PLATE VACUUM-EVAPORATOR APPARATUS Russian patent published in 2011 - IPC A23B7/00 A23L1/212 

FIELD: food industry.

SUBSTANCE: invention is intended for application in canning industry in the process of production of pureed concentrates of fruit and vegetables. The plate vacuum-evaporator apparatus contains a vacuum chamber, vertical heat-exchange plates positioned parallel inside it, a feeding and a discharging devices, separators for capture of minute drops of the product from vapours being released. The plates have a wave-shaped profile, the plates are designed to be hollow with horizontal bafflers positioned inside them for ensuring zigzag movement of the heat carrier and are equipped with nozzles for supply and withdrawal of hot and exhaust heat carrier accordingly. A device for delivery of the original product is positioned above them mounted so that to enable relocation within the vertical plane assisted with pneumatic cylinders. A vertical chain conveyor is mounted between each pair of heat-exchange plates. On the conveyor chain links axes with flexible horizontal scrapers are incrementally located; the scrapers are arranged so that to enable touching the heat-exchange plates surface.

EFFECT: invention ensures fruit-and-vegetable puree quality enhancement, the evaporation process intensification, energy costs reduction, performance enhancement.
