First, our country puffs food development
food to puff the technology to have the glorious history in our country, ancient times on fried in oil the achievement to cause one of important methods which food puffed .As a result of all sorts of reasons, our country puffs the technological development to be slow. Until the 20th century the end of 70's, only then starts to puff the technology with to puff food the research. Along with living standard enhancement, the people to puff food the request to be more and more high.
Second, overseas puffs food and puffs technical the development
to puff the technology to take one kind of new food processing technology, is very quick in the overseas development. As early as US's Warder applied in 1856 to puff technical about food the patent. Japan carries on aggressive war period to the 40's once uses in the 20th century 30's puffs the technical processing corn's, the wheat class, again makes the military provisions after the suppression. In puffs in food domain, puffs the pot food the development to be most rapid, the American annual production has amounted to several hundred million US dollars .In recent years, the overseas use puffed the technical production to puff food mainly to have: Puffs the staple food, the man-made meat, potato food, the dehydrated apple, fast-food food, the pot food, fast dissolves the drink, a generation of young drink and the enriched food and so on. Also uses puffs the craft production starch and the processing grain.
Now, overseas food puffs technical and the theory research has been in the prosperous time. According to England "Financial Times" the near future reported; “The English food manufacturing industry recently to had 20 years history to puff the technology to have the interest once again, many food research center is studying food to change the complex process in the extruder. The food company hoped from puffs in the technology to excavate the new thingses product the manufacture method…”Recently, the French Mongte Pilley Europe linguistic science and the technical university's food biochemistry and the craft laboratory also denatured and the protein structure as well as the fast enzyme starch hydrolisis which occurred in the long tube continuous type extruder and so on has conducted the research to the protein.
In recent years, US's Frito-Lay Corporation, Japan's Calbee Corporation as well as Europe and Southeast Asia were very many famous puff food production enterprise to invest in abundance in China put up a factory, produce each kind to puff food.
American Frito-Lay Corporation in 1994 went into production only date type beefsteak after Guangzhou's joint venture Guangzhou hundred matter food limited company and the sea fresh taste corn crisp year sales volume amounts to 100,000,000 Yuan.
Therefore, develops vigorously puffs the technology and speeds up it to promote my armor food industry development in food production application step, is a topic which the present food scientific worker needs to consider.
Third, puffs food the prospects for development
to puff technical the appearance to be possible to say for the grain class, the starch class and so on these we called it opened a brand-new way the coarse edible grain raw material in food industry application. Moreover puffs food all to have after to blend flavors generally processing, therefore puffs food processing industry the development to will certainly to lead packing technology and so on seasoning industry and thin film development. At present applies the rice as the raw material to Puffing food production also is produces the factory a research development direction: Person and so on Eun at the IFT19.98 meeting proposed year after year the brown rice and the unpolished rice isometric mix, adds water to its moisture content is 18%, then produces one kind of Puffing Mi Bing in the 260r Puffing 6 seconds the method.
As research development personnel and manufacturer who puffs food, responds the heavy market survey research and the product renewal, strengthens unceasingly puffs the theory and the technical research, develops the new raw material, the new equipment and the new formula enhances own competitive power.
Our country puffs the food industry the development also to have this aspect lesson, because like 1980s initial period “the froth fruit” being published emerges “the extrusion puffed the heat” monotonously on because of afterwards the flavor, the variety pattern few causes this profession the development to bog down long period of time.
But US biggest puffs food production enterprise Frito - Lay Corporation is pays great attention to the product extremely in the global service swift and violent development reason the research development work, at the right moment promotes suits the people demand new to puff food.
Along with the food industry development, new technical and the new craft appearance as well as the people living standard enhancement, puffs the processing technology as well as puffs the equipment also inevitably unceasingly forward to develop, the production receives the low oil, the natural product which the people welcome.
The microwave puffs the technology, cures puffs the technology to take new puffed the technology already to bring to people's attention and gradually to obtain the application in the production. But the ultralow temperature will puff the technology supersonic, puffs the technology, chemistry puffs the technology all to have the possibility to obtain the actual application in the near future.
Fourth, at present needs to do the work

1. development advanced and the productivity big extrusion puffs the equipment

At present, our country's extrusion puffs the equipment quite to be backward, does not have the temperature, the pressure observation and control system and the digital demonstration. Overseas advanced puffs the equipment to realize for had estimated, puffs the temperature, the pressure automatic control and the numeral demonstrated, reduced the labor intensity greatly, enhanced the productivity.
Now overseas food puffs the equipment the type to be many, also has is suitable and so on public place use small food puffs in the entertainment machine, also has the suitable family use handy type to puff machine; At the same time, not only has the large-scale continuous type to puff the equipment, also appeared the automation to puff the equipment.
Our country puffs machine the variety, the specification are few, from now on will be supposed to develop the multi-varieties, the multi-purpose each kind of types vigorously puffs machine.
(2) develops positively puffs the theory and puffs technical the research
To carry on puffs the theory with to puff technical the research, is develops the performance good to puff the equipment and the processing delicacy puffs food deliciously the guarantee, overseas extremely takes regarding this.
For example, American Warm Ghale Company is equipped with the special research to trial produce the factory, has equipped 10 kind of different specification extrusion steam boilings machine, 10 kind of specification extrusion screw rods and 300 many kinds of extrusions die as well as other many kinds of equipment .Must carry on the near thousand time every year experiment, the research puffs the theory and new puffs the equipment to develop the new product.
Our country to puffs the theory and the technical research very is also insufficient, from now on will be supposed to strengthen puffs machine to the material compatibility, reduces aspect and so on energy consumption, new craft, new formula and reduced loss research.

1. develops the new product unceasingly, the production flavor diverse puffs food

Develops the new product unceasingly, the production flavor diverse puffs food, like the sweet taste, the salty taste, the sour odor and the fruit taste and so on puff food, satisfies the different taste consumer's need.
Our country puffs the pot food and the developed country compares, the disparity is very big. Many national grain puff the pot food shape and the taste many and varied, matrix raw material from the sole corn, develops the potato, the rice, the wheat, the rice noodle adds the ordinary starch and the denatured starch mixture.
Starts from the 20th century the beginning of 70's, US adds each kind of pot food with the above matrix raw material which the reinforcement, the soybean protein and the seasoning make to be all the rage the domestic and foreign markets, becomes the family, the park, the theater special-purpose snack, the sales volume is very big.
Puffs the food industry in our country is the emerging profession, the theory and the technical research, product quantity and the quality and the demand also has the very big disparity.In order to cause this profession healthy development, needs one group of special technical talented person.Should in the full display existing technical force foundation, the establishment puff the technology with to puff food the training center, causes the scientific research, the education, the production to unify closely, advances puffs the technology with to puff food the development
