[Specific implementation method]

[0029] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

In addition, the terms "first", "second", etc., etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0031] See also Figures 1 to 5 As shown, the present invention provides a cake raw material pre-preparation device for improving freshness, comprising a base 100, a mixing device 200 and a whipping device, wherein the mixing device 200 and the whipping device are fixedly mounted on the base 100; the mixing device 200 comprises a primary stirring pipe 1, and the whipping device comprises a secondary whipping pipe 2; the output end of the primary stirring pipe 1 and the input end of the secondary whipping pipe 2 are connected by a reducer 3; the inner diameter of the reducer 3 gradually decreases from the primary stirring pipe 1 to the secondary whipping pipe 2.

[0032] The primary mixing mechanism 9 mixes the egg white, light cream, butter and icing sugar and conveys them to the primary mixing mechanism 9 and then enters the primary stirring pipe 1, where the various raw materials are roughly stirred once by a spiral stirring piece. The roughly stirred raw materials are conveyed to the reducing pipe 3. The inner diameter of the reducing pipe 3 is gradually reduced from the primary stirring pipe 1 to the secondary whipping pipe 2, so as to increase the resistance of the raw materials in the reducing pipe 3 and reduce the flow rate, so that the raw materials can be more smoothly transferred to the secondary whipping pipe 2 for a secondary thorough whipping, so that the raw materials are fully mixed until they are whipped into a fluffy state, so that the raw material texture is more delicate, softer and more expandable, thereby improving the freshness of the cake.

[0033] In the present invention, the secondary beating pipe 2 is arranged to be inclined downward from the input end to the output end to facilitate discharge.

[0034] In the present invention, the whipping device further comprises a secondary whipping assembly 4 for secondary whipping the raw materials in the secondary whipping pipe 2; the secondary whipping assembly 4 comprises a plurality of beat-type whipping elements 41, a flip driving mechanism 42 for driving the beat-type whipping elements 41 to flip, and a ventilation mechanism 43 for introducing cold air into the beat-type whipping elements 41; one end of the beat-type whipping element 41 extends into the secondary whipping pipe 2, and the other end is connected to the flip driving mechanism 42. After the raw materials enter the secondary whipping pipe 2, the flip driving mechanism 42 drives the beat-type whipping element 41 to rotate continuously, thereby stirring the raw materials; in addition, the ventilation mechanism 43 supplies cold air to the beat-type whipping element 41, and the cold air is blown out through the beat-type whipping element 41, so that a large amount of cold air is mixed into the raw materials; the secondary whipping assembly 4 integrates stirring and aeration, has a compact structure, expands the raw material structure during the whipping process, and feels softer, thereby improving the freshness. The flipping drive mechanism 42 can control the flipping speed of the beater 41 according to different whipping needs; the ventilation mechanism 43 can control the cold air output speed according to different whipping needs. The flipping drive mechanism 42 is preferably a servo motor.

[0035] In the present invention, the beat-type whipping element 41 includes a connecting rod 411, at least one beat-type frame 412, and a grid frame 413 fixedly connected to the inside of the beat-type frame 412. The connecting rod 411, the beat-type frame 412, and the grid frame 413 are connected to each other; one end of the connecting rod 411 is fixedly connected to the beat-type frame 412, and the other end of the connecting rod 411 is fixedly connected to the flip driving mechanism 42, and a through hole is formed inside the connecting rod 411. The beat-type frame 412 supports the grid frame 413. Since the raw material has an impact force on the beat-type whipping element 41, the beat-type frame 412 improves the structural strength of the beat-type whipping element 41, reduces the impact, and prolongs the service life of the beat-type whipping element 41. The pat-shaped frame 412 extends into the secondary whipping pipe 2 and is a circular structure adapted to the inner wall of the secondary whipping pipe 2; the flip driving mechanism 42 drives the connecting rod 411 to rotate and then drives the pat-shaped frame 412 to flip in the secondary whipping pipe 2. The pat-shaped frame 412 is designed with a circular structure so that the rotation of the pat-shaped frame 412 is smoother and more stable. The side of the grid frame 413 is formed with a plurality of material holes 414 and air outlet nozzles 415, and the inside of the grid frame 413 is formed with a channel for gas flow, and the channel and the air outlet nozzle 415 are connected. After the raw materials pass through the material holes 414, the raw materials are separated, and the air outlet nozzle 415 sprays cold air in this gap. In addition, the pat-shaped whipping member 41 is in a state of continuous flipping at this time, and the sprayed cold air has a certain impact force, so that the cold air forms a disordered airflow in the raw materials, causing impact on the raw materials, increasing the gas content in the raw materials, making the raw materials more soft, and greatly improving the whipping efficiency and effect.

[0036] In the present invention, in order to improve the whipping uniformity effect, the material passing holes 414 and the air outlet nozzles 415 are arranged in an array distribution, and the material passing holes 414 and the air outlet nozzles 415 are arranged one by one.

The air pump 431 is fixedly installed on the base 100, and the output end of the air pump 431 is connected to the connecting pipe 4321. The sleeve 4322 and the wear-resistant ring 4323 cooperate with each other to make the outside of the air inlet hole 416 of the connecting rod 411 sealed. When the connecting rod 411 flips over, the sleeve 4322 does not flip over. At this time, cold air enters the interior of the connecting rod 411 through the air inlet hole 416, and the cold air is ejected along the connecting rod 411, the racket frame 412, the grid frame 413, and the air outlet nozzle 415.

[0038] The secondary whipping assembly 4 of the present invention includes a plurality of beat-type whipping elements 41, a turning drive mechanism 42, and a ventilation mechanism 43, so that the beat-type whipping elements 41 can simultaneously achieve gas exhaust and turning effects, thereby simultaneously stirring and aerating the raw materials, achieving dual purposes in one beat, and can effectively improve the whipping effect and whipping efficiency of the raw materials, making the prepared raw material texture more soft, thereby making the cake more tender.

[0039] In the present invention, in order to improve the whipping efficiency and effect, the beat-type frame 412 is bent, and any beat-type whipping piece 41 includes two beat-type frames 412; the two sides of the two beat-type frames 412 are fixedly connected to each other in an elliptical shape or fixedly connected in the middle in an X-shape.

[0040] In the present invention, in order to further improve the whipping efficiency and effect, the number of the beat-type whipping elements 41 is 3, and the 3 beat-type whipping elements 41 are distributed along the length direction of the secondary whipping tube.

[0041] In the present invention, the secondary whipping assembly 4 further includes a temperature control mechanism 44.

The temperature control mechanism 44 recycles the liquid to avoid waste. The winding pipe 443 is wound around the outer wall of the secondary whipping pipe 2, which can effectively control the temperature inside the secondary whipping pipe 2 within a specified range.

[0044] A cake raw material pre-preparation process for improving freshness and tenderness comprises the following steps:

[0045] Step 1: After egg white, whipping cream, butter and icing sugar are mixed in the mixing mechanism in sequence, they are transported to the primary mixing pipe 1 for rough mixing. The various raw materials are roughly mixed once by the spiral stirring element.

[0046] Step 2: The raw materials after rough mixing are transported to the reducer 3 to reduce the flow rate so that the raw materials can be more smoothly transferred to the secondary beating pipe 2;

[0047] Step three: The secondary beating component 4 beats the raw materials to fully mix them until the raw material structure is in a fluffy state; the temperature control mechanism 44 controls the temperature of the outer wall of the secondary beating pipe 2, the flip drive mechanism 42 drives the patting type beating element 41 to flip and stir, and the ventilation mechanism 43 introduces cold air into the patting type beating element 41.
