1 國內(nèi)研究現(xiàn)狀
技術工藝是衡量一個企業(yè)是否具有先進性,是否具備市場競爭力,是否能不斷領先于競爭者的重要指標依據(jù)。隨著國內(nèi)馬鈴薯去皮機構市場的迅猛發(fā)展,與之相關的核心生產(chǎn)技術應用與研發(fā)必將成為業(yè)內(nèi)企業(yè)關注的焦點。了解國內(nèi)外馬鈴薯去皮機生產(chǎn)核心技術的研發(fā)動向、工藝設備、技術應用及趨勢,對于企業(yè)提升產(chǎn)品技術規(guī)格,提高市場競爭力十分關鍵。
馬鈴薯制品的主要品種有馬鈴薯條、馬鈴薯片、脫水馬鈴薯泥等。不論何種制品,其加工工藝都要求必須對原料馬鈴薯進行去皮處理,才能保證產(chǎn)品的質(zhì)量,保證其外觀、色澤和口感。馬鈴薯去皮的方法主要有人工去皮、化學去皮、機械去皮等。人工去皮的去皮效果較好,但效率低、損失率高,顯然不能適應馬鈴薯產(chǎn)業(yè)化發(fā)展的需要;化學去皮有熱堿法和低溫去皮液法兩種形式,主要依賴強堿溶液及特配化學去皮液的作用,軟化和松馳馬鈴薯的表皮和芽眼,然后用高壓冷水噴射,達到去皮目的。這種方法對去皮前后的沖洗工藝要求較高,且堿液或去皮液消耗量過大,成本較高,而且這種方法嚴重影響了產(chǎn)品的口感。機械去皮是摩擦去皮形式,主依賴馬鈴薯與馬鈴薯之間及馬鈴薯與金剛砂或橡膠之間的磨擦作用而達到去皮的目的,這種方法去皮效果好、降低了生產(chǎn)成本、減少了環(huán)境污染、操作簡單、速度快、可一人操作、效率高能實現(xiàn)產(chǎn)品利益的最大化。
2 馬鈴薯去皮機的工作原理
馬鈴薯去皮機采用臥式機型,主要包括工作圓筒,工作轉盤,機架和傳動部分(詳見原理圖)。當去馬鈴薯去皮機工作時,工作轉盤旋轉,物料由斗形進料口加入,物料落到旋轉刷輥表面上的波紋凸起上時,受離心力的作用由刷輥切線方向向上運動,物料不斷的沿工作圓筒壁運動,上升到頂部,又被頂部擋回落入工作盤表面。落到刷輥的粗糙表面并產(chǎn)生摩擦。物料在這樣的往復運動過程中,被猛烈翻滾攪動,從而形成了與刷輥、筒壁及顆粒之間的以翻轉、揉搓摩擦為主,撞擊為輔的綜合機械作用效果,從而達到去皮的目的。在摩擦去皮的同時,從進水孔注入清水,及時將擦下的皮通過刷輥與刷輥的縫隙沖至排渣口排出機體。在不停機的情況下,打開出料口的活門,物料由撥盤從出料口卸出。去皮后的馬鈴薯由去皮機構出料口滑槽進入輔助機構,經(jīng)過篩選等輔助工作后再進入下道工序。
3 總結
相信在不久的將來,一旦該產(chǎn)品應用到實際,將大大節(jié)省工作時間,提高工作效率,提高經(jīng)濟效益,同時將為大批量馬鈴薯生產(chǎn)做出巨大貢獻,帶動馬鈴薯產(chǎn)業(yè)更快更好的發(fā)展。機械去皮,以電機為動力,通過帶輪帶動圓筒底部的磨盤旋轉。磨盤上表面中間低、邊緣高,呈波浪形。塊莖加入圓筒內(nèi),因離心力和相互摩擦作用,在圓筒內(nèi)上、下、左、右翻動,并不斷地滾動;而圓筒內(nèi)壁的橡膠,將塊莖彈回,在磨盤和圓筒內(nèi)壁橡膠共同作用下土豆塊莖被均勻地磨去外皮,實現(xiàn)馬鈴薯去皮的目的。去皮時加入清水,再打開側門,塊莖從側門排出,皮屑隨水流從磨盤的周圍間隙排出。該機為間歇生產(chǎn),去皮機工作時,磨盤以一定的速度旋轉,滾筒內(nèi)的馬鈴薯在離心力、重力和摩擦力共同作用下,利用馬鈴薯相對于工作磨盤間的相對速度差,將馬鈴薯的皮去掉。

Potatoes peeled structure design
Abstract: the graduation design is mainly studied on the basis of the principle of friction of potato peeling machine design, working principle and the composition of the equipment. Through the analysis of original data, project demonstration and related data analysis and calculation, the overall design of a complete potato peeler to peel and mechanical structure is a new form, to better serve the fruits and vegetables to the development of leather industry, better adapt to the demand of the market both at home and abroad, so has the good market prospect.
Keywords: potatoes peeled structure; Friction; drive
1 the domestic research status
Technology is to measure whether an enterprise has the advanced nature, whether have market competitiveness, whether can keep ahead of competitors' important index. With the rapid development of domestic potato peeling agency market, the core of the related production technology and research and development will certainly has become the focus of the industry enterprises. Understand the potato peeling machine in the production of the core technology research and development at home and abroad, process equipment, technology, application and trend, for an enterprise to improve product technical specification, improve the market competitiveness is critical.
Potato products the main varieties of potatoes, potato chips, dehydrated mashed potatoes, etc. No matter what kind of products, its processing technology requirements of raw materials to deal with the peel potatoes, to guarantee the quality of the products, ensure its appearance, color and taste. Peel potatoes peeled methods mainly include artificial, chemical peeling, mechanical peeling, etc. Artificial to skin peeling effect is better, but low efficiency, high loss rate, obviously can not adapt to the needs of the development of the potato industrialization; Chemical peeling a hot alkaline or peel and low temperature liquid method in two forms, mainly rely on the strong alkali solution and liquid chemical peeling effect, softening and relaxation potato skins and body-to keep, then use high pressure water jet, peeled. This method the flushing process of before and after peeling the demand is higher, and liquid alkali, peel or consumption is too large, the cost is higher, and this way the serious influence the taste of the product. Mechanical peeling is friction peel form, the main dependence between potato and potato and potato with silicon carbide or rubber friction between role and achieve the goal of peel, good effect of this approach to skin, reduce the production cost, reduced environmental pollution, simple operation, fast speed, can one person operation, high energy efficiency to maximize the interests of the products.
2. the working principle of the potato peeler
The potato peeling machine adopts horizontal machine, mainly including working cylinder, work table, frame and transmission parts (see diagram). When to work in the potato peeling machine, wheel rotation, the material by a bucket shape inlet, material fall on the surface of a rotating brush roller corrugated bulge, the effect of the centrifugal force by the brush roller tangent upward movement, material constant along the motion for a cylindrical wall, rise to the top, was at the top of the block back into the working surface of the plate. Into the rough surface and friction brush roll. The reciprocating movement of the material in this process, by violent agitation, and formed with a brush roller, wall and between particles is given priority to with flip, rubbing friction, impact of comprehensive mechanical effects, so as to achieve the aim of the skin. At the same time of friction peel, from inject water into the hole, in a timely manner will be wiped off the skin of the through brush brush roll and roll gap to discharge mouth eduction body. In the case of non-stop, open the discharge valve of mouth, material by dial discharged through the discharge port. After peeling potatoes peel by institutions discharging chute into the auxiliary body, after screening and other auxiliary work again into the next procedure.
3. summary
Believe in the near future, once the product is applied to the actual, will greatly save the working time, improve work efficiency, improve the economic benefit, at the same time will make a great contribution for the mass production, giving impetus to the development of potato industry better and faster. Mechanical peeling, powered by motor, through the pulley drive cylinder at the bottom of the spinning mill. Low middle, high edge mill wheel surface, undulate. Tubers to join the cylinder, each other due to centrifugal force and the friction effect, within the cylinder up, down, left, right turn, and constantly rolling; And the rubber cylinder lining, will rebound tuber, in the mill and the cylinder wall under the function of rubber potato tuber is grinding to the skin evenly, achieve the goal of potato peeling. To skin with clear water, and then open the side door, tuber discharge from a side door, dander with flow from the discharge gap around the millstone. The machine for batch production, peeling machine, mill rotate at a certain speed, roller potato in under the action of centrifugal force, gravity and the friction, using potato work relative to the mill, the relative speed difference between the potato skin removed.
