Description
Technical field
The utility model relates to the drying equipment of food processing, particularly a kind of particulate food material drying device.
Background technology
In food processing, use beans comparatively common as raw-food material, the such as common food such as mung bean, red bean raw material, in order to ensure the healthy and safe of food, needs to clean material before processing, dries for the particulate food material after cleaning.Extensively adopt big-and-middle-sized tower dryer tool equipment at present.In tower dryer tool, the granule materials such as moistening beans are poured in dry channel, hot blast is blasted in dry channel, usually the dry channel of inside is made inclination, be convenient to beans like this and drop out hothouse according to gravity oneself, in order to the moisture in moistening beans granule materials being down to safety value during storage, need to blast the higher hot blast of temperature, the temperature of general hot blast is between 120 DEG C-160 DEG C, 12-16% can be reached like this by disposable for water content, because baking temperature is generally higher than after 100 DEG C, easily cause the explosion of granule materials, broken, be inverted material color and luster not nature, the problem that quality declines.
Utility model content
The utility model is intended to provide a kind of particulate food material drying device, to solve the problem that the higher hot blast of present tower baker serviceability temperature easily causes raw-food material to destroy.
Particulate food material drying device in this programme, comprise hothouse, be horizontally placed on the fluid bed in the middle part of hothouse, described fluid bed one end arranges charging aperture, the other end is provided with discharging opening, the lower surface of described fluid bed is provided with vibrator, slanted screen plate is provided with in the middle part of described fluid bed, fluid bed is divided into first class section and the second fluidisation section by described slanted screen plate, the first air inlet is provided with below described first class section, the second air inlet is provided with below second fluidisation section, the top of described first class section is also provided with backflow swash plate, described backflow swash plate is in the charging aperture of slanted screen plate, the top of described backflow swash plate is lower than the top of slanted screen plate, return flow line is formed between backflow swash plate and slanted screen plate, the width of return flow line is 3 ~ 5cm, the top of described hothouse is provided with waste gas outlet.
The drying principles of this programme is: put into by particulate food material in hothouse, Vibration on Start-up device makes material can move to discharging opening from charging aperture gradually, first particulate food material is in the first class section on fluid bed, first class section is by the first air inlet heat supply, the hot blast of 80 DEG C is passed into the first air inlet, evaporated by the water of this hot blast by particulate food material surface, after the water evaporation on material surface, because adhesive force reduces, the second fluidisation section can be entered by slanted screen plate, the hot blast passing into 100 ~ 120 DEG C to the second air inlet carries out internal moisture drying, because the granule materials epidermis entering the second fluidisation section can not exist Free water, the raising of temperature can not cause the destruction of particulate food material.Particulate food material surface also being remained to water can be moved upward by slanted screen plate, is then back to first class section by the swash plate that confluxes and continues dry.
The advantage of this programme is: particulate food material is divided into Two stage dryer, first removes surperficial Free water, can prevent high-temperature material gelatinization, avoids the situation that particulate food material damages; 2, form material return flow line by the cooperation of slanted screen plate and backflow swash plate, make surface only have the undried particulate food material of water to be back to first class section and carry out continuation drying, ensure that the completeness of dry materials.
Further, the upper surface of described fluid bed, slanted screen plate is provided with unhurried current tooth; By unhurried current tooth, granule materials is produced unhurried current, make material can stop the more time in drier, realize fully dry.
Further, described charging aperture is provided with feed hopper, and described feed hopper is connected with charging aperture by corrugated flexible hose, and the below of feed hopper is provided with filtration sieve plate.First carry out prefiltration to particulate food material surface water by filtering sieve plate, owing to being provided with vibrator in hothouse, when drying, vibration can produce coupling part and destroy, and can be cushioned by bellows to vibration, prevents coupling part from occurring damaging.
Further, described first air inlet is connected with the first heat exchanger, and the second air inlet is connected with the second heat exchanger, and the first heat exchanger and the second heat exchanger are connected on air blast by collecting pipe.When carrying out drying, 80 DEG C are set to the temperature upper limit of the first heat exchanger, ensure that the stream temperature of first class section is relatively low, only the moisture on material surface is evaporated, raw-food material can not be too high by the gelatinization of material epidermis because of steam temperature, is set to 120 DEG C to the temperature upper limit of the second heat exchanger; Because material surface moisture now is evaporated, add the temperature of air flow, material epidermis can not be affected.
Finally, the charging aperture of described hothouse is provided with scavenging conduit, and described scavenging conduit, collecting pipe are connected by reversal valve with air blast.After drying completes, the air after being will speed up by reversal valve enters to be switched in scavenging conduit, is cleared up by the material remained in hothouse by scavenging conduit, ensures the drying work of material next time.
