Description

Technical Field

[0001] This utility model belongs to the technical field of compressed biscuit production equipment, and specifically relates to an automatic oil and water supply device for compressed biscuits. Background Technology

[0002] In the preparation of compressed biscuits, the uniformity of mixing between powder and wet materials (i.e., oil and water) directly affects the quality of the compressed biscuits after molding. The amount, proportion, and timing of adding wet materials all directly influence the mixing state. Currently, most compressed biscuit production involves manually weighing out specific amounts of oil and water and adding them separately to the powder before mixing. This results in some powder forming clumps with the oil or water, which is not only labor-intensive but also increases the load on the mixing equipment, prolongs mixing time, and leads to low production efficiency. Furthermore, the friction during mixing can cause the oil to oxidize and become rancid, affecting product quality. In addition, manual addition hinders automated production, severely limiting efficiency improvements. Adding oil and water separately also prevents uniform mixing of the oil and water in the powder, further impacting the final product quality. Utility Model Content

[0003] The purpose of this invention is to propose an automatic oil and water supply device for compressed biscuits, in order to solve the problems of high manual labor intensity, high load on mixing equipment, long mixing time, poor uniformity of oil, water and powder mixing in the existing wet mixing process of compressed biscuit powder, which ultimately affects product quality.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes an automatic oil and water supply device for compressed biscuits, including an oil supply mechanism, a water supply mechanism, a pre-emulsification mechanism, and a stirring device. The oil supply mechanism includes an oil storage tank, an oil outlet pipe, an oil pump, and an oil quantity control valve. The oil outlet pipe connects the oil storage tank and the pre-emulsification mechanism, and the oil pump and oil quantity control valve are located on the oil outlet pipe. The water supply mechanism includes a water storage tank, a water outlet pipe, a water pump, and a flow control valve. The oil outlet pipe connects the water storage tank and the pre-emulsification mechanism, and the water pump and flow control valve are located on the water outlet pipe. The pre-emulsification mechanism is used to form a uniformly distributed oil-water emulsion. The stirring device is equipped with several feeding pipes, which are connected to the pre-emulsification mechanism. The feeding pipes are equipped with nozzles, which are uniformly distributed within the stirring device.

[0006] Based on the above technical solutions, the oil supply mechanism and water supply mechanism are set up to realize automatic oil and water supply to the stirring device according to the amount and proportion, and realize the continuous addition of oil and water during the stirring process. At the same time, through the setting of the pre-emulsification mechanism, the oil and water are pre-mixed to form an emulsion before addition, so that the oil and water are evenly dispersed in the powder in an equal proportion, improving the mixing uniformity of oil, water and wet materials with powder, thereby improving the control accuracy of production parameters, increasing production efficiency and improving the quality stability of compressed biscuit products.

[0007] Preferably, the oil supply mechanism further includes a carburetor, which is equipped with a jacket and a heating coil inside the jacket. The carburetor is connected to the oil storage tank. This design ensures that the oil in the oil supply system maintains good fluidity, which is beneficial to improving production efficiency.

[0008] Preferably, the outer walls of the oil storage tank and the oil outlet pipe are wrapped with heat-insulating material. The purpose of this design is to maintain a certain temperature of the oil during the transmission process, thereby maintaining its fluidity and facilitating the control of the amount of oil added.

[0009] Preferably, the pre-emulsification mechanism is a hollow annular tube, including an inner tube, an outer tube, a first cap, and a second cap. A spiral flow channel is provided between the inner tube and the outer tube. The first cap and the second cap are respectively located on both sides of the inner tube and the outer tube and seal the inner tube and the outer tube. The first cap has a first oil inlet, and the second cap has a first emulsion outlet. The first oil inlet and the first emulsion outlet are connected to the spiral flow channel. A plurality of first water inlets are opened on the side wall of the outer tube. The first water inlets are connected to the spiral flow channel. This design utilizes the fact that after the oil and water enter the spiral flow channel between the inner tube and the outer tube, the oil and water are fully and uniformly mixed due to the continuous change of the flow direction.

[0010] Furthermore, the first and second caps are provided with circulating water inlets, which are connected to the inner cavity of the inner tube. A constant-temperature liquid circulates in the inner cavity of the inner tube. The purpose of this design is to maintain a relatively constant temperature of the mixed liquid in the spiral flow channel through the circulating constant-temperature liquid, so that the temperature is neither too low and stagnant, nor too high due to heat generated by collision, thereby maintaining a more suitable temperature for the mixed liquid.

[0011] Preferably, the pre-emulsification mechanism includes a mixing tank and an ultrasonic device. The mixing tank has a second oil inlet and a second water inlet on one side and a second emulsion outlet on the other side. The ultrasonic device is located on the mixing tank and is used to mix and emulsify the oil and water entering the mixing tank. This design utilizes the ultrasonic device to mix the oil and water, which helps to increase the oil-water mixing speed and also helps to disperse the oil into smaller droplets, resulting in a better mixing and emulsification effect.

[0012] More preferably, the ultrasonic device includes an ultrasonic generator and an ultrasonic probe. The ultrasonic generator is located outside the mixing tank, and the ultrasonic probe is rod-shaped or ring-shaped. The ultrasonic probe is inserted into the mixing tank and located between the second oil inlet and the second emulsion outlet. It is used to directly agitate the liquid in the mixing tank to achieve emulsification. This design can directly form mixed flow in the mixing tank, thereby achieving oil-water mixing.

[0013] More preferably, the ultrasonic device includes an ultrasonic generator and an ultrasonic probe. The ultrasonic probe is set in contact with the wall of the mixing tank. The vibration of the mixing tank wall promotes the mixing of oil and water. This design is conducive to the mixing tank as a whole vibrating at the same frequency, thereby causing the internal liquid to form multi-regional mixed flow and mixing superposition, which is more conducive to accelerating the mixing speed.

[0014] More preferably, the mixing chamber is divided into a premixing zone and an emulsification zone. The premixing zone is connected to the second oil inlet and the second water inlet. The premixing zone is provided with at least one porous plate, which is used to initially disperse the oil in the water to form small-diameter oil droplets. The ultrasonic device is located in the emulsification zone. The purpose of this design is to pre-disperse the oil in the water into smaller-diameter oil droplets through the porous plate before ultrasonic emulsification treatment, which helps to improve the processing efficiency of the ultrasonic device and shorten the processing time.

[0015] Preferably, the oil storage tank and the water storage tank are equipped with a visual level gauge on the outside for observing the remaining liquid level in the oil storage tank and the water storage tank.

[0016] Beneficial effects

[0017] One of the above technical solutions has the following advantages or beneficial effects:

[0018] 1) By setting up oil supply and water supply mechanisms, the mixing device can be automatically supplied with oil and water according to the amount and proportion, and the oil and water can be continuously added during the mixing process. During the mixing process, the oil and water can be in full contact with the powder, which can effectively improve the mixing uniformity of oil, water and powder, reduce the agglomeration rate, thereby reducing the equipment load and improving production efficiency.

[0019] 2) By setting up a pre-emulsification mechanism, oil and water are pre-mixed to form an emulsion before addition. On the one hand, the dispersibility of water is used to improve the dispersibility of oil. On the other hand, by adding oil and water in a mixed manner, oil and water are evenly dispersed in the powder in equal proportions, which improves the mixing uniformity of oil and water wet materials and powder, shortens the stirring time, and thus achieves the purpose of improving the control accuracy of production parameters and improving the quality stability of compressed biscuit products.

[0020] 3) By setting the pre-emulsification mechanism as a combination of an ultrasonic device and a mixing box, the ultrasonic device causes the oil to vibrate and disperse into smaller oil droplets, thereby forming a uniform emulsion state of water-in-oil or oil-in-water, accelerating the oil-water mixing speed and mixing effect, so as to achieve a more uniform mixing state of powder and oil-water wet materials.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides an automatic oil and water supply device for compressed biscuits, including an oil supply mechanism 1, a water supply mechanism 3, a pre-emulsification mechanism 4, and a stirring device 5. The upper cover of the stirring device 5 is provided with a plurality of feeding pipes 6 evenly distributed. The feeding pipes 6 are connected to the pre-emulsification mechanism 4. The feeding pipes 6 are provided with nozzles 7, which are evenly distributed within the stirring device 5.

[0032] The oil supply mechanism 1 includes an oil storage tank 12, an oil outlet pipe 13, an oil pump 14, and an oil quantity control valve 15. A visual level gauge 2 is installed outside the oil storage tank 12 to observe the remaining oil level. The oil outlet pipe 13 connects the oil storage tank 12 and the pre-emulsification mechanism 4. The oil pump 14 and the oil quantity control valve 15 are located on the oil outlet pipe 13. The oil pump 14 draws oil from the oil storage tank 12 to the pre-emulsification mechanism 4. Adjusting the working pressure of the oil pump 14 can adjust the flow rate and pressure in the oil outlet pipe 13. The oil quantity control valve 15 regulates and controls the actual amount of oil supplied to the pre-emulsification mechanism 4 and can set a threshold according to actual production needs. The oil pump 14 and the oil quantity control valve 15 are signal-connected and work together. Preferably, the front end of the oil storage tank 12 is also connected to a carburizing tank 11, such as... Figure 2 As shown, the carburetor 11 is equipped with a jacket 1101, and a heating coil 1102 is installed inside the jacket 1101. The carburetor 11 is used to melt solidified grease into liquid oil. The heating coil 1102 can be circulated with high-temperature water, steam, heat transfer oil, or conventional heating methods such as directly laying heating wires. The heating temperature of the heating coil 1102 is determined comprehensively based on the type of solid grease, melting temperature, etc. Preferably, to ensure that the oil always maintains its fluidity, the outer walls of the oil storage tank 12 and the oil outlet pipe 13 are wrapped with heat-insulating material (not shown in the figure) to maintain the required temperature for the oil to flow during the transmission process.

[0033] The water supply mechanism 3 includes a water storage tank 31, a water outlet pipe 32, a water pump 33, and a flow control valve 34. A visual level gauge 2 is installed on the outside of the water storage tank 31 to observe the remaining water level. The oil outlet pipe 13 connects the water storage tank 31 and the pre-emulsification mechanism 4. The water pump 33 and the flow control valve 34 are located on the water outlet pipe 32. The water pump 33 draws water from the water storage tank 31 to the pre-emulsification mechanism 4. The flow control valve 34 regulates and controls the actual amount of water supplied to the pre-emulsification mechanism 4 and can set a threshold according to actual production needs. The operation of the water pump 33 and the flow control valve 34 is the same as that of the oil pump 14 and the oil quantity control valve 15. Preferably, the water outlet pipe 32 is equipped with a constant temperature heating device such as a water bath (not shown in the attached diagram) near the pre-emulsification mechanism 4, so that the water entering the pre-emulsification mechanism 4 has a certain temperature, preventing the oil from solidifying upon contact with the surface due to excessively low temperature, which would be detrimental to dispersion.

[0034] The pre-emulsification mechanism 4 is used to form a uniformly distributed oil-water emulsion from the oil and water. For example... Figure 3 As shown in the figure, in this embodiment, the pre-emulsification mechanism 4 is a hollow annular structure with inner and outer tubes, including a first cap 4101, an outer tube 4102, an inner tube 4104, and a second cap 4105. A spiral flow channel 4103 is provided between the inner tube 4104 and the outer tube 4102. The first cap 4101 and the second cap 4105 are respectively disposed on both sides of the inner tube 4104 and the outer tube 4102 and close the inner tube 4104 and the outer tube 4102. A sealing structure (not shown in the figure) is provided between the first cap 4101 and the second cap 4105 and the inner tube 4104 and the outer tube 4102 to ensure the overall airtightness of the pre-emulsification mechanism 4. The first cap 4101 is provided with a first oil inlet 4106, and the first oil inlet 4106 is connected to the oil outlet pipe. 13. The second cap 4105 is provided with a first emulsion outlet 4108, which is connected to the feed pipe 6. The first oil inlet 4106 and the first emulsion outlet 4108 are connected to the spiral flow channel 4103. The outer pipe 4102 has several first water inlets 4107 on its side wall. The first water inlets 4107 are located on the side near the first oil inlet 4106. One end of each first water inlet 4107 is connected to the water outlet pipe 32, and the other end is connected to the spiral flow channel 4103. The added water enters from the first water inlet 4107 and is tangentially mixed into the oil to form an initial mixture. The mixture continues to collide and mix as it flows along the spiral flow channel 4103, eventually forming a uniformly mixed emulsion.

[0035] More preferably, the first cap 4101 and the second cap 4105 are provided with a circulating water inlet 4109, which is connected to the inner cavity of the inner tube 4104. A constant temperature liquid circulates in the inner cavity of the inner tube 4104 so that the mixed liquid in the spiral flow channel 4103 maintains a relatively constant temperature, thereby improving the mixing effect and maintaining a suitable temperature for the emulsion formed.

[0036] The advantages of this embodiment are as follows: by setting up the oil supply mechanism 1 and the water supply mechanism 3, the stirring device 5 can be automatically supplied with oil and water according to the amount and proportion, and the oil and water can be continuously added during the stirring process; and by setting up the pre-emulsification mechanism 4 with a hollow ring structure, the oil and water are pre-mixed to form an emulsion before addition, so that the oil and water are evenly dispersed in the powder in an equal proportion, improving the mixing uniformity of the oil, water, wet material and powder, thereby improving the accuracy of production parameter control, improving production efficiency and improving the quality stability of the compressed biscuit product.

[0037] Example 2

[0038] like Figures 4-6 As shown, this embodiment provides an automatic oil and water supply device for compressed biscuits, which differs from Embodiment 1 in that:

[0039] The pre-emulsification mechanism 4 includes a mixing tank 4201 and an ultrasonic device. The mixing tank 4201 has a second oil inlet 4204 and a second water inlet 4205 on one side and a second emulsion outlet 4206 on the other side. The ultrasonic device is located on the mixing tank 4201 and is used to mix and emulsify the oil and water entering the mixing tank 4201. The ultrasonic device includes an ultrasonic generator 4202 and an ultrasonic probe 4203. The ultrasonic generator 4202 is located outside the mixing tank 4201 and is used to provide ultrasonic waves.

[0040] As an optional configuration, the ultrasonic probe 4203 is rod-shaped or ring-shaped. The ultrasonic probe 4203 is inserted into the mixing tank 4201 and located between the second oil inlet 4204 and the second emulsion outlet 4206. That is, the ultrasonic probe 4203 is directly immersed in the liquid in the mixing tank 4201. The mechanical vibration generated after startup directly disturbs the liquid, causing the oil in it to disperse into small oil droplets, thereby forming an oil-in-water or water-in-oil emulsion mixture.

[0041] As another optional configuration, the ultrasonic probe 4203 is directly attached to the wall of the mixing chamber 4201. The vibration generated by the ultrasonic probe 4203 is preferentially transmitted to the wall of the mixing chamber 4201, causing the entire mixing chamber 4201 to vibrate at the same frequency. The vibration is then transmitted to the liquid through the mixing chamber 4201, causing the internal liquid to form multi-regional mixed flow and the vibration to be superimposed, thereby accelerating the mixing speed.

[0042] Furthermore, the mixing tank 4201 is divided into a premixing zone 401 and an emulsification zone 402. The premixing zone 401 is connected to the second oil inlet 4204 and the second water inlet 4205. The premixing zone 401 is provided with at least one porous plate 403. The porous plate 403 is used to initially disperse the oil in the water to form small-diameter oil droplets to improve the processing efficiency of the ultrasonic device and shorten the processing time. The ultrasonic device is located in the emulsification zone 402 to perform ultrasonic refining treatment on the small-diameter oil droplets formed after dispersion to form an oil-water emulsion.

[0043] The advantage of this embodiment is that the high-frequency vibration of the ultrasonic device refines the oil into tiny oil droplets, thereby forming a uniform emulsion state of water-in-oil or oil-in-water, which accelerates the mixing speed and effect of oil and water, and finally achieves a more uniform mixing state of powder and oil-water wet material after being added to the stirring device 5.

[0044] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
