Description

Technical Field

[0001] This utility model relates to the field of food sterilization technology, and in particular to an energy-saving food sterilization device. Background Technology

[0002] Water bath sterilization tanks are commonly used sterilization equipment in the food processing industry. Their core principle is to place food in a sealed tank filled with high-temperature hot water (usually water or steam condensate), utilizing the high temperature of the hot water to destroy the cell structure of microorganisms, thereby killing bacteria, mold, and other harmful microorganisms. This type of equipment is widely used in the sterilization of canned goods, beverages, vacuum-packed foods, and other products. It features simple operation and easy temperature control, achieving uniform heating of food through the heat conduction of the hot water. It is one of the key pieces of equipment for ensuring food shelf life and safety.

[0003] When using water bath sterilization tanks, we found that the heating and cooling systems of traditional devices are independent. The heated water is directly cooled or discharged after sterilization without effective recycling. The low-temperature water used in the cooling stage absorbs heat and then heats up, and is also directly discarded, resulting in a large amount of heat energy loss, increasing production energy consumption and costs. Most of the equipment lacks an effective stirring or turning structure, and the hot water is prone to temperature stratification in the tank, resulting in uneven heating during the food sterilization process.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, an energy-saving food sterilization device includes a sterilization mechanism 1, a heating mechanism 3 on the left side of the sterilization mechanism 1, and a cooling mechanism 2 on the right side of the sterilization mechanism 1.

[0024] In this embodiment, the sterilization mechanism 1 includes a sterilization tank 101, a rotating assembly 102, a limiting mechanism 103, and a material rack 104. The rotating assembly 102 is disposed around its outer periphery inside the sterilization tank 101. Multiple limiting mechanisms 103 are disposed at the front end of the rotating assembly 102. The material rack 104 is disposed around its outer periphery inside the rotating assembly 102 via a bracket. The rotating assembly 102 includes a rotating cylinder 1021, limiting rollers 1022, limiting rings 1023, a gear ring 1024, a gear 1025, and a reduction motor 1026. The limiting rollers 1022 are installed on the inner side wall of the sterilization tank 101. The limiting rings 1023 are fixedly connected to the outer periphery of the rotating cylinder 1021 at their center. The outer periphery of the rotating cylinder 1021 is installed inside the sterilization tank 101 via the limiting rollers 1022 and the limiting rings 1023. The gear ring 1024 is fixedly connected to the front end of the rotating cylinder 1021 at its middle part, and the gear 1025 is rotatably connected to the upper part of the sterilization tank 101 at its middle part. The gear motor 1026 is installed on the upper part of the sterilization tank 101, and the output end of the gear motor 1026 is fixedly connected to the middle of the gear 1025. The gear 1025 and the gear ring 1024 mesh with each other. The material rack 104 is set inside the rotating cylinder 1021 through a bracket on its outer periphery. Multiple baffles 1027 are installed at equal intervals on the wall shell of the rotating cylinder 1021. The limiting mechanism 103 includes a baffle 1031, a knob 1033 and a bolt 1032. One end of the baffle 1031 is rotatably connected to the outer periphery of the bolt 1032, one end of the bolt 1032 is fixedly connected to the middle of the knob 1033, and the other end of the bolt 1032 is threadedly connected to the front part of the gear ring 1024.

[0025] Specifically, the material rack 104 is composed of multiple sub-material racks and a top cover plate stacked together, and a frame for fixing materials is placed inside it. The placement slots inside the frame are adapted to the size of the materials to prevent large displacement of the materials during rotation. The outer circumference of the material rack 104 is adapted to the size of the support on the inner wall of the rotating cylinder 1021. The upper support on the inner wall of the rotating cylinder 1021 presses down on the uppermost sub-material rack 104 and the cover plate, and the lower support on the inner wall of the rotating cylinder 1021 supports the material rack 104, so that the material rack 104 will not wobble significantly on the support when the rotating cylinder 1021 rotates, preventing it from detaching from the support of the rotating cylinder 1021 and allowing it to slide out smoothly.

[0026] In this embodiment, the cooling mechanism 2 includes a cooling tank 201, two cooling connecting pipes 202 (front and rear), a plate heat exchanger 203, a delivery pump, and a solenoid valve. The solenoid valve is installed in the middle of the cooling connecting pipe 202. One end of the front cooling connecting pipe 202 is installed at the front end of the cooling tank 201, and the other end is installed at the front end of the sterilization tank 101. One end of the rear cooling connecting pipe 202 is installed at the rear end of the cooling tank 201, and the other end is installed at the rear end of the sterilization tank 101. One of the cooling connecting pipes 202 is connected to the plate heat exchanger 203 in the middle. The delivery pump is installed on one of the cooling connecting pipes 202 near one end of the cooling tank 201 and is installed inside the cooling tank 201. The heating mechanism 3 includes a heat storage device. The tank 301, heating connection pipe 302, steam heating component 303, delivery pump, and solenoid valve are included. The solenoid valve is installed in the middle of the heating connection pipe 302. One end of the front heating connection pipe 302 is installed at the front end of the heat storage tank 301, and the other end is installed at the front end of the sterilization tank 101. One end of the rear heating connection pipe 302 is installed at the rear end of the heat storage tank 301, and the other end is installed at the rear end of the sterilization tank 101. The delivery pump is installed on one of the heating connection pipes 302 near one end of the heat storage tank 301 and is installed inside the heat storage tank 301. Sensor components are installed on the inner walls of the sterilization tank 101, cooling tank 201, and heat storage tank 301. The sensor components are electrically connected to an external terminal.

[0027] Specifically, the sensor components include, but are not limited to, level sensors, pressure sensors, and temperature sensors. These are added according to actual production needs. During operation, the level sensors, pressure sensors, and temperature sensors monitor the water level, temperature, and pressure in each tank in real time, and then convert the data into electrical signals to transmit to external terminals, ensuring the safe and stable operation of the equipment.

[0028] Working principle:

[0029] The food to be sterilized is placed on the material rack 104, and then the material racks 104 are placed sequentially on the support on the inner wall of the rotating cylinder 1021, ensuring that adjacent material racks 104 abut against each other. Rotating the knob 1033 drives the bolt 1032 to rotate, causing the knob 1033 to press the baffle 1031 against the front end of the gear ring 1024. The baffle 1031 abuts against the front end of the material rack 104, preventing it from wobbling back and forth during subsequent processes. After starting the device, the reduction motor 1026 drives the gear 1025 to rotate. The gear 1025 meshes with the gear ring 1024, driving the rotating cylinder 1021 of the rotating assembly 102 to rotate inside the sterilization tank 101. The limiting roller 1022 and the limiting ring 1023 cooperate to ensure the stable operation of the rotating cylinder 1021. The baffle 1027 on the rotating cylinder 1021 rotates with it, agitating the fluid inside the tank. The reduction motor 1026... While in operation, the heating mechanism 3 is activated, and the steam heating component 303 heats the water in the heat storage tank 301. The delivery pump pumps the hot water into the sterilization tank 101 through the heating connection pipe 302, so that the hot water submerges the material and realizes the circulation of hot water between the heat storage tank 301 and the sterilization tank 101. The heat of the hot water completes the sterilization treatment of the material. After sterilization, the heating mechanism 3 pumps the hot water in the sterilization tank 101 back to the heat storage tank 301. Then the cooling mechanism 2 is activated, and the cooling water in the cooling tank 201 enters the sterilization tank 101 through the delivery pump and the cooling connection pipe 202, forming a circulation to cool the sterilization tank 101 and the material inside. One of the cooling connection pipes 202 has a plate heat exchanger 203 that recovers waste heat from the heated cooling water, reducing the temperature of the cooling water while recovering heat energy to achieve energy saving. After cooling is completed, the device is turned off, and the limit mechanism 103 is reversed to remove the baffle 1031, so that the material rack 104 and the sterilized food can be taken out.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
