[0036] In the traditional dough mixing mode, the bagged flour is placed in a cold store. When the dough is mixed, the flour needs to be manually fed into the dough mixing cylinder. In this mode, the dough mixing efficiency is low, a larger raw material warehouse is needed, and the energy consumption is high. This mode has been gradually replaced by a more industrialized and automated mechanical feeding dough mixing system.

[0037] The existing flour mixing system generally comprises a flour storage tank, an automatic flour metering and discharging assembly and a batch flour mixing cylinder.

[0038] However, the above-mentioned flour mixing system does not have a temperature control assembly and cannot control the temperature of the dough.

[0039] High temperature can cause insufficient water absorption of the dough, which in turn causes the dough to be sticky and lack of elasticity, affects the expansion of gluten and finally causes poor processing properties, rough product organization, dull and lusterless skin, sour and sticky taste and other problems.

[0040] To solve the above-mentioned problem, the utility model provides a flour mixing system, wherein a cooling assembly is arranged in the flour mixing system.

[0041] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0042] With reference to Figure 1 The utility model embodiment provides a flour mixing system, which comprises a cooling assembly 11 and a flour mixing assembly 12.

[0043] The cooling assembly 11 is used for sucking air, cooling the sucked air to form cold air and conveying the formed cold air to the flour mixing assembly 12.

[0044] The flour mixing assembly 12 is used for mixing flour and other materials to form dough and cooling the dough by using the cold air conveyed by the cooling assembly 11.

[0045] In the specific implementation, the air can be cooled to a lower temperature, for example, 5 DEG C to 8 DEG C, after passing through the cooling assembly and then conveyed to the flour mixing assembly 12. The cold air conveyed by the cooling assembly can fully exchange heat with the dough, so that the temperature of the dough can be reduced by 5 DEG C to 10 DEG C.

[0046] In some embodiments, referring to Figure 1 , the dough mixing system can further comprise a purification assembly 13. The purification assembly 13 can be connected with the dough mixing assembly 12, so as to purify the air discharged from the dough mixing assembly 12.

[0047] In some embodiments, referring to Figure 1 , the dough mixing system can further comprise a control assembly 14. The control assembly 14 can be used to detect the temperature of the dough formed in the dough mixing assembly 12, and control the operation of the cooling assembly 11 based on the detection result, so as to adjust the temperature of the cold air delivered to the dough mixing assembly 12.

[0048] In some embodiments, the control assembly 14 can also be used to control the purification assembly 13, so that the air used by the dough mixing assembly 12 can be sufficiently purified before being discharged, reducing air pollution.

[0049] Figure 2 is a detailed structure diagram of the dough mixing system in an embodiment of the present application. Referring to Figure 2 , in an embodiment, the cooling assembly can comprise an evaporator 111, a compressor 112, a condenser 113 and a filter 114; wherein:

[0050] The evaporator 111 is used to inhale air, and utilize the liquid refrigerant output by the condenser to exchange heat with the inhaled air, so as to obtain the cold air;

[0051] The filter 114 is connected with the evaporator 111, and is used to deliver the cold air output by the evaporator 111 to the dough mixing assembly;

[0052] The compressor 112 is connected with the evaporator 111, and is used to compress the refrigerant flowing through the evaporator 111, so as to obtain refrigerant vapor;

[0053] The condenser 113 is connected with the compressor 112, and is used to radiate heat from the refrigerant vapor output by the compressor 112, so as to obtain liquid refrigerant, and deliver the liquid refrigerant to the evaporator 111.

[0054] By using the above cooling assembly, the cold air that can cool the dough is formed by using the air cooling principle, so that the temperature of the dough can be reduced.

[0055] Specifically, the evaporator 111 can include a filtering structure 1111, a pressurizing structure 1112, and a cooling structure 1113. The filtering structure 1111 can be arranged at an air inlet of the evaporator, and thus can filter the air sucked in. The pressurizing structure 1112 can be implemented by using a fan or other pressurizing device, and can pressurize the air sucked in. The cooling structure 1113 can be implemented by using a cold air coil. Liquid refrigerant flows in the cold air coil. The air pressurized can exchange heat with the liquid refrigerant flowing in the cold air coil, and thus the air pressurized can be cooled to form cold air. For example, the air sucked in can be cooled to 2°C by the evaporator 111.

[0056] In a specific implementation, the filter 114 is connected with an air outlet of the evaporator 111, and thus the cold air output by the evaporator 111 can be filtered. The filter 114 can include multiple-stage filters, and thus impurities carried in the cold air can be prevented from mixing into the dough to affect the product quality.

[0057] In an embodiment, referring to Figure 2 , the filter 114 can include a primary filter 1141 and a secondary filter 1142. The primary filter 1141 is connected with an air outlet of the evaporator 111, and is used to perform primary filtering on the cold air output by the evaporator 111. The secondary filter 1142 is connected with an air outlet of the primary filter 1141, and is used to perform secondary filtering on the cold air output by the primary filter 1141 and output to the dough mixing assembly.

[0058] In a specific implementation, the primary filter 1141 can be used to filter larger-sized impurities in the cold air, and the secondary filter 1142 can be used to filter smaller-sized impurities in the cold air. The primary filter 1141 and the secondary filter 1142 can both be implemented by using a screen with ventilation holes. The primary filter 1141 and the secondary filter 1142 are connected in stages, and thus the purity of the cold air output to the dough mixing assembly can be improved, and the product quality can be prevented from being affected by impurities carried in the cold air.

[0059] In a specific implementation, the liquid refrigerant flowing through the evaporator 111 can absorb heat of the air, and thus form low-temperature and low-pressure refrigerant vapor and be input to the compressor 112. The compressor 112 can compress the low-temperature and low-pressure refrigerant vapor to obtain high-temperature and high-pressure refrigerant vapor,

[0060] Specifically, the compressor 112 can be implemented by using a variable frequency compressor. The variable frequency compressor can be connected with the control assembly, and thus can perform frequency conversion under the control of the control assembly. The higher the frequency of the variable frequency compressor, the higher the refrigeration speed and energy consumption of the variable frequency compressor.

[0061] In other embodiments, the compressor 112 can also be implemented as a fixed-frequency compressor, which operates at a fixed frequency.

[0062] In specific implementations, the high-temperature and high-pressure refrigerant vapor is delivered to the condenser 113 through a pipeline. The condenser 113 is usually provided with a heat sink 115, which can be implemented by a fan or the like. The heat sink 115 rotates to release the heat of the refrigerant vapor in the condenser 113 to the air, so that the refrigerant vapor in the condenser 113 becomes liquid refrigerant.

[0063] In some embodiments, the pipeline between the condenser 113 and the evaporator 111 can also be provided with a first electromagnetic valve 116 and a first expansion valve 117. The first electromagnetic valve 116 is used to control the flow of the refrigerant, and the first expansion valve 117 is used to throttle and depressurize the refrigerant.

[0064] Specifically, the first electromagnetic valve 116 can be connected with the control assembly, so as to adjust the opening of the valve under the control of the control assembly, and then change the flow of the refrigerant. The greater the opening of the first electromagnetic valve 116, the greater the flow of the refrigerant, and the more refrigerant input into the evaporator 111, so as to change the temperature of the cold air output by the evaporator 111.

[0065] The first expansion valve 117 is also connected with the control assembly, so as to adjust the opening of the valve under the control of the control assembly, and then change the flow of the refrigerant. Under the action of the first expansion valve 117, the liquid refrigerant output by the condenser 113 is in a low-temperature and low-pressure mist state, which creates conditions for the evaporation of the refrigerant.

[0066] In some embodiments, the pipeline between the condenser 113 and the evaporator 111 can also be provided with a sight glass 118 and a filter structure 119. The refrigerant output by the condenser 113 can be filtered by the filter structure 119 and then output to the sight glass 118 through the sight glass 118. The filter structure 119 can filter out impurities in the refrigerant output by the condenser 113, so as to ensure the refrigeration effect. Through the sight glass 118, the state of the refrigerant in the pipeline can be observed to confirm whether it meets the refrigeration requirements.

[0067] In some embodiments, a dryer 110a and a first separator 110b can be further arranged on the pipeline between the evaporator 111 and the compressor 112. The dryer 110a can dry the refrigerant flowing through the evaporator 111 to absorb the moisture in the refrigerant, so as to facilitate subsequent compression. The first separator 110b is located between the evaporator 111 and the compressor 112, and is used to separate the refrigerant flowing through the dryer 110a into gas and liquid, so as to obtain gaseous refrigerant and deliver it to the compressor 112. In this way, the refrigerant delivered to the compressor 112 is dry refrigerant vapor.

[0068] In some embodiments, a second separator 110c can be arranged on the pipeline between the compressor 112 and the condenser 113. The second separator 110c is used to separate the oil from the refrigerant vapor output by the compressor 112, and deliver the refrigerant vapor after oil separation to the condenser 113.

[0069] By arranging the dryer 110a, the first separator 110b and the second separator 110c, the refrigerant after air heat exchange can be reused after drying, compression and oil removal, so as to reduce the system cost.

[0070] Through the above cooling assembly, cold air can be provided for the dough mixing assembly, so as to cool the dough and make the temperature of the dough meet the product requirements.

[0071] In some embodiments, referring to Figure 2 The dough mixing assembly can include a dough mixing cylinder 121 and a stirring assembly 122. The dough mixing cylinder 121 has a containing cavity for containing flour and other materials. The stirring assembly 122 is located in the dough mixing cylinder 121 and is used to stir the materials in the dough mixing cylinder 121.

[0072] Specifically, the dough mixing cylinder 121 can include a cylinder body and a cylinder cover, and the cylinder cover can be used to open or close the cylinder body. The cylinder body and the cylinder cover are combined to form the containing cavity. The dough mixing cylinder 121 can be provided with a cold air inlet, a cold air outlet and a flour inlet 125. Wherein:

[0073] The cold air inlet of the dough mixing cylinder 121 is connected to the air outlet of the evaporator 111 through a pipeline. An inlet throttle valve 123 is arranged on the pipeline close to the cold air inlet of the dough mixing cylinder 121. The inlet throttle valve 123 can be connected to a control assembly, so that the control assembly can control the air supply to the dough mixing cylinder 121 or stop the air supply to the dough mixing cylinder 121.

[0074] The cold air outlet of the mixing cylinder 121 is connected with the purification assembly through a pipeline, so that the used cold air in the mixing cylinder 121 can be discharged to the purification assembly. An outlet throttle valve 124 is arranged on the pipeline close to the cold air outlet of the mixing cylinder 121, which can be connected with the control assembly, so that the control assembly can control the discharge of the cold air to the purification assembly or stop the discharge of the cold air to the purification assembly.

[0075] The flour can be added into the containing cavity through the flour inlet 125 of the mixing cylinder 121. Other dry ingredients can be premixed with the flour or added into the containing cavity through the cylinder cover. The mixing cylinder 121 can also be provided with a brine inlet through which brine is introduced into the containing cavity. During the flour falling process, the control assembly can control the inlet throttle valve 123 and the outlet throttle valve 124 to be closed, so as to prevent the dust from entering other assemblies.

[0076] In specific embodiments, the stirring assembly 122 can include a stirring paddle and a stirring drive. The stirring paddle is connected with the driving shaft of the stirring drive, so that the stirring paddle can be driven to rotate. The stirring drive can be connected with the control assembly, so that the control assembly can control the rotation of the stirring drive and the stirring paddle. Before the dough is formed, the flour and other ingredients can be uniformly mixed by the stirring of the stirring assembly 122 to form the dough. After the dough is formed, the dough can be fully contacted with the cold air by the spiral airflow generated by the stirring of the stirring paddle, so that the dough can be heat exchanged and rapidly cooled.

[0077] In some embodiments, the mixing cylinder 121 can be provided with a temperature detector, which can be in contact with the dough and detect the temperature of the dough, so as to control the opening state of the first electromagnetic valve 116, the inlet throttle valve 123 and the outlet throttle valve 124, and control the working frequency of the compressor, so that sufficient cold air can be provided to the mixing cylinder 121 and the residence time of the cold air in the mixing cylinder 121 can be controlled, so as to automatically adjust the temperature of the dough.

[0078] For example, when the temperature of the dough is too high, the frequency of the compressor can be increased and the residence time of the cold air in the mixing cylinder 121 can be prolonged. When the temperature of the dough is too low, the frequency of the compressor can be reduced and the residence time of the cold air in the mixing cylinder 121 can be shortened.

[0079] In specific embodiments, the purification assembly can include a purification tank 131 and a spraying structure 132. Specifically, the purification tank 131 is connected with the cold air outlet of the mixing cylinder 121 through a pipeline, so that the air discharged from the cold air outlet of the mixing cylinder 121 can enter the purification tank 131 for purification.

[0080] The spraying structure 132 can include a spraying member and a spraying member driving structure. The spraying member has a spraying head and a spraying pipe connected to a water source. The spraying head is located at one end of the spraying pipe and is placed in the purification tank 131, and the other end of the spraying pipe is also placed in the purification tank 131. The spraying driving structure can be connected with the spraying pipe, so as to drive the spraying pipe to spray soft water and rotate. The soft water sprayed by the spraying head can be in contact with air in the purification tank 131, so as to wash out dust in the air. The purified air can be discharged from the air outlet 133 of the purification tank 131 to the atmosphere, and the waste water used by the purification tank 131 can be discharged from the sewage outlet 134.

[0081] In some embodiments, the purification assembly can further include a water supplementing structure 135 connected with a water inlet at the top of the purification tank 131 and capable of supplementing the spraying pipe with clean soft water under the control of the control assembly, so as to realize automatic water supplementing.

[0082] From the above, it can be seen that the dough mixing system in the embodiments of the present application can make the dough fully cooled by arranging the cooling assembly. In addition, the dough mixing system does not need to arrange a flour special cold storage, has compact structure, small equipment investment and low energy consumption, can effectively save space, cost and energy consumption. Furthermore, the dough mixing system has high automation degree, does not need complex operation, can automatically control the cooling air temperature and air volume by detecting the dough temperature, realizes equipment automation, and improves production stability and product quality.

[0083] The embodiments of the present application further provide a flour product, which is made of the dough formed by the dough mixing system in any one of the above embodiments. For example, the flour product can be noodles, bread and the like.
