Description of drawings
Fig. 1 is the logic diagram of batch type vacuum frying device of the present invention.
The specific embodiment
As shown in Figure 1, batch type vacuum frying device comprises oily heating container 1, vacuum frying chamber 3 and vavuum pump 8.Oil heating container 1 is used to receive new edible oil, and edible oil is heated, and is in the embodiment shown in fig. 1 to adopt 12 pairs of edible oils of electric heater to heat, but is not limited thereto, and for example can also utilize the mode of chuck heating to heat.Vacuum frying chamber 3 and oily heating container 1 join by pipeline, and be arranged on the top of oily heating container 1, after opening the loam cake 32 of vacuum frying chamber 3, can put into living raw material, be food materials (animals and plants food materials such as fruit, vegetables, seed, meat), vavuum pump 8 is used for vacuum frying chamber 3 extracting vacuum.
As the embodiment of the best, in the pipeline of vacuum frying chamber 3, also be provided with gas-liquid separator 8, condenser 6 and condenser receiving tank 7 at vavuum pump 8.Below describe and utilize device shown in Figure 1 to carry out the process or the method for the fried system of food materials:
(1) carries out the pre-treatment such as cleaning, cutting of raw material.
(2) add an amount of edible oil in the oily heating container 1 below device, adding an amount of edible oil can add automatically by constant displacement pump, adopt the heating of electrical heating or jacket steam, make to be heated to proper temperature, proper temperature is by the material of food materials and needs the degree of fried system to decide.
(3) the vacuum frying chamber on device top is 3 li, adds food materials in right amount in ready raw material basket 4.
(4) vacuum frying chamber 3 usefulness vavuum pumps 8 vacuumize operation, simultaneously logical cooling water in the condenser 6.
(5) vacuums in the vacuum frying chamber 3 suitably rise confirm after, the lower valve 2 of vacuum frying chamber 3 is opened, the edible oil that has been heated to proper temperature in the oil heating container 1 of bottom is drawn in the vacuum frying chamber 3 under vacuum state, heating container 1 disposes thermometer T1 and pressure gauge P1, can learn the proper temperature of edible oil or temperature required by thermometer T1 and pressure gauge P1, heating container 1 also disposes the chuck that can lead to steam, in chuck, behind the logical steam, can assist control oil temperature.
(6) in the vacuum frying chamber 3, under vacuum condition, the oil temperature is carried out suitable adjusting, make food materials in the fried while, the moisture that food materials comprised evaporates in a vacuum, and vacuum frying chamber 3 also disposes pressure gauge P2 and thermometer T2, know the oil temperature and guarantee safe pressure by pressure gauge P2 and the detected pressure of thermometer T2, temperature, same, also disposing the chuck that can lead to steam, the oily temperature of vacuum frying chamber 3 can be regulated by electric heater 31.
(7) finishing of Fried Fishes can be by the come-up of Fried Fishes, the affirmations such as rising of oil temperature.
(8) close vavuum pump 8, vacuum frying chamber 3 inner open vacuum are got back to atmospheric pressure state.
(9) open the bottom pump 2 of vacuum frying indoor 3, edible oil all flows back into following oily heating tank 1.
(10) in the vacuum frying chamber 3, after Fried Fishes placement certain hour drains oil, by the 3 interior taking-ups of the Fried Fishes after fried, cooling from the vacuum frying chamber.
(11) edible oil after refluxing in the bottom oil heating tank 1, because be fried operation under vacuum state, its acidifying, deterioration can be very low, after recycling for several times, (for example: the filtration of atlapulgite), can reuse carry out refinement treatment.
Fresh TRUFFLE (having another name called truffle, ferfas) as senior food materials, the maintenance of freshness is difficulty very, adopt preceding method and vacuum frying device in following condition, after carrying out the situation of fried processing, can obtain fried of the very good TRUFFLE of quality and contain unique TRUFFLE fragrance and the few TRUFFLE oil of acidifying:
Fresh TRUFFLE pre-treatment cuts into thick 3～5mm sheet after the washing;
Edible oil adopts sunflower oil to be heated to 150 ℃ in heating tank;
The vacuum 60Tovv that vacuum frying is indoor;
120 ℃ (following 180 ℃ of fried situation under the atmospheric pressure state) of fried oil temperature
About 3 minutes of fried time.
Therefore preceding method is particularly suitable for as a kind of ferfas sheet fried system method, perhaps ferfas sesame oil preparation method.
