Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a high-efficiency hot air circulating freeze-drying equipment for rapid freeze-drying of fruits. Background Technology

[0002] Vacuum freeze-drying technology, which directly sublimates solid ice in materials into water vapor at low temperature and low pressure, can preserve the original color, aroma, taste, shape and nutrients of food to the greatest extent. It is widely used in the processing of high value-added foods, especially in the field of fruit drying.

[0003] Existing fruit freeze-drying equipment typically features multiple layers of support plates within a vacuum chamber for storing fruit. However, in practical use, it has been found that this storage structure has significant limitations. Most equipment uses a fixed spacing between the support plates, which is inconvenient when processing fruits of different sizes. For example, the fixed layer height may not be sufficient for processing larger fruits, while processing sliced ​​or smaller fruits results in a significant waste of vertical space. This significantly reduces the equipment's single-batch processing capacity and space utilization, leading to poor equipment versatility. While some equipment incorporates adjustable layer height structures, the adjustment and locking methods are often complex, requiring tools or cumbersome steps, making operation inconvenient and time-consuming. Furthermore, the reliability of the locking structure needs improvement, impacting production efficiency.

[0004] Therefore, this utility model proposes a high-efficiency hot air circulating freeze-drying fruit rapid freeze-drying equipment to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the high-efficiency hot air circulation freeze-drying fruit rapid freeze-drying equipment, such as fixed shelf height, inability to adapt to different sizes of fruit resulting in low space utilization, narrow applicability, and complex shelf height adjustment and locking structure, which are inconvenient to operate, this utility model aims to provide a high-efficiency hot air circulation freeze-drying fruit rapid freeze-drying equipment with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a high-efficiency hot air circulating freeze-drying fruit rapid freeze-drying device, including: a body, a freeze-drying mechanism disposed in the body, and a storage mechanism disposed in the body and including a support column and a carrier plate disposed in a vertical direction; as well as a slider, an eccentric wheel for locking the carrier plate on the support column, and a control component for adjusting the position of the carrier plate.

[0007] The control component includes a threaded tube and a threaded rod.

[0008] Furthermore, the bearing plate is slidably connected to the support column via the slider. Rotating the threaded tube can drive the threaded rod to move along its axial direction to lift or lower the adjacent bearing plate. After rotation, the eccentric wheel can press the slider to fix the bearing plate to the support column.

[0009] Preferably, the threaded rod of the control component is threaded into the interior of the threaded tube, and the top end of the threaded rod abuts against the bottom of the upper adjacent bearing plate.

[0010] Preferably, the freeze-drying mechanism includes a vacuum pump, a refrigeration compressor, a heating component, and a condensation component.

[0011] Preferably, the heating component includes a blower, a heater, and an airflow duct, wherein the outlet of the blower is connected to the inlet of the heater, and the outlet of the heater is connected to the airflow duct.

[0012] Preferably, the airflow duct is arranged around the outer wall of the housing of the machine body, and the heating component further includes an exhaust pipe communicating with the airflow duct.

[0013] Preferably, the condensation assembly includes a condensation box and a condensation plate disposed inside the condensation box.

[0014] Preferably, the condensation assembly is located at the upper part of the housing.

[0015] Preferably, the machine body is provided with a circular sealed door for loading and unloading materials.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up a storage mechanism consisting of a control component and an eccentric wheel, uses the lifting of a threaded rod to achieve precise adjustment of the position of the bearing plate, and then achieves rapid locking through the pressing action of the eccentric wheel. This solves the problems of fixed shelf height, inability to adapt to materials of different sizes, low space utilization, and complicated adjustment and locking operations in the existing freeze-drying equipment storage racks. It achieves the technical effects of freely adjusting shelf height, improving equipment versatility and space utilization, and making the locking operation more convenient and reliable. 2. This utility model indirectly heats the inside of the chamber by means of a hot air duct that circulates outside the chamber and a high-efficiency condensation component to capture water vapor. This solves the problems that may exist in the prior art, such as uneven heating leading to a decrease in freeze-drying quality and untimely removal of water vapor leading to excessively long freeze-drying time. It achieves the technical effects of uniformly heating the material inside the chamber, ensuring freeze-drying quality, shortening freeze-drying time and saving energy. 3. This utility model solves the problems of existing equipment having a single structure, low functional integration, and poor operation convenience by organically combining a flexibly adjustable storage mechanism with a high-efficiency hot air circulating freeze-drying mechanism. It achieves the technical effect of a compact and reasonable overall structure, comprehensive functions, multi-purpose use, and user-friendly operation. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figures 1 to 4 This utility model provides a high-efficiency hot air circulating freeze-drying fruit rapid freeze-drying equipment, which aims to solve the problems of low space utilization, limited applicability, and complex height adjustment and locking structure of existing freeze-drying equipment storage racks due to fixed shelf height.

[0021] like Figure 1As shown, a high-efficiency hot air circulating freeze-drying fruit rapid freeze-drying equipment includes a body 1, a freeze-drying mechanism 2 and a storage mechanism 3 set in the body 1. The body 1 serves as the support platform for the entire equipment and is equipped with a circular sealed door for loading and unloading materials. The freeze-drying mechanism 2 is used to freeze-dry the fruit, and the storage mechanism 3 is used to support and adjust the storage position of the fruit.

[0022] Please refer to the following carefully. Figure 3 and Figure 4 The structure of the storage mechanism 3 is described in detail below. The storage mechanism 3 includes a support column 301, a slider 302, a bearing plate 303, an eccentric wheel 304, and a control component 305 arranged vertically. The bearing plate 303 is slidably connected to the support column 301 via the slider 302 and is used to support the fruit to be processed. The control component 305 is used to adjust the vertical position of the bearing plate 303. The eccentric wheel 304 is used to lock and fix the bearing plate 303 after adjustment. The control component 305 includes a threaded tube 3051 and a threaded engagement screw. The threaded rod 3052 inside the threaded tube 3051 can be driven to move up and down along its axis by rotating the threaded tube 3051. The top of the threaded rod 3052 abuts against the bottom of the upper adjacent support plate 303, thereby achieving precise adjustment of the position of the support plate 303. After adjustment, the eccentric wheel 304 can be rotated to press the slider 302, thereby fixing the support plate 303 firmly on the support column 301 through friction. This adjustment and locking structure ensures convenient operation and high stability after fixing.

[0023] Based on the above embodiments, please refer to Figure 2 The freeze-drying mechanism 2 further includes a vacuum pump 201, a refrigeration compressor 202, a heating component 203, and a condensing component 204. The heating component 203 includes a blower 2031, a heater 2032, and an airflow duct 2033. The outlet of the blower 2031 is fixedly connected to the inlet of the heater 2032, and the outlet of the heater 2032 is fixedly connected to the airflow duct 2033. The airflow duct 2033 is arranged around the outer wall of the chamber of the machine body 1. The heating component 203 also includes an exhaust pipe 2034 that communicates with the airflow duct 2033. The condensing component 204 is arranged on the upper part of the chamber of the machine body 1, and includes a condenser box 2041 and a condenser plate 2042 arranged inside the condenser box 2041.

[0024] Working principle: The freeze-drying unit 2 is designed to achieve rapid and efficient freeze-drying while preserving the quality of the fruit. First, the fruit to be processed is placed in the freeze-drying unit 1, and the circular sealed door of the unit 1 is closed. At this time, the refrigeration compressor 202 is started to rapidly reduce the temperature inside the chamber of the unit 1. After freezing, the vacuum pump 201 is started to rapidly reduce the atmospheric pressure inside the unit 1, meeting the vacuum conditions required for the direct sublimation of ice. At this time, the heating component 203 is started, and the blower 2031 pumps ambient air into the heater 2032. The air is heated here and enters the airflow duct 2033, flowing around the chamber of the unit 1, thereby raising the temperature inside the chamber and providing heat for the sublimation of ice in the vacuum. The air is then discharged through the exhaust pipe 2034. The water vapor produced by sublimation moves upward and enters the condensation component 204. The condensation box 2041 is equipped with a condensation plate 2042, which cools the water vapor and directly condenses it into frost, preventing moisture from lingering inside the chamber, shortening the freeze-drying time, and saving energy. The function of the storage mechanism 3 is to adjust the height of each storage space inside the body 1. The support plate 303 is the part for holding fruit, and the support column 301 is the supporting component. The support plate 303 slides up and down on the support column 301. The spacing between different support plates 303 can be controlled by the operation control component 305 to adapt to the size of different kinds of fruit. Rotating the threaded tube 3051 causes the threaded rod 3052 to move up and down along the thread, lifting or lowering the adjacent support plate 303 to achieve the adjustment purpose. After the adjustment is completed, the eccentric wheel 304 is turned so that it uses the eccentric structure to press the slider 302 and the support plate 303 onto the support column 301.
