Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a clean air outlet pipe used for a food drying machine. Background Art

[0002] The food industry is an important industry related to people's livelihood, including various primary and fine processing of food. Drying is a more common processing procedure. Different foods need to go through the corresponding dryer to complete this process. Take the common beverage shops on the market as an example. Among the various beverages, tea bags are generally needed. The tea bags contain tea products made from picked tea after multiple processing steps, including the drying process. During this process, the tea leaves are spread flat on the baking tray, and the baking trays are placed layer by layer inside the dryer. Hot air is introduced into the dryer through the pipe and then discharged. Through the flow of hot air and the increase in the temperature inside the dryer caused by it, the tea leaves are spread flat on the baking tray, and the baking trays are placed layer by layer inside the dryer. Hot air is introduced into the dryer through the pipe and then discharged. Through the flow of hot air and the increase in the temperature inside the dryer caused by it, the tea leaves are dried. For drying tea leaves, the traditional air outlet duct has a simple structure, generally with only one basic pipe body, the lower opening is exposed to collect the return hot air, and the upper opening is connected to the matching fan. However, the return hot air will inevitably carry impurities such as broken tea leaves inside the baking tray and fine dust on the surface of the tea leaves, and introduce these impurities into the fan. If manpower is not invested in corresponding cleaning, it will affect the long-term stable operation of the fan. Based on this situation, how to smoothly guide the return hot air while avoiding impurities such as broken tea leaves and fine dust from entering the fan as much as possible, so that the fan can operate stably for a long time, is becoming an increasingly urgent problem that relevant technical personnel need to solve. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a clean air outlet duct for a food dryer.

The staff only needs to remove the collector to clean the impurities, which effectively reduces the manpower required for cleaning work;

[0011] 3. The lower connector and the lower sealing gasket effectively ensure the stability of the connection between the air outlet duct and the corresponding connection position of the dryer. The upper connector and the upper sealing gasket effectively ensure the stability of the connection between the air outlet duct and the end of the fan exhaust duct, thereby effectively ensuring the stability of the operation of the air outlet duct. The threaded connection between the middle threaded part and the pipe body provides a good structural foundation for the staff to flexibly adjust the position of the lower connector to adapt to different installation conditions, effectively ensuring the applicability of the air outlet duct;

[0012] 4. The air cooler, horizontal pipe and inclined pipe tilted upward provide a good structural basis for the tilted upward introduction of cold air, ensuring rapid cooling of the return hot air while effectively avoiding the risk of overheating of the air outlet duct and the supporting fan, thereby effectively ensuring the safety of the air outlet duct.

DETAILED DESCRIPTION

[0023] In order to make the description clearer, a clean air outlet duct for a food dryer of the utility model is further described in conjunction with the accompanying drawings of the specification.

[0024] A clean air outlet duct for a food dryer comprises a tube body 5, characterized in that: a ventilation hole 9 is penetrated at the lower part of the tube body 5, a slide rail 15 is vertically arranged at the inner upper part of the tube body 5, a filter screen 17 is horizontally arranged inside the tube body 5, sliders 18 are symmetrically fixed on both sides of the filter screen 17, the sliders 18 are slidably connected to the slide rails 15, a collector 3 is arranged below the tube body 5, a lower threaded portion 16 is arranged at the inner upper part of the collector 3, and the lower threaded portion 16 is threadedly connected to the tube body 5.

[0025] Furthermore, an upper connector 1 is provided on the upper part of the tube body 5, an upper threaded portion 12 is provided on the inner side of the upper connector 1, the upper threaded portion 12 is threadedly connected to the tube body 5, an upper sealing gasket 7 is fixedly provided on the upper part of the upper connector 1, and upper connecting holes 11 are equidistantly annularly penetrated inside the upper connector 1 and the upper sealing gasket 7.

[0026] Furthermore, a lower connector 2 is arranged in the middle of the tube body 5, a middle threaded portion 14 is arranged on the inner side of the lower connector 2, the middle threaded portion 14 is threadedly connected to the tube body 5, a lower sealing gasket 4 is fixedly arranged on the upper part of the lower connector 2, and lower connecting holes 13 are equidistantly arranged in an annular shape inside the lower connector 2 and the lower sealing gasket 4.

[0027] Furthermore, air coolers 6 are symmetrically fixedly arranged on both sides of the upper part of the tube body 5, a horizontal tube 8 is fixedly arranged on one side of the air cooler 6 close to the tube body 5, the horizontal tube 8 extends to the inside of the tube body 5, an inclined tube 10 is fixedly arranged on one end of the horizontal tube 8 away from the air cooler 6, the inclined tube 10 is inclined upward, the inclined tube 10 and the horizontal tube 8 are an integral structure, and the upper end of the horizontal tube 8 is flush with the upper end of the slide rail 15.

[0028] The working principle of a clean air outlet duct for a food dryer of the utility model is as follows: according to the specific installation situation, after comprehensively considering the sizes of the upper and lower parts of the tube body 5 that need to be exposed, the lower connector 2 is screwed until it moves to a suitable position, the upper surface of the lower sealing gasket 4 is fitted with the lower surface of the installation position, the matching bolts are screwed into the lower connecting hole 13 until the upper surface of the lower sealing gasket 4 is tightly fitted with the lower surface of the installation position, the upper connector 1 is tightened to the upper end of the tube body 5, the end of the exhaust duct of the matching fan is fitted with the upper surface of the upper sealing gasket 7, the matching bolts are screwed into the upper connecting hole 11 until the end of the exhaust duct is tightly fitted with the upper surface of the upper sealing gasket 7, and the installation work of the air outlet duct is completed. After the hot air is introduced into the dryer through the air inlet pipe, the drying process begins, the fan is started, and the hot air that has blown through the baking tray is blown out through the air inlet pipe. The internal channel of the dryer flows to the air outlet duct and enters the tube body 5 through the ventilation hole 9. The hot air moves upward inside the tube body 5, blowing the filter 17 and the slider 18 as a whole to move upward along the slide rail 15 to the lower part of the horizontal tube 8. The broken tea leaves, tiny dust and other impurities entrained in the hot air are adsorbed on the lower surface of the filter 17. The filtered hot air passes through the filter 17, and the air cooler 6 is started. The air cooler 6 blows cold air in the direction of the horizontal tube 8. The inclined tube 10 makes the cold air tilt upward and is introduced into the tube body 5. The cold air quickly cools the filtered hot air and is guided to the designated position by the fan. After the drying process is completed, the filter 17 moves vertically downward to the bottom of the slide rail 15 under the action of gravity. The instantaneous collision between the slider 18 and the bottom of the slide rail 15 causes the impurities filtered out by the filter 17 to fall into the collector 3. The staff only needs to unscrew the collector 3 to clean the impurities inside.

[0029] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
