、壓模作用下，飼料穿越?？壮尚投?。各粉粒過(guò)孔期間的變形、貼緊、粘合等物理變化進(jìn)行的程度與粒子大小有關(guān)。原料粒度大，則難以軟化，可塑性差；粒子間接觸面積小，易留下空隙；具粘結(jié)力的物料不易分布均勻，不具粘結(jié)力的物料更易于脫落。這些特性使粒度大的原料難以制得耐水性好的硬顆粒水產(chǎn)飼料。采用不同加工工藝進(jìn)行同一配方的水產(chǎn)硬顆粒飼料生產(chǎn)，產(chǎn)品耐水性狀況如表3所示。

制粒前不管是否調(diào)質(zhì)，原料微粉碎都有益于提高產(chǎn)品的耐水性。表3的結(jié)果也反映出，微粉碎和調(diào)質(zhì)對(duì)改良顆粒耐水性都有效。也僅當(dāng)這兩項(xiàng)操作合理配合時(shí)，產(chǎn)品耐水性才有保障。
3.3．粒度與顆粒表面 
硬顆粒水產(chǎn)飼料制造中，原料中的大粉粒在三個(gè)方面影響產(chǎn)品的表面質(zhì)量。在圓柱體顆粒飼料兩端，大粒子原料使切口不平?？油莸亩嗣娌粌H影響外觀，同時(shí)會(huì)增加顆粒飼料的含粉率；在成型過(guò)程中，大粒子與周邊其它物料受力不勻，使顆粒飼料中存在較大的內(nèi)應(yīng)力。在冷卻干燥、儲(chǔ)運(yùn)等操作中，內(nèi)應(yīng)力加大導(dǎo)致顆粒表面裂縫或是顆粒斷裂，影響顆粒大小的均一和表面的平整；各種原料的顏色不同。各種大粒子原料間的色差、大粒子與細(xì)粉末間的色差，在顆粒飼料表面留下不規(guī)則斑點(diǎn)，給人以不均勻的感覺(jué)。 
水產(chǎn)飼料原料中常含有糠麩、餅粕等粗纖維含量較高的原料。粗纖維含量高的物料不易軟化，不易變形，一旦出現(xiàn)在擠壓顆粒飼料表面，常使顆粒外觀凹凸毛糙；存在于顆粒表面的大粉粒，如與周邊物料的膨化度不一致就會(huì)引起表面的不平整；擠壓過(guò)程中未能達(dá)到熔融狀態(tài)的原料，對(duì)產(chǎn)品表面均一性都會(huì)有影響，其影響的程度和這些原料的粒徑相關(guān)。 
原料經(jīng)過(guò)適當(dāng)微粉碎后，在同等的調(diào)質(zhì)和擠壓條件下，一方面粒子的相對(duì)軟化和變形程度增加，擠壓過(guò)程中的機(jī)械力可消去部分棱角；另一方面粒子體積小，對(duì)產(chǎn)品表面不平整程度的影響也小。要制得表面光潔的擠壓飼料，原料微粉碎是有效措施之一。特別在采用孔徑小于2mm的模板生產(chǎn)擠壓飼料時(shí)，大粒徑的原料對(duì)飼料表面質(zhì)量的影響極為明顯。 
表面毛糙影響擠壓顆粒飼料的外觀，并會(huì)使含粉率有所增高。但尚未見(jiàn)因表面不光潔影響采食量或消化率等的報(bào)道。擠壓顆粒飼料的表面平整或光潔度對(duì)養(yǎng)殖效果有多大影響？如何對(duì)這些表面質(zhì)量提出既有利于加工，又無(wú)損于養(yǎng)殖的要求？這些問(wèn)題還有待于研究和討論。
4. 避免不合格粒度的措施 <o:p></o:p>
4.1．選用合適的粉碎設(shè)備
產(chǎn)品品種較少的水產(chǎn)飼料廠，如專(zhuān)一生產(chǎn)鰻魚(yú)、龜鱉飼料的生產(chǎn)廠家，或?qū)Ｒ簧a(chǎn)普通魚(yú)飼料的廠家，建廠時(shí)選定一臺(tái)粉碎機(jī)后，所有產(chǎn)品都由該粉碎機(jī)粉碎。在產(chǎn)品對(duì)粉碎粒度要求變化時(shí)，通過(guò)改換篩片或改變離心氣流分級(jí)器轉(zhuǎn)速等方法在小范圍內(nèi)進(jìn)行粒度調(diào)節(jié)。 
這類(lèi)廠家中，產(chǎn)品粒度是否合適，很大程度上決定于選用的粉碎機(jī)是否合適。不同類(lèi)型的粉碎設(shè)備適用于粉碎產(chǎn)品不同的粒度要求和不同的原料特性。采用立式微粉碎機(jī)粉碎普通成魚(yú)飼料，會(huì)因能耗，設(shè)備易損件等的費(fèi)用高而使加工成本大幅度增加。以普通有篩錘片粉碎機(jī)粉碎鰻魚(yú)或蝦飼料，勢(shì)必選用篩孔直徑極小的篩片。即使如此，產(chǎn)品粒度仍得不到保證，粉碎產(chǎn)量、電耗、篩片破損速度及料溫過(guò)高等會(huì)使生產(chǎn)廠家難以承受。 
粉碎設(shè)備在日常操作管理中也會(huì)引起粉碎產(chǎn)品粒度變化。同一臺(tái)粉碎機(jī)，經(jīng)一段時(shí)間工作后，與物料接觸的部件會(huì)磨損，錘擊件與固定的篩片或齒板的間隙將增大。即使其它加工參數(shù)都不變，間隙的增加就會(huì)明顯增大粉碎產(chǎn)品粒度。粉碎機(jī)篩片的非常規(guī)破損、離心氣流分級(jí)器轉(zhuǎn)速的自動(dòng)漂移或風(fēng)速波動(dòng)等也會(huì)是這類(lèi)廠家粉碎不當(dāng)?shù)脑颉?lt;BR>
另一類(lèi)水產(chǎn)飼料廠的產(chǎn)品品種多，普通魚(yú)飼料，蝦飼料及龜鱉飼料都生產(chǎn)。在一條生產(chǎn)線中配有兩種類(lèi)型不同的粉碎機(jī)。針對(duì)具體的原料和產(chǎn)品，有三種粉碎方案可選擇。當(dāng)原料和產(chǎn)品的粒度差較大時(shí)，兩種類(lèi)型粉碎設(shè)備串聯(lián)使用，即先粗粉碎，后微粉碎的二次粉碎方案，往往產(chǎn)量高，能耗低，產(chǎn)品粒度更有保障。 
即使采用了兩種類(lèi)型的粉碎機(jī)，由于產(chǎn)品的多樣性，對(duì)每一種類(lèi)的粉碎機(jī)都要求在較大的范圍內(nèi)變化產(chǎn)品粒度。如微粉碎機(jī)既用于生產(chǎn)蝦飼料，又用于生產(chǎn)鰻魚(yú)飼料。蝦飼料和鰻魚(yú)飼料的粒度要求就不一樣，加上蝦飼料中再分成蝦飼料、中蝦飼料和幼蝦飼料等，鰻魚(yú)飼料中分成鰻飼料，幼鰻飼料、黑仔鰻飼料及白仔鰻飼料等，希望從一臺(tái)微粉碎機(jī)中得到4-5種粒度規(guī)格不同的粉碎產(chǎn)物。 
這種類(lèi)型的廠家中，粉碎粒度變化范圍寬，加上生產(chǎn)品種變化頻率高，要求操作過(guò)程中應(yīng)用加工流程、篩孔尺寸、進(jìn)料量、風(fēng)量、轉(zhuǎn)速等多種調(diào)節(jié)手段來(lái)適應(yīng)粒度要求變化。并通過(guò)詳盡的操作記錄來(lái)量化設(shè)備操作要求，以求在產(chǎn)品品種變換時(shí)，及時(shí)設(shè)定合適的參數(shù)。 
4.2．免粉碎原料的正確選擇
水產(chǎn)飼料生產(chǎn)中，部分原料不經(jīng)粉碎直接與其它粉碎后的原料混合。部分原料免粉碎的目的或是為了減少粉碎能耗、提高產(chǎn)量，或是為了使某些原料免于粉碎過(guò)程中遭受破壞。 
　　何種原料可決定為免粉碎原料，首先看其粉碎過(guò)程中的破壞程度，而后看其粒度。有多種維生素在粉碎時(shí)和粉碎后生理效價(jià)大幅下降。在選購(gòu)維生素原料時(shí)盡量取細(xì)粉末狀的產(chǎn)品。某些水溶性原料，如B屬維生素等，只要具有足夠的粒子數(shù)在飼料中能分布均勻，雖粒徑較大，但在粉末飼料中并不影響飼料的營(yíng)養(yǎng)價(jià)值。粉末飼料飼喂前的加水?dāng)嚢枋惯@些可溶性原料成為溶液后附著于其它物料上，粉末狀時(shí)的大粒在飼喂前已消失。 
　　將某些細(xì)粉末狀的蛋白源或能量源原料固定為免粉碎原料也易導(dǎo)致產(chǎn)品粒度不合格。原料的產(chǎn)地、生產(chǎn)廠家不同，同品種的原料粒度會(huì)有較大的不同。同一原料生產(chǎn)廠家在不同季節(jié)或不同參數(shù)下生產(chǎn)的原料，粒度也有差異。同類(lèi)飼料在飼喂對(duì)象的不同生長(zhǎng)期，要求有不同的飼料粉碎粒度。應(yīng)對(duì)這些變化的方法是健全原料粒度檢測(cè)制度，按批對(duì)照產(chǎn)品粒度要求，而后決定免粉碎原料品種。 
　　礦物添加劑預(yù)混料通常粒度較細(xì)，但在水產(chǎn)飼料加工中不宜作為免粉碎原料。一則礦物添加劑預(yù)混料用量少，免粉碎對(duì)提高產(chǎn)量，降低電耗貢獻(xiàn)不大；二則礦物添加劑預(yù)混料易于成團(tuán)結(jié)塊。一旦團(tuán)塊狀的礦物添加劑進(jìn)入飼料成品，會(huì)對(duì)養(yǎng)殖動(dòng)物的健康形成較大的隱患。 
4.3．防止不同產(chǎn)品間的混雜
針對(duì)不同種類(lèi)的水產(chǎn)動(dòng)物或同類(lèi)水產(chǎn)動(dòng)物的不同生長(zhǎng)期，所要求的飼料粒度有很大的差異。在同一條飼料生產(chǎn)線上，前批飼料在設(shè)備中的殘留物會(huì)進(jìn)入后批生產(chǎn)的飼料中。當(dāng)換品種生產(chǎn)細(xì)小粒度的飼料產(chǎn)品時(shí)，前批飼料的大粒子原料將影響該批飼料的粒度質(zhì)量。防止因產(chǎn)品間混雜而引起的粒度質(zhì)量下降可從批次間清理、生產(chǎn)作業(yè)安排及設(shè)備和工藝路線調(diào)整三方面進(jìn)行。
生產(chǎn)過(guò)程中，更換成粉碎粒子更細(xì)的產(chǎn)品前，混合機(jī)、提升機(jī)、螺旋輸送機(jī)、調(diào)質(zhì)器及部分料倉(cāng)和溜管等有物料殘留的設(shè)備需進(jìn)行清理。清理按生產(chǎn)流程，自粉碎機(jī)后由前向后逐臺(tái)設(shè)備進(jìn)行。 
　　安排營(yíng)養(yǎng)要求和粒度要求相近的產(chǎn)品銜接生產(chǎn)，盡量避免由粉碎要求不高的產(chǎn)品直接轉(zhuǎn)換生產(chǎn)粉碎要求很高的產(chǎn)品。
有一定生產(chǎn)規(guī)模的水產(chǎn)飼料廠，不宜將普通魚(yú)飼料和蝦、蟹飼料，或粉狀飼料和粒狀飼料置于同一條生產(chǎn)線中。不同飼料在原料要求、粉碎粒度要求、營(yíng)養(yǎng)要求等方面差異較大。在同一條生產(chǎn)線中生產(chǎn)不同種類(lèi)的水產(chǎn)飼料，為防止混雜而需要的清理工作量會(huì)很大，并由此降低生產(chǎn)能力，增加單位質(zhì)量產(chǎn)品的生產(chǎn)成本。在設(shè)備投資富裕的工廠，采用帶自清裝置的自清式混合機(jī)、自清式斗式提升機(jī)等，能較大程度地減少互混引起的產(chǎn)品質(zhì)量下降。 
4.4. 規(guī)范粒度檢測(cè)制度
粉碎粒度是水產(chǎn)飼料的重要加工質(zhì)量指標(biāo)之一。規(guī)范化的檢測(cè)，是這一質(zhì)量指標(biāo)的必要保證措施。
在水產(chǎn)飼料生產(chǎn)線安裝時(shí)，就有必要在粉碎后及調(diào)質(zhì)前各設(shè)置一個(gè)取樣口。通過(guò)前一個(gè)取樣口獲取粉碎物或分級(jí)后的粉碎物樣品。該樣品的粒度可反映出粉碎機(jī)的工作狀況。篩板孔徑是否合適，篩板有無(wú)破損，分級(jí)器調(diào)節(jié)是否合理及齒板和錘擊件的磨損等都可引起該樣品的粒度變化。調(diào)質(zhì)前獲取樣品，粉狀飼料生產(chǎn)則在成品打包前獲取樣品。所有對(duì)粒度有影響的因素都會(huì)引起該樣品的粒度變化。如粉碎后樣品的粒度合格，則引起最終產(chǎn)品粒度不合格的原因可著重在免粉碎原料和混雜兩方面尋找。
粒度檢測(cè)分化驗(yàn)員檢測(cè)和操作工檢測(cè)兩級(jí)進(jìn)行?；?yàn)員對(duì)每一個(gè)生產(chǎn)品種在調(diào)質(zhì)前或成品處取樣化驗(yàn)。按行業(yè)標(biāo)準(zhǔn)或企業(yè)標(biāo)準(zhǔn)進(jìn)行粒度測(cè)定，由測(cè)定數(shù)據(jù)得出粒度是否合格的結(jié)論。操作工則需在每一個(gè)品種生產(chǎn)的開(kāi)始，中間和將結(jié)束時(shí)三次檢測(cè)粉碎后的物料粒度。并在每一品種開(kāi)始生產(chǎn)時(shí)檢測(cè)調(diào)質(zhì)前的物料粒度。操作工檢測(cè)為粗檢測(cè)，按產(chǎn)品要求選用一個(gè)檢查篩，該檢查篩篩孔尺寸與產(chǎn)品的最大允許粉碎粒徑相當(dāng)。當(dāng)檢查篩上發(fā)現(xiàn)有較多篩上物時(shí)則需對(duì)粉碎機(jī)、分級(jí)器等與產(chǎn)品粒度有關(guān)的設(shè)備進(jìn)行細(xì)致檢查，找出大粉粒的產(chǎn)生原因并及時(shí)進(jìn)行必要的調(diào)整。開(kāi)始生產(chǎn)某批飼料時(shí)，在混合工序后對(duì)中間產(chǎn)品的粒度進(jìn)行檢測(cè)。根據(jù)檢測(cè)結(jié)果判定免粉碎原料合適與否。
