Description

High-voltage electric field preserving machine for foods and fruits

The utility model belongs to natural food, and fruit anti-corrosive fresh-keeping processing technology field relates to that a kind of molecular structure that adopts high voltage electric field to handle to make food produces polarization and the device that reaches the purpose of anti-corrosive fresh-keeping.

In the prior art before the utility model,,, or protect with inert gas, special fluid nothing more than freezing, refrigeration, dehydration, dry or pickle with inorganic salts for generally fresh-keeping, the method for anticorrosion treatment of animal and plant food.For the industrialization food of producing in enormous quantities, also can adopt the ultraviolet ray irradiation, ultrasonic wave is handled, or with the method for chemical treatments.Adopt freezing method,, be undoubtedly method preferably animal foods such as fish, meat, eggs, but need be in long preservation under the freezing state, just can reach purpose anticorrosion, storage, for fresh-keeping, powerless, and the apparatus expensive that needs, the energy charge electricity is not suitable for storage in enormous quantities yet.Adopt cold preserving method, can be fresh-keeping, but freshness date is too short, generally surpasses an only week, and also keep away the growth of unavoidable mould during the refrigeration, anticorrosion problem can't resolve.Adopt dry, dehydration method, though can reach the purpose of long preservation, the food after drying, the dehydration does not just have FF to distinguish the flavor of again after the infusion, and the nutrition loss is many.As for pickling, obviously not good method with inorganic salts.And use chemical treatments, be that people avoid the method that adopts as far as possible.In recent years, adopt ultraviolet ray irradiation or ultrasonic wave to handle, one of on the contrary less expensive, simple method, but how on earth is effect? how to move towards family, also be difficult to certainly.

At present, a kind of employing high voltage electric field processing food is arranged and make food reach fresh-keeping, anticorrosion, and the method for energy long term storage.Though the mechanism of this method still imperfectly understands, but through a large amount of evidences, the food of under minimum electric current, high voltage, electric field, handling, not only can keep original delicious flavor, and can place at normal temperatures 4-5 month, some in addition can deposit 10 months and never degenerate, also some food is after high voltage electric field is handled, its weight also increases to some extent.This phenomenon gives people with enlightenment, has proposed the new method of a kind of simple, obvious results food fresh-keeping, anticorrosion storage.But to so far, the equipment of not seeing this method of employing as yet comes out.

The purpose of this utility model is, according to above-mentioned food fresh-keeping, anticorrosion, new method, the new approaches of storing, design that a kind of electric current is minimum, voltage is high, can produce that high voltage electric field ensures safety really, and has automatic demonstration, automatically the novel foodstuff preservation and antisepsis treating apparatus of warning function.

Now the utility model technical solution is described below:

The utility model shows that by casing (1), security protection switch (2), panel (3), time warning (4), work (5), tap changer (6), power switch (7), positive plate (8), power line (9), negative plate (10), high pressure generator (11) constitute (see figure 1).The output head anode of high pressure generator (11) connects positive plate (8), and negative pole connects negative plate (10); Time alarm (4), work display (5), tune switch (6), power switch (7), power line (9), all from high pressure generator (11) circuit, draw and be installed on the panel (3); Positive and negative pole plate (8), (10) are installed in the casing (1); Casing (1) madial wall is provided with some lattice laths (12), is to be provided with for the distance of adjusting between positive and negative electrode plate (8), (10); Security protection switch (2) is to be provided with for the misoperation that prevents power switch (7).

The high pressure generator of this device (11) schematic block circuit diagram as shown in Figure 3.220 volts of voltages are after transformation, and one the tunnel connects delay control circuit (19); One the tunnel connects oscillating circuit (14), forms dc high-voltage output end and connect positive/negative plate (8), (10) after frequency conversion (15), boost (16), high-voltage rectifying filtering (17); Delay control circuit (19), alarm circuit (18).The most preferred embodiment circuit diagram of the high pressure generator of this device (11) as shown in Figure 4.220 volts of power supplys are after 1B power supply transformation is boosted, through D ₁～D ₄Rectification one utmost point pipe rectification after, the one tunnel sends into delay control circuit, another road is sent into by R ₁, C ₂, W ₁, BG ₁, C ₃, C ₄The vibration, the frequency changer circuit that constitute, again through the 2B step-up transformer, high-voltage rectifying silicone tube D ₅High-voltage filtering capacitor C ₅, form high direct voltage output and be added on the positive and negative electrode switch XK ₂And resistance R ₂Setting be for behind powered-down, make that the electric charge that remains on the positive and negative pole plate discharges rapidly, off-load.

Now that description of drawings is as follows:

Fig. 1: this device front view

The A-A of Fig. 2: Fig. 1 is to profile

Fig. 3: this device high-voltage generator circuit theory diagram

Fig. 4: this device high pressure generator most preferred embodiment circuit diagram

Wherein:, (1) casing, (2) security protection switch, (3) panel, (4) time reports to the police, (5) work shows, (6) high-voltage switch gear, (7) power switch, (8) positive electrode plate, (9) power line, (10) negative electrode plate, (11) high pressure generator, (12) lattice lath, (13) power supply, (14) electronic, (15) frequency conversion, (16) boost, (17) high-voltage rectifying filter circuit, (18) alarm, (19) time-delay control, (20) high direct voltage output

When using this device, at first need the negative electrode plate (10) that processed food is put in the device is gone up (below), then by the lattice lath (12) on casing (1) sidewall, suitably adjust positive electrode plate (8) behind the food 15～30mm that places, shut chassis door, turn on the power switch, make high pressure generator produce the food of 10,000～1.5 ten thousand volts of high pressure placements after under this high voltage electric field processed 5～10 minutes, by relay indicating light and time-delay, the polarize beginning handled and finishing of alarm circuit notice people, powered-down then, open gate, guaranteeing under the situation that power supply is disconnected, take out processed food, the food of this processing is placed at normal temperatures and was all never degenerated in 4～5 months, thereby has reached anticorrosion, fresh-keeping purpose.

The utility model is compared with prior art, and anti-rot and fresh-keeping method is simple, and is effective, and required equipment structure is simple and easy, implements easily, not only can carry out the processing of food fruit in enormous quantities, can also enter huge numbers of families and substitute refrigerator, the refrigerator that involves great expense. Be applicable to that warehouse, shop, wholesale department and huge numbers of families that various kinds of foods is stored use.
