  • the raw material used to manufacture the food packaging trays 10 according to the present invention product is pure sugar cane reclaimed after the extraction of the sugar.
  • the manufacture of trays 10 follows a number of processing steps, as described below. In essence, the raw material (pure sugar cane reclaimed after the extraction of the sugar) is processed to form a pulp. The pulp is then introduced to moulds, which press the raw material to the required shape. The pulp is also rolled and compressed to create the former for the lids 20. After filling the compartment 14 with the various food product or products (not shown) , the food containers 10 and lids 20 are aligned in packaging equipment and are formed together using suitable heat and pressure .
  • sugar cane cultivated from plantations is transported to the manufacturing facility, and the sugar cane then processed into sheet form.
  • These sugar cane sheets are then pulverised into microparticles .
  • the pulverised cane is then added to a water-based solution containing additives for oil, chemical, and water resistance in finished product.
  • the raw pulp solution is stored in large silos which provide constant mixing.
  • a two-stage moulding process is utilised. The first stage of the process involves the pressurised extraction of the raw pulp solution from the silo. The pulp is then added to a precise volume of water in a moulding chamber which completely covers the metal mould profiles for whichever design is being manufactured.
  • the water is then expelled from the mould chamber leaving a uniform layer of pulp as the design profile.
  • This is possible by using a first tooling head formed as a wire mesh which allows the water in the solution to be extracted.
  • This pulp profile is then transferred to a second tooling head where controlled pressure and heat are applied to provide the finished product.

Abstract

La présente invention a trait à un procédé permettant de fabriquer un récipient de conditionnement d'aliments, à un appareil permettant de fabriquer un récipient de conditionnement d'aliments et à un récipient de conditionnement d'aliments produit selon le procédé. La présente invention a trait à un procédé et à un appareil permettant de fabriquer des récipients de conditionnement d'aliments dotés d'un opercule pelable à partir de pulpe de canne à sucre. Le récipient résultant est en mesure de contenir une variété d'aliments et est, après utilisation, entièrement biodégradable et compostable. Afin de fabriquer le récipient de conditionnement d'aliments, un processus de moulage en deux étapes est utilisé. En particulier, après l'introduction d'une solution de pulpe de canne à sucre à base d'eau dans une chambre de moulage, l'eau est ensuite extraite de la solution de pulpe de canne à sucre au moyen d'une première tête d'outillage maillée qui définit un profil approximatif du récipient de conditionnement d'aliments. Par la suite, le profil de pulpe de canne à sucre obtenu est alors transféré vers une seconde tête d'outillage et une pression ainsi qu'une chaleur appropriées sont appliquées.
