Description

Technical Field

[0001] The invention belongs to the technical field of liquid separation, and in particular relates to a nano-level homogenizer. Background Art

[0002] A homogenizer is a device used to homogenize and emulsify liquid materials with a viscosity lower than 0.2 Pa.s and a temperature lower than 100°C. It is mainly used in the homogenization and emulsification processes in the production process of products in the food or chemical industry. At present, in the process of using a homogenizer to homogenize beverages, it is still impossible to make the beverage particles reach the nanometer level. Moreover, after the homogenization is completed, the beverage needs to be subsequently treated with high-temperature sterilization, which will cause the loss of nutritional components of the beverage, reduce the taste and color; beverage particles may agglomerate and stratify during the sterilization process. Therefore, how to design a new type of homogenizer to overcome the above problems is a direction that technicians in this field need to study. Summary of the invention

[0003] The purpose of the present invention is to provide a nano-scale homogenizer that can homogenize beverage particles to the nano-scale without the need for additional high-temperature sterilization equipment, thereby ensuring the taste and nutritional content of the beverage and completing the sterilization function at the same time.

[0004] The technical solutions adopted are as follows:

[0005] A nano-scale homogenizer, comprising: a homogenizing valve, a material storage device, a three-way pipe, a hydraulic cylinder and a pressure-stabilizing chamber; the hydraulic cylinder comprises a low-pressure oil cylinder, a high-pressure cylinder and a piston; one end of the cylinder body of the high-pressure cylinder is provided with an end cover, the end cover is provided with an inlet and outlet hole, and the other end is connected to the low-pressure oil cylinder through a high-low pressure connecting plate; the high-low pressure connecting plate is provided with a through hole; the piston comprises a high-pressure plunger, a cylinder plunger, a plunger connecting block and a piston body; the high-pressure plunger and one end of the cylinder plunger are connected through a plunger connecting block; the cylinder The other end of the plunger is connected to the piston body, and the piston body and the plunger connecting block are located in the low-pressure oil cylinder; the high-pressure plunger passes through the high- and low-pressure connecting plate through the through hole and extends into the high-pressure cylinder; the plunger connecting block is larger than the through hole; the three-way pipe is respectively connected to the inlet and outlet holes, the output end of the accumulator and the input end of the pressure-stabilizing chamber; and a one-way feed valve is provided at the interface between the three-way pipe and the output end of the accumulator; a one-way discharge valve is provided at the interface between the three-way pipe and the input end of the pressure-stabilizing chamber; the output end of the pressure-stabilizing chamber is connected to the input end of the homogenizing valve.

[0006] By adopting this technical solution: the material enters the three-way pipe from the accumulator, the low-pressure oil cylinder is started, and first drives the piston to move in the high-pressure cylinder, and the material entering the three-way pipe enters the cylinder body of the high-pressure cylinder through the feed hole. Then the low-pressure oil cylinder resets, drives the piston to move in the opposite direction in the high-pressure cylinder, and sends the material back to the three-way pipe, and the material is accelerated by the piston to enter the pressure stabilizing chamber from the three-way pipe. The low-pressure oil cylinder continues to repeat the above working process, so that the material moves slowly in the pressure stabilizing chamber, and in this process, the pressure value in the pressure stabilizing chamber is always maintained at 300MPa-600MPa, and the microorganisms in the material are killed under the action of this pressure value. The sterilized material is output from the output end of the pressure stabilizing chamber to the homogenizing valve for homogenization operation.

[0007] Preferably, in the nano-scale homogenizer, the hydraulic cylinder is a double-piston hydraulic cylinder. Specifically, the double-piston hydraulic cylinder includes a first high-pressure cylinder, a low-pressure oil cylinder and a second high-pressure cylinder connected in sequence, and the piston includes a piston body and two groups of symmetrically arranged high-pressure plungers, a cylinder plunger and a plunger connecting block. The two cylinder plungers are respectively connected to the two ends of the piston body.

[0008] By adopting this technical solution: by controlling the rotation of the two high-pressure cylinders, the materials that have completed the homogenization operation through the two-way pipes on both sides are returned to the accumulator and enter the pressure stabilizing chamber again for secondary sterilization. In this way, the sterilization time of the materials in the pressure stabilizing chamber is further increased, the design length and floor space of the pressure stabilizing chamber are reduced, and the particles formed after the homogenization of the materials are smaller and the effect is better.

[0009] More preferably, in the above nano-scale homogenizer: the piston is a ceramic piston.

[0010] The reason for adopting this technical solution is that the ceramic piston has the characteristics of not easy to wear, poor thermal conductivity and high product strength. At the same time, the ceramic piston has a high surface finish and can meet the food grade use requirements of this product.

[0011] It is further preferred that, in the above-mentioned nano-scale homogenizer: the storage container is composed of a plurality of sub-storage containers connected in parallel.

[0012] It is further preferred that, in the above-mentioned nano-scale homogenizer: a low-pressure oil seal is provided in the low-pressure oil cylinder; and a travel switch and a high-pressure seal are provided in the high-pressure cylinder.

[0013] Compared with the prior art, the present invention has a simple structure and is easy to implement. It can homogenize beverage particles to nanometer level without the need for additional high-temperature sterilization equipment, thereby ensuring the taste and nutritional content of the beverage and having a sterilization function.

[0020] In order to more clearly illustrate the technical solution of the present invention, further description will be given below in conjunction with various embodiments.

[0021] like Figure 1-3 Example 1 is shown:

[0022] A nano-scale homogenizer comprises: a homogenizing valve 1, a material storage container 2, a three-way pipe 3, a hydraulic cylinder and a pressure stabilizing chamber 7.

[0023] The hydraulic cylinder comprises a low-pressure oil cylinder 4, a high-pressure cylinder 5 and a piston 6; one end of the cylinder body of the high-pressure cylinder 5 is provided with an end cover 51, the end cover 51 is provided with an inlet and outlet hole 52, and the other end is connected to the low-pressure oil cylinder 4 through a high-low pressure connecting plate 8; the high-low pressure connecting plate 8 is provided with a through hole; the piston 6 comprises a high-pressure plunger 61, a cylinder plunger 62, a plunger connecting block 63 and a piston body 64; one end of the high-pressure plunger 61 and the cylinder plunger 62 are connected through a plunger connecting block 63; the other end of the cylinder plunger 62 is connected to the piston body 64, The piston body 64 and the plunger connecting block 63 are located in the low-pressure oil cylinder 4; the high-pressure plunger 61 passes through the high-low pressure connecting plate 8 through the through hole and extends into the high-pressure cylinder 5; the plunger connecting block 63 is larger than the through hole; the three-way pipe 3 is respectively connected to the inlet and outlet holes 52, the output end of the accumulator 2 and the input end of the pressure-stabilizing chamber 7; and a one-way feed valve 31 is provided at the interface between the three-way pipe 3 and the output end of the accumulator 2; a one-way discharge valve 32 is provided at the interface between the three-way pipe 3 and the input end of the pressure-stabilizing chamber 7; the output end of the pressure-stabilizing chamber 7 is connected to the input end of the homogenizing valve 1.

[0024] Among them: the low-pressure oil cylinder 4 is the actuator in the hydraulic transmission system, which is used to convert hydraulic energy into mechanical energy and drive the piston to reciprocate linearly. A low-pressure oil seal is arranged inside the low-pressure oil cylinder 4. A high-pressure seal 54 and a switch 53 are arranged inside the high-pressure cylinder 5.

[0025] In this example, a double-piston hydraulic cylinder is used. When the piston 51 reciprocates in the low-pressure oil cylinder 4, the inlet and outlet holes 52 at both ends are alternately in the oil inlet state and the oil outlet state, so that hydraulic energy is generated on one side while the other side releases hydraulic energy. The low-pressure oil seal divides the low-pressure oil cylinder into two hydraulic oil tanks, so that the oil in the two hydraulic oil tanks will not communicate with each other, so that the two hydraulic tanks can alternately generate sufficient hydraulic energy. The functions of the travel switch 53 are: 1. In order to achieve continuous reciprocating motion of the piston and realize automatic control; 2. When the piston moves to the travel switch position, it will stop and continue to move forward, and then reverse the operation to ensure that the piston will not damage the piston and other parts connected to the piston due to excessive hydraulic energy. The function of the high-pressure seal 54 is: when the piston reciprocates, it ensures that the material in the high-pressure cylinder 5 will not flow out due to the movement of the piston and lose mechanical energy. And ensure that in the process of converting hydraulic energy into mechanical energy, the material flow direction remains consistent with the piston movement direction to achieve the effect of boosting.

[0026] In practice, the working process of the homogenizer is as follows: the low-pressure oil cylinder 4 is started, so that the inlet and outlet holes 52 on one side of the high-pressure cylinder 5 are in the oil-in state, and the inlet and outlet holes 52 on the other side are in the oil-out state. One of the pistons 6 will be drawn out of the high-pressure cylinder 5, and the one-way feed valve 31 at this end is opened, so that the cylinder body of the high-pressure cylinder 5 at this end is filled with materials; the piston 6 at the other end is inserted into the high-pressure cylinder 5, so that the materials in the high-pressure cylinder 5 at that end move out of the high-pressure cylinder 5 through the one-way discharge valve 32. When the piston 6 at one end runs to the position of the travel switch 53, the discharge of the high-pressure cylinder 5 at this end is completed, and the oil supply at the other end is completed. At this time, the piston 6 runs in the opposite direction, and the high-pressure cylinder 5 at one end changes from feeding to discharging, and the high-pressure cylinder 5 at the other end changes from discharging to discharging, and the liquid materials are continuously sucked into the two high-pressure cylinders 5 alternately and transported to the pressure stabilizing chamber 7 alternately. The pressure value in the pressure stabilizing chamber 7 is always maintained at 300MPa-600MPa, and the bacteria contained in the material are killed under the pressure value. The sterilized material is output from the output end of the pressure stabilizing chamber 7 to the homogenizing valve 1 for homogenization operation.

Any changes or substitutions that can be easily thought of by any technician familiar with the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. The protection scope of the present invention shall be based on the protection scope of the claims.
