Chapter 2 2.1.7.3.2 Field of application The technique is used, e.g. for drying coffee extracts, spices, soup vegetables, instant meals, fish and meat. 2.1.7.3.3 Description of techniques, methods and equipment The freeze-drying equipment consists of a drying chamber with temperature controlled shelves. This can be a batch chamber, where the trays remain fixed on the heating plates through the drying operation, or a semi-continuous type, in which the trays move through a vacuum lock into a drying tunnel. The equipment also includes a condenser, to trap water removed from the product in the drying chamber and to facilitate the drying process; a cooling system, to supply refrigerant to the shelves and the condenser, and a vacuum system, to reduce the pressure in the chamber. If the incoming product is a liquid, e.g. coffee extract, it is frozen in two steps, at two freezing temperatures and times, and then it is ground. The solid material is then fed manually or mechanically onto the trays in a drying chamber. The temperature of the drying chamber is well below 0 °C. The exact temperature depends on the product being dried. A vacuum is applied in the chamber. The ice evaporates under these conditions. This evaporation causes a further decrease in the temperature of the product, which is compensated for by adding heat by means of heating plates to the product through the temperature controlled trays. The evaporated water is refrozen on the surface of a condenser, which has a temperature well below the sublimation temperature under the existing conditions in the chamber. From time to time the condenser is de-iced by heating the condenser surface. The water is liquified and drained. The vacuum is maintained by a vacuum pump. The outlet of the vacuum pump is emitted into the air. To prevent solids entering and damaging the vacuum pump, a filter is usually applied in front of the pump. 2.1.8 Post processing operations (H) 2.1.8.1 Packing and filling (H.1) 2.1.8.1.1 Objective The objective of packing is to use any products made of any materials of any nature for the containment, protection, handling, delivery and presentation of goods. Packing may be applied to raw materials and to processed goods. Filling is the process of putting the product in the package in a proper way. 2.1.8.1.2 Field of application The majority of food products are packaged before they enter the distribution chain. In some cases packing is an integral part of the production process, which means that the packaged product is further processed. An example of this is the canning and bottling of foods and subsequent heat conservation. 48 January 2006 RHC/EIPPCB/FDM_BREF_FINAL
2.1.8.1.3 Description of techniques, methods and equipment Chapter 2 The European Parliament and Council Directive 94/62/EC [213, EC, 1994], states the following: Article 3 Definitions for the purposes of this Directive: 1. “packaging” shall mean all products made of any materials of any nature to be used for the containment, protection, handling, delivery and presentation of goods, from raw materials to processed goods, from the producer to the user or the consumer. “Non-returnable” items used for the same purposes shall also be considered to constitute packaging. “Packaging” consists only of: (a) sales packaging or primary packaging, i. e. packaging conceived so as to constitute a sales unit to the final user or consumer at the point of purchase; (b) grouped packaging or secondary packaging, i. e. packaging conceived so as to constitute at the point of purchase a grouping of a certain number of sales units whether the latter is sold as such to the final user or consumer or whether it serves only as a means to replenish the shelves at the point of sale; it can be removed from the product without affecting its characteristics; (c) transport packaging or tertiary packaging, i. e. packaging conceived so as to facilitate handling and transport of a number of sales units or grouped packagings in order to prevent physical handling and transport damage. Transport packaging does not include road, rail, ship and air containers; Most FDM products involve primary, secondary and tertiary packaging processes throughout the manufacture and distribution chain. The packaging materials used in the FDM sector are textiles, wood, metal, glass, rigid and semirigid plastic, flexible plastic films, paper and board. Textiles have poor barrier properties. Textile bags are still used to transport bulk products including grain, flour, sugar and salt. Wooden shipping containers have traditionally been used for a range of foods, such as fruits, vegetables, tea, wines, spirits and beer. Wooden containers were replaced a long time ago in some sectors, and are now increasingly being replaced everywhere by plastic drums and crates. Hermetically sealed, metal cans have high barrier properties and can withstand high and low temperatures. The materials used for metal cans are steel (tinplate or tin-free), and aluminium, but they may also be coated with tin or lacquers to prevent interactions with the foods within the can. Metal cans are widely used for soft drinks and beer. They are also used for canning sterilised foods, e.g. fruit, vegetables, condensed milk and meat products. Metal cans are recyclable. Aluminium foil is also widely used to pack several types of food. Glass has high barrier properties, is inert, and is suitable for heat and microwave processing. However, two disadvantages of glass are the weight and the risk of fracturing. Glass bottles and jars are widely used for milk, beer, wines and spirits, preserves, pastes and purées and also for some foods and instant drinks. Glass bottles and jars are re-usable and recyclable. Rigid and semi-rigid plastic containers include bottles, jars, cups, trays and tubs made from single or co extruded polymers. They are low weight, tough and unbreakable, easy to seal, have reasonably high barrier properties and great chemical resistance. Several techniques are available for the production of these containers, such as thermoforming, blow moulding, injection blow moulding, extrusion blow moulding and stretch blow moulding. Typical materials used are PVC (polyvinylchloride), PS (polystyrene), PP (polypropylene), XPP (expanded polypropylene, for thermoforming), HDPE (high density polyethylene), PET (polyethylene terephthalate), and polycarbonate. The containers are often made on-site. Some of the containers are re-usable, e.g. polycarbonate bottles for milk. Rigid and semi-rigid plastic containers are typically used for milk, soft drinks, dairy products, margarine, dried foods and ice-cream. RHC/EIPPCB/FDM_BREF_FINAL January 2006 49
