自動(dòng)化集中供粉系統(tǒng)在節(jié)約人員成本、材料成本、保證食品**食品質(zhì)量等方面具有**的優(yōu)勢(shì),下面就某食品企業(yè)供粉系統(tǒng)為例具體說明自動(dòng)化供粉系統(tǒng)工藝
面粉主要通過散裝自卸車運(yùn)輸,并用其自帶的壓運(yùn)系統(tǒng)將面粉壓送至面粉倉(cāng)。面粉通過振動(dòng)倉(cāng)底卸料器和變頻喂料絞龍根據(jù)生產(chǎn)需要將一定量的面粉運(yùn)送至單倉(cāng)篩,
經(jīng)過單倉(cāng)篩的篩理以保證原料的質(zhì)量,如有外來袋裝面粉,也可通過人工投料斗將面粉輸送至單倉(cāng)篩。面粉在經(jīng)過單倉(cāng)篩篩理和磁選器磁選后,經(jīng)過一套簡(jiǎn)單的壓運(yùn)系統(tǒng)將面粉輸送至循環(huán)分離倉(cāng)暫存,以備后續(xù)工段的使用。當(dāng)用粉點(diǎn)需要面粉時(shí),面粉通過振動(dòng)倉(cāng)底卸料器和變頻喂料絞龍輸送至配料秤,根據(jù)生產(chǎn)需要,準(zhǔn)確稱量,并將面粉通過喂料絞龍輸送至各個(gè)用粉點(diǎn)。整個(gè)系統(tǒng)中,在易產(chǎn)生粉塵的工作點(diǎn)均已設(shè)置除塵系統(tǒng),以保證人員**。
2.2自動(dòng)化集中供粉系統(tǒng) 各個(gè)系統(tǒng)的優(yōu)勢(shì)說明2.2.1 面粉接收系統(tǒng)
散裝自卸車采用簡(jiǎn)單的機(jī)械和氣力輸送,具有結(jié)構(gòu)簡(jiǎn)單、配置靈活、設(shè)備數(shù)量少,占地空間小、投資省、維護(hù)方便、去向靈活等優(yōu)點(diǎn),適用于周邊大、中型
食品廠的供粉自動(dòng)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(yíng)養(yǎng)、專業(yè)、方便快捷的自動(dòng)化方向發(fā)展,自動(dòng)化供粉系統(tǒng)的應(yīng)用可以將人們從繁重的工作中解脫出來。自動(dòng)化供粉系統(tǒng)就是通過先進(jìn)的PLC系統(tǒng)控制機(jī)械設(shè)備運(yùn)行,以實(shí)現(xiàn)用*少的人員成本將面粉**、準(zhǔn)確、穩(wěn)定、高效的運(yùn)送至各個(gè)工作點(diǎn)。隨著社會(huì)的進(jìn)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(fèi)大量的時(shí)間在廚房,新一代的消費(fèi)群體不斷增加,人們對(duì)方便食品的需求會(huì)越來越大, 方便食品類的加工廠應(yīng)運(yùn)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(shí)間內(nèi)投入面粉的袋數(shù)計(jì)量。

此自動(dòng)化集中供粉系統(tǒng)在食品加工行業(yè)持續(xù)相當(dāng)長(zhǎng)的一段時(shí)間,但是隨著商品經(jīng)濟(jì)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(huì)的發(fā)展,**傳統(tǒng)的低勞動(dòng)力成本優(yōu)勢(shì)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(fù)裝卸、搬運(yùn)及投放都增加了勞動(dòng)強(qiáng)度,必然會(huì)導(dǎo)致人工成本的不斷增長(zhǎng),而且人們對(duì)工作環(huán)境的要求越來越高。傳統(tǒng)的投料方式必然會(huì)產(chǎn)生大量的粉塵既危害勞動(dòng)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(chǎng)競(jìng)爭(zhēng)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(gè)面粉包裝袋,每個(gè)包裝袋的成本按照平均1元/個(gè)計(jì)算,則每天包材的支出成本為1 200元。對(duì)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(yùn)輸無疑是一種浪費(fèi)和損耗。1.3 食品**難以控制隨著《食品**法》的推出,人們對(duì)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(yùn)及拆袋過程中造成二次污染,面粉質(zhì)量難以控制。1.4 食品質(zhì)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(shí)際重量存在一定的誤差,很難保證食品的質(zhì)量的可靠與穩(wěn)定。2 自動(dòng)化集中供粉系統(tǒng)的應(yīng)用與傳統(tǒng)供粉系統(tǒng)相比,

 面粉篩理系統(tǒng)
面粉在進(jìn)入生產(chǎn)車間之前必須經(jīng)過篩理,以防止面粉結(jié)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(zhì),保證面粉品質(zhì)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(dòng)化,是現(xiàn)在散狀物料輸送技術(shù)的發(fā)展方向,而氣力輸送無疑是實(shí)
現(xiàn)這種物流技術(shù)的*佳方式之一[
2]
。自動(dòng)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(dòng)強(qiáng)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(yùn)入倉(cāng)后,直接吸風(fēng)除塵,會(huì)產(chǎn)生大量的吸風(fēng)粉,對(duì)生產(chǎn)造成不便,本系統(tǒng)采用專業(yè)的循環(huán)分離倉(cāng),可有效的減少吸風(fēng)粉的產(chǎn)生,
減少人工成本及原料的浪費(fèi),提高經(jīng)濟(jì)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(jié)合稱重控制儀表對(duì)物料進(jìn)行**稱量,在整個(gè)PLC系統(tǒng)的控制下,準(zhǔn)確、穩(wěn)定的為用粉點(diǎn)提供原料,大大提高了工作效率。配料秤量計(jì)算準(zhǔn)確,全無人自動(dòng)化操作同時(shí)使生產(chǎn)率提高,為企業(yè)帶來了可觀的經(jīng)濟(jì)效益和良好的社會(huì)效益,同時(shí)該系統(tǒng)中PLC控制充分發(fā)揮了其抗干擾能力強(qiáng)、配置靈活、控制可靠、編程方便、易于維護(hù)和可現(xiàn)場(chǎng)調(diào)試的優(yōu)點(diǎn),給整個(gè)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(yùn)關(guān)風(fēng)器、配料秤等易產(chǎn)生粉塵的作業(yè)點(diǎn)均設(shè)置了吸風(fēng)點(diǎn),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(gè)設(shè)備按照設(shè)計(jì)的流程穩(wěn)定運(yùn)行,
并且在相應(yīng)位置設(shè)置料位器等報(bào)警裝置,以達(dá)到在無人監(jiān)控的情況下,可保證設(shè)備的正常運(yùn)行。配料秤的加料與放料也是通過PLC控制來完成,整個(gè)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(jì)效益。在整個(gè)系統(tǒng)中,所有設(shè)備均設(shè)置現(xiàn)場(chǎng)檢修及急停開關(guān),可以有效保證工作人員的人身**。

3 結(jié)語自動(dòng)化集中供粉系統(tǒng)是每個(gè)食品可供人類食用或飲用的物質(zhì),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(zhì)量的關(guān)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(yuǎn)遠(yuǎn)不能滿足現(xiàn)代化食品企業(yè)的生產(chǎn)需要,
而自動(dòng)化集中供粉系統(tǒng)在面粉接受、面粉出倉(cāng)、面粉輸送、面粉稱量等環(huán)節(jié)均有很大優(yōu)勢(shì),可以給企業(yè)帶來良好的經(jīng)濟(jì)效益,現(xiàn)已在多個(gè)大型食品企業(yè)得到應(yīng)用。系統(tǒng)自動(dòng)化供粉系統(tǒng)與人工供粉系統(tǒng)相比,具有運(yùn)行穩(wěn)定、操作簡(jiǎn)單、性價(jià)比高等特點(diǎn),故是食品行業(yè)發(fā)展的必然趨勢(shì)采用的膜過濾器具有孔徑小(0.2μm)

Automated supply system is through the advanced PLC system to control the operation of machinery and equipment to achieve the minimum cost of personnel to flour safe, accurate, stable and efficient delivery to the various operating points. With the progress of society, the people's life gradually toward the direction of rapid development, more and more people do not want to spend a lot of time in the kitchen, a new generation of consumer groups continue to increase, people demand for convenience food will be more and more Large and convenient food processing plants such as noodles, instant noodles, steamed buns, buns, noodles, dumplings, fried dumplings, pies, pizza, spring rolls, fried dough sticks, twist, biscuits, pancakes, bread, biscuits, fried noodles And so on, these modern food processing enterprises are flour for the processing of raw materials, enough to explain the importance of the supply system in the food industry The traditional system of powder supply system The traditional supply of powder system for the use of artificial powder, and raw materials are bagged flour, The amount of powder is based on a certain amount of time into the flour of the number of bags.

This process of automatic centralized supply of powder in the food processing industry for a long period of time, but with the development of commodity economy, people work efficiency, improve the standard of living, the concept of healthy living diet has been deeply rooted in the people, Will be eliminated by the industry. The traditional way of supplying powder is the following malpractice. 1.1 Labor costs are too high With the development of society, China's traditional low labor cost advantage has been gradually weakened in the traditional production process of repeated processing of flour raw materials, handling and delivery have increased labor intensity, will inevitably lead to artificial The cost of the growing, and people on the working environment requirements are getting higher and higher. The traditional way of feeding is bound to produce a lot of dust not only endanger the health of workers, but also a lot of safety production hidden dangers. The increase in labor costs will inevitably increase the cost of food processing, reduce market competitiveness, a direct impact on business efficiency
Material costs are too high The traditional processing enterprises are using 25 kg of flour raw materials, if the processing plant 1 d use of flour for 30 t, then need 1 200 per day flour bags, the cost of each bag in accordance with the average 1 yuan / month calculation, the daily cost of packaging materials for the package of 1,200 yuan. For some of its own flour processing plant food companies, short-distance packaging and transportation is undoubtedly a waste and loss. 1.3 Food safety is difficult to control With the introduction of "Food Safety Law", people pay more and more attention to food safety, in the traditional powder supply process, the artificial feeding process of working environment is open, flour direct contact with the outside world , Inevitably in the handling and unpacking process caused by secondary pollution, flour quality is difficult to control. 1.4 food quality is difficult to control the traditional artificial powder to the number of flour bags as a basis, and the actual weight there is a certain error, it is difficult to ensure the quality and stability of food quality. 2 automatic centralized supply of powder system applications Compared with the traditional supply system,

The 2.2.7 Dust removal system
In the artificial hopper, pressure off the wind, batching scales and other easy to produce dust at the operating point are set up suction points, and after the bag filter discharged from the outdoor, greatly improving the working environment, to prevent dust explosion, to ensure production safety.
2.2.8 control system
The system is controlled by PLC equipment in accordance with the design process of stable operation,
And in the corresponding position to set the level device and other alarm devices, in order to achieve unsupervised circumstances, can guarantee the normal operation of equipment. The feeding and discharging of the batching is also carried out by PLC control. The whole system greatly reduces the input of labor cost, and greatly improves the production efficiency and economic efficiency. In the whole system, all the equipment are set on-site maintenance and emergency stop switch, can effectively ensure the safety of the staff.
3 Conclusion
Automated centralized supply systems are substances that are available for human consumption or consumption, including processed foods, semi-finished products and unprocessed food. The top priority of the enterprise, the supply chain for the production of safety is the key to ensure the quality of follow-up products. Artificial powder supply system mainly by manual operation feeding,
Human factors greatly reduce the accuracy of feeding and material safety, has been far from being able to meet the needs of modern food production enterprises,
The automatic centralized supply of powder system in the flour to accept, flour out of the warehouse, flour transport, flour weighing and other sectors have great advantages, can give enterprises a good economic benefits, is now in a number of large food enterprises have been applied.
