Description

Pastry emulsifier mixing device Technical Field

[0001] This utility model relates to a pastry emulsifier mixing device. Background Technology

[0002] In the pastry production process, emulsifiers are often added to batters or emulsions to improve the taste, extend shelf life, and enhance structural stability. The dispersion and mixing quality of emulsifiers directly affects their uniform distribution and effectiveness in the final product. However, existing emulsifier mixing equipment typically suffers from problems such as insufficient mixing, inaccurate temperature control, numerous dead zones in the mixing process, and inconvenient cleaning, especially when handling high-viscosity materials or complex formulations. Furthermore, most current equipment lacks multi-stage mixing and efficient dispersion capabilities, making it difficult to meet the high requirements of modern pastry production for the fineness and stability of emulsifier dispersion.

[0003] Therefore, there is an urgent need for a pastry emulsifier mixing device with high temperature control accuracy, strong mixing efficiency, good emulsification effect, and easy cleaning and maintenance to solve the problems existing in the current technology. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a convenient pastry emulsifier mixing device.

[0005] A pastry emulsifier mixing device includes a mixing chamber, a multi-stage stirring system, and a cleaning system. The mixing chamber comprises a double-layered stainless steel shell with a temperature-controlled interlayer between the inner and outer layers. The temperature-controlled interlayer includes a spiral coil, which is welded to the double-layered stainless steel shell. The inlet and outlet of the spiral coil are connected to a cooling water circulation device or a heat transfer oil circulation device. The inner layer of the double-layered stainless steel shell is made of SUS316 stainless steel, and its inner surface is polished. The multi-stage stirring system includes a main stirring mechanism, a high-speed dispersing disc, and an ultrasonic auxiliary device. The main stirring mechanism includes a stirring rod, a first drive motor, rotating blades, and a wall scraper. The high-speed dispersing disc is located at the bottom of the mixing chamber and includes multiple stacked serrated discs and a second drive motor. Viewed from top to bottom, the main stirring mechanism rotates clockwise while the high-speed dispersing disc rotates counterclockwise. The spiral coil structure expands the heat exchange area, and with the circulation of cooling water / heat transfer oil, the temperature regulation is more uniform, adapting to the temperature sensitivity of emulsifiers; the SUS316 food-grade material and polished inner wall reduce material residue and bacterial growth; the main agitator and dispersion disc rotate in opposite directions, forming convection shear, combined with ultrasonic refining dispersion, solving the mixing dead zone problem of traditional equipment; cooling water cooling or heat transfer oil heating can be switched to adapt to different emulsifiers.

[0006] As a further improvement, the cooling water circulation device includes a water storage tank, circulation pipelines, and a water pump. It quickly removes heat through circulating water, making it suitable for emulsifiers that require low-temperature mixing and reducing energy consumption.

[0007] As a further improvement, the heat transfer oil circulation device includes an oil storage tank, which is equipped with an electric heater. The oil storage tank is connected to the spiral coil through a circulation oil circuit and an oil pump. The electric heater works with the heat transfer oil to achieve stable high-temperature control and avoid local overheating.

[0008] As a further improvement, the rotating blades include several arc-shaped blades. One end of each arc-shaped blade is connected to the stirring rod and arranged in a circular array around the axis of the stirring rod. The wall scraper is connected to the other end of the arc-shaped blades. The wall scraper is a flexible scraper, the shape of which matches the curvature of the inner wall of the cavity. The scraper and the arc-shaped blades are connected by a detachable structure. The scraper fits against the cavity wall, avoiding hard friction damage to the inner wall, while adapting to changes in material viscosity. The detachable design facilitates the replacement of worn scrapers, reducing maintenance costs. The arc-shaped blades guide the axial flow of materials, improving circulation efficiency.

[0009] As a further improvement, the detachable structure of the scraper and the arc-shaped plate is a bolt connection structure or a plate and slot connection structure, which allows the scraper to be replaced without special tools, shortens downtime, and adapts to different cleaning needs.

[0010] As a further improvement, the serrated disk is a disk with evenly distributed acute-angled teeth on its edges, with an acute angle of 30° to 60°. The acute-angled teeth enhance local turbulence, breaking the emulsifier particles into finer particles and reducing the risk of clumping.

[0011] Beneficial effects:

[0012] 1. High-efficiency emulsification and uniform mixing: A multi-stage stirring system is adopted, including a main stirring mechanism, a high-speed dispersing disc and an ultrasonic auxiliary device, to form multi-directional and multi-level composite stirring, so as to achieve full dispersion of emulsifier and improve mixing uniformity and emulsification efficiency.

[0013] 2. Precise temperature control system: The double-layer stainless steel shell structure is designed with an internal spiral coil. Combined with a cooling water or heat transfer oil circulation device, the mixing environment temperature can be flexibly adjusted according to process requirements to ensure that the emulsifier works stably under suitable temperature conditions.

[0014] 3. Excellent corrosion resistance and cleaning performance: The inner layer of the mixing chamber is made of SUS316 stainless steel and the inner surface is polished, which effectively avoids material adhesion and residue, facilitates cleaning, and meets the safety requirements of food production.

[0015] 4. Prevent material accumulation and sticking to the wall: The main mixing mechanism is equipped with a flexible wall scraper, which can continuously scrape and mix closely to the inner wall of the cavity, avoiding dead corners and material accumulation.

[0016] 5. Easy to maintain and replace: The scraper adopts a detachable structure, such as bolt connection or insert slot structure, which is easy to disassemble and replace, reducing maintenance difficulty and cost.

[0017] 6. Enhanced dispersion effect: The high-speed dispersion disc adopts a multi-layer sawtooth disc structure with stacked upper and lower layers and is set to rotate in the opposite direction. In combination with the main agitator, it effectively improves the shear force and refining effect of the emulsifier. Attached Figure Description

[0029] The overall workflow of the device is as follows:

[0030] 1. Preparation stage:

[0031] Select the temperature control mode based on the type of emulsifier, hydrophilic / lipophilic:

[0032] Hydrophilic emulsifiers, such as lecithin, can activate cooling water circulation to lower the temperature to 25°C–40°C.

[0033] Lipophilic emulsifiers, such as monoglycerides, are used to start the heat transfer oil heating process, raising the temperature to 60℃–80℃.

[0034] Add the aqueous or oil phase raw material into the mixing chamber 1.

[0035] 2. Mixing stage:

[0036] Main stirring mechanism 9 starts:

[0037] It rotates clockwise at a low speed of 20–60 rpm, and the arc-shaped blades push the material to circulate axially.

[0038] The flexible scraper simultaneously removes deposits from the inner wall to prevent coking.

[0039] High-speed distributed disk 10 startup:

[0040] The high-speed counterclockwise rotation at a speed of 500–3000 rpm applies shearing force to the material, breaking up emulsifier particles.

[0041] The main stirring mechanism 9 and the high-speed dispersing disc 10 rotate in opposite directions to create convection and enhance the mixing effect.

[0042] Ultrasonic assisted start:

[0043] High-frequency vibration, with a frequency of 20–40 kHz, further refines the emulsifier dispersion, forming a stable emulsion.

[0044] The sensor monitors viscosity and temperature in real time and automatically stops when the target is met.
