Der Vego Riegel - vegane Schokoträume werden wahr!

Der Vego Riegel - vegane Schokoträume werden wahr!

Oft wird ein veganer Lebensstil mit gemischten Gefühlen gesehen. Veganismus bezeichnet einen Lebensstil, bei dem keine tierischen Produkte und Folgeprodukte (Eier, Milch, Butter, etc.) zu sich genommen werden. Für viele Menschen wirkt dieser Fakt abschreckend, da sie sich nicht vorstellen könnten, auf all diese Sachen zu verzichten. Da er jedoch in letzter Zeit immer populärer geworden ist, und sich mittlerweile nicht nur Stars und Sternchen, sondern auch Durchschnittsesser, und vor allem auch Ernährungswissenschaftler näher mit dem Thema Veganismus auseinandersetzen, werden auch vegane Alternativprodukte immer bekannter.

Ein besonderes Manko für viele Menschen am Veganismus ist der Verzicht auf Schokolade. In so gut wie jeder herkömmlichen Schokolade sind Milchprodukte enthalten. Somit fällt das überaus beliebte Genussmittel aus dem Speiseplan. Natürlich gibt es mittlerweile viele verschiedene Ersatzprodukte, um den Heißhunger auf Süßes zu stillen. Eines davon ist der Vego Schokoriegel, den es mittlerweile in mehreren ausgewählten Läden und natürlich online zu erwerben gibt. Der Vego Riegel hebt sich von der Masse der Alternativschokoladen durch mehrere Eigenschaften ab. Erstens ist er mit seinen 150 Gramm ein überaus großes Exemplar eines Schokoriegels und hat in seiner Optik eine gewisse Ähnlichkeit mit einem Toblerone-Riegel. Er hat keine flache Oberfläche, sondern eine leicht hügelige, an der man die ganzen Haselnüsse, die sich im Riegel befinden, sehr gut erkennt. Zu seiner Herstellung werden nur feinste Zutaten verwendet, unter anderem Haselnusspaste, Kakaocreme, italienische Gianduja-Schokolade und ganze Haselnüsse. Darüber hinaus sind die verarbeiteten Zutaten alle ausschließlich FairTrade-Produkte, das gewährleistet das FairTrade-Siegel auf jedem einzelnen Vego Riegel. Für den nicht so großen Appetit auf Süßes gibt es den Schokoriegel auch in der Mini-Version mit 65 Gramm.

Bei Konsumenten schneidet der vegane Schokogenuss sehr gut ab. Erstens aufgrund seiner Größe und natürlich wegen seines Geschmacks, auch preislich ist der Nuss-Schokoriegel für ein veganes Ersatzprodukt erschwinglich (ca. 3,50 für einen Riegel (150 Gramm)). Glutenfrei, vegan, bio und fair gehandelt - was will das Herz mehr?

Commercial Refrigeration powered by Secop compressors

The commercial refrigeration process can be quite complicated. Indeed, the technologies involved have dramatically advanced during the past few decades. While a portion of this momentum is centred around higher levels of efficiency, the need to reduce hydrocarbons within the environment has been another key motivating factor. Although this is a rather in-depth topic, it is still wise to take a brief look at how the refrigeration process works and what mechanisms are involved.

The Role of the Commercial Refrigeration Compressor

Perhaps the most important component of any commercial refrigerator is the compressor. This is a device which pumps refrigerant vapour through a series of coils at a high pressure. As this vapour travels through these coils, it meets the outside air of the kitchen and loses much of its heat. Then, the vapour will cool down the interior of the refrigerator. In essence, the compressor is the main device which enables the vapour to travel through the coils and keep the entire unit cold.

Evolving Needs

While the commercial refrigeration compressor may require much more coolant to be used, the underlying principles of vapour convection through the coils remains the same. However, it should also be noted that there are several types of commercial compressors which can be used. One is known as a variable speed compressor. As the name hints, it is able to automatically adjust its speed as is required to achieve optimal temperatures. This is ideal when one is looking to reduce energy consumption and electric bills. Also, it is said that this variant can last longer than a traditional model. Another useful mechanism is a variable-frequency drive. Once again, this drive will increase or decrease the speeds at which the compressor motor is running. As a refrigerator (even a commercial variety) is rarely operating at its peak capacity, variable speed drives (or VFDs) can help to increase the efficiency of the unit and lengthen the lifespan of the motor in question.

It is clear to see that this technology has vastly increased during the past few decades. As such systems continue to evolve, the consumer can expect to enjoy even more cost-efficient and reliable refrigerators.

Information about Hydrocarbons in a energy perspective

Hydrocarbons are used in compressors

Hydrocarbons are a great oil-less and energy efficient solution to compression motor systems. Where it’s been used in Europe and parts of South Africa, R290 and R60 cooling systems have reportedly used a fraction of previous power consumption under the same conditions at the same location. However the concerns which come with using this solution remain strong. This can be off-putting to companies who would like to be more energy efficient and consumers who don’t want to take on the risks associated with a more combustible gas. Hydrocarbons are flammable which means there are regulations on how much can be used per area and per recharge. In some places they are not allowed to be used.

The traditional method had been to use CFCs (Chlorofluorocarbons) which were very hard on the ozone layer. Then a mixture of HFCs (Hydrofluorocarbons)came along which was better for the environment but still lacking. It has been stated that refrigerant HFO-1234ze, a hydrocarbon mix, has a global warming potential of less than one. There are many variations of refrigerants using hydrocarbons with similar results, just look for the HFO at the beginning of the label.

Wikipedia: http://en.wikipedia.org/wiki/Hydrocarbon

There is considerable interest in the US to have restrictions on hydrocarbons relaxed or changed to reflect the individual situation. Studies with companies such as Danfoss suggest that a space can be designed or re-designed to make the use of hydrocarbons as refrigeration safe. Some potential uses for hydrocarbons include air conditioning and refrigeration for example small chillers to heat pumps as well as coolers and freezers for the larger commercial food industry. Additionally hydrocarbon compounds can be used in offices and homes as air conditioning and hydrocarbon gas compressors can be used on land and in marine use.

There are ways that compressors can be made even more efficient when used with hydrocarbons. For instance, with various monitoring software it can be easy for a technician to discover which part may not be working at its optimum calibration, or if one compressor in a series is suddenly no longer running before it puts a strain on the rest of the functioning units which may struggle to keep up with the cooling needs. Planned shutdowns for regular maintenance are advised even where the loss of one compressor will not hinder the work of the others. This can mean that the hydrocarbon compressor which is operating at a much lower power use which is monitored regularly can be effectively improved by simple monitoring of systems for functionality.

Variable Frequency Drive - energy saving compressor technology

Variable Frequency Drive

If you are running any kind of operation which involves electric motors large or small, it is likely you have already heard of the mysterious variable frequency drive. If you haven’t, it is high time you get informed because this invention can cut energy costs, increase production control and efficiency, and reduce equipment wear and tear. Read on for the full details.

What is a variable frequency drive?

The variable frequency drive, also known as an adjustable frequency or variable speed drive, is a special component of electro-mechanical drive systems which controls alternating-current motor speed and torque. It achieves this effect by varying motor input frequency and voltage. It is a component in electric motor systems which typically consist of an AC motor, a main drive controller assembly, and a drive-operator interface for adjusting the voltages and manual controlling.

Energy saving

Nowadays, up to 25 per cent of the total electricity consumption in the world is generated by electrical motors. Given that fact, it is astounding that variable frequency drives are far from widespread. Many fixed-speed electrical motors with an AC power supply can realise considerable energy economies if supplied with a variable speed drive. For example, a motor operating at 63 per cent its former fixed speed will use only about a quarter of its full-speed energy. This produces significant savings at a negligible speed reduction.

Wikipedia: http://en.wikipedia.org/wiki/Variable-frequency_drive

Process and performance control

Variable speed drives allow for much closer control of motor performance and, thus, improve the quality of operation and help maintain equipment. Fixed-speed motors habitually take high starting torque and experience current surges up to eight times the standard load upon starting. A system supplied with a variable frequency drive, on the other hand, will gradually rev up to the desired speed without the initial shocks. With the reduced stress, both mechanical and electrical, the life and wellbeing of equipment are prolonged. Another useful feature of variable frequency drives is that they facilitate running specific patterns on the motor, which can further help reduce shocks to the system and other undesirable effects. Acceleration and deceleration control are one prominent area where variable speed drives find extensive use.

An easy upgrade

Even if your equipment came with a fixed-speed motor, this is not a problem. If you determine you will benefit from the upgrade, you can retrofit a variable frequency drive easily.

Refrigeration Compressors Decoded

A refrigerator is by far one of the most remarkable inventions in the history of humanity. The process of refrigeration has not just improved the longevity of our food items, but has facilitated storage, preservation and availability of food throughout the year. It has made sure no fruit or vegetable really goes out of season, and can be accessed as and when the need arises. Given that refrigeration lowers the reproduction rate of bacteria, the rate of spoilage drops down drastically.

Working Process of a refrigeration compressor


Having started out as an ice-making machine in the late 1800s, the mechanics of refrigeration has grown by leaps and bounds over the years. One of the most important principles of refrigeration is that of vapour-compression. It involves absorbing heat from one space, removing it and subsequently cooling that space, eventually rejecting the heat elsewhere. Refrigeration compressor thrives on four components: a compressor, a condenser, a thermal expansion valve and an evaporator.

The refrigerant enters the compressor, is compressed to a higher pressure, which raises its temperature. This hot, compressed vapour reaches a temperature and pressure at which it can be condensed with either cooling water or air. The hot vapour is then made to pass through a condenser, where it is cooled and condensed into a liquid after putting it through a coil or tubes, with cool water/air flowing across. This is where system heat is rejected by the circulating refrigerant, which is lugged away either by water or air.

Different Types of Refrigeration Compressors


There are many types of compressors used for refrigeration. They are divided in either the positive displacement or non-positive displacement category. Positive displacement compressors house chambers that reduce in volume when compressed; the non-positive compressors, on the other hand, have fixed-volume chambers.

The five main compressor types are piston, screw, rotary, centrifugal and scroll.

Piston: It uses a piston and cylinder arrangement to provide compressive force. The reciprocating motion of the piston due to external power compresses the refrigerant inside the cylinder.

Screw: This uses a helical screw or rotor pair, which mesh together to compress the refrigerant between them. It produces high pressure for a small quantity of gas and consumes less power.

Rotary: It has two rotating elements, like gears, between which the refrigerant is compressed. Rotary compressors are considered to be the most efficient.

Centrifugal: This uses the rotating action of an impeller wheel to exert centrifugal force on refrigerants inside a round chamber.

Scroll: It is a quiet, smooth-operating unit with few moving parts and the highest efficiency ratio of all compressor types. It is also more flexible for handling refrigerants in the liquid.

Hydrocarbons - Definition, classes and chain lengths

A hydrocarbon is any chemical compound that is made of just carbon atoms and hydrogen atoms. They are obtained from crude oil by fractional distillation and can be classified in different groups. The four general classes of hydrocarbons are alkanes, alkenes, alkynes and aromatics. The first two groups are the most commonly known as they are used to obtain regular petrol or natural gas and in the production of plastic respectively.

Crude oil is a mixture of hydrocarbons with different carbon chain lengths. The length of these chains will have an effect in the ways how hydrocarbons can be obtained. Smaller hydrocarbons have a low boiling point and are quite volatile, making them ideal for ignition and they are not as useful. In order to obtain shorter chains, long hydrocarbon chains need to be cracked.

Cracking methods

There are two different methods to obtain shorter hydrocarbon chains:

Through thermal cracking. Hydrocarbon thermal cracking involves using high temperatures and low pressure. Here, long hydrocarbon chains are heated to temperatures up to 750 degrees Celsius and 70 atmospheres.

Catalytic cracking. This method is widely used by industries and it involves heating hydrocarbons at a low temperature, usually of 500 degrees Celsius and are passed over a zeolitic catalyst. This catalyst breaks the long chains and it provides a useful hydrocarbon chain.

Transporting short-chain hydrocarbons


As explained above, cracking methods allow for shorter hydrocarbons to be formed. Once these shorter chains have been obtained, due to their volatility, they need to be pressurised regularly, specially if the end product is natural gas. Compressors play an essential role in keeping this hydrocarbons pressurised as they will be transported from compressor stations to other locations.

A compressor stations is, therefore, a site where natural gas or hydrocarbons with very short chains are pressurised and transported. In order to do so, there must be compressor stations every 40 to 100 miles of distance. This will vary depending on terrain and the of wells in the vicinity. There are several types of compressors such as centrifugal compressors, reciprocating compressors, or diaphragm compressors.

The energy used to move a compressor is obtained from two sources:

- natural gas
- electric power

When the source is natural gas, it is the pipeline itself that provides it to the compressor. When it is electric power, this usually is provided by a nearby and highly reliable source. Moreover, this type of source may still require an air permit.

The Variable Frequency Drive - Why it works for industry

Variable frequency drive technology (VFD) has been developed to allow speed and torque control of an AC motor. This is achieved by connecting a variable frequency controller to an AC motor. Three phase induction motors are the most common though it is possible to connect it a single phase unit. In simple terms the controller converts AC to DC and then back to 'quasi-sinusoidal' AC power. This allows both the speed and torque of the motor to be controlled by varying the voltage and frequency.


VFD uses and benefits

Initially, the variable frequency drive was developed to give control of speed in various industrial processes, and to avoid the power surge associated with starting a single speed AC motor. However the variable frequency drive has found another purpose in compressor systems used throughout industry to provide a high pressure air supply. It has been calculated that 10% to 12% of power produced in the UK goes on creating compressed air. An air compressor that utilises variable frequency drive technology is able to switch speeds automatically, dependent on demand. This amounts to a real saving in compressor life as well as energy costs. With air compressors demanding such a significant amount of energy, it is easy to see why any potential reduction is of value to industry. However, this is not always the case.


Variable Frequency Drive costs

The main advantage of utilising a variable frequency drive is in the name – It ability to vary frequency and voltage, therefore speed. However, the drive unit is an expensive addition to a system and where, for example, the compressor is working at a high percentage of its capacity on a more or less permanent basis, there is little gained by the expense of having a variable speed capability. The cost of purchase and installation needs to be weighed against potential energy savings.


The end analysis

The concept and application of the variable frequency drive has found uses through industry in machine processes' allowing smooth start up sequences, variable speed control for different processes on the same equipment, control over production rate and generally, a more accurate degree of control over a myriad of industrial processes. With the high levels of energy required to power an air compressor, it could be argued that this singular process has most benefitted from the development of modern variable frequency drive systems; bringing both control and efficiency to industry.

The Usefulness of Commercial Refrigeration

Commercial refrigeration is used in a range of industries and, as such, there is a variety of refrigeration choices available. Industries that often use compressor refrigeration include:

  • Catering
  • Food Processing
  • Food Services
  • Retail
  • Transport
  • Oil

Depending on the industry, the type of commercial refrigeration used will vary in size and form. For instance, supermarkets require not only standard refrigeration but also cold displays. In large-scale factories, the refrigeration requirements often extend to keeping cool large open areas such as for preserving the freshness of meat.

The Wide Use of the Compressor in Refrigeration


No matter the size or form of refrigeration, however, it is likely that most types of refrigeration use some type of compressor system. To refrigerate an enclosed space, a refrigerant is compressed and decompressed in a compressor to draw heat out from an enclosed area. This method is widely used for domestic chillers also.

The Types of Commercial Refrigeration


Regarding the larger types of refrigeration, the walk-in freezer is a particularly common option, which can store large quantities of stock in an organised manner while allowing workers to enter and navigate easily. Stock such as food for a restaurant can be kept at optimum temperatures for as long as necessary, whether frozen or chilled. These compressor units are designed from materials that allow easy access while retaining cold air. On a larger scale, warehouses and factories will often use commercial refrigeration to chill large rooms.

Commercial refrigeration is also seen on the small scale in the form of displays in shops and supermarkets. Used to keep drinks chilled or food frozen, they can come in the form of open displays or closed displays with a sliding door. Closed varieties usually keep stock frozen and have a glass display window. For chilled food, an open display offers an easily-accessible option. While the open nature of this type of display may seem inefficient, a lot of the cold air used to chill the produce will sink to the bottom of the unit.

Businesses that Use Commercial Refrigeration


Commercial refrigeration is used in many types of businesses. Restaurants and food stores are widely known to use refrigeration, but florists do also. To prolong the shelf life of their flowers, many florists use refrigerated flower displays.

In the food production industry, refrigeration is a vital tool for maintaining the freshness of products. Factories will often have different areas for specific purposes (distribution, processing, etc.) and, therefore, will refrigerate at different temperatures using various compressor methods.
