PILOT PLANT

Supervisors:  dr inż. Hanna Kowalska, dr inż. Agata Marzec, lic. Mariusz Wojnowski

Panoramic view

Technological offer:

  • development of fruit and vegetable drying technologies in order to maintain and improve their quality and usefulness as consumer products (convective, microwave- convective, and radiator drying methods).
  • development of technologies of drying liquid raw materials to achieve their dry powder form.
  • drying of solutions or emulsions, e.g. juice on carbohydrate carrier.
  • microcapsulation method by spray-drying, e.g. enzymes, dyes, aromatic substances, lipid substances.
  • powder agglomeration, drying /granulation/ moistening/coating loose substances on fluid bed; application for loose materials in a form of: fine powder, granules, pellets, tablets or crystalline substances.
  • mixing of powder raw materials. Preparation of powder and granulate mixtures, also with liquid additives e.g. spreading of liquids (dyes, aromatics, and flavours) on a solid carrier in loose form; preparation of spice mixtures, nutrients and concentrates following any recipe.
  • cryo-concentration of fruit juices in a temperature below 0oC.
  • freezing – checking of the surface and intra material freezing processes.
  • saturation coupled with osmotic dehydration – application to produce low-processed foodstuffs, preserving features of fresh fruit and vegetables enriched with additional nutrient substances to supplement diet poor in these components.
  • membrane processes – carrying out ultra- and nano-filtration with the use of variable surface ceramic membranes.
