Abstract
The invention discloses respectful Cheng month Fei Fei cake heat pump processing method, this method is that the persimmon fresh fruit for having dug skin is placed in drying chamber, carries out being heated to 45 DEG C, heating time 30 hours to it by heat pump；It is then placed between refrigerated dehumidification, carries out refrigeration cool-down to it by heat pump to 20 DEG C, while opening low temperature dehumidification machine, continuous dehumidifying 18 hours, utilize the moisture in low temperature dehumidification machine removal circulated air；After being repeated twice above-mentioned steps, the persimmon fruit by moisture content up to 40%, which is placed again into drying chamber low temperature, is slowly dried, the 20 hours time of 35 DEG C of temperature setting；By the slow exhausting of axial flow blower by Frequency Converter Control, the steam in drying chamber is extracted out to get dried persimmon while not reducing temperature in drying chamber.Circulating air heating persimmon fruit is formed in drying chamber using the heat that energy-efficient heat pump generates, substantially reduce process time, the quality that dried persimmon is improved by low temperature dehumidification keeps the dried persimmon processed much more high-quality in color, mouthfeel than the dried persimmon directly dried using the prior art.
Description
Technical field
The present invention relates to Yue Fei processing technology, specifically a kind of Yue Fei Fei cake heat pump processing method.
Background technique
Dried persimmon is the traditional snack of Chinese Famous, and nutritive value is very high, contained vitamin and sugared part it is higher than general fruit by 1~
2 times or so.Traditional processing method is to repeat work by natural drying, artificial kneading, the mould proof multiple tracks of sulphuring after fresh fruit to be dug to skin
Sequence lasts more than 20 old name for the Arabian countries in the Middle Easts into dried persimmon.
Summary of the invention
The invention aims to provide a kind of Yue Fei Fei cake heat pump processing method, can be greatly shortened using this method to only
There are 5 days process times, the dried persimmon processed is much more high-quality than traditional diamond-making technique production in color, mouthfeel, simultaneously
Comply fully with the requirement of high standard quality safety.
Realizing the technical solution of the object of the invention is:
Yue Fei Fei cake heat pump processing method, includes the following steps:
(1) the persimmon fresh fruit for having dug skin is placed in heat pump drying room, is heated up by heat pump dryer to it, while opening heat
Wind circulating fan is heated to 45 DEG C and keeps constant temperature, and the Hot-blast Heating time 30 hours.
(2) dried persimmon after heating is removed between being put into refrigerated dehumidification from baking room, refrigeration dress is installed in refrigerated dehumidification
It sets, low temperature dehumidification machine, circulating fan, refrigeration cool-down is carried out to dried persimmon by refrigerating plant, wind circulation is forced, when temperature is down to 20
DEG C when maintain constant temperature, at this time open low temperature dehumidification machine, utilize low temperature dehumidification machine removal circulated air in moisture, the dehumidification work time
18 hours, stop artificial kneading after dehumidifying stands 2 hours.
(3) after being repeated 2 times step (1) and step (2), moisture content is placed again into heat pump drying up to 40% or so persimmon fruit
Room, which carries out low temperature, slowly dries, and 35 DEG C of temperature setting, one side bottom of drying chamber is equipped with air inlet hole, in the air inlet hole opposite oblique upper
The other side opens up an an equal amount of air outlet, and axial flow blower is arranged on air outlet, is turned by Frequency Converter Control axial flow blower
The slow exhausting of speed, extracts the steam in drying chamber out while not reducing temperature in drying chamber, drying time 20 hours, persimmon at this time
For cake moisture content 30% or so, the entire workflow of dried persimmon processing is completed in artificial kneading after standing 2 hours.
The beneficial effects of the present invention are:
Circulating air heating persimmon fruit is formed in drying chamber using the heat that energy-efficient heat pump generates, since heat pump has simultaneously
The advantage of cleaning, environmental protection, energy conservation, be previous boiler, electric heating it is incomparable, substantially reduce process time, 120 hours
It is interior to complete；Persimmon fruit after heating enter back into dehumidifying between refrigeration cool-down, through supercooling make persimmon fruit internal moisture quickly from it is inner to
Persimmon fruit surface is oozed out into outside, the moisture on persimmon fruit surface is taken away by circulated air, while passing through the low temperature dehumidification machine removal in drying chamber
Moisture in circulated air finally carries out low temperature again and slowly dries, and rationally adjusts the continuously slow exhausting of wind speed, is not reducing
The steam in drying chamber is discharged in drying chamber while temperature, makes the dried persimmon processed than the dried persimmon directly dried using the prior art
Want much high-quality in color, mouthfeel.Entire processing method eliminates the anti-mildew technique of sulphuring, meets consumer to food
The strict demand of safety.
Specific embodiment
Embodiment:
Yue Fei Fei cake heat pump processing method, includes the following steps:
(1) the persimmon fresh fruit for having dug skin is placed in baking room, it is heated by heat pump, temperature 45 C heating time 30
Hour.
(2) dried persimmon after heating is removed between being put into refrigerated dehumidification from baking room, refrigeration dress is installed in refrigerated dehumidification
It sets, low temperature dehumidification machine, wind circulating system, refrigeration cool-down, the maintenance when temperature is down to 25 DEG C is carried out to dried persimmon by refrigerating plant
Constant temperature, at this time open low temperature dehumidification machine, using low temperature dehumidification machine removal circulated air in moisture, the dehumidification work time 18 hours,
Stop artificial kneading after dehumidifying stands 2 hours.
(3) it is repeated 2 times step (1) and step (2), after hot-air seasoning twice and refrigerated dehumidification, by moisture content up to 40%
Persimmon fruit be placed again into drying chamber low temperature and slowly dry, avoid the dried persimmon cake skin processed from doing, but the phenomenon that cake meat still wraps slurry,
The 20 hours time of 35 DEG C of temperature setting, one side bottom of drying chamber offers one 40cm × 40cm air inlet hole, on the air inlet hole opposite
Oblique upper side opens up an an equal amount of air outlet, axial flow blower is arranged on air outlet, axial flow blower wind speed is by frequency converter
Control changes axial flow blower air draft speed according to persimmon fruit moisture content, is continuously delayed by rationally adjusting axial flow blower revolving speed
Slow exhausting extracts the steam in drying chamber to get golden yellow color, dried persimmon in good taste out while not reducing temperature in drying chamber.
Claims (2)
