背景技术Background technique

[0002] 用研磨、撞击、筛理、清粉等设备将已清理干净的小麦的胚乳与麦皮和胚芽分离,并把胚乳磨细成粉末状直接包装或经过配粉等处理,制成各种不同等级和用途的成品面粉和副产品的全过程称为小麦制粉工艺流程。其中整粒小麦清理车间(简称麦间)的工艺流程称麦间清理工艺流程,简称麦路:制粉车间工艺流程称粉间工艺流程,简称粉路。现有粉路分为皮磨、渣磨、心磨、尾磨和清粉五个系统(工序)。皮磨的作用是剥开麦粒,刮下大粒状胚乳,尽量多提取品质好的粗粒粗粉(行业术语称“造渣”),并在尽可能保持麸片完整的前提下,刮净麸片上残存的胚乳。通常用剥刮率(一定数量的物料由某道皮磨研磨,经筛理后,穿过粗筛的数量占本道系统流量或1皮磨流量的百分比)大小评价皮磨设备功能和工艺效果。其中占本道系统流量的百分比称本道剥刮率。渣磨的主要功能是造渣和提纯,即通过轻研碾掉碾碎麦皮上的胚乳和胚芽,并把含麦皮较多的物料分离出去,达到给心磨工序提供纯度较高的胚乳的目的。心磨的主要作用是将经皮磨、渣磨研磨后高方筛和清粉机筛理分离出来的纯度较高的胚乳研磨成粉。通常用取粉率(一定数量的物料由某道系统研磨后,粉筛的筛下物流量占本道系统流量或1皮磨流量的百分比)大小评价心磨设备功能和工艺效果。其中占本道系统流量的百分比称本道取粉率。尾磨研磨1心和2心研磨后高方筛和清粉机筛理分离出来的含麦皮和胚芽较多的物料,其主要功能是制粉和提胚。每道皮磨齿辊磨粉机研磨后的物料都由气力输送装置提升并送卸料器卸料,然后送高方筛筛出面粉(行业术语称筛粉)并把其余物料按粒度大小分为不同等级(行业术语称分级)后,分别送清粉机筛选或送磨粉机研磨。皮磨研磨后的在制品按如下标准分级:18W或22W以上的大颗粒物料称做粗麸片,粒度为18W/32W(即18W筛下32W筛上的颗粒)或22W/32W的物料称作麦渣,粒度为32W/54GG的物料称作麦心,粒度为54GG/9XX~12XX的物料称作粗粉,9XX~12XX的筛下物称作面粉。灰分值是评定面粉精度高低的主要指标,在粉路前段产出的灰分值低的面粉为高精度面粉,业内称前路好粉。[0002] The endosperm of the cleaned wheat is separated from the wheat husk and the germ by grinding, impacting, sieving, clearing, etc., and the endosper is ground into a powder and directly packaged or processed by powdering to prepare various grades. The whole process of finished flour and by-products is called the wheat milling process. The whole wheat cleaning workshop (referred to as the wheat room) process is called the wheat cleaning process, referred to as Mailu: the milling process is called the powder process, referred to as the powder road. The existing powder road is divided into five systems (process) of leather grinding, slag grinding, heart grinding, tail grinding and powder cleaning. The role of the skin mill is to peel off the grain, scrape the large granular endosperm, and extract as much as possible the coarse-grained coarse powder (in the industry term “slag making”), and scrape it as far as possible to keep the bran intact. The endosperm remaining on the bran. The function and process effect of the skin grinding equipment are usually evaluated by the stripping rate (a certain amount of material is ground by a skin mill, and after sieving, the amount of the coarse screen passes through the flow of the system or the percentage of the flow rate of the skin mill). The percentage of the traffic of the local system is called the stripping rate. The main function of the slag grinding is slagging and purification, that is, the endosperm and germ on the crushed wheat husk are crushed by light grinding, and the material containing more wheat husk is separated to provide a higher purity endosperm for the heart grinding process. the goal of. The main function of heart grinding is to grind the high purity endosperm which has been separated by slag grinding, slag grinding and high square sieve and powder clearing machine into powder. The function and process effect of the heart mill equipment are usually evaluated by the powder extraction rate (a certain amount of material is ground by a certain system, the flow rate of the sieve material of the powder sieve accounts for the flow rate of the system system or the percentage of the flow rate of the skin mill). The percentage of the traffic of the local system is called the current powder extraction rate. After the tail grinding and grinding 1 heart and 2 heart grinding, the high square sieve and the powder clearing machine are separated and the material containing more wheat and germ is used for powdering and embryo extraction. The material after grinding by each skin grinding roller mill is lifted by the pneumatic conveying device and discharged by the unloading device, and then sent to the high square sieve to sieve out the flour (industry terminology called sieve powder) and divide the remaining materials according to the particle size. After different grades (industry terminology), they are sent to the cleaning machine for screening or to the grinding machine for grinding. The article after grinding and grinding is classified according to the following standards: large-sized material of 18W or more is called coarse bran, and the material having a particle size of 18W/32W (that is, particles on a 32W sieve under 18W sieve) or 22W/32W is called Wheat dregs, the material with a particle size of 32W/54GG is called wheat heart, the material with particle size of 54GG/9XX~12XX is called coarse powder, and the material of 9XX~12XX is called flour. The ash value is the main indicator for assessing the accuracy of flour. The flour with low ash value produced in the front of the powder road is high-precision flour.

[0003] 在小麦制粉工艺流程中,辊式磨粉机(辊式磨粉机包括齿辊磨粉机和光辊磨粉机)是核心和最关键的设备。现有技术中皮磨工序用齿辊磨粉机碾碎麦粒,并达到工艺规定的造渣和脱皮效果。齿辊磨快慢辊磨齿齿锋倾斜交叉形成许多具有较强剪切作用的只有5°左右交叉角,磨辊在碾压过程中剪切产出大量粒度在0.15mm~0.4mm(0.15mm以下是面粉)带麦皮的细小胚乳粒。因为这些带皮的小胚乳粒的密度和悬浮速度等特性都与等粒度的纯净胚乳粒相差无几,把两者分离开的难度较大,所以现有技术不得不大量配置清粉机并采用“轻研细分,同质合并和循序后推”等措施,把粉路拖的很长,付出高昂代价处理皮磨研磨后的这部分物料,仍无法消除渣磨和心磨工序粉碎加工过程中把细小麦皮粉碎成麸星,混入面粉,导致面粉灰分增大,精度降低的现象。因此,产出大量带皮的细小胚乳粒是现有技术皮磨齿辊磨粉机研磨的最大缺欠。[0003] In the wheat milling process, the roller mill (roller mill including the tooth roll mill and the light roll mill) is the core and most critical equipment. In the prior art, the skin grinding process uses a toothed roller mill to crush the grain and achieve the slag and peeling effect specified by the process. Tooth roller grinding fast and slow roller grinding tooth edge oblique cross to form a lot of strong shearing effect only about 5 ° cross angle, the grinding roller in the rolling process to produce a large number of particle size in the range of 0.15mm ~ 0.4mm (0.15mm or less It is a flour) small endosperm with wheat husks. Because the density and suspension speed of these skinned small endosperm granules are almost the same as the pure granules of equal size, it is difficult to separate the two. Therefore, the prior art has to configure a large number of pulverizers and adopt " The measures such as light research and subdivision, homogenous merger and post-sequence push, etc., have long been dragged by the powder road, and the high-cost treatment of this part of the material after grinding and grinding has not been able to eliminate the slag grinding and heart grinding process. The fine wheat skin is pulverized into a bran star and mixed into the flour, resulting in an increase in the ash content of the flour and a decrease in precision. Therefore, the production of a large number of skinned fine endosperm pellets is the biggest drawback of the prior art skin grinding roller mill.

[0004] 现有技术皮磨工序通常设置4~6道,每道用齿辊磨粉机研磨。每道研磨在靠高压碾掉或碾碎粘附在麦皮上的胚乳的同时,也把没能碾掉或碾碎的胚乳压实在麦皮上,所以不能实现刮净麦皮上的胚乳(小麦胚乳平均含量是81%,现有生产线总取粉率一般为75%就是证明)的目标也是现有技术皮磨工序的缺憾。[0004] The prior art skin grinding process is usually set to 4 to 6 passes, and each is ground by a tooth roll mill. Each of the grindings is crushed or crushed by the high pressure to adhere to the endosperm adhered to the wheat husk, and the endosperm that has not been crushed or crushed is compacted on the husk, so that the endosperm on the stalk can not be scraped. (The average wheat endosperm content is 81%, the total powder extraction rate of the existing production line is generally 75% is proof) is also the shortcoming of the prior art skin grinding process.

[0005] 现有技术心磨工序采用光辊磨粉机。用光辊磨粉机研磨具有基本不损伤麦皮,产出面粉精度高,灰分低等优点,但光辊磨粉机研磨也有效率低、能耗高、取粉率低,淀粉破损率高和高强度研磨后物料温升高等缺欠。为消除研磨后物料温升高的缺欠,国外曾研发主轴空腔通水冷却的水冷辊式磨粉机,但因性能不过关未能推广应用。为弥补光辊磨粉机的取粉率低的缺欠,自上世纪八十年代开始,小麦制粉生产线在辊式磨粉机后采用了被称为撞击磨粉机和撞击松粉机的两种粉碎设备。与辊式磨粉机相比,撞击磨粉机具有结构简单、成本售价低廉、体积和占地面积小、安装维修方便,运行费用低、适用面广和操作简单等许多显著优势。因此在近二十年内,撞击磨粉机和撞击松粉机在我国小麦制粉行业已全面推广应用。但在大面积推广应用后,强烈撞击导致物料温升高和在多数场合产出面粉灰分比辊式磨高两个重大缺欠逐渐显现,所以,近两年又出现使用范围锐减的势头。[0005] The prior art heart grinding process uses a light roller mill. Grinding with a light roller mill has the advantages of no damage to the wheat husk, high precision of flour output, low ash, etc. However, the light roller mill has low efficiency, high energy consumption, low powder extraction rate and high starch breakage rate. After the high-strength grinding, the temperature of the material rises and the like. In order to eliminate the shortage of material temperature after grinding, a water-cooled roller mill with a spindle cavity water-cooling has been developed abroad, but its performance has not been promoted. In order to make up for the low powder pick-up rate of the optical roller mill, since the 1980s, the wheat milling production line has adopted two types of impact mills and impact pine powder machines after the roller mill. Kind of crushing equipment. Compared with the roller mill, the impact mill has many significant advantages such as simple structure, low cost, small size and small footprint, convenient installation and maintenance, low operating cost, wide application range and simple operation. Therefore, in the past two decades, the impact mill and the impact pine powder machine have been widely promoted and applied in China's wheat milling industry. However, after the large-scale application and promotion, the strong impact caused by the high temperature of the material and the fact that the output of the flour ash is higher than that of the roller mill in most occasions gradually appeared. Therefore, in the past two years, the use range has been sharply reduced.

[0006] 一项已公布名为“水冷式撞击磨粉机”的发明专利(专利申请号:201210186136.7)公开了一种在盖板上设置通水散热装置的撞击磨粉机。该机在室温30℃以下条件下,能把撞击后物料温度控制在50℃以下。[0006] An invention patent entitled "Water-Cooled Impact Mill" (Patent Application No.: 201210186136.7) discloses an impact mill equipped with a water-dissipating heat sink on a cover plate. The machine can control the temperature of the material after impact to below 50 °C under the conditions of room temperature below 30 °C.

[0007] 一项已公布名为“具有撞击粉碎和挤压剪切粉碎功能的粉碎机”的发明专利(专利申请号:201210481139.3)公开了一种在现有撞击磨粉机基础上改进设计的粉碎设备。它通过用外表面为锯齿形的L形耐磨构件把柱销两个工作面保护起来,L形耐磨构件是用锯齿形切向工作面和倾斜工作面和定子柱销扭转特定角度的方法,使设备具有了撞击粉碎和挤压剪切粉碎功能。当被加工物料粒度大于转子柱销与定子柱销之间最小间隙时,设备主要靠转子柱销和定子柱销对被钳持在两者之间的物料颗粒施加强大的挤压剪切作用力迫使物料颗粒破碎,所以称挤切粉碎机。当被加工物料粒度小于转子柱销与定子柱销之间最小间隙时,设备靠转子柱销是在空间撞击物料颗粒迫使物料颗粒破碎。因为锯齿形的切向和倾斜工作面,大幅度增加了有效撞击(指能迫使物料颗粒破碎的撞击)几率,设备粉碎功能大幅度提高,所以称高效撞击磨粉机。[0007] An invention patent entitled "Crusher with Impact Crushing and Extrusion Shear Crushing Function" (Patent Application No.: 201210481139.3) discloses a pulverizing apparatus which is improved in design based on the existing impact mill. It protects the two working faces of the pin by using an L-shaped wear-resistant member whose outer surface is zigzag. The L-shaped wear-resistant member is a method of twisting a specific angle with a zigzag tangential working face and an inclined working face and a stator pin. The device has the functions of impact pulverization and extrusion shear pulverization. When the material size of the material to be processed is larger than the minimum gap between the rotor pin and the stator pin, the device mainly exerts a strong pressing shear force on the material particles clamped between the two by the rotor pin and the stator pin. Forcing the material particles to break, so weigh the pulverizer. When the particle size of the material to be processed is smaller than the minimum gap between the rotor pin and the stator pin, the device leans against the material particles in the space to force the material particles to break. Because of the zigzag tangential and inclined working faces, the probability of effective impact (referring to the impact that can force the material particles to break) is greatly increased, and the crushing function of the equipment is greatly improved, so it is called high-efficiency impact mill.

[0015] 2皮前装有着水机。[0015] 2 is equipped with a water machine in front of the skin.

[0016] 本发明具有如下的优点:[0016] The present invention has the following advantages:

1.本发明最关键的创新点是超常规设计和使用挤切粉碎机,并用它取代齿辊磨粉机做皮磨工序主要造渣设备。1. The most critical innovation of the present invention is the ultra-conventional design and use of a squeezing and pulverizing machine, and it is used as a main slagging device for the dermabrasion process.

[0017] 如背景技术所述研发“具有撞击粉碎和挤压剪切粉碎功能的粉碎机”的初衷是提高设备的粉碎功能。按设备结构和工作原理分析,当被加工物料的粒度大于转子柱销与定子柱销之间最小间隙时,被钳持在挤切粉碎机转子柱销和定子柱销的锯齿形切向工作面之间的物料颗粒承受的作用力远比撞击磨粉机大,所以挤切粉碎机的粉碎功能很强。试验证明按尽力提高粉碎功能的原则设计的挤切粉碎机用于加工麦粒时,会产出25%以上低精度面粉和大量粒度不同的带皮胚乳粒,而产出高纯度胚乳粒的比例却远比现有技术少,根本无法满足小麦制粉皮磨造渣的工艺要求。为了实现用挤切粉碎机取代大部分齿辊磨粉机做皮磨工序主要造渣设备的设想,我们研发的改进方案是:[0017] The original intention of developing a "pulverizer having impact pulverization and extrusion shear pulverization function" as described in the background art is to improve the pulverizing function of the apparatus. According to the structure and working principle of the equipment, when the particle size of the material to be processed is larger than the minimum gap between the rotor pin and the stator pin, the zigzag tangential working face clamped on the rotor pin and the stator pin of the squeeze cutter The material particles between the materials are much more powerful than the impact mill, so the crushing function of the squeeze mill is very strong. The test proves that the squeeze pulverizer designed according to the principle of improving the pulverizing function can produce more than 25% of low-precision flour and a large number of different-sized skinned endosperm grains, and produce high-purity endosperm granules. However, it is far less than the prior art, and it cannot meet the process requirements of wheat flour grinding and slag. In order to realize the idea of replacing most of the tooth roller mills with the squeezing and pulverizing machine to do the main slagging equipment in the skin grinding process, the improvement plan we developed is:

1.1按挤切粉碎机结构和工作原理分析,如果用挤切粉碎机加工完整麦粒,挤切粉碎机转子柱销和定子柱销的作用力都直接作用在包裹着胚乳的麦皮上。远远超过麦粒抗剪切强度的作用力,必然将胚乳连同麦皮一起粉碎。麦皮强度高,韧性好的特性不起作用。如果用挤切粉碎机加工已破碎麦粒,则挤切粉碎机的转子柱销和定子柱销的锯齿形切向工作面钳持住物料颗粒状态绝大多数情况是:若转子柱销切向工作面贴近带皮胚乳的麦皮表面,则定子柱销切向工作面必然贴近带皮胚乳的胚乳粒表面(即转子柱销和定子柱销的作用力分别作用在麦皮和胚乳粒上)。此时转子柱销运动形成的挤压剪切力必然先将强度低的胚乳破碎,而胚乳一旦破碎,则转子柱销和定子柱销对被钳持住物料颗粒的作用力立即消失,所以强度大十几倍的麦皮在加工过程中的破损率必然大幅度降低。根据上述分析,在做大量创造性试验和分析试验数据以后,我们确定皮磨工序1皮仍采用齿辊磨粉机把麦粒碾碎,2皮用挤切粉碎机的设计方案。同时,为达到减少加工过程中麦皮损伤和少出粉多出渣的目的,我们专门研发出转子柱销与定子柱销之间最小间隙扩大到1~2mm的挤切粉碎机和在设备运转时把最外圈转子柱销的线速度控制在30m/s~70m/s范围内的工艺方法。试验证明上述措施能达到有选择粉碎(指在破碎胚乳的同时尽量保持麦皮完整)和适度粉碎(指少出粉多出渣)的超出常规的目标。1.1 According to the structure and working principle of the extrusion pulverizer, if the whole granules are processed by the squeezing and pulverizing machine, the force of the squeezing and squeezing rotor pin and the stator pin directly act on the wheat husk wrapped with the endosperm. The force far exceeding the shear strength of the wheat kernel will inevitably smash the endosperm together with the wheat husk. The high strength of the wheat husk and the good toughness properties do not work. If the crushed wheat granules are processed by the squeezing and pulverizing machine, the sawtooth tangential working face of the squeezing and pulverizing machine pin and the stator pin clamp the material granules in most cases: if the rotor pin is tangential When the working surface is close to the surface of the wheat hull with the skin endosperm, the tangential working surface of the stator pin pin must be close to the surface of the endosperm grain with the skin endosperm (ie the force of the rotor pin and the stator pin acts on the husk and the endosperm respectively) . At this time, the extrusion shearing force formed by the movement of the rotor pin must first break the endosperm with low strength, and once the endosperm is broken, the force of the rotor pin and the stator pin to clamp the material particles disappears immediately, so the strength The breakage rate of the wheat husk, which is ten times larger, is inevitably greatly reduced during the processing. According to the above analysis, after doing a lot of creative tests and analyzing the test data, we determined that the skin grinding process 1 still uses a toothed roller mill to crush the grain, and the 2 skin is used in the design of the extrusion mill. At the same time, in order to reduce the damage of wheat husk during processing and to reduce the slag from the powder, we have specially developed a squeeze pulverizer with a minimum gap between the rotor pin and the stator pin to expand to 1-2 mm and operate in the equipment. The method of controlling the linear velocity of the outermost rotor stud pin to be in the range of 30 m/s to 70 m/s. Tests have shown that the above measures can achieve the above-mentioned goal of selective pulverization (referring to keeping the husk intact while breaking the endosperm) and moderate comminution (referring to less slag removal).

[0018] 1.2.根据小麦麦皮易吸水,麦皮吸水后韧性增强,抗破坏能力大幅度提高,特别是麦皮与胚乳相连的糊粉层有极易吸水及吸水后瞬即膨胀,使麦皮与胚乳的结合力大幅度降低的特性,我们在2皮挤切粉碎机破碎加工前增加了一道着水润湿工序。大量试验证明,加入0.5%~2%的水,不仅使麦皮吸水后韧性增强,加工时破碎率降低20%以上,而且糊粉层吸水膨胀,麦皮与胚乳结合力降低导致破碎加工时大量胚乳粒从糊粉层处与麦皮剥离,大幅度增加了100%纯度胚乳和100%纯度麦皮的产出率(现有技术每道皮磨都是一个碾压的工程,在糊粉层处把胚乳从麦皮上剥离下来的几率很小)。此举使本发明皮磨造渣功能大幅度提高。[0018] 1.2. According to the easy absorption of wheat wheat husk, the toughness of the wheat hull is enhanced after water absorption, and the anti-destructive ability is greatly improved. In particular, the aleurone layer connected with the wheat hull and the endosperm is extremely easy to absorb water and swells immediately after water absorption, so that the husk and the endosperm The combination of the characteristics of the combination is greatly reduced. We have added a water wetting process before the crushing process of the 2 skin extrusion pulverizer. A large number of experiments have proved that adding 0.5% to 2% of water not only enhances the toughness of the wheat hull after water absorption, but also reduces the breaking rate by more than 20% during processing, and the aleurone layer swells and swells, and the binding force between the husk and the endosperm decreases, resulting in a large amount of crushing processing. The endosperm is stripped from the bark from the aleurone layer, which greatly increases the yield of 100% pure endosperm and 100% pure wheat (the prior art each skin mill is a compacting project in the aleurone layer). The chance of peeling the endosperm from the wheat husk is small). This makes the slag slagging function of the present invention greatly improved.

[0019] 1.3. 在对大量试验分析研究后发现采取上述措施后,2皮挤切粉碎机加工产出的大片物料中有20%左右是纯净麦皮,其余都是粘附少量胚乳粒的大多呈卷曲状的麦皮。大量试验证明用挤切粉碎机处理这部分物料工艺效果不如齿辊磨粉机,所以我们设计3皮仍用齿辊磨粉机研磨。但按本发明皮磨工序尽量降低麦皮破损率的设计思路,根据3皮来料中麦皮上粘附的胚乳粒远比现有技术大和来料中含20%左右是纯净麦皮等情况,3皮齿辊磨粉机齿辊的齿顶宽度增大到0.3mm~0.4mm,轧距0.4mm~0.5mm,并把3皮加工后用16W~22W筛筛理的剥刮率控制在50%~70%。试验证明采取上述措施使3皮研磨麦皮的破损率比现有技术降低30%以上。[0019] 1.3. After a large number of experimental analysis and research, it is found that after taking the above measures, about 20% of the large pieces of material produced by the two-squeezing and pulverizing machine are pure wheat husks, and the rest are mostly curled wheats with a small amount of endosperm granules. skin. A large number of tests have proved that the process of treating this part of the material with the squeeze pulverizer is not as good as that of the tooth roll mill, so we designed the 3 skins to still be ground with a tooth roll mill. However, according to the designing method of the skin grinding process of the present invention to reduce the breakage rate of the wheat skin as much as possible, according to the fact that the endosperm particles adhered to the wheat husk in the three skin materials are far more than the prior art, about 20% of the raw material is pure wheat husk. 3, the tooth width of the tooth roll of the 3 tooth roll mill is increased to 0.3mm~0.4mm, the rolling distance is 0.4mm~0.5mm, and the stripping rate of the 16W~22W sieve after the 3 skin processing is controlled. 50% to 70%. Tests have shown that the above measures are taken to reduce the breakage rate of the three-skinned wheat husk by more than 30% compared with the prior art.

[0020] 1.4. 根据挤切粉碎机结构和工作原理分析,因麦皮的厚度(0.15mm左右)和4皮来料的厚度(3皮轧距0.4mm~0.5mm即保证4皮来料中粘附微小胚乳粒的麦皮厚度不大于0.5mm)都比转子柱销与定子柱销之间最小间隙小,所以绝大部分4皮来料在被加工过程中没有同时承受转子柱销和定子柱销施加挤压剪切力的机会。其受力过程通常是在定子柱销把某一粘附微小胚乳粒的麦皮阻挡住的瞬间,高速运动的转子柱销强烈撞击,在撞掉或撞碎粘附在麦皮上的胚乳粒的同时必然迫使麦皮变位,并带动麦皮向前运动,从转子柱销和定子柱销之间空隙窜出。在此过程中麦皮也可能破损,但因空间撞击力远小于转子柱销和定子柱销同时施加的挤压剪切力,所以麦皮破损率必然大幅度降低。据此并根据小麦制粉生产线4皮刮净麦皮上胚乳的实际需求和现有技术4皮采用齿辊磨粉机工艺效果差的情况,我们设计4皮的优选方案是采用挤切粉碎机,并把挤切破碎机运转时,最外圈转子柱销的线速度提高到60m/s~90m/s。试验证明,上述措施使本发明4皮加工的取粉率比现有技术高1~3倍,同时可采用提高控制转子转速的方法把麦皮的破损率控制在与现有技术基本持平的水平。[0020] 1.4. According to the structure and working principle of the extrusion cutter, the thickness of the wheat husk (about 0.15mm) and the thickness of the 4 skins (3 skin pitch 0.4mm~0.5mm) ensure the adhesion of micro-endodermal granules in the 4 skins. The thickness of the wheat husk is not more than 0.5mm), which is smaller than the minimum gap between the rotor pin and the stator pin. Therefore, most of the 4 skins are not subjected to the extrusion of the rotor pin and the stator pin during the processing. The opportunity for shearing. The force-carrying process is usually at the moment when the stator pin blocks the bark that adheres to the micro-embryo grain, and the high-speed moving rotor pin hits strongly, knocking or crushing the endosperm adhered to the bark. At the same time, it will inevitably force the wheat husk to displace and drive the granules forward to move out from the gap between the rotor pin and the stator pin. In this process, the wheat husk may also be damaged, but the space impact force is much smaller than the compression shear force applied simultaneously by the rotor pin and the stator pin, so the breakage rate of the wheat husk is inevitably greatly reduced. According to this, according to the actual demand of the wheat flour production line 4 scraping the wheat husk top endosperm and the prior art 4 skin using the tooth roller mill process, the preferred solution for the design of the 4 skin is to use the squeezing and pulverizing machine. When the crusher is operated, the linear speed of the outermost rotor pin is increased to 60m/s to 90m/s. The test proves that the above measures make the powder extraction rate of the four skin processing of the invention one to three times higher than that of the prior art, and the method for improving the control of the rotor speed can be used to control the breakage rate of the wheat skin to a level which is basically the same as the prior art. .

[0021] 2. 本发明的另一重要创新点是用水冷高效撞击磨粉机取代齿辊磨粉机做心磨工序的主要制粉设备,用尽可能短的工艺流程和创造低温加工条件生产优质面粉。辊式磨粉机是现代小麦制粉工艺诞生的标志。一百多年来,它一直是小麦制粉生产线的核心设备。辊式磨粉机也有高强度研磨导致物料温升过高的缺欠。降低研磨强度无疑是造就低温生产条件的有效方法,但没有人能够或敢于这样做,因为需付出降低生产效率的代价是任何人都无法承受的。目前撞击磨粉机在小麦制粉工艺流程中是辅助设备。没有调控功能,制粉功能无法与齿辊磨粉机媲美,使用时有产出面粉灰分高和物料温升高等缺欠是人们对撞击磨粉机的固有认识。因此,迄今为止,根本没有人会想用撞击磨粉机取代齿辊磨粉机做心磨工序的主要制粉设备。为了实现超常规的创新设想,我们研发的改进项目包括:[0021] 2. Another important innovation of the present invention is that the water-cooling and high-efficiency impact mill replaces the tooth roller mill to perform the core grinding process, and produces high-quality flour with the shortest possible process flow and low temperature processing conditions. The roller mill is the symbol of the birth of the modern wheat milling process. For more than 100 years, it has been the core equipment for the wheat milling line. Roll mills also have the disadvantage of high-strength grinding that causes the material to rise too high. Reducing the grinding strength is undoubtedly an effective way to create low-temperature production conditions, but no one can or dare to do so, because the cost of reducing production efficiency is unaffordable to anyone. At present, the impact mill is an auxiliary device in the wheat milling process. There is no regulation function, the milling function can not be compared with the tooth roller mill, and the defects such as high output of flour ash and high temperature of the material are the inherent knowledge of the impact mill. Therefore, to date, no one wants to use the impact mill to replace the main roller milling machine for the heart grinding process. In order to achieve ultra-conventional innovations, the improvements we have developed include:

2.1 改进撞击磨粉机使它具有能替代辊式磨粉机的能力2.1 Improved impact mill makes it capable of replacing roller mills

在研发成功水冷式撞击磨粉机和具有撞击粉碎和挤压剪切粉碎功能的粉碎机(在心磨使用时称高效撞击磨粉机)的基础上(本发明发明人也是上述两项专利的发明人),把两者结合并增配调速装置即形成本发明所述水冷高效撞击磨粉机。水冷高效撞击磨粉机克服了原有撞击磨粉机的不可调控和加工过程物料温升高等缺欠,并把撞击磨粉机的粉碎功能提高1倍以上,为本发明小麦简化和高效低耗产出优质面粉创造优越条件。Based on the successful development of a water-cooled impact mill and a pulverizer having a function of impact pulverization and extrusion shear pulverization (referred to as a high-efficiency impact mill during heart mill use) (the inventors of the present invention are also inventions of the above two patents) The water-cooled high-efficiency impact mill of the present invention is formed by combining the two and adding a speed regulating device. The water-cooled and high-efficiency impact mill overcomes the uncontrollable of the original impact mill and the increase of the temperature of the material during the processing, and more than doubles the crushing function of the impact mill. This is a simplified and efficient low-cost production of the wheat of the present invention. Produce superior conditions with high quality flour.

[0022] 2.2. 摸索出能克服撞击磨粉机产出面粉灰分升高缺欠的工艺手段[0022] 2.2. Exploring the process means that can overcome the rising ash of the flour ash produced by the impact mill

通过大量试验发现用撞击磨粉机加工灰分在0.55%以下的来料,撞击磨粉机粉碎功能越强,撞击取粉率越高,产出面粉灰分越低(这与本领域技术人员的设想和看法相反)。根据撞击磨粉机结构和工作原理分析推断,空间撞击能把大块带皮胚乳破碎成小块带皮胚乳,但很难把粘附少量细小胚乳的麦皮粉碎成细小麦皮。大量试验证明了这一分析推断。据此,我们设计了1心和2心采用辊式磨轻研加水冷高效撞击磨强撞的工艺方案。辊式磨轻研虽然研磨取粉率明显下降,但可保证加工后物料温度在50℃以下,满足低温的设计要求,另外轻研足以把来料中带皮的胚乳粒碾碎呈较大麦皮上粘附微小胚乳的状态,有助于消除后续水冷高效撞击磨粉机强撞产出面粉灰分可能升高的弊端。而水冷高效撞击磨粉机强撞取粉率高的优势足以弥补辊式磨轻研的损失,并使1心和2心的本道总取粉率达到设计要求。Through a large number of tests, it was found that the impact pulverizer was used to process the ash with an ash content of 0.55% or less. The pulverizing function of the impact mill was stronger, and the higher the impact powdering rate, the lower the ash content of the produced flour (this is inferred by those skilled in the art. Contrary to the opinion). According to the structure and working principle of the impact mill, it is concluded that the space impact can break the large-sized skin endosperm into small pieces of skin endosperm, but it is difficult to crush the wheat skin with a small amount of fine endosperm into fine wheat skin. A large number of experiments have proved this analysis inference. Based on this, we designed a 1 and 2 heart process using roller mill light grinding and water cooling high-efficiency impact grinding strong collision. Although the grinding and powdering rate is obviously reduced, it can ensure that the temperature of the material after processing is below 50 °C, which meets the design requirements of low temperature. In addition, it is light enough to crush the endosperm in the incoming material into a larger wheat husk. The state of adhering to the micro-endosperm helps to eliminate the drawbacks of the subsequent water-cooling and high-impact impact of the strong impact of the flour mill. The advantage of high water-cooling and high-impact impact mill with high impact rate is enough to make up for the loss of roller mill light grinding, and the total powder extraction rate of 1 heart and 2 core can meet the design requirements.

[0023] 2.3. 在研发成功辊式磨轻研和撞击磨强撞相结合的工艺方法和粉碎功能高1倍以上的高效撞击磨粉机以后,我们把 1心和2心光辊磨粉机轻研取粉率确定为15%~25%,同时要求1心和2心两道心磨高效撞击磨粉机撞击后的总取粉率必须达到75%~85%。大量试验证明,达到这一指标是绝对有把握的。按80%平均值推算1心和2心产出面粉总量已超过来料的95%(现有技术对应数值是70%~80%),所以本发明把心磨工序大幅缩减到4道,仍足以达到生产线总取粉率不低于现有技术的设计指标。理论上分析推算,本发明至少60%以上的面粉是撞击磨粉机和挤切粉碎机产出的。撞击磨粉机和挤切粉碎机已取代辊式磨粉机成为小麦制粉的核心设备。这无疑是小麦制粉历史上的一场革命。理论上分析推算,本发明90%以上的面粉是只经1~2次高强度粉碎加工就产出的,而且1心和2心辊式磨轻研和撞击磨有水冷装置使本发明达到了低温、快速、高效,低耗生产优质面粉的设计目标。根据大量试验检测数据分析推断,按本发明设计的小麦制粉生产线与现有生产线相比有前路好粉出率提高20%以上,生产线总取粉率增大2个百分点以上,生产线产出面粉平均灰分值明显降低,加工全过程不破坏小麦营养成分,面粉食用品质和食品制作性能(包括面团易操作性能、发酵性能、蒸煮性能和烘焙性能等)优良及产出面粉保持小麦原始的香味等优势。[0023] 2.3. After the successful development of the roller-type grinding and impact-strength collision method and the high-efficiency impact mill with the pulverizing function more than 1 times higher, we put 1 heart and 2 heart roller mills are determined to have a powder rate of 15% to 25%. At the same time, the total powder extraction rate of 1 heart and 2 core heart mills must be 75% after impact. ~85%. A large number of experiments have proved that it is absolutely certain to achieve this indicator. According to the 80% average, the total amount of flour produced by 1 heart and 2 cores has exceeded 95% of the incoming material (the corresponding value of the prior art is 70% to 80%), so the present invention greatly reduces the heart grinding process to 4 channels. It is still sufficient to achieve a total powder extraction rate of the production line not lower than the design specifications of the prior art. Theoretically, it is estimated that at least 60% of the flour of the present invention is produced by an impact mill and an extrusion mill. Impact mills and squeeze mills have replaced roller mills as the core equipment for wheat milling. This is undoubtedly a revolution in the history of wheat milling. Theoretically, it is estimated that more than 90% of the flour of the present invention is produced by only one or two high-strength pulverization processes, and that the present invention has been achieved by a one-heart and two-heart roll-type grinding and impact grinding with a water-cooling device. The design goal of producing high quality flour at low temperature, fast, high efficiency and low consumption. According to the analysis of a large number of test data, the wheat flour production line designed according to the present invention has a better powder yield rate of more than 20% compared with the existing production line, and the total powder extraction rate of the production line increases by more than 2 percentage points. The average ash value of flour is significantly reduced, the whole process of processing does not destroy the nutrients of wheat, the edible quality of flour and the performance of food production (including the easy handling of dough, fermentation performance, cooking performance and baking performance) are excellent and the flour is kept to maintain the original wheat. Aroma and other advantages.

[0024] 3.皮磨工序用挤切粉碎机取代齿辊磨粉机做皮磨工序主要造渣设备,心磨工序用水冷高效撞击磨粉机取代光辊磨粉机做心磨工序主要制粉设备,心磨工序精简40%左右等措施,使本发明综合经济效益十分显著。按采用本发明的日处理400吨小麦生产线与现有技术日处理400吨小麦的生产线对比分析,其设备和土建投资减少30%以上,能耗降低15%以上,设备维修工时和费用减少20%以上(主要原因是挤切粉碎机和水冷高效撞击磨粉机转子和定子部件十年内可免维护),操作工减少30%以上,设备调控工作量减少70%以上(绝大部分设备一次调试成功后,至少数月之内不用动),和生产管理大幅度简化等诸多优势。[0024] 3. The skin grinding process replaces the tooth roll mill with the squeezing and pulverizing machine to make the main slagging equipment for the skin grinding process. The heart-grinding process uses the water-cooled high-efficiency impact mill to replace the light roller mill to do the main milling equipment for the heart grinding process. The heart grinding process is reduced by about 40%, and the comprehensive economic benefits of the present invention are very significant. According to the comparative analysis of the daily processing 400 tons of wheat production line and the prior art processing of 400 tons of wheat, the equipment and civil construction investment is reduced by more than 30%, the energy consumption is reduced by more than 15%, and the equipment maintenance time and cost are reduced by 20%. Above (the main reason is that the rotor and stator parts of the extrusion pulverizer and the water-cooled high-efficiency impact mill can be maintenance-free within ten years), the operator is reduced by more than 30%, and the equipment control workload is reduced by more than 70% (most equipments are successfully debugged at one time) After that, there is no need to move at least for a few months, and the production management is greatly simplified and many other advantages.

具体实施方式detailed description

[0028] 本发明提供了一种高效简化小麦制粉工艺,包括皮磨工序、渣磨工序、心磨工序、尾磨工序和清粉工序,皮磨工序设有4道皮磨。[0028] The invention provides an efficient and simplified wheat flour milling process, including a skin grinding process, a slag grinding process, a heart grinding process, a tail grinding process and a powder cleaning process, and the skin grinding process has four skin grinding processes.
