Abstract

An apparatus, and a system for manufacturing a bioplastic material from a blend solution of gum arabica (GA) and polyvinyl alcohol (PVA) is provided. The apparatus includes a panel having a first end, a second end distal to the first end, and a plurality of walls extending from a periphery of the panel, the panel configured to accommodate the blend solution. The apparatus further includes a plurality of support members coupled to the first end and the second end of the panel and configured to adjust a slope angle of the panel; and one or more vibration generating units coupled to the plurality of support members and configured to vibrate the panel when the blend solution flows from the first end to the second end of the panel. A method of preparing the bioplastic material is also disclosed.

First claim

The invention claimed is:

1. A system for manufacturing a bioplastic material, the system comprising:
a cold air supply unit;
a vacuum pump; and
an apparatus fluidly coupled to the cold air supply unit and the vacuum pump, the apparatus comprising:
a panel having a first end, a second end, an inlet configured to fluidly couple with the cold air supply unit, an outlet configured to fluidly couple with the vacuum pump, and a plurality of walls extending from the first end, the second end, the panel configured to accommodate a blend solution of gum arabic and polyvinyl alcohol;
a plurality of support members coupled to the first end and the second end of the panel and configured to adjust a slope angle of the panel, wherein the slope angle is defined between a plane of the panel defined by the first end and the second end thereof and a horizontal plane;
one or more vibration generating units coupled to the plurality of support members and configured to vibrate the panel when the blend solution flows from the first end to the second end of the panel; and
a filter having a dehydrant stored therein, the filter configured to fluidly couple with the inlet to supply the dehydrant.

2. The system of claim 1 , wherein the dehydrant is at least one selected from the group consisting of P 4 O 10 , calcium chloride, silica gel, and any combinations thereof.

3. The system of claim 1 , wherein the dehydrant is P 4 O 10 .
