Description

Technical Field

[0001] This utility model belongs to the technical field of a special dietary ultra-low temperature cell wall breaking and pulverizing device, and provides a special dietary ultra-low temperature cell wall breaking and pulverizing device that extends service life, is easy to apply to different ingredients, and improves cell wall breaking and pulverizing efficiency. Background Technology

[0002] See the herbal medicine cell wall breaking pulverizer published in Chinese Patent 201610676329.9. Its structure includes a base, motor, grinding cylinder, grinding rods, refrigeration device, exciter, vibration spring, rotating shaft and eccentric block. The grinding cylinder is located in the aforementioned soundproof box. The outer circumference of the grinding cylinder is wrapped with a cooling coil and the inner wall is smooth. The grinding cylinder has an axial hollow channel in the middle. Both ends of the hollow channel are provided with bearings. The grinding cylinder has a port, and a collection cylinder is provided on the port that can be opened and closed. Multiple grinding rods are placed in the aforementioned grinding cylinder, and the surface of each grinding rod is smooth. During use, the aforementioned herbal cell wall breaking and pulverizing machine uses a vibrating spring connected to the machine base. The vibrating spring is prone to fatigue (traditional vibrating springs are prone to plastic deformation under high-frequency impact, resulting in a decrease in amplitude stability and fluctuations >20%) and low energy transfer efficiency (energy loss of over 40%), which leads to attenuation of the grinding cylinder amplitude and low cell wall breaking and pulverizing efficiency over time. The vibrating spring has a short service life, requiring frequent shutdowns to replace it, resulting in high maintenance costs. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a special ultra-low temperature cell wall breaking and pulverizing device for food that extends service life, is easy to apply to different ingredients, and improves cell wall breaking and pulverizing efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a special ultra-low temperature cell wall breaking and pulverizing device for dietary use, including a base, a motor and a grinding cylinder located on the base. The grinding cylinder has an axial hollow channel in the middle, and a rotating shaft is provided in the hollow channel. A bearing is provided between the rotating shaft and the grinding cylinder. The rotating shaft is connected to the output shaft of the motor through a coupling. A funnel-shaped feed inlet is provided on the grinding cylinder, and a closable collection cylinder is provided at the feed inlet. Multiple grinding rods are placed in the inner cavity of the grinding cylinder, and each grinding rod has a smooth surface. Vibrating elements are provided on both sides of the grinding cylinder. Two support columns are symmetrically arranged on both sides of the lower end of the vibrating element. Vibration springs are provided on the support columns. An integral flange is provided in the middle of the lower end of the vibrating element. An eccentric block is provided on the rotating shaft and rotates with it. The eccentric block drives the vibrating element to move up and down at the support columns.

[0006] Wherein: a hydraulic damper is installed in the vibration spring, and a connecting seat a and a connecting seat b are fixed at the top and bottom ends of the hydraulic damper, respectively. The top and bottom ends of the vibration spring abut against the bottom plate surface of the connecting seat a and the bottom plate surface of the connecting seat b, respectively. The connecting seat a is fixed to the lower end of the exciter, and the connecting seat b is fixed to the top end of the support column.

[0007] To facilitate the installation and removal of the hydraulic damper, the above scheme further includes: both connecting seat a and connecting seat b are flanges, and threaded holes are provided on both connecting seat a and connecting seat b.

[0008] To reduce vibration, the above solution further includes: the hydraulic chamber of the hydraulic damper is connected to an external pipe, one end of which is fixedly connected to an external hose, and the other end of which passes through a clearance hole and connects to a constant pressure hydraulic tank. The clearance hole is located on the connecting seat b, and the constant pressure hydraulic tank is fixed on the machine base.

[0009] To be applicable to different ingredients, the above solution further includes: the hydraulic damper is an adjustable damper with adjustable damping magnitude.

[0010] To achieve low-temperature cell wall breaking and pulverization, the above scheme further includes: the grinding cylinder has two independent inner cavities, the outer inner cavity is a cooling cavity, the grinding rod is located in the inner inner cavity, and the grinding cylinder is provided with a cooling medium inlet pipe and a cooling medium outlet pipe that communicate with the cooling cavity.

[0011] The beneficial effects of this utility model are:

[0012] Due to the aforementioned structure, the vibration spring first dampens the vibration of the exciter, ensuring stable vibration of the grinding cylinder by the two exciters. When the vibration spring undergoes plastic deformation over time, causing an abnormal increase in amplitude, the hydraulic damper increases the damping. Under normal operating conditions, the damping force of the hydraulic damper is maintained at a minimum value to avoid additional energy loss. Through the dynamic compensation of the hydraulic damper, a balance between amplitude stability and energy loss is achieved, effectively ensuring the operating time of the entire device, avoiding frequent shutdowns to replace the vibration spring, and extending its service life. The amplitude is stable during operation, improving the cell wall crushing efficiency. The hydraulic damper is an adjustable damper, suitable for different ingredients, effectively ensuring the required stable amplitude according to the needs of different ingredients.
