[0037] In summary, the mixing tank body 1 takes the tank body 101 as the core bearing space. When the ice cream liquid needs to be heated and sterilized, the heating coil 107 is connected to the external power supply, and the current passes through the heating coil 107 to make it heat up, and the heat is transferred to the liquid inside the tank body 101, thereby increasing the temperature of the liquid and achieving the purpose of sterilizing the liquid. If a cooling and aging operation is to be performed, the refrigeration coil 108 is energized, and the refrigeration coil 108 plays a cooling role, absorbing the heat inside the tank body 101, and reducing the temperature of the liquid to a temperature range suitable for aging. The feeding port 103 of the tank cover 102 is used to add liquid to the inside of the tank body 101, and the discharge port 105 of the tank bottom 104 is used to discharge liquid in the tank body. After uniform mixing, it is discharged. The anti-sticking layer inside the tank body 101 is made of 316L stainless steel.

When it is necessary to add ingredients to the ice cream liquid, the ingredients to be added are put into the feeding hopper 215 in the crushing mechanism 2. At the same time, the transmission motor 212 is powered on and started, driving the shaft 211 to rotate. When the shaft 211 rotates, it drives the sieve plate 208 to do reciprocating motion in the slide frame 207 through the connecting rod 210. During the shaking process of the sieve plate 208, the crushed ice cream ingredients on it are The ingredients are shaken synchronously, which can spread the chopped ingredients on the sieve plate 208, making it easier for the ultraviolet lamp 206 to sterilize the crushed ingredients. If nut ingredients are crushed, nut skin debris will fall from the sieve holes of the sieve plate 208 to the collection box 205 below, preventing nut skin debris from entering the tank body 101 and affecting the quality of the ice cream liquid. On the other hand, when the shaft 211 rotates, it will drive the first transmission wheel 213 to rotate. The first transmission wheel 213 drives the second transmission wheel 219 to rotate through the transmission belt. The second transmission wheel 219 then drives the transmission rod 216 on the right side of the feeding hopper 215 to rotate. The right transmission rod 216 is rotated through the second The transmission belt 221 drives the third transmission wheel 220 on the left to rotate synchronously, thereby causing the left transmission rod 216 to rotate as well. The knife wheels 217 staggered on the two transmission rods 216 rotate synchronously therewith, and cut the ice cream ingredients fed from the feeding hopper 215 into pieces. The cut ingredients enter the tank body 101 through the right side of the crushing shell 203. At the same time, the ultraviolet lamp 206 inside the crushing shell 203 performs preliminary sterilization on the crushed ingredients, and the reset spring auxiliary connecting rod 210 on the left side of the inner wall of the sliding frame 207 resets the sieve plate 208 after it moves, thereby ensuring that the sieve plate 208 continues to move back and forth stably, thereby improving the movement stability of the sieve plate 208.

The rear ends of the two clamping rods 3069 are slidably connected to the inside of the support shell 30610, and the sleeve 3067 is sleeved on the top end of the outer wall of the stirring rod 302, and the bottom ends on the left and right sides of the outer wall of the sleeve 3067 are fixed to the inner side of the top end of the two groove tubes 3063.

[0040] In summary, when mixing the ice cream liquid, the transmission motor 2 301 is installed at the top center of the tank cover 102 through the flange, and its bottom output shaft is fixedly connected to the stirring rod 302. After starting the transmission motor 2 301, the stirring rod 302 rotates, driving the dispersion blades 304 and the blocking cover 303 fixed at its bottom to rotate. During the rotation process, the dispersion blades 304 and the blocking cover 303 produce stirring, shearing and turbulent effects on the ice cream liquid, so that the water, milk powder, sugar, oil and other raw materials in the liquid are fully mixed to avoid the phenomenon of local uneven concentration. The outer wall of the stirring rod 302 is provided with a beveled barrel 305, and its bottom end is fixed to the bottom end of the inner bottom of the tank bottom 104 The top of the stirring rod 302 is provided with a scraping stirring member 306. When the ice cream liquid is aged, the servo motor 30612 drives the gear 30611 to rotate. During the rotation of the gear 30611, the two clamping rods 3069 can be driven to move at the same time, so that the clamping rod 3069 is clamped to the top of the outer wall of the stirring rod 302. As the stirring rod rotates, the two grooved tubes 3063 can be driven to rotate, and then the grooved tubes 3063 drive the scraping stirring blades 3066 to rotate, which can scrape the inner wall of the tank body 101 for stirring. The bottom of the slider 2 3064 in the scraping stirring member 306 is attached to the top of the oblique tube 305. The outer side is connected to the scraping stirring blade 3066 through the fixed block 3065, and the outer side of the scraping stirring blade 3066 is in contact with the inner wall of the tank body 101. When the stirring rod 302 rotates, it drives the groove tube 3063 and the slider 1 3062 to rotate in the annular slide 3061. At the same time, the slider 2 3064 is in contact with the top of the oblique tube 305 at the bottom, and will slide up and down with the change of the inclination of the oblique tube 305, thereby making the scraping stirring blade 3066 rotate along the inner wall of the tank body 101 and perform a compound motion of up and down reciprocating, thereby achieving scraping stirring inside the tank body 101, which can prevent the material liquid from freezing and adhering to the inner wall during the aging process of the tank body 101, and can also clean the tank after the mixing is completed. The interior of the body 101 is cleaned, and the sleeve 3067 is sleeved on the top of the outer wall of the stirring rod 302. The clamping rod 3069 is slidably connected in the sleeves 3068 on the left and right sides of the outer wall, which can clamp and fix the top of the stirring rod 302. The gear 30611 in the support shell 30610 on the back of the outer wall of the sleeve 3067 is driven by the servo motor 30612, which can drive the clamping rod 3069 to move and adjust. In addition, a plurality of counterweights 30613 are set at the front end of the sleeve 3067 to balance the weight of the front and rear ends of the sleeve 3067, ensuring that the sleeve 3067 is more stable when rotating with the stirring rod 302, thereby improving the stability and reliability of the operation of the entire mixing mechanism 3.

[0041] For example three, please refer to Figures 1-9As shown, the first embodiment and the second embodiment are combined to obtain the present embodiment. The mixing tank body 1 is centered around the tank body 101, and the heating coil 107 and the cooling coil 108 wound around the inside of the tank body 101 are key to temperature control. When the ice cream liquid needs to be heated and sterilized, the heating coil 107 is connected to an external power source, and the current passes through the heating coil 107 to generate heat, which is then transferred to the liquid inside the tank body 101, thereby raising the liquid temperature and achieving the purpose of sterilizing the liquid. If a cooling and aging operation is to be performed, the cooling coil 108 is energized, and the cooling coil 108 plays a cooling role, absorbing the heat inside the tank body 101, and lowering the liquid temperature to a temperature range suitable for aging. The feed port 103 of the tank cover 102 is used to add liquid to the inside of the tank body 101, and the discharge port 105 of the tank bottom 104 discharges the liquid after it is evenly mixed. The inside of the tank body 101 adopts an anti-sticking layer made of 316L stainless steel. Since the surface roughness is less than 0.4 microns, it can effectively prevent the material from adhering to the inner wall of the tank body 101, ensuring smooth flow of the material liquid and facilitating cleaning and processing.

[0042] When ingredients need to be added to the ice cream liquid, the ingredients are put into the feeding hopper 215 in the crushing mechanism 2. At this time, the transmission motor 212 is powered on and started, driving the shaft 211 to rotate. The rotation of the shaft 211 has two effects: on the one hand, the shaft 211 drives the sieve plate 208 to reciprocate in the slide frame 207 through the connecting rod 210. During the shaking process of the sieve plate 208, the crushed ice cream ingredients on it are shaken synchronously, which can spread the chopped ingredients on the sieve plate 208, making it easier for the ultraviolet lamp 206 to sterilize the crushed ingredients; if the ingredients are crushed nuts, the nut skin debris will fall from the sieve holes of the sieve plate 208 into the collection box 205 below (the roller in the slot 204 supports the collection box 205 so that it can slide in the slot 204), preventing the nut skin debris from entering the tank body 101 and affecting the quality of the ice cream liquid. Meanwhile, the rotation of the shaft 211 drives the first transmission wheel 213, which in turn drives the second transmission wheel 219 via a transmission belt. The second transmission wheel 219 then drives the transmission rod 216 on the right side of the feed hopper 215. The right transmission rod 216 then drives the third transmission wheel 220 on the left side via a second transmission belt 221, which in turn rotates the left transmission rod 216. The staggered cutter wheels 217 on the two transmission rods 216 then rotate synchronously, chopping the ice cream ingredients fed from the feed hopper 215. The chopped ingredients enter the tank body 101 through the right side of the crushing shell 203. Simultaneously, the ultraviolet lamp 206 inside the crushing shell 203 performs a preliminary sterilization on the crushed ingredients. Furthermore, a return spring on the left side of the inner wall of the slide frame 207 assists the connecting rod 210 in returning the sieve plate 208 to its original position after movement, ensuring its continuous and stable reciprocating motion.

[0043] During the mixing process of the ice cream liquid, a second transmission motor 301 is mounted via a flange at the center of the top of the tank lid 102, with its bottom output shaft fixedly connected to the stirring rod 302. After the second transmission motor 301 is activated, the stirring rod 302 rotates, driving the dispersion blades 304 and the barrier cover 303 fixed at its bottom end to rotate. During the rotation, the dispersion blades 304 and the barrier cover 303 produce stirring, shearing, and turbulent effects on the ice cream liquid, ensuring that the water, milk powder, sugar, and oil in the liquid are fully mixed, avoiding the occurrence of localized concentration unevenness. The outer wall of the stirring rod 302 is provided with an oblique barrel 305, the bottom of which is fixed to the center of the bottom end of the tank bottom 104. The top of the stirring rod 302 is provided with a scraping stirring member 306. The bottom of the slider 2 3064 in the scraping stirring member 306 is affixed to the top of the oblique barrel 305, and the outer side is connected to the scraping stirring blade 3066 via a fixing block 3065. The outer side of the scraping stirring blade 3066 is affixed to the inner wall of the tank body 101. When the stirring rod 302 rotates, it drives the groove tube 3063 and the slider 1 3062 to rotate in the annular slide 3061. At the same time, the slider 2 3064 will slide up and down as the inclination of the beveled tube 305 changes due to its bottom contact with the top of the beveled tube 305, thereby causing the scraping stirring blade 3066 to rotate along the inner wall of the tank body 101 and perform a compound motion of up and down reciprocating motion, thereby achieving scraping and stirring of the inside of the tank body 101, which can not only prevent the material liquid from freezing and adhering to the inner wall of the tank body 101 during aging processing, but also clean the inside of the tank body 101 after mixing is completed. The shaft sleeve 3067 is sleeved on the top of the outer wall of the stirring rod 302, and the clamping rod 3069 is slidably connected in the sleeves 3068 on the left and right sides of the outer wall, which can clamp and fix the top of the stirring rod 302. The gear 30611 in the support shell 30610 on the back of the outer wall of the shaft sleeve 3067 is driven by the servo motor 30612, which can drive the clamping rod 3069 to move and adjust. In addition, a plurality of counterweights 30613 are set at the front end of the shaft sleeve 3067 to balance the weight of the front and rear ends of the shaft sleeve 3067, ensuring that the shaft sleeve 3067 is more stable when rotating with the stirring rod 302, thereby improving the stability and reliability of the operation of the entire mixing mechanism 3.
