Drying principles), whole process carries out in the environment of vacuum, this for vacuum drying.
Wherein vacuum frying is the completion of continuity under vacuum, and product oil content is low, and product is in negative pressure state, this
Food processing is carried out under conditions of relatively hypoxia, can mitigate in addition avoid oxidation (such as fat rancidity, enzymatic browning and
Other oxidation deteriorations etc.) brought by harm.In negative pressure state, using oil as heat transfer, the moisture (Free water of food product
With part in conjunction with water) it can sharply evaporate and spray, make to organize the formation of loose porous structure, be produced to obtain the fried of high-quality
Product；The meaning of centrifugation de-oiling is under the subnormal ambient of vacuum, and the degree that the oil immersion of surface of material enters gap structure is not deep, at this time
More oily (comparing with antivacuum) can be thrown away material using the centrifugal force of material basket rotation, realize and subtract oily technique；Finally
It is that ultimate drying is reduced to water content of food within the scope of 3% or so safe moisture using vacuum drying, completes product drying
Process.Since vacuum frying is only primary drying, the oil absorption of food can be controlled by control vacuum frying degree, and be discharged
In process of vacuum drying after edible oil, food is no longer contacted with edible oil, no longer oil suction, therefore fat content will not rise again
Height, to achieve the purpose that oil-control.Generally speaking, vacuum oil may be implemented in vacuum frying+vacuum drying combined drying method
The fried purpose for subtracting oil.
The operation principle of the present invention is that:
Before frying, it will be packed into material basket 31 to fried material, open cover 29, the material basket 29 equipped with material is put into frying
In tank body 30, after shutting cover 29, starting vacuum pump 28 will be evacuated in tank body 30, and the edible oil of heat is passed through by D interface
In tank body 30, start fried；In frying course, material basket 31 can centrifugation shaft 33 drive under slowly rotate, make material uniformly,
It is adequately fried, the steam that frying generates is condensed into condensed water by steam condenser 27, and condensed water is flowed out by nozzle 79；It is fried
After, the edible oil of heat is pumped out by the centrifugal pump 34 with filtering function from D interface, while centrifugation shaft 33 is turned up
Revolving speed throws away the oil for being attached to surface of material, realizes traditional vacuum de-oiling function；It is finished to edible oil and conduction oil heat exchange
Afterwards, the conduction oil of heat is passed through collet 32 from C interface, by the heat transfer of conduction oil into tank body 30, realizes vacuum drying function
Energy.After drying, cover 29 is opened, material is taken out.Conduction oil hot in collet 32 is passed through into C mouthfuls of centrifugal pump stream

Out, the low temperature edible oil after being cooled is flowed out from B2 mouthfuls, flows into edible oil tank 49 by pipeline 46.
If second of frying need to be carried out continuously, valve 75, valve 18 are closed, opens valve 82, valve 77, valve 67,
Motive force is provided by centrifugal pump 81, the conduction oil in collet 32 is pumped out by C mouthfuls, by pipeline 78, pipeline 19, pipeline 66, from
B4 mouthfuls enter No. two plate heat exchangers 11；Meanwhile valve 44, valve 8, valve 15 are closed, open valve 47, valve 43, valve
9, valve 14, by centrifugal pump 48 provide motive force, edible oil is pumped out to and is passed through pipeline 46, pipeline 50, pipeline 10, from A3 mouthfuls into
Enter No. two plate heat exchangers 11 and conduction oil exchanges heat；
After heat exchange, valve 62, valve 60 are closed, valve 61, valve 59, valve 45 is opened, makes edible oil from A4 mouthfuls
Outflow, the medium temperature food by pipeline 56 from B2 mouthfuls of inflow No.1 plate heat exchangers 1, after opening simultaneously 2 heat exchanging of steam heater
It is reheated with oil, after being heated into high-temperature edible oil, closes valve 8, valve 60, open valve 7, valve 39, valve 35, make
High-temperature edible oil is flowed out from B1 mouthfuls, fried to carry out second from the fried tank body 30 of D mouthfuls of inflows by pipeline 55, pipeline 36；
Valve 12, valve 17, valve 18, valve 75 are simultaneously closed off, valve 13, valve 64, valve 16, valve 76, valve 74 is opened, makes

It, can be real by valve regulated by adding connecting pipe and valve when heat-exchange system connects two sets or more set frying systems
Show continuity frying and the heat exchange of conduction oil and edible oil is also realized and is carried out continuously, thus more energy saving.
Vacuum frying temperature is set as 90 DEG C~120 DEG C, and when the 1st frying, edible oil and conduction oil are all cold oil, temperature
About 20 DEG C, heat exchange process are as follows:
1. room temperature edible oil, → steam (steam more than 3 kilograms of pressure) heating (No.1 plate heat exchanger 1) → reaches oil
The edible oil of fried temperature (90 DEG C~120 DEG C) → enter deep fryer frying；
2. at the end of frying, edible oil is discharged under vacuum state,
In high-temperature edible oil → No. bis- plate heat exchanger 11 with conduction oil heat exchange → medium temperature edible oil (about 50 DEG C~60 DEG C)
1 cold water cooling → room temperature edible oil of → No.1 plate heat exchanger returns to oil tank；
In room temperature conduction oil → No. bis- plate heat exchanger 11 with edible oil heat exchange → medium temperature conduction oil (about 50 DEG C~60 DEG C)
→ No. tri- 21 steam heating of plate heat exchanger → high temperature heat conductive oil (about 70 DEG C~90 DEG C)；
3. after vacuum drying, conduction oil is discharged,
If power cut-off at this time, the drying of next tank is no longer carried out, then conduction oil is cold by No. three plate heat exchangers 21
Oil tank is returned to after water is cooling；If necessary to carry out the processing of next tank, then it is then exhausted from after discharging and loading another tank material
Conduction oil exchanges heat into No. two plate heat exchangers 11 with edible oil, then returns to storage after No. three plate heat exchangers 21 are cooling again
Oil tank；And edible oil is then first heated through No.1 plate heat exchanger 1 after No. two plate heat exchangers 11 exchange heat again, subsequently into frying
Tank is fried.And so on, it can be achieved that the power-save operation of recuperation of heat.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
