Automated processes are normal apply within the food industry. Production effectivity isn’t the only motivation, hygiene also performs a key position in the meals trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the way to design a drive to satisfy these necessities and incorporate both these goals.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is selected to meet the excessive requirements for hygiene in the meals industry, we usually suggest our ADVANCED LINE air vane motors. pressure gauge วัด แรง ดัน น้ำ are produced from stainless-steel and are impervious to regular cleansing agents. The smooth 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 filth, water or different options can penetrate the motor. The motors are even immune to water penetration from commonly used cleaning spray systems. A moist setting is no concern for this motor. It may even be used underwater as in the case of many stirring functions. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and could be operated oil-free. A power discount of approx. 10-20% primarily based on the technical data stated within the product catalog must be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor must boast different features for such applications?
Answer: Yes. In many applications, condensation can kind in air provide strains. It is due to this fact advisable that measures are taken to ensure that the motor just isn’t located at the lowest level in the system and that it might be flushed out with water. Many users take precautionary measures, not solely relating to the layout of the motor in their system, but also concerning using water separators or dryers in front of the drive. If all this isn’t possible, then we suggest a particular coating for these elements inside the motor’s interior that are produced from stainless-steel. This is as a end result of there’s a limit to the use of chrome steel for heavy duty, high-speed inner elements. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you’ve any examples of the place your motors can be utilized within the food industry?
Answer: Stirring dough, shifting and slicing sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food industry applications are endless. I’ll describe a few functions in more element, similar to the use of our ADVANCED LINE air motor in an agitator for the manufacturing of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator at the velocity of seven-hundred rpm.
We also have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of areas. The 900W high-torque motor with a nominal velocity of twenty-two rpm overcomes a starting torque of 585 Nm and has a maximum diameter of 63 mm.
Another application may be present in grinding mills and conveying techniques for grain processing. In this case, the primary focus is on dust generation and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in potentially explosive environments. You will even discover our motors used within the processing of meat, for instance 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 via pieces of meat, onion and pepper. Pressure at the skewer is 38 kg and therefore a high-power air motor with compact design is ideally suited to this software.
Question: What benefits does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the principle advantages is its high power density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a third of its measurement. This is particularly vital when using a handheld device however of course also for robotic systems where the drive moves with the robot arm.
Heat also leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of vitality – it does not compare to the dangers of electrical energy. The energy output from the air motor over extensive torque ranges is sort of constant. Air motors can therefore be optimally operated in a large area of fluctuating masses. There is not any problem with load being utilized on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it will run again instantly and any variety of successive occasions. Air motor power could be tailored just by adjusting the working pressure. The pace is decreased smoothly by throttling the air volume. Throttling supply air is recommended when torque also needs to be considerably lowered. Exhaust air throttling must be chosen to scale back speed without any severe affect on the torque.
Question: Air motors are sometimes seen to be less efficient in comparison with electric motors. Can you touch upon this statement?
Answer: Air motors and electrical motors cannot be compared on a one-to-one foundation. The effectivity of a drive all the time depends on the circumstances of the application. Let me use this instance to explain: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at lowered velocity over a long period of time to secure the packaging tape. Electric motors cannot be loaded over a long period of time without working the chance of overheating. Therefore, for this packaging machine, an electrical motor would wish to withstand high loads and as a result would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You might select an air motor with a nominal torque of 15 Nm and nominal speed of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs near idle pace at 450 rpm under gentle load. The energy required for this air motor is therefore solely 430W. The vitality steadiness of an air motor is seen in a totally totally different gentle when you consider that the air motor wanted for this packaging machine would only require a third of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on a long time of experience within the subject of air motors. They have a extensive range of high of the range, globally in style industrial drive options. Are the ADVANCED LINE motors a special answer for food trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our standard program has been adjusted to satisfy the wants of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers profit from long-established dependable drive options for the food trade and medical know-how.
