Description

Technical Field

[0001] This application relates to the technical field of coffee bean freezing, and specifically relates to a freeze-drying device. Background Art

[0002] Coffee beans refer to the plant fruits used to make coffee. Generally speaking, there are two types of coffee beans in the world, Arabica beans and Robusta beans. The fruit of coffee is composed of two oval seeds facing each other. The side where they are connected is a flat joint surface, called flat beans. However, there are also those composed of a single round seed, called round beans, and their taste is the same;

[0003] Freeze-drying of coffee beans is a processing method that removes the moisture in coffee beans through freezing and vacuum drying. This method can effectively retain the flavor and aroma of coffee beans and extend their shelf life at the same time.

[0004] For example, the patent with the publication number CN215951972U specifically discloses a water removal device for a vacuum freeze-dryer, including the settings of a dryer, a water removal mechanism, an air inlet hole, a box body, a mounting plate, an adsorption plate and a suction fan, so as to absorb moisture, and then discharge the converted gas through a filter screen, achieving the effect of water removal and improving work efficiency.

[0005] When the above-mentioned patent freeze-dryer is in use, by placing coffee beans on a tray and then putting them into the vacuum freeze-dryer, when freeze-drying some foods, the food will adhere to the bottom of the tray. When taking out the food later, it is easy to make the food difficult to separate from the tray, resulting in the food adhering to the tray. At the same time, for the residual materials adhering to the corners and gaps of the tray, it may be difficult to clean thoroughly, easily causing cross-contamination in subsequent freeze-drying. Therefore, it is necessary to design a freeze-drying device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0023] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0024] As Figures 1 - 3 shown, this application provides a freeze-drying device, including a freeze dryer 1, on which a cover door 101 is hinged. The cover door 101 is used to seal the freeze dryer 1. Inside the freeze dryer 1, multiple groups of trays 102 are installed. The tray 102 has a material storage area 103 for storing coffee beans, and multiple groups of through holes (not marked in the figure) are provided on the tray 102, which are suitable for freeze-drying the upper and lower surfaces of the coffee beans;

[0025] The tray 102 has two working areas 104, and an anti-adhesion component 2 is installed in the working area 104. The anti-adhesion component 2 includes a concave plate 201 fixedly installed in the working area 104. A motor 202 is fixedly installed on the side of the concave plate 201. The output end of the motor 202 is fixedly installed with a lead screw 203. A lead screw sleeve 204 is threadedly connected to the lead screw 203. The lead screw 203 is adapted to rotate with the output end of the motor 202 to enable the lead screw sleeve 204 to move along the linear direction of the lead screw 203;

[0026] A fixed box 205 is fixedly installed on the lead screw sleeve 204. A chute 206 is provided on the side surface of the fixed box 205. A slider 207 is slidably installed in the chute 206. A circular rod 209 is connected between two groups of sliders 207. And the slider 207 has a protruding rod, which movably penetrates through the fixed box 205. And a spring 208 is sleeved on the protruding rod. One end of the spring 208 is fixedly connected to a top end of the inner wall of the chute 206. The other end of the spring 208 is fixedly connected to the upper surface of the slider 207;

[0027] The spring 208 is adapted to restrict the slider 207 so as to press the slider 207 against the bottom end of the inner wall of the chute 206;

[0028] A fixed sleeve 210 is movably sleeved on the circular rod 209. A scraper 211 is fixedly installed on the upper surface of the fixed sleeve 210. A harrow nail (not shown in the figure) is fixedly installed on the lower surface of the fixed sleeve 210. The fixed sleeve 210 is adapted to move synchronously with the movement of the lead screw sleeve 204 so as to tumble the coffee beans stored in the storage area 103 to avoid sticking to each other or sticking to the tray 102;

[0029] A fixed pin 212 is inserted into the fixed sleeve 210. The fixed pin 212 penetrates through the fixed sleeve 210 and is inserted into the circular rod 209 so as to direct the harrow nail towards the tray 102;

[0030] A housing 213 is fixedly installed on the tray 102 and in the working area 104 at the same time. The housing 213 is used to protect the anti-adhesion assembly 2. At the same time, an opening groove adapted to the fixed box 205 is provided on the housing 213;

[0031] Working principle:

[0032] After placing the coffee beans to be dried in the storage area 103 on the tray 102, closing the cover door 101, and simultaneously turning on the freeze dryer 1 and the motor 202, the motor 202 drives the lead screw 203 to rotate, so that the lead screw sleeve 204 linearly moves on the lead screw 203 and drives the fixed sleeve 210 to move, so as to drive the harrow nail to tumble the coffee beans stored in the storage area 103 to avoid sticking to each other or sticking to the tray 102;

[0033] After drying is completed and the freeze dryer 1 is not in use, by pulling out the fixing pin 212, then pulling up the circular rod 209 to compress the spring 208, and then rotating the fixing sleeve 210 by 180 degrees. After the scraper 211 on the fixing sleeve 210 faces the storage area 103, fix it by inserting the fixing pin 212, and then loosen the upward pulling of the circular rod 209. Under the action of the spring 208, the circular rod 209 is reset. At this time, the scraper 211 contacts the storage area 103. Starting the motor 202 again will drive the fixing sleeve 210 to move, so as to be suitable for removing the residual materials adhering to the corners and gaps of the storage area 103.

[0034] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
