Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to an automatic mixing device for pet food ingredients. Background Technology

[0002] Pet food is a high-end animal food specifically designed for pets and small animals, falling between human food and traditional livestock feed. Its main function is to provide various pets with the most basic nutrients needed for life, growth, development, and health. It has advantages such as comprehensive nutrition, high digestibility and absorption rate, scientific formula, quality standards, convenient feeding and use, and the ability to prevent certain diseases.

[0003] Existing mixing devices typically deploy equipment in low-temperature workshops (ambient temperature 2-8℃) or use pre-cooled raw materials to meet initial temperature control conditions. However, during the mixing process, the moving parts such as the stirring blades and transmission mechanisms inside the device generate heat due to mechanical friction. This heat is conducted through the metal cavity and materials, causing the local raw material temperature to exceed the safety threshold. This has a particularly serious impact on heat-sensitive raw materials such as meat and probiotics, causing meat proteins to denature more rapidly in a high-temperature environment, thus affecting food quality and safety. Therefore, an automatic mixing device for pet food raw materials is proposed. Utility Model Content

[0032] Example 1

[0033] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an automatic mixing device for pet food ingredients. The mixing tank can be temperature controlled throughout by a hollow column and a tank cooling unit to prevent the ingredients from deteriorating due to abnormal temperature. The device includes a mixing unit 100, a central cooling unit 200 and a tank cooling unit 300.

[0034] The mixing unit 100 includes a mixing tank 101 and a feed pipe 102 fixedly connected to its top. A discharge pipe 103 is fixedly connected to the bottom of the mixing tank 101. An electric control valve is sleeved on the discharge pipe 103. A stirring assembly 104 for mixing raw materials is provided inside the mixing tank 101.

[0035] The central cooling unit 200 installed in the mixing tank 101 includes a hollow column 201 installed at the center of the mixing tank 101. The bottom of the hollow column 201 is fixedly connected to an inlet pipe 202 and an outlet pipe 203. An electric control valve is sleeved on the wall of the outlet pipe 203. The bottom ends of the inlet pipe 202 and the outlet pipe 203 both penetrate the bottom of the mixing tank 101.

[0036] A tank cooling unit 300 is installed inside the mixing tank 101. The tank cooling unit 300 is connected to the liquid inlet pipe 202 and is used to cool the mixing tank 101.

[0037] The feed pipe 102 is used to connect to external food supply equipment. Pet food raw materials enter the mixing tank 101 through the feed pipe 102. The stirring component 104 stirs and mixes the raw materials. The mixed raw materials are discharged through the discharge pipe 103 and the electric control valve. During the mixing process, the liquid inlet pipe 202 and the liquid outlet pipe 203 are connected to the circulating refrigeration equipment. Cooling liquid flows from the liquid inlet pipe 202 into the hollow column 201, cools the raw materials in the central area of ​​the mixing tank 101, and then flows out from the liquid outlet pipe 203. The heated cooling liquid is cooled by the external refrigeration equipment and then flows back into the liquid inlet pipe 202. The tank cooling unit 300 is connected to the liquid inlet pipe 202. The cooling liquid transported by the liquid inlet pipe 202 is used to cool the mixing tank 101. Thus, during the raw material mixing process, the dual cooling structure maintains a low temperature environment and prevents the raw materials from deteriorating.

[0038] Example 2

[0039] Reference Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the stirring assembly 104 includes a servo motor 104a fixedly installed on the top of the mixing tank 101. The output shaft of the servo motor 104a rotates through the mixing tank 101 and is fixedly connected to a support plate 104b. Two stirring rods 104c are fixedly connected to the bottom of the support plate 104b.

[0040] When the servo motor 104a is powered on, the rotational motion of the output shaft is directly transmitted to the support plate 104b, driving it to rotate synchronously. The two stirring rods 104c are vertically fixed to the bottom of the support plate 104b and rotate synchronously with the support plate 104b. The stirring rods 104c rotate around the hollow column 201 and generate radial thrust and shear force on the raw materials in the mixing tank 101 during the rotation, forcing them to mix.

[0041] The bottom of the mixing tank 101 is tapered downwards, causing the raw materials to gather towards the discharge pipe 103 under the action of gravity, ensuring that all raw materials are discharged smoothly. The bottoms of the two stirring rods 104c are fixedly connected to inclined plates 104d that fit with the conical surface of the mixing tank 101.

[0042] The inclined plate 104d at the bottom of the stirring rod 104c is in contact with the conical surface of the mixing tank 101 to stir the raw materials near the conical surface upwards, ensuring that the raw materials near the conical surface are mixed evenly.

[0043] Example 3

[0044] Reference Figure 4 This is the third embodiment of the present invention. Unlike the previous embodiment, the hollow column 201 has a partition 204 fixedly connected to the inner cavity along the axis, and the top of the partition 204 and the top of the inner cavity of the hollow column 201 are left with a liquid passage gap.

[0045] The top of the hollow column 201 is dome-shaped and protrudes upwards, which can effectively prevent raw materials from accumulating on the top of the hollow column 201. The baffle 204 arranged along the axis of the inner cavity of the hollow column 201 divides its internal space into two independent flow channels. After the coolant flows in from the inlet pipe 202, it flows upwards along the flow channel on one side of the baffle 204. At the top, it merges with the liquid at the top of the inner cavity of the hollow column 201 through the gap, and then flows out from the drain pipe 203, so that the coolant forms a circulating flow path in the hollow column 201, avoiding direct mixing of the coolant and the heated coolant, thus ensuring the efficient recycling of the coolant.

[0046] Example 4

[0047] Reference Figure 2 and Figure 3 This is the fourth embodiment of the present invention. Unlike the previous embodiment, the inner wall of the mixing tank 101 is hollow, forming a sandwich space for the flow of coolant. The tank cooling unit 300 includes a supply pipe 301 and an outlet pipe 302. One end of the supply pipe 301 is connected to the inlet pipe 202, and the other end is connected to the top of the side wall of the mixing tank 101. The outlet pipe 302 is connected to the bottom of the side wall of the mixing tank 101 and is equipped with an electric control valve.

[0048] Coolant is diverted from inlet pipe 202 to supply pipe 301, and then flows into the jacket from the top of the side wall of mixing tank 101. After completing the heat exchange of the tank wall and internal raw materials of mixing tank 101, coolant flows out from outlet pipe 302 at the bottom of the side wall. The electric control valve controls the opening and closing of outlet pipe 302 to realize the on / off control of coolant circulation path. Outlet pipe 302 is also connected to circulating refrigeration equipment to continuously cool mixing tank 101.

[0049] Electric flow regulating valves 303 are installed on the walls of both the inlet pipe 202 and the supply pipe 301 to control the liquid flow rate of the inlet pipe 202 and the supply pipe 301 respectively.

[0050] The electric flow regulating valves 303 installed on the inlet pipe 202 and the supply pipe 301 can precisely regulate the flow rate of coolant in their respective pipes. When the temperature in the central area of ​​the mixing tank 101 is high, the flow rate of the inlet pipe 202 can be increased. If the temperature near the tank wall rises significantly, the flow rate of the supply pipe 301 can be increased, thereby achieving differentiated cooling and temperature control for different areas of the mixing tank 101.

[0051] In addition, a spiral blade 304 is fixedly connected to the hollow part of the inner wall of the mixing tank 101 to change the flow path of the coolant in the jacket. The supply pipe 301 and the outlet pipe 302 are staggered from the spiral blade 304.

[0052] This causes the coolant to flow down the spiral blades 304 after flowing into the jacket from the supply pipe 301, until it flows out from the outlet pipe 302 at the bottom. This spiral flow method prolongs the residence time of the coolant in the jacket, increases the contact area and contact time between the coolant and the tank wall of the mixing tank 101, and thus removes the heat of the mixing tank 101 more efficiently.

[0053] It should be noted that the pitch of the spiral blade 304 decreases from bottom to top, and the side of the spiral blade 304 is reinforced and connected to the inner wall interlayer of the mixing tank 101 by welding or riveting.

[0054] When the coolant flows into the jacket, due to the large pitch at the bottom, the coolant flow space is relatively spacious and the flow rate is relatively slow. This allows the coolant to fully absorb the heat generated at the bottom of the mixing tank 101 due to the accumulation of raw materials, thereby balancing the temperature difference at different heights within the tank and preventing unbalanced cooling. At the same time, the sides of the spiral blades 304 are reinforced and connected to the inner wall jacket of the mixing tank 101 to ensure that it remains stable under the conditions of coolant scouring and tank vibration, thus maintaining a stable flow guiding effect.

[0055] During use, the external food supply equipment delivers pet food raw materials to the mixing tank 101 through the feed pipe 102. Then, the servo motor 104a drives the support plate 104b and the stirring rod 104c to rotate, mixing the raw materials. The conical structure at the bottom of the mixing tank 101, together with the inclined plate 104d, guides the raw materials to flow towards the discharge pipe 103 and prevents material accumulation. At the same time, the circulating refrigeration equipment delivers coolant to the hollow column 201 through the liquid inlet pipe 202. The coolant circulates in the flow channels separated by the partition 204 to remove heat from the central area of ​​the mixing tank 101. Then, the coolant flows back and is discharged through the liquid outlet pipe 203.

[0056] Meanwhile, the coolant can be diverted from the inlet pipe 202 to the supply pipe 301 and enter the inner wall interlayer of the mixing tank 101. Guided by the spiral blade 304, it flows downward in a spiral to exchange heat with the tank wall of the mixing tank 101 before flowing back out through the outlet pipe 302. The flow distribution of the inlet pipe 202 and the supply pipe 301 can be adjusted according to the temperature of each area by two electric flow regulating valves 303. The mixed raw materials are discharged under the control of the electric control valve of the discharge pipe 103.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
