Description

one

The invention relates to the field of preserving products, namely, devices for concentrating fruit juices by freezing moisture.

An apparatus for concentrating fruit juices is known, which includes a cylindrical evaporator with a vertical shaft mounted inside it with a scraper for cleaving the ice film that is frozen on the wall of the evaporator.

The purpose of the invention is to ensure the continuity of the process of concentrating the juices and compactness of the apparatus.

This is achieved by the fact that the apparatus has a screw rigidly mounted on a vertical shaft to separate the chipped ice crystals and remove them outside the apparatus.

The drawing shows schematically the proposed apparatus and its section along A-A.

The proposed apparatus for concentrating fruit juices has a cylindrical body 2 fixed on the bed 1, inside which the evaporator is stirred. The evaporator contains a coil 3, an inner 4 and an outer 5 cylindrical shape, the cavity between which is filled with brine. Between the outer wall 5 of the evaporator and the body 2 of the apparatus, there is a heat insulating layer 6. Inside the working cavity of the apparatus, a vertical shaft 7 is installed along its axis with a scraper 8 for cleaving the ice paws frozen on the working inner wall 4. At the upper end of the shaft 7, a screw 9 is rigidly mounted, intended to remove the chipped ice crystals from the apparatus. The apparatus also has a tray 10 for discharging the mass of ice into the centrifuge, a nozzle 11 for injecting the nozzle 12 for removing the final concentrated juice into the concentrate collection. The sprocket 13 of the chain transmission from the electric drive 14 is rigidly mounted on the lower end of the shaft 7. The place of the exit of the shaft 7 from the working cavity of the apparatus is provided with an epiploon 15 to ensure the tightness of the latter.

The proposed apparatus works in the following way. The evaporator establishes the boiling point of the liquid refrigerant, optimal for obtaining juice of the desired final concentration. Pre-chilled to a temperature close to the freezing point of water, fresh juice is fed to the chain changer to wash the ice and

then it is injected through ice pipe 11 onto ice crystals pushed out by the screw 9 from the working cavity of the apparatus and flows down. The actuator 14 leads into vrash, vertical movement of the shaft 7. Together with the shaft

7, a scraper 8, which cleaves a film of ice frozen on the working inner wall 4 of the evaporator and simultaneously serves as a mixer of concentrated juice in the working cavity of the apparatus. Thus, freezing of water from the juice to the required concentration is achieved, without freezing the entire product. Ready concentrated juice from the bottom of the working cavity of the apparatus through the pipe 12 enters a collection of concentrate. The ice shattered by the scraper 8 is removed by the screw 9 from the working chamber and along the stream 10 is fed to the centrifuge to separate the remaining juice concentrate from the ice. Freshly washed ice with ice is used for further technological needs. The process of freezing and removing part of the Yolagi in the form of ice from fruit juice goes on continuously. Claims An apparatus for concentrating fruit juices, comprising a cylindrical evaporator with a vertical shaft mounted inside it with a scraper for cleaving the ice film frozen on the evaporator wall, is different in that in order to ensure the continuity of the process of concentrating the juices and compactness of the apparatus it has an auger rigidly mounted on a vertical shaft for separating - chipped ice crystals and removing them from the apparatus.
