Sweet potato deep processing technology and selection of mechanical equipment

sweet potato is a kind of crop widely planted in China. It has high yield and strong adaptability. It is planted in different areas all over China. Sweet potato is rich in protein, starch, pectin, cellulose, amino acids, vitamins and a variety of minerals, and has high nutritional and health value. In recent years, the development of sweet potato deep-processing projects has attracted more and more attention from all walks of life. Sweet potato deep-processing has become a model for the development of green health food. Sweet potato deep-processing has low investment, low risk and high profit, which can be extended to business opportunities in the industrial chain

sweet potato deep processing technology we take three powder processing as an example:

1, starch part:

stone removal - Cleaning - feeding - crushing - Separation - desanding - fine screening - concentration - dehydration - drying - screening

2 Mechanical production of vermicelli:

stone removal - Cleaning - feeding - crushing - Separation - desanding - fine screening - precipitation and powder extraction - mixing - blanking - molding - aging - freezing - powder drying (wet starch can directly deep process vermicelli, and dry starch is also easy to destroy starch viscosity)

3 Anti hand made flour noodles:

stone removal - Cleaning - feeding - crushing - Separation - desanding - fine screening - concentration - dehydration - drying - Screening - thickening - dough mixing - Secondary kneading - putting flour into the pot - curing - cooling - Pan powder hanging rod - freezing - loose powder drying (first, it is best to dry starch for processing, especially high starch sweet potatoes, which are difficult to put into good strips after drying, and the viscosity is poor after drying)

remarks: 1 The above equipment is equipped according to the production process steps of Ruyang Machinery Factory:

2. Three powders in a broad sense refer to starch, vermicelli, and vermicelli:

nowadays, the domestic sweet potato starch and vermicelli vermicelli Market is not empty, but the market is full of all kinds of flour products, but consumers rarely buy pure sweet potato vermicelli and vermicelli in the market, and even the younger generation does not know whether sweet potato flour is in their mouth, Most of the vermicelli and vermicelli flowing in the domestic market are processed by blending sweet potato, cassava, corn, wheat and other raw materials. The better processed ones are just poor taste, and the worse ones are inferior vermicelli, which are weak, sticky and easy to paste soup. In the final analysis, the vermicelli Market is driven by interests

in China, some people around us often say that there is a village or town in our hometown that makes noodles, and it is very famous. Of course, we believe in the noodles here at the beginning, because time and memory make us habitually think that this village noodles are good, but because of the drive of interests, polynil P240 LHSV also makes fake parts to reduce weight, and every family follows, so that consumers eat more and more inappropriate, At this time, this so-called famous village of noodles encountered the bottleneck of production and sales, and there may be two possibilities: 1. A large part of the collapse survived, and some of the surviving workshops may sell in the market. The wholesaler asked for noodles at what price, and I provided noodles at what price. Small profits but quick turnover, and slowly develop. Those businesses that fail to do business may reopen after seeing the business opportunities and learn from the successful model. The further development in the future, this place may become a base for making powder products, but the noodles produced in this base will be sold to other cities, and people nearby will know that the noodles here can't be eaten are fake. 2. Some producers may move away from the village and continue to produce in another place, but whether to produce pure finished products depends on the sales direction of the producers. There are many such villages or towns in China, which were originally known for their taste and quality of finished products, but later for their counterfeiting

II. Consumer psychology:

the production of traditional powder products such as noodles, vermicelli and powder skin has various specifications, various thickness and width styles. There are traditional habits of eating powder products in all parts of China, but due to different living habits and cooking methods, the thickness, width and width specifications of powder products in all parts of the country are also different, including the appearance and color of noodles. People in the south of the Yangtze River generally eat soup, hot pot and stew. Noodles are mainly made of noodles with diameters of 1.3, 1.5, 2.0 and 2.5mm. Wide noodles are generally made of flour products with thickness and width of 08*04, 08*06, 08*10 and 08*12mm. People prefer flour products with color bias. Flour products made of sweet potato, banana taro and pea are generally accepted by the public. People in the north of the Yangtze River generally eat fried, stewed, hot pot, cold mix, pastry and other materials. Noodles and vermicelli are mostly finished products with diameters of 055, 06, 07, 1.0, 1.2, 1.5 and 1.8mm. Wide noodles are generally flour products with thickness and width of 05*4, 05*6, 05*8 and 05*10mm. Flour products made of sweet potato, potato and wheat are generally accepted by the public. People in Northeast and Northwest China generally prefer thick and light powder products, but powder products made of sweet potato, potato and other raw materials are generally accepted in Northeast China, while powder products made of potato, sweet potato, corn and coarse cereals are easy to accept in Northwest China

the above four divisions are too general, but they are indeed simplified powder products that are often eaten in local life. China is a large country with a population of more than 1 billion. History divides us into different cities. In different environments, we all have different local cultures and different eating habits, but when we choose powder products, sweet potato powder is easy to be accepted by the public. In the above four divisions, According to the comprehensive evaluation of different regions, sweet potato noodles are the most popular among consumers

the soft, powerful and sweet potato flavor of sweet potato vermicelli makes people of the older generation have endless memories. Have we ever heard those old people say what a taste it is to put down the bottom powder lump when the production team puts down the flour. Of course, nowadays, there are a large number of production and sales of noodles all over the country, and there are wholesalers from all over the country. There are various colors of noodles and powder products of various thickness and width on the market, but where can we buy pure sweet potato noodles in rural markets and urban vegetable markets? In a word: it's difficult, adulteration may be the word we hear most in these years

flour products are a kind of traditional food and an indispensable part of our dishes. For traditional food, most people are consumers. We care more about quality and taste than price, but the demand for flour products is not our personal consumption, but a canteen or a restaurant. The flour products demanded in these places also restrict the quality of noodles purchased in the market, The Chinese market is like this. There is production when there is demand. I don't exclude the noodle enterprises that make mixed starch. This is also a kind of management and a way of survival. That is, the so-called way of survival makes the fake more fake and the real less

the so-called sweet potato noodles sold in the market are mostly priced at 2.5 yuan -3.5 yuan/Jin, 3.5 yuan -6 yuan/Jin. Consumers generally buy 6 yuan/jin of noodles, but what they buy back at this price is not necessarily pure sweet potato flour. Ordinary consumers do not have the ability to identify the true and false of flour products, mainly depending on the color and appearance, but these can be changed according to production

most of the areas where the production of noodles is concentrated in China do not have sweet potatoes, ranging from more than ten households in a village to hundreds in a township. There are at least threeorfour places in China on such a scale. Except for the hottest days in the four seasons of the year, overtime production is carried out at other times, mostly with cassava and corn mixed, low-grade corn starch is in the majority, and the noodles are mixed with pigments, alum, chemical and e-commerce packaging or end high growth additives, However, the noodles produced from samples with a certain size and shape in these places circulate all over the country. The local people in each production place do not eat these noodles, but they may also be produced in this way outside the market. Many people in the city will drag their friends or go to the countryside to buy the noodles produced by farmers. Rural people generally choose to provide sweet potato raw materials and supervise the production of equipment owners themselves. In such a domestic market, Many people are interested in the sweet potato deep processing project

nowadays, there are all kinds of large, medium-sized and small-scale manufacturers using sweet potato as raw material, from cleaning to powder molding. Small and medium-sized production meets local needs. Large enterprises should establish brand image and develop with a straight-line mentality. However, whether large-scale enterprises or small-scale enterprises, they should produce the powder products loved by the local public in a pure and additive free way. From the purchase of sweet potato to the processing of starch and noodles, every link can be seen by the people nearby on the spot, so that they can trust that these are pure sweet potato powder. Only the local people recognize, can there be a good sales market

III. selection of equipment:

1. Production overview

sweet potato deep processing this article introduces the processing of sweet potato starch, vermicelli, vermicelli, and flour peel, mainly because our Ruyang machinery factory has been engaged in the research and manufacture of potato starch deep processing equipment since the production of such equipment in 1982. The experience summarized and the application of the equipment are accumulated through long-term experience

2. Precautions

the selection of sweet potato starch deep-processing equipment should be based on the local actual situation, the area of sweet potato planting on the land or the area that may be developed, personal financial capacity, and sufficient power and water sources. It should be noted that sweet potato is a seasonal processing, which is usually excavated before and after frost. The processing season can last for days, and small-scale processing is generally about days. The reason is that fresh sweet potato used for beating pulp cannot be stored for a long time, and the saccharification and extraction rate of sweet potato starch stored for a long time is reduced. Secondly, the skin of sweet potato is softened and is not easy to be crushed. Starch processing and noodle processing are divided into two parts. Sweet potato processing is seasonal, and noodle processing should be continued after starch processing. The expected envisaged starch storage volume should be completed during the processing period for the processing of noodles

if the capital and the local sweet potato planting area allow, the primary processors can use a set of corresponding large-scale equipment. The whole set is equipped with a large amount of starch. Part of the starch is dry, part is wet stored, the dry is used for storage and sales, and the wet stored is used for self-processing vermicelli. For the vermicelli part, the size of the equipment should be selected according to their own sales or the production cycle should be reduced. Suggestions for users who have no sales: in the first year, the processing should focus on selling starch. The starch sales market is large, but the profit of selling starch is lower than that of noodles, but the sales of noodles in the first year will not be too considerable. The main purchase may be nearby farmers or simple packaging gift boxes. Do a good job in publicity. The sales of noodles and customers depend on time. Integrity-based, quality for survival, people value harmony, small customers will also bring big sales

3. Equipment selection

sweet potato processing equipment is mainly solid and durable with high extraction rate. Small ordinary farmers choose a set of equipment integrating cleaning, crushing and separation, which is simple and convenient. Sedimentation and powder extraction investment is small. After starch sedimentation, it is dug out, stored in a planned storage pool for wet storage, and then processed into vermicelli (drying treatment is required before March and April every year, and the weather gradually heats up, and starch will ferment), Small and medium-sized factories and large factories must choose an assembly line with separate equipment for crushing and separation
