Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of resistant dextrin production, and specifically relates to a drying device for resistant dextrin production. BACKGROUND

[0002] Resistant dextrin is white to light yellow powder, which can be used as a low-calorie soluble food raw material. Resistant dextrin has the effect of resistant starch similar dietary fiber and the prevention and treatment effect on intestinal diseases, and has a broad development prospect in the food industry. In production, the dextrin solution needs to be dried by a drying device to make it dry into fine powder.

[0003] Announcement No. CN216953900U discloses "a resistant dextrin product drying bed, which comprises a main body, a first driving member arranged in the main body, a rotating disc in transmission connection with the first driving member, a connecting rod in eccentric connection with the rotating disc, a force applying rod in rotation connection with the connecting rod, a tray driven by the force applying rod, and a rotating mechanism for driving the tray to rotate. A guide pipe is arranged in the main body along the axial direction. The bottom of the tray is provided with a force receiving rod. The force receiving rod is arranged in the guide pipe from the upper side of the guide pipe. The force applying rod is arranged in the guide pipe from the lower side of the guide pipe and abuts against the force receiving rod. When the first driving member drives the force applying rod to make linear reciprocating motion, the force applying rod repeatedly lifts the tray to realize the vibration of the tray".

[0004] There are still some disadvantages in use. When continuously drying the dextrin solution, solid dextrin will continuously accumulate in the tray. The continuous increase of solid dextrin will reduce the capacity of the solution contained in the tray, which will reduce the drying speed of the subsequent solid dextrin. In addition, the rotation and up-down vibration of the tray will cause the abrasion between the gears to be intensified, which will also easily cause the gears to be stuck, resulting in the decrease of the drying rate.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0038] Please refer to Figures 1-5 In the embodiments of the utility model, a drying device for resistant dextrin production includes a drying assembly 1, the drying assembly 1 includes a drying bin 101, the drying bin 101 is internally fixedly installed with a coil pipe 105, a collecting assembly 2 is arranged on one side of the drying bin 101, a filtering assembly 3 is fixedly installed and connected between the drying assembly 1 and the collecting assembly 2, the filtering assembly 3 includes a filtering bin 301, the filtering bin 301 is internally rotatably connected with a spiral blade 305 at the lower part, the filtering bin 301 is rotatably connected with a filter cartridge 302 at the upper end of the surface at one end, and a circulating assembly 4 is arranged on one side of the drying bin 101.

[0039] Specifically, the drying bin 101 mixes dextrin solution and high-temperature gas, discharges part of the solution and the high-temperature gas into the filtering bin 301 for filtering, makes the powder enter the inside of the collecting bin 201, and makes the high-temperature gas carrying moisture enter the inside of the circulating assembly 4 for filtering.

[0040] Embodiment one

[0041] As Figure 2As shown, in this embodiment, an inlet pipe 103 is fixedly installed inside the drying chamber 101, and multiple nozzles 104 are fixedly connected to the lower end of the inlet pipe 103. An exhaust pipe 102 is fixedly installed at the upper end of the drying chamber 101 and is fixedly connected to the filter chamber 301. Multiple air holes 106 are equidistantly opened on the outer surface of the coil 105.

[0042] In this embodiment, the liquid inlet pipe 103 sprays out the external dextrin solution through the nozzle 104, and the high-temperature gas enters the coil 105 and is discharged from multiple air holes 106, so that the high-temperature gas mixes with the mist solution. The high-temperature gas dries the dextrin solution, and some powder falls downward to the bottom of the drying chamber 101. The remaining solution and gas enter the filter chamber 301 through the exhaust pipe 102.

[0043] like Figure 2 and Figure 4 As shown, in this embodiment, a scraper 307 that is movably fitted to the filter cartridge 302 is fixedly installed on the inner surface of the filter chamber 301. A first motor 303 is fixedly installed on the outer surface of the filter chamber 301. Two meshing gears 304 are fixedly installed at one end of the first motor 303 and the outer surface of the filter cartridge 302. One end of the air inlet pipe 402 is rotatably connected to the filter cartridge 302. A second motor 306 for driving the spiral blades 305 is fixedly installed on the other end surface of the filter chamber 301.

[0044] In practice, when the high-temperature gas carries some solution and powder into the filter chamber 301, it increases the contact time between the gas and the solution. The dried powder falls to the bottom of the filter chamber 301. The second motor 306 operates, driving the spiral blades 305 to rotate and pushing the powder to enter the collection chamber 201 through the feed pipe 202. This allows the dextrin powder to be discharged into the collection component 2 for collection, facilitating continuous drying of the dextrin solution, maintaining the drying speed of the subsequent dextrin solution, and improving its drying rate. The first motor 303 operates, and through the meshing transmission of two second gears 304, the filter cartridge 302 rotates. The filtered powder is scraped off by the scraper 307, and the gas and water vapor enter the air inlet pipe 402.

[0045] like Figure 2 and Figure 5As shown, in this embodiment, the collection component 2 includes: a collection chamber 201 disposed on one side of the drying chamber 101; a feed pipe 202 fixedly embedded in the upper end of the collection chamber 201 and fixedly connected to the filter chamber 301; a connecting seat 203 fixedly installed on the upper surface inside the collection chamber 201; and a baffle 204 rotatably connected to the inside of the connecting seat 203. A first gear 207 is fixedly installed at one end of the baffle 204 through the connecting seat 203. A first electric push rod 205 is fixedly installed on the upper surface inside the collection chamber 201. A rack 206 that meshes with the first gear 207 is fixedly installed at the output end of the first electric push rod 205.

[0046] In practice, the baffle 204 blocks the lower end of the feed pipe 202, blocking the falling powder. The first electric push rod 205 retracts, driving the rack 206 to move, causing it to rotate the first gear 207, which in turn drives the baffle 204 to flip, causing the powder to fall into the collection chamber 201, thereby discharging the powder from the lower end of the drying chamber 101 and the collection chamber 201.

[0047] Example 2

[0048] Based on Example 1, in order to overcome the problem that water vapor and air are not easy to collect and utilize.

[0050] In practice, high-temperature gas and water vapor enter the bottom of dehumidification chamber 401 through air inlet pipe 402 and float upward under the operation of fan 404. Water vapor is filtered by sponge 405. After the high-temperature gas loses its temperature, it is reheated by heating pipe 408 and enters the inside of connecting pipe 403. Under the traction of fan 404, it enters the inside of coil 105, thus separating water vapor and hot air for recycling, reducing the time and heat wasted in heating the outside air. The second electric push rod 407 extends, pushing the squeezing frame 406 down to squeeze sponge 405, causing the water droplets inside to fall to the bottom of dehumidification chamber 401 and be discharged to the outside.

[0051] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application.
