An air-drying device for melon with a rotating air gun

technical field

The invention relates to the technical field of melon production, in particular to an air-drying device for melon with a rotating air gun.

Background technique

Gualou is the dried and mature fruit of Cucurbitaceae or bilateral cucurbita, and the fruit, seed coat and seeds of Gualou can be used as medicine. The whole dried fruit is called whole melon, the shell is called melon rind, and the seeds are called melon seeds. Gualou has the functions of clearing away heat and phlegm, widening the chest and dispelling knots, moisturizing dryness and smoothing the intestines. It is one of the widely used Chinese herbal medicines. Polysaccharides are the most abundant components in Gualou, up to 39%. Studies have shown that guarana polysaccharides have antioxidant and cardioprotective activities. The content of polysaccharide is an indicator of the sweetness of melon, which has important reference significance for the edible value of melon. Flavonoids are one of the effective components of Fructus Fructus, and rutin and quercetin have obvious crown-expanding effects. Studies have shown that the total flavonoids of Fructus Fructus have obvious protective effects on the vascular endothelium. The total flavonoids of Gualou is also one of the index components of Gualou Xiebai granules. Gualou saponin is the main medicinal component of Gulou, which has the functions of calming the heart and calming the nerves, nourishing qi and dredging the pulse, anti-tumor, promoting body fluid and quenching thirst, and immune regulation.

Among them, in the production of melon, the peel of melon has the most medicinal value. It is necessary to cut the melon to take out the seeds of melon, and then process the peel. The drying of the peel is very important. A production process, in the prior art, when drying the rind of melon, all the rind is placed on the carrier plate, and then the plate is placed in an oven for long-term drying work, which is not only low in efficiency, but also in drying. In the process of drying, there is only hot air from the lower part, so for many melons on the carrier plate, the drying efficiency and drying uniformity are low, and it is impossible to achieve uniform drying of all melons, which greatly reduces the drying process of melons. It is extremely inconvenient to affect the overall production efficiency of melon rind.

The present invention at least has the following beneficial effects:

In the present invention, when the melon with a rotating air gun is used with an air-drying device, first place the desired dried melon rind in the bearing cylinder, start the fan, the driving motor and the electric heating device, and use the driving motor to drive the rotating rod to rotate , and then can drive the rotating air duct to rotate, and at the same time use the fan to extract the hot air from the electric heating equipment, pressurize the air booster pump, and then send it to all the air gun tubes through the rotary joint and the rotating air duct, and pass through all the air gun tubes. The air gun barrel rotates and blows the peel of the melon, and when the hot air output from the other outlet of the air booster pump passes through the bottom frame, it will drive the spiral blades to rotate through the action of high-pressure wind, thereby making the air passing through the spiral blades rotate. The wind presents a whirlwind effect, and then cooperates with all the rotating air gun barrels to blow the melon rind, so that the melon rind is always almost suspended and hot, and with the rotation of the air gun barrel, the melon rind can be blown up. Rotate, and make the contact between the rind and the hot air more extensive. Compared with the prior art, when drying the rind, the rind is placed on the carrier plate, and then the plate is placed in the oven for drying. Long-term drying work is not only inefficient, but also only has hot air from the lower part during the drying process. Therefore, for many melons on the carrier plate, the drying efficiency and drying uniformity are low, and it is impossible to achieve all the melons. For the problem of uniform drying, in the method of the present invention, the wind can be in a cyclone state through the air intake of the bottom frame and the spiral blades, and at the same time, the high-pressure air outlet of all the air gun barrels and the rotation of the air gun barrel can make the melon. The rind is blown up and appears in a suspended state, which greatly enhances the drying effect on the rind and the uniformity of drying.

The present invention also has the following beneficial effects:

1. The stirring blades on all the air gun barrels can not only rotate with the air gun barrels, but also rotate under the action of the wind force in the bearing cylinder, thereby driving the stirring blades to rotate. When the stirring blades are in contact with the melon peel When the rind is dried to the mobile level, the rind will be preliminarily broken, because it needs to be broken when the rind is used in the later stage, so that the rind can be preliminarily broken by the stirring blade, which is convenient for later use. .

2. The use of the top filter plate and the bearing filter plate can avoid the debris of the melon rind in the drying process, which will be carried out with the wind, thereby avoiding the loss of the melon rind raw material and enhancing the processing accuracy. While rotating the air duct, it can drive the scraper and brush to rub and clean the bottom of the top filter plate and the bottom of the bearing filter plate, so as to prevent the top filter plate and the bearing filter plate from being blocked by melon debris, which will affect the box body. Works with the air outlet of the carrying cylinder.

3. When it is necessary to discharge the crushed materials in the bearing cylinder, there are still unbroken melon rinds at this time. It is very inconvenient to directly open the bearing cylinder and take it out. At this time, the first discharge plate in the two side frames can be It can be docked with the discharge chute on the second discharge plate, and then the second discharge plate can be fixed, and the discharge chute after the docking can be used to discharge the material, and the size of the butt joint of the two discharge chute can be controlled at the same time. Furthermore, the size of the overall discharge port can be changed, so that the crushed size of the melon rind can be controlled for discharge, and then the melon rind that has not reached the crushed size can be continuously crushed.
