Introduction:
Chinese cuisine is renowned for its diverse and delectable dishes, and one of the most beloved breakfast items is the famous Chinese deep-fried doughnut known as "youtiao." With its crispy exterior and soft, fluffy interior, youtiao has become a staple food in China and has gained popularity worldwide. In this article, we will delve into the intriguing history youtiao and its evolution over the years.

Ancient Origins:
Youtiao traces its origins back to ancient China, with evidence of its consumption dating as far back as the Song Dynasty (960-1279). During that time, youtiao was known as "youzhaguo" and was primarily consumed by scholars and intellectuals. The unique shape of the youtiao, resembling the traditional Chinese "jian" (a double-edged straight sword), had symbolic significance, representing knowledge and wisdom.

Evolution and Popularity:
Over the centuries, youtiao underwent several transformations to become the beloved breakfast food it is today. Originally, it was made by twisting two pieces of dough together and frying them until golden brown. However, during the Ming Dynasty (1368-1644), a variation called "shaobing" came into existence. Shaobing featured a flakier texture and a rectangular shape, differentiating it from the traditional youtiao.

During the Qing Dynasty (1644-1912), the method of making youtiao was further refined. It became more elongated and thin, resembling chopsticks or oil-fried dragons, leading to its popular name "youtiao," which translates to "oil-fried devil." This name reflects the crispy and twisted appearance of the fried dough.

Symbolism and Superstitions:
Apart from its culinary significance, youtiao also carries cultural symbolism in Chinese society. In Chinese legends, youtiao is associated with a story about desperate scholars who drowned themselves in a river due to failing the imperial examinations. It is believed that the twisted shape of youtiao represents the intertwined fingers of these scholars, offering homage to their determination in pursuing knowledge.

Regional Variations:
While youtiao is commonly consumed throughout China, different regions have their own variations. In northern China, youtiao is typically thicker, longer, and has a softer texture, making it an ideal companion for soy milk or rice porridge. In the south, youtiao is thinner, shorter, and crispier, often enjoyed with congee or as an ingredient in various stir-fried dishes.

International Influence:
With the spread of Chinese cuisine overseas, youtiao has gained popularity around the world. It can now be found in Chinese restaurants and Asian supermarkets in various countries. In Southeast Asia, especially in Vietnam, Thailand, and Malaysia, youtiao is known as "cakwe" or "char kway," and it is often served with a sweet chili sauce or used as an ingredient in dishes such as "bakso" or "wantan mee."

Conclusion:
From its humble origins in ancient China to its widespread popularity today, youtiao holds a special place in Chinese cuisine and culture. Whether enjoyed as a breakfast item, a snack, or an accompaniment to other dishes, youtiao continues to captivate food enthusiasts with its distinctive taste and texture. It is a testament to the enduring legacy of Chinese culinary traditions and their ability to transcend borders and captivate taste buds worldwide.

I am a machine sales man , to be accurate, I am a sales man as well as a half machine engineer, as I have been in the food machine area for about 12 years. I witnessed the food machine development in Chinese market. At the beginning of the area, most of the machines were imported from abroad, such as from European countries, Janpan,etc. And most of the machines were from Taiwan province,China. To be honest, at that time, for example, 2005, the technology is not mature in China market, which made it difficult for Chinese food factories to buy the machine and make the products, as it replied on the import and the price was also very high at that time.

The Chinese nation is a nation that loves learing, during the coming 15 years, they developped the technology and strated to make the machines by ourselves, at the beginning, there is big difference on the machine quality compared with the machines from abroad, while with the continual improvement, the food machine has been more and more mature, and shared a good reputation not only in domestic market but also abroad. And now, China has exported the machines to and more countries and share good reputation.

In my memory, when I strat in this area, I learned the encrusting machine and the bread forming machine, at that time, this type machines are rare, when we made the machine, it can be sold easily..while as that time, people didn't have much knowladge on the machine and the recipe of the products, they can not make the product very profect, and they also didn't know that many products can be made by the same one machine..for example, for encrusting machine, it can make moon cake, maamoul, mochi, fish balls, cookies by the same one machine, that we called it multi-functional machine.. for the 380V 3Ph Pastry Production Line, it can not only make the pastry, but also can make bread, steamed buns, etc..

Now, with the development of the technology and the improvement of the knowladge on food recipes, we know much more of the machine and now, we can not only know how to make the products by the machine, but also need to know how to make it better..This is the requirment on the basis of the standard of the requests from market.

I have been in this area for 15 years, and for the next 15 years, I think I will also working in this area, as I like this area and there are much to be learn from it, learn from the excellent colleague, learn from brilliant people. In the future, there will still have much improvement in this area, we need to follow it, to improve ourselves, to make our machines better to serve more and more customers.

At last, we warmly welcome all of the customers from different places, different countries can come and visit us, we can discussed together and make small contribute to the food machine areas.

Appendix A (standard appendix)

Pilling boxes and accessories

A1 rubber cork lining

After a period of use, the surface of rubber cork may become smooth or adhere to grease, softener and finishing agent. These changes will reduce the degree of pilling. When this happens, wiping the rubber cork with methanol should restore the original pilling performance; if it still fails after wiping, the rubber cork lining must be replaced.

Method for determination of friction properties of rubber cork surfaces (see Appendix B). After a new pilling box is started or a new lining is replaced, the friction properties of the rubber cork surface lined in the pilling box must be measured to determine the changes in the surface friction coefficient after use and to understand the service life of the rubber cork. When the friction coefficient of rubber cork drops below 1/2 of the original value, it needs to be replaced with new rubber cork.

A2 sample tube

It is necessary to check whether the new sample tube has any traces of the model during manufacturing, and the convex surfaces at both ends must be smooth.

A3 check

The pilling performance of the instrument can only be checked directly with fabric. A certain number of two or more fabrics of different grades (from grade 1 to grade 4) should be selected as reference fabrics. Regularly or when necessary, use the reference fabric for testing, compare with the original sample, and determine the differences and changes in pilling boxes or the same pilling box.

Appendix B

(Appendix to the standard) Method for determination of surface friction properties of rubber cork linings

Measuring the surface friction properties of rubber cork can be used to judge the pilling tail energy of the pilling box. It is important to check the friction properties of the rubber cork surface regularly after starting a new pilling box, replacing the rubber cork lining, or during use.

B1 Equipment and Supplies

B1.1 A wooden block with a volume of 115mm×55mm×15mm and a weight of about 55g, and a string for weighing the plate.

B1.2 200g weight.

B1.3 Pulleys and pulley devices (see Figure B1). Figure B1 Device for measuring friction performance

B2 Operating Procedures

Car baler, also known as car body/car shell compactor press machine. Car baler is a new type of baler developed by TEYUN for scrap cars. It is mainly composed of three parts: body, hydraulic system and grab.

Car baler mainly packs various low-carbon and light-weight production and life scrap steel, scrap cars, and light metal structural parts made of steel into scrap steel blocks that meet the furnace charge. It is an ideal equipment for steel mills, non-ferrous metal smelting industry, precision casting industry and raw material production.

 

 

Features

1. The car baler has a large volume and opening area, a large feeding amount, and high working efficiency. It is extremely convenient for processing materials with larger shapes, especially for centralized feeding and taking materials.

2. Simple and easy to learn, intuitive and convenient operation.

3. PLC control is adopted, with high reliability and easy maintenance.

4. Each moving part is hydraulically driven, with stable operation and high working efficiency.

Horizontal baler is a type of baling machine that forms bales in a horizontal position, rather than the traditional vertical position. The machine typically consists of a pickup system that gathers the crop from the field, a conveyor system that moves it towards the bale-forming chamber, and a pressing mechanism that compresses the crop into a bale.

The main advantage of a horizontal baler is that it can produce larger bales that are easier to handle and transport. This makes it particularly useful for farmers who need to move large quantities of forage over long distances or store it for extended periods. Horizontal balers are also known for their ability to produce denser bales that have a more uniform shape and size, which can help reduce losses during storage and feeding.

 

The application of horizontal balers

Our horizontal balers are versatile, perfect for compressing waste paper, straw, grass, cotton, clothing, plastics, and other recyclable materials. They're also effective for soft items like yarn, cloth, woven bags, and more, making them an essential tool for cotton regions, textile companies, garment factories, and recycling stations.

We offer both fully automatic and semi-automatic models. The main difference lies in the strapping process; semi-automatic balers require manual strapping, while fully automatic balers feature an automated wire-feeding system for strapping.

One key advantage of our horizontal balers is the significant improvement in labor efficiency, as they are more efficient than vertical balers, helping to save on manpower.

 

Advantages of horizontal balers

1.Improve labor efficiency, save manpower. Horizontal balers have higher efficiency than vertical balers.

2.Save space, and reduce volume.

3.Reduce transportation costs and facilitate handling and processing.

Tips: Fully automatic horizontal balers cannot be used for baling metal. The semi-automatic horizontal baler can compress metal, such as cans, aluminum alloy profiles, stainless steel and other light and thin materials, but cannot be used to compress heavy scrap metal.

If you have interested in horizontal balers or vertical balers, please contact us.

Metal balers are special equipment for processing metal waste. After processing, various metal scraps, steel shavings, scrap steel, scrap iron, scrap copper, scrap aluminum, aluminum shavings, dismantled car shells, waste oil barrels and other metal raw materials can be squeezed into various shapes such as cuboids and cylinders. It is convenient for storage, transportation and recycling, and becomes a high-quality material for the smelting industry. This machine has an independent power device, and each moving part is driven by a hydraulic device. The work is stable and reliable. The main cylinder and the side cylinder are fully pressed forward. It is a good equipment to improve labor efficiency, reduce labor intensity, save manpower and reduce transportation costs.

The main factors that affect the compressive strength of cartons are: ① raw material quality; ② moisture; ③ box type and flute type; ④ printing and opening; ⑤ processing technology.

a. Raw material quality

The kellicutt formula is used to calculate the compressive strength of cartons based on the ring crush strength of corrugated cardboard, which is an indicator of the compressive strength of cartons. The ring pressure strength is the bonding strength between the core paper and the surface paper or lining paper. The raw material is the main factor affecting the ring pressure strength. It is related to the quantity, tightness, moisture, etc. of the raw material. The grades of containerboard paper and corrugated base paper mainly include A, B, C, D, E, etc. Under normal circumstances, the grade matching principle should be followed when selecting materials. The grade selection of containerboard paper and corrugated base paper should be similar. At the same time, the boxboard The basis weight of paper and corrugated base paper should be maintained within the range of 21, so as to ensure the overall quality level of raw materials and the quality of corrugated board. Of course, corrugated board is volatilized by the surface paper, core paper and lining paper bonded together, so the factors of adhesive and core paper should also be considered. The appropriate moisture content, tightness and uniformity of the core paper are conducive to the adhesion with the surface paper and lining paper. The good adhesive performance of the adhesive and the appropriate thickness of the adhesive layer are conducive to improving the compression resistance of the corrugated box. strength.

B.Moisture

The production environment, storage environment, use environment, weather, climate and other factors of the cartons will all affect the moisture content of the cartons. In order to ensure the compressive strength of the cartons, the impact of the external environment on the water content of the cartons should be avoided as much as possible.

The initial moisture content of corrugated base paper will directly affect the board-making quality of corrugated cardboard. If the moisture content is high, the base paper will be soft, but the tensile strength will be relatively reduced; if the moisture content is low, the base paper will be dry, and the top of the corrugated corrugated board will easily crack during corrugation. In the production of corrugated cardboard, the moisture content required to obtain the best strength value is generally 6% to 8%. The traditional method of determining moisture is the drying and weighing method at 105°C, using an oven and a balance. This method is the standard method.

C. Box type and corrugated type

Box type refers to the type of box and the size ratio of boxes of the same type, which have a significant impact on compressive strength. Some cartons are made of double-layer corrugated cardboard, and their compressive strength is significantly higher than that of single-layer boxes of the same specifications. Under the same conditions, the higher the box, the worse the stability and the lower the compressive strength.

In people's consciousness, they often think that the larger the flute type, the higher the compressive strength of the carton, and it is easy to ignore the impact of the flute type on the deformation. The larger the flute type, the greater the compressive strength and deformation of the carton; the smaller the flute type, the smaller the compressive strength and deformation of the carton. If the carton is too large, but the flutes are very small, the carton will be easily stained during the compression test; if the carton is too small, but the flutes are very large, the deformation will be too large during the compression test, and the buffering process will be long and effective. The deviation between the force value and the final force value is too large.

D. Printing and opening

Printing will cause certain damage to corrugated cardboard, which will reduce the compressive strength of the carton. The size of the pressure and the size of the bearing area are a major factor affecting the compressive strength of the carton. If the printing pressure is too high, the corrugations will easily be crushed and the flute height will be reduced. Especially when printing at the pressure line, in order to force and clear printing at the pressure line, the entire cardboard will be crushed and the compressive strength of the carton will be greatly reduced. Therefore, printing here should be avoided as much as possible. When printing graphics and text on the full page or around the carton, in addition to the pressing effect of the impression roller on the corrugated cardboard, the ink also wets the paper surface, which in turn reduces the compressive strength of the carton. When a general carton is fully printed, its compressive strength drops by about 40%.

For products that require ventilation in packaging, opening holes on the box surface or punching handle holes on the side of the box will reduce the strength of the carton, especially if the opening area is large or biased to one side, etc., the impact will be more obvious.

E. Processing process deviation

Through experiments, it was found that under the same conditions, for every 1mm widening of the transverse pressure line of the carton, the compressive strength of the carton decreases by 90N-130N, and the deformation increases by about 2mm. If the pressure line is too wide, the force value of the carton will increase slowly during the 1 compression test, the effective force value will be small, and the final deformation will be large. In order to ensure the compressive strength, we should try our best to improve the production process and reduce the impact of each process on the compressive strength of the carton. Improper crimping during the box making process, too deep grooves, weak bonding, etc. will also reduce the compressive strength of the box.
