[0003] The invention relates to the technical field of sterilization equipment, and in particular to a fluid high-temperature sterilization equipment with small volume and good flexibility. Background Art

[0004] The sterilization methods for fluid foods (milk, juice, soy sauce, etc.) include physical sterilization (heating sterilization, radiation sterilization, etc.) and chemical sterilization (drug sterilization, etc.). The heating sterilization equipment includes plate-type sterilization equipment, sleeve-type sterilization equipment, etc. according to different structural forms. The heating sterilization equipment in the prior art is generally large in size and complex in structure. The manufacturing cost of the equipment is also relatively high. In addition, it is necessary to cooperate with the boiler to generate steam as a heat source for high-temperature sterilization. It is generally suitable for large-scale (daily processing volume reaches tens of tons to hundreds of tons) fluid sterilization. However, the demand for fluid sterilization in many companies is not that large, especially in some smaller micro-enterprises or stores. The use of the above-mentioned large-scale heating sterilization equipment is very uneconomical in terms of cost, and the cost of purchasing heating sterilization equipment and boilers is very high, which is not conducive to cost control. In addition, due to the large size of the heating sterilization equipment and the use of the boiler, the heating sterilization equipment cannot be moved at will, the requirements for the placement site are also higher, and the flexibility of use is poor, especially in the face of stores with smaller processing volumes, the flexibility of the heating sterilization equipment is higher. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fluid high-temperature sterilization device with small volume and good flexibility.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0007] A fluid high-temperature sterilization device with small size and good flexibility, comprising a sterilizer with a material inlet and a material outlet, wherein the sterilizer comprises a barrel, a heating device, and an annular coil;

The inner peripheral pipelines of the first tube, the second tube and the third tube respectively constitute the sterilization channel, the preheating channel and the cooling channel. The second tube, the first tube and the third tube are connected end to end and connected in sequence, so that the preheating channel, the sterilization channel and the cooling channel are connected in sequence. The inlet of the preheating channel constitutes the material inlet of the sterilizer, and the outlet of the cooling channel constitutes the material outlet of the sterilizer. The fluid material passes through the preheating channel, the sterilization channel and the cooling channel in sequence.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3As shown, a fluid high-temperature sterilization device, the sterilization device includes an equipment frame, a sterilizer with a material inlet and a material outlet arranged on the equipment frame, and a control system for controlling the operation of the sterilizer. The sterilizer includes a cylinder body formed with at least a first cavity k1, a second cavity k2, and a third cavity k3 from the inside to the outside (the cylinder body is made of stainless steel, the first cavity k1 is columnar, and the second cavity k2 and the third cavity k3 are annular), each cavity is independently arranged and not connected to each other, and the first cavity k1, the second cavity k2, and the third cavity k3 respectively have a sterilization channel, a preheating channel, and a cooling channel for the fluid material to pass through, the preheating channel, the sterilization channel, and the cooling channel are connected in sequence, and the fluid material passes through the preheating channel, the sterilization channel, and the cooling channel in sequence, the inlet of the preheating channel constitutes the material inlet of the sterilizer, and the outlet of the cooling channel constitutes the material outlet of the sterilizer;

[0025] In this example, the sterilizer further includes a first tube g1, a second tube g2 and a third tube g3 respectively arranged in the first cavity k1, the second cavity k2 and the third cavity k3, and the inner peripheral pipelines of the first tube g1, the second tube g2 and the third tube g3 respectively constitute a sterilization channel, a preheating channel and a cooling channel. The first tube g1, the second tube g2 and the third tube g3 are all annular coils, that is, the second tube g2, the first tube g1 and the third tube g3 are connected end to end and connected in sequence;

[0026] The sterilizer also includes a heating device for providing heat for the sterilization operation. The heating device includes a heating tube 22 arranged in the first cavity k1.

[0027] When the sterilization equipment of the present invention is performing a sterilization operation, the heating tube 22 provides heat energy for high-temperature sterilization; the first cavity k1, the second cavity k2, and the third cavity k3 are distributed in sequence from the inside to the outside, so the first tube g1, the second tube g2, and the third tube g3 are also distributed in sequence from the inside to the outside. Since the heating tube 22 is arranged in the first cavity k1, the temperature in the first cavity k1 is the highest, followed by the second cavity adjacent to it, and the temperature of the third cavity is relatively the lowest; the fluid material first enters the second tube g2 for preheating, and then enters the first tube g1 for high-temperature sterilization, and then enters the third tube g3 for cooling, which meets the three steps of preheating, sterilization, and cooling of high-temperature sterilization of the fluid material.

[0028] In this example, pure water is sealed in both the first and second chambers as a heat exchange medium (the pure water is not replaced except in the case of damage and repair). Pure water can avoid scaling under high temperature conditions and ensure the heat exchange performance of the medium. In addition, the sterilizer is also provided with a temperature sensor and a pressure gauge 12 for detecting the temperature and pressure in the first chamber, and real-time monitoring of the temperature and pressure in the first chamber (monitoring whether the medium is leaking).

[0029] The sterilization device also includes a regulating mechanism for regulating the temperature of the fluid in the cooling channel, and the regulating mechanism includes a heating water tank 31, a circulation pipe 30 connected between the heating water tank 31 and the third cavity k3, and a water pump 32 arranged on the circulation pipe 30. The third tube g3 in the third cavity is used to cool the fluid material flowing through it, so as to reach the required temperature (generally, the third cavity may not contain a medium, and some fluid materials need to reach 70°C to 80°C at this stage, and the function is that when the fluid enters the canned bottle, the canned bottle can be sterilized to a certain extent), and the regulating mechanism can effectively regulate the temperature in the third cavity.

[0030] In this example, the cylinder is installed horizontally on the equipment frame. The axis of the cylinder extends in the horizontal direction. In addition, the sterilization equipment also includes a high-pressure centrifugal pump 21 for pumping fluid materials into the sterilizer. The sterilization equipment integrates various devices necessary for sterilization, which is more convenient to use.

[0031] The cylinder body lies horizontally on the equipment rack, which is beneficial to the overall spatial arrangement of the sterilization equipment, the installation of various pipelines and interfaces, the reasonable distribution of space, and the convenience of maintenance; in addition, a first placement box x1, a second placement box x2 and a third placement box x3 are formed on the equipment rack, and the three placement boxes are distributed at right angles (such as Figure 3 As shown), the cylinder is installed in the first placement box x1, the high-pressure centrifugal pump 21 is installed in the second placement box x2, and the adjustment mechanism is installed in the third placement box x3. The space is reasonably utilized to minimize the size of the equipment. The overall length of the sterilization equipment of the present invention is 1.1m, the overall width is 0.9m, and the overall height is 0.8m.

[0032] Furthermore, the material outlet is connected to a discharge pipe 10, on which a safety valve 11, a thermometer 13 and a liquid angle seat valve 14 are provided. In addition, a pressure gauge 12 and a flow meter 15 are also provided on the material outlet pipe. The pressure gauge 12 can determine whether there is leakage in each channel, thereby ensuring the safe and effective operation of the sterilization equipment. The flow meter 15 can measure the fluid material that has completed the sterilization operation after passing through the sterilization equipment, providing a basis for subsequent production and packaging.

[0033] To sum up, the fluid high-temperature sterilization equipment of the present invention has changed the existing plate or sleeve heating method through the new structural design of the sterilizer. The distribution of the internal cavity of the cylinder and the distribution design of the preheating channel, sterilization channel and cooling channel meet the needs of preheating, sterilization and cooling of the fluid in the fluid sterilization operation. The simple and compact design of its overall structure greatly reduces the production cost of the sterilization equipment. Moreover, through the structural design of the sterilizer, the overall volume of the sterilization equipment is greatly reduced, which meets the user's demand for flexibility when using the equipment and meets the user's sterilization needs for small batches of fluid materials, which is beneficial to cost control. In addition, through the structural design of the sterilizer of the present invention, the sterilizer can have its own heat source, so there is no need to obtain heat source from the outside, thus eliminating the use of boilers and reducing the cost of use.

[0034] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them, but it does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
