Spray nozzles for the food and beverage industry

Spray technology forms a vital part of many food manufacturing processes. SNP have the product range and expertise to support all key food processing spray applications. Whether it be precision coating nozzles, CIP cleaning heads or the delivery of sanitising sprays we have high quality nozzles of all types backed by up decades of product experience. This means that no matter what the application we are able to offer sound advice on the correct spray set-up.

Key spray applications for the food & beverage industry

The uses of spray nozzles in the food industry are varied and diverse but the following applications are given attention in this section of our web page: spray coating; tank cleaning (CIP); cleaning and washing; and sanitisation nozzles and systems for food processing facilities.

See our Food Industry brochure (right) for full details of our spray solutions for the food and drinks sector which also include solutions for spray drying, pasteurisation, freezing and deluge cooling and mixing.

Spray coating

Typically, flat fan nozzles are used to deliver a variety of coatings. Accurate and precise spraying is the key driver so air actuated and/or air atomised nozzles are often used.

Tank cleaning

Rotary jet cleaners A huge variety of tanks and vessels need to be cleaned regularly in many food and beverage manufacturing process lines. SNP have tank cleaning heads suitable for small barrels up to large storage silos and anything in between.

Please click here or on the blue menu to the right to access more detailed information on tank cleaning nozzle selection for the food industry. Alternatively you can access the tank cleaning data sheets by clicking the boxes below.

Cleaning and washing

Hygiene is clearly very important in any food processing system. Outside of tanks and vessel cleaning (see above) a wide range of products and parts need to be kept clean via directed spray nozzles. See our brochure (right) for our full Cleaning and Disinfecting brochure.

Sanitising

Nozzles for sanitising

Sanitising fogs and mists are commonly used to kill microbes after residues have been removed by cleaning. The sprays used are very fine and are designed to move everywhere within a confined space to ensure complete sanitisation.

IBC Cleaning System

SNP's IBC Cleaning System station is a complete solution for cleaning intermediate bulk containers (IBCs) in-house. Where 5-50 IBCs need to be cleaned per week, the IBC cleaning station solution saves time, money and water.

The cleaning of IBCs is a common application in many industries. Often, specialist external companies are used to take away and clean IBCs or companies may clean them manually in-house. The IBC Cleaning Station system from SNP allows for the quick, safe and effective cleaning of IBCs in house.

This system consists of:

A powerful tank cleaning head. Either a rotary jet cleaner (Orbitor Eco) or a spinning tank cleaner (RSB25)
A variable speed pump
A specially designed positioning arm that holds the tank cleaner in place and fastens to the IBC lid
Hose and connectors

Operation

The IBC cleaner is incredibly simple to operate. In 5 steps almost any residue can be cleaned in a matter of minutes or even seconds.

Simply screw the positioning pipe onto the IBC lid
Connect to the pump
Connect the pump to a suitable water supply
Turn on the pump
Turn off when the IBC is clean

Cleaning and washdown systems for sanitising food processing facilities

In addition to our range of spray nozzles for sanitising we also offer a wide range of cleaning and disinfecting solutions for food processing and manufacturing plants. These include mixing stations and guns which will mix cleaning chemicals with a mains water supply either at a wall mounted unit, at the guns or via a trolley based cleaning unit as well as equipment for spraying, foaming and fogging. The Lafferty range of sanitising and washdown systems can be deployed in almost any food production facility.

Foaming

Foaming agents introduced into a washdown system will help improve the dwell time of cleaning chemicals. This improved action time often means less chemicals and water can be used to achieve the same levels of cleanliness. The Lafferty range of foam units can be used with just water or water and compressed air. They are available as wall mounted systems, trolley mounted or will mix at the spray gun itself. For more infomation, visit our Foaming Products page here.

Mixing Systems

The accurate mixing of washdown and sanitising chemicals is an important part of the overall cleaning process in any food factory. Our venturi mixing systems allow for the acurrate mixing of chemicals with no pumps or external power required. They are a simple, accurate and rapid way to mix cleaning fluids with mains water.



Spraying
We have a range of mobile and wall mounted spraying systems.



Fogging
Fogging systems provide a disinfectant mist to kill pathogens both in the air and on surfaces. We supply mobile and stationary fogging solutions as well as a range of fogging guns (see here for more details of our fogging guns).

Key spray engineering challenges

There are many challenges that need to be overcome to deliver successful spraying applications in the food industry. Four key challenges are discussed in these web pages.

Spraying viscous fluids

The food industry uses a variety of different coatings and liquids that are highly viscous. These fluids have very different properties to water and as such can present significant challenges when it comes to successful spraying. SNP have both the product range and application knowledge to meet these challenges.

Please click here or on the grey menu to the right to access more detailed information on meeting the challenges of spraying viscous fluids.

Strict hygiene standards

We manufacture nozzles in food grade 316 stainless, PTFE and PVDF as standard. With options of hastelloy and other higher-grade alloys where required. Our nozzle manufacturing process is backed up by ISO standards, full material certs and documented quality processes to meet the strictest of requirements. This means that you can be assured of a high quality product that will meet the stringent needs of the food industry.

Please click here or on the grey menu to the right to access more detailed information on meeting strict hygiene standards.

Precision spraying

The perishable nature of the product and strict safety standards mean that any process failure can be result in significant financial losses. The cost of a lost batch due a faulty spraying system will often dwarf the cost of the spray nozzles involved. This is why it is vital to talk to experts like SNP’s sales engineers. Our entire business is built on expertise in spray nozzles. We can offer the correct advice on nozzle selection so your process will work as intended.

Water efficiency

The food industry uses vast amounts of water. This represents a significant cost to many food processing businesses. Saving water is thus a critical concern for many plant managers. Correct nozzle selection can optimise spraying systems meaning the same job can often be performed with less fluid. The financial benefits of spray process optimisation can be significant and this is particularly true in tank cleaning applications. SNP have both the product range and applications knowledge to advise on any such optimisation projects.

In a similar vein, nozzle selection can be critical in optimising the use of coating products such as egg glazes. Over-spraying or using sprays that are not optimally atomised can result in product waste and inefficiencies. Again, SNP have the product and application knowledge to help minimise such wastage.
