Communication power in the overall development of our country how? What are the problems to be solved? What are the latest relevant technology advances? Stage communication power technology going? Common concern for the readers of these topics, the reporter went to China before the opening of the communications equipment technology exhibition, through personal experience and communication, understand the communication power supply hot technology at the present stage of progress and the situation of production.

Communication technology rapidly to the diversification of power
Communication network development through the exchange of air separation from the simulation-based T DM Exchange network, the number of hours long process of development. The new century, NGN Research and commercial applications is becoming hot. Accordingly, also requires the rapid development of communication power supply technology to cope with network evolution. This reporter learned that, as a basis for the application of communication power, its technology and changes in different speed and other products, such as it is not the core network, access network and terminal equipment, as rapid development, but this does not mean stagnation Power Sources or old-fashioned one. In the exhibition scene, we see Emerson, power source, Section Chinese technology companies have demonstrated the power of diversification of products or even complete power solution, from which we can clearly see, the whole power supply technology toward multi-communication technology development. In specific products, the company exhibited to the audience AC / DC switching power supply, DC / DC switching power supply, UPS, AC variable frequency power supply, sine wave inverters and other new products, according to experts, in addition , electric operating power, high frequency rectifier inverter Welding Power, high-power high-frequency high-voltage DC power supply, chemical supply, and the green line with the trend of development Illumination Power, wind and solar power supply, also has been into the spotlight. Corresponding to these products, high frequency conversion technology, all resonant high frequency soft switch technology, power conversion technology and other advanced technologies are emerging, the emergence of these technologies to ensure the smooth flow of the entire communication network has made a great contribution.

High efficiency is the inevitable trend of development of communication power
Continuous research and development of new high-performance devices, the emergence and application, promote the upgrading of power products, making the power of the switching frequency is increasing. At present, power supply switching frequency up to 300kHz ~ 400kHz level, and small power supply has been achieved 1MHz switching frequency, and increased power density, which progress and development of power technology plays an important supporting role. In addition, the insulated gate bipolar transistor (IGBT), power field-effect transistor (MOSFET), a new magnetic materials and Transformer The application of new technologies also greatly enhanced power efficiency.

During the visit, the reporter learned that soft-switch technology, the leading issue of quasi-resonant technology research has become mature and stable, which is typical resonant transformation phase resonant, zero-switching PWM, zero-transition PWM, etc. new theory of topology, their focus is to reduce the hard-switching mode, the last opening of the power device, the switching devices during the switch voltage up / down and current up / down wave generated by wear and tear and noise overlap, and zero-voltage / zero current switching, reduce losses and improve power systems stability and efficiency. In short, the road towards the development of high efficiency not only in the enterprise, Operation The vital interests of the business, but also in response to a national call to build a conservation-oriented society.

Communications network power management to move
With the increasing popularity of Internet technology and the continuous development of information processing, communication systems from the previous stand-alone or small local systems development Tai LAN systems, WAN systems, so support the protection of telecommunications terminal equipment, the Internet aspects of electronic switch power supply must have the data processing and communications capabilities, including technical personnel can make the network at any time Monitor Power equipment operation status and the technical parameters of the smart user interface, with all kinds of protection, alarm and data information storage, processing, printing and other functions, and enables network technicians to exchange or preparation time switches Electricity Source of the remote switching machine function.

Show, we see the Emerson Network Power Monitoring System, which applies to all kinds of power stations for Telecommunication equipment and its environment in real-time monitoring and unified management. On the power management problem, the experts said, with the power management system, monitoring continuous improvement, we can achieve under different circumstances and flexible resource allocation, unified management, in order to ensure Telecommunications System reliability.

Communication to achieve full digital power control

At the show site, we also see a digital power control technologies. On-site technical staff to reporters about the construction of communication networks in China have their own coin, and in many areas such as natural environment and are relatively backward economy, communications facilities in those areas in which complex, sparsely populated, traffic inconvenience, no doubt increase of communication facilities, including maintenance of power systems communication difficulties, in this case, digital technology on traditional simulation technology to show the advantages can not be achieved.

Technology Is Killing Us

Posted on by

We use technology, in one form or another in our everyday lives, but it is the technology that man has created that is killing us. God put everything on the planet that was needed for humans to exist and he also made humans very smart, allowing us to educate ourselves far beyond what is needed in our everyday life.

God did not create our planet full of environmental toxins and yet they are a huge part of our everyday lives. Did you breathe today?? Then you were exposed to toxins. Did you drink water today?? Then you drank toxins. Our bodies were not designed to handle the toxic overload that we are exposed to.

If you don’t drink the toxic water, but instead drink sodas are you any better off?? Did you know that a can of soda can dissolve a nail within 3-4 days?? Can you imagine what sodas are doing to the inside of your body??

What about diet sodas?? Do you think that diet sodas are better for you than the regular sodas?? Did you know that the artificial sweetener, called aspartame, found in diet sodas and other foods was originally invented as an ant killer and that prolonged use can cause neurological disorders?? It’s true!! They found out that they could make more money selling aspartame as a sweetener than as an ant killer. Maybe it’s not the technology that is killing us but the old mighty dollar instead. How does that make you feel?? Your health is at risk so someone else can make more money. Then when you get a health problem, you have to spend even more money at the doctor’s office, which then might include having to take a prescription….which is more toxins added to your already toxic body.

Fluoride is added to our drinking water but too much can be toxic. Mercury is in vaccines, fluorescent light bulbs…etc. and can be toxic as well. All of the chemicals in our environment have been created by man for one reason or anther; whether it is a chemical we clean with, a chemical used to make drugs or some other type of chemical. We are surrounded in our environment with chemicals, most of which can be deadly and illness or disease related. 95% of all illness and diseases is toxin related. Now you know why I stress cleansing the whole body regularly.

A lot of people are trying to “Go Green”, which simply is an environmental friendly way of living, so we don’t further pollute and contaminate our planet that we live in. Going green products are safe for children, pets, plants….and everything in between. Going green means not having pesticides and herbicides on our vegetation.

Did you hear about the pesticide spill that happened in a lake in Florida back in 1980?? There was a huge decrease in the number of male turtles. What they found were a large number of turtles that were neither male nor female. Simply put, the reproduction organs did not form. It was found that the alligators had smaller than normal testes and penises. They also had elevated levels of estrogen and greatly reduced levels of testosterone. Can you imagine what these chemicals are doing to humans?? Think about a person that was born one sex and feels like they are suppose to be the opposite sex…have these same various types of chemicals altered their hormones?? Things that make you say, hummm….

I get that we use and need chemicals to do this, that and the other with but can’t they invent a natural concoction to do the very same job?? A toxic chemical had to be discovered and invented, so why can’t they just discover and invent a natural form to do the same job, that will have the same effect it the performance that it will do but will be environmental friendly??

Technology can be deadly and slowly it is probably killing us all. We need the world to be safe of these toxic chemicals for us all to have better health. Do your part and try to read labels and use more environmentally friendly, “Going Green” type of products both in your house, outside, around your kids and pets. We may not be able to clean the whole world up in our lifetime, but our kids are the future, let’s help make it a safer on

Introduction To Frozen Dough Technology

Posted on by

After working for years in the frozen dough industry, supplying frozen products to bakeries, cafes and restaurants, I had the chance and the pleasure to get quite a lot of experience in the production of good quality frozen dough. A good quality frozen dough product is a product which, after having been frozen for up to 6 months, still comes out of the oven as beautiful, appetising, attractive to the eyes and tasty as a fresh product. So it gives me a great pleasure to share with you some of the secrets about frozen dough production.

First don’t get mixed up with “Retarded Dough System” and “Frozen Dough Technology”. Those are two different ways of processing the dough, the first one is very simple and the second one is very much more elaborate.
– The Retarded Dough System is just normal dough that we place in a normal freezer, to be used up at a later time, may be 1, 2, or 3 days later. This dough loses some of its performance capability during the freezing process and cannot be kept frozen for more than a few days only. This is just a convenient process that we can use in some short term situations.
– The Frozen Dough Technology on the other hand is a very detailed and specific way of processing the dough, that enable the user to get the optimum performance out of the dough which has been frozen for a longer period of time. This period of time could be from just a few weeks to a few months; 6 months being regarded as a maximum for a live dough containing yeast. This is exactly what this article is all about.

First, how many kinds of frozen dough processes can we differentiate?
1) Ready to Prove Frozen Dough, good for most yeast dough and puff pastry as well.
2) Ready to Bake Frozen Dough, recommended especially for croissant and Danish pastry items.
3) Part Baked Frozen Dough, good for bread items, not recommended for croissant, Danish pastry items, and sweet bread and bun items.
4) Full Baked Frozen Dough, good for sweet bread/bun and soft roll, not recommended for bread, croissant, Danish pastry and puff pastry items.
5) Raw Frozen Dough Ready to Bake (Proving in the oven), not available yet, new technology still under intense research and development.

Critical points to succeed in frozen dough preparation
1) Make sure that the fermentation process does not start at any stage during the production.
To achieve that: one must control the temperature of the dough during all the different stages of the process, from the very beginning (mixing) to the very end (proving baking).
Ideally dough temperature must not exceed 16C (61F) during the mixing, dividing and filling of the products.
After the blast freezing procedure the ideal storage temperature is from -18C (64F) TO -22C (72F).

2) To keep the dough temperature under 16C (61F), at all time during processing, is the most difficult part and to achieve this goal we need to:
a) Keep the room temperature at between 16C (61F) and 20C (68F).
b) Use cold flour. Before use, the flour should be stored in a chiller (+4C) (39F).
c) Use cold water from a chiller or a water cooler.
d) Replace 25% of the liquid used (water/milk) with ice flakes. Or if ice flakes are not available the use of icy cold water (+2C) (35F) is recommended.
e) Work the dough straight away from the mixer without or with as little rest as possible between the different stages.
f) Freeze the dough, after shaping and filling, as fast as possible and this is when we need a blast freezer to freeze the product very fast up to the core. Why do we need to freeze the dough as fast as possible? The answer is: To bring the temperature deep inside the products to around -8C (17F) to -15C (5F) very fast, around 10 to 30 minutes, depending of the size of the products. This way the ice crystals formed during the freezing process are very small and do not damage the dough structure. If the freezing process is too long (from 3 to 6 hours with a conventional freezer) the crystals formed inside the dough are very big and will damage the yeast and the gluten structure. Then in this case the product will be very long to prove and will not rise to its maximum desired size, this is typically a low quality frozen dough.

Now looking at each kind of frozen dough processes one by one, we can say that for bread items the part baked system is the best and gives very good results. For croissant and Danish pastry items (as well as bread items) the ready to bake system gives outstanding results, but demands strict supervision, good equipment and premise.

Regarding the ingredients used in the production of frozen dough, they are almost the same as for the normal type of dough except two slight differences.
First, the yeast. Instant yeast and fresh yeast are both good to use but we always have better results with fresh yeast, products are faster to prove with more oven spring as well. Also when it comes to the quantity of yeast used, we have to increase it quite a lot (up to 2 to 3 times the normal quantity) to compensate of the yeast dying during the freezing process.
Second, the dough/bread improver used should be a special kind of improver for frozen dough only. There are many brands available on the market.

Hopefully this article has given you some useful things to think about before you start mixing the dough and I really hope you enjoyed this introduction to the process of frozen production.
