Automated processes are commonplace apply in the meals industry. Production efficiency isn’t the only motivation, hygiene also performs a key function within the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to meet these requirements and incorporate both these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is chosen to fulfill the high requirements for hygiene in the meals industry, we usually recommend our ADVANCED LINE air vane motors. All their external parts are produced from chrome steel and are impervious to normal cleansing agents. The smooth surface of these air motors is easy to wash. The drives are so well sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or other options can penetrate the motor. The motors are even resistant to water penetration from commonly used cleaning spray methods. A wet surroundings is no concern for this motor. It may 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 discount of approx. 10-20% primarily based on the technical data stated in the product catalog ought to be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor have to boast different features for such applications?
Answer: Yes. In many purposes, condensation can type in air provide lines. It is subsequently advisable that measures are taken to guarantee that the motor just isn’t situated at the lowest level within the system and that it may be flushed out with water. Many users take precautionary measures, not only regarding the structure of the motor in their system, but also regarding using water separators or dryers in front of the drive. If เกจ์วัดความดัน is not potential, then we recommend a particular coating for those parts inside the motor’s interior that are created from chrome steel. This is because there is a restrict to the use of chrome steel for heavy obligation, high-speed internal components. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of where your motors can be utilized in the meals industry?
Answer: Stirring dough, moving and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade applications are endless. I’ll describe a couple of functions in more element, such as the usage 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 pace of seven hundred rpm.
We also have the perfect 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 63 mm.
Another software could be present in grinding mills and conveying techniques for grain processing. In this case, the main 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 find 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 wooden skewer through items of meat, onion and pepper. Pressure on 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 using an air motor: One of the primary benefits is its excessive 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 especially important when utilizing a handheld device but in fact also for robotic techniques the place the drive strikes with the robot arm.
Heat additionally leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of energy – it does not evaluate to the dangers of electrical energy. The power output from the air motor over extensive torque ranges is type of fixed. Air motors can subsequently be optimally operated in a wide field of fluctuating loads. There is no drawback with load being applied on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’ll run once more immediately and any variety of successive instances. Air motor energy may be tailored simply by adjusting the working stress. The velocity is lowered easily by throttling the air quantity. Throttling provide air is beneficial when torque also needs to be considerably lowered. Exhaust air throttling must be chosen to reduce speed with none severe affect on the torque.
Question: Air motors are sometimes seen to be less environment friendly in comparison with electric motors. Can you touch upon this statement?
Answer: Air motors and electrical motors can’t be compared on a one-to-one foundation. The efficiency of a drive at all times 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 utilized at reduced pace over an extended time period to safe the packaging tape. Electric motors cannot be loaded over an extended time frame with out working the danger of overheating. Therefore, for this packaging machine, an electric motor would want to resist high loads and in consequence would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You may choose an air motor with a nominal torque of 15 Nm and nominal speed of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs close to idle pace at 450 rpm underneath gentle load. The energy required for this air motor is subsequently solely 430W. The energy stability of an air motor is seen in a very totally different gentle when you consider that the air motor needed for this packaging machine would only require a 3rd of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on many years of experience in the area of air motors. They have a variety of excessive quality, globally well-liked industrial drive solutions. Are the ADVANCED LINE motors a special solution for meals industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our commonplace program has been adjusted to satisfy the needs of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers profit from long-established reliable drive options for the food business and medical expertise. We are in a position to provide these motors in a large energy range from 20 W to 1.6 kW combined with a variety of planetary gears from our own production with speeds of 7 to 24,000 rpm.
