METHOD FOR VACUUM DRYING AND DEVICE FOR SUCH METHOD IMPLEMENTATION Russian patent published in 2015 - IPC F26B5/04 F26B9/06 

FIELD: food industry.

SUBSTANCE: vacuum drying method involves simultaneous reciprocal over-rolling of two inverted sleeves in a closed chamber; the sleeves form cavities communicating with vessels filled with the product being dried and with the ambient environment. The two sleeves are relocated in the chamber by way of reverse rotation of rolls interacting with surfaces of deflected areas of the sleeves. A fluid agent is pumped into cavities formed by the deflected areas of the sleeves; steam generated in the chamber between the over-rolling sleeves is forced out into the ambient environment. Additionally, a device for the product vacuum drying is described.

EFFECT: performance increase, dimensions decrease, electric energy consumption reduction and the design simplification.
