Pneumatics in food industry drives

Pneumatics in food industry drives

Pneumatics is an important component in the food industry, especially in beverage production. Thanks to its advantages such as reliability, versatility and ease of control, pneumatics are often used in various stages of the beverage production process.

In the case of beverage production lines, pneumatics are used in processes such as raw material handling, ingredient mixing, bottle or can filling, labeling and packaging. All of these processes require precision, repeatability and speed, and pneumatics are perfect for this.

An example of the application of pneumatics in the beverage industry is the bottle filling system. Pneumatic actuators are used to precisely position the bottles, e.g. SKY series guided compact actuators, and then fill them with the correct amount of liquid using ASCO process valves, for example. This makes the process fast, accurate and reliable.

The packaging of finished products is also worth mentioning. Pneumatic grippers such as the CPKB series of angle grippers are used to transfer bottles or cans to conveyor belts, and then to place them in the appropriate bulk packaging using, for example, the SKP series of compact rotation-protected cylinders. This makes the packaging process fast and efficient.

Compressed air transportation: the key to efficiency

Compressed air transportation plays a key role in the production processes of the beverage industry. Examples of effective use of compressed air transportation include:

  • Reducing energy losses: proper design and installation of compressed air conveying systems minimizes energy losses, resulting in lower production costs.
  • Reducing energy losses: proper design and installation of compressed air conveying systems minimizes energy losses, resulting in lower production costs.
  • Reduced downtime: regular maintenance and monitoring of compressed air conveying systems allows you to detect possible problems and solve them quickly, which minimizes production downtime. The use of appropriate compressed air dryers as well as regular monitoring of air quality allows to maintain the quality of production processes and minimize the risk of product contamination and failures.

Required quality of compressed air: standards and norms

In the beverage industry, the quality of compressed air is crucial to production processes. There are various standards and norms for compressed air quality, such as ISO 8573-1, which specify requirements for air purity, oil content, moisture content and particulate matter. By complying with these standards and norms, the quality of production processes can be maintained and the risk of product contamination can be minimized.

Compressed air drying: why is it important?

Compressed air drying is important for maintaining proper air quality in the production processes of the beverage industry. Improper compressed air drying can lead to negative effects such as:

  • Corrosion of devices: moisture in compressed air can corrode devices leading to damage and production downtime.
  • Product contamination: moisture in compressed air can lead to the growth of bacteria and mold, jeopardizing product quality and safety.
  • Increased costs: improper drying of compressed air can lead to increased costs for maintenance and repair of equipment and loss of products due to contamination.

The use of appropriate cyclone separators and refrigerated dehumidifiers, as well as regular monitoring of air quality, makes it possible to maintain the quality of production processes and minimize the risks associated with biological contamination of products.

Application of pneumatic actuators in the beverage industry

Pneumatic actuators, used in beverage production, are used for a variety of tasks such as bottle filling, labeling, and quality control. Thanks to their precision speed and reliability, pneumatic actuators help make production processes more efficient and maintain high product quality.

Types of pneumatic actuators and their applications

Various types of pneumatic actuators can be found in the beverage industry, such as:

  • SSI series pin linear actuators: used for rectilinear movements, such as lifting or moving parts. They can be used for filling bottles or cans and for labeling.
  • ARCTREG series rotary actuators: are used for rotary movements, such as turning components. They are used in component mixing or quality control systems.
  • Diaphragm actuators: used for precise dispensing of liquids, such as in the process of filling bottles or cans.

Pneumatic actuator installation: steps and tips

Proper installation of a pneumatic actuator is crucial to its proper operation. Some of the tips for proper of mounting pneumatic actuators are:

  1. Choose the right actuator: select the right actuator for the task, taking into account force, speed and range of motion requirements.
  2. Prepare the installation site: make sure the installation site is stable, clean and free of obstacles that could hinder the operation of the actuator.
  3. Install the actuator: mount the actuator according to the manufacturer’s instructions, use the appropriate fasteners, e.g. ball joints, ears, yokes, feet. Take care of proper connection to mechanical and pneumatic components. Don’t forget the appropriate connectors such as the 80.5092 series throttling valve couplings.
  4. Conduct tests: check the operation of the actuator by observing its movement and response to control signals. If necessary, make adjustments with throttle valves or dampers.

Actuator control: how does it work?

The operation of pneumatic actuators is controlled by special systems that control the flow of compressed air into the actuator. Examples of such systems are:

  • Electro-pneumatic valves of the ZMG series: electrically controlled, they allow precise control of air flow and the speed of response of an actuator.
  • TM series mechanical valves: controlled by mechanical motion, such as a lever or button, used in simpler applications.
  • AVENTICS proportional valves: allow infinite control of air flow, which allows precise control of actuator force and speed.

Advantages of pneumatic actuators in beverage production

The use of pneumatic actuators in food applications brings many benefits, such as:

  • High precision: pneumatic actuators allow precise motion control, which affects the quality of processes such as filling and labeling.
  • Speed and reliability: with fast response to control signals and low failure rates, pneumatic actuators contribute to production efficiency.
  • Ease of integration: pneumatic actuators can be easily integrated into existing control systems and other devices, allowing production lines to flexibly adapt to changing needs.
  • Product unification: when manufacturers’ standard solutions do not meet users’ expectations, it is possible to select devices while maintaining the existing mounting system.
  • Safety: compared to hydraulic cylinders, pneumatic cylinders are less prone to leakage. Their leaks are not associated with leaks of a potentially dangerous medium such as hydraulic oil, which translates into greater operational safety.

Pneumatic components and devices in the food industry

The food industry uses various pneumatic components and devices to improve production processes and maintain high product quality. Among them we can mention hoses for the food industry, check valves, or magnetic field sensors of the 17.10C4.01 series. It is worth noting the specifics of these components and their application in practice.

Tubes for the food industry: what you need to know

Hoses for the food industry must meet special requirements, such as resistance to high temperatures, chemicals and ease of cleaning. When choosing hoses, it is worth paying attention to the material from which they are made and their design. The hoses should be made of materials approved for food contact and have a declaration of conformity (DoC), such as polyurethane 80.0259.149/150, polyamide 80.0259.12 or Teflon 80.0259. It is also important that the hoses are abrasion resistant and easy to install and remove.

Valve solutions: check valves and other types

Valves used in the food industry perform various functions, such as controlling the flow of fluids or maintaining pressure in pneumatic systems. Among them are check valves, which prevent backflow of liquids; ball valves, which allow quick opening and closing of the flow; and Diaphragm valves, which are used for precise dispensing of fluids. The selection of the right type of valve depends on the specifics of the process and the requirements for control and regulation.
