[0022] See Figure 1 And Figure 2The utility model discloses an embodiment of a kind of stirring parts for cold drink equipment, including shaft 1 and stirring blade 2, the shaft 1 is connected with external driving mechanism, can drive the stirring blade 2 rotation and stir solid-liquid mixture. Wherein the number of the stirring blade 2 is multiple, multiple the stirring blade 2 is connected in the lateral wall of the shaft 1. Multiple the stirring blade 2 is fixed in the lateral wall of the shaft 1 with welding or integral forming mode. The stirring blade 2 protrudes towards the radial direction of the shaft 1, multiple the stirring blade 2 is distributed along the axial direction of the shaft 1, the position of multiple the stirring blade 2 in the axial direction of the shaft 1 is staggered, arranges distribution in the way of axial non-overlapping, the side of adjacent stirring blade 2 does not link each other, since each the stirring blade 2 is arranged in the axial direction of the shaft 1 without overlapping, and the side of adjacent stirring blade 2 does not link each other, therefore the side of the stirring blade 2 is vacant portion, with the space that can flow solid-liquid mixture, the stirring blade 2 is equipped with flow space 4 in the side of the axial direction of the shaft 1, and solid-liquid mixture can flow in the flow space 4, to improve flow rate.

[0023] The utility model embodiment has the following beneficial effects:

[0024] The stirring part for cold drink equipment of the utility model embodiment is provided with shaft 1 and stirring blade 2, the number of the stirring blade 2 is multiple, multiple the stirring blade 2 is distributed along the axial direction of the shaft 1, the position of multiple the stirring blade 2 in the axial direction of the shaft 1 is staggered, and the side of adjacent stirring blade 2 does not link each other, which makes the distance between adjacent stirring blade 2, that is, the stirring blade 2 is equipped with flow space 4 in the side of the axial direction of the shaft 1, when stirring solid-liquid mixture, solid-liquid mixture can flow through the flow space 4, and the position of multiple the stirring blade 2 in the axial direction of the shaft 1 is staggered, which can ensure that solid-liquid mixture along the axial direction of the shaft 1 can be stirred, which not only ensures that solid-liquid mixture has sufficient flow space 4 and improves the flow rate of solid-liquid mixture, but also ensures stirring uniformity and improves the quality of solid-liquid mixture.

[0025] Specifically, the root 21 of the stirring blade 2 is connected to the lateral wall of the shaft 1, the extension 22 of the stirring blade 2 bends outwardly from the root 21 towards the radial direction of the shaft 1, which enables the stirring blade 2 to generate a pushing force on the solid-liquid mixture in the radial direction, and the adjacent stirring blades 2 are arranged in axial staggered manner, which ensures that the side edges of the adjacent stirring blades 2 do not overlap, thereby forming a continuous through-flow channel between the adjacent stirring blades 2. The cross-sectional area of the channel is significantly larger than that of the conventional laminated blade arrangement, which can effectively improve the flowability of the solid-liquid mixture.

[0026] The rotary shaft 1 has an inlet end 11 and an outlet end 12, one side of the stirring blade 2 is a pressure side 23, which directly generates a pushing force on the solid-liquid mixture, the other side of the stirring blade 2 is a back pressure side 24, which is opposite to the pressure side 23 and does not directly generate a pushing force on the solid-liquid mixture, the stirring blade 2 is curved and inclined from the end close to the inlet end 11 to the end close to the outlet end 12, and the inclination direction of the stirring blade 2 is from the pressure side 23 to the back pressure side 24.

[0027] The outer edge of the extension 22 of the stirring blade 2 is a part of a spiral line, and the axis of the spiral line coincides with the axis of the rotary shaft 1. The spiral line outer edge forms a continuous tangential velocity gradient when the stirring blade 2 rotates, and when the solid-liquid mixture contacts the spiral curved surface, the solid-liquid mixture can push the material in the spiral rise angle direction under the combined action of the centrifugal force and the curved surface normal force, forming directional flow, and the crushing process of ice crystal particles shows a progressive refinement feature, rather than excessive crushing caused by instantaneous impact or unbroken area residues.

The equal pitch makes the strength of the propulsion force that the solid-liquid mixture receives when moving axially remain constant, ensuring that the movement process of the material from feeding to discharging is smooth and continuous, so that the ice crystal particles experience the same frequency of breaking force, and the final particle size distribution is more concentrated. The helical lines where the first outer edge 251, the second outer edge 261 and the third outer edge 271 are located do not coincide with each other, that is, the first outer edge 251 is located at the corresponding position of the feeding section 13 of the first helical line, the second outer edge 261 is located at the corresponding position of the middle section 14 of the second helical line, and the third outer edge 271 is located at the corresponding position of the discharging section 15 of the third helical line. By staggering the arrangement, the pressure wave peaks / troughs of each blade can be staggered, thereby improving the degree of confusion of stirring and significantly improving the uniformity of mixing.

[0030] Referring to Figure 3 , one side of the first blade 25 close to the discharging end 12 is provided with a first flow space 41, both sides of the second blade 26 are provided with a second flow space 42, and both sides of the third blade 27 are provided with a third flow space 43.

The pitch of the helical line where the discharging blade 3 is located is further reduced to enhance the end shearing effect, thereby improving the axial pushing effect on the solid-liquid mixture and enabling the solid-liquid mixture to be quickly discharged.

[0032] Referring to Figure 4The outer edge of the stirring blade 2 is provided with an inclined surface 28 connected with the back pressure side 24, which extends from the back pressure side 24 to the outside of the stirring blade 2 and is inclined towards the direction close to the pressure side 23, forming a sharp fluid guide edge, so as to scrape the gap between the outside of the stirring blade 2 and the storage cover, preventing material residues from being generated on the inner wall of the storage cover.

[0033] The stirring part for cold beverage equipment comprises a rotating shaft 1 and stirring blades 2, the number of the stirring blades 2 is multiple, the multiple stirring blades 2 are distributed along the axial direction of the rotating shaft 1, the positions of the multiple stirring blades 2 in the axial direction of the rotating shaft 1 are staggered with each other, and the side parts of adjacent stirring blades 2 are not connected with each other, so that a certain distance is formed between the adjacent stirring blades 2, that is, the stirring blade 2 is provided with a flow space 4 on one side in the axial direction of the rotating shaft 1, when the solid-liquid mixture is stirred, the solid-liquid mixture can flow through the flow space 4, and the positions of the multiple stirring blades 2 in the axial direction of the rotating shaft 1 are staggered with each other, so that the solid-liquid mixture along the axial direction of the rotating shaft 1 can be stirred, the solid-liquid mixture is ensured to have sufficient flow space 4, the flow rate of the solid-liquid mixture is improved, the stirring uniformity is ensured, and the quality of the solid-liquid mixture is improved.
