Abstract
The invention belongs to the field of agricultural product processing, and discloses a loss-reducing drying and storage method for fresh peanuts after production in a production place. The invention has the positive effects that: the method has the advantages that the fresh peanuts are dried in a sectional mode, vacuumized, inflated and sealed for storage, the drying time is short, the peanuts can generate heat and go moldy when being harvested in rainy days, the quality of the peanuts is guaranteed, and the method belongs to a green and safe physical technology; the processing technology is simple and easy to implement, and industrialization is easy to realize.
Description
Technical field
The invention belongs to field of agricultural products processing, are related to a kind of new technology that the raw reduction after producing of fresh flowers is dry.
Background technique
In harvesting peanut period, if encountering the rainy day, peanut cannot be dried timely, because the high peanut of moisture easily occur it is mould
Become, to cause farmer, business economic loss.If being segmented when the harvest time of peanut encounters rainy days using mechanical drying
Formula is dried, and is first dried in fresh peanut to certain moisture with drying machine, then peel off on decorticator, then in blast drier
In upper drying peanut benevolence to safe moisture, carry out vacuumizing filling CO 2 airtight package, room temperature on vacuum packaging machine
Storage.The quality of fresh peanut under any weather condition can be ensured using segmented drying, can avoid making because of climate reasons
Fresh peanut cannot be dried in time and fever, mouldy etc. occurs, influence the quality of peanut raw material, also bring to enterprise and farmer
Certain economic loss.Therefore, using the dry technology of segmented with the side for vacuumizing filling CO 2 storage technique and combining
Method can quickly and efficiently dry fresh peanut and prevent fresh peanut because of phenomena such as generating heat, is mouldy appearance, ensure the product of peanut
Matter extends its storage period, will have great importance to reduction farmer, business economic loss.
Summary of the invention
The main object of the present invention is to provide a kind of dry new technology of raw reduction after producing of fresh flowers, is original with fresh peanut
Material such as is removed inferior grain, drying, peels off, dries, packs, vacuumizes, inflates, packs at processes, the room temperature storage.
Technical solution of the present invention is as follows:
The raw reduction after producing drying of fresh flowers and storage practice, include the following steps:
(1) raw material selection: defect ware will be removed after fresh peanut harvest；
(2) in 40 DEG C of drying machine dry 5-6h, drying is to moisture content within the scope of 21%-26%；
(3) it peels off；10% range is less than to safe moisture is small in 41-45 DEG C of air dry oven upper drying peanut benevolence moisture
It is interior；
(4) prepare composite preservative: reactor is added in chitosan, calcium propionate, beta carotene, rosemary, sterile distilled water
In stir evenly to get composite preservative；It takes the every 1000g of composite preservative obtained to be uniformly mixed with 2500g peanut raw material, takes
Peanut raw material out dries, and adds 2 packet 5g black technique of activated ferrous powder with deoxidier agent, (the black technique of activated ferrous powder with weight of every packet deoxidier
For 5g, it is purchased from Dongguan City, Guangdong Province Ling Xian Biotechnology Co., Ltd)；
(5) it packs: after 9, long 20-30cm, wide 10-20cm PA/PE co-extrusion film package bag packaging dryings
Shelled peanut；
(6) it vacuumizes gas flush packaging: being vacuumized on type of respiration gas packed packaging machine, 50% carbon dioxide is prepared in gazogene
+ 49% nitrogen mixed gas of+1% carbon monoxide, is being filled in packaging bag, gas flow 0.1-0.3Nml/h, is evacuated 1s, fills
The gas time is 0.5-0.8s, airtight package；
(7) it stores: being stored under room temperature (18 DEG C~33 DEG C).
To reach superior technique effect, the composite preservative proportion be 0.25% chitosan, 1% calcium propionate,
0.02% beta carotene, 0.01% rosemary, surplus are sterile distilled water；
It is vacuumized on type of respiration gas packed packaging machine, vacuum degree 0.08-0.09MPa, temperature is 25 DEG C, and the pumpdown time is
5-7s。
Have the characteristics that following three using the present invention: (1) can quickly and efficiently be dried under unfavorable weather conditions fresh
Peanut is avoided that because that cannot obtain phenomena such as dry fresh peanut generates heat, is mouldy rainy days in time；(2) inventive technique belongs to pure
Physical technique, safety, green, the edible safety of energy effective guarantee raw material；(3) patented technology is easy to operate, is easy to industrialization
Implement.
The positive effect of the present invention is: (1) using the dry fresh peanut of segmented, drying time is short, can be effectively prevented from
Phenomena such as fresh peanut encounters rainy weather in harvest and peanut is caused to generate heat, is mouldy, belongs to the physical technique of green, safety；
(2) implementation of the technology of the present invention opens the new channel of the raw reduction after producing dry technology of fresh flowers, reduces due to climate reasons
It causes that peanut is rotten, the harm such as mouldy, while decreasing the economic loss of farmer；(3) carbon dioxide and nitrogen gas come
Source is wide, at low cost, and product processing technique is simple for process, it is easy to accomplish industrialization.
