Description

Technical Field

[0001] This utility model relates to the field of nozzle structure technology, specifically to an anti-sticking nozzle structure for spray drying and powdering of mushroom extracts. Background Technology

[0002] In the spray drying process of mushroom extract, the extracted and purified active ingredients are first formulated into a liquid slurry of suitable viscosity and then conveyed to the nozzle via a conveying system. Inside the nozzle, the slurry is atomized into micron-sized droplets under pressure or centrifugal force. After entering the drying tower, the droplets come into full contact with the high-temperature hot airflow, causing rapid evaporation of moisture and ultimately forming a dry, powdery product, completing the liquid-to-solid transformation.

[0003] Current nozzle structures are mostly traditional designs, which have significant shortcomings when processing mushroom extract slurries: relying solely on pressure or centrifugal force for atomization results in poor crushing of high-viscosity materials, uneven droplet distribution, and viscous components easily sticking to the nozzle, leading to raw material waste and frequent cleaning. To address this, we propose an anti-sticking nozzle structure for spray drying and powdering mushroom extracts. Utility Model Content

[0004] The purpose of this invention is to provide an anti-sticking nozzle structure for spray drying and powdering of mushroom extracts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-sticking nozzle structure for spray drying and powdering mushroom extract, comprising a support frame and a drying tower snapped into the inner end of the support frame. A support plate is fixedly connected to the upper end of the outer wall of the drying tower, and a water pump is fixedly connected to the top of the support plate. An inlet pipe extending through and into the upper end of the drying tower is fixedly connected to the output end of the water pump. A nozzle is provided at the output end of the inlet pipe. An air pump is installed on the top of the support plate near the inlet pipe. An air inlet pipe extending through and into the inlet pipe is fixedly connected to the output end of the air pump. A gas distribution pipe is embedded in the wall of the air inlet pipe, and a gas distribution valve is provided on the wall of the gas distribution pipe. A locking sleeve connected to the inner wall of the drying tower is fitted around the outer ends of the inlet pipe and the nozzle. A jetting mechanism connected to the gas distribution pipe is provided on one side of the locking sleeve. The jetting mechanism includes several jet nozzles arranged in the inner ring.

[0006] Preferably, the support frame is fixedly connected to four legs at its bottom corners.

[0007] Preferably, a main valve is installed on the air pump input pipe.

[0008] Preferably, a plurality of the jet nozzles are arranged in an inward tilt, and a notch is provided at the bottom end of the inner ring of the jet mechanism.

[0009] Preferably, both the air intake pipe and the air distribution pipe are unidirectional channels.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the gas output from the air pump is divided into two paths, and the velocity difference between the slurry in the air inlet pipe and the liquid inlet pipe generates strong shearing force, which efficiently breaks up the high viscosity mushroom slurry and improves the atomization fineness; the air distribution pipe forms an annular air curtain through the inward-curving jet nozzle, which not only prevents droplets from sticking to the wall in reverse, but also washes away nozzle residue, resulting in a prominent dual anti-sticking effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides the following technical solution:

[0018] Example 1: Anti-sticking nozzle structure for spray drying of mushroom extract powder, including support frame 1 and drying tower 2 snapped into the inner end of support frame 1, with support legs 11 fixedly connected to the four corners of the bottom end of support frame 1.

[0019] When in use, the drying tower 2 is accurately snapped into the inner end of the support frame 1. The four corner legs 11 at the bottom of the support frame 1 are used to firmly support the overall structure, ensuring that the drying tower 2 remains stable during the subsequent spray drying process, and providing a stable equipment installation foundation for the spray drying and powdering process of mushroom extract.

[0020] Example 2: The technical solution of this example, which differs from Example 1, includes: a support plate 21 fixedly connected to the upper end of the outer wall of the drying tower 2; a water pump 22 fixedly connected to the top of the support plate 21; an inlet pipe 23 extending through and into the upper end of the drying tower 2 fixedly connected to the output end of the water pump 22; a nozzle 24 provided at the output end of the inlet pipe 23; an air pump 3 installed on the top of the support plate 21 near the inlet pipe 23; an air inlet pipe 31 extending through and into the inlet pipe 23 fixedly connected to the output end of the air pump 3; a gas distribution pipe 4 embedded in the wall of the air inlet pipe 31; a gas distribution valve 41 provided on the wall of the gas distribution pipe 4; and the outer ends of the inlet pipe 23 and the nozzle 24... A locking sleeve 42 is fitted onto the inner wall of the drying tower 2. A jetting mechanism 43 connected to the gas distribution pipe 4 is provided on one side of the locking sleeve 42. The jetting mechanism 43 includes several jet nozzles 44 arranged in the inner ring. A main valve 32 is installed on the input pipe of the air pump 3. The several jet nozzles 44 are arranged in an inward tilt, and a notch is opened at the bottom of the inner ring of the jetting mechanism 43. Both the air inlet pipe 31 and the gas distribution pipe 4 are one-way channels. The one-way channels can prevent gas or liquid backflow. The locking sleeve 42 secures the liquid inlet pipe 23 and the nozzle 24 to ensure the stability of the overall process. The notch at the bottom of the inner ring of the jetting mechanism 43 can prevent the accumulation of slipped liquid.

[0021] In use, the water pump 22 is started, and the liquid slurry of mushroom extract is delivered to the nozzle 24 through the liquid inlet pipe 23. At the same time, the air pump 3 is turned on, and the air intake is adjusted by the main valve 32. The gas is divided into two paths: one path enters the liquid inlet pipe 23 directly through the air inlet pipe 31, forming a high-speed speed difference with the slurry flowing at low speed in the pipe, generating strong shearing force and initially breaking the slurry into liquid filaments; the other path is delivered to the jet mechanism 43 through the air distribution pipe 4 (the air volume is adjusted by the distribution valve 41). The inwardly inclined jet nozzle 44 of the inner ring sprays out clean airflow, forming an annular air curtain around the nozzle outlet. This not only wraps the atomized droplets to prevent them from sticking to the nozzle surface due to turbulence, but also acts like an "air scraper" to wash away residual material at the outlet. The residual material will slide off from the notch of the jet mechanism 43. Combined with the fine atomization achieved by the shearing force, it greatly reduces the adhesion to the wall.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
