Abstract

The invention discloses a kind of preparation method of freeze-drying apple flakes, relate to food processing technology field, this method is on the basis of originally traditional drying bu sublimation technique, eliminate this operation of quick-frozen, before material pushes dry storehouse 1 hour, open refrigeration system, after material advances storehouse, must vacuum be made to reach below 133.3Pa in 30 minutes, now material be frozen state.Open heating system, control the temperature of the apple flakes in dehydration between-10 DEG C to 40 DEG C, spin cycle obtains product at 14 hours, and the apple flakes moisture content of system is below 5%.The apple flakes made by this method not only overcomes drying bu sublimation technique high energy consumption, also overcomes the shortcoming that mouthfeel is not crisp, has nutrient loss few, yellow of light color, crispy in taste than the apple flakes of common oven dry simultaneously.

Description

A kind of preparation method of freeze-drying apple flakes
Technical field:
The present invention relates to food processing technology field, particularly relate to a kind of preparation method utilizing drying bu sublimation equipment making apple flakes.
Background technology:
Existing dry apple manufacturing technology has three kinds, i.e. AD(hot-air seasoning), VMD(micro-wave vacuum) and FD(vacuum freeze-drying).Adopt the dry apple of drying processing and being namely generally called the making of AD method, its technological process is: apple peel, stoning, section, hot-air seasoning.Its advantage is that energy consumption is minimum, and shortcoming is that apple nutrient loss is serious, apple flakes surface drying shrinkage, shape difference, yellowish; Adopt VMD(micro-wave vacuum) remove apple moisture, its shortcoming is that apple nutrient loss is serious, and the apple flakes color that the color of apple flakes makes than AD method keeps better, but shape of product drying shrinkage, sheet shape is bad; Vacuum freeze-drying method (FD) makes apple flakes, usually adopts following technique, and raw material is selected, wash fruit sterilization, stoning, cutting, sterilization, paving dish, quick-frozen, lyophilization and packaging.Its shortcoming is that energy consumption is high, and mouthfeel is soft and not crisp, and the apple finished color after freeze-drying is pale, distortion.
Present dry apple quality problem: all there is obvious shortcoming with the apple crisp slices of AD, VMD, existing FD fabrication techniques: the apple crisp slices apple nutrient loss that AD and VMD technology is produced is serious, apple flakes surface drying shrinkage, shape and cross-color; In FD technology, quick-frozen operation is also that FD in general sense produces necessary operation, but only for apple flakes, the apple flakes that existing FD technology is produced is then the apple flakes internal structure after making freeze-drying because of this operation of quick-frozen is completely cellular, and cause apple flakes soft and not crisp, there is no crisp sensation and make its mouthfeel not good.Simultaneously on energy consumption problem: the apple flakes that existing FD technology is produced all has this operation of quick-frozen, also be that FD technology produces the high main cause of apple flakes energy consumption to the quick-frozen of apple flakes, general is all requirement Ku Wen less than-30 DEG C, quick-frozen 4---6 hours, cause energy consumption in production process too high and make FD apple flakes production cost too high.
Summary of the invention:
The object of the invention is to overcome above-mentioned technical problem and the preparation method that a kind of freeze-drying apple flakes is provided.
For achieving the above object, the technical solution used in the present invention is:
A preparation method for freeze-drying apple flakes, is characterized in that concrete steps are:
1) apple pretreatment: choose disease-free, non-rot apple, through cleaning, sterilization, mechanical or manual peeling, stalk, core part;
2) cut into slices: apple flakes apple being cut into sheet, and meet the shape required by technique;
3) paving dish is added: be laid in uniformly by apple flakes after in material disc and forward on materials vehicle shelf;
4) freeze-drying: materials vehicle is pushed dry storehouse, starts condenser system in 1 hour before apple flakes pushes dry storehouse, makes it to run well, the temperature of material recycle refrigerant reaches less than-30 DEG C, open vavuum pump group, must vacuum be made to reach below 133.3Pa in 30 minutes, now material be frozen state, open heating system, heat according to design temperature, when curve reaches unanimity, drying completes, time controling is at 12-18 hour, and obtained apple flakes moisture content is below 5%.
Draining and water dumping operation was also comprised before paving coils added step.
In described slicing step, the shape of section is sheet or fan-shaped.
Increase after slicing step and protect look step.
The invention has the beneficial effects as follows:
1) present invention eliminates this operation of quick-frozen, apple flakes its internal moisture before entering dry storehouse freeze-drying does not become tiny ice crystal just to enter freeze-drying operation in apple flakes solidified inside, dry storehouse is in the process vacuumized, apple flakes surface moisture sharply evaporates to be taken away heat that apple flakes is with (material evaporation process need absorbs heat) and apple flakes temperature is slowly declined, apple flakes internal moisture is until be down to less than 0 DEG C and enter just to start to form crystallization, at this moment crystallization is not the fine crystalline that quick-frozen operation produces, along with moisture changes sublimation process into by evaporation process in dry vacuum container, its internal moisture crystallization is increasing, until dry vacuum container just starts slowly to diminish after starting heating, therefore, the apple flakes inside that this FD technology is produced can not produce tiny uniform alveolate texture, but irregular pass structure, this structure is when dry run completes laggard dry vacuum container vacuum breaker, because inside and outside differential pressure is larger, the crisp internal structure of apple is due to irregular, a lot of hole is understood unbalance stress and subsides (if add quick-frozen operation after being destroyed, its internal crystallization is very even, the hole stayed after water sublimed also can be very even, thus be not easy to subside), normal temperature is dropped to along with temperature after delivering from godown, change software strategy into software-hardware strategy after the crisp middle sugar cooling of apple and make apple flakes crispy in taste, also freeze-drying apple crisp slices truly is just become.
2) also just because of eliminating this operation of quick-frozen, the apple flakes cost that this way is produced reduces greatly, through the contrast of technical staff, and the tried data measuring and calculating of the freeze-drying apple crisp slices made by this way, capable of reducing energy consumption about 10%; Technical staff is through following the tracks of measuring and calculating, and corresponding freeze-drying cost calculates rear reduction by 13.7% in detail.
Detailed description of the invention:
