Automated processes are standard apply within the meals industry. Production efficiency isn’t the only motivation, hygiene additionally performs a key position within the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss the means to design a drive to meet these necessities and incorporate each these targets.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is selected to satisfy the high necessities for hygiene within the food business, we often suggest our ADVANCED LINE air vane motors. All their external components are created from stainless-steel and are impervious to normal cleansing brokers. The easy floor of these air motors is simple to scrub. The drives are so properly sealed with sturdy long-life radial shaft seals that no air can escape and equally no dust, water or different solutions can penetrate the motor. The motors are even proof against water penetration from commonly used cleansing spray techniques. A wet environment isn’t any concern for this motor. It can even be used underwater as in the case of many stirring purposes. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A power reduction of approx. 10-20% based on the technical data said in the product catalog should be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor have to boast other features for such applications?
Answer: Yes. In many applications, condensation can kind in air provide traces. It is due to this fact advisable that measures are taken to make certain that the motor just isn’t positioned at the lowest level in the system and that it could be flushed out with water. Many users take precautionary measures, not only relating to the format of the motor of their system, but additionally concerning the utilization of water separators or dryers in front of the drive. If all this isn’t potential, then we recommend a particular coating for these elements throughout the motor’s interior that are produced from chrome steel. This is because there’s a limit to the usage of stainless steel for heavy duty, high-speed internal parts. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you may have any examples of where your motors can be used within the food industry?
Answer: Stirring dough, shifting and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business purposes are infinite. I’ll describe a few functions in additional detail, such as the usage of our ADVANCED LINE air motor in an agitator for the production of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator at the speed of 700 rpm.
We even have the best drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of areas. The 900W high-torque motor with a nominal speed of 22 rpm overcomes a starting torque of 585 Nm and has a maximum diameter of sixty three mm.
Another application could be found in grinding mills and conveying techniques for grain processing. In this case, the main target is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in probably explosive environments. You will even find our motors used within the processing of meat, for example in a semi-automatic meeting system for the manufacture of kebab skewers. In the skewer unit, two air motors are used to drive belts which pierce a picket skewer by way of items of meat, onion and pepper. Pressure at the skewer is 38 kg and due to this fact a high-power air motor with compact design is ideally suited to this application.
Question: What advantages does an air motor have over an electrical motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the main advantages is its high energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a 3rd of its size. เกจวัดแรงดันsumo is especially significant when utilizing a handheld system however of course additionally for robotic systems where the drive moves with the robot arm.
Heat additionally leaves the air motor chilly. In crucial settings, compressed air is an unproblematic source of vitality – it doesn’t compare to the hazards of electricity. The power output from the air motor over extensive torque ranges is sort of fixed. Air motors can therefore be optimally operated in a wide subject of fluctuating masses. There is not any downside with load being utilized on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After reduction of the load, it’ll run once more instantly and any variety of successive occasions. Air motor power could be tailored simply by adjusting the working strain. The velocity is lowered easily by throttling the air quantity. Throttling supply air is recommended when torque should also be significantly reduced. Exhaust air throttling should be chosen to cut back pace with none critical affect on the torque.
Question: Air motors are often seen to be less environment friendly in comparison with electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be in contrast on a one-to-one foundation. The effectivity of a drive all the time is dependent upon the situations of the applying. Let me use this example to explain: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at reduced velocity over an extended time frame to safe the packaging tape. Electric motors cannot be loaded over an extended period of time with out working the risk of overheating. Therefore, for this packaging machine, an electrical motor would wish to face up to high hundreds and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally totally different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs near idle speed at 450 rpm under mild load. The energy required for this air motor is therefore only 430W. The vitality stability of an air motor is seen in a completely totally different gentle when you consider that the air motor wanted for this packaging machine would solely require a 3rd of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of expertise within the field of air motors. They have a wide range of top of the range, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special solution for food business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our standard program has been adjusted to satisfy the wants of our customers.
