Abstract
A concentrated fruit juice powder obtained by a convection current vacuum freeze drying process that includes: selecting and preparing fruits by predetermined quality guideline; extracting fruit juice by inserting the fruits into a screw press juicing apparatus having a precutter and a screw press whose body surface varies non-linearly, which is configured to achieve a maximum extraction efficiency; adding probiotics into the extracted fruit juice; freezing the fruit juice mixed with the probiotics in molds using an individual quick freezer (IQF) to obtain frozen fruit juice blocks; and vacuum freezing the frozen fruit juice blocks using a convection current vacuum freeze drying apparatus.
Claims20
A concentrated fruit juice powder obtained from a process comprising following steps:
- (a) selecting and preparing fruits by predetermined quality guidelines;
- (b) extracting fruit juice from said fruits by feeding selected fruits from step (a) into a screw press juicing apparatus having a precutter and a screw press whose body surface varies non-linearly from a front end to a rear end;
- (c) adding probiotics into said fruit juice;
- (d) freezing said fruit juice mixed with said probiotics in frozen fruit juice molds using an individual quick freezer (IQF) to obtain frozen fruit juice blocks;
- and
- (e) vacuum freezing said frozen fruit juice molds using a convection current vacuum freeze drying apparatus.
A system for preparing a fruit juice concentrated powder, comprising:
- a screw press juicing apparatus having a precutter and a screw press whose body surface varies non-linearly from a front end to a rear end of said screw press;
- a convection current vacuum freeze drying apparatus comprising:
- a dryer chamber unit comprising a plurality of trays for depositing fruit juice blocks to be freeze dried;
- a convection current condenser unit, mechanically connected to said dryer chamber unit, comprising a plurality of first elongate heat exchange tubes, each of said plurality of first elongate heat exchange tubes having fins arranged around an outer circumference of each of said plurality of first elongate heat exchange tubes, wherein said plurality of first elongate heat exchange tubes substantially fill an internal volume of said convection current condenser unit;
- a refrigerator unit mechanically connected to said convection current condenser unit, operable to provide a cold refrigerant gas to said plurality of first elongate heat exchange tubes;
- a cooling tower unit mechanically connected to said convection current condenser unit;
- a primary vacuum pump unit, mechanically connected to said convection current condenser unit and said cooling tower unit, operable to provide a vacuum pressure to said convection current condenser unit;
- and
- a heater unit mechanically connected to provide a heat energy to both said dryer chamber unit and said convection current condenser unit;
- a controller unit;
- and
- a database electrically coupled to communicate with said controller unit, wherein said controller unit is electrically coupled to control and receive sensed operational settings from said dryer chamber unit, said convection current condenser unit, said refrigerator unit, said cooling tower unit, said primary vacuum pump unit, and said heater unit, wherein said database is configured to store predetermined operational settings and wherein said controller unit is operable to compare said sensed operational settings and said predetermined operational settings.
