Cooling box for tunnel sterilizing dryer and dryer of cooling box

Abstract

The invention discloses a cooling box for a tunnel sterilizing dryer, comprising a cooling box body, a return air passage in the cooling box body, as well as a cooling fan, a cooling laminar flow cover and a bottle body conveying mechanism which are sequentially arranged in the cooling box body from top to bottom; an air discharge assembly communicated with the return air passage is arranged at the outer side of the bottom of the cooling box body, the outlet end of the return air passage is arranged at one side of an air inlet of the cooling fan, a cooling assembly is arranged in the return air passage, and an air supplement outlet for communicating the air inlet of the cooling fan and the outside is arranged on the cooling box body. The invention also discloses a tunnel sterilizing dryer, comprising a preheating section assembly, a high-temperature section assembly and a cooling section assembly which are arranged sequentially, and the cooling box is arranged on the cooling section assembly. The cooling box for the tunnel sterilizing dryer and the tunnel sterilizing dryer have the advantages that the structure is simple and compact, the cost is low, the usage is reliable, the cooing effect is better, and the sterilizing and drying effect of a bottle body on a high-temperature section can be enhanced.

Description

technical field [0001] The invention mainly relates to the fields of packaging machinery and equipment for food and pharmacy, and in particular refers to a cooling box of a tunnel-type sterilizing dryer and a dryer thereof. Background technique [0002] In food, pharmaceutical and other packaging machinery industries, the tunnel-type sterilizing dryer is mainly used for drying and sterilizing depyrogenation of medicine bottles. According to different structures and functions, the dryer is divided into a preheating section, a high-temperature section and a cooling section. , the bottle output from the cooling section is transported to the filling chamber by the conveyor belt for filling. In order to ensure the cleanliness during filling, the filling chamber needs to maintain a positive pressure environment, so the air pressure in the filling chamber is usually higher than that of the cooling section. In order to prevent the airflow in the cooling section from entering the fi...

Problems solved by technology

However, because the airflow in the cooling section is an internal circulation, the exhaust fan is installed in the cooling box to exhaust the air, and the cooling box forms a negative pressure, so that a large amount of gas in the high temperature section flows into the cooling box of the cooling section, thereb
