Description

Technical Field

[0001] This application relates to the field of food processing, and in particular to an energy-efficient onion grinder. Background Technology

[0002] Onions, a widely used ingredient in catering and food processing, require crushing as a common process in food production. The crushing effect directly impacts the quality of subsequent processed products, such as the smoothness of onion sauce and the uniformity of seasonings. Currently, existing energy-efficient onion grinders typically crush onions solely through mechanical structures (such as blade cutting and roller pressing), with the degree of crushing primarily controlled by the magnitude and frequency of mechanical force.

[0003] However, existing onion crushing technology has obvious limitations: the cell structure of onions is quite special, and the cell walls are prone to incomplete crushing and large differences in particle size during mechanical crushing due to uneven force. Especially for onions with high water content, mechanical crushing may also cause juice splashing and loss of effective components, further affecting the crushing quality. At the same time, the crushing environment (such as air pressure conditions) of traditional crushers is fixed and cannot be adapted to the characteristics of onions (such as freshness, water content, variety) and different crushing requirements (such as coarse crushing and fine crushing), resulting in insufficient stability and flexibility of crushing effect.

[0004] In actual production, the air pressure of the crushing environment is one of the key factors affecting the crushing effect of onions. When the crushing environment is under different air pressure conditions, the pressure difference inside and outside the onion cells will change: under high pressure, the onion cells are compressed, the cell walls are subjected to concentrated force, and it is easier to achieve uniform crushing under mechanical action; under low pressure, the splashing of juice during cell rupture can be reduced, and the loss of effective components can be reduced. Existing technologies have not recognized the significant impact of air pressure on the crushing effect of onions, nor have they proposed technical solutions to optimize the crushing effect by adjusting the crushing environment pressure. As a result, existing energy-saving onion grinders are unable to meet the high requirements of crushing quality, efficiency and product quality in food production. Therefore, there is an urgent need for an onion crushing technology that can improve the crushing effect by adjusting the crushing environment pressure, in order to solve the problems of incomplete crushing, uneven particle size, serious juice loss, and difficulty in flexibly adjusting the crushing effect in existing technologies, so as to improve the quality and efficiency of onion crushing and processing and meet the diverse needs of food production.

[0023] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This application discloses an energy-saving onion grinder, including: a cylinder 10, a sealing cover 14, a negative pressure module, a temperature module, and a signal processing module; specifically, the cylinder 10, as the main support structure of the equipment, is made of food-grade stainless steel, which has the characteristics of corrosion resistance, easy cleaning, and high strength, and can avoid chemical reaction between the onion and the cylinder 10 during the crushing process, thus avoiding affecting the quality; the external contour is preferably constructed in a cylindrical shape, with a cylinder wall and a cylindrical crushing chamber 11 defined by the cylinder wall; the inner diameter is set according to the crushing capacity, which can meet the batch processing needs of small and medium-sized food processing scenarios; A crusher 30 is installed inside the crushing chamber 11. The crusher 30 adopts a rotary crushing structure, including a drive motor 31, a crushing shaft 32, and a set of crushing blades 33. The drive motor 31 is fixed to the outside of the top of the cylinder 10, and its output shaft passes through the cylinder wall and is connected to the crushing shaft 32 for transmission. The crushing shaft 32 is arranged along the central axis of the crushing chamber 11. The set of crushing blades 33 is evenly distributed along the axial direction of the crushing shaft 32. Each set of crushing blades 33 includes an arc-shaped crushing blade. The blade is blunted to avoid excessive cutting that would cause the onion cells to break too quickly and produce a large amount of irritating gas, while ensuring the uniformity of the crushed onion particles. Specifically, the sealing cover 14 is made of food-grade silicone and a stainless steel frame, possessing good sealing performance and structural stability. The sealing cover 14 is fixedly installed on the inner wall of the crushing chamber 11, completely enclosing the crusher 30 to form a sealed chamber for onion crushing, effectively preventing the diffusion of irritating gases generated during the crushing process. The sealing cover 14 is along a first direction, which is along... Figure 5 The straight line shown; a feed pipe 12 and a discharge pipe 13 are respectively provided. The feed pipe 12 is located at the top of the sealing cover 14 and communicates with the sealing cavity, and is used to transport the onions to be crushed into the sealing cavity; the discharge pipe 13 is located at the bottom of the sealing cover 14 and communicates with the sealing cavity, and is used to discharge the crushed onion fragments. Both the feed pipe 12 and the discharge pipe 13 are made of stainless steel and are sealed to the sealing cover 14 by a sealing ring to ensure the sealing of the sealing cavity; More specifically, the negative pressure module is used to regulate the air pressure inside the sealed cavity. By controlling the negative pressure environment inside the sealed cavity, the diffusion of irritating gases during the onion crushing process is suppressed, while also assisting in the settling and discharge of the onion fragments. In this application, the air pressure inside the sealed cavity is changed to achieve diversified effects in onion crushing. For example, crushing onions under vacuum conditions has the characteristics of inhibiting capsaicin diffusion, preventing browning, preserving color, and eliminating bubbles; crushing onions under high pressure conditions has the characteristics of ultra-fine particles, deactivating enzymes, cold sterilization, and long-lasting freshness; crushing onions under low pressure conditions has the characteristics of loose and non-sticky texture, easy drying at low temperature, and flavor retention. Therefore, different crushing environments are selected according to the onion application environment. In this application, the negative pressure module includes a pressure sensor and a negative pressure unit; wherein, the pressure sensor is a high-precision diffused silicon pressure sensor, which is fixedly installed on the inner wall of the sealing cover 14 and communicates with the sealing cavity, for real-time detection of pressure changes in the internal space of the sealing cavity, and converts the detected pressure signal into a first detection signal (electrical signal) and transmits it to the signal processing module; the measurement of the pressure sensor can accurately capture the air pressure fluctuations in the sealing cavity so as to facilitate subsequent precise control of the pressure in the sealing cavity; The negative pressure compressor uses a small oil-free negative pressure pump, which is connected to the sealed cavity through an air guide pipe. A solenoid valve is installed on the air guide pipe to control its opening and closing. The negative pressure compressor can pressurize and depressurize the sealed cavity to meet the air pressure requirements of different crushing stages. The installation methods of the negative pressure compressor described above are all existing technologies, therefore they are not detailed in the accompanying drawings of this application. The connection layout can be designed according to actual usage. The negative pressure compressor is electrically connected to the signal processing module and executes corresponding air pressure adjustment operations in response to the first input command sent by the signal processing module. The pressure sensor is signal-connected to the signal processing module. After receiving the first detection signal, the signal processing module can select a working mode according to a preset program, or convert the first detection signal into a corresponding first input command based on the current working mode. The working modes include automatic and manual modes. In automatic mode, the signal processing module automatically adjusts the working state of the negative pressure compressor according to the preset target pressure value to maintain the air pressure in the sealed cavity within the target range. In manual mode, the operator can input commands to the signal processing module through an external control panel to control the operation of the negative pressure compressor. The first input command includes at least the following: preset target output pressure, data viewing, data storage, and locking or blocking the first detection signal. The preset target output pressure can be set according to the onion variety and crushing requirements; the data viewing command can retrieve historical pressure data detected by the pressure sensor; the data storage command can store real-time pressure data to the storage unit of the signal processing module for easy subsequent traceability; the locking command can fix the current pressure value, allowing the negative pressure machine to maintain its current working state; the blocking command can temporarily block the detection signal of the pressure sensor and switch to manual control mode.

[0025] The above-mentioned solution allows operators to select different crushing environments based on the subsequent application of crushed onions, thus improving the versatility of crushing methods.

[0026] In this application, the temperature module is used to regulate the temperature inside the sealed cavity, preventing the onion's temperature from rising due to frictional heat during the crushing process, which would damage the onion's nutritional components and texture. Specifically, when the crushing environment is between 0℃ and 10℃, it can inhibit capsaicin production, prevent browning, maintain crispness, and extend freshness; when the crushing environment is between 80℃ and 90℃, it completely inactivates enzymes, facilitates fine processing, improves storage life, and reduces viscosity. The temperature module includes a temperature sensor and a temperature control device, and its specific structure and working principle are as follows: The temperature sensor is a platinum resistance temperature sensor, fixedly installed on the inner wall of the sealing cover 14, close to the crusher 30. It is used to monitor the temperature changes inside the sealed cavity in real time and convert the detected temperature signal into a second detection signal (electrical signal) which is then transmitted to the signal processing module. The temperature sensor can accurately monitor temperature fluctuations inside the sealed cavity.

[0027] The temperature control device includes a cooling component and a heating component. The cooling component uses a semiconductor cooling chip, fixed to the outer wall of the sealing cover 14, and communicates with the sealing cavity through a heat-conducting plate to achieve rapid cooling. The heating component uses a heating wire embedded in the inner wall of the sealing cover 14 to heat the sealing cavity in a low-temperature environment and maintain a suitable crushing temperature. The temperature control device is electrically connected to the signal processing module and executes the corresponding temperature control operation in response to the second input command sent by the signal processing module.

[0028] The temperature sensor is connected to the signal processing module. After receiving the second detection signal, the signal processing module can select an operating mode according to a preset program, or convert the second detection signal into a corresponding second input command based on the current operating mode. The operating modes also include automatic and manual modes. In automatic mode, the signal processing module automatically switches between the cooling and heating components based on a preset target temperature value to maintain the temperature within the sealed cavity within the target range. In manual mode, the operator can control the temperature regulation device via an external control panel. The second input command includes at least: preset target output temperature, data viewing, data storage, and locking or blocking the second detection signal. Its functions are consistent with the corresponding functions of the first input command, respectively realizing temperature parameter preset, data traceability, data storage, temperature locking, and manual switching functions.

[0029] The signal processing module uses a PLC controller, which is fixed on the outer wall of the cylinder 10. It has the functions of signal reception, processing, storage and command transmission. The signal processing module is connected to the pressure sensor and negative pressure machine of the negative pressure module, the temperature sensor and temperature adjustment device of the temperature module, the electromagnet 48 of the feeding mechanism, and the second electromagnet 48 of the adjustment plate 50, etc., to realize the coordinated control of each component. Based on the above scheme, during the operation, the combination of low temperature + vacuum or high temperature blanching + low pressure can achieve the superimposed effect: Low temperature + vacuum crushing: double inhibition of capsaicin and browning, the freshness, color and crispness of onions are best preserved, which is the core process of high-end fresh-cut onions; High temperature blanching + low pressure crushing: after enzyme inactivation, the low pressure makes the onion structure more loose, further improving the dehydration efficiency and flavor retention, which is suitable for processing high-quality dehydrated onion powder. More specifically, a feeding mechanism is installed on the inner wall of the feed pipe to precisely adjust the feeding speed and amount of onions, avoiding excessive feeding at one time and causing excessive load on the crusher 30. At the same time, it works in conjunction with the negative pressure environment of the sealing chamber to prevent gas leakage during the feeding process. The feeding mechanism includes a sealing plate 41, a movable plate 42, and a drive assembly. Specifically, the sealing plate 41 is a circular plate structure that fits the inner diameter of the feed pipe 12. The sealing plate 41 is fixed in the middle of the inner wall of the feed pipe 12. The sealing plate 41 has an arc-shaped concave part, and an opening connecting to the sealing chamber is opened in the middle of the arc-shaped concave part. The opening is a circular hole structure, and its size is set according to the particle size of the onions, allowing one or more onions to pass through in an orderly manner. Two movable plates 42 are provided on the surface away from the concave arc. The total width of the two movable plates 42 is greater than the width of the opening. The opening can be opened, closed, and the opening range can be adjusted by relative sliding. The surface of the movable plates 42 is adapted to the contour of the surface of the sealing plate 41, and the two movable plates 42 can move relative to each other. To improve sliding stability, the surface of the sealing plate 41 is provided with a sliding groove that matches the movable plates 42. The movable plates 42 are embedded in the sliding groove and slide back and forth along the sliding groove to avoid displacement during sliding.

[0030] In this embodiment, an airbag is provided on the surface of the sealing plate 41 that contacts the onion (i.e. the surface facing the top of the feed pipe 12). The airbag is made of food-grade elastic rubber, which is laid in line with the surface of the sealing plate 41 and covers the area around the opening. The airbag can undergo elastic deformation when the onion comes into contact with it, avoiding damage caused by hard contact between the onion and the sealing plate 41, while further improving the sealing performance. A through hole is formed on the surface of the sealing plate 41, which is cylindrical in shape. A piston block 45 is slidably mounted on the inner wall of the through hole. The piston block 45 is made of stainless steel and its length is greater than the depth of the through hole. Part of the piston block 45 protrudes from the surface of the sealing plate 41 away from the airbag (i.e., the side facing the sealing cavity). A first elastic element 46 is provided between the piston block 45 and the inner wall of the through hole. The first elastic element 46 is a compression spring, one end of which is fixed to the bottom of the through hole and the other end is connected to the piston block 45. It provides an elastic force to the piston block 45 in the direction of the sealing cavity, so that the part of the piston block 45 protruding from the surface of the sealing plate 41 is always in contact with the movable plate 42. When the movable plate 42 slides, the piston block 45 moves with the movable plate 42 under the action of the first elastic element 46, always maintaining the contact state, while squeezing the airbag to make it fit against the bottom of the movable plate 42, thereby improving the sealing effect.

[0031] The driving assembly, used to drive the two movable plates 42 to slide relative to each other, includes a permanent magnet 47, an electromagnet 48, and a second elastic element 49. The permanent magnet 47 is fixedly disposed at the end of each movable plate 42, with opposite polarities on the two movable plates 42. The electromagnet 48 is disposed opposite to the permanent magnet 47 at the end of the sliding groove of the sealing plate 41. The electromagnet 48 is fixed to the sealing plate 41 by a bracket and electrically connected to the signal processing module. The polarity of the generated magnetic field can be adjusted by changing the direction of the current. The second elastic element 49 is a tension spring, with its two ends connected to the opposite ends of the two movable plates 42, providing an elastic force that brings the two movable plates 42 closer together, keeping the movable plates 42 closed when there is no electromagnetic driving force, thus closing the opening.

[0032] When feeding material, the signal processing module sends a control signal to the electromagnet 48 to adjust the direction of the current in the electromagnet 48, so that the electromagnet 48 generates a magnetic field that repels the permanent magnet block 47. The repulsive force overcomes the pulling force of the second elastic element 49, driving the two movable plates 42 to move away from each other and opening the opening. The opening width can be controlled by adjusting the current of the electromagnet 48. The larger the current, the greater the repulsive force, the larger the opening width, and the faster the feeding speed. When feeding stops, the signal processing module cuts off the current of the electromagnet 48, the magnetic field disappears, and the two movable plates 42 move closer to each other under the pulling force of the second elastic element 49, closing the opening and completing the seal.

[0033] In a more specific embodiment, an adjusting plate 50 is movably installed inside the discharge pipe 13 to adjust the internal volume of the sealed cavity and control the discharge timing and speed. A guide groove 51 is formed on the inner wall of the discharge pipe 13 along a first direction (vertical direction). The guide groove 51 is rectangular. Slider blocks 52, adapted to the guide groove 51, are formed on both sides of the adjusting plate 50. The sliders 52 are embedded in the guide groove 51, allowing the adjusting plate 50 to reciprocate along the guide groove 51, moving away from or closer to the crusher 30 along the first direction, thereby adjusting the internal size of the sealed cavity to meet different crushing requirements.

[0034] A magnetically conductive block 53, made of ferromagnetic material, is mounted on the slider 52 and fixed to the side of the slider 52 away from the adjusting plate 50. A second electromagnet 48 is positioned on the outer wall of the discharge pipe 13, opposite to the magnetically conductive block 53. The second electromagnet 48 is fixed to the outer wall of the discharge pipe 13 by a bracket and electrically connected to the signal processing module. The magnetic field strength and polarity can be adjusted by changing the direction and magnitude of the current. The magnetic field generated by the second electromagnet 48 attracts or repels the magnetically conductive block 53, driving the slider 52 to move along the guide groove 51, thereby moving the adjusting plate 50 and achieving precise control of the position of the adjusting plate 50. To improve positioning stability, multiple second electromagnets 48 are provided, evenly distributed along the length of the guide groove 51. The second electromagnet 48 at the corresponding position can be activated according to the target position of the adjusting plate 50, achieving multi-point positioning of the adjusting plate 50.

[0035] The regulating plate 50 is also equipped with a feeding mechanism that has the same structure as the feeding mechanism inside the feed pipe 12, which is used to control the unloading of the crushed onion fragments. After crushing is completed, the signal processing module controls the feeding mechanism on the regulating plate 50 to open, and at the same time adjusts the position of the regulating plate 50 so that the crushed onion fragments are discharged along the discharge pipe 13. After unloading is completed, the feeding mechanism is controlled to close to ensure the sealing of the sealing cavity and facilitate the next crushing operation.
