Role of Magnet in the Food Adulteration

There are some materials mixed in food and those portions do not belong in food. That is the main cause of all the physical safety hazards. Those are the adulteration material as like metal, rocks, wood as well as other objects which are often found in raw ingredients. The nails from boxes and pallets, harvesting machinery parts, ingested metal from animals, veterinary instruments, lids and caps are the main sources of this material.

So actions are to be taken to protect the purity of the food product. To keep the food safe and hygiene you need to maintain a proper operating efficiency. Not only has the food you also need to think of the sanitary equipment design. An easily cleanable material with a readily accessible to all parts of the food processing equipment is needed.

Thus the food processors which help us in separating the adulterant material from food items are the separation equipment, come in the form of air cleaners, screens, magnets, sieves, metal detectors, traps and washers. There is several grain processors which use four screens to eliminate foreign materials mixed with it.

In the next step you have to determine the equipment that you need to keep your food items clean. Depending upon the processing material the magnetic metal separators as well as plate magnets are the best things.

The Cartridge-based separators have magnets in it. It is most likely to the drawer magnets, which are the best ones to handle vertical gravity flow of the food items. The processors are also available in self-cleaning models to go with the heavy contamination inconvenient locations.

In addition to this there are still other factors like product densities, operating temperatures, flow rates as well as the type of ferrous contaminants which would influence the choice of magnet material to be used as separator. You can use ceramic magnets material as a typical iron separation. However in a greater operating temperature an Alnico magnet is a correct choice.  In case of high densities and greater flow rate product high-energy Rare Earth magnets must be a suggested option.

Therefore, a group of factors influence the building standard that is required. That means depending upon the material only you can identify whether it need a cleanly flow through the system or a powder grade model is the correct option. A sanitary grade separators are required if the final products are proposed for human consumption. You cannot name the product purification as an accident. In each and every stages of production special attention should be paid for product safety and hygiene.

A Few Advanced uses of Magnets

Now with the advent of the modern technology of magnetic field, magnets are no longer limited to the use of sticking and fixing. There are various other major activities are there which facilitate your day to day life more easy and simple. Now magnets are used to produce turbo energy, its useful for making motors, plays an important role in the function of generator. Apart from its energy saving aspect the recent main advantage is its green environment alternative. All the electronic and technically advanced procedures have some hazardous effect on the environment. They reflect some poisonous gas of ray which is not good for human health. But luckily no such hazards are associated with the use of strong magnet. It is neither reactive in nature nor does produce any hazardous health effect. Rather this new concept of magnetic energy consumes 20-30% less energy as compared to the traditional electric energy system. Thus lots of scientists are trying hard to explore innovative ways to use magnet in more and more efficient ways to get maximum benefits. The following are some important uses of magnet in home appliances.

Audio Devices:

Magnets do the task of converting electrical energy to sound energy. The audio devices use this benefit of magnetic field from the ages long. That is the reason why magnets are used in the electronic appliances like microphones, headphones, stereo speakers and telephones. However in CD or DVD spinner, instead of converting to sound energy magnets turns the same to mechanical energy which make the visual display possible.

Vacuum Cleaner:

Your vacuum cleaners electric motor contains a set of electromagnets. When you turn the power on, the current flows into the magnets, produce forces that make the motor spin. Some electric motors use permanent magnets, while the other support electromagnets, however in one way or other they all depend on a moving magnetic field.

Household Appliances:

A magnet is a significant component which converts electrical power to mechanical energy and facilitate many modern applications. Often magnets play an important role in the function of many household appliances which has a motor or electricity mechanism inside. The appliances comprise all kind of electric fans, floor polishers, washing machines, electric toothbrushes and even vacuum cleaners. Apart from that magnets also exist inside power generators and power-supply transformers.

Common Tools:

There are certain tools that need magnetic field for their proper function. Think of the navigational compasses, which are used to indicate the direction in the air. It does not function with the help of electric energy or other power outsource.  It works with the magnetic field inside it even when you are in the middle of a sea just to indicate the direction. The north and South Pole of the magnet indicate the north and south direction.

Neodymium magnet strength grading

Neodymium magnets or more commonly known as NIB, NefeB or super magnets are the strongest as well as most widely used commercial magnets available worldwide. With the chemical composition of Nd2Fe14B, neo magnets have a tetragonal crystalline structure and are chiefly constituted of elements of neodymium, Iron and Boron. Over the years, neodymium magnet has successfully replaced all other types of permanent magnets for widespread application in motors, electronics and various other everyday instruments of life. Due to a difference in the requirement of magnetism and pull force for each task, neodymium magnets are easily available in different grades. NIB magnets are graded according to the material that they are made up of. As a basic rule, higher the grades, stronger will the magnet be.

The neodymium nomenclature always starts with an ‘N’ followed by a two digit number within the series of 24 till 52. The letter ‘N’ in the grades of neo magnets stands for neodymium whereas the following numbers represent the maximum energy product of the specific magnet which is measured in ‘Mega Gauss Oersteds (MGOe). Mgoe is the basic indicator of the strength of any particular neo magnet as well as the range of the magnetic field generated by it within any equipment or application. Although the original range begins with N24 however, the lower grades are no longer being manufactured. Nowadays the top manufacturers such as Stanford Magnets begin production of neodymium magnets from grade N33 and above. Similarly, while the maximum possible product energy of NIB is estimated to reach N64 yet such high energy levels have not yet been explored commercially and N52 is the highest current neo grade readily made available to consumers.

Any additional letters following the grade refer to the temperature ratings of the magnet, or maybe the absence of it. The standard temperature ratings are Nil-M-H-SH-UH-EH. These final letters represent the maximum threshold functioning temperature i.e. Curie temperature that a magnet can withstand before it permanently loses its magnetism. When a magnet is operated beyond the Curie temperature, the result would be a loss of output, reduced productivity and eventually irreversible demagnetization.

However, the physical size and shape of any neodymium magnet also plays an integral role in its ability to effectively operate at comparatively higher temperatures. Moreover, another thing to remember is that the strength of a good quality magnet is proportional to the number, so that N37 is only 9% weaker than N46. The most reliable way to calculate the exact grade of a neo magnet is through the use of a hysteresis graph testing machine.

Magnets can ruin your credit cards

You may all have noticed the magnetic stripes on all types of banking and credit cards. It is a strip of magnetic material which stores the significant data in digital. The stored data includes cardholder's name, expiration date, account number, etc. The process of Magnetic stripes was first invented in 1960 by IBM. It is a fast and secured procedure of online payment widely adopted by banks, airlines, hotels and departmental stores.

The important information about the user and its account necessary to do the transaction are placed on the magnetic stripe in an encoding data form. While swiping the card the data goes to the computer. The swiping of the card is equivalent to typing the same information but the process is useful only as it very fast.

Yes it is true that magnets can spoil the credit cards. If you rub a piece of neodymium magnet just directly touching the magnet across the magnetic stripe of the card, then the data encoded within it will be erased. So keep a distance between the magnetic strip of a card and a neodymium magnet for the safer side. For magnet and a credit card a 1” distance is advisable while in case of hotel room key low coercivity card 5-6” distance is needed.

Many of us has been experienced the fact that after certain number of usages, the magnetic card fails to work. It is a condition occurs when the magnetic stripe on the back of the card becomes obsolete or corrupted here the most likely culprit is the demagnetization. Now the magnetic stripes technology is practiced in almost everything starting from Master Cards to the subway tickets. Demagnetization on the contrary can be indicated as an accident. However there are certain environments which are responsible for the magnets getting demagnetized.

Here, exposure is the factor more responsible than strength of the magnet. If the card is exposed to a small magnet for long then it can harm it rather than a short exposure to a strong magnet. The important data necessary to do the financial transaction is encoded at the back side of the card in the black stripe area. A prolonged exposure of a neodymium magnet of strong magnetic field can erase the data permanently from the stripe and can make the card unreadable. So now after knowing how magnets can be the undoing of your credit cards, it is highly significant to take proper care to keep it safely.

The Maximum working pressure for sanitary butterfly valves

In its least difficult terms, a valve is a device that creates the stream of any specific substance, from gasses, fluidized solids, any sort of fluids, to slurries. Typically, this gadget manages the stream of such substances by opening, shutting, or partially blocking diverse paths. This sort of device is utilized as a part of various applications, including military, private, transportation, business, and obviously, mechanical applications. These valves are utilized as a part of two ways; either determined by weight, for example, for wellbeing reasons in steam motors, or utilized within a controlled way, in the same way as when determined by a camshaft, where valves assume a real part in motor cycle control.

Regarding the matter of valves, there is a great deal of sorts that might be utilized as a part of diverse ways. One specific kind of valve would be the butterfly valve. This valve is particularly utilized as a part of extensive channels, and is depicted as a circle turning on a polar pivot inside a channel, likewise utilized as a throttle valve or a damper. The butterfly valve is a kind of gadget that controls the stream, regularly used to control a certain liquid that would course through a certain area of a funnel. This valve is comparative (as to operation) to a ball valve. The butterfly valve, having a level roundabout plate, is situated in the middle of the funnel, and the plate has a bar through it that is joined to an idea about the outside of the valve. This valve works by pivoting the handle, and turning the plate over either in a parallel position, or perpendicular to the stream. Not like the ball valve, the plate in the butterfly valve is dependably there inside the stream; subsequently a sort of weight drop is constantly incited in the stream, notwithstanding the position of the valve.

Butterfly valves have three separate sorts. The elite butterfly valve, which is by and large twofold whimsical in configuration, is working the weight for up to 725 PSI. The second sort would be the flexible butterfly valve, which has an adaptable elastic seat. This sort would work the weight for up to 232 PSI. Lastly, the last sort would be the sanitary butterfly valve, which is regularly composed with metal seating. This valve works the weight for up to 1450 PSI.

There are additionally a few sorts of butterfly valves accessible in the business sector. Wafer style valves would be the most widely recognized, since individuals who get to request such would not by any means say the statement "wafer", yet at the same time get the butterfly valve that they need. This kind is under plastic butterfly valves, which is accessible in two styles, the wafer and the haul. Then again, haul style valves have metal embeds that are created in the jolt gaps of the valve. These supplements are strung on both closures, and this alone permits them to be situated into a particular framework with the utilization of two fasteners and no nuts. Likewise called a butterfly damper, this valve basically controls the stream by utilization of a circle through a particular port.

Top neodymium magnet coating

Neodymium magnets are infamously known as the strongest magnets that are commercially available throughout the globe. The widespread applications of neo magnets in all aspects of life both domestically as well as industrially means the exposure of these super magnets to various types of atmospheres and environments. NeFeB mainly constitutes the elements of neodymium, iron and boron. Therefore, this product is very vulnerable when exposed to the open atmosphere and will most definitely corrode and rust over time if not protected with a suitable permanent layer of coating on top. In the absence of a surface finish, neodymium magnets would easily chip, break and lose its magnetic ability very quickly.

There is a wide range of magnet layers available within the market. Among all the types of surface neodymium coatings the most widespread and commonly used is a nickel application. The basic benefit of nickel is that it hardens the magnet surface and does not allow chipping or breakage easily. Many a time’s two elements are combined to strengthen the shield around the magnet. A standard nickel – copper – nickel coat is such an example. This coat along with being extremely corrosion resistant is also very shiny and aesthetic to look at. Other types of coating include epoxy resin, zinc, gold and rubber coats etc are used in the plating of permanent magnets. While Ni-Cu-Ni coat is the strongest however not being waterproof, the plastic epoxy layer is more suitable for wet environments. Another property of neo magnet coating is that it is generally very thin and is always applied after completely drying the permanent magnet in order to avoid any form of rusting from the inside out. The choice of buying any particular coat also depends upon the user’s prerequisite. For instance, a gold coat is ideal for medical equipments in a situation where an inert non-reactive metal is integral for health regulations. On the other hand, a rubber coat would increase friction and be considered more friendly for installation in huge machines within the industrial sector.

Therefore despite advancements and improvements with added research, it is still strongly recommended to always protect a neo magnet from moisture through an outer coat. It should be known that, irrespective of any type of coating, over time all NeFeB’s are bound to corrode and no magnet can survive forever. However, the quality of any specific coat is of fundamental importance and is the basic determinant of a neodymium magnet’s life.

How Neo Magnets are made

1. Get ready Materials for the Reaction

The essential compound for most Neodymium magnets is Nd2fe14b. In practice, the real compound response utilized might be more muddled. A regularly utilized response is:

57 Fe + 8 B + 10 Fe2o3 + 7.5 Nd2o3 + 52.5 Ca -> Nd15fe77b8 + 52.5 Cao

Vacuum Induction Furnace

Note that the powder framed by this response is somewhat unique in relation to the Nd2fe14b proportion. Magnets are regularly made both Nd-rich and B-rich, where completed magnets commonly hold non-attractive bits of Nd and B in the grain, inside which are exceptionally attractive Nd2fe14b grains.

For higher temperature magnet reviews, extra components are included. At the point when little measures of Iron (Fe) are supplanted with Cobalt (Co), the properties enhance at hoisted temperatures, yet the natural coercivity diminishes. In the event that little divides of Neodymium (Nd) are supplanted with Dysprosium (Dy), the inherent coercivity is enhanced; however the greatest vitality item (Bhmax, a great measure of a magnet's quality) diminishes. It is regular to utilize both Co and Dy together.

2. Dissolving

The concoction response portrayed above happens in a vacuum affectation heater. The items are warmed by making electrical swirl momentums through it, all in a vacuum to keep contaminants out of the response.

3. Processing

Plane processing transforms the ensuing material into a powder with a little molecule size. The normal molecule size is on the request of 3 micrometers.

4. Pressing

Pressing Steps

The powder is pressed together to structure a strong that has a favored charge bearing. In a system known as kick the bucket annoying, the powder is pressed with a bite the dust into a strong at hoisted temperatures of something like 725°c. The robust is then set in a second bite the dust, where it is compacted to a more extensive shape that is about a large portion of its unique stature. This adjusts the favored course of polarization parallel to the pressing bearing. For a few shapes, there are routines that incorporate an apparatus that produces an attractive field amid pressing to adjust the particles.

5. Sintering

Sintering is a typical process in powder metallurgy. The material is layered at lifted temperatures (as high as 1080°c) underneath the material's liquefying point, until its particles stick to one another.

6. Machining

The sintered magnets are sliced to the coveted shape utilizing a pounding methodology. Less regularly, complex shapes are made with electric release machining (EDM). Due to the high material expense, material misfortunes because of machining are kept to a base. No successful method for reusing the waste has been produced.

7. Plating

The individual magnets are electroplated with three layers: nickel, copper and nickel. This is essential on the grounds that un-plated neodymium magnets are exceedingly inclined to consumption, and will rapidly lose their attractive properties in the vicinity of dampness.

8. Charge

Right now, the magnets have a "favored" bearing of polarization, however they are not polarized. They are put in an apparatus that will open the magnet to an exceptionally solid attractive field for a short minute. It's essentially a huge curl of wire encompassing the magnet(s). The charging supplies utilization banks of capacitors and a truly immense voltage to get such a solid present for a concise moment.

9. Examination

The nature of the ensuing magnets is examined for an assortment of properties. A computerized measuring projector checks the measurements. A covering thickness estimation framework utilizing x-beam fluorescence engineering confirms the thickness of the plating. Intermittent testing in salt-spread and weight cooker tests additionally confirm the execution of coatings. A hysteresigraph measures the BH Curve of magnets, which affirms that they are completely charged obviously for the magnet's evaluation.
