Embodiment Construction

[0022] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0023] Figure 1 ~ Figure 3 The schematic diagram of the off-line sterilization method process of the respirator on the buffer tank provided by the present invention, the respirator is installed on the respirator port on the buffer tank of the filling machine, and the respirator hand valve is housed below the respirator, and the buffer tank The offline sterilization method for respirators on the Internet consists of the following 3 steps:

[0024] Step 1: Combine figure 1 , remove the respirator and respirator hand valve combination 1, the respirator port on the buffer tank 2 is sealed with a stuffy plate, and then the buffer tank 2 can be automatically sterilized online. The online sterilization of the buffer tank refers to the online sterilization of the buffer tank through internal steam circulation after the respirator is re...

Abstract

The invention provides an offline sterilization method for a breather on a buffer tank. The method comprises the following steps: removing a combination of the breather and a breather hand valve, sealing a breather opening in the buffer tank by using a sealing plate, and automatically cleaning and sterilizing the buffer tank; then mounting an auxiliary hand valve below the breather hand valve, opening the breather hand valve, closing the auxiliary hand valve, and wholly putting and sterilizing the combined breather, breather hand valve and auxiliary hand valve in a sterilization cabinet; detaching the auxiliary hand valve under level-A laminar flow of a filling machine after the whole sterilization operation of the combined breather, breather hand valve and auxiliary hand valve is finished, and mounting the combination of the breather and the breather hand valve on the breather opening in the buffer tank. According to the method provided by the invention, the defects in the prior art are overcome, complete sterilization of the breather can be realized, the sterilization program is simplified, the time is saved, the production efficiency is improved, the cost is reduced, and sterile requirements can be guaranteed.

Description

technical field [0001] The invention relates to an off-line sterilization method for a respirator on a buffer tank, and belongs to the technical field of filling buffer tanks. Background technique [0002] The sterilization methods of the respirator on the filling buffer tank are generally divided into two methods: online sterilization and offline sterilization. Sterilization-in-line can reduce the annoyance of human disassembly and installation, as well as possible personnel-involved contamination during the process. However, the buffer tank will be sterilized on-line because the entire tank is under A-level laminar flow, and a large amount of heat will be emitted to the environment during the tank sterilization process, which will affect the local environment of the A-level area to a certain extent. temperature and humidity, which may encourage the growth of microorganisms. And because there are many pneumatic valves in the A-level area in the automatic control system, a...
