Description
Technical field
The utility model relates to vegetables freeze drying equipment field, specifically refers to a kind of fluidization band tunnel freezer for vegetable drying.
Background technology
Drying keeps one of unlikely putrid and deteriorated method of material.Dry method has many, as dried, boiling dry, dry, spraying dry and vacuum drying etc.But these drying means are all carry out at more than 0 DEG C or higher temperature.The product of dry gained, be generally that volume-diminished, quality are hardening, some material there occurs oxidation, and some volatile composition major parts can lose, the material of some thermal sensitivity, as protein, vitamin sex change can occur.Microbes loses biologos, and dried material not easily dissolves in water.Therefore dried product has very large difference compared with before drying in proterties.And freeze-drying is different from above drying means, the temperature of drying substantially below 0 DEG C of product is carried out, namely carry out under the state freezed at product, until the later stage, in order to reduce the remaining water content of dry products further, just allow product rise to the temperature of more than 0 DEG C, but be generally no more than 40 DEG C.
Freeze drying is exactly containing large quantity of moisture material, carries out cooling in advance and is frozen into solid, then under the condition of vacuum, make water vapour directly distil out.And in left ice shelf when freezing of material itself, therefore its dry rear constancy of volume, loose porous.
Freeze drying advantage is a lot, as: freeze drying is carried out at low temperatures, therefore for the material particularly suitable of many thermal sensitivity.Sex change can not be there is as protein, microorganism and so on or lose biologos.Therefore pharmaceutically applied widely; Time dry at low temperatures, some volatile ingredients loss in material is very little, is applicable to some chemical products, medicine and food drying; In freezing dry process, the effect of microbial growth and enzyme cannot be carried out, and therefore can keep original proterties; Owing to carrying out drying under the state freezed, therefore volume is almost constant, maintains original structure, concentration phenomena can not occur; Dried material is loose porous, in spongy, dissolve rapidly and completely, almost recover original proterties immediately after adding water; Because drying is carried out under vacuo, oxygen is few, and therefore some oxidizable materials obtain protection; The dry moisture getting rid of more than 95-99%, make dry after product to preserve for a long time and unlikely rotten.
Therefore, freeze drying is at present in food industry, and especially the freezing aspect of vegetables is widely used.
The existing freezing equipment for vegetable drying, need longer cooling time, and refrigerating effect is not good, often meaning bursting by freezing vegetables, and freezing equipment is very complicated, the rather voluminous of refrigeration system, needs larger factory building, operates also very not easily.
Utility model content
It is faster that the purpose of this utility model is to provide a kind of freezing rate for vegetable drying, and refrigerating effect is better, and cost reduces relatively, takes up room less, is easy to the fluidization band tunnel freezer controlled.
The utility model is achieved through the following technical solutions: a kind of fluidization band tunnel freezer for vegetable drying, comprise the sealing liquid nitrogen container including liquid nitrogen, described liquid nitrogen container is provided with two pipelines, the pipeline being placed in liquid nitrogen inside is connected with compression gas tank, the pipeline being placed in liquid nitrogen inside is communicated with atomizer, pipeline between described atomizer and sealing liquid nitrogen container is also provided with solenoid electric valve, described atomizer entrance is also connected with blower fan by air supply duct, described atomizer exit directly passes in fluidization band freeze tunnel, described solenoid electric valve and blower fan are all connected with master control platform by cable.
The technical program is, by the gas in compression gas tank, the liquid nitrogen in sealing liquid nitrogen container is compressed to atomizer, the wind of blower fan conveying is simultaneously to atomizer place, by the strength of wind, liquid nitrogen stream is atomized when atomizer enters fluidization band freeze tunnel, place in fluidization band freeze tunnel and need freezing vegetables, the liquid nitrogen of atomization contacts in fluidization band freeze tunnel with needing freezing vegetables, by vegetables quick freezing, the vegetables of freezing flow out fluidization band freeze tunnel, by verifying the refrigerating effect of vegetables, solenoid electric valve is regulated to control the uninterrupted of liquid nitrogen at master control platform, with the wind speed size that blower fan exports, thus ensure to enable vegetables use the liquid nitrogen of optimal amount to carry out spray refrigeration.Can not only ensure that vegetables have best refrigerating effect like this, also can reach energy-conservation object simultaneously.
For better realizing the utility model, further, the gas in described compression gas tank is nitrogen.Use nitrogen as compression liquid nitrogen effluent air, the purity of liquid nitrogen can be ensured, other impurity can not be mixed with, thus affect refrigerating effect.
For better realizing the utility model, further, described solenoid electric valve is liquid nitrogen magnetic valve.Because liquid nitrogen is very low temperature flow, general magnetic valve liquid nitrogen stream through time, can freeze, or the situation such as corrosion, in order to avoid this situation, solenoid electric valve prioritizing selection is specially for controlling the liquid nitrogen magnetic valve of liquid nitrogen.
For better realizing the utility model, further, described refrigerating plant is also provided with low temperature measurement device at fluidization band quick-frozen tunnel exit.At refrigerating plant, low temperature measurement device is also set at fluidization band quick-frozen tunnel exit, can see intuitively freezing after the temperature of vegetables whether reach freezing requirement, thus to regulate and control, strengthen or reduce the spray of liquid nitrogen.
For better realizing the utility model, further, described blower interior is provided with variable-frequency governor, and the control cable of variable-frequency governor is connected to master control platform.Be provided with variable-frequency governor in blower fan, master control platform, by controlling variable-frequency governor, regulates the wind speed that blower fan exports, thus controls atomizer to the fogging degree of liquid nitrogen, realizes the cryodesiccated regulation and control of vegetables.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model can provide wider, that temperature is lower cold wind and rate of temperature fall faster by using liquid nitrogen as the refrigerant of vegetable drying;
(2) device of the present utility model due to than the direct spray heat exchange of liquid nitrogen evenly, rate of temperature fall is more moderate, though food also not easily causes surface checking at a lower temperature;
(3) in the utility model because liquid nitrogen is fully evaporated utilization, consumption also declines to some extent, comparatively liquid nitrogen spraying quick-frozen, and its cost decreases;
(4) the utility model replaces refrigeration system realization cooling huge in traditional fluidized quick-freezing apparatus with the cold wind of liquid nitrogen spraying atomization generation newly, decrease system equipment, have compressed initial outlay, liquid nitrogen flash freezer plant area area is very little, and the utilization rate of plant area improves greatly;
(5) the utility model is simple due to structure, and its stability is strengthened, and control more freely, use is applied.
