Abstract
The preparation method of dried persimmon of the present invention belongs to food processing field, a kind of preparation method of dried persimmon is provided, processing is dried to dried persimmon in this way, is greatly improved drying efficiency, avoid wasting, improving the loss of planting household, improve the enthusiasm for production of dried persimmon planting household.
Description
Technical field
The preparation method of dried persimmon of the present invention belongs to food processing field, is related to a kind of drying means of dried persimmon.
Background technology
It is well known that containing large quantity of moisture in dried persimmon, the former fruit holding time is limited, and the holding time one, which is grown, easily rots, and makes
Its nutritional ingredient is obtained to be destroyed.Should mainly support components unchanged for keep dried persimmon, conventional method be using drying or squeeze the juice come
Dried persimmon is handled.Drying means therein is presently mainly to use family's small workshop mode drying means, this small work of family
Mill formula drying means is that dried persimmon is spontaneously dried by the heat of sunshine.Although can be right by the heat of sunshine
Dried persimmon carries out natural drying processing, but is had a great influence due to the thermal Finite of sunshine, and by weather condition change, therefore,
Is needed to the drying process with a collection of dried persimmon, the drying process time is longer, the drying process efficiency to dried persimmon 60 ~ 80 day time
It is low.Again because the time of family's small workshop mode drying means needs is longer, prolonged rainy weather is run into, dried persimmon is easily rotten
It is rotten, not only result in substantial amounts of waste, reduce the loss of planting household, can also dampen the enthusiasm for production of dried persimmon planting household significantly.
The content of the invention
The problem to be solved in the present invention is to provide a kind of preparation method of dried persimmon.Dried persimmon done in this way
Dry processing, is greatly improved drying efficiency, avoids wasting, improving the loss of planting household, and the production for improving dried persimmon planting household is positive
Property.
The invention solves above mentioned problem realized by following technical scheme：
The preparation method feature of dried persimmon of the present invention is to comprise the following steps successively, chooses raw material, chooses surface completely without bad spot, nothing
Rotten persimmon, cleaning treatment, the persimmon of selection is cleaned, remove the dust and spot of fruit surface, heated-air drying will
Cleaned treated persimmon is put into baking oven, and circulating air is sent into baking oven, dries 5.5 ~ 6.5 days, remove in persimmon 50% with
On moisture, vacuum drying, will through heated-air drying treat persimmon input vacuum drying chamber in, in 8.5 ~ 9.0KPa vacuum
Heat under degree, first heated 1 ~ 2 hour at a temperature of 490 ~ 510W power, 49 ~ 51 DEG C in two steps, complete first step heating, then
Heated 2 ~ 2.5 hours at a temperature of 390 ~ 410W power, 39 ~ 41 DEG C, complete second step and heat, underbalance pulse microwave drying,
Every 1 minute in the import for the vacuum pipe that temperature is 40 ~ 60 DEG C, pressure is 4 ~ 8KPa, centre and the dry section of outlet three
It is spouted once, co-dried 0.5 ~ 1 hour, obtain dried persimmon of the moisture content less than 20%.
As can be seen from the above scheme, because the present invention uses heated-air drying, vacuum drying and underbalance pulse microwave drying
Combined drying method, through on probation, processing is dried to same batch dried persimmon with the integrated processes of the present invention, it is only necessary to 6 ~ 8
Its time.Compared with background technology needs 60 ~ 80 day time, it is short to shorten more than the 10 times drying process times of process time, from
And substantially increase the drying efficiency to dried persimmon.Because drying time is short, drying efficiency is high, even if running into prolonged rainy days
Gas, dried persimmon are not easy to rot, and the waste that not only avoid, the income for improving planting household, can also greatly improve persimmon planting household
Enthusiasm for production., can be according to difference again due to the method for the present invention also intelligent controller can be configured in addition in step
The trophic structure of dried persimmon and different quality requirements realize one-touch intelligentized control method, so as to furthermore achieved that persimmon drying process
Large-scale and industrialized production.
Embodiment
