Automated processes are normal follow in the meals business. Production efficiency just isn’t the one 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 tips on how to design a drive to meet these necessities and incorporate each these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to make certain that the proper drive is selected to fulfill the excessive requirements for hygiene in the food business, we normally recommend our ADVANCED LINE air vane motors. All their external elements are made from stainless-steel and are impervious to regular cleaning agents. The clean floor of these air motors is straightforward to clean. 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 solutions can penetrate the motor. The motors are even immune to water penetration from generally used cleaning spray systems. A wet environment is not any concern for this motor. It can even be used underwater as within the case of many stirring applications. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and could be operated oil-free. A power reduction of approx. 10-20% based on the technical data said 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 features for such applications?
Answer: Yes. In many purposes, condensation can type in air provide traces. It is subsequently advisable that measures are taken to make certain that the motor is not situated at the lowest point in the system and that it can be flushed out with water. Many customers take precautionary measures, not only referring to the structure of the motor of their system, but also regarding the use 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 inside the motor’s inside which are created from chrome steel. This is as a result of there’s a limit to the use of stainless steel for heavy responsibility, high-speed inner elements. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you have any examples of where your motors can be used within the meals industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business purposes are countless. I’ll describe a couple of applications in more element, corresponding 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 velocity of 700 rpm.
We also have the ideal drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of spaces. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a starting torque of 585 Nm and has a most diameter of 63 mm.
Another utility could be found in grinding mills and conveying systems for grain processing. In this case, the main target is on dust era 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 in 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 wooden skewer via pieces of meat, onion and pepper. Pressure on the skewer is 38 kg and due to this fact 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 primary benefits is its excessive energy density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a 3rd of its dimension. This is especially vital when utilizing a handheld gadget however in fact also for robotic techniques the place the drive strikes with the robotic arm.
Heat also leaves the air motor cold. In critical settings, compressed air is an unproblematic source of vitality – it doesn’t examine to the hazards of electrical energy. The energy output from the air motor over extensive torque ranges is kind of constant. Air motors can subsequently be optimally operated in a wide field of fluctuating loads. There is not any problem with load being applied on the air motor till standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it’s going to run again immediately and any variety of successive occasions. Air motor power could be tailored simply by adjusting the working pressure. The velocity is lowered easily by throttling the air volume. Throttling supply air is beneficial when torque also needs to be considerably reduced. Exhaust air throttling must be chosen to reduce velocity without any serious affect on the torque.
Question: Air motors are often seen to be much less environment friendly in comparability with electrical motors. Can you touch upon this statement?
Answer: Air motors and electrical motors can’t be compared on a one-to-one basis. The effectivity of a drive all the time is determined by the situations of the applying. Let me use this instance to clarify: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at lowered speed over a protracted time period to secure the packaging tape. Electric motors can’t be loaded over an extended time frame without running the chance of overheating. Therefore, for this packaging machine, an electric motor would need to resist high hundreds and consequently would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely different story with the air motor: Due to the favourable torque characteristics of air motors, a lower-powered drive will suffice. You might choose 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 close to idle velocity at 450 rpm under gentle load. The energy required for this air motor is due to this fact solely 430W. The vitality balance of an air motor is seen in a totally completely different light when you consider that the air motor needed 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 in the area of air motors. digital pressure gauge have a broad range of excessive quality, globally popular industrial drive options. Are the ADVANCED LINE motors a particular solution for food industry 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 customers.
