An apparatus for high speed continuous thermoforming of pulp materials into pulp based products including a beverage dispensing capsule comprising a body having a side wall and a base formed entirely of moulded pulp fibres, said apparatus comprising a holding tank for water and pulp fibres in suspension, a continuous feed belt of articulated mesh toolsets contoured to the preform shape of said products, said belt being inclined to allow partial immersion and partial withdrawal from said suspension by continuous rotation of said belt, vacuum means applied to said mesh toolsets to draw said pulp fibres onto said mesh toolsets immersed in said suspension to form a preform pulp mat of said product.

Methods and apparatus for vacuum forming and subsequently applying topical coatings fiber-based food containers. The slurry includes an embedded moisture barrier and/or vapor barrier, and the topical coating comprises an oil barrier comprising acrylate, rice bran wax, pectin, and pea protein.

An automatic forming machine for a pulp molding product and a manufacturing method therefor. During manufacturing, a slurry suction mold immersed in a slurry box suctions a slurry to form a slurry layer, and then ascends to leave the slurry box to assemble with an upper hot pressing mold, which moves in from an external space, for extrusion to form a preform; then the slurry suction mold descends into the slurry box for a second round of slurry suction; the upper hot pressing mold suctions the preform and returns in a reverse direction to an original position; then a lower hot pressing mold ascends for assembling to hot press and shape the preform to form a pulp molding product, and the lower hot pressing mold suctions the pulp molding product and descends to the original position; and a material receiving mechanism then suctions the pulp molding product and leaves the lower hot pressing mold for separate collection. The automatic forming machine for a pulp molding product can perform, after slurry suction, rapid cold extrusion for dehydration and rapid hot-press forming, thereby increasing a manufacturing speed, shortening a production cycle, and reducing manufacturing cost.
