Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shiitake mushroom processing technology, specifically a shiitake mushroom dehydration device with uniform heating. Background Technology
[0002] Shiitake mushrooms are a common edible fungus. Their caps are thick and umbrella-shaped, with a dark brown or light brown surface and white flesh. They are rich in nutrients such as polysaccharides and amino acids, and have a fresh and fragrant taste. They can be eaten fresh or processed. Dehydration is an important way to preserve shiitake mushrooms. By removing water, the growth of microorganisms is inhibited, the shelf life is extended, and nutrients and flavor are preserved. Dehydrated shiitake mushrooms are easier to store and transport, and their freshness can be restored after soaking.
[0003] According to a search, patent document CN219228971U discloses a mushroom dehydration device, including a housing. This mushroom dehydration device, through the coordinated arrangement of a feeding pipe, a first motor, a first transmission rod, a first rotating rod, and a squeezing roller, allows mushrooms to be poured into the feeding pipe. The first motor then drives the squeezing roller to squeeze out the water from the mushrooms, thus assisting in dehydration and improving dehydration efficiency. Through the coordinated arrangement of a second motor, a second transmission rod, a second rotating rod, a stirring blade, a mounting frame, and a drying cylinder, the second motor drives the second rotating rod and stirring blade to rotate, causing the stirring blade to uniformly stir the mushrooms in the drying cylinder, ensuring even heating. Through the coordinated arrangement of a heating chamber, an air inlet, a fan plate, a blower, and an electric heating element, the blower blows heated air into the drying cylinder, thus drying and dehydrating the mushrooms.
[0004] The aforementioned comparative document also has the following shortcomings: The bottom of the drying drum in the aforementioned comparative document is equipped with an inclined discharge pipe. When the shiitake mushrooms are stirred, some of the shiitake mushrooms may fall into the discharge pipe. These shiitake mushrooms are not fully stirred, resulting in uneven heating and affecting the overall quality. At the same time, the aforementioned comparative document is equipped with a pair of extrusion rollers to squeeze out the moisture in the shiitake mushrooms. The extrusion rollers may damage the shiitake mushrooms during the extrusion process, thus ruining the product appearance. In addition, the squeezed water may drip into the drying drum.

Specifically, the support assembly is used to support and stabilize the cylinder 2. The baffle 22 on the feed port 21 is slid off. The shiitake mushrooms are added to the breathable mesh 3 inside the cylinder 2 through the feed port 21 and the opening on the cylinder 2. The servo motor 4 is started. The output end of the servo motor 4 drives the stirring shaft 5 to rotate forward. The one-way bearing does not transmit power to the cylinder 2. The stirring shaft 5 drives the stirring blade 6 and the pulley 7 to rotate at a suitable speed. The pulley 7 drives the heating assembly to deliver hot air. The stirring blade 6 stirs the shiitake mushrooms to achieve uniform turning of the mushrooms, avoid local accumulation, ensure consistent heating, and improve the uniformity of dehydration. After dehydration is completed, the servo motor 4 is turned off first. Then the baffle 24 on the discharge port 23 is slid off. Then the servo motor 4 is started again. The output end of the servo motor 4 drives the stirring shaft 5 to rotate 180° in reverse. The stirring shaft 5 drives the cylinder 2 to rotate together through the one-way bearing, so that the dehydrated shiitake mushrooms are poured from the opening on the cylinder 2 into the discharge port 23 for easy unloading. The support assembly includes a pair of support rods 8, both of which are fixedly connected to the corresponding side wall of the housing 1. Each support rod 8 has a bullseye wheel 9 at one end.

It consists of a high-precision ball, a base, etc. The ball of the bullseye wheel 9 contacts the cylinder 2, which can stably support the cylinder 2 without hindering the rotation of the cylinder 2. The connecting rod 10, together with the pull rod 11, enhances the structural stability of the support rod 8 and prevents deformation under stress. The heating assembly includes a cover 12, which is connected to one side of the housing 1. An installation plate 13 and an installation frame 14 are fixedly connected to the inner wall of the cover 12. A rotating shaft is rotatably connected to the installation plate 13.
