Description

Technical Field

[0001] The invention relates to the technical field of mixers, in particular to a bidirectional mixer for dairy product production. Background Art

[0002] Dairy products refer to various foods made from cow's milk or goat's milk and their processed products as the main raw materials, with or without appropriate amounts of vitamins, minerals and other auxiliary materials, and processed under the conditions required by laws, regulations and standards. They are also called cream products. Dairy products include liquid milk (pasteurized milk, sterilized milk, modulated milk, fermented milk); milk powder (whole milk powder, skimmed milk powder, partially skimmed milk powder, modulated milk powder, bovine colostrum powder); other dairy products (etc.); dairy products are stirred using a blender, which is divided into one-way stirring and two-way stirring.

[0003] However, at present, when dairy products are stirred by a two-way mixer, milk is directly added from the top of the stirring tank. During the pouring process, gas and liquid will contact with each other, thereby generating foam. If the amount of foam generated is greater than the amount of foam that breaks, and milk is always added to the same place, the foam will be concentrated in one place, and the foam will gradually accumulate and appear, and the milk will overflow before reaching the stirring amount. In addition, some freshly squeezed fresh milk is directly added to the inside of the stirring tank before stirring, and some debris in the milk is not cleaned up, which is easy to block the discharge pipe during discharge, affecting the discharge of milk.

[0015] The beneficial effects of the present invention are:

[0016] (1) The bidirectional mixer for dairy product production described in the present invention has a stirring mechanism inside the stirring tank that can stir in both directions at the same time, so that the milk inside the stirring tank can be stirred more quickly and evenly. In addition, a filtering mechanism is inside the stirring tank. On the one hand, it can filter out impurities inside the newly squeezed milk to avoid clogging the stirring tank when the milk is discharged. On the other hand, fresh milk can be added to the filtering mechanism when adding materials to achieve preliminary foam removal, so as to facilitate the milk to enter the stirring tank.

When the filter screen rotates, the milk defoaming agent is connected to the water inlet pipe. The defoaming agent can be sprayed from the water outlet of the water pump into the inner part of the outer shell. Since the filter screen is rotating, the water pump can continuously spray the defoaming agent to the filter screen, so that the foam can be processed in time.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 9As shown, a bidirectional mixer for dairy product production described in the present invention comprises a mixing tank 1, a mixing mechanism 2 installed on the mixing tank 1, a transmission mechanism 4 is provided on the mixing mechanism 2, a filtering mechanism 3 is rotatably connected inside the mixing tank 1, the filtering mechanism 3 is connected to the transmission mechanism 4, a defoaming mechanism 5 is installed on the mixing tank 1, and the defoaming mechanism 5 extends to the inside of the filtering mechanism 3; the filtering mechanism 3 comprises a rotating ring 303, a rotating ring 303 is rotatably connected inside the mixing tank 1, a protective ring 301 located inside the mixing tank 1 is fixedly connected to the rotating ring 303, and a filter screen 302 of an annular structure is installed at the bottom of the protective ring 301; when the filter screen 302 is moved toward the mixing tank 1, the filter screen 302 is moved toward the mixing tank 1. When fresh milk is added inside, the outlet of the milk discharge pipe can be connected to the top of the filter 302. When the milk is discharged, it is filtered by the filter 302. The filter 302 can filter impurities in the freshly squeezed milk, avoiding the milk discharge port being blocked and unable to be discharged. The setting of the filter 302 can isolate the foam when the milk is loaded, avoiding it from entering the interior of the stirring tank 1, and the filter 302 can be rotated, which is conducive to discharging milk at different positions of the filter 302, and also avoiding the accumulation and overflow of foam in the same place. Finally, the foam can be blocked when adding materials, avoiding entering the interior of the stirring tank 1 to affect the stirring of the milk, and also avoiding a large amount of foam overflowing.

[0032] Specifically, Figure 1 , Figure 4 and Figure 5As shown, the transmission mechanism 4 includes a transmission shaft 401, the outer wall of the stirring tank 1 is rotatably connected with the transmission shaft 401, a first pulley 403 is installed on the top of the transmission shaft 401, a second pulley 406 is installed on the stirring mechanism 2, a belt 404 is connected between the first pulley 403 and the second pulley 406, a gear ring 405 is fixedly connected to the protective ring 301, a toothed disc 402 is fixed on the transmission shaft 401, and the toothed disc 402 is meshed with the gear ring 405; the diameter of the first pulley 403 is greater than the diameter of the second pulley 406, and the diameter of the first pulley 403 is greater than the diameter of the toothed disc 402; the bottom of the toothed ring 405 conflicts with the top of the stirring tank 1, and the toothed ring 405 is located on the outer wall of the protective ring 301; The machine 203 drives the driving gear 209 to rotate, and at the same time drives the second pulley 406 on the top of the inner shaft 206 to rotate. Since the belt 404 is connected between the first pulley 403 and the second pulley 406, when the second pulley 406 is driven, the belt 404 drives the first pulley 403 to rotate. When the first pulley 403 rotates, it drives the toothed disk 402 on the transmission shaft 401 to rotate. When the toothed disk 402 rotates, it drives the toothed ring 405 on the protective ring 301 to rotate, thereby realizing the rotation of the filter 302. When milk is added, it also realizes contact with the filter 302 at different positions. On the one hand, it can break part of the foam, and on the other hand, it avoids the accumulation of foam in one place. And it rotates with the rotation of the inner shaft 206, realizing the synchronization of stirring and foam removal.

[0033] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the stirring mechanism 2 includes two mounting seats 201, and the side walls of the stirring tank 1 are relatively fixedly connected to the two mounting seats 201, and the two mounting seats 201 are fixedly connected to the brackets 202 by screws, and the brackets 202 are fixedly connected to the fixing frame 204, and the fixing frame 204 is rotatably connected to the outer shaft 205, and the outer shaft 205 is fixedly connected to a connecting frame 207 rotatably connected to the bottom of the stirring tank 1, and the outer shaft 205 is fixedly connected to a first driven gear 210, and a motor 203 is installed on the bracket 202, and the output end of the motor 203 is fixed with a driving gear 209 through a coupling, and the driving gear 209 is meshed with the first driven gear 210; the stirring mechanism 2 also includes an inner shaft 206, and the inner shaft 206 that penetrates the outer shaft 205 is rotatably connected to the fixing frame 204, and the top of the inner shaft 206 is fixed to the second pulley 406, and the inner shaft 206 is fixed There is a second driven gear 211, the driving gear 209 is meshed with the second driven gear 211, and stirring blades 208 are equidistantly installed on the inner wall of the connecting frame 207 and the inner shaft 206; when milk is added to the inside of the stirring tank 1, the motor 203 is started to realize that the motor 203 drives the driving gear 209 to rotate. Since the second driven gear 211 on the inner shaft 206 and the first driven gear 210 on the outer shaft 205 are both meshed with the driving gear 209, and the first driven gear 210 and the second driven gear 211 are arranged oppositely, when the driving gear 209 rotates, the first driven gear 210 and the second driven gear 211 are both driven, and the rotation directions of the two are opposite, so that the connecting frame 207 and the inner shaft 206 rotate in the opposite direction at the same time, and the stirring blades 208 located on the two also stir the milk inside the stirring tank 1 in both directions, thereby improving the stirring speed of the milk and stirring it more evenly.

[0034] Specifically, Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the defoaming mechanism 5 includes a fixed block 501, the side wall of the mixing tank 1 is fixedly connected with the fixed block 501, the fixed block 501 is slidably connected with a sliding column 502, the sliding column 502 is fixedly connected with a top plate 503, an arc-shaped shell 506 is placed inside the protective ring 301, the top plate 503 is fixedly connected to the shell 506, a water pump 505 is installed on the shell 506, and the water pump 505 is connected to a water inlet pipe 504 for conveying defoaming agent; the defoaming mechanism 5 also includes a partition 507, the inside of the shell 506 is equidistantly fixedly connected with the partition 507 of the arc structure, The multiple water outlets of the water pump 505 are all arranged between two adjacent partitions 507; the defoaming mechanism 5 also includes a ball 508, and the bottom of the shell 506 is equidistantly connected to a plurality of ball 508 that is rollingly connected to the filter 302; a shaking mechanism 6 is provided on the top plate 503, and the shaking mechanism 6 includes a plurality of protrusions 601, and the top annular array of the gear ring 405 is provided with a plurality of protrusions 601 with an arc-shaped structure at the top, and the bottom of the top plate 503 is fixedly connected to a top column 603 with an arc-shaped structure at the bottom, and the top column 603 conflicts with the protrusion 601; the shaking mechanism 6 also includes a spring 602, and the top A spring 602 is clamped between the plate 503 and the fixed block 501; an arc-shaped shell 506 is placed on the protective ring 301, and when milk is added to the filter 302 and rotated, the water inlet pipe 504 can be connected to the milk defoamer, and the water pump 505 sucks the milk defoamer and sprays it from the inner top of the shell 506, and the water outlet is opposite to the surface of the filter 302. As the filter 302 rotates, the sprayed milk defoamer can quickly break the foam on the filter 302, and the arrangement of multiple partitions 507 can separate the accumulated foam on the filter 302 into multiple layers, and the water outlet is located between the multiple partitions 507, which increases the milk defoamer. The contact area between the agent and the foam is beneficial to defoaming, and the ball 508 at the bottom of the shell 506 can reduce the friction between the shell 506 and the filter 302, reduce wear, and facilitate the rotation of the filter 302. When the tooth ring 405 rotates, the multiple protrusions 601 on its top also rotate accordingly. Since a top column 603 is provided at the bottom of the top plate 503, when the tooth ring 405 rotates, the top column 603 intermittently collides with the protrusion 601, which is beneficial to the shaking of the shell 506 and the shaking of the foam in the vertical direction, which is beneficial to the contact between the defoaming agent and the foam, and the spring 602 can assist the resetting of the shell 506 to make the top plate 503 more tense.

[0035] When the present invention is used, first, after milk is added into the mixing tank 1, the motor 203 is started, so that the motor 203 drives the driving gear 209 to rotate. Since the second driven gear 211 on the inner shaft 206 and the first driven gear 210 on the outer shaft 205 are both meshed with the driving gear 209, and the first driven gear 210 and the second driven gear 211 are arranged opposite to each other, when the driving gear 209 rotates, the first driven gear 210 and the second driven gear 211 are both driven, and the rotation directions of the two are opposite, so that the connecting frame 207 and the inner shaft 206 rotate in opposite directions at the same time, and the stirring blades 208 located on the two also stir the milk in the mixing tank 1 in both directions, thereby improving the stirring speed of the milk and stirring it more evenly.

[0036] Then, when adding fresh milk into the mixing tank 1, the outlet of the milk discharge pipe can be connected to the top of the filter 302. When the milk is discharged, it is filtered by the filter 302. The filter 302 can filter impurities in the freshly squeezed milk, avoiding the milk discharge port being blocked and unable to be discharged. The filter 302 can isolate the foam when the milk is fed, avoiding it from entering the mixing tank 1. The filter 302 can rotate, which is conducive to discharging milk at different positions of the filter 302, and also avoiding the accumulation and overflow of foam in the same place. Finally, the foam can be blocked when adding materials, avoiding it from entering the mixing tank 1 to affect the stirring of the milk, and also avoiding a large amount of foam overflowing.

[0037] Next, while the motor 203 drives the driving gear 209 to rotate, it also drives the second pulley 406 on the top of the inner shaft 206 to rotate. Since the belt 404 is connected between the first pulley 403 and the second pulley 406, when the second pulley 406 is driven, the belt 404 drives the first pulley 403 to rotate. When the first pulley 403 rotates, it drives the toothed disc 402 on the transmission shaft 401 to rotate. When the toothed disc 402 rotates, it drives the toothed ring 405 on the protective ring 301 to rotate, thereby realizing the rotation of the filter 302. Then, when milk is added, it can contact the filter 302 at different positions. On the one hand, it can break some foam, and on the other hand, it avoids the accumulation of foam in one place. And it rotates with the rotation of the inner shaft 206, realizing the synchronization of stirring and foam removal.

[0038] Finally, an arc-shaped shell 506 is placed on the protective ring 301. When milk is added to the filter 302 and rotated, the water inlet pipe 504 can be connected to the milk defoamer. The water pump 505 sucks the milk defoamer and sprays it from the inner top of the shell 506. The water outlet is opposite to the surface of the filter 302. As the filter 302 rotates, the sprayed milk defoamer can quickly break the foam on the filter 302. The setting of multiple partitions 507 can separate the foam accumulated on the filter 302 into multiple layers. The water outlet is located between the multiple partitions 507, which increases the contact area between the milk defoamer and the foam. It is beneficial to remove bubbles, and the ball 508 at the bottom of the shell 506 can reduce the friction between the shell 506 and the filter 302, reduce wear, and facilitate the rotation of the filter 302. When the tooth ring 405 rotates, the multiple protrusions 601 on its top also rotate accordingly. Since a top column 603 is provided at the bottom of the top plate 503, when the tooth ring 405 rotates, the top column 603 intermittently collides with the protrusion 601, which is beneficial to the shaking of the shell 506 and the shaking of the foam in the vertical direction, which is beneficial to the contact between the defoaming agent and the foam, and the spring 602 can assist the resetting of the shell 506 to make the top plate 503 more tense.
