Description

Technical Field

[0001] The utility model relates to the technical field of seasoning production and processing, in particular to a bottle drying device for a seasoning bottle. Background Art

[0002] Seasoning, also known as condiments, refers to food ingredients that are added in small quantities to other foods to improve the taste, including various single seasonings such as soy sauce, salt, and sauce, and compound seasonings such as chicken seasoning. There are many types. Some liquid seasonings, such as soy sauce and vinegar, are sealed and packaged in glass bottles during the production and processing process in order to maintain the freshness and taste of the seasoning and help extend the shelf life of the seasoning. After the glass packaging bottles used to fill the seasoning are produced, the seasoning bottles will be cleaned and disinfected before filling the seasoning and using them. After cleaning and disinfection, a bottle drying device is also required to clean and dry the seasoning bottle.

[0003] According to a drying device for bottled oral liquid packaging disclosed in Patent No. 202222144976.9, the oral liquid bottle can enter the fixed seat, and the first inclined portion can allow the oral liquid bottle to enter the fixed seat better. When the oral liquid bottle enters the fixed seat, the movable block will be squeezed by the clamping sleeve, so that the movable block will squeeze the spring, and then the spring will restore its deformation, so that the clamping sleeve can clamp the oral liquid bottle.

[0004] When the above-mentioned drying device is used to dry the bottle bodies of packaging bottles, a single fixed seat clamping assembly is arranged on the conveying assembly.

The repetitive operation rate is high and the efficiency is low. When placing the packaging bottles, the packaging bottles need to be aligned with the inside of the clamping assembly before they can be placed. The operation is relatively cumbersome and there are shortcomings. There is no measure to perform batch clamping and limiting when the packaging bottle bodies are conveyed and dried.

[0005] Now, a novel bottle drying device for seasoning bottles is proposed to solve the above-mentioned disadvantages. Utility Model Content
