Rice flour , or legumes such as beans or lentils , are sometimes used in place of wheat flour to yield a different taste and texture, or as a gluten-free alternative. Pasta is a staple food of Italian cuisine. Pastas are divided into two broad categories: dried pasta secca and fresh pasta fresca. Most dried pasta is produced commercially via an extrusion process, although it can be produced at home. Fresh pasta is traditionally produced by hand, sometimes with the aid of simple machines.

Italy is the Country were pasta manufacturing, along with related technical and machinery development, had and still have their top expression. From the beginning of , the artificial drying process allowed pasta to be produced at industrial level and therefore to be distributed to all regions of Italy first, and then internationally including big exportation volumes to USA.
Later on, importing Countries started to produce machines to manufacture and dry their own pasta. The drying process is the final main step of industrial pasta production, and it is fundamental to greatly prolong shelf life of the product many months to some years. This level is sometimes even lower than the initial semolina flour humidity e. Such deep level of dryness is not achievable with natural drying in acceptable times, therefore rooms or cabinets at controlled temperature and humidity are widely used.
Since the conditions of the inlet product and the drying cabinet are very different, a thermodynamic equilibrium condition is suddenly established at the beginning of drying, then the mass transfer provides the extraction of the rest of water from the bulk of the food. A liquid diffusion mechanism in solids like dough matrixes carries water at the interface between sample and air, where evaporation occurs.
Then, water diffuses as vapour through a gas medium often by a forced convection mechanism present in the drying cabinet in order to facilitate the process. Regarding the controlled temperatures applied for pasta exsiccation, it is possible to distinguish two different approaches:. Low temperature drying : it is a more traditional procedure, which involves prolonged exsiccation times ca.
For this reason, drying of high volumes of product requires big allowance of space and time, and as a result final pasta cost is quite higher. It is the drying procedure still used in many traditional and well renown Italian pasta production plants, using high range ingredients starting from semolina flour and including the kind of water used to obtain the dough.
These values are just indicative, as many different high temperature exsiccation protocols can be used by different production plants: in fact, high temperature HT and very high temperature VHT drying cycles are subgroups of this approach. An advantage of high temperature is to create pasta which has a good performance during cooking, remaining of the right consistency even if boiling is prolonged for a few extra minutes.
In fact, comparing HT pasta and VHT pasta, the latter has even higher quality scores based on sensory evaluation, total organic matter dispersed in cooking media water after cooking, and cooking loss of weight. These favourable effects of very high temperature drying probably depend on starch granules conformational changes evident at X-ray diffraction , and gluten protein denaturation.
Moreover, these effects are often present even if semolina flour used for the dough is not of excellent quality. Another advantage of the use of high temperatures is the achievement of an extremely safe product from the microbiological point of view. Despite all these advantages, including economical benefit thanks to much shorter drying times, high temperature drying approach can lead to some risks and damages to final products, e.
These problems arise if parameters are not well under control, e. As a result of a good drying cycle programming, overall pasta water loss is faster, and final product quality is higher. Regarding the effect of the drying step on pasta sensory characteristics, the multi-step Maillard reactions can play a role both on appearance and flavours of dry pasta: the relevance of these reactions not only depends on temperature level and length of its application, but also on raw material composition, in particular percentage of proteins and reducing sugars both precursors of Maillard reactions products.
The yellow colour could also be partly due to wheat selection in the last years, more oriented to carotenoid-rich grains. Maillard reaction entity can be monitored not only evaluating pasta colour but also, more accurately, measuring some marker substances e. At the end of the drying process, even if the value of moisture in the pasta is the desired one, it is necessary for it to be distributed uniformly inside the product so that all moisture gradients are zeroed especially if the pasta was dried with WHT cycles and in a short time.
The stabilization phase must keep the final moisture level in the product unchanged, even if a slight further decrease in moisture is possible. After completing stabilization, pasta can at last be cooled and reach the condition of being thermally balanced with the environment, ready for packaging. The most used pasta packaging is flow pack plastic, either for supermarket size pasta g to 1 kg or ho.

Pasta is a universal product consumed worldwide. It is most often made from durum wheat semolina and water with eggs, tomatoes or spinach included in some recipes , and comes in a wide variety of shapes and colors. Others flour grains may be used to process pasta, including whole cereals. Pasta is of course very popular because it is convenient, nutritional, economical and can be used in a great number of ways, as the base for a main course or as a garnishing. For short pasta, Clextral has developed custom-made processing systems that efficiently produce the main short pasta shapes: macaroni, penne, elbows, vermicelli, farfalle, angel hair, egg noodles, etc… and more innovative shapes too. Clextral short pasta production systems are designed to comply with the most demanding standards of hygiene, flexibility, consistency, productivity and maintenance.
The industrial production of pasta
Pasta is a universally enjoyed food, and almost every country serves a type of noodle. In China, it is mein; Japan, udon; Poland, pierogi; Germany, spaetzle. The popularity of pasta can be attributed to several factors: it is easily manufactured, it takes up little storage space, it is easy to cook, and it is rich in complex carbohydrates. Ancient Etruscan meals of gruel and porridge were eventually replaced with more appetizing unleavened bread cakes. Food historians believe these cakes may have been the precursor to pasta. Opinions about where the noodle originated vary.
Once the dough has been formed, the next process is extrusion. Dies are the accessories used to shape the water and semolina dough and are used to create the many pasta shapes available on the market. They are also highly technological, as in addition to shaping the pasta they also affect the characteristics of the pasta obtained, the thickness of each shape and the development and consistency of the gluten, the most important protein contained in durum wheat semolina. Its presence is fundamental for ensuring that, once cooked, the pasta has that elasticity and toughness, a sensation commonly defined as al dente Italian term meaning firm to the bite. Granoro pasta is produced using both Teflon and bronze dies: the type used depends on the characteristics that need to be enhanced for each shape, such as the colour, uniformity, porosity and roughness. Granoro produces more than different shapes of high-quality pasta in a number of ranges: standard pasta shapes, special semolina pasta, special egg pasta, special spinach pasta, special pasta from the Attilio range, special burnt wheat pasta and special pasta from the wellness range composed of organic, organic whole wheat and Cuore Mio pasta the latter produced from durum wheat semolina and barley flour. Last but certainly not least is the Dedicato range, symbol of a production range of the highest quality produced exclusively in Puglia, certified and traceable from the field to the table, the result of a food supply chain agreement between Granoro, the farmers and the mill that transforms the durum wheat into semolina. The dies used to produce the various pasta shapes after the dough has been kneaded are made to specific Granoro designs: the thickness is correct and carefully calculated to ensure the cooking time is not too long.
Pasta production, drying and packaging
Pasta, the most famous staple of Italian cuisine, was first recorded in Sicily in the 12th century, a few centuries after Arab invaders brought a dried, noodle-like dish to the island. It was not until the 18th century that industrialized production made it a cheap staple food for large numbers of Italians. Soft and pliable pasta dough is shaped into hundreds of different forms, from the simple strands and sheets of spaghetti and lasagne to bowties, seashells, wagon wheels and bicycles.
Italy is the Country were pasta manufacturing, along with related technical and machinery development, had and still have their top expression. From the beginning of , the artificial drying process allowed pasta to be produced at industrial level and therefore to be distributed to all regions of Italy first, and then internationally including big exportation volumes to USA.

The dies and the extrusion process
I make pasta from scratch every once in a while. It's easy to do, and the results are delicious. The process of pasta making is easier to show than to write about; so, this Instructable will mostly be pictures of the process with a little bit of written direction. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Measure out two cups of flour and dump them on a clean work surface. Use your hand to create a depression in the flour.
В последний миг перед погружением в забытье Элвин успел призадуматься о том, кто и как давно в последний раз шел этой дорогой. Солнце стояло уже высоко, когда они вышли из леса и наконец оказались перед горными стенами Лиса.
Земля перед ними круто вздымалась к небу волнами бесплодного камня. Река здесь заканчивалась столь же впечатляюще, как и начиналась: она с ревом убегала в разверзшуюся на ее пути расселину. Интересно, подумал Элвин, что же потом происходит с ней: через какие подземные ходы она движется, прежде чем снова выйти на дневной свет.
Что вы хотели мне сообщить. Олвин кинул взгляд на своего робота, Тот даже не шелохнулся. Вполне возможно, что он ничего и не подозревал и Олвин просто-напросто ошибался, полагая, что у робота есть какие-то свои планы.
Он почувствовал усталость, какой прежде никогда не знал; она словно расползалась из его ног, затопляя все тело. В этом ощущении не было ничего неприятного - скорее наоборот. Хилвар с веселой усмешкой наблюдал за ним, и у Элвина достало сил подумать - не испытывает ли его спутник на нем возможности своей умственной энергии.
Впрочем, он был далек от мысли протестовать по этому Свет, исходивший от металлической груши наверху, померк до слабого сияния, но излучаемое ею тепло не убывало.
Секундой позже облако распалось, и Криф возвратился, пронесшись над озером быстрее, чем мог уследить глаз. С тех пор он держался подле Хилвара и больше не пытался удрать. К вечеру впереди показались горы. Река, так долго служившая надежным проводником, теперь текла сонно, словно тоже приближалась к концу пути.
Вместе с ним из Зала Совета на улицы, сияющие красками и заполненные народом, вышел только Джизирак. -- Ну что же, Олвин,-- сказал.
-- Ты вел себя как нельзя лучше, но меня-то тебе не провести.
