Technical Field

[0001] The utility model relates to the technical field of lactic acid bacteria production equipment, in particular to a sterilizing device for lactic acid bacteria fermented milk. Background Art

[0002] Lactic acid bacteria fermented milk is a food made by mixing lactic acid bacteria (usually lactobacillus) with milk or other dairy products. When an appropriate amount of lactic acid bacteria culture agent (usually active lactobacillus) is added to milk, the lactic acid bacteria will convert the lactose in the milk into lactic acid during the fermentation process, thus souring the milk and forming the unique flavor of fermented milk.

[0003] Generally speaking, the optimal growth temperature of lactic acid bacteria is between 35°C and 45°C. In the fermentation process, in addition to beneficial lactic acid bacteria, there may be some harmful microorganisms, such as pathogenic bacteria and molds. Sterilization can avoid contamination by external microorganisms during the fermentation process, maintain the product quality and flavor of fermented milk, and help prevent adverse deterioration during the fermentation process, such as odor and discoloration. Therefore, sterilization equipment is needed in the production process of lactic acid bacteria.

[0026] See also Figure 1-Figure 4The sterilization device of lactic acid bacteria fermented milk shown in the figure comprises a fermentation barrel 1 which provides a fermentation space, the bottom surface of the fermentation barrel 1 is constructed with a circular through groove, and the bottom of the fermentation barrel 1 is sealed with a bottom ring 6, the bottom of the bottom ring 6 is sealed with a receiving frame 7, the outer periphery of the receiving frame 7 is fitted with a guide frame 11, a high-temperature sterilization component is fixed to the end surface of the guide frame 11 and extends to the inside of the guide frame 11, a connecting groove is constructed on the inner side of the fitting part of the receiving frame 7 and the guide frame 11, a symmetrically arranged fixing block 8 is fixed to the bottom of the receiving frame 7, and an electric lifting rod 9 is fixed between the surfaces of the fixing block 8, a partition 10 extending into the connecting groove for closing the connecting groove is fixed on the top of the piston rod of the electric lifting rod 9, and the cross-section of the partition 10 is semicircular, and an arc-shaped sealing plate 18 is fitted on the outer periphery of the fermentation barrel 1.

[0027] When performing the fermentation operation of lactic acid bacteria fermented milk, lactobacillus and milk products are put into the fermentation barrel 1 in advance, and the fermentation operation of the fermented milk is performed by controlling the temperature of the internal space of the fermentation barrel 1. After the fermentation is completed, the electric lifting rod 9 is retracted to move the partition 10 downward to open the connecting groove. At this time, the fermented lactic acid bacteria fermented milk can enter the guide frame 11 through the receiving frame 7.

[0028] Furthermore, if Figure 2-3 As shown, the high-temperature sterilization component includes an insulation frame 13 mounted on the surface of the guide frame 11, and an electric heating plate 14 is mounted on the surface of the insulation frame 13. The bottom of the electric heating plate 14 is connected to a high-temperature sterilization sheet 12 extending into the interior of the guide frame 11, and the side wall of the high-temperature sterilization sheet 12 is connected to an extension strip 19.

[0029] The extension strip 19 is made of copper sheet with good thermal conductivity so as to absorb the heat of the electric heating plate 14 and maintain a high temperature. Under the joint action of the high-temperature sterilization sheet 12 and the extension strip 19, the contact area with the lactic acid bacteria fermented milk can be greatly increased, and the sterilization operation can be performed through short-term high-temperature contact.

[0030] Furthermore, if Figure 3 As shown, a conical frame 15 is fixed to the end of the guide frame 11 , an end block 16 is sealed and installed at the end of the conical frame 15 , and a filling head 17 is installed between the bottom surface of the end block 16 and the bottom surface of the conical frame 15 .

[0031] The outflow of the lactic acid bacteria fermented milk can be conveniently controlled by the end block 16 and the filling head 17 so as to realize the filling operation.

A variety of fermented milk raw materials are poured into the delivery frame 5, and then the raw materials fall into the fermentation barrel 1 through the injection port. During the fermentation process, the electric lifting rod 9 is in an extended state. At this time, the connecting groove is closed under the action of the partition 10, so that the inside of the guide frame 11 is separated from the inside of the receiving frame 7. During fermentation, the stirring motor 3 is started as needed to drive the stirring rod 4 to rotate, so that the fermented milk raw materials are fully mixed, thereby improving the fermentation quality of the fermented milk.

When flowing through the end of the guide frame 11, the high-temperature sterilization sheet 12 and the extension strip 19 in a high-temperature state under the action of the electric heating plate 14 are fully in contact with the outflowing fermented milk, and a short-term high-temperature sterilization operation is performed on the fermented milk until the fermented milk is discharged through the filling head 17.
