Description

Technical Field

[0001] The utility model belongs to the technical field of dairy production and processing equipment, and in particular relates to a glass bottle disinfection system for yogurt processing. Background Art

[0002] In the processing and production of dairy products, glass bottles used for filling are indispensable containers. Before filling and use, glass bottles must first be cleaned, disinfected and sterilized by a disinfection system to reduce the contamination of dairy products by impurities and microorganisms in the bottle and ensure the safety of the product. However, there are two problems with the currently used glass bottle disinfection system. First, the alkali solution used for disinfection has a high temperature of 70-75°C after disinfecting the glass bottle. The alkali solution is easy to volatilize at high temperature, which reduces the concentration. If it is recycled, it will lead to insufficient disinfection of the glass bottle and the microorganisms of the product in the bottle will not meet the standards. Directly discharging the alkali solution will waste resources and increase production costs. Second, the water source used for cleaning after alkali disinfection is currently tap water. If the tap water source is unstable, there is still a risk of microbial contamination of the product. Utility Model Content

[0010] Compared with the prior art, the utility model has the following beneficial effects: 1. The utility model uses a heat exchanger to cool down the high-temperature alkali solution after disinfection, so as to prevent the alkali solution from volatilizing and reducing its concentration due to the high temperature. At the same time, the buffer tank can collect and store the alkali solution after disinfection and cooling, so that the alkali solution can be recycled, which can reduce production costs and improve the disinfection pass rate of glass bottles; 2. The utility model is connected to the pure water production device separately through a pipeline, which provides a stable and pure water source for cleaning the glass bottles after disinfection, eliminates the hidden danger of microbial contamination of the product when the water source is unstable, and further improves the disinfection pass rate of the glass bottles. At the same time, the water after cleaning is pumped back into the raw water tank by the return pump, providing a part of the water source for the pure water production device, so that water resources can be recycled, further reducing production costs.
