２．２自動化集中供粉系統(tǒng) 各個系統(tǒng)的優(yōu)勢說明２．２．１ 面粉接收系統(tǒng)
散裝自卸車采用簡單的機械和氣力輸送，具有結構簡單、配置靈活、設備數(shù)量少，占地空間小、投資省、維護方便、去向靈活等優(yōu)點，適用于周邊大、中型
食品廠的供粉自動化集中供粉系統(tǒng)食品加工業(yè)已經(jīng)開始淘汰傳統(tǒng)的手工模式，正朝著健康、 營養(yǎng)、專業(yè)、方便快捷的自動化方向發(fā)展，自動化供粉系統(tǒng)的應用可以將人們從繁重的工作中解脫出來。自動化供粉系統(tǒng)就是通過先進的ＰＬＣ系統(tǒng)控制機械設備運行，以實現(xiàn)用*少的人員成本將面粉**、準確、穩(wěn)定、高效的運送至各個工作點。隨著社會的進步，人民的生活逐漸朝方便快捷的方向發(fā)展，越來越多的人不愿意花費大量的時間在廚房，新一代的消費群體不斷增加，人們對方便食品的需求會越來越大， 方便食品類的加工廠應運而生，如掛面、方便面、饅頭、包子、面條、水餃、鍋貼、餡餅、披薩、春卷、油條、麻花、燒餅、烙餅、面包、餅干、炒面、油茶等等，這些現(xiàn)代化的食品加工企業(yè)均以面粉為加工原料，足以說明供粉系統(tǒng)在食品行業(yè)的重要性傳統(tǒng)供粉系統(tǒng)現(xiàn)狀傳統(tǒng)的供粉系統(tǒng)采用的人工供粉，而且原料均為袋裝面粉，供粉量都是根據(jù)一定單位時間內投入面粉的袋數(shù)計量。

此自動化集中供粉系統(tǒng)在食品加工行業(yè)持續(xù)相當長的一段時間，但是隨著商品經(jīng)濟的發(fā)展，人們工作效率、生活水平的提高，健康生活的飲食的概念已經(jīng)的深入人心，此供粉方式終將被行業(yè)所淘汰。傳統(tǒng)的供粉方式存在以下弊端。１．１ 人工成本太高隨著社會的發(fā)展，**傳統(tǒng)的低勞動力成本優(yōu)勢已經(jīng)慢慢減弱，在傳統(tǒng)的生產(chǎn)過程中面粉原料的反復裝卸、搬運及投放都增加了勞動強度，必然會導致人工成本的不斷增長，而且人們對工作環(huán)境的要求越來越高。傳統(tǒng)的投料方式必然會產(chǎn)生大量的粉塵既危害勞動者的身體健康，又存在很大的**生產(chǎn)隱患。人工成本的增加必然提高食品加工的成本，降低市場競爭力，直接影響企業(yè)的效益

材料成本太高傳統(tǒng)的加工企業(yè)采用的原料均為２５ ｋｇ的面粉小包裝，假如加工廠１ ｄ使用面粉量為３０ ｔ，則每天需要１ ２００個面粉包裝袋，每個包裝袋的成本按照平均１元／個計算，則每天包材的支出成本為１ ２００元。對于部分自有面粉加工廠的食品企業(yè)來說，短距離的包裝運輸無疑是一種浪費和損耗。１．３ 食品**難以控制隨著《食品**法》的推出，人們對食品**越來越重視，在傳統(tǒng)的供粉工藝中，人工投料過程中工作環(huán)境是開放式的，面粉直接與外界接觸，難免在搬運及拆袋過程中造成二次污染，面粉質量難以控制。１．４ 食品質量難以控制傳統(tǒng)的人工供粉以面粉袋數(shù)作為依據(jù)，與實際重量存在一定的誤差，很難保證食品的質量的可靠與穩(wěn)定。２ 自動化集中供粉系統(tǒng)的應用與傳統(tǒng)供粉系統(tǒng)相比，

兩個面粉倉可存放不同的品種，根據(jù)生產(chǎn)需要，通過調節(jié)變頻喂料絞龍的頻率，已達到面粉粗配的目的，可保證面粉質量的穩(wěn)定，使生產(chǎn)更加靈活、方便、可操作性強。２．２．３
 面粉篩理系統(tǒng)
面粉在進入生產(chǎn)車間之前必須經(jīng)過篩理，以防止面粉結塊、生蟲污染食品原料，也可防止在人工拆袋過程中繩頭等異物掉入。磁選系統(tǒng)可以篩選出面粉中的磁性物質，保證面粉品質和食品**。２．２．４ 面粉輸送系統(tǒng)
物料輸送的管道化、密閉化和自動化，是現(xiàn)在散狀物料輸送技術的發(fā)展方向，而氣力輸送無疑是實
現(xiàn)這種物流技術的*佳方式之一［

。自動化集中供粉系統(tǒng)面粉輸送采用氣力正壓輸送，與其他輸送裝置相比更**，有利于環(huán)境和衛(wèi)生，可避免物料受潮、混入異物，也可降低勞動強度，大大提高生產(chǎn)效率。２．２．５ 卸料系統(tǒng)

由于暫存?zhèn)}體積較小，壓運入倉后，直接吸風除塵，會產(chǎn)生大量的吸風粉，對生產(chǎn)造成不便，本系統(tǒng)采用專業(yè)的循環(huán)分離倉，可有效的減少吸風粉的產(chǎn)生，
減少人工成本及原料的浪費，提高經(jīng)濟效益。２．２．６ 稱量系統(tǒng)
本系統(tǒng)采用高精度型稱重模塊，結合稱重控制儀表對物料進行**稱量，在整個ＰＬＣ系統(tǒng)的控制下，準確、穩(wěn)定的為用粉點提供原料，大大提高了工作效率。配料秤量計算準確，全無人自動化操作同時使生產(chǎn)率提高，為企業(yè)帶來了可觀的經(jīng)濟效益和良好的社會效益，同時該系統(tǒng)中ＰＬＣ控制充分發(fā)揮了其抗干擾能力強、配置靈活、控制可靠、編程方便、易于維護和可現(xiàn)場調試的優(yōu)點，給整個系統(tǒng)的穩(wěn)定
性帶來較大的益處［
３］
。２．２．７ 除塵系統(tǒng)
在人工投料斗、壓運關風器、配料秤等易產(chǎn)生粉塵的作業(yè)點均設置了吸風點，并經(jīng)過布袋除塵器后排出室外，大大改善了工作環(huán)境，防止粉塵爆炸，保證生產(chǎn)**。
２．２．８ 控制系統(tǒng)
本系統(tǒng)是通過ＰＬＣ控制各個設備按照設計的流程穩(wěn)定運行，
并且在相應位置設置料位器等報警裝置，以達到在無人監(jiān)控的情況下，可保證設備的正常運行。配料秤的加料與放料也是通過ＰＬＣ控制來完成，整個系統(tǒng)大大減少了人工成本的投入，并且大大提高了生產(chǎn)效率和經(jīng)濟效益。在整個系統(tǒng)中，所有設備均設置現(xiàn)場檢修及急停開關，可以有效保證工作人員的人身**。

３ 結語自動化集中供粉系統(tǒng)是每個食品可供人類食用或飲用的物質，包括加工食品，半成品和未加工食品。   企業(yè)的重中之重，供粉環(huán)節(jié)的生產(chǎn)**是保證后續(xù)產(chǎn)品質量的關鍵。人工供粉系統(tǒng)主要靠人工作業(yè)方式投料，
人為因素大大降低了投料的精度及物料的**性，已遠遠不能滿足現(xiàn)代化食品企業(yè)的生產(chǎn)需要，
而自動化集中供粉系統(tǒng)在面粉接受、面粉出倉、面粉輸送、面粉稱量等環(huán)節(jié)均有很大優(yōu)勢，可以給企業(yè)帶來良好的經(jīng)濟效益，現(xiàn)已在多個大型食品企業(yè)得到應用。系統(tǒng)自動化供粉系統(tǒng)與人工供粉系統(tǒng)相比，具有運行穩(wěn)定、操作簡單、性價比高等特點，故是食品行業(yè)發(fā)展的必然趨勢采用的膜過濾器具有孔徑?。ǎ埃拨蹋恚?br> 、膜表面光滑、濾液通透阻力小、易于反沖和清洗、膜孔不宜
