The overflow device in the role of mould machine wash is wash the thing to be cleaned after mildewed (mycelia, conidium, stick dirt, sundry etc) in a short time, the machine turned the overflow from mouth to wash face in the position of mould slot and the level of the overflow of the space there is enough, can guarantee to be cleaned after washing mildew objects in the short time eduction cake layer.3.2 Belt spraying machine Main material thickness controller by conveyer belt, and the spray nozzle, spraying water recycling system and transmission system, etc.Belt spraying machines main function is already cleaning the material for further douchi song, and can according to song clean material humidity proper adjustment. Take right # will pepper cut into 3 4 cm, add the butter low-temperature extraction mention 1 h or so # join crushing prickly ash and saute until out MaWei # join alleviate pains powder, garlic, cubed scrambled to taste a # join with yellow rice wine dissolve of douchi # slightly fry # join LaoZao juice, sugar, monosodium glutamate, chicken essence and yeast extract # join ripe rapeseed oil fry 4 5 minutes # packaging , 30 min # 121 high temperature sterilizing # inspection # finished products.4.2 Operating points 4.2 .1The first to understand the characteristics of the materials and in hotpot seasoning in the role.Watercress make soup bittern, and produce color red leaves of spicy yaste and salty, increase the taste fresh fragrance, marinades LaoZao juice is increase fresh pressure xing, to smell, make soup halogen have the taste; to sweet Prickly ash can seasonings increase incense, pressure xing go bad smell. The dry chili increase soup halogen hot and fragrance; Salt set flavour increase incense, raises fresh flavoring, repression bad smell. Monosodium glutamate, yeast extraction content, chicken essence can increase fresh, also yeast extraction of freshness material things, can make the soup high-temperature brine long hot cooking and do not break full-bodied freshness; Ice-sugar go to dry back more than sweet smell; Five spices can go to dry, xing, polishing, etc.; Butter not but can provide hotpot base solid form, like, and vegetable oil also have increase incense role. 4.2.2 Selected raw material is making pot out based. For example, peppers and prickly ash, from season speaking, every year 7 8 months of prickly ash is produced from than October autumn pepper good quality.If the origin see, shaanxi, sichuan rich shun, xichang, yavin produce of MAO Chinese prickly ash, all seems MaWei foot, and aroma good quality. Choose Chinese prickly ash a as gas oil moisten, are choosing colors in grains, Chinese prickly ash, less seed, black branch stem less, flavour is lasting, with her teeth after the break MaWei foot flowers pepper for good. Dry chili from breed points have long chili, two gold,ChaoTianJiao, QiXingJiao and yunnan millet pepper, 2 bars chili color gas well, fragrance is, spicy gentle, while QiXingJiao, small ChaoTianJiao,Meters peppers smaller sharp is made, spicy incomparable, and therefore the pot Material can use both long, and with. Bean sauce to Sichuan PI county recently for authentic, fermented bean production in yongchuan fermented bean vin for good, other should buy good quality raw materials.4.2.3 Problems during the processOne is to stir fry watercress so red shiny hair color oil, fry the nun eat up the watercress flavour, watercress lovesyou easy also make sugar starch stewed turbidity; Stir-fry old watercress, make easily sauce black, tasteBitter. The second is tie-in, all kinds of spices spice must press proportion to join, otherwise, soup easy generation bitter and not suitable for incense flavour, also easy to change sichuan-style hot pot flavor.5 Product quality standard5.1 Sensory indexesDark in orange, with hot pot, distinctive flavor of production product is solid.5.2 Physical and chemical health indexAmino acids nitrogen (%) 0.20Total acid (with lactic acid plan %) 2.0Arsenic (As plan mg/kg) 0.5Lead (Pb plan) in 1.0Aflatoxin B(Ug/kg) 20总酸( 以乳酸计%) 2.0砷( 以As 计mg/kg) 0.5铅( 以Pb 计) 1.0黄曲霉素B( Ug/kg) 5.0致病菌 不得检出参考文献: 1 邓开荣. 制作重庆火锅的诀窍在哪里 J . 中国烹饪1991, ( 3) : 23- 25. 2 李乐清 四川火锅的汤卤调制 J . 中国烹饪.1989, ( 5) ; 12- 13. 3 沈祖耀. 调味佳品- 火锅底料 J .中国酿造.1993, ( 6) : 39- 42毕业设计(论文)外文翻译题目 螺旋输送式连续洗米机设计专 业 名 称 机械设计制造及其自动化班 级 学 号 078105114学 生 姓 名 刘家帅指 导 教 师 贺红林填 表 日 期 2011 年 3 月 18 日毕业设计(论文)开题报告题目 螺旋输送式连续洗米机设计专 业 名 称 机械设计制造及其自动化班 级 学 号 078105114学 生 姓 名 刘家帅指 导 教 师 贺红林填 表 日 期 2011 年 3 月 11 日一.选题依据及意义为适应食堂、大型饭店、快餐中心等的需要,我们设计研制了一种新型连续式洗米机。图1 机组结构简图1-料斗;2-水平螺旋;3-减速器1;4-电机1;5-机架;6-电机2;7-减速器2;8-沙石沉积槽;9-倾斜螺旋;10-出料口;11-喷水装置;12-溢流口该机组结构如图1所示,主要由料斗、水平螺旋、倾斜螺旋、机架、动力装置、喷水装置等部分组成。其工作原理为:大米至料斗加入,经过水平螺旋的输送进行揉搓洗涤,大米中的漂浮杂质在此过程中漂出,与洗涤的浊水一起从溢流口排出。大米经过水平螺旋输送洗涤完后,进入倾斜螺旋,在倾斜螺旋的入口处,沉降速度较快的沙石则被沉降在沙石沉积槽内(小槽下有螺孔,可定时拆下进行清洗),大米则随着倾斜螺旋的转动,被进一步揉搓洗涤并往上输送,最后经过喷水装置以上的沥干段沥干后从排料口排出,完成洗米操作。而洗涤水在洗米过程中从喷水装置处喷入,沿倾斜螺旋往下流动,经过水平螺旋,最后从溢流口流出。机组在整个洗米过程中水流与米成逆流流动,保证了较好的洗涤效果。为了确保水与米能成较好的逆流流动,在倾斜输送螺旋上钻小孔,并使倾斜螺旋的上盖与螺旋留有一定的间隙,水平螺旋则采用敞盖,也便于漂浮杂质浮出。机组设计主要特点:一是米在用螺旋输送过程中同时进行揉搓,使机组结构简单,运作可靠;二是米流成逆流流动保证了用水少和较好的洗涤效果;三是漂浮杂质有足够的漂浮空间,保证洗涤能较彻底地除去米中的漂浮杂质。螺旋输送机是粮食及机械加工等部门广泛应用的一种连续输送设备。螺旋输送机与其它输送设备相比,具有整机截面尺寸小、密封性能好、运行平稳可靠、可中间多点装料和卸料及操作安全、维修简便等优点。二、国内外研究概况及发展趋势(含文献综述) 过去二十年多年,许多研究工作者将带式输送机,用各种各样的线性模型来描述或者至少是便于数学计算的模型。在动力学分析中,由于输送带大变形和粘弹性的并存,使非线性问题变得十分突出,已达到了不能忽略的程度,而且许多不稳定的工程实例,使得它们的动态特性无法用简单的线性特性来解释。纵观起来,对于带式输送机系统的研究,在理论分析方面,采用线性动力学理论进行研究的较多,而采用非线性振动理论分析研究的极少;在系统设计方面,采用传统设计方法的较多,而采用现代设计方法的极少。 张力控制普遍采用速度检测的方法,将检测到的主动轮速度经过处理后控制送丝及收丝机构,再分别检测送丝及收丝速度,处理以后输入控制系统,从而形成闭环控制。这样做成的控制系统较为庞大,造价高。本文所述的方法简单实用、造价低,效果很好。 国外带式输送机设计系统 国外已有多家工程设计公司致力于带式输送机设计系统的研究,并开发出各具特色的满足不同应用要求的设计系统。美国cDI公司主要从事带式输送机的设计和咨询工作,在国际输送机设计领域处于领先地位,主要业务范围包括机械设计、水平曲线设计、动态分析和张力控制系统设计、设备调试及试运行等等。 澳大利亚的Helix Technologies Pty Ltd专门从事工程软件开发,已开发出一系列工程管理、投资分析的软件系统,如输送机设计、管道网络分析、泵的选型和V型输送带/链的驱动设计等。Overland Conveyor Co., Inc.(OCC)是美国一家专门从事散料运输的咨询公司,开发出的静态分析软件(Belt Analyst II)和动态分析软件(Dynamic Analyst),为用户提供带式输送机系统设计、工程和运行评估。国内带式输送机技术研究现状 近二十年来,我国带式输送机有了很大的发展,对带式输送机的关键技术研究和新产品开发都取得了可喜的成果。输送机产品系列不断增多,开发了大倾角、长距离新型带式输送机系列产品,并对带式输送机的关键技术及其主要部件进行了理论研究和产品开发,应用动态分析技术和中间驱动与智能化控制等技术,成功研制了多种软启动和制动装置及以PLC为核心的可编程电控装置。 目前,国内多所高校和科研机构在进行带式输送机的研究,辽宁工程技术大学在有限元分析、启制动曲线、水平转弯及断带检测等方面进行了研究.东北大学对托辊运行阻力随带速变化进行了实验研究,用于带式输送机设计和动态分析,分析转弯部分的导向力和阻力,得出转弯段输送带运行的阻力计算方法,采用离散模型建立系统的动力学方程,开发平面转弯带式输送机动态分析系统2-4;上海交通大学在带式输送机纵向振动理论与横向振动理论的基础上,提出了带式输送机的动态设计方法以及该方法与计算机技术相结合的设计决策支持系统。随着研究工作不断深入,带式输送机动力学性能研究积累了大量的宝贵经验和资料,利用新的设计手段研究带式输送机动力学模型的时机已经成熟。带式输送机的技术关键是动态设计与监测,它是制约带式输送机发展的核心技术。三、研究内容及实验方案l 总结和分析国内外带式输送机发展和现状;l 拟订机器的总体结构方案,进行机器方案的可行性分析;l 机器主要技术参数的确定与计算;l 进行关键零部件的设计与校核计算;l 设计机器的总体装配图;l 设计完成主要零件图的工作图;水平螺旋减速器设计 倾斜螺旋减速器设计五、目标、主要特色及工作进度(1)研究目标 本课题旨在设计一台螺旋输送式洗米机,该新型连续式洗米机结构简单、占地面积小、集搓米、洗米、除去漂浮杂质、沙石等于一体,采用水流与米流逆流流动,用水量少、洗涤效果好,是一种高效的连续式洗米机R机组。该机型除用于洗米外,也能用于豆类等其他颗粒性粮食的洗涤,是食堂、大型饭店、快餐中心及酿造、豆类加工作业中较为理想的粮食洗涤机械。(2)主要特色一是米在用螺旋输送过程中同时进行揉搓,使机组结构简单,运作可靠;二是米流成逆流流动保证了用水少和较好的洗涤效果;三是漂浮杂质有足够的漂浮空间,保证洗涤能较彻底地除去米中的漂浮杂质。(3)工作进度1. 查阅文献,熟悉课题及相关软件,撰写开题报告 2周2. 相关外文文献阅读与翻译(6000字符以上) 1周3. 拟定洗米机总体方案并进行方案分析 2周4. 进行主要零部件的设计与校核计算 2周5. 设计洗米机的总体装配图 4周6. 绘制主要零件图工作图 3周7. 撰写毕业设计说明书 3周8. 答辩准备及毕业答辩 1周六、主要参考文献 1包清彬. 新型连续式洗米机J. 包装与食品机械, 2001(3) 2贺新彬. 水射流输洗米机的开发和研制J. 粮油加工,2007(7) 3唐伟强. 新型连续豆豉洗霉机的原理及结构J. 中国调味品,2003(2) 4王中刚,张秀亲. 机械设计实践M . 哈尔滨:哈尔滨工业大学出版社,2003 5成大先. 机械设计手册全卷M. 北京:化学工业出版社,19996 A.W.
