Ideally suited to product development purposes, the Armfield FT111 Laboratory-scale Rapid Extractor is used to extract the active constituents from materials in laboratory-scale batch sizes.

Armfield FT140 Multipurpose Mixing Vessels are designed and constructed using high-quality hygienic industry standard materials. These tanks are available in three models in varying configurations (see table) and are available in 50l and 100l volumes. All three models have an internal surface made of AISI 316 stainless steel.

The Armfield FT141 and FT142 are versatile batch processing vessels, the FT142 having UHT capability. They are suitable for high shear mixing, dispersing, homogenising, emulsifying, evaporation and vacuum deaerating.

The Armfield FT17 is a lab-scale system for evaluating membranes in a cross-flow filtration application enabling rapid determination of cross flow filtration performance using a range of membrane types with small product volumes (1 litre). It can also be used in teaching applications to demonstrate features of different membrane types and the effect of varying filtration variables.

The FT174X is a modular HTST/UHT processing system designed to treat products at flow rates of 12-40 l/hr or up to 60 l/hr for water (or similar low viscosity products). Standard modules for direct heating (steam injection) or indirect heating (using tubular and/or plate heat exchangers), aseptic processing, upstream or downstream homogenisation and additional chilling are available. These, along with many other options, enable multiple modules to be included in the same system, giving high process adaptability by reconfiguration of flexible product hoses, using quick-release connections. The sterilisation options enable it to be linked to an Armfield sterile filling bench to produce aseptic product, even when using long holding tubes and/or downstream homogenisation. As with all Armfield systems, it comes with hygienic fittings throughout as standard, it is easy to clean and very flexible in use. The touchscreen control panel makes it extremely user friendly to configure and monitor processing parameters. The operator is prompted at every stage whenever intervention is required.

The Armfield FT18-MkII is a small pilot-scale cross-flow filtration system designed to operate with a range of membrane module configurations. It can operate with as little as 5-10 litres of material but still give data that is useful for process scale-up. It can be used over the full range of cross-flow filtration applications from microfiltration through to reverse osmosis. It is the perfect tool to use, following on from flat sheet membrane trials with the FT17, for further process development and scale-up.

The Armfield Cheese Vat is designed to provide practical training in the production of cheese by the traditional method. The Armfield Cheese Vat makes an ideal research facility. When making Cheddar type cheese, approximately 1kg of cheese is produced from a ten-litre batch of milk.

The costs incurred by the length of time taken, the large quantities of raw materials required and the interruption of the production process mean it is disadvantageous to test new products using full-scale production equipment. The Armfield evaporator processes samples as small as two litres under conditions identical to those in production, sufficient to reveal the effect of heating on any ingredients newly introduced to the recipe. As well as investigation of the effect on organoleptic and physico-chemical properties, the equipment can be used to prepare product for taste trials on a daily basis to ensure the quality of incoming raw material is consistent.

Armfield miniature-scale technology is well established as offering developers the opportunity to run small trials, which provide enough information to enable scale-up to larger plant with confidence. The formulations go through similar physio-chemical changes as they would in production plant and real time data logging permits results to be recorded and repeated. The FT25 range of miniature-scale scraped surface heat exchangers has built in control and flexibility with a graphic representation on the membrane technology control panel. The operator can choose the parameters wanted for any particular formulation. The FT25 has a number of configurations according to the use required.

The CentriPeel centrifuge is a basket type separator, designed to save time in R&D operations. The FT27 can be operated at up to 400g, reducing the hours typically required for gravity setting a liquid to just a few minutes. The all stainless CentriPeel centrifuge is a solid bowl type separator designed to save time in R&D operations. It has a capacity of nine litres per batch and can be operated at up to 400g. It thereby reduces the several hours typically required for gravity setting a liquid to just a few minutes and also gives much improved separation.

The FT29 is a batch process unit suitable for teaching and research. Capable of a variety of solid/liquid extractions, it is particularly suitable for leaching edible oils from seeds and desolventising extracted solids and miscella. The Armfield Batch Solvent Extraction and Desolventising Unit is a floor-standing, batch-process unit capable of carrying out a variety of solid/liquid extractions. It is particularly suitable for ‘leaching’ edible oils from oil-bearing seeds and desolventising both the extracted solids and the miscella.

A vital stage in the preparation of a food product is the accurate addition and correct mixing of the various ingredients that make up the recipe. It is usual that heat will be required, subsequent cooling and chilling are often needed for preservation. The Armfield Multi-purpose Processing Vessel is able to carry out these actions with very small quantities of ingredients. The facilities to mix, emulsify, heat, pasteurise, incubate, cool, chill and cure are all built into this purpose-designed unit. As well as preparation of food products for further processing, the facilities allow production of finished products in batch sizes from five to 20 litres.

The Armfield FT51 deaerator unit has been designed to enable small quantities of food and other liquid products to be processed conveniently in the laboratory. It can be used as a standalone batch deaerator or inline with one of the Armfield continuous processing systems, such as the FT74XTS or the FT174X. The unit is designed to mirror the industrial processes of vacuum deaeration.

The Armfield FT52 has been designed to provide additional cleaning performance for Armfield FT units and other equipment. It consists of a high flow rate stainless steel centrifugal pump mounted on a mobile frame.

The Armfield FT66 Neutraliser/Washer/Bleacher is a floor-standing batch processing vessel capable of performing the pre-refining stages on small quantities of crude edible oils and facilitates practical research and development.
