Description
Technical field
The present invention relates to the stir-frying of walnut kernel and go scarlet system, and in particular to a kind of tilt bed core based on Electromagnetic Heating
Scarlet device is removed in peach kernel lifting stir-frying.
Background technology
Walnut is healthy food, through being added to frequently as auxiliary material to increase nutritive value of food in food, is such as compared now
The deep processing of walnut kernel more prevailing is to make Manufacture of Walnut Milk and refinement walnut oil.Wherein, the fat content of walnut be up to 65%~
70%, shelter has first of woody oleiferous plants, there is the good reputation of " oil depot on tree ".In the international market, walnut oil is described as " east olive
Oil ", consumers are equally enjoyed with olive oil.However, walnut kernel surface has one layer of close brown skin clothing (to be commonly called as red
Clothing), containing more tannin and pigment, research shows, the tannin contained in walnut kernel is to produce bitter taste and cause beverage brown
The main reason for change.Tannin can not only influence the mouthfeel and color and luster of walnut oil, can also influence the stabilization of walnut protein and protein
Property, it is unfavorable for the intensive processing of walnut kernel.In order to preferably play the health of walnut and nutritive value, whether walnut product
Processing is still added to walnut as auxiliary material in other food, and the peeling research of walnut kernel has great significance.
With the high speed development of modern agriculture, people tend to variation for the demand of agricultural product, to this agricultural production of walnut
The producer that product carry out deep processing is also more and more.Up to the present, most of walnut deep processing producers all use boiling, chemical drugs
The methods of agent washing, removes the scarlet on walnut kernel surface, and these chemical reagent go the mode of detestaing to have the quality of walnut kernel
Considerable influence, it can hereafter be discussed in detail.Therefore it can be realized on the premise of walnut kernel quality is not influenceed and efficiently remove scarlet automatically
Machine can be well adapted for the demand in market.
At present, in the market is consulted related data and shown also without a kind of mechanism that can preferably remove walnut kernel scarlet,
In the case where ensureing that walnut kernel is not polluted by chemical reagent, Baking out goes the method for scarlet feasible.
Through retrieval, the dipping by lye method (patent No. of Zhao Xizhou inventions：CN204707949U) it is side by dipping by lye
Method removes walnut kernel scarlet.Dipping by lye method mainly soaks kernel, dissolving connection at a certain temperature by sig water
The pectic substance of kernel and kind skin, so that kernel separates with kind skin, the effect of peeling can be subsequently reached by cold water flush.Controlling
In the case of making concentration of lye and temperature, this method decortication effect is notable, equally also brings some problems.Alkali lye has certain
Corrosivity, soak remove the peel during, corrosion of the alkali lye to kernel causes the decline of kernel quality.Low-concentration alkali liquor soaks
Under bubble, to reach ideal decortication effect, kernel need to soak 1~3min in alkali lye, during this period of time, with the time
Increase, decortication effect is all the more obvious, but alkali lye dissolving kernel in protein and oil quantity it is also more and more, increase the matter of kernel
Amount loss, adds the damage to kernel.Soaked at low temperature according to the alkali lye of higher concentration, be then not easy to the complete of kernel
Peel, kernel can equally be corroded by, which being soaked under high temperature, causes quality variation.By contrast, the side soaked using low-concentration alkali liquor medium temperature
Method improves kernel peeling rate best results on the premise of kernel quality is ensured as far as possible.But using dipping by lye peeling side
After method, the part kind skin in artificial removal's kernel groove is still may require that during later stage peeling, therefore automaticity is not high.Together
Sample, chemical reagent used in soda solution grouting has reagent residual in the last more or less meeting of processing on kernel, causes food security
Problem.If the walnut kernel after peeling is used for food processing field, this barking method is worthless.
Through retrieval, blanching method is also a kind of now more common kernel barking method, and kernel is first put into boiling water by this method
Immersion, then stewing system form.But this method equally also encounters the problem of identical, during being soaked with boiling water and being boiled in a covered pot over a slow fire system, if
Want to improve kernel decortication efficiency, it is necessary to increase the time of immersion and stewing system.However, boiling water immersion can increase the water content of kernel,
Make kernel hair continuous, the increase for boiling in a covered pot over a slow fire the time processed is even more that can change the water content and quality of kernel.Drawn according to experimental result, ensureing core
While benevolence peeling rate, the time for reducing the optimal boiling water immersion damaged to kernel and stewing system is respectively 6min and 5min.But
Walnut-meat hulling effect after so handling is unsatisfactory, and peeling efficiency is low, also larger to kernel qualitative effects, in post-production
During be equally faced with kernel groove the situation of difficult peeling.It is follow-up to still need to manually remove kind skin at kernel groove, this
Production efficiency and automaticity are lessened, improves production cost.Equally, the walnut kernel quality obtained after so handling is more
To be soft, or even secondary injury can be caused to kernel in process, the working process of next step can be also resulted in greatly
Difficulty, while also limit the range of work of kernel reprocessing.
Through retrieval, prior art discloses a kind of heating drum apparatus for frying capsicum, it is mainly by separate type fan, tail
Screw-drive mechanism composition in portion's striker plate, charging aperture (discharging opening) and cylinder.When stir-frying starts, first from throat-fed,
Cylinder inside spin is just turning to feeding inside cylinder, and high pressure draught impacts isolate as caused by separate type fan during stir-frying
Material and impurity, less impurity are separated by barrel stomata and excluded, and larger impurity has screw-drive mechanism to drive to impurity exclusion
Mouthful, but the phenomenon for discharging material by impurity outlet simultaneously occurs.Meanwhile the stomata on barrel is easy to produce during discharge stir-frying
Raw gas vapor, but be provided with heat-insulation layer outside stomata but greatly limit the function of stomata.And the device goes out
Material mouth is also charging aperture simultaneously, and input and output material is realized by the rotating of cylinder internal thread, therefore feed inlet and outlet is not closed, but this
One device also significantly reduces the heat insulation effect of mechanism.More most important is exactly that the material of the device can produce accumulation now
As solid accumulation can cause secondary injury to the capsicum of stir-frying.Because walnut kernel quality is softer, be squeezed easily be deformed and
Breakage, if such device is directly used in the heating stir-frying of walnut kernel, can do great damage phenomenon to walnut kernel surely, therefore
What the device cannot be used for kernel directly heats stir-frying.
In summary, while peeling, alkali lye can dissolve grease and egg in kernel for above-mentioned soda solution grouting and blanching method
White matter, the walnut that dipping by lye is crossed endangers there may be Liquid Residue so as to be produced to human body, and hot water can improve the aqueous of kernel
Amount, high temperature can also destroy protein, all it is difficult to ensure that not destroying kernel quality, therefore kernel be injured also larger.Above-mentioned stir-frying
Uneven, stir-frying heat insulation effect is poor, stir-fry the cumbersome time-consuming, material of device input and output material and impurity there is also being heated to material for heater
Separating effect is bad and a series of problems, such as material can produce accumulation.For the walnut kernel of soft texture, if simply
Ground directly processes according to nut fruits heating stir-frying machine, undoubtedly can cause irremediable damage to the integrality of walnut kernel, directly
Female connector is unworkable with above-mentioned stir-frying heater.

The size of vortex is relevant with the electric conductivity of metal material, magnetic conductivity, physical dimension.These vortex consumption electric energy,
In induction heating apparatus, metal can be heated using vortex.The size of vortex and the electricalresistivityρ of metal, magnetic permeability μ, thickness
Spend h, metal and the coil relating to parameters such as distance δ, exciting current angular frequency.The calculation formula of vortex is as follows
In formula：J is the vortex that alternating flux is formed on calandria surface in the circle for think radius r；σ is calandria metal
Conductance；ΦmFor the magnetic flux in radius r circles.
Heated object and electromagnetic induction heating coil are combined together, 2~4mm gap is left in centre, when in magnetic field
The magnetic line of force is cut by wall of inner container, the magnetic line of force and produces countless small vortex, makes wall of inner container moment local pyrexia.The theory of vortex
It is δ to go deep into depth.
ρ is resistivity (10 in formula-8Ω·mm)；F is frequency (HT)；μ is permeability (4 π × 10-7T/A).Practical application
The depth that middle regulation I (x) is down at the 1/e of surface eddy intensity is " depth of current penetration ", is computed proving, 86.5 heat
It is to occur in the thin layer that depth is δ.
It is h to consider one piece of thickness, and resistivity ρ, radius is a circular metal plate, is placed in magnetic induction density B, with time alternation
Magnetic field in, in order to calculate thermal power, it is the π r of dr, Zhou Changwei 2 that circular metal plate is divided into several width along the sense of current,
Thickness is h metal foil cylinder, and the induced electromotive force of any one thin cylinder is
Bao Jian resistance is
So the instantaneous thermal power of thin cylinder is

By theory analysis with searching data, it is determined that a kind of prioritization scheme of the thickness of inner cylinder wall of inner container I -06.
If QHeat waste=QDissipate+QStore (8)
Then have
The thermal conductivity factor of λ in formula --- material, kJ/ (mh DEG C)
Δ t --- the temperature difference of inner cylinder wall of inner container and room temperature, DEG C
S --- the thickness of inner cylinder wall of inner container, m
The average area of dissipation of F --- inner cylinder wall of inner container, m2
ρ --- the unit weight of inner cylinder inner bag wall material, kg/m3
C --- the specific heat capacity of inner cylinder inner bag wall material, kJ/ (kg DEG C)
τ --- the heat time
When
Then
As shown in Fig. 4 (a), feed inlet and outlet uses the left-handed input and output material internal thread I -01 of embodiment 1, during charging, hydraulic stem III -
06 rises and makes that Electromagnetic Heating roller is inclined upwardly and roller rotates clockwise, and input and output material internal thread is similar to using left-handed
Helix transporting device, part walnut kernel can be transported in cylinder, another part can dump directly into, due to existing for gravity
Reason, efficiency during charging can be higher than discharging；In heating process, hydraulic stem III -06, which declines, makes roller keep level and rolling
Cylinder still holding rotates clockwise, and the effect that internal thread has backgauge again prevents walnut kernel from flying out；During discharging, roller tilts down
To internal thread side level and rotate counterclockwise, the discharging of internal thread reverse push kinetonucleus peach kernel.
Fig. 4 (c) be material particles discharging when at female thread portion velocity analysis figure, if the rotating speed of roller is n, by
Triangle ABC is obtained：
VCloseCos ρ=AB sin α (12)
V in formulaCloseFor the sum velocity of material particles, ρ be material to the angle of friction of helicoid, α is thread helix lift angle.
Because
So
According to resolution of velocity relation, the axial velocity of material particles can be obtained：
With coefficient of friction
U=tan ρ (16)
Above formula is substituted into obtain：
Due to
And
Therefore, by above-mentioned various substitution and by converting, the axial velocity calculation formula of material particles can be tried to achieve：
As can be seen from the above equation, under certain rotating speed, material can obtain preferable axial direction to pitch s within a certain range
Transporting velocity, the pitch of internal thread should not be too small, and pitch is too small to influence transfer efficiency；Pitch is excessive and can cause axial promotion
Power is insufficient and tangential force increase, transfer efficiency reduction is equally also resulted in, so pitch should be within the scope of one.
Alternatively embodiment, as shown in Fig. 4 (b), feed inlet and outlet does not have screw thread, simply smooth barrel, this
Kind of mode directly pours into material in cylinder, does not need screw thread to be promoted with the rotation of cylinder during due to input and output material, so can be carried during input and output material
High certain efficiency, but do not have female backgauge to act in heating process, it is necessary to tilt bigger angle just during discharging
With reference to the optimal selection of III -06- hydraulic stems, it can consider completely everywhere, preferably screwed embodiment is more suitable.
Fig. 5 (a) show the isometric drawing of curved tooth shape lifting blade I -02, and it is by core that curved tooth shape lifting blade I -02, which is mainly made,
Peach kernel is shed to being walnut kernel thermally equivalent in the air, prevents walnut kernel from contacting for a long time with barrel to be heated to pasting by walnut kernel surface
Shape.Have two fixed screw holes I -28 on curved tooth shape lifting blade I -02, it is symmetrical, bolt I -12 through fixed screw holes I -
28, the curved tooth shape lifting blade I -02 of right angle code I -15 is fixed together, then it is further in the side of bolt I -12 with nut I -14
Fixation prevents vibrations from causing bolt falling, and the other end of right angle code I -15 is fixedly connected on inner cylinder wall of inner container I -06 using bolt I -12
On, it is easy to the replacing of lifting blade using the method for the fixation curved tooth shape of right angle code I -15 lifting blade I -02；Curved tooth shape lifting blade I -02
The curved tooth shape for being 125 ° -150 ° in free one end, with the rotation of cylinder, material is taken up from cylinder low spot, indentation, there material
Start to shed at about 125 °, to when going to bigger angle, the material on arc section sheds end, and spreading region is more common
Lifting blade is big；Due to the presence of tooth type structures, the moment spreading on cylinder section of every piece of lifting blade is in two lines shape material, is changed
The moment spreading on cylinder section of single angle lifting blade is the state of a wire.Because the advantage of above-mentioned two reverse side is deposited
Decentralization of the walnut kernel on cylinder section can be effectively improved, to ensure walnut kernel evenly heated.To prevent walnut
Benevolence has secondary damage in heating, and the material of curved tooth shape lifting blade I -02 should select nontoxic relatively soft material (such as resistance to
The plastics of high temperature).
Shown in Fig. 5 (b), the angular range of lifting blade is at 125 ° -150 °, primarily to ensure lifting blade in lifting,
Material can be shed on striker plate as far as possible, material is shed in the air uniformly, can more uniformly be heated, prevent material heap
Product and extruding are impaired.It is 135 ° first to assume lifting blade angle, and when roller rotates, material is kicked up and shed by lifting blade, works as material
In minimum point, taken up by lifting blade, due to the effect of lifting blade, when material is taken up rotation to 120 ° or so, lifting blade is opened
Beginning sheds material, and is allowed on striker plate, until when rotation is about to 220 ° or so, spreading just terminates substantially.Work as lifting blade
When angle is less than 125 °, material can be larger with lifting blade movement angle, material is crossed striker plate, so as to shed less than striker plate
On.And when lifting blade angle is more than 150 °, material is smaller with lifting blade rotational angle so that when material is shed, it is impossible to and
When fall on striker plate.The angle of lifting blade is excessive or too small can all cause material fully can not kick up and shed uniformly, therefore
Lifting blade angle is arranged on 125 ° -150 ° by us.
As shown in Fig. 6 (a) and Fig. 6 (b), T-shaped striker plate I -0301 and M shape striker plate I -0302 are two kinds of striker plates

02 is applied in combination, and as shown in Fig. 6 (c), the striker plate that is applied on whole axle facilitates to be scattered from curved tooth shape lifting blade I -02
The walnut kernel to get off can be all fallen on striker plate, the time that striker plate increase walnut kernel stays aloft, so fully improving
Walnut kernel in the decentralization on cylinder section, the difference from Example 2 of embodiment 1 is that the free end of embodiment 1 changes
For T-shaped plate, M shape striker plate I -0302 is on falling after walnut kernel, and with the rotation of inner cylinder, walnut kernel can fall on cylinder quickly
Bottom, and have certain contact on T-shaped striker plate I -0301 between each T-shaped plate, walnut kernel has very big probability from one
Fallen in individual T-shaped plate in another T-shaped plate, thus further increase the decentralization in cylinder of walnut kernel, be heated more
Uniformly, and walnut kernel will not contact the long time on barrel, so accomplishing further to protect to walnut kernel.But T-shaped is kept off
The processing of flitch I -0301 relatively M shape striker plate I -0302 is difficult, but because walnut kernel needs in heating process
Very high protection and thermally equivalent, so prioritizing selection T-shaped striker plate I -0301.Striker plate considers when material selects and arc
Tooth form lifting blade I -02 is identical, and material is also identical with curved tooth shape lifting blade I -02.
Alternatively year embodiment, can also select Z-shaped striker plate, and its design principle is similar with T-shaped striker plate.

Drop to make roller tilt up or down, so relative rotation, institute can occur between hydraulic stem III -06 and connecting shaft III -07
Coordinated with the cooperation between it using less gap；The lower end of hydraulic stem III -06 directly interference fit is enclosed on pedestal III -08
Hydraulic pressure support bar III -05 on.Due to the gross weight of roller and material when this device needs to bear drum functions, thus stress compared with
Greatly, intensity and the higher material of hardness should be used, while relative motion can occur between part mostly, abrasion is brought, because material
Material should have certain wearability.
Such as Figure 10, shown in Figure 11, heating part uses Electromagnetic Heating, and Electromagnetic Heating is to be added by magnetic field to wall of inner container
Heat, so needing unique circuit and program to produce magnetic field, specific curent change is 50HT alternating currents → direct current → 20-
40KHT high-frequency alternating currents high-frequency alternating magnetic field → 20-40KHT induced-currents (vortex) → heat.The first step is preheating, due to electricity
Quickly, thermal conductivity is very high, and the temperature that we require heat to only has 100 DEG C or so, so preheating time for the speed of magnetic heating

The temperature signal of temperature sensor, a transmission high temperature signal, another transmits low-temperature signal, and after temperature reaches, high temperature passes
Sensor passes information to temperature controller, disconnects the circuit of Electromagnetic Heating, with the reduction of temperature, when temperature is low critical to one
During value, another temperature sensor transmits signal, makes temperature controller restoring circuit, makes roller continue to heat, the temperature of such roller
Remain within the scope of one.To differ, be obtained by consulting literatures because there is temperature field, the temperature of each position in roller
Know, it is minimum in the temperature of material mouth, close to centre position and close to the temperature highest of the position of wall of inner container, so in order to meet roller
The temperature of interior everywhere is all in the range of this, so the sensor of monitoring high temperature should be put into temperature highest place in roller,
And the sensor of low temperature is controlled then to be put into feed inlet and outlet, the minimum place of temperature.
As shown in figure 9, temperature controller includes PV display screens IV -01, SV display screens IV -02, indicator lamp IV -03, function
