Description
Technical field
The invention belongs to inspissated juice method fields, and in particular to a kind of method of full embrane method inspissated juice.
Background technique
With the quickening of agricultural industrialization process and continuing to optimize for agricultural cultivation structure, inspissated juice product is increasingly
By consumers, while also causing China's orchard worker's extensive concern, there is good development prospect.Currently, concentration of juices work
Skill substantially there are two types of；One kind is multiple-effect evaporation technique, and one kind is filtration-reverse osmosis integrated membrane process technique.Since inspissated juice is
Drink directly affects consumer health, needs sterilization unit using evaporation technology, meanwhile, to guarantee as far as possible in evaporation process low
Temperature prevents nutriment in inspissated juice to be lost, therefore generally uses high pressure low temperature sterilization method, to containers demand height.Evaporation
A large amount of thermal energy are needed, therefore, this kind of method energy consumption is generally higher.
Filtration-reverse osmosis integrated membrane process, on the one hand, can effectively be gone using the ultra filtration unit in filtration-reverse osmosis technique
Except substances such as suspended particulate, bacterium, viruses, while retaining nutritional ingredient.Reverse osmosis process can effective inspissated juice, however,
Reverse osmosis process needs higher operating pressure, consumes energy still higher.
Summary of the invention
The present invention solves the problems, such as existing inspissated juice method, and there are energy consumption high-tech；And provide full embrane method inspissated juice
Method.
Fresh Juice successively passes through coarse filtration unit in the method for the present invention and ultra filtration unit removes oil removal and bacterium, then passes through
The concentration of membrane distillation system is crossed, realizes low temperature inspissated juice purpose.
To solve the above problems, the method for full embrane method inspissated juice carries out in the steps below in the present invention:
Step 1: Fresh Juice coarse filtration is handled；
Step 2: then obtaining dialyzate and concentrate by ultrafiltration membrance filter, concentrate is collected；
Step 3: the dialyzate heating that step 2 obtains, temperature is constant, then membrane distillation；
Step 4: repetitive operation step 3 is until volume becomes the 4/5 ~ 9/10 of feed volume, and complete concentration.
It further limits, ultrafiltration membrane described in step 2 is polyvinylidene fluoride (PVDF) ultrafiltration membrane, polyacrylonitrile ultrafiltration film, polyether sulfone
Ultrafiltration membrane or ceramic super-filtering film, molecular weight cut off 100,000 ~ 200,000；The kit form of ultrafiltration membrane is hollow-fibre membrane
Component, rolled membrane module, tubular membrane component or plate film assembly.
It further limits, temperature is constant at 40-80 DEG C in step 3.
Further limit, membrane distillation is carried out using following forms in step 3: direct contact membrane distillation, absorbing film steam
It evaporates, vacuum membrane distillation or gap field orientation.
It further limits, membrane module form is taken in plate type membrane assembly, or use during membrane distillation in step 3
Hollow fiber formula membrane module, or using there is the Kynoar of surface super hydrophobic performance, in polyacrylonitrile polymeric membrane it is a kind of,
Or using the ceramic membrane with ultra-hydrophobicity.
In inventive film distillation process, material liquid is by the feed side of the membrane module of hydrophobic property, and moisture is with vapor shape
Formula penetrates film, surveys and condenses in infiltration, constantly recycles, to reach concentration purpose.
The method of the present invention makes 5 ~ 10 times of concentration of juices；The energy consumption in evaporation and crystal process is reduced, is easily operated automatically,
Occupied area is small, and low energy consumption, and handling are simple.
The method of the present invention is mild due to operating condition, it is not necessary that equipment plus crosses the more heat of point, can reduce evaporation
The heat that method is lost in the process.Solar energy confession can also be used in the exhaust-heat heating that upstream factory can be used in process of the present invention
Heat, operating condition is mild, is a kind of environmentally protective novel concentration technology.
The present invention is complete, and embrane method inspissated juice can effectively remove suspended matter and bacterium, greatly reduce fruit juice water content, energy
Enough the bacterium of removal 99.999%, the taste of juice of preparation are good.
Specific embodiment
Embodiment 1: the method for full embrane method inspissated juice carries out in the steps below:
Step 1: fresh squeezing grape juice is filtered processing using rough filtering device, suspended solid is filtered out；
Step 2: ultrafiltration membrane is hydrophilic polyethersulfone hollow fiber film assembly, and molecular weight cut off is then by ultrafiltration membrance filter
150,000, intake pressure 0.2MPa, water yield 10m3/ d obtains dialyzate and concentrate, discharges after concentrate processing；
Step 3: the dialyzate that step 2 obtains is heated to 50 DEG C, constant 50 DEG C of temperature, then membrane distillation；
Membrane distillation uses ultra-hydrophobic polyvinylidene fluoride membrane component, and the dialyzate of certain temperature passes through the feed side of membrane module, contact
Angle 160o, moisture penetrates film with vapor form, in infiltration survey generation condensation (cold fluid is water (0-3 DEG C)), water yield 10m3/
d；
(reach concentration purpose) Step 4: repetitive operation step 3 to volume become feed volume 7/8 until until, and complete
It extracts.
Step 3 vapor utilizes downstream vacuum pump, and after condensation, vapor becomes water, can recycle, and is concentrated
Fruit juice.The present embodiment method high degree of automation, low energy consumption, and degerming rate is up to 99.999%, by concentration of juices to fresh squeezing grape juice
It is octuple, yield can be adjusted by control membrane area, and low operation temperature not be related to high pressure.
