1. INTRODUCTION
These are the original instructions and not a translation of the operation and maintenance of the
GTR machine.
This manual describes the Proseal standard GTR rotary table heat sealing system. The machine
automatically gas flushes the tray cavity whilst it cuts and seals coated reel fed film onto pre-formed
filled trays. The machine may also be supplied as a GTR-B version which is designed to seal pre-
formed board trays with pre-cut lids. In this mode the film feed and rewind assemblies will have
been removed.
The machine has been cleaned to a satisfactory engineering standard prior to dispatch. It is your
responsibility to ensure the machine is cleaned to the relevant food hygiene standard prior to
production.
All Proseal machines are designed and constructed using materials which are safe to use in the
food processing environment. Consideration has been given during the design of the machines to
reduce the risk of product spills and to ensure they can be cleaned easily and effectively.
Safety interlocked doors are provided enabling enclosed areas to be accessed for cleaning.
The operation of Proseal machines means they do not come into direct contact with food products
Components such as bearings; belts pneumatic and electrical components are industry standard
approved components for use in the food production environment.
Any lubricants used on the machine are foodsafe grades.
To ensure your Proseal machine remains hygienic, correct maintenance procedures should be
followed and any defective parts should be replaced
The correct cleaning of your Proseal machine is also vital.
1.1 Materials
Below is a list of materials used in the construction of a Proseal machine:
• 5083 Anodised Aluminium
This material is widely used in the machine construction. The aluminium is anodised to minimise
corrosion when strong cleaning fluids are used in the cleaning of the machine.
• 5083 Hard Anodised and PTFE Coated Aluminium
This material is used in areas where the part is subject to contact with moving parts of the machine
such a conveyor belt support plates.
• 304 Stainless Steel
This material is used the construction of all the enclosures; conduits and guarding of the machine. It
is also widely used for components and structural parts of the machine.
• 304 A2 Stainless Steel Fasteners
• All fasteners used on the machine are A2 (304) grade.
• Engineered Plastics
• Various plastic materials are used on Proseal machines such as Acetal; polyurethane; HDPE.
