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

The preparation method of dried persimmon
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
Embodiment one:Raw material selection is first carried out, surface is chosen and is completely carried out again at cleaning without bad spot, without rotten persimmon  Reason.The persimmon of selection is cleaned using cleaning machine, removes the dust and spot on persimmon surface, then, carries out heated-air drying. Cleaned treated persimmon is put into baking oven, and the circulating air that temperature is 100 DEG C is sent into baking oven, dries 5.5 days, removes 50% moisture in persimmon, afterwards, is dried in vacuo.The fruit treated through heated-air drying is put into vacuum drying chamber, Heat under 8.5KPa vacuum, first heated 1.5 hours at a temperature of 510W power, 49 DEG C in two steps, complete the first step and add Heat.Heated 2 hours at a temperature of 390W power, 41 DEG C again, complete second step heating, finally, carried out underbalance pulse microwave and do It is dry, sprayed in three import for the vacuum pipe that temperature is 60 DEG C, pressure is 4KPa, centre and outlet dry sections every 1 minute Move once, co-dried 0.5 hour, obtain the dried persimmon that moisture content is 18%.
Embodiment two:Raw material selection is first carried out, chooses surface completely without bad spot, without rotten persimmon, then carry out at cleaning Reason.The persimmon of selection is cleaned using cleaning machine, removes the dust and spot on persimmon surface, then, carries out heated-air drying. Cleaned treated persimmon is put into baking oven, and the circulating air that temperature is 100 DEG C is sent into baking oven, dries 6 days, removes persimmon In son after 50% moisture, it is dried in vacuo.The fruit treated through heated-air drying is put into vacuum drying chamber, Heat under 8.7KPa vacuum, first heated 1.8 hours at a temperature of 500W power, 50 DEG C in two steps, complete the first step and add Heat.Heated 2.3 hours at a temperature of 400W power, 40 DEG C again, complete second step heating, finally carried out underbalance pulse microwave and do It is dry, sprayed in three import for the vacuum pipe that temperature is 50 DEG C, pressure is 6KPa, centre and outlet dry sections every 1 minute Move once, co-dried 0.7 hour, obtain the dried persimmon that moisture content is 19%.
Embodiment three:Raw material selection is first carried out, chooses surface completely without bad spot, without rotten persimmon, then carry out at cleaning Reason.The persimmon of selection is cleaned using cleaning machine, removes the dust and spot on persimmon surface, then, carries out heated-air drying. Cleaned treated persimmon is put into baking oven, and the circulating air that temperature is 100 DEG C is sent into baking oven, dries 6.5 days, removes In persimmon after 50% moisture, it is dried in vacuo.The fruit treated through heated-air drying is put into vacuum drying chamber, Heat under 9.0KPa vacuum, first heated 2 hours at a temperature of 490W power, 51 DEG C in two steps, complete first step heating. Heated 2.5 hours at a temperature of 410W power, 41 DEG C again, complete second step heating, finally carry out underbalance pulse microwave drying, Every 1 minute spouted one in three import for the vacuum pipe that temperature is 40 DEG C, pressure is 8KPa, centre and outlet dry sections It is secondary, co-dried 1 hour, obtain the dried persimmon that moisture content is 20%.
