Automated processes are standard apply in the meals industry. Production effectivity just isn’t the one motivation, hygiene additionally plays a key position in the food business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to meet these necessities and incorporate both these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is chosen to satisfy the excessive necessities for hygiene in the food industry, we normally recommend our ADVANCED LINE air vane motors. All their external elements are produced from chrome steel and are impervious to regular cleansing brokers. The clean surface of those air motors is straightforward to scrub. The drives are so well sealed with sturdy long-life radial shaft seals that no air can escape and equally no dust, water or other solutions can penetrate the motor. The motors are even immune to water penetration from generally used cleaning spray methods. A moist surroundings is no concern for this motor. It may even be used underwater as within the case of many stirring functions. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A power discount of approx. 10-20% based on the technical knowledge stated in the product catalog must be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast different options for such applications?
Answer: Yes. In many purposes, condensation can form in air provide traces. It is therefore advisable that measures are taken to ensure that the motor just isn’t situated at the lowest level in the system and that it might be flushed out with water. Many users take precautionary measures, not solely regarding the structure of the motor of their system, but additionally concerning the utilization of water separators or dryers in entrance of the drive. If all this is not potential, then we recommend a special coating for those parts inside the motor’s interior that are made from stainless steel. This is as a result of there’s a restrict to the utilization of stainless-steel for heavy duty, high-speed inside parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you 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 food trade functions are countless. I’ll describe a couple of applications 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 on the speed 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 energy within the smallest of spaces. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of 63 mm.
Another application may be present in grinding mills and conveying methods for grain processing. In this case, the focus is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably 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 wood 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 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 excessive power density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its dimension. This is particularly significant when utilizing a handheld gadget but in fact also for robotic methods where the drive strikes with the robot arm.
Heat additionally leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of power – it doesn’t examine to the hazards of electrical energy. The energy output from the air motor over wide torque ranges is type of fixed. Air motors can therefore be optimally operated in a large field of fluctuating masses. There is no downside with load being utilized on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After reduction of the load, it’s going to run again instantly and any variety of successive occasions. Air motor power may be tailored just by adjusting the working pressure. The velocity is decreased easily by throttling the air volume. Throttling supply air is recommended when torque also wants to be considerably decreased. Exhaust air throttling should be chosen to reduce pace with none severe affect on the torque.
Question: Air motors are often seen to be much less environment friendly compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. The efficiency of a drive all the time is dependent upon the conditions of the applying. 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 utilized at lowered pace over a long period of time to secure the packaging tape. Electric motors cannot be loaded over an extended period of time with out operating the danger of overheating. Therefore, for this packaging machine, an electrical motor would want to withstand excessive hundreds and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a very different story with the air motor: Due to the favourable 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 speed of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs near idle velocity at 450 rpm underneath light load. The energy required for this air motor is subsequently only 430W. The energy balance 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 reflect on decades of expertise within the subject of air motors. They have a extensive range of high quality, globally well-liked industrial drive solutions. Are เกจวัดแรง for meals trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our standard program has been adjusted to satisfy the needs of our prospects.
