Description
Technical Field
The invention relates to the field of sterilization and detoxification of foods, in particular to a food processing device with a ceramic container.
Background
The high-voltage pulse electric field technology is one of non-heat treatment sterilization technologies, and the high-voltage pulse electric field is utilized to sterilize and detoxify food. The sterilization principle is as follows: the pulse electric field generates magnetic field, which alternately acts to increase the permeability of bacterial cell membrane, intensify vibration and weaken membrane strength, so that the membrane is destroyed, the material in the membrane is easy to flow out, the material outside the membrane is easy to permeate, the protection effect of the cell membrane is weakened or even eliminated, and at the same time, anions and cations generated by ionization of the material near the electrode act with the material inside the membrane, thus blocking the normal biochemical reaction and metabolism process in the membrane, etc. to kill the bacteria. The detoxification principle is as follows: for substances harmful to human bodies such as hormone, antibiotics, residual pesticides, heavy metal compounds and the like, the pulsed electric field can destroy the stability of chemical bonds, thereby destroying the molecular structure and achieving the purifying effect.
Due to the low material cost and insulation requirements, existing food processing devices often provide a plastic separator between the food and the electrode to provide insulation. Two common structures are disclosed in applicant's original patent CN 201510689507.7: in one common configuration, the food processing device is a container for holding food, plastic, and the electrodes are arranged on the outer wall of the plastic container; in another common configuration, a plastic housing is provided outside the electrode, which is disposed within the container in direct contact with the liquid. Although the plastic separation layer can play a certain insulating role, the plastic has poor stability, is easy to break down in a high-voltage pulse electric field, causes short circuit, causes the electric field to lose sterilization and detoxification effects, and has great potential safety hazard. And because the electrodes of the existing food processing device are all equal electrodes (namely, the two electrodes of which the sizes and the shapes are the same in a positive pair and a negative pair), the pulse electric fields generated between the two electrodes can cancel each other, so that the pushing and sucking actions of the electric fields are weakened, and the adsorption effect of the electrodes is not ideal.
Accordingly, there is a need for improvement and development in the art.

As shown in fig. 1 and 6, the present invention provides a food processing apparatus having a ceramic container, including a processing unit 200 for processing food. The processing part 200 includes a container 210 for containing food, at least one pair of electrodes, one of which is connected to the positive electrode of the high voltage pulse generating device and the other of which is connected to the negative electrode of the high voltage pulse generating device, and a pulsed electric field is generated between each pair of electrodes such that the pulsed electric field between each pair of electrodes passes through the interior of the container 210, and the pulsed electric field between each pair of electrodes passes through the wall of the container 210 at least once, and the food in the container 210 is sterilized and detoxified by the pulsed electric field. The interior of the container 210 refers to an internal space surrounded by walls of the container 210.
In the invention, the food mainly comprises solid food and liquid food, wherein the solid food comprises aquatic products, meats, vegetables, fruits, grains and the like, and the liquid food is conductive liquid and comprises water, milk, beverage and the like. In the case of treating solid food, it is necessary to add a conductive liquid, such as water or an aqueous solution, to the container 210, and the water or the aqueous solution is preferably used for immersing the food to be treated.
Because of the low material cost and insulation requirements, existing food processing devices often have a plastic separation layer between the food and the electrode to achieve the insulation effect, and in a common structure, a container for loading the food of the food processing device adopts plastic, and the electrode is arranged on the outer wall of the plastic container; in another common configuration, a plastic housing is provided outside the electrode, which is disposed within the container in direct contact with the liquid. Although the plastic separation layer can play a certain insulating role, the plastic has poor stability, is easily broken down in a high-voltage pulse electric field, and causes short circuit. In the present invention, ceramics include pottery, porcelain and purple clay.
Further, in order to ensure a high electric field transmittance while avoiding breakdown of the container 210, the container 210 is preferably made of ceramics, and the container is loose in texture and has a large number of pores, so that the container can be used as a good insulating material, and can ensure a high electric field transmittance, thereby avoiding the problem of sacrificing the electric field transmittance due to the improvement of the insulating effect and deteriorating the treatment effect. As a most preferred embodiment, the container 210 is made of purple clay, and the purple clay has a dual pore structure, so that the penetration rate of the electric field can be further improved, the electric field loss can be reduced, when a plastic container is adopted, a high voltage of about 6 ten thousand volts is often required to ensure a better electric field penetration effect, and when the purple clay container 210 is adopted, the same electric field penetration effect can be achieved only by about 3 ten thousand volts.
Because the electrodes of the existing food processing device are all equal electrodes (namely, the two electrodes of which the sizes and the shapes are the same), the pulse electric fields generated between the two electrodes can cancel each other, so that the pushing and sucking actions of the electric fields are weakened, and the adsorption effect of the electrodes is not ideal. In order to solve the problems, in the invention, one electrode of the paired electrodes has a larger area than the other electrode, and because the two electrodes are one by one and the intensity of an electric field generated near the small electrode is larger than that of an electric field generated near the large electrode, the pushing and sucking actions of the electric field are more obvious, the pushing force of particles is larger, and the adsorption effect of the electrodes is good.
Further, in order to ensure that the electric field can penetrate the container 210, the thickness of the wall of the container 210 is less than 2.5cm, and if the thickness of the ceramic container 210 is greater than 2.5cm, the penetration rate of the electric field is too low, and the sterilization and detoxification effects are lost. Preferably, the wall of the container 210 has a thickness of 3 to 5mm, and within this thickness range, materials can be saved, breakdown can be prevented, and a high electric field transmittance can be ensured.
In the present invention, the electrodes may be provided in various manners, and the electrodes may be in the form of a sheet, a plate, a bar, or the like, and in the form of a sheet, the electrodes may be planar or curved; the electrodes of the pair may or may not be opposed so long as the electrodes of the pair are capable of forming a pulsed electric field within the interior of the container and the pulsed electric field passes through the walls of the container 210 at least once.
When the pulsed electric field between the paired electrodes passes through the wall of the primary container 210, as one embodiment, one of the paired electrodes is disposed outside the wall of the container 210, and the other electrode is disposed above the container 210, and the pulsed electric field between the two electrodes passes through the bottom wall 212 of the primary container 210. As another embodiment, both electrodes of the pair are disposed at the sidewall 211 of the container 210, that is, one electrode of the pair is disposed at the outer surface of the sidewall 211 of the container 210 and the other electrode is disposed at the inner wall of the other side of the container 210 opposite to the one electrode, and the pulsed electric field between the two electrodes passes through the sidewall 211 of the primary container 210. As a third embodiment, one of the paired electrodes is provided on the outer/inner surface of the side wall 211 of the container 210, and the other electrode is provided on the inner/outer surface of the bottom wall 212 of the container 210.
To make the insulation between the pairs of electrodes better, the breakdown phenomenon is further avoided, and the pulsed electric field between each pair of electrodes passes through the wall of the container 210 twice. As one embodiment, both electrodes of a pair are provided at the sidewall 211 of the container 210, and both electrodes are provided opposite to each other, specifically, one electrode of the pair is provided at the outer surface of the sidewall 211 of the container 210, and the other electrode is provided at the outer surface of the sidewall 211 at the other side of the container 210 opposite to the one electrode.
As a preferred arrangement, as shown in fig. 6, one electrode 240 of the paired electrodes is disposed on the side wall 211 of the container 210 in a closed ring shape, and the other electrode is disposed on the bottom wall 212 of the container 210, specifically, the electrode 240 of the side wall 211 is disposed on the outer surface of the side wall 211 of the container 210, and the electrode of the bottom wall 212 is disposed on the outer surface of the bottom wall 212 of the container 210, wherein the electrode of the bottom wall 212 is disposed in the middle of the bottom wall 212 of the container 210. Since the electrodes of the bottom wall 212 are disposed in the middle of the bottom wall 212 of the container 210 and are located on the axial symmetry line of the closed loop electrodes (i.e., the positions of the two electrodes are symmetrically disposed in a balanced manner), the pulsed electric field generated between the electrodes of the bottom wall 212 and the closed loop electrodes is symmetrically disposed in a balanced manner, so that the electric field in the container 210 is uniformly distributed. The electrodes may be disposed on the outer wall of the container 210, the inner wall of the container housing 220, or the inner wall of the cover 100 (when the electrodes are disposed above the container 210).
The electrodes may be provided in one pair or in a plurality of pairs depending on the size of the container 210. When the electrodes are arranged in two pairs, one of the pairs of electrodes may be disposed on the sidewall of the container 210, i.e., both electrodes of one pair may be disposed on the sidewall of the container 210, and both electrodes may be disposed opposite each other, one of the other pair may be disposed on the outer surface of the bottom wall 212 of the container 210, and the other electrode may be disposed above the container 210.
In the present invention, the shape of the container 210 is not particularly limited, and the container 210 includes a side wall 211 and a bottom wall 212, and the shape of the container 210 may be a cylinder, an oval cylinder, a rectangular parallelepiped, or the like, and the bottom wall 212 of the container 210 may be a plane or a curved surface.
