Description

Technical Field

[0001] This utility model belongs to the field of pie processing technology, specifically relating to a filling mixing device for pie production. Background Technology

[0002] In the food processing industry, especially in the production of pie fillings, traditional mixing devices generally suffer from low mixing efficiency and high energy consumption. Existing equipment often uses single-spiral blades or simple mixing structures, leading to layering of the filling during mixing. The material in the center area is not evenly mixed with the edges, affecting the consistency of the product's texture. Furthermore, material often remains at the bottom of the mixing tank because the blades cannot fully adhere, resulting in waste and potentially bacterial growth, threatening food safety.

[0003] To address these issues, some improvement solutions attempt to enhance mixing by increasing the number of stirring shafts or optimizing blade shape. However, such designs often result in complex structures, increased maintenance costs, and do not fundamentally solve the problem of residue at the bottom. Utility Model Content

[0004] The purpose of this invention is to provide a filling mixing device for pie production, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A filling mixing device for pie production includes a cylindrical mixing box with a discharge port at the bottom and a filling port, a liquid injection port, and an exhaust port at the top; a mixing motor connected to the mixing box; and a double-helix mixing mechanism located inside the mixing box, including a first helix mixing blade, a second helix mixing blade, a mixing shaft, a connecting rod, and a scraper. The first and second helix mixing blades are arranged alternately and parallel to each other, with their upper and lower ends connected by scrapers and connected at the same position in the middle by a connecting rod. The bottom of the scraper is always in contact with the bottom of the mixing box.

[0007] Preferably, the bottom of the mixing tank is a flat structure, and the bottom surface of the scraper is completely in contact with the bottom of the mixing tank.

[0008] Preferably, a butterfly valve is installed at the discharge port, and the valve plate of the butterfly valve is flush with the bottom of the mixing tank.

[0009] Preferably, the first and second helical stirring blades have opposite helical directions and the same pitch.

[0010] Preferably, the top end of the stirring shaft is fixedly connected to the output shaft of the stirring motor, and the bottom end is rotatably connected to the bottom of the mixing tank through a bearing.

[0011] The beneficial effects of this invention are as follows: Through the synergistic design of the double-helix stirring mechanism and the scraper, this invention significantly improves the uniformity of filling mixing. The double-helix blades are arranged in a staggered, parallel pattern with opposite spiral directions, creating a three-dimensional tumbling mixing effect during rotation. This effectively eliminates material stratification and ensures thorough integration of particles and liquid components. The scraper's bottom remains in contact with the bottom surface of the mixing tank, simultaneously scraping away any residual filling, avoiding mixing deviations and hygiene hazards caused by residues in traditional equipment.

[0012] Furthermore, the discharge port at the bottom of the mixing tank is equipped with a flush-mounted butterfly valve, eliminating the need for manual cleaning of residues during discharge. The valve closes directly, enabling rapid discharge, reducing material waste, and improving production efficiency. The optimized layout of the top inlet, liquid inlet, and vent optimizes the operating process, supporting convenient addition and pressure balancing of multi-component materials, further enhancing the equipment's practicality and safety. The overall structure is compact, consuming less energy than traditional mixing devices, combining efficient mixing with energy-saving advantages. Attached Figure Description

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1-4 As shown, a filling mixing device for pie production is disclosed. The filling mixing device for pie production involved in this utility model mainly consists of a mixing box 1, a mixing motor 2, and a double spiral mixing mechanism 3.

[0019] The mixing tank 1 is cylindrical in shape with a flat bottom. A discharge port 11 is located at the bottom, and a butterfly valve 4 is installed at the discharge port 11. The valve plate of the butterfly valve 4 is flush with the bottom of the mixing tank 1, minimizing material residue during discharge. The top of the mixing tank 1 has a feeding port 12, a liquid injection port 13, and a vent 14. The feeding port 12 is used to add solid raw materials required for fillings, the liquid injection port 13 is used to add liquid components, such as seasoning sauces, and the vent 14 helps balance the air pressure inside the tank during mixing.

[0020] The stirring motor 2 is installed in a suitable position in the mixing tank 1, and its output shaft is fixedly connected to the top of the stirring shaft 33 to provide power for the double helix stirring mechanism 3.

[0021] The double-helix stirring mechanism 3 is located inside the mixing tank 1 and includes a first helical stirring blade 31, a second helical stirring blade 32, a stirring shaft 33, a connecting rod 34, and a scraper 35. The first helical stirring blade 31 and the second helical stirring blade 32 are arranged alternately and parallel to each other, with opposite helical directions and the same pitch. Their upper and lower ends are connected by the scraper 35, and they are connected at the same position in the middle by the connecting rod 34, forming an integral stirring structure. The bottom of the scraper 35 is completely in contact with the bottom of the mixing tank 1, and the bottom end of the stirring shaft 33 is rotatably connected to the bottom of the mixing tank 1 through a bearing, ensuring that the stirring mechanism can rotate stably inside the mixing tank 1.

[0022] When using this filling mixing device, first add the solid materials needed to make the pie filling into the mixing tank 1 through the feeding port 12, and then add the corresponding liquid materials through the liquid injection port 13. Start the mixing motor 2, which drives the mixing shaft 33 to rotate, thereby starting the double helix mixing mechanism 3 to work.

[0023] Because the first spiral mixing blade 31 and the second spiral mixing blade 32 have opposite spiral directions, they cause the filling to tumble and roll during rotation. This three-dimensional mixing method can fully mix the various components in the filling, avoiding the material stratification problem in traditional mixing methods and ensuring the uniformity of the filling.

[0024] Meanwhile, as the mixing mechanism rotates, the scraper 35 slides along the bottom of the mixing tank 1. Because the bottom of the scraper 35 is completely in contact with the bottom of the mixing tank 1, it can promptly scrape off any remaining filling at the bottom of the mixing tank 1, preventing the filling from accumulating at the bottom, ensuring consistent mixing of each batch of filling, and reducing the risk of bacterial growth.

[0025] After the filling is mixed, open the butterfly valve 4 at the discharge port 11. Since the valve plate is flush with the bottom of the mixing chamber 1, the filling can be smoothly discharged from the discharge port 11 without the need for manual cleaning of residual materials, thus improving discharge efficiency and reducing material waste. During the mixing process, the exhaust port 14 can balance the air pressure inside the chamber, ensuring the safety and stability of the mixing process.

[0026] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
