Description

Technical Field

[0001] The utility model belongs to the technical field of food additive processing, and particularly relates to a drying device for food additives. Background Art

[0002] Food additives are artificial or natural substances added to food to improve its color, aroma, taste and other qualities, as well as for preservation and processing needs. Food additives have greatly promoted the development of the food industry and are known as the soul of the modern food industry. This is mainly because they bring many benefits to the food industry, such as preventing spoilage and facilitating processing.

[0003] During the production and processing of food additives, they need to be dried by a drying device. However, when the existing drying device is used, the food additives are heated unevenly, resulting in a long drying time, so that the drying efficiency of the food additives needs to be improved.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to provide a drying device for food additives, which can solve the problem of low drying efficiency of food additives caused by uneven heating of food additives.

[0009] The drying assembly includes a stirring shaft rotatably mounted within a housing. A crushing impeller and a stirring impeller are mounted on the sidewalls of the stirring shaft. Rotation of the stirring shaft drives the crushing impeller and stirring impeller to rotate. The rotation of the crushing impeller crushes food additives agglomerated on the screening plate and simultaneously increases the efficiency of the screening plate in screening the food additives. The rotation of the stirring impeller stirs the screened food additives, thereby ensuring uniform heating of the food additives during drying and improving drying efficiency. A conveying trough is defined within the stirring shaft, through which hot air is conveyed within the stirring shaft. Both the crushing impeller and the stirring impeller are defined with a flow channel, the flow channel communicating with the flow channel, allowing hot air conveyed through the flow channel to be conveyed into the flow channel. Multiple first nozzles are mounted at the bottom of each of the crushing impeller and the stirring impeller. A second nozzle is mounted on the end of each of the crushing impeller and the stirring impeller away from the stirring shaft, allowing hot air within the flow channel to be ejected through the first and second nozzles, thereby drying the food additives.

[0010] The hot air ejected from the first nozzle at the bottom of the crushing impeller heats the food additives while increasing their efficiency in screening on the screening plate. The hot air ejected from the first nozzle at the bottom of the stirring impeller evenly contacts the food additives while the stirring impeller stirs them, thereby evenly heating the food additives and improving drying efficiency. As food additives dry in the housing, they adhere to the inner wall of the housing. To clean these adhered food additives, a second nozzle is provided so that the hot air ejected from the second nozzle can purge them.

[0011] In one or more embodiments of the present invention, a feed pipe is installed on the top wall panel of the shell, a discharge pipe is installed on the bottom wall panel of the shell, and a switch valve is installed on the discharge pipe.

[0016] In one or more embodiments of the present invention, the stirring shaft is placed on the side wall outside the top wall panel of the shell and is equipped with a connecting ring, and the outer wall of the connecting ring is rotatably connected to a rotating ring, so that the connecting ring and the rotating ring can rotate relative to each other, thereby facilitating the supply of hot air to the stirring shaft through the action of the connecting ring and the rotating ring.

[0017] In one or more embodiments of the present invention, the stirring shaft is provided with a plurality of first air inlet holes on the side wall outside the top wall panel of the shell, and the connecting ring is provided with a plurality of second air inlet holes matching the first air inlet holes, so that hot air can enter the stirring shaft through the second air inlet holes and the first air inlet holes.

[0018] In one or more embodiments of the present invention, an air inlet is provided on the rotating ring, and an air pipe is installed at the air inlet on the outer wall of the rotating ring. The hot air is transported to the second air inlet through the rotating ring through the air pipe, and the second air inlet transports the hot air to the stirring shaft through the first air inlet, so that the hot air flows in the conveying trough.

[0031] like Figures 1 to 3 As shown, the drying device body 1 includes a housing 11, within which the food additives to be dried are dried. A sieve plate 12 is mounted within the housing 11. Since food additives tend to clump, the sieve plate 12 facilitates screening of the agglomerated material. The sieve plate 12 is provided with a plurality of sieve holes 13, allowing the material to flow through the sieve holes 13 to the bottom of the sieve plate 12.

[0032] like Figures 1 to 3 As shown, a feed pipe 14 is installed on the top wall of the shell 11 , a discharge pipe 15 is installed on the bottom wall of the shell 11 , and a switch valve 16 is installed on the discharge pipe 15 .

[0033] like Figure 2 and Figure 3 As shown, the drying component 2 includes a stirring shaft 21, which is installed in the shell 11 in a rotatable manner. A crushing impeller 22 and a stirring impeller 23 are installed on the side wall of the stirring shaft 21, so that the rotation of the stirring shaft 21 can drive the crushing impeller 22 and the stirring impeller 23 to rotate. The rotation of the crushing impeller 22 can crush the food additives agglomerated on the screening plate 12, and at the same time accelerate the efficiency of the screening plate 12 in screening food additives; the rotation of the stirring impeller 23 can stir the screened food additives, so that the food additives are heated evenly during drying, thereby improving the drying efficiency.

[0034] Furthermore, a conveying trough 24 is provided in the stirring shaft 21, through which hot air can be conveyed into the stirring shaft 21. A circulation trough 25 is provided in both the crushing impeller 22 and the stirring impeller 23, and the conveying trough 24 and the circulation trough 25 are connected, so that the hot air conveyed through the conveying trough 24 can be conveyed into the circulation trough 25. A plurality of first nozzles 26 are installed at the bottom of each of the crushing impeller 22 and the stirring impeller 23, and a second nozzle 27 is installed at the end of each of the crushing impeller 22 and the stirring impeller 23 away from the stirring shaft 21, so that the hot air in the circulation trough 25 can be ejected through the first nozzle 26 and the second nozzle 27, so that the hot air can dry the food additives.

[0035] Preferably, the hot air ejected from the first nozzle 26 at the bottom of the crushing impeller 22 can improve the efficiency of food additive screening on the screening plate 12 while heating the food additive. The hot air ejected from the first nozzle 26 at the bottom of the stirring impeller 23 can evenly contact the food additive while the stirring impeller 23 stirs the food additive, thereby evenly heating the food additive and improving the drying efficiency. When the food additives are drying in the housing 11, the food additives will adhere to the inner wall of the housing 11. In order to clean the attached food additives, a second nozzle 27 is provided so that the hot air ejected from the second nozzle 27 can clean the attached food additives by blowing.
