Food Process Industry

Parsons have been supplying equipment and services to the food since 1969. The equipment like the industry is varied and covers many aspects here are a few listed

	Polypropylene Wall Cladding for the Meat Processing and Abattoir Industry		Odour Abatement and Process Ventilation for Poultry Processing Plants
	Fermenting Vessels for the production of Cider Vinegar		Pure Water Storage Vessels
	Polypropylene lining of wooden mixing/fermenting vats for the Brewing Industry		Conveyor Guards and handling equipment for the Chocolate process Industry
	Cleaning In Place (CIP) Chemical storage/mixing and distribution systems.		Pet food production ventilation systems and Odour Abatement schemes.
	Vessels manufactured from Polypropylene for the soft drinks industry		Ventilation and Odour Abatement for Tobacco Production
	Carbon Dioxide De-aerators for the carbonated drink industry		Catalytic and Multi Stage Chemical Scrubbing Systems for the Odour Abatement
	Mixing and storage Vessels for the foods processing such as Jams, sauces and chutney.		Effluent Treatment upgrades and optimisation
	Blood Storage and Ventilation Systems		Meat Rendering Odour Abatement Scheme
	Chemical Storage Facilities including complete solutions for the bulk Storage of Hydrochloric Acid and Caustic Soda used in water treatment and effluent treatment as well as many other corrosive chemicals which demand specific engineering consideration.

Parsons undertake total engineering responsibilities cover all aspects of the project:
	Front End Design Study		Civil Requirements
	Process Engineering		Site Surveying
	Scrubber Design		Construction Management
	Exhaust Ductwork		Installation
	Fan Selection		CDM Compliance
	Discharge Stacks		Commissioning
	Supporting/Access Steel Structures		Documentation
	Jobside and Atmospheric Attenuation Requirements/Noise Studies		Handover

The above list details the full services offered by Parsons and the client can select which elements they wish Parsons to provide and which they prefer to resource in-house, clear identification of responsibilities at an early stage of a project ensures project completion on time and on budget.

Parsons are equally experienced on Greenfield site projects, or replacement of existing equipment within a working production facility, both represent challenges. The importance of accurate site surveying is just as important in all cases.

Parsons utilise state of the art “All Station” laser measuring devices, which are used by experienced engineers who then download the information into a 3D AutoCAD image that forms the basis of the design. Once the site survey has been completed the normal mechanical and process engineering procedures are undertaken to produce manufacturing drawings, during manufacture in Parsons factory the vessels are regularly inspected and dimensional laser checks are carried out and overlaid onto the site General Arrangement Drawings to ensure accurate interfacing.

The Scrubbing vessels tend to be manufactured from 6mm PP reinforced externally with GRP; various resin systems are used to accommodate process design requirements in respect of heat distortion and chemical resistance. In certain cases PP is not recommended and so as alternatives Parsons offer PVDF, ECTFE, FEP and PFA although these materials tend to be thinner.

Parsons have developed considerable expertise in all materials including pure Furane GRP moulded construction.

Generally system pressures fall in the range of 1000 Pa to 6000 Pa and so corrosion resistant fans form an integral element of the system, Parsons manufacture a full range of corrosion resistant fans.

Small scrubbing packages can be skid mounted, which enables the scrubber to be installed within a coated mild steel framework giving access to all parts of the scrubber for the purpose of maintenance. The recirculation pumps, pipe work, ductwork, instrumentation and control panels are all mounted within the skid, fully installed and tested in our works so that all commissioning can be done off site. This facility reduces cost and installation times on site and is a design option that has been used many times by clients both in the UK and Overseas.

On larger scrubber installations Skid mounting is not practical however Parsons have lead the way in skid mounted Recirculation systems which again minimises site installation time and cost.

Plastic Ductwork systems can be quite complex on larger Chemical Processing site’s and reliable flow control and isolation are demanded for safe plant operation Parsons manufacture a full range of manual and actuated dampers for flow control and isolation purposes to complete their ductwork programme. The ductwork programme ranges in size from 110 mm diameter up to 3000 mm diameter is available in PVC or Polypropylene reinforced where required with GRP, a range of corrosion resistant attenuators and stacks completes the complete system.

Parsons who manufactures a wide range of plastic storage vessels and reactors also caters for the storage and processing of chemicals.

Vessels are manufactured from:
	PVC
	Polypropylene
	Acrylic
	PVDF
	ECTFE
	FEP
	PFA reinforced externally where required with GRP in accordance with BS 4994-1987 other standards such as ASME X and DVS 2205 are also available on request.

Vessels are available in rectangular/square styles in complete or sectional design, where space or processes prefer circular vessels up to 4.5 metres diameter 18 metres tall can be produced. Circular vessels tend to be vertical axis but if preferred Parsons can supply Horizontal axis vessels complete with support cradles. Full delivery, installation and commissioning services are available using our own experienced site technicians supervised by our Qualified Engineering Staff.

Vessels are available with a wide range of accessories:
	Totally enclosed or lids		Contents Gauges
	Man way Entrance Points		Heaters/Heat Exchangers
	Hold Down Feet		Lagging
	Lifting Lugs		Access Ladders
	Nozzles		Tanker Filling Pipework
	Discharge Pipework/ Metering/Distribution Systems		Storage Bunds
	Remote Alarm Systems
