Description

A kind of tubers powder electric field dispersal device
Technical field
The structure design of tubers powder electric field dispersal device is the utility model is related to, it is mainly used in tubers agricultural production Product processing technique field, belongs to the typical technology problem in mechanization of agriculture field, and the utility model specifically provides a kind of rhizome Class powder electric field dispersal device.
Background technology
In the prior art, the crushing of rhizome vegetable, it is the common methods in processing of farm products, with crushing side in recent years The particle diameter of the progress tubers powder of method progressively more refines.But with the refinement of particle, powder is being processed, handle, deposited In journey all can root be agglomerated into larger particles again, due to the effect of power between particle, the particle reunited again is often more difficult for these It is scattered, so as to have impact on powder quality.The origin cause of formation of powder reuniting phenomenon, mainly due to three kinds existing between powder granule The effect of power, i.e. Van der Waals force, electrostatic force, liquid bridge power.Because the upper of temperature and moisture content occurs in material in crushing process Rise, friction of the particle between contactant can promote the effect of electrostatic force and liquid bridge power between particle (referring to document 1:King looks for hall, The Agglomeration Mechanism and sign and elimination [J] China powder technology of Li Mei, Liu Zhaogang, Hu Yanhong superfine powders, 2008,03:46- 51+59.)。
Powder reuniting refers to that primary sub-micron-powder is being prepared, during separation, processing and storage, be connected with each other, Interact and be bonded into larger particle clusters phenomenon (referring to document 2 by multiple particles:Ji Shoufeng, Li Gui spring superfine powder Progress On Agglomeration Mechanism [J] Chinese Mining Industries, 2006,15 (8):54-56,90.).During power production, either without Machine mineral raw material or organic agronomic crop all can produce powder reuniting phenomenon with the change of temperature and moisture content.Powder reuniting Phenomenon be it is a kind of be difficult the phenomenon that avoids, during Crushing of Ultrafine, powder reuniting phenomenon it is serious constrain disintegrating process.
With the development of PM technique and agro-processing technology, increasing people take to grinding for correlation Study carefully work.(referring to document 3:Research [J] electronic products of Xin Hui, a rock nano-powders reunion solution method and dispersion technology Exploitation and innovation, 2012,05:38-40.) by analyzing FAQs of the ultrafine powder in preparation and use to powder reuniting The ameliorative way of phenomenon is inquired into.(referring to document 4:Zhang Wencheng, Wang Jianrong, Shi Ruixia nano-powder dispersion technologies are ground It is industrial to study carefully the commerce and trade of progress [J] modern times, 2009,02:284-286.) summarize the reason for ultrafine powder is reunited, dispersion technology and change The mechanism of action of kind powder reuniting, and the progress of nano-powder is discussed.(referring to document 5:Cao Ruijun, Lin Chen Light, Sun Lan, Zhao call on woods, and Liu is total, goes into business into reunion and its removing method [J] PM techniques of factory's superfines, and 2006, 06:It 460-466.) have studied agglomeration mechanism and removing method in PM technique.Due to powder reuniting phenomenon What is understood gos deep into, and the method for improving powder reuniting phenomenon is also more and more.High voltage electric field processing, because it has in processing procedure Have and do not heat up, pollute the characteristics of small, efficiency high, receive the attention of processing of farm products industry, also therefore, one efficiently, safety, Processing unit simple in construction becomes the expectation of people.
With the development of Physical Agriculture and processing of farm products technique, the research for high voltage electric field is gradually goed deep into.Powder point Dissipate, the extraction of active ingredient and high voltage electric field composite drying effect technique etc. in powder charge characteristic and activity processing, powder Aspect has more in-depth study.
Referring to document 6:Ren Jun, Lu Shouci, Shen Jian, the electrostatic anti-agglomeration of ultra-fine grains is waited to disperse [J] Science Bulletins, 2000,21:2289-2292. appoints person of outstanding talent etc. to disperse to be studied to the electrostatic anti-agglomeration of ultra-fine grain, and it is one to show electrostatic method The effective anti-agglomeration process for dispersing of kind, it has significant anti-agglomeration peptizaiton to ultramicro powder.Xu Zheng, Lu Shouci have studied Carrying capacity is scattered on ultrafine powder electrostatic and its dispersion effect influences, and the powered property and rule of particle are studied, point Particle rule charged in corona field has been analysed with dispersion effect (referring to document 7:The kind carrying capacities of Xu Zheng, Lu Shou are to superfine powder Body electrostatic dispersion and its dispersion effect influence [J] China powder technology, 2004,10:227-231.).Li Guichun, Ji Shoufeng couple Wilsonii powder carries out electrostatic dispersion research, the experimental study dispersion effect and major influence factors of wilsonii powder agglomerate, And electrostatic dispersion effect is detected and evaluated with equipment such as Particle Size Analyzer, ESEMs;Experiment results proved, electrostatic Process for dispersing is to scattered wilsonii powder significant effect (referring to document 8:Li Guichun, record and keep the electrostatic dispersion of peak wilsonii powders Study [J] China powder technology, 2007,13 (8):151-153.);Han Z are carried out to high-pressure pulse electric processing tapioca Experimental study, shows that high-pressure pulse electric can make its molecular structure and physicochemical property change, adds dissolubility;Cause This high-pressure electrostatic field energy promotes powder to disperse, change its physicochemical property and have wide application prospect.
T.R.Bajgai and F.Hashinaga was tested spinach using high electric field drying mode first in 2001 Research, it was demonstrated that high voltage electric field have in agricultural material drying process do not heat up, high efficiency, low-power consumption the advantages of.Liang Yunzhang High electric field drying mechanism is studied with reference to domestic and international achievement in research, moisture is mainly led by electric field in the electric field in material Graviational interaction, action intensity are directly proportional to air, the dielectric constant of material and electric-field intensity.In addition, fourth Chang River, beam fortune Zhang Yu Experimental study has been carried out within 2004 to high electric field drying of carrot (referring to document 9:Fourth Chang River, beam fortune chapter high electric field dryings Experimental study [J] EIs of carrot, 2004,20 (4):220-222.);Fourth Chang River, Lu Jingli are right in 2008 Drying property of the beef under high voltage electrostatic field is analyzed;Bai Ya townshiies, Hu Yucai is in 2008 etc. to high voltage electric field Inquired into hot blast combination drying dried shrimps (referring to document 10:Bai Ya townshiies, Hu Yucai high voltage electric fields are combined with vacuum refrigeration Dry sea cucumber method and its utility analysis [J] High-Voltage Technologies, 2014 (7):2191-2196.);Huang little Li is equal to 2010 Microwave combination drying test has been carried out to the carrot by high-pressure pulse electric pretreatment;Result of study shows that high voltage electric field is A kind of effective drying means, due to the direct transmission of no heat, the temperature of material does not change significantly, and can keep thing The active ingredient of material is not suffered a loss (referring to document 11:The pretreatment carrot slice microwave drying experiment of Huang little Li, Yang Wei impulse electric fields [J] EIs, 2010,26 (2):325-330.).The maximum feature of high electric field drying technology be dried object not Heating, effectively save the color, smell and taste and bioactive ingredients of dried material.
