Description

Technical Field

[0001] The present invention relates to the technical field of vegetable drying, and particularly relates to a vegetable air separation drying system and method. Background Art

[0002] Dried vegetables, also known as dehydrated vegetables, are a kind of dried vegetables made after removing most of the water in vegetables. This processing method is not only easy to store and transport, but also can effectively adjust the output of vegetables in the off-season and peak season of production. When eating, just immerse them in clear water to restore them, and retain the original color, nutrition and flavor of the vegetables.

[0003] The existing vegetable drying process makes its production line longer, and during use, in order to prevent the vegetables from getting burnt, low-temperature long-time drying is adopted, resulting in low drying efficiency. After drying is completed, it is impossible to ensure the drying degree of all vegetables, which may lead to vegetables with higher moisture content inside. Thus, mildew will occur after packaging.

The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be construed as a limitation on the protection scope of the present invention.

[0018] Referring to Figure 1-8 , an embodiment of a vegetable air separation and drying system of the present invention includes: a tank body 1, the inner surface of the tank body 1 is rotatably connected with a drying barrel 2, and the rotation mode of the drying barrel 2 is the same as that of an existing washing machine, that is, it rotates several circles, stops, rotates in the reverse direction for several circles, and so on repeatedly. The side surface of the tank body 1 is fixedly connected with a power motor 14, the output end of the power motor 14 is fixedly connected with a power gear 15, the side surface of the drying barrel 2 is fixedly connected with a gear ring 16, the power gear 15 is meshed with the gear ring 16, a track 17 is arranged at the contact position between the drying barrel 2 and the tank body 1, the inner surface of the drying barrel 2 is fixedly connected with an electric heating wire 3, a plurality of drying cavities 4 are arranged inside the drying barrel 2, a plurality of inclined downward filter screens 5 are arranged inside the drying cavities 4, and the filter screens 5 are arranged in a staggered manner. The inclination angle of the filter screens 5 gradually decreases from top to bottom, and a vibration motor 6 is arranged on the side surface of the drying barrel 2.

[0019] Specifically, the vegetable raw materials are added into the drying chamber 4. The power motor 14 drives the power gear 15 to rotate, driving the gear ring 16 to rotate. The gear ring 16 drives the drying barrel 2 to rotate, causing the materials to adhere to the inner wall of the drying chamber 4 under the action of centrifugal force for drying. Then it stops, and the raw materials fall along the inclined filter screen. It rotates in the reverse direction again to flip the raw materials to avoid damage. At the same time, during the drying process, under the action of the vibration motor 6, the raw materials vibrate to facilitate falling.

[0020] Inside the tank body 1, there is a hot air selection ring 7. The side surface of the hot air selection ring 7 is fixedly connected with an arc-shaped baffle 8. Inside the tank body 1 and above the hot air selection ring 7, there is an arc-shaped discharge plate 9. The bottom end of the arc-shaped discharge plate 9 is lower than the highest point of the arc-shaped baffle 8. The arc on the arc-shaped discharge plate 9 is opposite to the arc on the arc-shaped baffle 8. Inside the hot air selection ring 7, there is a hot air outlet 10.

[0021] Specifically, the vegetables fall onto the hot air selection ring 7. Due to the wind force from the hot air outlet 10, the wind drives the vegetables to rush towards the arc-shaped baffle 8. The dried vegetable raw materials, being light in weight, rush up along the arc-shaped baffle 8 onto the arc-shaped discharge plate 9 and fall into the mixing chamber 11. The materials with heavier mass do not have enough speed and thus fall into the hot air selection ring 7, are dried by the hot air, and after reaching the drying degree, fall into the mixing chamber 11.

The side surface of the mounting shaft 18 is rotatably connected with a feed hopper 21. The feed hopper 21 includes a connecting column 22 which is rotatably connected with the mounting shaft 18. One end of the connecting column 22 far from the mounting shaft 18 is fixedly connected with a hopper body 23. The lower surface of the hopper body 23 is fixedly connected with a distributing pipe 24, and the number of the distributing pipes 24 is the same as the number of the drying chambers 4.

[0025] Specifically, the screen 19 closes the inlet to prevent the centrifugal force from throwing the materials out and can discharge the moisture. The closing cover 20 increases the internal pressure for rapid discharging. The feed hopper 21 facilitates the simultaneous addition of corresponding materials. The materials enter the hopper body 23 and then enter the drying chambers 4 through the distributing pipes 24.

Feeding: The vegetable raw materials enter the drying chambers 4 through the feed hopper 21, and the internal electric heating wires 3 are started. The drying chambers 4 are preheated for 5 - 10 minutes before the vegetable raw materials enter. S2. Drying: During the drying process, the hot air from the lower hot air outlet 10 and the heating of the electric heating wires 3 together dry the incoming vegetable raw materials. At the same time, the movement mode of the drying barrel 2 is the same as that of a washing machine in the prior art. When it stops rotating, through the vibration effect of the vibration motor 6, the vegetable raw materials are dropped from the filter screen 5. S3. Winnowing: The dried vegetables fall onto the surface of the hot air winnowing ring 7. Through the hot air blown out from the hot air outlet 10, the vegetables dried to a certain extent are blown up, reach the arc-shaped discharge plate 9 along the arc-shaped baffle 8, and then fall into the mixing chamber 11. S4. Mixing: When multiple kinds of vegetables need to be mixed, the stirring blades 12 inside the mixing chamber 11 rotate to stir and mix the vegetables. S5. Discharging: During discharging, the raw materials are discharged through the discharge pipe 13. The drying barrel 2 is sealed by the sealing cover 20, and hot air enters through the hot air outlet 10 to increase the internal pressure, so as to quickly discharge the raw materials from the discharge pipe 13.
