Description

Technical Field

[0001] This application relates to the field of pet food processing technology, specifically to a movable storage tank that can be heated, vented, and quantitatively injected. Background Technology

[0002] In the pet food processing industry, wet food (such as canned and bagged wet food) is widely favored by consumers due to its rich nutrition and palatability. However, product quality problems often arise during the production of wet food due to process defects, especially the frequent occurrence of bulging cans and bags, which seriously affects the product's shelf life and market reputation. Currently, wet food production mainly adopts an atmospheric pressure chopping process, where materials are directly poured into packaging containers after chopping. However, in this process, air inevitably remains inside the can. During subsequent heat sterilization, the residual air expands due to heat, causing the packaging container to deform or even rupture, resulting in bulging cans or bags. Statistics show that the incidence of such problems is as high as 15-20%, not only causing a large amount of product waste but also increasing the production costs of enterprises.

[0003] In existing technologies, some companies have adopted vacuum grouting equipment to address the issue of residual air. This type of equipment removes air from the material through a vacuum environment, which alleviates the problem of can bulging to some extent. However, the equipment is fixed, has high investment costs (typically over 300,000 yuan per unit), and is difficult to adapt flexibly to the needs of different production lines. Furthermore, vacuum equipment is complex to maintain and requires extremely high sealing of the production environment, further increasing operating costs. Another solution relies on manual venting, which involves manually removing air from the can. However, this method is inefficient (reducing capacity by about 30%), and the venting effect is unstable, making it difficult to completely solve the problem. Manual operation also introduces risks related to hygiene and consistency.

[0004] Furthermore, existing storage tanks have low precision in the quantitative grouting process (error of approximately ±5%), resulting in inconsistent product filling volumes, which negatively impacts consumer experience and corporate brand image. The design of fixed equipment limits the flexibility of the production line, failing to meet the demands of multi-variety, small-batch production. Especially in scenarios requiring frequent production line changes, the immobility of the equipment becomes a bottleneck restricting production efficiency. Utility Model Content

[0008] Furthermore, a second motor is fixedly installed on the tank lid, and a stirring rod is driven to the output end of the second motor. The stirring rod is located in the storage tank.

[0009] Furthermore, the rotary grouting head includes a main pipe, which is fixedly connected to the discharge pipe. A switching disc is connected to the lower end of the main pipe, and the switching disc can rotate at the lower end of the main pipe. A bag-filling nozzle and a can-filling nozzle are installed below the switching disc. The outlet of the bag-filling nozzle is flat, and the outlet of the can-filling nozzle is round.

[0010] Furthermore, the main pipe is provided with a main channel, and two identical through holes are symmetrically opened on the switching plate.

[0011] Furthermore, the edge of the switching disk is provided with an annular groove, and two cylinders are fixed in the annular groove. The two cylinders are located on one side of the two through holes respectively. A compression spring is installed on each of the two cylinders. One end of the compression spring is fixed to the cylinder, and the other end of the compression spring is fixed to a ball. A docking groove is provided on the main connecting pipe, and a docking hole is provided on the docking groove.

[0012] Furthermore, there are four hydraulic lifting outriggers, which are respectively installed at the four corners of the base plate. Each hydraulic lifting outrigger is equipped with a caster wheel at its output end, and each caster wheel is equipped with a brake pedal.

[0013] Furthermore, a push-pull handle is installed on one side edge of the base plate, and the outer surface of the grip section of the push-pull handle is covered with an anti-slip rubber sleeve.

[0017] 3.

[0020] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] like Figures 1-4 As shown, in order to address the above-mentioned problems, this application provides a movable storage tank with heating, steam exhaust, and quantitative grouting capabilities, including a movable bracket on which a quantitative grouting module and a heating, steam exhaust module are installed.

[0022] The aforementioned movable support includes a base plate 11, which is a rectangular flat plate structure. Four hydraulic lifting legs 12 are installed below the base plate 11, with each leg mounted at one of the four corners of the lower surface of the base plate 11. The output ends of the hydraulic lifting legs 12 point vertically downwards. Each hydraulic lifting leg 12 has a caster wheel 13 installed at its output end, and each caster wheel 13 is equipped with a brake pedal. During operation or when not in use, the brake pedal can be pressed to lock the caster wheel 13 and prevent accidental slippage.

[0023] A push-pull handle 14 is installed on one edge of the base plate 11, and the outer surface of the grip section of the push-pull handle 14 is covered with an anti-slip rubber sleeve. A control box 15 is fixedly installed on one side of the base plate 11. The control box 15 contains a controller, and a touch screen 16 is installed on the top of the control box 15. The touch screen 16 is connected to the controller via electrical wiring. A power plug is connected to the controller. After the power plug is connected to an external power source, the equipment can operate. A mounting frame 17 is fixedly installed on the other side of the base plate 11. The mounting frame 17 is a rectangular three-dimensional frame. The grouting module is fixedly installed on the mounting frame 17.

[0024] The aforementioned grouting module includes a storage tank 21, which is fixedly mounted on the mounting frame 17. The storage tank 21 is filled with processed wet pet food. An upper opening is provided at the top of the storage tank 21, and a lid 22 is installed at the upper opening. A semi-circular inlet is provided on the lid 22, and an upward-opening door 23 is hinged to the lid 22 to close the inlet. A discharge port is provided at the bottom of the storage tank 21, and a plunger pump 24 is installed below the storage tank 21. A discharge pipe 25 is fixedly connected between the plunger pump 24 and the storage tank 21.

[0025] A servo motor 29 is connected to one side of the plunger pump 24, which can drive the plunger pump 24 to work. The discharge port of the plunger pump 24 is connected to a discharge pipe 26, and a high-precision flow sensor 27 is fixedly connected to the discharge pipe 26. Both the servo motor 29 and the high-precision flow sensor 27 are connected to the controller through electrical circuits.

[0026] like Figures 6-8 As shown, a rotary grouting head 28 is installed at the end of the discharge pipe 26. The rotary grouting head 28 includes a main pipe 2801, which is fixedly connected to the discharge pipe 26. A main channel 2802 is provided inside the main pipe 2801. A switching disc 2803 is connected to the lower end of the main pipe 2801, and the switching disc 2803 can rotate at the lower end of the main pipe 2801.

[0027] Two identical through holes 2804 are symmetrically arranged along the central axis of the switching disk 2803. The diameter of the through holes 2804 is the same as the inner diameter of the main channel 2802, and both through holes 2804 can connect to the main channel 2802. A bag-filling nozzle 2805 and a can-filling nozzle 2806 are installed below the switching disk 2803, and both nozzles connect to the two through holes 2804 respectively. The outlet of the bag-filling nozzle 2805 is flat, and the outlet of the can-filling nozzle 2806 is circular.

[0028] The switching disk 2803 has an annular groove 2807 on its edge. Two cylinders 2808 are fixed within the annular groove 2807, perpendicular to the circumference of the groove. Each cylinder 2808 is located on one side of one of the two through holes 2804. A compression spring 2809 is mounted on each cylinder 2808, with one end fixed to the cylinder and the other end fixed to a ball 2810. The main connector 2801 has an annular mating groove on its circumference, with a mating hole 2811 located on the flow channel outlet side. The diameter of the mating hole 2811 is slightly smaller than the diameter of the ball 2810, allowing the ball 2810 to be inserted into it. When inserted, a portion of the ball 2810 protrudes from the hole.

[0029] When the main connector 2801 is assembled with the switching disc 2803, the compression spring 2809 and the ball 2810 are located in the annular groove 2807, and the compression spring 2809 is in a compressed state. Rotating the switching disc 2803, when the bag nozzle 2805 or can nozzle 2806 is fully aligned with the main channel 2802, the compression spring 2809 releases its elasticity, pushing the ball 2810 towards the docking hole 2811 and locking it into the docking hole 2811. When switching nozzles, pressing down on the portion of the ball 2810 extending out of the docking hole 2811 forces the ball 2810 and the compression spring 2809 back into the annular groove 2807, releasing the positioning. At this time, the switching disc 2803 can be rotated to align the other through hole 2804 with the main channel 2802, and the spring again pushes the ball 2810 out and locks it into the docking hole 2811, completing the nozzle switching.

[0030] Example 1: The plunger pump 24 draws wet grain from the storage tank 21. The wet grain is then conveyed through the discharge pipe 26 to the rotary grouting head 28 for dispensing. During the conveying process, the high-precision flow sensor 27 monitors the wet grain flow rate in real time and transmits the data to the controller. The controller compares the actual flow rate with the preset value and then adjusts the speed of the servo motor 29 driving the plunger pump 24, thereby changing the delivery volume of the plunger pump 24 and ultimately achieving precise control of the grouting volume. During dispensing, the bag-filling nozzle 2805 or the can-filling nozzle 2806 of the rotary grouting head 28 can be switched to adapt to different packaging specifications.

[0031] like Figures 1-3As shown, the aforementioned heating and exhaust module includes a heating belt embedded in the inner wall of the storage tank 21 to heat the wet pet food inside. A temperature sensor is installed on the storage tank 21 to detect the temperature of the wet pet food. A negative pressure exhaust fan 31 is mounted on one side of the storage tank 21, and a gas supply pipe 32 connects the negative pressure exhaust fan 31 to the storage tank 21, allowing it to communicate with the internal space of the storage tank 21. A multi-stage condenser 35 is connected in series on the gas supply pipe 32 between the storage tank 21 and the negative pressure exhaust fan 31. The heating belt, the negative pressure exhaust fan 31, and the multi-stage condenser 35 are all connected to the controller via electrical wiring.

[0032] Example 2: After the pet wet food is added through the feed inlet of the storage tank 21, the top door 23 is closed to keep the storage tank 21 in a relatively sealed state. Then, the wet food in the storage tank 21 is heated by the electric heating belt to control the temperature of the wet food at 50-80℃. This temperature range can promote the full escape of the air carried in the wet food and avoid destroying the nutritional components of the wet food.

[0033] Simultaneously, the negative pressure steam extractor 31 is activated. The negative pressure steam extractor 31 draws air from the inside of the storage tank 21 through the gas delivery pipe 32, creating a stable negative pressure environment. Under the combined action of heating and negative pressure, the air, volatile flavor substances, and water vapor escaping from the wet grain mix to form a mixed gas. This mixed gas flows along the gas delivery pipe 32 to the negative pressure steam extractor 31, first passing through a multi-stage condenser 35 connected in series with the gas delivery pipe 32. The multi-stage condenser 35 gradually cools the mixed gas, causing the water vapor and volatile flavor substances in the mixed gas to condense into liquid. These liquid substances flow back to the storage tank 21 through the return pipe on the multi-stage condenser 35 for recovery, preventing flavor and moisture loss. The remaining non-condensable gases (mainly oxygen) in the mixed gas are extracted from the system by the negative pressure steam extractor 31, reducing the residual oxygen content of the wet grain in the storage tank 21 to a low level. This completes the wet grain steam removal process, preventing problems such as tank or bag bulging during subsequent filling.

[0034] like Figure 5 As shown, a second motor 33 is fixedly installed on the can lid 22, and the second motor 33 is connected to the controller via electrical wiring. A stirring rod 34 is driven to the output end of the second motor 33. The stirring rod 34 is located in the storage tank 21. During the heating process, the second motor 33 can drive the stirring rod 34 to rotate in the storage tank 21, so that the wet grain is heated evenly.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
