Burkert's AirLINE Quick Provides a Flexible, Time Saving Solution for Pneumatic Control of Actuators in Hygienic Processes

Burkert’s new AirLINE Quick offers a reliable, compact and time-saving solution for the direct mounting of Burkert’s type 8640 valve islands and AirLINE 8644 automation system into control cabinets, eliminating the need for bulkhead connections and internal piping. Manufactured in a high-quality stainless steel version, and incorporating features such integrated exhaust check valves, the AirLINE Quick adapter allows an altogether smaller design of control cabinet for hygienic process actuation in the food, beverage or pharmaceutical industries.

The AirLINE Quick mounting system consists of an adapter plate integrated at the pneumatic connection of the AirLINE automation system. The adapter plate enables fast and easy mounting directly on the wall or floor of the control cabinet. An additional plate on the outside provides for added stability.
With AirLINE Quick, all pneumatic connections can be mounted directly on the control cabinet base or side eliminating the need for bulkhead connectors. Also integrated is the fieldbus communication and modular I/O for an altogether smaller design of control cabinets. Additional components such as pipes, cables or control cabinet connections are eliminated, due to direct mounting, further reducing the time needed for installation and commissioning.

For use in hygienic processes, the AirLINE Quick adapter plate and connections are available in a stainless steel (1.4301) version. However, for less critical applications, a lower cost anodised aluminium model is available, with pneumatic connections manufactured from nickel-plated brass.

The AirLINE Quick adapter is a complement to Bürkert’s valve terminals and automation systems, which are designed for use in many different areas of hygienic processes and readily fulfil the high standards of the market segment.

This compliance is ensured by the integrated process safety features of the type 8640 valve terminals and type 8644 automation system: features that are especially important in hygienic processes.

For example: check valves integrated in the exhaust air galleries ensure that during system emergency stop situations all actuators are shut down simultaneously and safely. These units also prevent back pressure accumulation in a valve block, which could result in unwanted switching of a valve, with serious consequences for the process. In addition, Burkert’s time-tested HotSwap function allows replacement of faulty valves, even during operation, without the risk of loss of air pressure on the entire valve block.

Can reliable distributed valve control be achieved retrospectively at a cost effective price?

The answer is an emphatic YES with Bürkert's retro-fittable valve controller for distirbuted or decentralised valve control or automation.

Distributed Control Valve :

Decentralised or distributed process control can bring with it many distinct advantages to optimising a plant design. Having valve switching and control occurring local to the valve can bring about many tangible benefits. These benefits can range from the cost reductions achieved through removing the need for centralised switching panels and the need for lengthy control and switching circuits, through to savings of compressed air and the faster switching response times of both valves and actuators. Operational constraints such as reliability and overall performance are nearly always achieved through a delicate balance with installation and operational costs, coupled with maintenance response times.

Whilst decentralise or distributed valve control is often a simple concept to address at the time of plant design and installation, the question is often asked; ‘how can it be successfully achieved after the event?’  - on an existing plant that has been constructed and optimised under a centralised control philosophy and is perhaps part way through its operational lifecycle?

Answer: Bürkert may have the answer in the form of its 8681 universal valve control head.

Burkert Valve Controller :

This is an intelligent valve control head or positioner that can be retrofitted to almost any manufacturer’s valve through a series of adaptors and kits that are readily available from Bürkert. This allows intelligent valve control to be applied local to the valve actuator at a fraction of the cost of a new valve controller assembly. It also significantly reduces the overall installation time. These retro-fittable controls heads have been optimised for applications within the food and beverage, pharmaceutical, brewery, dairy and personal health sectors. The valve controller heads already come with universal adaptors for many third party manufacturer’s valves already successfully deployed into these sectors, such as Alfa Laval, Definox, Kieselmann,  Aseptomag and many others.

Field Bus & Profibus Compatible :

The 8681 intelligent control head is compatible with many standardised communication and network protocols such as Fieldbus, Profibus, Asi and Devicenet and so will comfortably integrate with existing communication protocol installations. The controller is easy and inexpensive to install and is entirely non-intrusive. The valve position is determined automatically by a fast reliable intelligent function that makes use of an inductive analogue position sensor to determine valve position. The control heads come as standard with IP65/67 ingress protection and also provide an instant visual diagnostic facility for users.

As a design philosophy, decentralised automation of your plant process valves can provide a fast, economical and reliable improvement to your plant operation. The Bürkert 8681 universal valve control head can make those benefits retrospectively available to your operation with a cost effective, reliable and easy to install modular solution.

Bürkert improves control of water oxygenation

Bürkert Fluid Control Systems has developed an innovative solution for the oxygenation of raw drinking water. Available in a range of sizes to suit industrial and commercial water improvement schemes, the Oxydatorbox is designed to automatically measure water flow and control oxygen levels accurately and efficiently.           

Water purity is a key factor in a number of industrial processes on sites such as breweries, fish farms and drinking water production. Oxygen is, amongst other things, used for oxidation of the dissolved iron in the raw water. The highly dissolved iron Fe2+ is oxidized to produce the much less soluble Fe3+. This leads to auburn deposits in the raw water which can then be easily filtered to fulfil the drinking water requirements.

The Oxydatorbox is designed to control the airflow, independent of pressure, via a Bürkert mass flow controller (MFC), type 8626, which is a compact system consisting of a flow sensor, a controller and an actuator. The MFC is configured using the software supplied, which can also be used for diagnosis and communication with fieldbus systems such as Profibus and Devicenet. This extremely flexible system allows target points to be set as well as read from a remote station.

The incoming air pressure is controlled by a pressure regulating valve, with a secondary valve designed to protect the Oxydatorbox from back pressure in the event of a loss of air pressure. There is also an option to have a solenoid valve, designed with a slow opening characteristic for opening the air inlet safely via an external signal. The control system can be configured for use with air or pure oxygen, depending on the process requirements.

The Oxydatorbox is available in 3 different sizes and can be constructed from GRP, steel or stainless steel, depending on the plant requirements, and is protected to IP56. The air pipe fittings are available in ¼”, ½” and ¾” as standard but other options are available on request. Options such as quick air-vent valves, power supplies and flow rate transmitters are also available.

This packaged problem solving solution from Bürkert is designed to provide flexibility, but essentially to save time and costs compared to a fully bespoke solution, making it compact, cost effective and easy to apply in order to achieve reliable and extremely accurate performance.

All process control solutions, including the Oxydatorbox, are designed in-house by Bürkert using the latest 3D SolidWorks software and electrical design software. Every product is designed to meet the client’s exact requirements and is assembled and fully tested before dispatch. Bürkert service technicians are also available to assist with the installation and commissioning of the system.

Burkert’s 8175 Ultrasonic Level Transmitter Offers Level Measurement up to 10-metres Across Complex Tank Shapes



Open Channel Flow Measurement



Burkert’s Ultrasonic Level Transmitter Type 8175 provides continuous level measurement at distances up to 10-metres. Integrating an ultrasonic sensor and a transducer with a large 8-digit multi-language display in a splash-proof IP65 or immersion-proof IP67 housing, the Type 8175 offers users a teach-In function for easy commissioning, and also delivers low total cost of ownership.

Designed for use in water treatment, pharmaceutical, food and other hygiene-based industries, the 8175 is a non-contact filling level transmitter that can be used in both open and closed vessels.



Simple to use, with its menu-guided operation and 8- digit alphanumeric display, the Type 8175 delivers fast and easy commissioning with its integrated “Teach-In” and “Simulation” functions. These allow different tank shapes (cylindrical, cubic, spherical) to be easily programmed via fixed default shapes, or at complex tank shapes step- by- step. Importantly, the simulation functions allow the system to be tested under dry-run conditions, and the resulting measured value can be shown as a level, a distance (in cm, m, inch or feet), or direct, as a volume (litre, m3, Imp. gal or US gal).



Solid Level Measurement



Underpinning its reliability in continuous process environments, the Type 8175 integrates a range of fail-safe features, including signal loss, power supply failure, and level or temperature alarms, which can be activated with an adjustable time delay. In addition, a range of filter functions control the return echoes and automatically eliminate all interference due to elements of the vessel.

Application of TYPE 8175 : 

A high frequency ultrasonic sound wave is pulsed eight times per second from the base of the transducer. This sound wave reflects against the process medium below and returns to the transducer. The  microprocessor measures the time of flight between the sound generation and receipt, translates this figure into the distance or volume between transmitter and process medium below.

What is Cleaning in Place? How Does it Work and Where Burkert Solutions would be ?

                                                                          

Cleaning in Place (CIP) has been around for approximately 50 years, and is commonly used in hygiene critical industries, such Food, Beverage and Pharmaceutical, to clean a wide range of plant. CIP refers to the use of a mix of chemicals, heat and water to clean machinery, vessels or pipe work without dismantling plant. The process can be one shot, where everything goes to drain, or recovery, which recycles most of the liquid. Overall, CIP can be a very efficient way of cleaning.

The principles of CIP can be applied to any industry and plant where hygiene is critical; and the process is usually an integral part of any automated plant. Increasing Health and Safety legislation is set to make CIP more common, which is a good thing because a shiny surface on the outside of plant is no guarantee of cleanliness on the inside.

CIP is principally concerned with soil removal: soil being anything that should not be present in a clean vessel. Soil can cause tainting and can often be smelt. It can be visible (scale, foreign bodies,) or invisible in the form of bacteria, such as E Coli, or Yeast spores. The time needed to remove soil is at least 15 minutes using a suitable chemical (strength dependent on chemical supplier and product) at temperatures above 50 degrees C, but no greater than 75 degrees C because there is no advantage to be gained above this temperature.

CLEANING AGENTS

Commonly used chemicals for soil removal include Caustic Soda, Phosphoric and Nitric acids, Sodium Hypochlorite (Hypo) and Peracetic Acid (PAA). Caustic Soda is an alkali typically used at 0.5% - 2% volume. It reacts with the fats in the soil and softens it for removal. One downside is that Caustic Soda is not effective for removing scaling. In addition, sequestriants are often added to keep soiling in solution.
Phosphoric and Nitric Acids are used in detergent formulations for scale removal, often at lower temperatures than Caustic. These acids must be used with care as they can attack valve and pump seals. They are often used in dairies for one week in every 6 weeks to remove milk scale, and can be used after commissioning to remove installation debris.

Sodium Hypochlorite (Hypo) offers the advantage of a very low cost. It is used primarily for disinfection because its ability for soil removal is poor. The active ingredient of Hypo is Chlorine (Bleach). This can corrode Stainless Steel in high concentrations and will attack seals and personnel. It will also taint if not rinsed out; and is dangerous if mixed with acid, forming Chlorine gas, which is poisonous.
PAA is an equilibrium mixture of acetic acid and hydrogen peroxide. It is a powerful oxidising agent with an oxidation capacity higher than sodium hypochlorite and chlorine dioxide, and is comparable to the oxidative capacity of ozone. PAA at 75 mg/L is reported to successfully kill 100% of a 10(7) cell/ml yeast or bacterial population in 30- seconds.

CIP Line & Vessel Cleaning
             
                          

When cleaning lines in process equipment using CIP, the correct fluid velocity must be achieved to obtain good cleaning. Laminar flow, from velocities below 1.5m/sec does not give good cleaning characteristics. What is required is turbulent flow at velocities between 1.5-2.1 m/sec. There is no gain at velocities above 2.1 m/sec.

In the cleaning of vessels two main methods are generally employed. The first uses high pressure cleaning heads to remove soil by mechanical action: the vessel surface being contacted in a series of passes. The second method employs low pressure cleaning heads that rely purely on chemical action to remove the soiling.

CIP Return

The majority of problems with CIP can be attributed to poor CIP return. This causes excessive CIP times, excessive use of detergent and heat with high effluent discharge.

To overcome these problems the system for Return must quickly and efficiently return the cleaning solutions back to the CIP Set. Critical in this respect is the choice of scavenge pump.
Poor scavenge allows back up of cleaning solution and poor cleaning of the lower part of the vessel. In contrast, effective scavenge allows fresh cleaning solutions to contact the vessel walls and carry away soil effectively.

CIP Optimisation

                                                                  

Most CIP sequences are never altered from post installation settings; these are usually a set of “defaults” which are set on commissioning. However CIP operators can optimise their systems by monitoring a number of key parameters. These are:

• What temperature and concentration (conductivity) are the Caustic tanks set to? - often set too high with no added benefit.
• Consider the Pre-Rinse – does it run clear and then keep going?
• Caustic Fill – how high are the Return Conductivity and Temperature Transmitters set?
• Intermediate Rinse – is it removing caustic solution and temperature prior to sterilisation?
• Sterilisation – what strength is the sterilising agent and how long is the contact time?
Finally all changes resulting from the CIP monitoring process should be documented and validated to meet any statutory regulations, and/or specific client requirements.

New multiCELL Transmitter/Controller Provides Single Unit for Measurement of Flow Rate, pH, Temperature & Conductivity

                                                                               

mutiCELL TYPE 8619



Burkert’s new type 8619 multiCELL transmitter/controllers are designed to cut processing costs in water treatment and hygienic processing applications, providing one device for the direct connection of a wide range of sensors to measure parameters such as flow rate, pH, ORP, temperature and conductivity.

The multiCELL multichannel transmitter/controller fits a standard ¼ DIN cutout to provide an IP65 fascia; it is a highly versatile analysis measuring system for diverse areas of application, including water treatment, foodstuffs and pharmaceuticals. It comprises a fully-featured basic modular unit equipped with a large backlit display, user-friendly softkey controls, two digital and frequency inputs, direct connections for various sensor types and two digital and analogue outputs that drive solenoid valves, control valves and actuators, such as dosing pumps.

The high level of functionality included in the basic multiCELL unit can be expanded easily, by adding hardware and software modules. Depending on signal requirements, up to six pre-configured I/O boards can be added, and software packages can be installed for further enhancements of the transmitter functions. In addition, the versatile multiCELL can also be configured as a Multipoint data logger with data storage on SD cards.

                      

The advantage of this modular expansion facility is that multiCELL users pay only for the features that they actually require. Moreover, since the multiCELL provides a single transmitter across a wide range of applications, inventory and training costs are both minimised.

The multi-channel multiCELL is ideal for a wide range of applications in ‘water treatment’. These include: cooling towers; drinking water monitoring; the production and monitoring of ultra pure water; verifying the water quality in desalination processes of reverse osmosis plants, using pH, conductivity and flow sensors and in bio reactors, where pH, ORP and temperature measurements and control are requested.

                                                            

In the area of Hygienic Processing, multiCELL is the right choice for CIP applications that require the direct connection of pH, ORP and temperature sensors, as well as analogue outputs for process monitoring. In this, and in all applications for which the multiCELL is designed, the built-in menu navigation remains transparent, intuitive and tolerant to operators’ mistakes despite the substantial functionality of the device – with values only accepted after following a confirmation input.
