Abstract

The invention relates to a forward osmosis concentration system. The system comprises a seawater pretreatment clarifying tank, a first circular draw-off pump, a multistage draw solution evaporation regulating tank, transparent glass, a second circular draw-off pump, a secondary filtration device, a draw solution storage tank, a draw solution injection pump, a concentrated liquor draw-off pump, a concentration tank, a concentrated liquor injection pump, a forward osmosis device, a draw solution draw-off pump, a third circular draw-off pump, a water collecting pipeline and a water collecting tank. Water in raw juice is driven by osmosis pressure in the system to enter a draw solution through a forward osmosis membrane, thus realizing the concentration of the raw juice; the diluted draw solution can be evaporated into a high-concentration draw solution through a seawater baysalt technology, and is delivered back to the forward osmosis technology again as a draw solution, thus the high-efficiency cyclic utilization of the draw solution is realized, the engineering construction cost and the running cost are greatly reduced, and considerable economic benefits are achieved.

Description

technical field

[0001] The invention relates to a fruit juice concentration method, which is a technology for concentrating tomato juice by forward osmosis, which uses high-concentration brine as a drawing liquid to extract water from tomato juice. This technology is also applicable to the concentration processing of other fruit juices and medicines. Background technique

[0002] Tomato is a fruity vegetable with rich nutrition and delicious color. It is rich in vitamins, cellulose, pectin and lycopene. Lycopene is a good anti-cancer and anti-mutation antioxidant. It can Effectively prevent and treat various diseases caused by aging and decreased immunity. Therefore, it is widely favored by countries all over the world, but its harvest period is short, the market is concentrated, it is difficult to store for a long time, and it is not convenient for transportation. Therefore, it needs to be concentrated and processed into products that are easy to store to adjust its supply ...

Examples

Embodiment 1

[0036] Such as figure 1 The shown forward osmosis concentration system consists of 1, a seawater pretreatment clarification tank 2, a first circulation extraction pump 3, a multi-stage draw liquid evaporation adjustment tank 4, a transparent glass 5, a second circulation extraction pump 6, a secondary filtration device 7, Draw solution storage tank 8, draw solution injection pump 9, concentrate solution pump 10, concentration tank 11, concentrate solution injection pump 12, forward osmosis device 13, draw solution pump, 14, third circulation pump, 15, water collection Pipeline 16, sump form.

[0037] The connection relationship of each component in the system is:

[0038] The first circulation pump 2 is connected between the seawater pretreatment pool 1 and the draw liquid evaporation adjustment pool 3, and the transparent glass 4 is installed on the upper part of the draw liquid evaporation adjustment pool 3, and the outlet of the evaporation liquid on the draw liquid evapor...

Embodiment 2

[0056] Such as figure 2 The difference between the present embodiment and the first embodiment of the forward osmosis concentrated tomato juice system shown is that the membrane module of the forward osmosis device 12 is composed of four modules connected in series, and its operation mode is exactly the same as that of the first embodiment. In this implementation case, four components are connected in series to obtain tomato juice with higher concentration, which saves energy and facilitates storage and transportation.
