Description

Technical Field

[0001] This invention relates to a method and equipment for irradiation sterilization of ready-to-eat foods, belonging to the technical field of irradiation sterilization equipment. Background Technology

[0002] Ready-to-eat foods refer to a class of foods that do not require processing and can be eaten directly after opening the packaging (or in bulk). Ready-to-eat foods include fast food, canned food, puffed food, roasted food, baked goods, ready-to-eat seaweed, preserved fruit, dried fruit, health products, etc. Bulk ready-to-eat foods mainly include bulk preserved fruit and bulk frozen rice and flour products.

[0003] Irradiation sterilization is an effective method that uses electromagnetic waves generated by ionizing radiation to kill microorganisms on most materials. Radiations used for sterilization include electron beams, X-rays, and gamma rays. They can all control microbial growth or kill microorganisms in specific ways. X-rays and gamma rays can oxidize other substances or generate free radicals (OH·H) that then act on biomolecules, or act directly on biomolecules, breaking hydrogen bonds, oxidizing double bonds, destroying ring structures, or causing certain molecules to polymerize, thereby disrupting and altering the structure of biological macromolecules, thus inhibiting or killing microorganisms.

[0004] Before packaging, ready-to-eat foods need to be sterilized during processing. However, existing irradiation sterilization methods involve directly irradiating the raw materials in the storage tank. Although irradiation sterilization can still kill bacteria due to the large volume and diameter of the storage tank, it takes a long time. In addition, the food in the storage tank needs to be unloaded onto the filling equipment for packaging, which may cause the ready-to-eat foods to be contaminated again. Furthermore, the operation is complicated and inefficient. To address these issues, this invention proposes an irradiation sterilization method and equipment for processing ready-to-eat foods. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a method and equipment for irradiation sterilization of ready-to-eat foods to solve the existing problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an irradiation sterilization device for ready-to-eat food, comprising an irradiation sterilization chamber, a quantitative mechanism disposed at the top of the irradiation sterilization chamber, an irradiation component disposed at the upper end of the cavity of the irradiation sterilization chamber, a sterilization plate box assembly disposed below the irradiation component, and a pushing mechanism movably disposed in the left cavity of the sterilization plate box assembly. A filling box assembly is continuously disposed on the bottom right side of the sterilization plate box assembly. The lower end of the quantitative mechanism movably passes through the middle of the irradiation component and extends downward to the upper part of the left cavity of the sterilization plate box assembly. The front end of the filling box assembly extends to the outside of the front side of the irradiation sterilization chamber. The other end of the irradiation component extends to the side of the rear side of the irradiation sterilization chamber. The lower end of the pushing mechanism softly abuts against the bottom surface of the left cavity of the irradiation sterilization chamber.

[0007] A further improvement is that a cleaning chamber door is hinged to the upper front side of the irradiation sterilization chamber, and an external opening for the filling chamber assembly is provided on the right front side of the irradiation sterilization chamber. The cleaning chamber door has a double-opening structure.

[0008] A further improvement is that the metering mechanism includes a metering tank, a metering tank cover disposed on the top surface of the metering tank, a feed pipe connected to the lower end of the metering tank, a valve disposed on the feed pipe body, a telescopic pipe connected to the lower end of the feed pipe, a discharge nozzle connected to the other end of the telescopic pipe, a telescopic device vertically disposed on one side of the discharge nozzle, and a sensor disposed at the upper end of the metering tank cavity.

[0009] A further improvement is that the irradiation assembly includes two crossbeams, several fixed seats disposed on the left side of the two crossbeams, a first irradiation element disposed on the bottom surface between each of the fixed seats, several sliding seats movably sleeved on the right side of the two crossbeams, a second irradiation element disposed on the bottom surface between each of the sliding seats, and a first telescopic device disposed laterally on one of the sliding seats on the right side of each of the sliding seats.

[0010] A further improvement is that the sterilization plate box assembly includes a sterilization plate box, a sterilization chamber connected to both sides of the top surface of the sterilization plate box, and a storage chamber. The sterilization chamber and the storage chamber are isolated by a lifting gate. A connecting seat is hinged to the right end of the sterilization plate box. Several vibrators are provided on the front and rear sides of the sterilization plate box. A pusher box telescopic device is hinged to the left end of the bottom surface of the sterilization plate box. A bottom pad is longitudinally provided on the left side of the bottom surface of the sterilization plate box.

[0011] A further improvement is that a storage chamber cover is hinged to the top surface of the storage chamber, and a discharge port is opened on the bottom surface of the storage chamber.

[0012] A further improvement is that the pushing mechanism includes a lead screw and a slide bar, and a pushing plate assembly is longitudinally movable between the lead screw and the slide bar, and a motor is driven to one side of the lead screw.

[0013] A further improvement is that the pusher plate assembly includes a pusher frame, slide seats and screw moving seats located on the front and rear sides of the top of the pusher frame, and a pusher plate located at the lower right side of the pusher frame. The right side of the pusher plate has an arc-shaped pusher groove, and the pusher plate is made of plastic.

[0014] A further improvement is that the filling box assembly includes a filling box, a discharge box pipe disposed on the bottom front surface of the filling box, a swing hose connected to the lower end of the discharge box pipe, and a filling head connected to the lower end of the swing hose. The filling head is provided with a first valve, a fixing frame is installed on one side of the filling head, and a sliding inclined plate is disposed on the bottom surface of the discharge box pipe cavity.

[0015] A further improvement is that when the pushing mechanism pushes the sterilization tray box assembly to the right, the pusher box telescopic device needs to extend to push the sterilization tray box to tilt 10-15 degrees, with the left side higher than the right side.

[0016] A further improvement is that the metering mechanism is connected to an external feeding pipe.

[0017] A further improvement is that an external filling conveyor belt is horizontally arranged below the front end of the filling box assembly.

[0018] A further improvement is that the first irradiation element, the second irradiation element, and the lifting gate are existing technologies, and their structures will not be described in detail here.

[0019] Furthermore, the present invention also provides a processing method for the above-mentioned irradiation sterilization equipment for ready-to-eat food, the processing method being as follows:

[0020] First, the external feeding pipe feeds the metering tank. During this process, all vibrators need to be activated to transmit vibrations to the metering tank, ensuring the material inside is leveled. When the material rises to the correct position and is detected by the sensor, the metering is completed. Then, the first telescopic device on the irradiation assembly extends to the right, causing the second irradiation element to slide to the right via the sliding seats, opening a downward feeding channel. The telescopic device then extends downward, driving the discharge nozzle through the feeding channel to the top of the sterilization chamber. The valve then opens, allowing the material in the metering tank to enter the sterilization chamber through the feeding pipe, telescopic pipe, and discharge nozzle. During this process, all vibrators need to be activated to uniformly feed the material in the sterilization chamber and prevent jamming during metering. The metering mechanism then rises back to its original position, and the irradiation assembly returns to its original position, closing the feeding channel. Then, the first and second irradiation elements... The raw materials, after being leveled, undergo irradiation sterilization above the sterilization chamber. Once the irradiation sterilization time is reached, the first and second irradiation units are closed, and then the lifting gate opens to connect the sterilization chamber with the storage chamber. Subsequently, the pusher plate assembly on the pushing mechanism, driven by a motor, rotates the lead screw and, with the assistance of the sliding rod, pushes the material from left to right within the sterilization chamber. During this process, the pusher box telescopic device needs to extend upwards, tilting the sterilization plate box left-high and right-low to coordinate with the pusher plate's pushing action, preventing material accumulation during pushing. During pushing, the raw materials flow sequentially into the storage chamber and finally into the filling box for temporary storage through the discharge outlet. When the sterilization plate box is tilted, the filling box assembly is also activated, but the filling head is not activated by the swing hose, allowing the filling head to continue filling the packaging boxes conveyed by the external filling conveyor belt without pausing.

[0021] The beneficial effects of the invention are:

[0022] This invention provides a method and equipment for irradiation sterilization of ready-to-eat foods. Through the structural combination design of a quantitative mechanism, irradiation components, sterilization plate and box assembly, material pushing mechanism, and filling box assembly on an irradiation sterilization chamber, a ready-to-eat food processing irradiation sterilization equipment is constructed. This equipment integrates relative quantitative irradiation, leveling and spreading of quantitative raw materials, irradiation sterilization, tilting auxiliary material pushing, temporary storage of raw materials, and continuous filling. The equipment of this invention features short irradiation sterilization time, timely and uninterrupted filling of sterilized raw materials, optimized process, simple operation, and high work efficiency.

[0023] The design of the quantitative mechanism assists the sterilization plate box assembly in relative quantitative measurement. The quantitative measurement can accept a certain error value and will not affect the irradiation sterilization of the irradiation components, so that the raw materials after vibration and flattening of the sterilization plate box assembly are roughly the same for each batch.

[0024] The irradiation component is designed to allow for irradiation sterilization of the sterilization plate box assembly, while also having a centrally open feeding channel. This allows the feeding mechanism to extend downwards, reducing the distance between the feeding mechanism and the sterilization chamber and preventing raw material splashing during feeding.

[0025] The design of the sterilization plate box assembly includes various vibrators that, while leveling themselves, can also transmit certain shock waves to the metering mechanism and filling box assembly, which can solve the problem of material jamming during feeding or filling. In addition, the tilt angle function can assist the pushing mechanism in pushing the material into the filling box assembly. Under the action of the tilt angle, the pushing mechanism will not accumulate material.

[0026] The design of the filling tank assembly allows the filling to extend to the front of the irradiation sterilization chamber, enabling the filling to be externally integrated into an automated assembly line. In addition, the design of the swing hose ensures that when the filling tank assembly is tilted and swung in conjunction with the sterilization plate assembly, the filling head is not affected and the filling operation can continue without interruption.

[0036] Working principle:

[0037] First, the external feed pipe feeds the metering tank 21. During this process, each vibrator 46 needs to be turned on to transmit some vibration waves to the metering tank 21, so that the raw material inside the metering tank 21 can be leveled. When the raw material rises to the position and is sensed by the sensor 28, the metering is completed. Then, the first telescopic device 36 on the irradiation assembly 3 extends to the right, and through each sliding seat 34, it causes the second irradiation element 35 to slide to the right, opening a downward feeding channel. Then, the telescopic device 27 extends downward, driving the discharge nozzle 26 through the feeding channel to reach the irradiation chamber. Above the sterilization chamber 42, valve 24 is opened, allowing the raw material in the metering tank 21 to enter the sterilization chamber 42 through the feed pipe 23, telescopic pipe 25, and discharge nozzle 26. During this process, each vibrator 46 needs to be activated to uniformly sterilize the raw material in the sterilization chamber 42. This also serves to prevent material jamming during feeding into the metering tank 21. Then, the metering mechanism 2 rises to its original position, and the irradiation assembly 3 returns to its original position to close the feed channel. Then, the first irradiation element 33 and the second irradiation element 35 are aligned above the sterilization chamber 42 after leveling. The raw materials undergo irradiation sterilization. After the irradiation sterilization time is reached, the first irradiation element 33 and the second irradiation element 35 are closed. Then, the lifting gate 44 opens to connect the sterilization chamber 42 with the storage chamber 43. Subsequently, the pusher plate assembly 53 on the pusher mechanism 5 drives the lead screw 51 to rotate via the motor 54 and, with the cooperation of the slide rod 52, pushes the pusher plate 534 from left to right within the sterilization chamber 42. During this process, the pusher box telescopic device 47 needs to extend upwards to tilt the sterilization plate box 41 left-high and right-low to cooperate with the pusher plate 534. In this invention, the sterilization tray 41 is tilted at an angle of 11-12 degrees to prevent the raw materials from piling up during the feeding process. During feeding, the raw materials will flow into the storage chamber 43 in sequence and finally into the filling box 61 through the discharge port 432 for temporary storage. When the sterilization tray 41 is tilted, the filling box assembly 6 will also be linked, but under the action of the swing hose 63, the filling head 64 will not be linked, so that the filling head 64 can continue to fill the packaging boxes conveyed by the external filling conveyor belt without pausing.

[0038] To clean the sterilization tray 41 and the filling tray 61, simply open the cleaning box door 11 and the storage chamber cover 431.

When the raw material rises to the position and is sensed by the sensor (28), the metering is completed. Then, the first telescopic device (36) on the irradiation assembly (3) extends to the right and slides to the right through each sliding seat (34) to open a downward feeding channel. Then, the telescopic device (27) extends downward to drive the discharge nozzle (26) through the feeding channel. The feed pipe reaches the top of the sterilization chamber (42), and then the valve (24) is opened, allowing the raw material in the metering tank (21) to enter the sterilization chamber (42) through the feed pipe (23), the telescopic pipe (25), and the discharge nozzle (26).
