Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 to 3, the semi-water bath shell and tube pasteurizer according to the present embodiment includes: u type loose joint elbow 1, the evacuation mouth of pipe 2, standpipe 3, casing 4, baffling board 5, heat preservation 6, liquid level control valve 7, liquid level monitoring sight glass 8, steam admission pipe 9 and flange 10, the equipartition has a plurality of standpipe 3 to form the tubulation in the casing 4, 3 head and the tail of a plurality of standpipe adopt U type loose joint elbow 1 to connect into a pipeline, the equipartition has baffling board 5 from top to bottom in the casing 4, install the evacuation mouth of pipe 2 that communicates in with casing 4 on the outer wall on casing 4 upper portion, liquid level control valve 7 is installed to one side of casing 4 lower part, liquid level monitoring sight glass 8 is installed to the opposite side of casing 4 lower part, the lower part in casing 4 is installed to steam admission pipe 9, steam admission pipe 9 is by flange 10 and outside steam supply tube coupling, the outside cladding of casing 4 has heat preservation 6.

The liquid level control valves 7 are two, the first liquid level control valve 7 is installed at the bottom of the shell 4, and the second liquid level control valve 7 is installed on the shell 4 on the upper portion of the first liquid level control valve 7.

The liquid level monitoring sight glass 8 is three, and first liquid level monitoring sight glass 8 is installed on casing 4 on steam admission pipe 9 upper portion, and second liquid level monitoring sight glass 8 is installed at the lower extreme of casing 4, and third liquid level monitoring sight glass 8 is installed on casing 4 between first liquid level monitoring sight glass 8 and the second liquid level monitoring sight glass 8.

The main advantages of the semi-water bath tubular pasteurizer of this example are:

1. the heating and sterilizing temperature difference is small, and the damage to the effective components of the materials is effectively reduced. The material enters a semi-water bath tubular sterilizer from a single tubular, and the feeding temperature is continuously, stably and linearly increased from 70 ℃ to 90-95 ℃ for sterilization.

2. And (3) uniformly heating by adopting supersaturated secondary steam to prevent a coke tube. The ordinary tubular sterilizer controls the flow of steam through a valve and then enters a sterilizer shell, the steam is low-pressure superheated steam after passing through the valve, the temperature of the steam is still the temperature of steam in a cylinder, the steam directly acts on a sterilization tube nest to heat, and a coke tube is easily caused. The embodiment is that steam passes through steam admission pipe 9 and sprays in the comdenstion water, and steam produces supersaturation secondary steam after with the comdenstion water heating and gives the tubulation heating of disinfecting, and heats under vacuum condition, and the steam temperature is low, and consequently the material is heated evenly, mildly, can not coke the pipe.

3. The materials are heated and uniformly mixed without coking. The sterilizing tube nest composed of the vertical tubes 3 is adopted, so that the materials are turned and mixed more uniformly in the flowing process, and dead angles are avoided, and the tube nest is not easy to coke. The sterilizer can continuously work for 10-12 hours and is cleaned once, thereby reducing the cleaning times, improving the working efficiency and saving the operation cost.

4. And energy is saved. The steam flow path in the casing is changed according to a curve due to the use of a plurality of baffles 5 in the casing. The contact time of the steam and the materials is prolonged, and the heat exchange efficiency is improved. In addition, the heat-insulating layer 6 effectively reduces the heat loss on the surface of the sterilizer, thereby greatly saving energy and reducing the production cost.

5. The investment is low and the control is easy. The sterilizer has the advantages of simple structure, low equipment cost, and saved equipment investment and occupied space (see figure 1). The equipment is very easy to control, and the sterilization temperature can be controlled by means of a PLC (programmable logic controller) program during use, the steam flow of the sterilizer is adjusted according to the sterilization temperature detected by the temperature sensor, the sterilizer is ensured to work at the set sterilization temperature value all the time, and automatic control is realized.

6. The equipment occupies small area and is convenient to operate and maintain. The sterilizer is a long cylinder, can be vertically hung on the equipment platform, and is convenient to install and maintain. Especially, the U-shaped loose joint elbow 1 can be detached when coke pipes and pipe blockage possibly caused by steam faults and misoperation occur, and the dredging is directly carried out.

7. The sterilization effect is long-acting and stable. In the application and popularization, the indexes of various products can be well controlled no matter the whole milk powder or the formula milk powder is adopted, and before and after new standards are met, particularly, the infant formula milk powder added with auxiliary materials and more nutrients can effectively reduce the damage to the nutrient components, and the total number index of the produced finished product bacteria is stabilized within dozens to one or two hundred.

The above description is only the preferred embodiments of the present invention, and these embodiments are all based on the present invention, and the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
