Abstract
The invention discloses a method of pretreatment for chestnut storage. The method comprises the following steps: chestnuts are added in a pressure tank body through a feeding hole, enter the pressure tank body through isolation pressure of a two-stage feeding valve, is in vibration transportation in the pressure tank body and finally are discharged outsides the pressure tank body through the isolation pressure of a two-stage discharge valve; microwave radiation is carried out on the chestnuts in the vibration transportation process; in the pressure tank body, on one hand, compressed air is continuously bubbled into the pressure tank body to make the pressure in the pressure tank body constant at 0.2-0.8MPa, and on the other hand, air is extracted from the pressure tank body by utilizing a circulating fan, extracted damp and hot air is cooled, dried, dehydrated and then input into the pressure tank body, and thus the pressure air circulates. According to the method, chestnut continuous microwave back pressing pretreatment can be efficiently realized, the microwave energy is completely absorbed by materials, heat effect is realized, humidity control, enzyme deactivation, disinfection, sterilization and disinsection are promoted, particles are prevented from blasting, and the storage quality of the chestnuts is dramatically improved.
Description
Technical field
The method carrying out pretreatment before the present invention relates to a kind of Semen Castaneae storage.
Background technology
Fresh chest nut contains abundant moisture, trace element, sugar and starch, it it is nutritious special appetizing delicacy, but Semen Castaneae is generally difficult to storage, easily fermenting in storage, go mouldy or moth, existing cryopreservation technology can not be avoided Semen Castaneae to ferment in storage completely, go mouldy and moth.
Microwave energy by material selective absorbing, have the advantages that penetrance is good, material inside and outside entirety can realize rapid microwave heating effect, promotes that moisture is the most quickly removed, and Semen Castaneae can be made to inactivate, also can kill parasite simultaneously realize sterilization, effectively extend the shelf life.But the adventitia that Semen Castaneae sarcocarp covers coating of wax matter due to outer layer also has rigid shell, thus can affect the spilling of moisture when carrying out pretreatment, reduce drying efficiency, if heating can produce granule blasting phenomena by force, affect product quality.
Therefore, if use microwave back-pressure to be dried regulation moisture and sterilization, it is possible to give full play to the microwave permeability occasioned good rapid advantage of heat sterilization, simultaneously because compressed air back-pressure effect, the volume flow making spilling considerable moisture is substantially reduced, it is to avoid occur quick-fried grain phenomenon in preprocessing process.
Summary of the invention
For solving the problem that Semen Castaneae storage prior art exists, the present inventor, through lot of experiments, the method finally inventing the storage pretreatment of a kind of Semen Castaneae, uses the method can be effectively improved the storage quality of Semen Castaneae.
For overcoming the deficiencies in the prior art, the present invention takes techniques below scheme:
Adding Semen Castaneae in past pressurized vessel, Semen Castaneae is added by charging aperture, is entered in pressurized vessel by two-stage inlet valve isolation air pressure, and Semen Castaneae carries out vibrating transportation in pressurized vessel, isolates outside air pressure discharge pressure tank body finally by two-stage outlet valve；Semen Castaneae carries out microwave radiation during vibrating transportation；On the one hand compressed air is constantly blasted in pressurized vessel, make the pressure in pressurized vessel constant at 0.2-0.8MPa, on the other hand circulating fan is utilized to bleed from pressurized vessel, the hot and humid gas of extraction is lowered the temperature, input pressure tank body again after drying and dehydrating, realizing pressed gas circulation, cold compression air carries out contacting cooling down with the Semen Castaneae of vibrating transportation, it is achieved be dried once again.
The core of the present invention be full-closed system realize continuously microwave back-pressure be dried, sterilizing and cooling.Material turnover pressurized vessel is all to use series connection two-stage inlet valve to carry out pressure isolation, all multiple microwave generators can be arranged with reasonably optimizing on the top of pressurized vessel and the left and right sides, owing to metal wall can be totally reflected microwave, microwave energy will be realized heat effect by material absorption completely and promote to be dried, and microwave energy no loss also will not leak；Owing to there being compressed air back-pressure effect, the water volume flow overflowed during microwave drying is substantially reduced, thus effectively prevent expanded and quick-fried grain phenomenon.
Vibrating transportation can automatically spread under effect of vibration stir due to simple in construction, reliable, material, is particularly conducive to uniform pickup microwave assisted and is dried and sterilizing, and the pattern that conservative control vibrates can significantly improve efficiency, simultaneously extension device service life.
On the one hand compressed air forms back-pressure and prevents Semen Castaneae lobe expanded, and on the other hand compressed air unit volume gas enthalpy is greatly increased, and has good material cooling effect.When moisture content of material differs, required compressed air pressure also differs, and the technique effect obtained is the most different.
Utilizing said method to process Semen Castaneae, the storage time under Semen Castaneae room temperature can extend 80-200%.
Compared with prior art, beneficial effects of the present invention also resides in and can efficiently realize continuous microwave back-pressure Semen Castaneae pretreatment, and microwave energy is absorbed by material completely, realize heat effect, promote moisture regulation and enzyme denaturing, sterilize, sterilize, parasite killing, prevent granule explosion, significantly improve the storage quality of Semen Castaneae.
Detailed description of the invention
Hereinafter the method from Semen Castaneae storage pretreatment is described in detail.
