Description

Multifunctional food sterilization and disinfection cabinet and method for sterilization and disinfection thereof

Technical field

The invention relates to a grain processing device, in particular to a multifunctional food sterilization and disinfection cabinet and a method for sterilization and disinfection thereof.

Background technique

At present, no place in the world is immune to pollution. According to statistics, more than 300 mycotoxins are known. Mycotoxins pose a great threat to the storage and storage of food. 25% of the world's cereals are contaminated to a lesser extent. And China is the hardest hit of mycotoxins. Mycotoxins are very stable and resistant to high temperatures, even if heated to 340 ° C. For mycotoxins, it is not only specific (different molecular structure, large difference in toxicity), but also synergistic (the simultaneous presence of various mycotoxins can accelerate the toxicity of mold), and even more efficient (ie very low) The toxicity can produce significant toxicity). Among the mycotoxins, the most serious one is Aspergillus flavus, which mainly damages the liver and kidneys of the human body and has strong carcinogenicity. Its toxicity is 10 times that of potassium cyanide and 68 times that of arsenic.

Food is not only contaminated by mycotoxins, but also highly susceptible to bacterial toxins in life. When I was in 1987, I knew that high blood pressure, diabetes, cancer, skin diseases, etc. were caused by germs in the food. The bacterial toxin itself exists in nature, if given a condition, It will breed immediately. For example, in summer, the moisture in the air reaches a certain level, and they will taint food. Now it is found that there are more than 300 kinds of bacteria in the grain, and there are dozens of bacteria that cause harm. Some of the pathogenic toxins do not harm the people themselves, but when they are combined, they become toxins that are very harmful to people. group. These toxins harm humans. The world is studying how to suppress the damage of these viruses in the human body.

For the food disinfection problem, the main current measures are mainly ozone sterilization. However, ozone sterilization takes a long time, sterilization is not complete, and ozone causes nausea and dizziness. Studies have shown that after 24 hours of ozone sterilization, the mortality rate of rats is 80%. Therefore, ozone sterilization has been widely used. In addition, it was reported that cobalt 60 treatment (gamma ray) was used, that is, food modified by low cobalt. However, cobalt 60 is radioactive, and the treatment of such radioactive gamma rays is obviously not suitable for use at home. Modified food is not only harmful to the human body (gamma rays can cause cell variability in humans, and sepsis). Modified rice is easy to become “golden rice”, wheat is often “sticky wheat”, and the surface color of corn is also darkened, which completely changes the texture and taste of food, and the experience is poor.

Therefore, we urgently need a device and method that does not add any chemicals and does not harm humans and animals to sterilize food.

detailed description

The detailed description of the embodiments of the invention is set forth in the claims

The multifunctional food sterilization and disinfection cabinet of the invention is composed of a quantum resonance instrument and a nano-UV lamp, and utilizes the principle of quantum vibration. Using the combination of flipping and illuminating sterilization, the short-wave nano-UV disinfection lamp combined with the quantum resonance transmission method is used to rotate the beans, rice, noodles, etc. along a very regular pattern (very rhythmically flipping the objects in the pot) ), to make the nano-light reach direct, play the role of surface disinfection.

As shown in FIG. 1 to FIG. 2, a multifunctional food sterilization and disinfection cabinet comprises: a cabinet body 1 and an upper cover 2, the cabinet body 1 has an accommodation space therein, and an upper portion is provided with an opening, and the upper cover 2 is disposed on the cabinet body. At the opening. The upper cover 2 and the cabinet 1 may be integrally movable connection (preferably using a pivotal connection), or may be a separate arrangement (either directly or integrally, or through the connection between the cabinet and the upper cover) The magnet is arranged to be connected by magnetic means, or the pivotal connection is combined with the magnetic connection. The invention is not limited thereto, and any connection method that can be conceived by those skilled in the art should be included in the scope of the invention.

Please refer to Figure 3, Figure 4, Figure 5, Figure 6, and Figure 7, as shown in the figure:

The cabinet 1 has an accommodating space in which an inner pot 3, a support base 4, a vibration device 5, and the like are disposed.

Specifically, the support base 4 is used to support the inner pot 3, is disposed below the inner pot 3, can be in direct contact with the bottom of the inner pot 3, or can be connected to the inner pot 3 by the screw 6. A vibration device 5 is connected to the bottom of the support base 4, and the vibration device 5 drives the vibration of the inner pot 3 through the support base 4. The center of the lower surface of the inner pot 3 is convex upward to form a convex portion. The raised portion ensures that the food in the pot can be turned over well when vibrating.

The support base 4 is welded with a screw 6 that cooperates with the inner pot 3. The screw 6 supporting the base 4 is connected to the inner pot 3 to realize the connection between the inner pot 3 and the support base 4. The fixing of the inner pot 3 and the support base 4 can generally be carried out in the following three preferred ways:

The first type of connection: a fixing hole 10 is defined in the center of the top end of the convex portion of the inner pot 3. The screw 6 passes through the fixing hole 10 of the inner pot 3, and is then screwed and fixed by the nut 11, thereby realizing the support base 4 and the inner pot. A fixed connection between 3.

The second connection mode is that the top end of the screw 6 and the bottom end of the boss portion of the inner pot 3 are provided with magnetic matching devices, and the fixed connection between the support base 4 and the inner pot 3 is realized by magnetic attraction. That is to say, the top end of the screw 6 can be automatically sucked to the bottom end of the boss portion of the inner pot 3, thereby achieving connection fixing.

The above two connection methods are suitable for small pots with small volumetric capacity. For medium and large pots, the following third connection methods are generally adopted.

The third connection mode: the screw 6 is disposed above the support base 4, the number is two or more, and is equidistantly disposed on the support base 4, the top end of the screw 6 and the outer edge of the bottom end of the inner pot 3 Close to each other. Considering that the tip of the screw 6 is sharper, the outer surface of the inner pot 3 is scratched when vibrating, which affects the appearance and use. Therefore, the top of the screw 6 can be further processed to make the contact portion with the inner pot 3 more rounded. It is also possible to provide a smooth nut at the tip end of the screw 6, so that when vibrating, the nut directly contacts the outer surface of the inner pot 3, thereby reducing the scratch on the outer surface of the inner pot 3.

The above three connection methods can be used in any type of sterilization pot, and can also be selected as needed. The principle is that the vibration device 5 transmits the vibration to the support base 4, and the support base 4 transmits the vibration to the inner pot 3 through the screw 6, so that the food to be sterilized and sterilized in the inner pot 3 is continuously tumbling, and the tumbling is like boiling water. (Because the inner pot 3 is designed with a raised portion, there is no uneven turning), so that the food in the inner pot 3 is continuously exposed, exposed to the nano lamp, and then the nanometer is used to surface the grain. The germ is killed.

However, the present invention is not limited thereto, and any connection method that can be conceived by those skilled in the art should be included in the scope of the present invention.

The cabinet 1 is further provided with an integrally connected circuit control board and a power supply device electrically connected thereto for controlling the switch of the vibration device 5, and the vibration device 5 can transmit vibration to the inner pot 3 through the support base 4, thereby realizing the inner pot The continuous inversion of the food to be sterilized in 3. The outer periphery of the inner pot 3 is also provided with a limit device 11 for the limit when the inner pot 3 vibrates. When the inner pot 3 is vibrated, the vibration amplitude is not excessively large, and the grain is tumbling to the inner pot 3.

Please refer to Figure 6 and Figure 7, as shown in the figure:

The upper cover 2 has an inner surface 7 facing the accommodating space recessed inwardly to form a recess 8 in which the nano-UV lamp 9 is mounted. The nano-UV lamp 9 has a wavelength in the range of 235-275 nm. The distance between the nano-UV lamp 9 and the surface of the grain to be sterilized is ≤ 20 cm. The upper cover 2 is provided with a circuit control board and a power line electrically connected thereto for controlling the switch of the nano-UV lamp 9 in the upper cover 2. The above-mentioned nano-UV lamp 9 can be set to different quantities according to requirements. For small sterilization and disinfection cabinets, generally 2-3, for large sterilization and disinfection cabinets, 5-6 are generally used, and the sterilization distance is controlled within 20 cm, otherwise the sterilization effect is better. difference.

The cabinet body 1 and the inner cover of the upper cover 2 of the above-mentioned sterilization and disinfection cabinet are provided with an integrated circuit control board and a power supply device electrically connected thereto for simultaneously controlling the switches of the vibration device 5 and the nano-UV lamp 9, thereby achieving a device. The purpose of the operation can be controlled by one pass. Similarly, the two can also be set separately. When separating, two sets of control circuit boards and power lines must be separately set up for separate control purposes.

1) Open the upper cover 2 of the multifunctional food sterilization and disinfection cabinet, and uniformly put the food to be sterilized and disinfected into the inner pot 3;

2) Covering the upper cover 2, turning on the power, the vibration device 5 drives the support base 4 and the inner pot 3 to start vibrating and turning, and the food in the inner pot 3 starts to be turned over;

3) Open the nano-disinfection lamp 9 and keep the seal. After 2-20 minutes, the sterilization is finished and the power is turned off.

4) Open the upper cover 2, take out the grain, and complete the sterilization of the grain.

2) Cover the upper cover 2, turn on the power, turn on the switch of the nano-disinfection lamp 9 and the vibration device 5, the grain in the inner pot 3 starts to be turned over, keep the seal, and after 2-20 minutes, the sterilization is finished, and the power is turned off;

3) Open the upper cover 2, take out the grain, and complete the sterilization of the grain.

The above two methods of sterilization and disinfection differ in that the power supply of the upper cover and the cabinet of the first method is controlled separately, and the power supply of the second method is unified control, and in addition, for the small sterilization and disinfection cabinet, The pan can generally be taken out directly to facilitate the placement of the food to be sterilized.

The food grain referred to in the present invention includes but is not limited to: noodles, rice, beans and the like. Especially suitable for use in home and small processing plants. The invention is not only for traditional rice, white flour, corn The rice noodles have good sterilization and disinfection effects, and have good anti-virus effects on beans.

Utilizing a nano-UV lamp, it has a sterilization effect at a wavelength of 235-275 nm (the lamp has a service life of about 3000 hours), no sterilization at less than 235 nm, and no sterilization at more than 275 nm, so the present invention uses ultraviolet light of 235-275 nm. .

The principle of quantum vibration is used to realize the turning of the food to be sterilized and disinfected in the inner pot, so that the surface of the grain is continuously directed and sterilized.

The sterilization and disinfection cabinet of the invention can be made into various sizes of large, medium and small as needed. Generally, the inner pot capacity of the small sterilization and disinfection cabinet is 2kg, the diameter is 20cm, the height is 18cm, the food needs to be 8-10s for one turn; the inner pot capacity of the medium-sized sterilization and disinfection cabinet is 25kg, the diameter is 50cm, the height is 40cm, and the food is required to turn over 1 circle. -40s; large-scale sterilization and disinfection cabinet has a inner pot capacity of 100kg, a diameter of 1.1m and a height of 50cm. Table 1 compares the size of each model of the present invention.

Table 1: Comparison of the inner pot size of the multi-function sterilization cabinet.

型号model	容量(kg)Capacity (kg)	直径(cm)Diameter (cm)	高度(cm)Height (cm)
小型Small	22	2020	1818
中型Medium	2525	5050	4040
大型Large	100100	110110	5050

However, the present invention is not limited thereto, and any person skilled in the art, in actual operation, can adjust the inner pot size as needed, and all fall within the protection scope of the present invention.

The multi-purpose sterilization and disinfection cabinet of the invention can be used for sterilizing and disinfecting various foods such as rice, corn and white flour. The sterilization and disinfection method is described above (taking a small sterilization and disinfection cabinet as an example), and the results are shown in Table 2.

Table 2: Sterilization results of different foodstuffs for small sterilization cabinets.

The results show that for small sterilization and disinfection cabinets, because the food in the inner pot is less, the anti-virus time is shorter. Within 5 minutes, the sterilization effect is ≥96% for all kinds of food.

At the same time, the above experiment was carried out on the medium-sized sterilization and disinfection cabinet. The results showed that the anti-virus time was slightly prolonged due to the increase of the inner pot of food, in 10 minutes, regardless of the variety of food. The disinfection effect of food and grain surface is also ≥96%.

The research results of large-scale sterilization and disinfection cabinets show that within 20 minutes, the anti-virus effect of sterilizing and disinfecting effects on various food surface layers can be achieved ≥96%.

In this experiment, it was also found that if the sterilization time exceeds 20 minutes, although the pathogenic toxin is completely inactivated, the sterilization rate can reach 100%, but some foods have begun to appear powdered. Therefore, in combination with the above situation, the optimal sterilization time of the multifunctional sterilization and disinfection cabinet of the invention is 2-20 min, and the sterilization rate of the grain surface layer can reach 96%.

In addition, the sterilization and disinfection cabinet of the present invention has a particularly good destruction and decomposition effect on toxins present in food, chemical pesticide residues in food, and transgenic toxins. Related tests are in progress.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and the present invention may be variously selected and modified without departing from the spirit and scope of the invention. The scope of protection is defined by the claims and their equivalents.
