COMBINED APPARATUS FOR CONTINUOUS PRODUCTION OF PULP-LIKE CONCENTRATES Russian patent published in 2008 - IPC A23P1/10 A23P1/12 A23L1/212 A23P1/06 

FIELD: canned and food concentrates engineering, in particular, continuous-action equipment for producing of pulp-like concentrates from fruit and vegetables.

SUBSTANCE: apparatus has charging hopper with transportation screw, casing incorporating two coaxial shafts and three chambers communicating with each other, of which chambers first and second chambers are made conical and third chamber is made cylindrical. In first chamber there is feeding coil mounted on high-speed shaft, and vertically mounted knives, with rotational angle of said knives enabling movement of product along chamber. Lower part of first chamber is made perforated and is connected to juice collector. In second chamber there is low-speed shaft with screw having two coils, first of said coils being made perforated and second coil being continuous. Two branch pipes are positioned in the vicinity of second chamber, said branch pipes being designed for introducing of steam and additional components such as sugar syrup, aromatizers, and structuring agents. Immovable grid with openings is provided at the end of second chamber. There is low-speed shaft in third chamber, said shaft having diameter increasing toward charging opening, and variable-pitch screw is mounted on said shaft. There is immovable grid with openings at the end of third chamber. Casing of third chamber is equipped at its outside with tubular insulated electric heaters. Cylindrical-conical vacuum chamber is attached to discharge unit of third chamber. Vertical shaft mounted within vacuum chamber has frame mixer fixed in conical part of said chamber, and screw. Steam chamber disposed on the outside of conical part of vacuum chamber is provided with steam feeding branch pipe and condensate discharge branch pipe. In lower part of vacuum chamber there is sluice-type vacuum gate, in cylindrical part of vacuum chamber there is branch pipe for removal of evaporated steam.

EFFECT: improved quality of ready pulp, reduced material and power consumption, and increased efficiency of apparatus.
