[0038] The above ultrasonic water-cooling conveying system can drive the conveying device by the transmission motor to convey the articles through the conveying channel in the bin body, and the ultrasonic generating device arranged at the position of the conveying channel can provide ultrasonic waves for the articles to realize the optimization of the performance of the articles by the ultrasonic waves; especially for the single-cup solidified fermented milk, the system of the solidified fermented milk does not need to be changed, and the structure of the utility model is directly applied to the transmission process after the fermentation of the solidified fermented milk, and the hardness and gel strength of the solidified fermented milk can be effectively reduced by the mechanical effect and cavitation effect of the ultrasonic waves, so that the solidified fermented milk has a softer texture performance, and the taste performance of the solidified yogurt in the sucking degree is improved.

[0039] But the internal temperature of the fermented milk is increased after the ultrasonic treatment, which is not conducive to the overall taste improvement; as an optional implementation mode, as shown in Figure 2 The water inlet and the water outlet of the ultrasonic conveying bin 2 are respectively communicated with the inlet and the outlet of the circulating water cooling equipment. Since the utility model also includes the circulating water cooling equipment, the cooling water can be injected into the conveying channel by the circulating water cooling equipment, the articles treated by the ultrasonic waves are cooled by the circulating cooling water, and the defects caused by the temperature increase after the ultrasonic treatment are reduced. For the solidified fermented milk, the system of the utility model can cooperate with the conveying channel in the ultrasonic conveying bin and the circulating water cooling equipment through the ultrasonic generating device, be applied to the cooling and cooling equipment position of the preparation system of the solidified fermented milk, replace the cooling and cooling equipment, and the setting can realize the improvement of the texture of the solidified fermented milk while avoiding the taste defects caused by the ultrasonic temperature rise in the transmission process of the cooling and cooling after the fermentation of the solidified fermented milk, and effectively improve the taste of the fermented solidified yogurt in the cup. Specifically, for the solidified fermented milk, the mechanical energy part of the ultrasonic treatment alone will become heat energy loss, causing the temperature of the treated sample to rise, the fermentation cannot be stopped at the fermentation end point in time, the acidity is high, the taste performance is poor, and the overall sensory score is low; and the setting of the circulating water cooling equipment can inject cooling water into the conveying channel to solve the problem of poor taste performance caused by the temperature rise of the sample and improve the taste of the solidified fermented milk.

As a preferred configuration, the dewatering module mainly includes two parts: a fan and a draining tray. Specifically, the dewatering module includes a draining tray 5, a fan 6 positioned above the tray 5, and a bracket 7 for adjusting the position of the fan 6. The fan includes a fan frame and fan blades. The bracket 7 is connected to the fan frame via bearings to form an integral structure. The bracket 7 is a movable support rod. The draining tray is a stainless steel tray with evenly distributed drain holes.

[0042] As a feasible transmission method, the transmission device 3 includes a transmission belt, a drive pulley and a transmission pulley for driving the transmission belt, and the motor shaft of the transmission motor 4 is connected to the drive pulley via a coupling. The transmission motor 4 can be installed inside or outside the chamber; preferably, the transmission motor 4 is installed outside the ultrasonic transmission chamber 2. When the transmission motor 4 is installed outside the ultrasonic transmission chamber 2, it can be connected to the transmission motor 4 via a coupling through the drive pulley that extends out of the chamber, or the transmission shaft of the transmission motor 4 can pass through the chamber and be connected to the drive pulley via a coupling, or a coupling can be installed on the chamber, with the transmission motor 4 connected to the drive pulley via the coupling on the chamber. To achieve a waterproof and sealing effect, the coupling is installed on the chamber via a shaft seal. The shaft seal material is preferably wear-resistant, aging-resistant, and corrosion-resistant fluororubber FKM, and the wires inside the chamber are all wrapped with waterproof coatings, such as conformal coating or polyurethane.

[0043] Since the entire conveyor device 3 is immersed in water, the conveyor device 3 is made of high-strength wear-resistant materials that can resist water erosion and corrosion, such as PVC and PU. In order to ensure that the products are effectively transported with the conveyor belt, anti-slip parts are added to the surface of the conveyor belt, such as adding anti-slip textures or coatings. This setting can ensure that the items on the conveyor belt can be transported normally.

[0044] In order to achieve better ultrasonic effect in the transmission process, the transmission direction of the transmission device 3 is the first direction, the bin body has a first side and a second side arranged along the first direction and located on the opposite sides of the transmission device 3 respectively, and more than two ultrasonic generating devices 1 are arranged on the first side and the second side along the transmission direction of the transmission device 3 respectively. Preferably, the width direction of the transmission device 3 is the second direction, the projection of the ultrasonic generating device 1 on the first side in the second direction is a first projection, the projection of the ultrasonic generating device 1 on the second side in the second direction is a second projection, the first projection and the second projection are arranged at intervals, as shown in Figure 2 The first projection and the second projection are arranged at intervals, as shown in

[0045] As a better arrangement, the water inlet of the ultrasonic transmission bin 2 is arranged at the transmission end of the transmission device 3, and the water outlet of the ultrasonic transmission bin 2 is arranged at the transmission start end of the transmission device 3. Through the above arrangement, the cooling effect of the cooling water on the articles on the transmission device 3 can be effectively improved, and when applied to the preparation system of the solidified fermented milk, the overall taste of the solidified fermented milk can be better improved.

[0046] In order to verify the advantages of the ultrasonic water-cooled conveying system of the present application applied to the preparation system of the solidified fermented milk, the ultrasonic water-cooled conveying system of the present application is directly used to replace the cooling and cooling equipment in the present application. The preparation system of the solidified fermented milk comprises a sterilization device, a canning device, a fermentation device and a cooling and cooling device arranged in sequence.

[0047] The original preparation system of the solidified fermented milk, i.e. the ultrasonic water-cooled conveying system, replaces the cooling and cooling equipment in the preparation system of the solidified fermented milk, and obtains the processed product 0. In the present application, the processing method after the ultrasonic water-cooled conveying system replaces the cooling and cooling equipment is two kinds, one is to only start the transmission device 3, the ultrasonic generating device 1 and the circulating water cooling equipment in the ultrasonic water-cooled conveying system, and keep the circulating water temperature at room temperature, to obtain the processed product 1; the other is to simultaneously start the transmission device 3, the ultrasonic generating device 1 and the cooling device 9 in the ultrasonic water-cooled conveying system to reduce the temperature of the cooling water to 4℃, to obtain the processed product 2.

[0048] The hardness and gel strength of the above-mentioned processed products 0-2 are detected, the hardness directly represents the maximum force required by the teeth to compress the product, and the gel strength represents the solidification strength of the solidified yogurt, and the detection results are shown in Table 1. At the same time, the products are subjected to sensory evaluation, the evaluation standard is shown in Table 2, and the evaluation results are shown in Table 3.

[0049] Hardness and gel strength detection method: TPA texture analyzer is used, TA11 / 1000 standard cylindrical probe is used, pre-measurement speed is 1.0mm / s, test speed is 1.0mm / s, post-measurement speed is 1.0mm / s, punch depth is 15mm, time is 10s, trigger force is 0.1g.

[0050] The process of sensory evaluation is that 28 people who have been trained in professional senses respectively evaluate the organization state, taste performance and flavor aroma of the sample, each score is 10 points, and finally the average score of each item is summed up.

[0058] From Table 1, it can be seen that the gel strength and hardness of the treated products 1 and 2 after ultrasonic treatment are lower than those of the treated product 0 within the shelf life, proving that ultrasonic treatment can effectively improve the sucking degree of the set-type fermented milk. It can be seen from the sensory evaluation score in Table 3 that the circulation water cooling treatment of the fermented milk by opening the cooling device can stop fermentation in time at the fermentation end point, and improve the taste performance. The utility model combines ultrasonic treatment with water cooling to realize the cooling of the fermented milk while realizing the ultrasonic treatment, avoiding the continuous fermentation and flavor change caused by the temperature rise of the ultrasonic treated fermented milk.

[0059] In summary, the utility model uses water cooling combined with ultrasonic treatment of the set-type fermented milk before maturation, which can effectively reduce the hardness and viscoelasticity of the set-type fermented milk, give the set-type fermented milk a softer texture, and finally bring better taste performance to consumers.
