Description

Technical Field

[0001] This utility model relates to a food emulsification stability testing device, belonging to the technical field of food testing equipment. Background Technology

[0002] Food emulsification is a crucial technology in the food industry, as products such as sauces, dairy products, and beverages require maintaining an emulsified state. Food emulsification stability testing is primarily used to assess the physical stability and shelf-life performance of food emulsion systems (such as sauces, dairy products, beverages, and plant-based alternatives). Centrifugation is a commonly used method for testing food emulsification stability, simulating long-term storage and observing stratification. However, existing centrifugal emulsification stability testing equipment has weak data acquisition capabilities, relies on manual measurement of stratification volume or sedimentation amount, suffers from significant subjective errors, and cannot monitor the dynamic stratification process in real time. This invention proposes an intelligent centrifuge device with optical real-time monitoring and active noise reduction, significantly improving testing efficiency and accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a high-precision, multi-functional food emulsification stability testing device, which solves the problems of data acquisition lag and high noise and vibration of traditional centrifuges, and meets the refined needs of food research and development and quality control.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a food emulsification stability testing device, including a base, on which is provided an outer shell with an internal cavity and an opening on the upper side. The upper end of the outer shell is provided with a sealed flip cover, which can be manually opened and closed. When closed, the flip cover forms a sealed space with the outer shell. A rotating support part is provided at the bottom of the inner cavity of the outer shell. A rotor part that can rotate along the rotating support part is provided above the rotating support part. The rotating support part is used to support the rotor part, mainly bearing the weight pressure of the rotor part, and allowing the rotor part to rotate freely. One end of a rotating shaft is connected to the bottom of the rotor part. The other end of the rotating shaft passes through the bottom of the outer shell and is connected to a drive part. The drive part is embedded in the base. The drive part can drive the rotor part to rotate through the rotating shaft, which is used for power transmission.

[0005] The rotor has an inclined centrifuge chamber on its upper surface. A light-transmitting test tube is inserted into the centrifuge chamber and is used to load the mixture to be tested. The test tube is equipped with a sealing cap. The inner sidewall of the centrifuge chamber has a first mounting groove and a second mounting groove that are opened along the length of the centrifuge chamber. A light source component is installed in the first mounting groove, and a light sensor is installed in the second mounting groove. Centrifugation causes the mixture to be tested to separate into layers. The light emitted by the light source component passes through different layers of the mixture with different intensities. The light sensor can calculate the volume of the mixture layers based on the intensity of the different areas it senses, thereby capturing the dynamics of the layer interface in real time and determining its emulsification stability.

[0006] The aforementioned food emulsification stability testing device further includes a control unit, which is electrically connected to the drive unit, the light source component, and the optical sensor. The control unit is used to control the power output and to receive and analyze the electrical signals acquired by the optical sensor.

[0007] In the aforementioned food emulsification stability testing device, a conductive slip ring is provided on the side wall of the rotating shaft. The control unit is electrically connected to the stator contacts of the conductive slip ring. The light source component and the photosensitive sensor are respectively electrically connected to the rotor contacts of the conductive slip ring. The conductive slip ring rotates synchronously with the rotating shaft and the rotor, so that the light source component and the photosensitive sensor rotate synchronously with the rotor contacts of the conductive slip ring and are in a relatively stationary state to prevent wire entanglement. The control unit is electrically connected to the stator contacts of the conductive slip ring to realize the transmission of electricity and electrical signals.

[0008] In the aforementioned food emulsification stability testing equipment, a light-transmitting and sealed window is provided at the opening end of the first and second mounting tanks near the centrifuge chamber. The light-transmitting and sealed window is made of high-strength quartz glass, which ensures light transmission while maintaining its strength stability.

[0009] The aforementioned food emulsification stability testing device includes a rotating support unit comprising an annular slide rail and a connecting ring. The annular slide rail is located at the bottom of the housing. The upper end of the connecting ring is fixedly connected to the bottom of the rotor unit. The lower end of the connecting ring is inserted into the inner cavity of the annular slide rail and is provided with a levitation magnet. The bottom of the annular slide rail is provided with a fixed magnet that repels the levitation magnet. The rotating support unit mainly bears the gravity pressure of the rotor unit. The magnetic force repelling the levitation magnet and the fixed magnet forms a reaction force with the gravity of the rotor unit, reducing the pressure on the rotating shaft, saving energy consumption of the drive unit, and replacing traditional ball bearings to reduce friction and vibration.

[0010] In the aforementioned food emulsification stability testing device, a rotary bearing is provided at the contact point between the side wall of the connecting ring and the surface of the annular slide rail to prevent the connecting ring from shifting while reducing the friction between the side wall of the connecting ring and the surface of the annular slide rail.

[0011] The aforementioned food emulsification stability testing device includes adjustable legs with adjustable lengths at the four corners of the base. Each adjustable leg comprises a threaded post and a support post. The upper end of the support post has a slot, the lower end of the threaded post is inserted into the slot, and the upper end of the threaded post is fixedly connected to the bottom surface of the base. The top of the support post has a rotatable adjustment part that fits onto the outer surface of the threaded post and engages with it. Rotating the adjustment part adjusts the length of the threaded post extending out of the slot, thereby adjusting the overall support length of the adjustable legs. Furthermore, the overall levelness can be adjusted by individually adjusting the support lengths of the four adjustable legs.

[0012] In the aforementioned food emulsification stability testing device, a horizontal detection section is provided at the center of the upper surface of the rotor to facilitate adjustment of the overall levelness.

[0013] The aforementioned food emulsification stability testing device has a display and an operation panel on its base, and both the display and the operation panel are electrically connected to the control unit.

[0014] The aforementioned food emulsification stability testing device has a shell surface covered with polyurethane sound-absorbing material to form a noise reduction layer.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] (1) This utility model installs a pressure-resistant glass window on the side wall of the centrifuge chamber, and with a background light source and a light sensor, it can automatically identify the oil-water interface and sedimentation volume, and can output the stratification rate curve through calculation, and monitor in real time, which can effectively improve work efficiency and avoid manual measurement errors.

[0017] (2) This utility model uses a magnetic levitation structure to replace the traditional ball bearing for support, reducing friction and vibration. At the same time, it wraps a porous sound-absorbing layer made of polyurethane foam, reducing noise to below 55 dB. It can also reduce energy consumption, extend motor life, and reduce maintenance frequency. Attached Figure Description
